EPIZYME, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. The Company

Epizyme, Inc. (collectively referred to with its wholly owned, controlled subsidiary, Epizyme Securities Corporation, as “Epizyme” or the “Company”) is a commercial-stage biopharmaceutical company that is committed to rewriting treatment for people with cancer through the discovery, development, and commercialization of novel epigenetic medicines. The Company aspires to change the standard of care for patients and physicians by developing targeted medicines with fundamentally new mechanisms of action directed at specific causes of hematological malignancies and solid tumors.

Through September 30, 2021, in addition to revenues from product sales, the Company has raised an aggregate of $1,560.6 million to fund its operations. This includes $268.8 million of non-equity funding through its collaboration agreements, $368.1 million of funding, consisting of $150.0 million in equity funding received through agreements with RPI Finance Trust, or RPI, and $218.1 million in debt financing received through a loan agreement with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership (as transferee of BioPharma Credit Investments V (Master) LP’s interest as a lender) (the "Lenders"), $847.7 million from the sale of common stock and series A convertible preferred stock in the Company’s public offerings and at-the-market offerings and $76.0 million from the sale of redeemable convertible preferred stock in private financings prior to the Company’s initial public offering in May 2013. As of September 30, 2021, the Company had $221.3 million in cash, cash equivalents and marketable securities.

In 2020, the Company’s EZH2 inhibitor, tazemetostat, was approved in the United States as TAZVERIK for the treatment of epithelioid sarcoma, or ES, and follicular lymphoma, or FL. Commercial sales of TAZVERIK for the treatment of ES commenced in the first quarter of 2020 and commercial sales of TAZVERIK for the treatment of FL commenced near the end of the second quarter of 2020.

The Company commenced active operations in early 2008. Since its inception, the Company has generated an accumulated deficit of $1,189.2 million through September 30, 2021 and will require substantial additional capital to fund its research, development, and commercialization efforts. The Company is subject to risks common to companies in the biotechnology industry, including, but not limited to, risks of failure of commercialization, clinical trials and preclinical studies, the need to obtain additional financing to fund the future development and commercialization of tazemetostat and the rest of its pipeline, the need to obtain marketing approval for its product candidates, the need to successfully commercialize and gain market acceptance of TAZVERIK and of any product candidates that may be approved in the future, the impact of the COVID-19 pandemic on the Company’s business, results of operations, and financial condition, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations and ability to transition from clinical-stage manufacturing to commercial-stage production, marketing, and sale of products.

 

Operating Cost Reduction

On August 9, 2021, the Company announced a cross-functional reduction of approximately 11% of its then current workforce under a cost reduction plan. Affected employees were offered separation benefits, including severance payments along with temporary healthcare coverage assistance. The severance and termination-related costs total approximately $2.0 million, $1.6 million of which were recorded as selling general and administrative expenses and $0.4 million of which was recorded as research and development expenses in the third quarter of 2021. The Company expects that payments of these costs will be made through August 2022.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, or the Annual Report.

The unaudited condensed consolidated financial statements include the accounts of Epizyme, Inc. and its wholly owned, controlled subsidiary, Epizyme Securities Corporation. All intercompany transactions and balances of subsidiaries have been eliminated in consolidation. In the opinion of management, the information furnished reflects all adjustments, all of which are of a normal and

9


 

recurring nature, necessary for a fair presentation of the results for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the condensed consolidated financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The three months ended September 30, 2021 and 2020 are referred to as the third quarter of 2021 and 2020, respectively. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period.

Use of Estimates

The preparation of these condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities, as of the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results and outcomes may differ materially from management’s estimates, judgments and assumptions.

Significant Accounting Policies

The significant accounting policies used in preparation of these condensed consolidated financial statements for the three and nine months ended September 30, 2021 are consistent with those discussed in Note 2 to the consolidated financial statements in the Annual Report and are updated below as necessary.

Going Concern

At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company is required to make certain additional disclosures if it concludes substantial doubt exists about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued and such doubt is not alleviated by the Company’s plans or when the Company's plans alleviate substantial doubt about the Company’s ability to continue as a going concern. The Company’s evaluation entails analyzing prospective operating budgets and forecasts for expectations of the Company’s cash needs, and comparing those needs to its available cash, cash equivalents and marketable securities.

The Company has recurring losses and expects to have recurring losses for the foreseeable future with the continued commercialization of TAZVERIK in ES and FL, the development of tazemetostat in other indications, and the development of the Company’s other product candidates. In addition, the Company has experienced and continues to experience challenges in the continued commercialization of TAZVERIK resulting from the ongoing COVID-19 pandemic, which the Company believes has had an adverse impact on TAZVERIK revenues. In response to the challenges that the Company has continued to face since the Company commenced its launch of TAZVERIK in FL in June 2020, the Company implemented an operational cost reduction plan that was announced on August 9, 2021 and continues to evaluate its costs on an on-going basis with the intent to streamline such costs.

The analysis of the Company’s ability to continue as a going concern for the third quarter of 2021 included consideration of the Company’s current cash needs, including its research and development plans, commercialization activities associated with the continued commercialization of TAZVERIK in the ES and FL indications, its existing debt service obligations, anticipated cost savings resulting from the August 2021 operational cost reduction plan, including ongoing efforts to eliminate costs not related to the Company’s strategic focus. The analysis included forecasted product revenues from sales of TAZVERIK. Such estimates of future sales contain significant judgment as TAZVERIK was first launched in the first half of 2020 and there is little history with which to base such estimates. In addition, the Company’s ongoing efforts to eliminate costs not related to the Company’s strategic focus contains uncertainties as to whether the Company can attain such benefits. Based on the analysis, the Company concluded that its available cash, cash equivalents and marketable securities as of September 30, 2021 will be sufficient to fund current planned operations and capital expenditure requirements and pay our debt service obligations as they become due into the fourth quarter of 2022 which is at least 12 months from the filing date of this Quarterly Report on Form 10-Q with the SEC. The Company’s current operating plan is based on assumptions that may prove to be wrong, and the Company could use its capital resources sooner than it expects, in which case the Company would evaluate further reductions in its expenses or obtaining additional financing sooner than it otherwise would, which additional financing may not be available or may only be available on terms that are not acceptable to the Company.

Recently Adopted Accounting Pronouncements

 

Revenue Recognition – Collaboration Revenue

 

In November 2018, the FASB, issued ASU 2018-18, Collaborative Arrangements, or ASC 808, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. The new standard is effective in the first quarter of fiscal 2021.

 

The Company adopted ASC 808 effective in the first quarter of fiscal 2021 and the Company’s adoption of this standard did not have a material effect on the Company’s condensed consolidated statements of operations and comprehensive loss or condensed consolidated statements of cash flows.

 

Income Taxes

 

In December 2019, the Financial Accounting Standards Board, or the FASB, issued ASU 2019-12, Income Taxes, or ASC 740, which simplifies the accounting for income taxes. The new standard is effective in the first quarter of fiscal 2021.

 

The Company adopted ASC 740 effective in the first quarter of fiscal 2021 and the Company’s adoption of this standard did not have a material effect on the Company’s condensed consolidated statements of operations and comprehensive loss or condensed consolidated statements of cash flows.

 

Revenue Recognition

 

The Company recognizes revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. For a further discussion of accounting for net product revenue see Note 3, Product Revenue, Net.

 

Other Revenue

 

Other revenue consists of revenue from the sales of tazemetostat active pharmaceutical ingredient (API) and drug product to the Company’s licensees or collaborators. The Company recognizes revenue on tazemetostat API and drug product when control has transferred under the terms of each agreement.

Cost of Revenues

 

Cost of revenues primarily consists of costs related to the sales of TAZVERIK and sales of tazemetostat API and drug product to the Company’s licensees or collaborators. These costs include materials, labor, manufacturing overhead, amortization of milestone payments, and royalties payable on net sales of TAZVERIK. Cost of revenues for the nine months ended September 30, 2021 included approximately $0.8 million related to sales of tazemetostat drug product. There were no sales of tazemetostat drug product during the three months ended September 30, 2021 or during the three and nine months ended September 30, 2020.

Accounts Receivable

The Company extends credit to customers based on its evaluation of the customer’s financial condition. The Company records receivables for all billings when amounts are due under standard terms. Accounts receivable are stated at amounts due net of applicable prompt pay discounts and other contractual adjustments as well as an allowance for doubtful accounts. The Company assesses the need for an allowance for doubtful accounts by considering a number of factors, including the length of time trade accounts receivable are past due, the customer’s ability to pay its obligation and the condition of the general economy and the industry as a whole. The Company will write off accounts receivable when the Company determines that they are uncollectible. In general, the Company has experienced no significant collection issues with its customers.

11


 

Inventory

 

The Company outsources the manufacturing of TAZVERIK and uses contract manufacturers to produce the raw and intermediate materials used in the production of TAZVERIK as well as the finished product. The Company currently has one supplier qualified for each step in the manufacturing process and is in the process of qualifying additional suppliers.

Inventory is composed of raw materials, intermediate materials, which are classified as work-in-process, and finished goods, which are goods that are available for sale. The Company states inventory at the lower of cost or net realizable value with the cost based on the first-in, first-out method. Inventory is classified as long-term when it is expected to be utilized beyond the Company’s normal operating cycle and is included in restricted cash and other assets on the Company's condensed consolidated balance sheets. If the Company identifies excess, obsolete or unsalable items, it writes down its inventory to its net realizable value in the period in which the impairment is identified. These adjustments are recorded based upon various factors related to the product, including the level of product manufactured by the Company, the level of product in the distribution channel, current and projected demand, the expected shelf-life of the product and firm inventory purchase commitments. Shipping and handling costs incurred for inventory purchases are included in inventory costs and costs incurred for product shipments are recorded as incurred in cost of revenue.

Prior to receiving its first approval from the U.S. Food and Drug Administration, or FDA, on January 23, 2020 to sell TAZVERIK, the Company expensed all costs incurred related to the manufacture of TAZVERIK as research and development expense because of the inherent risks associated with the development of a product candidate, the uncertainty about the regulatory approval process and the lack of history for the Company of regulatory approval of drug candidates.

Intangible Assets, Net

Intangible assets consist of capitalized milestone payments made to third parties under an in-license of patent rights upon receiving regulatory approval of TAZVERIK. The finite-lived intangible assets are being amortized on a straight-line basis over the expected time period the Company will benefit from the in-licensed rights, which is generally the patent life. Intangible assets are recorded at cost at the time of their acquisition and are stated in the Company’s condensed consolidated balance sheets net of accumulated amortization and impairments, if applicable. The amortization expense is recognized as cost of revenue in the Company’s condensed consolidated statement of operations and comprehensive loss. During the first quarter of 2020 the Company paid a $25.0 million milestone payment under its agreement with Eisai, Co., Ltd., or Eisai, upon regulatory approval of tazemetostat for ES. During the second quarter of 2020 the Company paid a $25.0 million milestone payment under its agreement with Eisai upon regulatory approval of tazemetostat for FL. Both regulatory milestones have been capitalized as intangible assets.

The Company recorded approximately $1.0 million and $3.1 million in amortization expense related to intangible assets, using the straight-line methodology, during the three and nine months ended September 30, 2021, respectively. The Company recorded approximately $1.0 million and $2.0 million in amortization expense related to intangible assets, using the straight-line methodology, during the three and nine months ended September 30, 2020, respectively. Estimated future amortization expense for intangible assets for the remainder of the year ended December 31, 2021 is $1.0 million and approximately $4.2 million per year thereafter.

 

The Company assesses its intangible assets for impairment if indicators are present or changes in circumstance suggest that impairment may exist. Events that could result in an impairment, or trigger an interim impairment assessment, include the receipt of additional clinical or nonclinical data regarding one of the Company’s drug candidates or a potentially competitive drug candidate, changes in the clinical development program for a drug candidate, or new information regarding potential sales for the drug. If impairment indicators are present or changes in circumstance suggest that impairment may exist, the Company performs a recoverability test by comparing the sum of the estimated undiscounted cash flows of each intangible asset to its carrying value on the Company's condensed consolidated balance sheets. If the undiscounted cash flows used in the recoverability test are less than the carrying value, the Company would determine the fair value of the intangible asset and recognize an impairment loss if the carrying value of the intangible asset exceeds its fair value.

 

12


 

During the three months ended June 30, 2021, the Company concluded the lower than anticipated current and projected future revenue, due to the impact of the COVID-19 pandemic as well as other factors, was an indicator that impairment may exist related to its finite-lived intangible assets. As a result, the Company performed a recoverability test and determined that the finite-lived intangible assets were recoverable. The Company’s quantitative assessment considered significant assumptions related to estimates of future TAZVERIK sales, offset by direct costs to derive the sales. The estimates of future TAZVERIK sales and associated costs include estimates of significant growth, however, these estimates are uncertain as the product was first launched in the first half of 2020 and due to the uncertainties associated with the ongoing COVID-19 pandemic. Given the limited history of sales and the inherent difficulty in making a long-range forecast, such estimates contain significant uncertainty. If the assumptions regarding forecasted revenue or the costs to derive such revenues prove to be inaccurate, the Company may be required to perform future impairment analyses and record an impairment charge for its intangible assets in future periods. 

3. Product Revenue, Net

The Company sells TAZVERIK in the United States principally to a limited number of specialty pharmacies, which dispense the product directly to patients, and specialty distributors, which in turn sell the product to hospital pharmacies and community practice pharmacies (collectively, healthcare providers) for the treatment of patients. The specialty pharmacies and specialty distributors are referred to as the Company’s customers.

Product revenue is recognized by the Company in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services when the customer obtains control of the product, which occurs at a point in time, typically when the product is received by the Company’s customers. The Company provides a right of return to its customers for unopened product for a limited time before and after its expiration date, which right of return lapses upon shipment to a patient. Healthcare providers to whom specialty distributors sell TAZVERIK hold limited inventory that is designated for patients, and the Company monitors inventory levels in the distribution channel to limit the risk of return.

 

Reserves for Variable Consideration

 

Revenues from product sales are recorded as product revenue at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established and which result from discounts, returns, chargebacks, rebates, co-pay assistance and other allowances that are offered within contracts between the Company and its customers, health care providers, payors and other indirect customers relating to the Company’s product sales. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a current liability (if the amount is payable to a party other than a customer). Where appropriate, these estimates take into consideration a range of possible outcomes that are probability-weighted for relevant factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which the Company is entitled based on the terms of the contract(s). The amount of variable consideration that is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known.

 

Trade Discounts and Allowances: The Company generally provides customers with discounts that include incentive fees that are explicitly stated in customer contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. In addition, the Company receives sales order management, data and distribution services from certain customers. To the extent the services received are distinct from the Company’s sale of products to the customer, these payments are classified in selling, general and administrative expenses in the Company's condensed consolidated statements of operations and comprehensive loss.

 

Product Returns: Consistent with industry practice, the Company generally offers customers a limited right of return based on the product’s expiration date for product that has been purchased from the Company, which lapses upon shipment to a patient. The Company estimates the amount of product sales that may be returned by customers and records this estimate as a reduction of revenue in the period in which the related product revenue is recognized. The Company currently estimates product return liabilities using available industry data and the Company’s own historical sales information, including its visibility into the product remaining in the distribution channel.

 

Provider Chargebacks and Discounts: Chargebacks for fees and discounts to healthcare providers represent the estimated obligations resulting from contractual commitments to sell products to qualified healthcare providers at prices lower than the list prices charged to customers who directly purchase the product from the Company. Customers charge the Company for the difference between what they

13


 

pay for the product and the ultimate selling price to the qualified healthcare providers. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and accounts receivable. Chargeback amounts are generally determined at the time of resale to the qualified healthcare provider by customers, and the Company generally issues credits for such amounts within a few weeks of the customer’s notification to the Company of the resale. Reserves for chargebacks consist of credits that the Company expects to issue for units that remain in the distribution channel at each reporting period end that the Company expects will be sold to qualified healthcare providers, and chargebacks that customers have claimed but for which the Company has not yet issued a credit.

 

Government Rebates: The Company is subject to discount obligations under state Medicaid programs and Medicare. The Company estimates its Medicaid and Medicare rebates based upon a range of possible outcomes that are probability-weighted for the estimated payor mix. These reserves are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability that is included in accrued expenses on the Company’s condensed consolidated balance sheets. For Medicare, the Company also estimates the number of patients in the prescription drug coverage gap for whom the Company will owe an additional liability under the Medicare Part D program. The Company’s liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but remains in the distribution channel inventories at period end.

 

Payor Rebates: The Company may contract with various private payor organizations, primarily insurance companies and pharmacy benefit managers, for the payment of rebates with respect to utilization of the Company’s products. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.

 

Other Incentives/Patient Assistance Programs: The Company also offers voluntary patient assistance programs such as co-pay assistance. Co-pay assistance programs are intended to provide financial assistance to qualified commercially insured patients with prescription drug co-payments required by payors. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue, but remains in the distribution channel inventories at period end.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist of accounts receivable from customers and cash held at financial institutions. The Company believes that such customers and financial institutions are of high credit quality.

For the three and nine months ended September 30, 2021 and 2020, net product revenue was primarily generated from four individual customers. Revenue earned from each customer as a percentage of net product revenue is as follows:

The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. At September 30, 2021, the balance in the Company’s accumulated other comprehensive loss was composed solely of activity related to the Company’s available-for-sale marketable securities. There were no realized gains or losses recognized on the sale or maturity of available-for-sale securities during the nine months ended September 30, 2021, and as a result, the Company did not reclassify any amounts out of accumulated other comprehensive loss for the same period.

The aggregate fair value of available-for-sale securities held by the Company in an unrealized loss position for less than twelve months as of September 30, 2021 was $33.5 million, which consisted of 13 commercial paper securities and 1 corporate note security. The aggregate unrealized loss for those securities in an unrealized loss position for less than twelve months as of September 30, 2021 was less than $0.1 million.

The Company does not intend to sell and it is unlikely that the Company will be required to sell the above investments before recovery of their amortized cost bases, which may be maturity. The Company has determined that there has been no material change in the credit risk of any of its investments. As a result, the Company determined it did not hold any investments that were impaired as of September 30, 2021. The Company reviews its portfolio of available-for-sale debt securities, using both quantitative and qualitative factors, to determine if declines in fair value below cost have resulted from a credit-related loss or other factors. If the decline in fair value is due to credit-related factors, a loss is recognized in net income, whereas if the decline in fair value is not due to credit-related factors, the loss is recorded in other comprehensive income (loss). The weighted-average maturity of the Company’s portfolio was approximately four months at September 30, 2021.

6. Fair Value Measurements

The Company’s financial instruments as of September 30, 2021 and December 31, 2020 consisted primarily of cash and cash equivalents, marketable securities and accounts receivable and accounts payable. As of September 30, 2021 and December 31, 2020, the Company’s financial assets recognized at fair value consisted of the following:

Cash equivalents and marketable securities have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third-party pricing services or other market observable data.

The Company measures its cash equivalents at fair value on a recurring basis, which approximates the net asset value per share. The Company classifies some of its cash equivalents within Level 1 of the fair value hierarchy because they are valued using observable inputs that reflect quoted prices for identical assets in active markets. The Company measures its marketable securities at fair value on a recurring basis and classifies those instruments and some cash equivalents within Level 2 of the fair value hierarchy. The pricing services used by management utilize industry standard valuation models, including both income- and market- based approaches and observable market inputs to determine the fair value of marketable securities and those cash equivalents classified within Level 2 of the fair value hierarchy.

The Company’s active pharmaceutical ingredient has a long shelf life and the Company’s finished drug product has a three-year expiry, however the realizability of the inventory is subject to forecasted future sales of TAZVERIK. The Company’s forecasted sales currently support the realizability of the Company’s inventory but are uncertain and could change in the future, which would require the Company to write down the value of such inventory. Due to the revisions to the Company’s forecast of future TAZVERIK sales during the quarter ended June 30, 2021, the Company classified a portion of its inventory as long-term.

 

As of September 30, 2021 the Company has not capitalized inventory costs related to its other drug development programs.

11. Leases

The Company enters into lease arrangements for its facilities as well as certain equipment. A summary of the arrangements is as follows:

Operating Leases

The Company leases office and laboratory space at Technology Square in Cambridge, Massachusetts under a Lease Agreement, dated as of June 15, 2012, as amended, or the Technology Square Lease, with ARE-TECH Square, LLC, a Delaware limited liability company.

In May 2017, the Company exercised its option to extend the term of the Technology Square Lease to November 30, 2022. Under the Technology Square Lease as amended, the Company agreed to pay a monthly base rent of approximately $0.2 million for the period commencing December 1, 2017 through May 31, 2018, with an increase on June 1, 2018 of approximately $33,000 and annual increases of approximately $9,000 on December 1 of each subsequent year until the last increase, which will occur on December 1, 2021.

On August 11, 2021, the Company, entered into a fifth amendment to the Technology Square Lease (the “Fifth Amendment”) with ARE-TECH Square, LLC. Under the Fifth Amendment, the Company extended the term of the Technology Square Lease through November 30, 2024. Under the Fifth Amendment, the Company will continue to pay the Landlord the current monthly base rent amount contemplated by the Technology Square Lease through November 30, 2022, with an increase commencing on December 1, 2022 and adjusting the monthly base rent amount to approximately $377,000 and an increase commencing on December 1, 2023 and adjusting the monthly base rent amount to approximately $388,000 through November 30, 2024. In addition, under the Fifth Amendment, the Landlord agreed to provide the Company with a tenant improvement allowance of up to approximately $430,000 if requested by the Company by August 11, 2022, subject to specified terms and conditions. In accordance with ASU 2016-02, Leases, or ASC 842, the Company accounted for the Fifth Amendment as a lease modification and remeasured the operating lease liability, resulting in an additional $7.0 million operating lease liability and right of use asset. Under the current terms of the Technology Square Lease, the Company does not have any further right to extend the term beyond November 30, 2024.

The Company has a $0.5 million letter of credit as a security deposit for the Technology Square Lease and has recorded cash held to secure this letter of credit as restricted cash and other assets on the Company's condensed consolidated balance sheets.

On August 16, 2019, the Company entered into a lease, or the Hampshire Street Lease, with BMR-Hampshire LLC, or BMR. The Hampshire Street Lease is for 33,525 rentable square feet of office space in Cambridge, Massachusetts. The Hampshire Street Lease commenced as of December 1, 2019. The Hampshire Street Lease has an initial term of seven years and four months from the commencement date and provides the Company with an option to extend the lease term for one additional five-year period. After a four-month period during which base rent was not payable, the Hampshire Street Lease provides for monthly rent payments starting at approximately $0.2 million and increasing 2.5% per year. In the event that the Company exercises its option to extend the lease term, the Hampshire Street Lease provides for monthly rent payments during the additional five-year period at the greater of the base rent rate at the end of the initial term or the then-current market rent.

The Company has a $1.0 million letter of credit in favor of BMR as a security deposit for the Hampshire Street Lease and has recorded cash held to secure this letter of credit as restricted cash and other assets on the Company's condensed consolidated balance sheets. In applying ASC 842, the Company determined the classification of the Hampshire Street Lease to be operating and recorded a lease liability and a right-of-use asset as of December 31, 2019.

The Company is required to pay certain variable costs to its landlords in addition to fixed rent. These costs include common area maintenance, real estate taxes, and parking and are included in lease expense.

12. Collaborations and Licensing Agreements

 

HutchMed

On August 7, 2021, the Company entered into a license agreement (the “HutchMed License Agreement”) with Hutchison China MediTech Investment Limited (“HutchMed”) for the development, manufacture and commercialization of tazemetostat, either as a monotherapy or as a part of combinations with other therapies, including HutchMed proprietary compounds, agreed by the parties under the HutchMed License Agreement (“Licensed Products”) for the treatment of epithelioid sarcoma, follicular lymphoma, diffuse large B-cell lymphoma in humans, and any additional indications agreed by the parties in accordance with the terms of the HutchMed License Agreement (the “Field”) in mainland China, Taiwan, Hong Kong and Macau (each, a “Jurisdiction”, and collectively, the “Territory”).

Agreement Structure

The Company has granted HutchMed licenses under patent rights and know-how controlled by the Company to enable HutchMed to develop and commercialize Licensed Products in the Field in the Territory. The licenses granted to HutchMed are co-exclusive with the Company with respect to the development of Licensed Products in the Field in the Territory and exclusive with respect to the commercialization of Licensed Products in the Field in the Territory. The Company also granted HutchMed a license under patent rights and know-how controlled by the Company to enable HutchMed to manufacture tazemetostat drug substance and drug product for the purpose of developing and commercializing Licensed Products in the Field in the Territory. The Company retains development and commercialization rights with respect to Licensed Products in the rest of the world outside of the Territory except for Japan. During the term of the HutchMed License Agreement, each party and its affiliates is prohibited from developing or commercializing in the Field in the Territory any other compound or product that inhibits, modulates or degrades EZH1, EZH2, or any other member of the polycomb repressive complex 2, including the EED protein, provided that, subject to limitations specified in the HutchMed License Agreement, HutchMed may develop, without the use of know-how or patent rights licensed by Epizyme, its existing preclinical compound that inhibits EZH1 and EZH2.

19


 

The Company has agreed to conduct a technology transfer of manufacturing technology to HutchMed to enable HutchMed to manufacture clinical and commercial quantities of tazemetostat drug substance and drug product to carry out its obligations and exercise its rights under the HutchMed License Agreement. Subject to the execution of a clinical supply agreement or commercial supply agreement, as applicable, and until the completion of the technology transfer to HutchMed, the Company has agreed to manufacture and supply HutchMed with tazemetostat drug substance and drug product in sufficient quantities for HutchMed’s development or commercialization activities for Licensed Products in the Field in the Territory.

HutchMed has agreed to use commercially reasonable efforts to carry out development activities in the Territory as agreed by the parties and to seek to obtain and maintain regulatory approval of the Licensed Products in the Territory. HutchMed agreed to use commercially reasonable efforts to commercialize Licensed Products in the Field in the Territory. HutchMed is responsible for all costs it incurs in developing, obtaining regulatory approval of, and commercializing Licensed Products in the Field in the Territory, including costs incurred by HutchMed in conducting clinical trials that only include clinical sites in the Territory. For global studies conducted by the Company that HutchMed elects to participate in by conducting any such study in the Territory, HutchMed will be responsible for enrolling and treating in the Territory 20% of the total number of study patients of such global study and will be responsible for costs for those patients enrolled and treated in such trials. HutchMed will also be responsible for 20% of the costs of such global studies that are not specific to any territory and the Company will be responsible for all other costs of such global studies. HutchMed has agreed to participate in the Company’s EZH-301 and EZH-302 global studies, however under certain circumstances where the EZH-302 global study is not considered a confirmatory trial for regulatory approval in China, the Company shall be responsible for the costs of the trial in the Territory.

Pursuant to the HutchMed License Agreement, the Company received a nonrefundable upfront payment of $25.0 million in September 2021. The Company is also entitled to milestone payments of up to $110.0 million in the aggregate for achievement of specified development and regulatory milestones with respect to Licensed Products in the Territory, and up to $175.0 million in the aggregate for achievement of specified sales milestones in the Territory with respect to the Licensed Products. The Company will also be entitled to receive tiered royalties, ranging from a mid-teens percentage to a low twenties percentage based on HutchMed’s cumulative annual net sales, if any, of Licensed Products in the Territory. Royalties are payable for each Licensed Product commencing on the first commercial sale of the applicable Licensed Product and ending, on a Jurisdiction-by-Jurisdiction basis, on the latest of expiration of specified patent coverage, expiration of specified regulatory exclusivity or a specified period following the first commercial sale in such Jurisdiction and may be reduced in various circumstances.

Under the HutchMed License Agreement, the Company issued a warrant to HutchMed (the “HutchMed Warrant”) , exercisable at any time prior to August 7, 2025 for up to 5,653,000 shares of the Company’s common stock at an exercise price of $11.50 per share. On September 21, 2021 the Company filed with the SEC a registration statement on Form S-3 registering for resale the shares of the Company’s common stock issuable upon exercise of the HutchMed Warrant in accordance with the HutchMed Warrant. Such registration statement on Form S-3 was declared effective by the SEC on September 29, 2021.

Unless earlier terminated, the HutchMed License Agreement will expire upon the expiration of the last royalty term for the last Licensed Product in the Field in the Territory. HutchMed may terminate the HutchMed License Agreement in its entirety for any or no reason upon 12 months’ prior written notice to the Company. Either party may, subject to specified cure periods, terminate the HutchMed License Agreement in the event of the other party’s uncured material breach, and under specified circumstances relating to the other party’s insolvency or if the other party or its affiliates challenges the validity, patentability, or enforceability of patent rights that are owned by or licensed to such party or its affiliates and that are subject to the licenses granted in the HutchMed License Agreement.

License Revenue

The Company evaluated the terms of the HutchMed License Agreement and first determined that the HutchMed Warrant should be accounted for pursuant to ASC 815, Derivatives and Hedging, with the HutchMed Warrant's fair value of approximately $13.0 million (Note 15) at execution considered outside of the revenue arrangement.

The Company identified the following performance obligations at the inception of the HutchMed License Agreement: (1) exclusive license with rights to develop, manufacture and commercialize tazemetostat in the Territory, (2) research and development services related to global trials, and (3) a material right related to the Company’s obligation to provide clinical supply of tazemetostat. In addition, the Company may also provide certain technology transfer services related to providing HutchMed with the capability to manufacture tazemetostat, for which the Company will receive reimbursement that approximates stand-alone selling price.

 

20


 

The Company evaluated the HutchMed License Agreement under ASC 606, Revenue from Contracts with Customers. Based on that evaluation, the $12.0 million of the up-front fee remaining after allocation to the HutchMed Warrant and the reimbursement to be received for its research and development services constituted the amount of the consideration to be included in the transaction price. In addition, should the EZH-302 global trial not be deemed a confirmatory trial for purposes of regulatory approval in China, the Company shall be responsible for reimbursing HutchMed for the costs of the portion of the EZH-302 global trial that will be performed in China. The Company concluded that this repayment provision represented variable consideration under the arrangement. Due to the uncertainty of potential repayment, which is based solely on the decision of a regulatory authority, the Company could not assert that it was probable that a significant reversal of revenue would not occur. As a result, the Company determined that the transaction price should be fully constrained. The Company will evaluate the application of the constraint on a quarterly basis and should the contingency be resolved without future payment to HutchMed for the EZH-302 global trial, the full upfront fee and any reimbursement of research and development services will be included in the transaction price. In addition, should the estimated payment to HutchMed for the EZH-302 global trial be determined to be less than the cumulative up-front fee and research and development reimbursement payments, such excess will be included in the transaction price.

None of the development or regulatory milestones have been included in the transaction price, as all such milestone amounts were fully constrained. As part of the Company's evaluation of the constraint, the Company considered numerous factors, including that receipt of the milestones is outside the control of the Company and contingent upon success in future clinical trials and the licensee’s efforts. Any consideration related to sales-based milestones (including royalties) will be recognized when the related sales occur as these amounts have been determined to relate predominantly to the license granted to HutchMed and therefore are recognized at the later of when the performance obligation is satisfied or the related sales occur.

The Company delivered the license during the third quarter of 2021 and expects that based on the estimated standalone selling price of the license, that the majority of the consideration in the arrangement will be allocated to the license performance obligation, once such consideration is no longer constrained. As the Company performs research and development services, it will recognize revenue as such services are performed, upon the transaction price no longer being fully constrained.

GSK

In January 2011, the Company entered into a collaboration and license agreement with Glaxo Group Limited (an affiliate of GlaxoSmithKline plc), or GSK, to discover, develop and commercialize novel small molecule HMT inhibitors directed to available targets from the Company’s platform. Under the terms of the agreement, the Company granted GSK exclusive worldwide license rights to HMT inhibitors directed to three targets. Additionally, as part of the research collaboration, the Company agreed to provide research and development services related to the licensed targets pursuant to agreed upon research plans during a research term that ended January 8, 2015. In March 2014, the Company and GSK amended certain terms of this agreement for the third licensed target, revising the license terms with respect to candidate compounds and amending the corresponding financial terms, including reallocating milestone payments and increasing royalty rates as to the third target. Subsequent to a GSK strategic portfolio prioritization, the Company received notice in October 2017 that GSK terminated the agreement with respect to the third target, effective December 31, 2017, which returned all rights to that target to the Company. The two other targets, PRMT5 and PRMT1, continue to be subject to the agreement and were not impacted by the termination with respect to the third target. The Company substantially completed all research obligations under this agreement by the end of the first quarter of 2015 and completed the transfer of the remaining data and materials for these programs to GSK in the second quarter of 2015.

Agreement Structure

Under the agreement, the Company has received and recognized as collaboration revenue totaling $89.0 million, consisting of upfront payments, fixed research funding, research and development services and preclinical and research and development milestone payments. As of September 30, 2021, for the two remaining targets, the Company is eligible to receive up to $50.0 million in clinical development milestone payments, up to $197.0 million in regulatory milestone payments and up to $128.0 million in sales-based milestone payments. As a result of the termination of the agreement as it relates to the third target, the Company will receive no additional payments related to that target. In addition, GSK is required to pay the Company royalties, at percentages from the mid-single digits to the low double-digits, on a licensed product-by-licensed product basis, on worldwide net product sales, subject to reduction in specified circumstances. Due to the uncertainty of pharmaceutical development and the high historical failure rates generally associated with drug development, the Company may not receive any additional milestone payments or royalty payments from GSK. GSK became solely responsible for development and commercialization for each licensed target in the collaboration when the research term ended on January 8, 2015.

21


 

Collaboration Revenue

Through September 30, 2021, the Company has earned a total of $89.0 million in total collaboration revenue since inception of the GSK agreement, which the Company recognized as collaboration revenue in the condensed consolidated statements of operations and comprehensive loss. The Company did not recognize any collaboration revenue under the agreement in the three and nine months ended September 30, 2021 and 2020, respectively. The Company did not have any deferred revenue related to this agreement as of September 30, 2021 and 2020, respectively. Any future revenues pursuant to this arrangement will relate to any milestone payments and royalties received under the agreement with respect to the two remaining targets. All remaining milestone payments as of September 30, 2021 have been deemed not probable and therefore have not been recognized as revenue.

Eisai

In April 2011, the Company entered into a collaboration and license agreement with Eisai, under which the Company granted Eisai an exclusive worldwide license to its small molecule HMT inhibitors directed to the EZH2 HMT, including the Company’s product candidate tazemetostat, while retaining an opt-in right to co-develop, co-commercialize and share profits with Eisai as to licensed products in the United States.

As of December 31, 2014, the Company had completed its performance obligations under the original agreement.

In March 2015, the Company entered into an amended and restated collaboration and license agreement with Eisai (the “Eisai License Agreement”), under which the Company reacquired worldwide rights, excluding Japan, to its EZH2 program, including tazemetostat. Under the Eisai License Agreement, the Company is responsible for global development, manufacturing and commercialization outside of Japan of tazemetostat and any other EZH2 product candidates, with Eisai retaining development and commercialization rights in Japan, as well as a right to elect to manufacture tazemetostat and any other EZH2 product candidates in Japan, and a right of first negotiation for the rest of Asia. Eisai waived its right of first negotiation for the rest of Asia in 2018.

Under the original collaboration and license agreement, Eisai was solely responsible for funding all research, development and commercialization costs for EZH2 compounds. Under the Eisai License Agreement, the Company is solely responsible for funding global development, manufacturing and commercialization costs for EZH2 compounds outside of Japan, including the remaining development costs due under a companion diagnostics agreement with Roche Molecular Systems, Inc., or Roche Molecular, which was amended to assign all of Roche Molecular’s rights and obligations under the companion diagnostics agreement to Roche Sequencing, effective January 1, 2020. Eisai is solely responsible for funding Japan-specific development and commercialization costs for EZH2 compounds.

The Company recorded the reacquisition of worldwide rights, excluding Japan, to the EZH2 program, including tazemetostat, under the Eisai License Agreement, as an acquisition of an in-process research and development asset. As this asset was acquired without corresponding processes or activities that would constitute a business, had not achieved regulatory approval for marketing and, absent obtaining such approval, had no alternative future use, the Company recorded the $40.0 million upfront payment made to Eisai in March 2015 as research and development expense in the condensed consolidated statements of operations and comprehensive loss. The Company also agreed to pay Eisai up to $20.0 million in clinical development milestones, and up to $50.0 million in regulatory milestone payments, and royalties at a percentage in the mid-teens on worldwide net sales of any EZH2 product, excluding net sales in Japan. The Company is eligible to receive from Eisai royalties at a percentage in the mid-teens on net sales of any EZH2 product in Japan.

Pursuant to the Eisai License Agreement, the Company has paid total milestone payments of $70.0 million, $50.0 million of which related to regulatory approval of tazemetostat for ES and FL, which were capitalized as intangible assets on the Company’s condensed consolidated balance sheets.

 

In March 2021, the Company and Eisai entered into a supply agreement providing for the manufacture and supply to Eisai of tazemetostat drug product. Under the terms of the supply agreement, the Company also agreed to waive its right of exclusive supply of tazemetostat drug substance from the Company’s drug substance manufacturer. During the nine months ended September 30, 2021, the Company recognized $6.3 million related to the Company’s waiver of its exclusive right to supply of tazemetostat drug substance from the Company’s drug substance manufacturer and delivery of tazemetostat drug product in collaboration and other revenue. No such revenue was recognized in the three months ended September 30, 2021.

During the three and nine months ended September 30, 2020, Eisai purchased $3.7 and $4.4 million, respectively, of drug product from the Company at cost to facilitate development within Japan under the Eisai License Agreement which was recognized as a reduction to research and development expense.

22


 

As of September 30, 2021 and December 31, 2020, the Company had accounts receivable of less than $0.1 million for both periods, due from Eisai.

During the three and nine months ended September 30, 2021, the Company recorded $0.8 and $2.7 million, respectively, related to the worldwide royalties due under the Eisai License Agreement in cost of revenue based on U.S. sales of TAZVERIK. During the three and nine months ended September 30, 2020, the Company recorded $0.5 and $1.0 million, respectively, in cost of revenue related to the worldwide royalties due under the Eisai License Agreement based on U.S. sales of TAZVERIK. As of September 30, 2021 and 2020, $0.8 million and $0.5 million, respectively, in royalties were payable under the Eisai License Agreement. For additional information regarding certain of the Eisai royalties, see Note 13, Sale of Future Royalties.

Roche

In December 2012, Eisai and the Company entered into a companion diagnostics agreement with Roche Molecular, under which Eisai and the Company engaged Roche Molecular to develop a companion diagnostic to identify patients who possess certain activating mutations of EZH2. In October 2013, this agreement was amended to include additional mutations in EZH2. The development costs due under the amended agreement with Roche Molecular were the responsibility of Eisai until the execution of the amended and restated collaboration and license agreement with Eisai in March 2015, at which time the Company assumed responsibility for the remaining development costs due under the agreement. In December 2015, the Company and Eisai entered into a second amendment to the companion diagnostics agreement with Roche Molecular. The agreement was further amended in March 2018. Under the amended agreement, the Company was responsible for remaining development costs of $10.4 million due under the agreement as of March 2018 and Eisai agreed to reimburse the Company $0.9 million of this amount related to a regulatory milestone for Japan. In July 2019, the Company entered into a fourth amendment to the companion diagnostics agreement. Under the amended agreement, the Company and Roche Molecular agreed to divide a $1.0 million regulatory milestone for the United States into two separate milestone payments, of which $0.5 million was paid by the Company as part of the signed amendment, and the remaining $0.5 million was paid by the Company in December 2019 upon the satisfaction of certain conditions set forth in the fourth amendment to the companion diagnostics agreement. As part of this fourth amendment, Roche Molecular also assigned all of its rights and obligations under the companion diagnostics agreement to Roche Sequencing due to a reorganization at Roche group, and this assignment became effective as of January 1, 2020. As of September 30, 2021, the Company is responsible for the remaining development costs of $1.0 million due under the agreement. The $0.9 million that Eisai agreed to reimburse the Company related to a regulatory milestone for Japan was achieved as of June 30, 2020 and payment received in the fourth quarter of 2020. In addition, the Company paid $1.0 million for the achievement of a development milestone in the fourth quarter of 2020.

Under the agreement with Roche Sequencing, Roche Sequencing is obligated to use commercially reasonable efforts to develop and to make commercially available the companion diagnostic. Roche Sequencing has exclusive rights to commercialize the companion diagnostic. On June 18, 2020 the FDA approved the companion diagnostic that is intended to identify follicular lymphoma patients with an EZH2 mutation for treatment with tazemetostat.

The agreement with Roche Sequencing will expire when the Company and Eisai are no longer developing or commercializing tazemetostat. The Company and Eisai may terminate the agreement by giving Roche Sequencing 90 days’ written notice if the Company and Eisai discontinue development and commercialization of tazemetostat or determine, in conjunction with Roche Sequencing, that the companion diagnostic is not needed for use with tazemetostat. Any party may also terminate the agreement in the event of a material breach by any party, in the event of material changes in circumstances that are contrary to key assumptions specified in the agreement or in the event of specified bankruptcy or similar circumstances. Under specified termination circumstances, Roche Sequencing may become entitled to specified termination fees.

Boehringer Ingelheim

 

In November 2018, the Company entered into a collaboration and license agreement with Boehringer Ingelheim International GmbH (“Boehringer Ingelheim”) to discover, research, develop and commercialize small molecule compounds that are inhibitors of an undisclosed histone acetyltransferase, or HAT, target and an undisclosed helicase target, along with associated predictive biomarkers (the “Target Projects”). Under the terms of the agreement, the Company granted to Boehringer Ingelheim an exclusive, worldwide license to the undisclosed target inhibitors technology. The agreement also included reciprocal licenses to utilize each other’s know-how, patents and technologies for activities under the agreement. Further, each party was granted the license to develop, manufacture, commercialize and otherwise exploit any compound or product that successfully achieves start of lead optimization (“SoLO”). The Company was also obligated to provide R&D services through SoLO approval for both Target Projects, and to serve on the Joint Steering Committee (“JSC”) throughout the term of the contract. The parties were to jointly research and develop the shared helicase target program and will share commercialization activities within the United States. Boehringer Ingelheim had agreed to assume responsibility for commercialization outside of the United States. On December 21, 2020, the Company received written notice from Boehringer Ingelheim that it elected to terminate the Collaboration Agreement without cause, and in accordance with the terms of the Collaboration Agreement. The termination became effective on January 31, 2021. The Target Project for the helicase target and the reciprocal licenses terminated as of this date. The Company is entitled to pursue the HAT target and helicase target programs in all fields worldwide without further obligation to Boehringer Ingelheim.

 

Agreement Structure

 

Under the terms of the agreement, the Company received a $15.0 million upfront payment and $5.0 million in research funding for the costs to be incurred by the Company in connection with its research activities, payable quarterly in four equal installments during 2019. At its discretion, Boehringer Ingelheim had the option to extend the research period by up to one year, subject to the Company’s agreement to the specified research activities and additional research funding. During the third quarter of 2019, Boehringer Ingelheim’s option to extend the research period expired unexercised, and therefore the research period ended on December 31, 2019. In March 2020, the Company and Boehringer Ingelheim amended the agreement to extend the research period for the shared program targeting enzymes within helicase families with Boehringer Ingelheim providing research funding of $0.4 million. Additionally, in March 2020, the Company received notice of termination for the program targeting enzymes with HAT families, which program termination became effective in June 2020. In September 2020, the Company and Boehringer Ingelheim further amended the agreement to extend the research period for the shared program targeting enzymes within helicase families with Boehringer Ingelheim to provide research funding of $0.1 million. The additional research activities were completed prior to the end of 2020.

 

Collaboration Revenue

 

Through September 30, 2021, the Company has recognized $26.0 million in total collaboration revenue since the inception of this collaboration. During the three and nine months ended September 30, 2021, the Company did not recognize collaboration revenue under its agreement with Boehringer Ingelheim. During the three and nine months ended September 30, 2020, the Company recognized $0.1 and $0.4 million, respectively, in collaboration revenue under its agreement with Boehringer Ingelheim. The Company will not receive any additional revenue under the terms of its agreement with Boehringer Ingelheim.

 

As of September 30, 2021 and December 31, 2020, the Company did not have any deferred revenue or accounts receivable related to this agreement.

13. Sale of Future Royalties

On November 4, 2019, the Company entered into a loan agreement with BioPharma Credit PLC, or the Collateral Agent, and the Lenders, providing for up to $70.0 million in secured term loans to be advanced in up to three tranches, or the Loan Agreement. As of June 30, 2021, the Company had borrowed an aggregate principal amount under the first tranche of $25.0 million (the “Tranche A Note Payable”), the second tranche of $25.0 million (the “Tranche B Note Payable”), and the third tranche of $20.0 million (the “Tranche C Note Payable”) under the Loan Agreement. On November 3, 2020, the Company, the Collateral Agent and the Lenders amended and restated the Loan Agreement, (as amended and restated, the “Amended and Restated Loan Agreement”), to provide for, among other things, an additional secured term loan of $150.0 million, or the Tranche D Loan. On November 18, 2020, the Company borrowed the Tranche D Loan (see Note 14, Long-Term Debt). Under the Amended and Restated Loan Agreement the Company has the right to request up to an additional $150.0 million in secured term loans, subject to the approval of the Lenders, provided that the Company has not prepaid any outstanding term loans at the time of the Company’s request and such request is made before November 18, 2021.

24


 

On November 4, 2019, the Company also executed a purchase agreement (the “RPI Purchase Agreement”) with RPI. Pursuant to the RPI Purchase Agreement, the Company agreed to sell to RPI 6,666,667 shares of its common stock, a warrant to purchase up to 2,500,000 shares of common stock at an exercise price of $20.00 per share (the “Common Stock Warrant”), and all of the Company’s rights to receive royalties from Eisai with respect to net sales by Eisai of tazemetostat products in Japan pursuant to the Eisai License Agreement and any successor arrangement for Japan sales (the “Japan Royalty”, and collectively, the “Transaction”). In consideration for the sale of shares of common stock, the Common Stock Warrant and the Japan Royalty, RPI paid the Company $100.0 million upon the closing of the RPI Purchase Agreement. In addition, RPI agreed, in connection with RPI’s acquisition from Eisai of the right to receive royalties from the Company under the Eisai License Agreement, to reduce the Company’s royalty obligation by low single digits upon the achievement of specified annual net sales levels over $1.5 billion. In addition, under the RPI Purchase Agreement, the Company has the right to sell, and RPI has the obligation to purchase, subject to certain conditions, including a maximum purchase price of $20.00 per share, $50.0 million of shares of common stock at the Company’s option for an 18-month period from the date of execution of the RPI Purchase Agreement (the “Put Option”). In February 2020, the Company sold 2.5 million shares of its common stock to RPI, for an aggregate of $50.0 million in proceeds pursuant to the Put Option. Additionally, under the terms of the RPI Purchase Agreement, the founder and chief executive officer of RP Management, an affiliate of RPI, and a co-founder of Pharmakon Advisors LP, an affiliate of the Lenders, was elected as a director of the Company. As of September 30, 2021 and December 31, 2020, RPI and its affiliates owned approximately 9.0% and 9.0% of the Company’s common stock, respectively.

The Company accounted for the Loan Agreement and RPI Purchase Agreement as a single arrangement as RPI and the Lenders are related parties and the agreements were negotiated together. The aggregate proceeds of $125.0 million were allocated on a relative fair value basis, which approximated their respective actual fair values, to the four units of accounting pursuant to the transaction as follows: (1) $79.0 million to the common stock issued to RPI based on the closing price of the Company’s common stock on the date of the transaction, (2) $8.4 million to the Common Stock Warrant to purchase shares of common stock, based on the Black-Scholes option pricing model, (3) $12.6 million to the liability related to the sale of future royalties based on a discounted cash flow model and (4) $25.0 million to the Tranche A Note Payable based on the terms of the Loan Agreement. Transaction costs of $2.0 million were allocated directly to the units of accounting it relates to.

Although the Company sold all of its rights to receive the Japan Royalty, under the terms of the RPI Agreement, the Company continues to own all tazemetostat intellectual property rights and at execution had significant continuing involvement in the generation of these royalties. Due to the Company’s continuing involvement, the Company will continue to account for any royalties due as revenue and recorded the proceeds from this transaction as a liability (“Royalty Obligation”) that will be accreted using the effective interest method over the estimated life of the RPI Purchase Agreement.

As royalties are remitted to RPI from Eisai, the balance of the Royalty Obligation will be effectively repaid over the life of the Eisai License Agreement. In order to determine the accretion of the Royalty Obligation, the Company is required to estimate the total amount of future royalty payments to RPI over the life of the Eisai License Agreement. The $12.6 million recorded at execution will be accreted to the total of these royalty payments as interest expense over the life of the Royalty Obligation. At execution, the Company’s estimate of this total interest expense resulted in an effective annual interest rate of approximately 9.01%. This estimate contains significant assumptions that impact both the amount recorded at execution and the interest expense that will be recognized over the royalty period. The Company periodically assesses the estimated royalty payments to RPI from Eisai and to the extent the amount or timing of such payments is materially different than the original estimates, an adjustment will be recorded prospectively to increase or decrease interest expense. There are a number of factors that could materially affect the amount and timing of royalty payments to RPI from Eisai, and correspondingly, the amount of interest expense recorded by the Company, most of which are not within the Company’s control. Such factors include, but are not limited to, delays or discontinuation of development of tazemetostat in Japan, regulatory approval, changing standards of care, the introduction of competing products, manufacturing or other delays, generic competition, intellectual property matters, adverse events that result in governmental health authority imposed restrictions on the use of the drug products, significant changes in foreign exchange rates as the royalties remitted to RPI are made in U.S. dollars (USD) while the underlying Japan sales of tazemetostat will be made in currencies other than USD, and other events or circumstances that are not currently foreseen as tazemetostat is still under development in Japan and subject to regulatory approval. Changes to any of these factors could result in increases or decreases to both royalty revenues and interest expense. On June 23, 2021, Eisai announced that it had obtained manufacturing and marketing approval for the EZH2 inhibitor “Tazverik® Tablets 200 mg” (tazemetostat hydrobromide) in Japan with the indication of relapsed or refractory EZH2 gene mutation-positive follicular lymphoma (only when standard treatment is not applicable), which caused the Company to reassess the estimated future royalty payments to RPI. As of September 30, 2021, the Company’s assessment of the estimated future royalty payments to RPI resulted in a current effective interest rate of approximately 11.4%.

During the three and nine months ended September 30, 2021 and 2020, the Company recorded $0.4 million and $1.4 million, respectively, and $0.3 million and $0.9 million, respectively, of related non-cash interest expense.

 

14. Long-Term Debt

On November 4, 2019, the Company entered into the Loan Agreement, which provided for up to $70.0 million in secured term loans to be advanced in up to three tranches. The Company borrowed $70.0 million in the aggregate under the three tranches pursuant to the Loan Agreement. With the FDA’s June 2020 approval of tazemetostat for the treatment of FL in the United States, the Company also had the right, but not the obligation, to request up to an additional $300.0 million in secured term loans, subject to the approval of the Lenders, provided the Company has not prepaid any outstanding term loans at the time of such request and such request is made before November 18, 2021. On November 3, 2020, the Company entered into the Amended and Restated Loan Agreement with the Lenders. The Amended and Restated Loan Agreement provides for, among other things, an additional secured term loan of $150.0 million, or the Tranche D Loan. On November 3, 2020, the Company also delivered written notice to the Lenders to draw down the Tranche D Loan, which was funded on November 18, 2020. The Company paid a commitment fee of 2.00% of the original $70.0 million committed facility amount in November 2019 and 2% of the $150.0 million Tranche D Loan in November 2020, as well as expenses incurred by the Lender in executing the agreements.

The interest rate for the Tranche D Loan will be determined by reference to a Eurodollar rate plus 7.75% above such Eurodollar rate. The Eurodollar rate will have a 2.00% floor. The Tranche D Loan will be due in eight equal quarterly principal payments commencing on the 51st month anniversary of the date on which the Lenders fund the Tranche D Loan. All unpaid principal and interest under the Tranche D Loan will be due and payable on the 72nd month anniversary of the date on which the Lenders funded the Tranche D Loan.

The Amended and Restated Loan Agreement also amended the payment period principal and interest for the first three tranches of term loans. Under the original terms, the Company was required to make interest only payments on the outstanding obligation through February 28, 2023, and thereafter eight quarterly payments of principal and interest. Under the amended and restated terms, the Company is required to make interest only payments on the $70.0 million outstanding obligation through November 2023, and thereafter four quarterly payments of principal and interest. All unpaid principal and interest on the $70.0 million borrowed under the original Loan Agreement is due and payable in November 2024, the 60th month anniversary of the date on which the Lenders funded the first tranche of term loans. The interest rates for the existing tranches of term loans remain unchanged and will continue to be determined by reference to a Eurodollar rate plus 7.75% above such Eurodollar rate. The Eurodollar rate will have a 2.00% floor.

Under the Amended and Restated Loan Agreement the Company has the right to request from the Lenders, subject to the Lenders’ agreement to lend additional amounts to the Company, up to an additional $150.0 million, provided that the Company has not prepaid any outstanding term loans at the time of the Company’s request and such request is made before November 18, 2021.

Each of the four term loans may be prepaid before maturity in whole or in part, however there is a $50.0 million minimum prepayment for any prepayment of the loans. If the Company prepays any tranche of term loans, in whole or in part, during the first 36 months from the date on which the Lenders funded such tranche of term loans, then the Company must pay a prepayment premium equal to the greater of (x) a make-whole amount equal to the interest that would have accrued on the principal amount to be prepaid and (y) a premium equal to 0.03 multiplied by the principal amount to be prepaid. If the Company prepays a tranche of term loan, in whole or in part, between the 36th month and 48th month from the date on which the Lenders funded such tranche of term loans, then the Company must pay a prepayment premium equal to 0.02 multiplied by the principal amount to be prepaid. If the Company prepays a tranche of term loans, in whole or in part, between the 48th month and 60th month from the date on which the Lenders funded such tranche of term loans, then the Company must pay a prepayment premium equal to 0.01 multiplied by the principal amount to be prepaid.

26


 

The Amended and Restated Loan Agreement was accounted for as a debt modification based on a comparison of the present value of the cash flows under the terms of the debt immediately before and after the effective date of The Amended and Restated Loan Agreement, which resulted in a change of less than 10%. As a result, issuance costs paid to the Lenders in connection with The Amended and Restated Loan Agreement were recorded as a reduction of the carrying amount of the debt liability and unamortized issuance costs as of the date of the modification are amortized to interest expense over the repayment term of The Amended and Restated Loan Agreement.

The obligations under the Amended and Restated Loan Agreement, including the Company’s payment obligations in respect of the Tranche D Loan are secured by the first priority security interest in and a lien on substantially all of the assets of the Company, subject to certain exceptions, that the Company granted to the Lenders in connection with the first tranche of term loans under the Loan Agreement.

The Amended and Restated Loan Agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default applicable to the Company and its subsidiaries. If an event of default occurs and is continuing, the Collateral Agent may, among other things, accelerate the loans and foreclose on the collateral. The Company has determined that the risk of subjective acceleration under the material adverse events clause is not probable and therefore has classified the outstanding principal in non-current liabilities based on scheduled principal payments.

 

The Company has the following minimum aggregate future loan payments at September 30, 2021 (in thousands):

2021 At-the-Market Offering Program

27


 

On May 6, 2021, the Company entered into an Open Market Sale AgreementSM (“ATM Sale Agreement”), with Jefferies LLC (“Jefferies”) to sell, from time to time, shares of the Company's common stock having an aggregate offering price of up to $200.0 million through an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended, under which Jefferies would act as sales agent (the "ATM Offering").

Shares of Series A Preferred Stock will be entitled to receive dividends equal to (on an as-if-converted-to-common stock basis), and in the same form and manner as, dividends actually paid on shares of the Company’s common stock.

Liquidation Rights

Subject to the prior and superior rights of the holders of any senior securities of the Company, upon liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, each holder of shares of Series A Preferred Stock shall be entitled to receive, in preference to any distributions of any of the assets or surplus funds of the Company to the holders of common stock, an amount equal to $0.001 per share of Series A Preferred Stock, plus an additional amount equal to any dividends declared but unpaid on such shares, before any payments shall be made or any assets distributed to holders of any class of common stock.

If, upon any such liquidation, dissolution or winding up of the Company, the assets of the Company shall be insufficient to pay the holders of shares of the Series A Preferred Stock the amount required under the preceding sentence, then all remaining assets of the Company shall be distributed ratably to holders of the shares of the Series A Preferred Stock in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

Conversion

Each share of Series A Preferred Stock shall be convertible, at any time and from time to time from and after the issuance date, at the option of the holder thereof, into a number of shares of common stock equal to 10 shares of common stock, provided that the holder will be prohibited from converting Series A Preferred Stock into shares of the Company’s common stock if, as a result of such conversion, the holder, together with its affiliates and attribution parties, would own more than 9.99% of the total number of shares of common stock then issued and outstanding. The holder can change this requirement to a higher or lower percentage, not to exceed 9.99% of the number of shares of common stock outstanding, upon 61 days’ notice to the Company.

In February 2020, 12,200 shares of Series A Preferred Stock were converted to 122,000 shares of common stock.

Redemption

The Company is not obligated to redeem or repurchase any shares of Series A Preferred Stock. Shares of Series A Preferred Stock are not entitled to any redemption rights or mandatory sinking fund or analogous fund provisions.

Warrants

In November 2019, the Company issued the Common Stock Warrant for the purchase of up to 2,500,000 shares of Common Stock at an exercise price of $20.00 per share to RPI pursuant to the RPI Purchase Agreement (for additional information see Note 13, Sale of Future Royalties), which was classified as equity and recorded at its relative fair value of $8.4 million to additional paid-in capital on the Company's condensed consolidated balance sheets. The Common Stock Warrant remains outstanding as of September 30, 2021.

In August 2021, the Company issued the HutchMed Warrant to HutchMed under the HutchMed License Agreement, exercisable at any time prior to August 7, 2025 for up to 5,653,000 shares of the Company’s common stock at an exercise price of $11.50 per share. Under the HutchMed Warrant, the number of shares issuable under the warrant is reduced from 5,653,000 to 2,826,500 in the event that the HutchMed License Agreement is terminated by HutchMed at any time and for any reason or no; terminated by the Company for HutchMed's material breach of the HutchMed License Agreement; terminated by the Company in connection with a challenge by HutchMed of any of the patent rights licensed to HutchMed under the HutchMed License Agreement; or terminated by the Company in connection with an event of bankruptcy of HutchMed, in each case as more fully described in the HutchMed License Agreement. Due to this provision in the HutchMed Warrant, the Company concluded that the warrant does not meet the exception from derivative accounting pursuant to ASC 815, Derivatives and Hedging, which requires that the warrant be accounted for as a derivative. Accordingly, the Company recorded a warrant liability in the amount of approximately $13.0 million upon issuance of the HutchMed Warrant. The fair value of the HutchMed Warrant was determined using a Black-Scholes and Monte Carlo pricing model.

The HutchMed Warrant is subject to revaluation at each balance sheet date and any changes in fair value are recorded as a non-cash gain or (loss) in the Company's condensed consolidated statement of operations and comprehensive loss as a component of other income (expense), net until the earlier of the exercise or expiration of the HutchMed Warrant or upon the completion of a liquidation event. Upon exercise, the HutchMed Warrant is subject to revaluation just prior to the date of the warrant exercise and any changes in fair value are recorded as a non-cash gain or (loss).

The Company recorded non-cash gains of approximately $4.4 million during the three and nine months ended September 30, 2021 in its condensed consolidated statement of operations and comprehensive loss attributable to the decreases in the fair value of the warrant liability that resulted from a reduction in the Company's stock price as of September 30, 2021.
 

The following table rolls forward the fair value of the HutchMed Warrant liability, the fair value of which is determined by Level 3 inputs at inception on August 7, 2021, and as of September 30, 2021:

16. Stock-Based Compensation

The Company maintains one stock incentive plan, the 2013 Stock Incentive Plan, as well as the 2013 Employee Stock Purchase Plan.

In addition, during the three and nine months ended September 30, 2021, the Company granted options to purchase an aggregate of 80,000 shares of Epizyme common stock and 53,333 restricted stock units (RSUs) to two new employees as equity inducement awards outside of the Company's 2013 Stock Incentive Plan and material to the employees’ acceptance of employment with the Company. These equity awards were approved in accordance with Nasdaq Listing Rule 5635(c)(4), and these equity awards remained outstanding as of September 30, 2021. These options have an exercise price of $5.31 per share, which is equal to the closing price of Epizyme common stock on August 16, 2021, the grant date of these options. These inducement awards are included in stock-based compensation expense and the following tables.

 

Total stock-based compensation expense related to stock options, restricted stock units, shares issued under the employee stock purchase plan, and shares granted to non-employee directors in lieu of board fees was $6.2 million and $6.4 million for the three months ended September 30, 2021 and September 30, 2020, respectively, and $19.9 million and $21.2 million for the nine months ended September 30, 2021 and September 30, 2020, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our management’s discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, which have been prepared by us in accordance with accounting principles generally accepted in the United States, or GAAP, and with Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. This discussion and analysis should be read in conjunction with these condensed consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission on February 23, 2021 and in Part II, Item 1A. Risk Factors of this Quarterly Report on Form 10-Q, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Note on the COVID-19 Pandemic

The complex challenges created by the COVID-19 pandemic have had an adverse impact on our business, operations, and financial performance, and as such we continue to take steps to respond to these challenges and adjust our commercial strategy and operating plans accordingly.

We believe that the COVID-19 pandemic has had an adverse impact on sales of TAZVERIK since the June 2020 FDA approval of TAZVERIK for follicular lymphoma, or FL. Although our commercial and medical affairs field teams continue to use virtual formats as well as in-person interactions where possible in order to allow us to serve the needs of healthcare providers, patients and other stakeholders, the COVID-19 pandemic continues to negatively impact epithelioid sarcoma, or ES, and FL patient visits to physicians and subsequent new patient starts across all lines of treatment. In addition, the COVID-19 pandemic has negatively impacted the ability of our field-based teams to fully access ES and FL prescribers. These challenges continued through the third quarter of 2021.

In response, we are adjusting our commercial strategy, recognizing that some of the changes brought about by the COVID-19 pandemic, such as ongoing restrictions to access providers by traditional sales personnel, will likely persist after the resolution of the pandemic.

On August 9, 2021, we announced changes to our commercial strategy and organization and adjustments to our operating plans, including operating expense reductions throughout the organization. These changes are intended to accelerate the understanding and appropriate use of TAZVERIK by providers for patients with ES and FL as well as to focus the investment of company resources on what we believe to be our most important value-driving clinical trials and programs to support increased adoption of TAZVERIK in the longer term, including the generation of additional clinical data for TAZVERIK across treatment lines and in combinations.

Although the initiation, enrollment and completion of our ongoing and planned clinical trials have not been meaningfully disrupted, we are aware of the impact that COVID-19 continues to have on other clinical trials in our industry and there is a risk of material impact on the conduct of our clinical trials as well. We are continuing to work with our clinical trial sites to ensure study continuity, enable medical monitoring, facilitate study procedures and maintain clinical data and records, including the use of local laboratories for testing, home delivery of study drug and remote data and records monitoring.

To date, the COVID-19 pandemic has not had a material impact on our supply chain, and we currently have a consistent supply of tazemetostat and TAZVERIK that we believe will cover our ongoing clinical development as well as the ongoing commercialization for ES and FL. From time to time, however, we have experienced some occasional delays in connection with our clinical supply. As a proactive measure, we have taken certain steps to try to reduce the risk to our supply chain, such as advancing orders for long-lead items in anticipation of potential future delays or shortages. Because the ongoing COVID-19 pandemic could materially adversely impact our suppliers and result in delays or disruptions in our current or future supply chain, we are continuing to monitor and manage our supply chain accordingly.

We are implementing a multi-stage return to office plan, and in October 2021 we opened our facilities to all employees who expressed interest in participating in a return-to-office pilot program, which we expect to continue through the end of 2021. In the meantime, many of our employees continue to work in a remote operating model. Our laboratory scientists who engage in research activities now have full access to our laboratories. We plan to use our pilot program to further evaluate this hybrid model and based on that evaluation formulate how we will move forward. We are implementing our return to office plan and making these evaluations based on guidance from federal, state and local government authorities, and we expect that some form of a hybrid model will exist for us in the near future.

33


 

We plan to continue to assess the potential duration, scope and severity of the COVID-19 pandemic and its impacts on our business, operations and financial performance, and to continue to work closely with our third-party vendors, collaborators and other parties in order to seek to continue to advance our commercialization efforts of TAZVERIK and to continue to advance the development of our pipeline, while making the health and safety of our employees and their families, healthcare providers, patients and communities a top priority. Due to the evolving and uncertain global impacts of the COVID-19 pandemic, however, we cannot precisely determine or quantify the impact that this pandemic has had on our business, operations and financial performance or the impact that this pandemic will have in 2021 and beyond.

Please refer to our risk factors set forth in Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission on February 23, 2021 and in Part II, Item 1A. Risk Factors of this Quarterly Report on Form 10-Q for further discussion of risks related to the COVID-19 pandemic.

Operating Expense Reductions

In response to the challenges we have continued to face since we commenced the launch of TAZVERIK in FL in June 2020, we continue to implement changes to our commercial strategy and organization in an effort to accelerate commercial adoption of TAZVERIK in appropriate patients while also pursuing our research and broader corporate objectives.

On August 9, 2021, we announced a cross-functional reduction of our 2021 budgeted headcount by approximately 20%, which included approximately 11% of our then-current workforce under the cost reduction plan. Affected employees were provided separation benefits, including severance payments along with temporary healthcare coverage assistance. The severance and termination-related costs were approximately $2.0 million. We recorded these costs in the third quarter of 2021 and expect that payments of these costs will be made through August 2022. Our plan is to continue to monitor and further reduce our operating expenses in the fourth quarter of 2021 and through our 2022 budgeting process, which is underway.

As part of this plan, we are prioritizing our investment of company resources in what we believe to be our most important value-driving clinical trials and programs. These most important value-driving clinical trials and programs include our EZH-302 (SYMPHONY-1), EZH-1401 (SYMPHONY-2), and EZH-1101 (CELLO-1) trials, our two signal-finding basket studies (EZH-1301, our solid tumor basket study, and EZH-1501, our hematology basket study) and our novel SETD2 inhibitor EZM0414 program. To provide ongoing investment in these important programs, we plan to continue to manage our broader operating expenses commensurate with our ability to drive top-line revenue growth.

We expect that these actions will allow us to keep the company in a financial position that will enable us to continue to achieve important near-term milestones and execute on our long-term strategy, which remain unchanged.

Overview

We are a commercial-stage biopharmaceutical company that is committed to rewriting treatment for people with cancer through the discovery, development, and commercialization of novel epigenetic medicines. We aspire to change the standard of care for patients and physicians by developing targeted medicines with fundamentally new mechanisms of action directed at specific causes of hematological malignancies and solid tumors.

Our vision is focused on four transformative critical imperatives that we refer to as The Next EPIsode: Rewriting Oncology Treatment with Epigenetics. The four pillars of this five-year corporate strategy are:

Maximize our effectiveness as a commercial organization to achieve adoption of TAZVERIK among as many FL and ES patients as possible, including in earlier treatment lines and in combination regimens with the data to support this expanded use;
Build on TAZVERIK’s pipeline-in-a-drug potential, demonstrating tazemetostat’s benefit in additional hematological malignancies and solid tumors;
Expand our pipeline and evolving oncology portfolio, bringing novel oncology therapeutics into clinical development to maintain our position as a leader in epigenetics; and
Leverage options to expand patient reach and increase shareholder value, including through commercial, clinical, and research collaborations.

34


 

We continue to implement these four pillars as the core of our five-year corporate strategy to promote growth and value creation, and we believe that our streamlined commercial strategy, organizational structure and operational changes will provide the capital flexibility to successfully execute on these pillars.

TAZVERIK Commercialization and Development

Epithelioid Sarcoma

In January 2020, the U.S. Food and Drug Administration, or FDA, granted accelerated approval of TAZVERIK (tazemetostat), an oral, first in class, selective small molecule inhibitor of the EZH2 histone methyltransferase, or HMT, for the treatment of adult and pediatric patients aged 16 years and older with metastatic or locally advanced ES not eligible for complete resection. This approval was based on overall response rate and duration of response shown in the ES cohort of our Phase 2 trial in patients with INI1-negative tumors. We continue to make TAZVERIK available to eligible patients and their physicians in the United States.

EZH-301

As part of the accelerated approval for ES, continued approval for this indication is contingent upon verification and description of clinical benefit in a confirmatory trial. To provide this confirmatory evidence to support a full approval of TAZVERIK for this indication, we are conducting a single global, randomized, controlled Phase 1b/3 confirmatory trial (EZH-301) assessing TAZVERIK in combination with doxorubicin compared with doxorubicin plus placebo as a front-line treatment for ES. The trial is expected to enroll approximately 152 patients. We have completed the planned enrollment in the Phase 1b safety run-in portion of the trial, and we expect to commence the Phase 3 efficacy portion of the trial in 2021. We reported safety and preliminary activity data from the patients in the safety run-in portion of the study at the American Society of Clinical Oncology annual meeting in June 2021.

Follicular Lymphoma

In June 2020, the FDA approved a supplemental New Drug Application, or sNDA, for TAZVERIK for the following FL indications: (1) adult patients with relapsed or refractory FL whose tumors are positive for an EZH2 mutation as detected by an FDA-approved test and who have received at least two prior systemic therapies, and (2) adult patients with relapsed or refractory FL who have no satisfactory alternative treatment options. These indications were approved under accelerated approval with a priority review, based on overall response rate and duration of response data shown in the FL cohorts of our Phase 2 clinical trial in patients with EZH2 mutations and wild-type EZH2. We continue to make TAZVERIK available to eligible patients and their physicians in the United States.

EZH-302 (SYMPHONY-1)

As part of the accelerated approval for FL, continued approval for these indications is contingent upon verification and description of clinical benefit in a confirmatory trial. To provide this confirmatory evidence to support a full approval of TAZVERIK for these indications, we are conducting a single global, randomized, adaptive Phase 1b/3 confirmatory trial (EZH-302, SYMPHONY-1) assessing the combination of tazemetostat with “R2” (lenalidomide and rituximab), an approved chemotherapy-free treatment regimen, compared with R2 plus placebo for FL patients in the second-line or later treatment setting.

During the second quarter of 2021, we completed enrollment of all Phase 1b safety run-in cohorts of SYMPHONY-1 with a total of 36 patients, including patients at the 600mg tazemetostat twice daily dosing regimen and patients at the 800mg tazemetostat twice daily dosing regimen per FDA’s requested number of patients. Through a September 29, 2021 data cutoff date for the Phase 1b safety run-in portion of the trial, the safety profile observed in the patients in both the 800mg and 600mg dose cohorts has been consistent with that described in the respective reference safety information documents in the label. Most notably, no dose-limiting toxicities (DLTs) were reported during the first cycle of treatment. Of the 36 patients enrolled as of the end of the second quarter of 2021, 17 patients were considered evaluable for efficacy based on the availability of tumor scans. All 17 patients responded to treatment, with six patients having a complete response, and 11 patients having a partial response. For all response evaluable patients, the duration on therapy is in the range between 2 and 10 months of therapy. The Phase 1b safety run-in portion of the trial is currently ongoing, and we are following patients to obtain more data following the September 29, 2021 data cut-off date. As we continue to conduct the Phase 1b safety run-in portion of the trial, we are using the time to activate as many study sites as possible, globally, to ensure we can enroll the Phase 3 portion of the trial quickly once we have obtained approval from the FDA. We plan to present further data from the Phase 1b safety run-in portion of the trial at the American Society of Hematology annual meeting in December 2021, which we expect will include data for the approximately 40 patients now enrolled.

We expect that the Phase 3 portion of SYMPHONY-1 will be a global, randomized and adaptive confirmatory trial assessing the combination of tazemetostat with “R2” (lenalidomide and rituximab), an approved chemotherapy-free treatment regimen, compared with R2 plus placebo for FL patients in the second-line or later treatment setting. We expect to conduct this part of the trial in 500 patients globally. The IND that we filed in China for SYMPHONY-1 received China’s Center for Drug Evaluation, or CDE, approval in July 2021, following official CDE acceptance of our IND filing in May 2021. The primary endpoint for the trial will be based on progression free survival as determined by investigator. Based on discussions with the FDA, the trial will include two interim analyses, the first of which is for futility only and second of which will be conducted for futility, and if 65% of progression free survival events have occurred, will also include an efficacy evaluation.

Through our planned development efforts, our intention is to eventually make TAZVERIK available in all lines of treatment for patients with FL. We plan to leverage the confirmatory trial and post-marketing commitments to expand TAZVERIK into the second-line treatment setting. In collaboration with The Lymphoma Study Association, or LYSA, and based on clinical activity observed with tazemetostat in combination with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) as a front-line treatment for patients with high risk diffuse large B-cell lymphoma, or DLBCL, we previously commenced a Phase 2 clinical trial that is being conducted by LYSA evaluating this combination as a front-line treatment for high-risk patients with FL, and is nearing complete enrollment. We also converted an investigator-sponsored study to evaluate tazemetostat in combination with rituximab with FL in the third-line or later treatment settings to a Company-sponsored study in order to expand the number of participating sites, and this Phase 2 study (EZH-1401, SYMPHONY-2) is currently enrolling patients. We expect to share interim data for SYMPHONY-2 at a medical conference in 2022. In addition, we are finalizing plans for investigator-sponsored studies to evaluate tazemetostat in combination with venetoclax or BTK inhibitors for the treatment of patients with FL in the third-line or later treatment settings.

Solid Tumors

We are developing tazemetostat for the treatment of a broad range of cancer types in multiple treatment settings. Tazemetostat has shown meaningful clinical activity as an investigational monotherapy in multiple cancer indications and has been generally well-tolerated across clinical trials to date. We believe tazemetostat is a “pipeline in a product” opportunity and plan to advance life-cycle development for tazemetostat to support its potential utility in additional indications and combinations.

Prostate Cancer

EZH-1101 (CELLO-1)

In connection with these efforts, we are evaluating tazemetostat for the treatment of prostate cancer. We are conducting a global, multi-center, randomized Phase 1b/2 trial (EZH-1101, CELLO-1) evaluating tazemetostat in combination with enzalutamide or abiraterone plus prednisone, the standard of care treatments for metastatic castration-resistant prostate cancer, or mCRPC. As of February 2021, we had completed enrollment in the Phase 1b safety run-in portion of CELLO-1 with a total of 21 men with mCRPC. In September 2021, at the European Society for Medical Oncology (ESMO) Congress, we announced preliminary data from the Phase 1b safety run-in portion of the trial using a data cutoff date of July 22, 2021.

The safety run-in portion of CELLO-1 is being conducted using a standard dose escalation design. Among the 21 patients enrolled in the safety run-in portion, as of the data cutoff date no DLTs were observed at any dose of tazemetostat up to a maximum dose of 1600mg twice daily for patients receiving tazemetostat plus enzalutamide and 800mg twice daily for patients receiving tazemetostat plus abiraterone. As of the July 22, 2021 cutoff date, preliminary data from the trial also showed:

 

36


 

Median progression free survival (PFS) had not been reached at cutoff for the tazemetostat plus enzalutamide arm; six-month PFS was 61.7%.
11 of 21 patients experienced prostate-specific antigen, or PSA, decline from baseline; seven out of 21 patients had a PSA response of ≥50%; one additional patient had a PSA response of ≥30%.
Six of the PSA50 responses were in the tazemetostat + enzalutamide cohort (n=13) and one was in the tazemetostat + abiraterone/prednisone cohort (n=8).
One patient with a PSA50 response achieved a radiographic partial response.
All PSA50 and PSA30 responses were in ARV7 negative and neuroendocrine subtype negative patients identified using the EPIC platform. Only one ARV7 positive patient was enrolled in the safety run-in portion of the trial.

 

Based on early safety and activity findings observed in the Phase 1b safety run-in portion of CELLO-1, in the first quarter of 2021 we initiated enrollment in the Phase 2 efficacy portion of CELLO-1 evaluating tazemetostat in combination with enzalutamide compared to enzalutamide alone, and we expect to include 80 men with mCRPC in this Phase 2 portion of the trial. The primary endpoint for CELLO-1 is radiographic progression free survival. The Phase 2 efficacy portion of CELLO-1 is approximately one-half enrolled.

 

Further Research, Development and Commercialization Efforts and Strategic Collaborations

 

There are four areas where we see the greatest potential for tazemetostat, all of which are based on a strong scientific hypothesis and for diseases that need a new effective and safe treatment option, including:

Lymphomas and B-cell malignancies, such as DLBCL, mantle cell lymphoma, or MCL, multiple myeloma and others;
Molecularly defined solid tumors, such as chordoma, melanoma, mesothelioma, and tumors harboring an EZH2 or SWI/SNF alteration;
PARPi-resistant tumors, such as prostate cancer, small cell lung cancer, and ovarian cancer; and
Immunotherapy resistant tumor settings (primary or acquired), including small cell lung cancer, prostate cancer, and others.

To efficiently evaluate tazemetostat’s potential safety and efficacy across multiple new types of hematological malignancies and solid tumors, we expect to initiate two signal-finding basket studies by the end of 2021. In July 2021, we received “study may proceed” from the FDA with respect to our IND for a proposed solid tumor basket study, and in October 2021, we initiated this basket study, EZH-1301, a Phase 1/1b trial evaluating tazemetostat with multiple combinations across three solid tumor types, and expect to initiate enrollment in this study by the end of 2021. In September 2021, we received “study may proceed” from the FDA with respect to our IND for a proposed hematological malignancies basket study. We expect to initiate enrollment in this study, EZH-1501, a Phase 1/1b trial evaluating tazemetostat with multiple combinations in hematological malignancies by the end of 2021. By furthering these basket studies, we plan to study multiple combinations with standard of care therapies and novel mechanisms of action as we seek to expand the potential of TAZVERIK to patients and the physicians who treat them efficiently and effectively.

TAZVERIK is available to eligible patients in the United States via a specialty distribution network. To commercialize TAZVERIK for the ES and FL indications in the United States, we have built a focused field presence and marketing capabilities. In August 2021, we announced changes to our commercial strategy and organization, including realignment of our commercial organization by creating and expanding new field roles intended to better reach thought leaders and large community accounts, while reducing traditional sales roles and overall headcount. Additionally, we are shifting some of our resources to enhance digital approaches to reach both healthcare providers and patients directly. In June 2021, to help provide access to information that we believe will help evolve the treatment of FL, we launched the EZH2NowSM testing program with Quest Diagnostics to provide EZH2 mutation testing for patients with FL. We believe that these changes will allow us to better deliver on our commercial goals, and we believe that we have made progress against our commercial goals in the third quarter of 2021. Net product revenue for TAZVERIK was $5.2 million in the third quarter of 2021. Net product revenue was $8.0 million in the second quarter of 2021, but included a $3.2 million sale of TAZVERIK in the second quarter of 2021 to a third-party pharmaceutical company for use in its combination clinical trials. Total end user demand for TAZVERIK increased by approximately 22% in the third quarter of 2021 compared to the second quarter of 2021. The amount of free goods supplied to patients via our Patient Assistance Program was approximately 25% of total end user demand for the third quarter of 2021, consistent with the level reported in the second quarter of 2021. We continue to see new prescriptions being written for both EZH2 mutation and wild-type patients, in the academic and community settings and across multiple treatment lines in relapsed or refractory FL patients. Payor coverage for ES and FL continues to be in-line with the TAZVERIK label.

We own the global development and commercialization rights to tazemetostat outside of Japan. Eisai Co. Ltd, or Eisai, holds the rights to develop and commercialize tazemetostat in Japan. On August 7, 2021, pursuant to a license agreement with Hutchison China MediTech Investment Limited, or HutchMed, we granted a license to HutchMed for the co-exclusive (with us) development and exclusive commercialization of tazemetostat, either as a monotherapy or as a part of combinations with other therapies, including HutchMed proprietary compounds, agreed by us and HutchMed for the treatment of epithelioid sarcoma, follicular lymphoma, diffuse large B-cell lymphoma in humans, and any additional indications agreed to by us and HutchMed in mainland China, Taiwan, Hong Kong and Macau, or the HutchMed Territory.

The license agreement with HutchMed, or the HutchMed License Agreement, provides for the development, manufacture and commercialization of tazemetostat in the HutchMed Territory referenced above and is intended to bring TAZVERIK to patients in the HutchMed Territory and to further extend the clinical development of TAZVERIK in new treatment combinations. In September 2021 we received the upfront payment of $25.0 million from HutchMed that was due to us under the HutchMed License Agreement. We are also entitled to milestone payments of up to $110.0 million in the aggregate for achievement of specified development and regulatory milestones with respect to tazemetostat products in the HutchMed Territory under the HutchMed License Agreement, and up to $175.0 million in the aggregate for achievement of specified sales milestones in the HutchMed Territory with respect to tazemetostat products under the HutchMed License Agreement. We will also be entitled to receive tiered royalties, ranging from a mid-teens percentage to a low twenties percentage based on HutchMed’s cumulative annual net sales, if any, of tazemetostat products in the HutchMed Territory.

For other geographies outside the United States, we are evaluating the most efficient path to obtain marketing approval, commercialize and distribute TAZVERIK to reach patients, including pursuing potential strategic collaborations.

In Europe, we are continuing to explore and understand what may be necessary in order for us to submit a marketing authorization application to the European Medicines Agency, or EMA, in an effort to obtain marketing approval of tazemetostat from the EMA in ES and FL. We expect to define a path to regulatory submission in Europe by the end of 2021.

Tazemetostat is covered by claims of U.S. and European composition of matter patents, which are expected to expire in 2032, exclusive of any patent term or other extensions. Tazemetostat has been granted Fast Track designation by the FDA in patients with relapsed or refractory FL, relapsed or refractory DLBCL with EZH2 activating mutations and metastatic or locally advanced ES who have progressed on or following an anthracycline-based treatment regimen. The FDA has also granted orphan drug designation to tazemetostat for the treatment of patients with malignant rhabdoid tumors, or MRT, soft tissue sarcoma, and mesothelioma, and a seven-year orphan drug exclusivity period from the dates of our respective approvals of TAZVERIK for the treatment of patients with ES and for the treatment of patients with FL.

Beyond tazemetostat, we are utilizing our drug discovery platform to progress preclinical efforts and discover and identify additional product candidates to expand our pipeline of inhibitors against several classes of chromatin modifying proteins, or CMPs, including HMTs, histone acetyltransferases, or HATs, and helicases.

 

EZM0414 (SETD2)

The most advanced of these product candidates is a novel first-in-class oral inhibitor of SETD2 (EZM0414). SETD2 is an HMT, similar to EZH2, which plays multiple important roles in oncogenesis. Based on the potential of SETD2 inhibition demonstrated in multiple preclinical settings, including multiple myeloma, and in particular high risk t(4;14) multiple myeloma and in other B-cell malignancies such as diffuse large B-cell lymphoma, as well as in combination with existing and emerging therapies including tazemetostat, we submitted an IND for EZM0414 to the FDA in July 2021. We received “study may proceed” from the FDA with respect to our IND for EZM0414 in July 2021 and have initiated the first-in-human study and plan to enroll the first patient in the study by the end of 2021. This study is intended to evaluate the safety and optimize the dose and schedule of EZM0414 in relapsed or refractory multiple myeloma and DLBCL patients. Once we have optimized the dose, we then expect to further expand to three patient cohorts: t(4;14) multiple myeloma, non t(4;14) multiple myeloma and DLBCL. In October 2021, EZM0414 was granted Fast Track designation by the FDA in adult patients with relapsed or refractory DLBCL.

Strategic Collaborations

To date, we have entered into various strategic collaborations, including with HutchMed, Glaxo Group Limited (an affiliate of GlaxoSmithKline plc), or GSK, Eisai, Roche and other third parties. As one of several key aspects of our strategy, we plan to continue to leverage our existing collaborations and to seek to identify new strategic collaborations to further support and grow our business in and outside of the United States. See Note 12, Collaborations and Licensing Agreements, of the notes to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for a description of the key terms of our collaborations.

Finance Overview

Through September 30, 2021, in addition to revenues from product sales, we have raised an aggregate of $1,560.6 million to fund our operations. This includes $268.8 million of non-equity funding through our collaboration agreements, $368.1 million of funding, consisting of $150.0 million in equity funding received through agreements with RPI Finance Trust, or RPI, and $218.1 million in debt financing received through an amended and restated loan agreement, or the Amended and Restated Loan Agreement, with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership (as transferee of BioPharma Credit Investments V (Master) LP’s interest as a lender), or the Lenders, $847.7 million from the sale of common stock and series A convertible preferred stock in our public offerings and at-the-market offerings and $76.0 million from the sale of redeemable convertible preferred stock in private financings prior to our initial public offering in May 2013.

As of September 30, 2021, we had $221.3 million in cash, cash equivalents and marketable securities.

We commenced active operations in early 2008, and since inception, have incurred significant operating losses. Our net loss was $65.8 million and $200.5 million for the three and nine months ended September 30, 2021, respectively. As of September 30, 2021, our accumulated deficit totaled $1,189.2 million. Notwithstanding our sales of TAZVERIK, we expect to continue to incur significant expenses and operating losses over the next several years. Our expenses and net losses may fluctuate significantly from quarter to quarter and year to year as we continue to fund our most important value-driving clinical trials and programs; implement and execute changes to our commercial strategy; make any royalty payments provided for and achieved under the amended and restated collaboration and license agreement with Eisai; pay interest and principal associated with the Amended and Restated Loan Agreement; and continue research and development and initiate clinical trials of, and seek regulatory approval for, any future product candidates.

 

Funding Agreements with BioPharma Credit Investments V (Master) LP, BPCR Limited Partnership, BioPharma Credit PLC and RPI Finance Trust

We executed a purchase agreement with RPI on November 4, 2019, or the RPI Purchase Agreement. Pursuant to the RPI Purchase Agreement, we sold to RPI 6,666,667 shares of our common stock and a warrant to purchase up to 2,500,000 shares of our common stock at an exercise price of $20.00 per share, or the Common Stock Warrant. We also sold our rights to receive royalties from Eisai with respect to net sales by Eisai of tazemetostat products in Japan, or the Japan Royalty, pursuant to the amended and restated collaboration and license agreement between us and Eisai, dated as of March 12, 2015, or the Eisai License Agreement. In consideration for the sale of shares of our common stock, the Common Stock Warrant and the Japan Royalty, RPI paid us $100.0 million upon the closing of the RPI Purchase Agreement in November 2019. In addition, RPI agreed, in connection with RPI’s acquisition from Eisai of the right to receive royalties from us under the Eisai License Agreement, to reduce our royalty obligation by low single digits upon the achievement of specified annual net sales levels. We also had the option to sell to RPI $50.0 million of shares of common stock for an 18-month period beginning November 4, 2019, or the Put Option. On February 11, 2020, we sold 2,500,000 shares of common stock to RPI for an aggregate of $50.0 million in proceeds at a sale price of $20.00 per share of common stock pursuant to the Put Option.

 

On November 4, 2019, we also entered into a Loan Agreement with BioPharma Credit PLC, or the Collateral Agent, and the Lenders, providing for up to $70.0 million in secured term loans to be advanced in up to three tranches, or the Loan Agreement. We borrowed $70.0 million in the aggregate under the three tranches pursuant to the Loan Agreement.

On November 3, 2020, we, the Collateral Agent and the Lenders amended and restated the Loan Agreement, or, as amended and restated, the Amended and Restated Loan Agreement. The Amended and Restated Loan Agreement provides for, among other things, an additional secured term loan facility of $150.0 million, or the Tranche D Loan. On November 18, 2020, we borrowed the Tranche D Loan.

 

Under the Amended and Restated Loan Agreement, we have the right to request from the Lenders, subject to the Lenders’ agreement to lend additional amounts to us, up to an additional $150.0 million, provided that we have not prepaid any outstanding term loans at the time of our request and such request is made before November 18, 2021.

The obligations under the Amended and Restated Loan Agreement remain secured by a first priority security interest that was granted at the time of the Loan Agreement in and a lien on substantially all of our assets, subject to certain exceptions.

The Amended and Restated Loan Agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default applicable to us and our subsidiaries. If an event of default occurs and is continuing, the Collateral Agent under the Amended and Restated Loan Agreement may, among other things, accelerate the loans and foreclose on the

Product Revenues, net

Net product revenues represent U.S. sales from our sole commercial product, TAZVERIK, which was first approved by the FDA on January 23, 2020, less allowances and accruals. During the three months ended September 30, 2021 and 2020, net product revenues were $5.2 million and $3.4 million, respectively. The $1.8 million increase reflects the timing of approval of TAZVERIK for ES in January 2020 and the approval of TAZVERIK for FL in June 2020. During the nine months ended September 30, 2021 and 2020, net product revenues were $19.4 million and $7.0 million, respectively. The $12.4 million increase reflects the timing of approval of TAZVERIK for ES in January 2020 and the approval of TAZVERIK for FL in June 2020. The increase also reflects the inclusion in product revenue during the 2021 period of $3.2 million related to the sale of commercial product by one of our customers to a third-party pharmaceutical company for use in its clinical trials. Sales allowances and accruals consisted of patient financial assistance, distribution fees, discounts, and chargebacks.

 

Collaboration and Other Revenue

Our collaboration and other revenue during the periods included amounts recognized from deferred revenue related to upfront payments for licenses or options to obtain licenses in the future, research and development services revenue earned, milestone payments earned under collaboration and license agreements with our collaboration partners and revenue from the sale of tazemetostat active pharmaceutical ingredient (API) and drug product to our licensees or collaborators.

In the three and nine months ended September 30, 2021, we recognized $0.0 and $6.5 million, respectively, in collaboration and other revenue. This collaboration revenue was recognized as part of our supply agreement with Eisai for the Company’s waiver of its exclusive right to its manufacturer for the supply of tazemetostat drug substance, the manufacture and supply of tazemetostat and technical support services. In the three and nine months ended September 30, 2020, we recognized $0.1 million and $0.4 million in collaboration revenue as part of our Boehringer Ingelheim collaboration. We recognized revenue as our research services were performed. In December 2020, we received written notice from Boehringer Ingelheim to terminate the collaboration agreement, effective January 31, 2021.

royalties payable on net sales of TAZVERIK. During the three months ended September 30, 2021 and 2020, the cost of product revenue was $2.0 million and $1.6 million, respectively, and consisted of $0.2 million and $0.1 million, respectively, in costs associated with manufacturing TAZVERIK, $1.0 million and $1.0 million, respectively, in amortization expense related to the two $25.0 million milestone payments we paid under our agreement with Eisai upon regulatory approval of TAZVERIK for epithelioid sarcoma and upon regulatory approval of TAZVERIK for follicular lymphoma, and $0.8 million and $0.5 million, respectively, in worldwide royalties due under the Eisai License Agreement on net sales of TAZVERIK. We did not have cost of other revenues in the three months ended September 30, 2021.

 

During the nine months ended September 30, 2021 and 2020, the cost of product revenue was $7.3 million and $3.2 million, respectively, and consisted of $0.5 million and $0.2 million, respectively, in costs associated with manufacturing TAZVERIK, $3.1 million and $2.0 million, respectively, in amortization expense related to the $25.0 million milestone payment we paid under our agreement with Eisai upon regulatory approval of tazemetostat for epithelioid sarcoma, and $2.9 million and $1.0 million, respectively, in worldwide royalties due under the Eisai License Agreement on net sales of TAZVERIK. Cost of other revenue during the nine months ended September 30, 2021 consisted of $0.8 million of costs related to sales of tazemetostat drug product to Eisai. All product costs incurred prior to FDA approval of TAZVERIK in January 2020 were expensed as research and development expenses. We expect our cost of product revenues to continue to be positively impacted during 2021 and in future periods, as we sell through certain inventory that was expensed prior to FDA approval of TAZVERIK in January 2020.

Research and Development

Research and development expenses consist of expenses incurred in performing research and development activities, including clinical trials and related clinical manufacturing expenses, fees paid to external providers of research and development services, third-party clinical research organizations, or CROs, compensation and benefits for full-time research and development employees, facilities expenses, overhead expenses, and other outside expenses. Most of our research and development costs are external costs, which we track on a program-by-program basis. Our internal research and development costs are primarily compensation expenses for our full-time research and development employees, including stock-based compensation expense.

External research and development costs include external manufacturing costs related to the acquisition of active pharmaceutical ingredient and manufacturing of clinical drug supply, ongoing clinical trial costs, discovery and preclinical research in support of the tazemetostat program and expenses associated with our companion diagnostic program.

 

External research and development expenses for tazemetostat and related EZH2 programs increased $5.9 million and $14.2 million, respectively, for the three and nine months ended September 30, 2021 compared to the three and nine months ended September 30, 2020. The increase for the three and nine months ended September 30, 2021 relates to increases in clinical trial expenses and discovery research activities related to tazemetostat in other indications, which were offset by decreases in costs associated with the build-out of our regulatory and late-stage development groups that we conducted in 2020.

 

External research and development expenses for our SETD2 inhibitor EZM0414 program increased $1.3 million for the three and nine months ended September 30, 2021 compared to the three and nine months ended September 30, 2020. The increase is due to the designation of the program as a clinical development program in the third quarter of 2021.

 

External research and development expenses for discovery and preclinical stage product programs decreased by $0.5 million for the three months ended September 30, 2021 compared to the three months ended September 30, 2020, and increased $4.5 million for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The decrease in the three months ended September 30, 2021 is primarily related to the movement of the SETD2 inhibitor EZM0414 program out of discovery and preclinical stage product programs during the third quarter of 2021 while the increase in the nine months ended September 30, 2021 was primarily related to increased spending for discovery research activities and development activities related to our preclinical programs, partially offset by the movement of the SETD2 inhibitor EZM0414 program out of discovery and preclinical stage product programs.

Unallocated personnel and other expenses are comprised of compensation expenses for our full-time research and development employees and other general research and development expenses. Unallocated personnel and other expenses during the three and nine months ended September 30, 2021 increased $2.1 million and $4.8 million, respectively, compared to the three and nine months ended September 30, 2020. The increase is a result of increases in facilities and equipment related expenses and in unallocated personnel costs, offset by an increase in the allocation of expenses to projects.

We expect that research and development expenses will decrease through the fourth quarter of 2021, as we continue to implement our operating expense reductions and prioritize our investment of company resources in what we believe to be our most important value-driving clinical trials and programs, including our EZH-302, EZH-1401 and EZH-1101 trials, our two basket studies and our EZM0414 program.

Selling, General and Administrative

Selling, general and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation, related to our executive, finance, intellectual property, business development and support functions. Other selling, general and administrative expenses include allocated facility-related costs not otherwise included in research and development expenses, travel expenses and professional fees for auditing, tax and legal services, including intellectual property and general legal services.

For the three and nine months ended September 30, 2021, our selling, general and administrative expenses increased $2.2 million and $12.9 million, respectively, compared to the three and nine months ended September 30, 2020. The increase for the three and nine months ended September 30, 2021 compared to the three and nine months ended September 30, 2020 is due to increased commercialization activities, including the build-out of our sales force and commercial infrastructure to support the commercial launch of TAZVERIK in the approved ES and FL indications in 2020, and increased personnel related expenses. Additionally, severance and termination-related costs totaling $1.6 million were recorded in the three months ended September 30, 2021 related to the August 2021 cost reduction plan.

42


 

We expect that selling, general and administrative expenses will decrease through the fourth quarter of 2021, as we implement changes to our commercial strategy and organization in an effort to accelerate commercial adoption of TAZVERIK in appropriate patients as well as an operational cost reduction across general and administrative functions as part of our prioritization of our investment of company resources in what we believe to be our most important value-driving clinical trials and programs.

Other (expense) income, net consists of interest income earned on our cash equivalents and marketable securities, interest expense related to our long-term debt obligations, non-cash changes in the fair value of warrant liabilities and non-cash interest expense related to the sale of future royalties. There was no change in other expense for the three months ended September 30, 2021 is principally due to an increase in interest expense of $3.8 million incurred in connection with our long-term debt obligations under our Amended and Restated Loan Agreement, an increase in non-cash interest expense related to the sale of future royalties of $0.1 million and income related to the changes in fair value of warrant liability of $4.4 million. The increase in other expense for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 is principally due to an increase in interest expense of $13.0 million incurred in connection with our long-term debt obligations under our Amended and Restated Loan Agreement, and an increase in non-cash interest expense related to the sale of future royalties of $0.5 million and income related to the changes in fair value of warrant liability of $4.4 million.

 

Income Tax Expense

We did not record a federal or state income tax provision or benefit for the three and nine months ended September 30, 2021 and 2020 due to the expected and known loss before income taxes to be incurred, or incurred, as applicable, for the years ended December 31, 2021 and 2020, as well as our continued maintenance of a full valuation allowance against our net deferred tax assets, with the exception of the deferred tax asset related to alternative minimum tax credit.

Liquidity and Capital Resources

Through September 30, 2021, in addition to revenues from product sales, we have raised an aggregate of $1,560.6 million to fund our operations. This includes $268.8 million of non-equity funding through our collaboration agreements, including the $25.0 million upfront payment received from HutchMed in September 2021, $368.1 million of funding, consisting of $150.0 million in equity funding received through agreements with RPI Finance Trust, or RPI, and $218.1 million in debt financing received through a loan agreement with BioPharma Credit Investments V (Master) LP and BPCR Limited Partnership (as transferee of BioPharma Credit Investments V (Master) LP’s interest as a lender), $847.7 million from the sale of common stock and series A convertible preferred stock in our public offerings and at-the-market offerings and $76.0 million from the sale of redeemable convertible preferred stock in private financings prior to our initial public offering in May 2013. As of September 30, 2021, we had $221.3 million in cash, cash equivalents and marketable securities.

On May 6, 2021, we entered into an Open Market Sale AgreementSM, or ATM Sale Agreement, with Jefferies LLC, or Jefferies, to sell, from time to time, shares of our common stock having an aggregate offering price of up to $200,000,000 through an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended, under which Jefferies would act as sales agent, which we refer to as the ATM Offering. The shares that may be sold under the ATM Sale Agreement, if any, are issued and sold pursuant to the Company’s shelf registration statement on Form S-3 that was declared effective by the Securities and Exchange Commission on May 13, 2021. Through September 30, 2021, we have sold a total of 1,430,465 shares of our common stock under the

43


 

ATM Offering resulting in net proceeds of approximately $8.3 million. Subsequent to September 30, 2021, we have sold 229,150 shares of our common stock under the ATM Offering resulting in net proceeds of approximately $1.1 million.

In November 2019, we raised approximately $123.1 million in net proceeds from the sale to RPI of 6,666,667 shares of our common stock, the Warrant and the Japan Royalty for, as well as from proceeds of the Tranche A Loan borrowings under the Loan Agreement. On February 11, 2020, we sold 2,500,000 shares of common stock to RPI for an aggregate of $50.0 million in proceeds at a sale price of $20.00 per share of common stock pursuant to the Put Option. On March 27, 2020, we received proceeds of the Tranche B Loan borrowings of $25.0 million under the Loan Agreement. On June 30, 2020, we received proceeds of the Tranche C Loan borrowings of $20.0 million under the Loan Agreement. On November 18, 2020 we received proceeds of the Tranche D Loan borrowings of $150.0 million under the Amended and Restated Loan Agreement.

In addition to our existing cash, cash equivalents and marketable securities, we are eligible to earn a significant amount of milestone payments under our collaboration agreements with HutchMed and GSK. Our ability to earn these payments and the timing of earning these payments is dependent upon the outcome of our research and development activities and is uncertain at this time.

Funding Requirements

Our primary uses of capital are clinical trial costs, third-party research and development services, expenses related to commercialization, debt service obligations, compensation and related expenses, laboratory and related supplies, legal and other regulatory expenses and general overhead costs.

Because the continued approval of TAZVERIK in the approved indications is contingent upon verification and description of clinical benefit in confirmatory trials, and because we are developing tazemetostat for other indications, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of TAZVERIK for the indications that we are exploring or that we may plan to explore. Because any future product candidates are in various stages of preclinical development with uncertain outcomes, we also cannot estimate the actual amounts necessary to successfully complete the development and commercialization of future product candidates. Because of these uncertainties, we also cannot estimate whether, or when, we may achieve profitability. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity or debt financings and collaboration arrangements. Except for any obligations of our collaborators to make license, milestone or royalty payments under our agreements with them, we do not have any committed external sources of liquidity. To the extent that we raise additional capital through the future sale of equity or debt, the ownership interest of our stockholders may be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration arrangements in the future, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise any additional funds that may be needed through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Outlook

Based on our current operating plan which includes the anticipated savings resulting from the cost reduction plan we announced in August 2021, we expect that our existing cash, cash equivalents and marketable securities as of September 30, 2021, will be sufficient to fund our planned operating expenses and capital expenditure requirements and pay our debt service obligations as they become due into the fourth quarter of 2022, which is at least 12 months from the date of this report, without giving effect to any potential future milestone payments we may receive under our collaboration agreements with HutchMed or GSK. We have based this estimate on assumptions that may prove to be wrong, such as the revenue that we expect to generate from the sale of our products, and particularly as the process of testing drug candidates in clinical trials is costly and the timing of progress in these trials is uncertain. As a result, we could use our capital resources sooner than we expect.

Net Cash Used in Operating Activities

Net cash used in operating activities was $174.9 million during the nine months ended September 30, 2021 compared to $153.2 million during the nine months ended September 30, 2020. The increase in net cash used in operating activities primarily relates to our net loss of $200.5 million and the $4.4 million change in fair value of warrants, partially offset by changes in working capital of $3.3 million, net depreciation and amortization of $5.4 million, non-cash stock-based compensation of $19.9 million, and non-cash interest expense associated with the sale of future royalties of $1.4 million.

Net cash used in operating activities during the nine months ended September 30, 2020 primarily relates to our net loss of $165.5 million, changes in working capital of $12.5 million, partially offset by net depreciation and amortization of $2.7 million, non-cash stock-based compensation of $21.2 million, and non-cash interest expense associated with the sale of future royalties of $0.9 million.

Net Cash Provided by Investing Activities

Net cash used in investing activities during the nine months ended September 30, 2021 reflects maturities of available-for-sale securities of $311.6 million, offset by $203.9 million of purchases of available-for-sale securities, and $0.4 million of purchases of property and equipment.

Net cash provided by investing activities during the nine months ended September 30, 2020 reflects maturities of available-for-sale securities of $212.4 million, offset by $156.9 million of purchases of available-for-sale securities, $25.0 million milestone payment under the Eisai collaboration agreement upon regulatory approval of tazemetostat for ES, a $25.0 million milestone payment under the Eisai collaboration agreement upon regulatory approval of tazemetostat for FL, and $0.6 million of purchases of property and equipment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities of $23.9 million during the nine months ended September 30, 2021 primarily reflects net proceeds from the sale of common stock under the ATM Sale Agreement of $8.3 million, the purchases of shares under our employee stock purchase plan of $1.9 million, stock option exercises of $0.9 million, and $13.1 million from the issuance of the HutchMed Warrant, partially offset by the payment of offering costs of $0.2 million related to the ATM program.

Net cash provided by financing activities of $102.3 million during the nine months ended September 30, 2020 primarily reflects cash received from the sale of common stock of $50.0 million in connection with our exercise of our Put Option to sell shares of our common stock to RPI, net cash received during the period from Tranche B Loan borrowings of $25.0 million under the Loan Agreement, net cash received during the period from Tranche C Loan borrowings of $20.0 million under the Loan Agreement, stock option exercises of $6.3 million, and the purchases of shares under our employee stock purchase plan of $1.3 million, partially offset by payments of debt issuance costs of $0.1 million and offering costs of $0.1 million.

On August 11, 2021, we entered into a fifth amendment to the Technology Square Lease (the “Fifth Amendment”) with ARE-TECH Square, LLC. Under the Fifth Amendment, we extended the term of the Technology Square Lease through November 30, 2024. Under the Fifth Amendment, we will continue to pay the Landlord the current monthly base rent amount contemplated by the Technology Square Lease through November 30, 2022, with an increase commencing on December 1, 2022 and adjusting the monthly base rent amount to approximately $377,000 and an increase commencing on December 1, 2023 and adjusting the monthly base rent amount to approximately $388,000 through November 30, 2024. Under the current terms of the Technology Square Lease, we do not have any further right to extend the term beyond November 30, 2024.

There were no other material changes to our contractual obligations and commitments described under “Management’s Discussion and Analysis and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of our consolidated balance sheets and the reported amounts of collaboration revenue, inventories and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances at the time such estimates are made. Actual results and outcomes may differ materially from our estimates, judgments and assumptions. We periodically review our estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in the condensed consolidated financial statements prospectively from the date of the change in estimate.

We define our critical accounting policies as those accounting principles generally accepted in the United States of America that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations as well as the specific manner in which we apply those principles. Management has determined that our most critical accounting policies are those relating to revenue recognition, inventories, stock-based compensation and research and development expenses, including our accounting for clinical trial expenses and accruals. As our clinical development plan for tazemetostat progresses, we expect research and development expenses and, in particular, our accounting for clinical trial accruals to be an increasingly important critical accounting policy.

Except as described below with respect to intangible assets, net, during the nine months ended September 30, 2021, there have been no material changes with respect to our critical accounting policies disclosed in our Annual Report on Form 10-K for our fiscal year ended December 31, 2020.

 

Intangible Assets, Net

Intangible assets consist of capitalized milestone payments made to third parties under an in-license of patent rights upon receiving regulatory approval of TAZVERIK. The finite-lived intangible assets are being amortized on a straight-line basis over the expected time period we will benefit from the in-licensed rights, which is generally the patent life. Intangible assets are recorded at cost at the time of their acquisition and are stated in our condensed consolidated balance sheets net of accumulated amortization and impairments, if applicable. The amortization expense is recognized as cost of product revenue in our condensed consolidated statement of operations and comprehensive loss.

We assess our intangible assets for impairment if indicators are present or changes in circumstance suggest that impairment may exist. Events that could result in an impairment, or trigger an interim impairment assessment, include the receipt of additional clinical or nonclinical data regarding one of our drug candidates or a potentially competitive drug candidate, changes in the clinical development program for a drug candidate, or new information regarding potential sales for the drug. If impairment indicators are present or changes in circumstance suggest that impairment may exist, we perform a recoverability test by comparing the sum of the estimated undiscounted cash flows of each intangible asset to its carrying value on our condensed consolidated balance sheet. If the

46


 

undiscounted cash flows used in the recoverability test are less than the carrying value, we would determine the fair value of the intangible asset and recognize an impairment loss if the carrying value of the intangible asset exceeds its fair value.

Our assessment of the recoverability of our intangible assets requires the use of estimates, in particular the estimated future revenues to be generated from the intangible asset, as well as the direct costs associated with the revenues. Due to our limited history of sales and the inherent difficulty in making a long-range forecast, such estimates contain significant uncertainty. If the assumptions regarding forecasted revenue or the costs to derive such revenues are not achieved, we may be required to perform future impairment analyses and record an impairment charge for the intangible asset in future periods.

Recently Adopted Accounting Pronouncements

For detailed information regarding recently issued accounting pronouncements and the expected impact on our condensed consolidated financial statements, see Note 2, Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements, in the accompanying Notes to Condensed Consolidated Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q.

47


 

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates. As of September 30, 2021, we had cash and cash equivalents and marketable securities of $221.3 million, consisting of money market funds, corporate bonds, commercial paper and government-related obligations. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. We estimate that a hypothetical 100-basis point change in market interest rates would impact the fair value of our investment portfolio as of September 30, 2021 by $0.1 million.

We contract with contract research organizations and manufacturers globally. Transactions with these providers are predominantly settled in U.S. dollars and, therefore, we believe that we have only minimal exposure to foreign currency exchange risks. We do not hedge against foreign currency risks.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to management, including the principal executive officer and the principal financial officer, to allow timely decisions regarding required disclosure.

Our management, under the supervision and with the participation of the principal executive officer (our President and Chief Executive Officer) and the principal financial officer (our President and Chief Executive Officer), has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives. Our disclosure controls and procedures have been designed to provide reasonable assurance of achieving their objectives. Based on such evaluation, our President and Chief Executive Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2021.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1A. Risk Factors

The following information updates, and should be read in conjunction with, the risk factors discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, or the 2020 10-K. Any of the risk factors contained in the 2020 10-K and in this Quarterly Report on Form 10-Q could materially affect our business, financial condition or future results, and such risk factors may not be the only risks we face. The COVID-19 pandemic has heightened, and in some cases manifested, certain of the risks we normally face in operating our business, including those disclosed in the 2020 10-K, and the risk factor disclosure in the 2020 10-K is qualified by the information relating to COVID-19 that is described in this Quarterly Report on Form 10-Q. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Our changes to our commercial strategy and organization, adjustments to our operating plans, including operating expense reductions, and leadership transitions may not be successful, may not result in accelerated commercial adoption of TAZVERIK and greater product revenues or anticipated savings, could result in total costs and expenses that are greater than expected and could disrupt our business.

In August 2021, we announced changes to our leadership team with the resignation of our President and Chief Executive Officer, Robert Bazemore, and the appointment of Grant Bogle, a member of our board of directors since September 2019, as President and Chief Executive Officer, each effective as of August 9, 2021. In addition, in August 2021, we made the decision to eliminate the Chief Commercial Officer position, effective at the end of October 2021, and in October 2021 we announced the elimination of the role and departure of our now-former Executive Vice President, Chief Strategy and Business Officer.

In addition, in August 2021, we announced changes to our commercial strategy and organization in an effort to accelerate commercial adoption of TAZVERIK as well as a broader operational cost reduction plan. As part of our cost reduction plan, we implemented a cross-functional reduction of approximately 11% of our then-current workforce. We continue to implement our broader operational cost reduction plan efforts, and we plan to continue to monitor and further reduce our operating expenses in the fourth quarter of 2021 and through our 2022 budgeting process.

We may not realize, in full or in part, the anticipated benefits, savings and improvements from these changes or from any future changes we may decide to make. For instance, the changes to our commercial strategy and organization may not result in accelerated commercial adoption of TAZVERIK or greater product revenues. We believe that the commercial launch has been adversely affected by the COVID-19 pandemic and may continue to be adversely affected by the pandemic. In addition, market acceptance of TAZVERIK and product revenues have been adversely impacted by other factors, including competitive therapies and the use of our patient assistance program, which our changes may not address. The reduction in the size of our field organization and the departure of our Chief Commercial Officer may also limit the success of our refined strategy.

Our organizational changes, operating plan adjustments and operating expense reductions also may not be successful. If we are unable to realize the expected operational efficiencies and cost savings from these changes, our operating results and financial condition would be adversely affected. We also cannot ensure that we will not have to undertake additional workforce reductions or other cost-cutting measures in the future. Furthermore, these changes as well as the leadership transitions may be disruptive to our operations. For example, our workforce reductions and leadership changes could yield unanticipated consequences, such as attrition beyond planned staff reductions and negative impact on employee morale or could make it more difficult to fulfill our day-to-day operations. Our workforce reductions and leadership changes could also harm our ability to attract and retain qualified management, scientific, clinical, manufacturing and sales and marketing personnel who are critical to our business. Year to date, our annualized turnover rate is higher than in prior years and these changes could further that trend. Any failure to attract or retain qualified personnel could prevent us from successfully commercializing TAZVERIK and discovering and developing any other future products or product candidates in the future.

We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than we do.

The development and commercialization of new drug products is highly competitive. We face competition with respect to tazemetostat, and will likely face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of products for the treatment of many of the indications for which we are selling TAZVERIK and for which we are developing tazemetostat. Some of these competitive products and therapies are based on scientific approaches that are the same as or

49


 

similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization of pharmaceutical products that may compete with our products or product candidates. Tazemetostat and any future product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.

In the relapsed and refractory FL patient setting, both current and near-term competition exists. The most common current treatments for FL are chemotherapies, usually combined with the CD-20 antibodies Rituxan or Gayda. Multiple PI3K therapies, such as idelalisib (ZYDELIG), copanlisib (ALIQOPA), duvelisib (COPIKTRA), and umbralisib (UKONIQ) are approved for patients with relapsed/refractory FL. Parsaclisib is currently undergoing standard review by the FDA for approval in FL patients that are refractory to treatment or relapse after two prior lines. These therapies are utilized predominantly in the third line or later treatment. While CD20 and PI3K therapies are approved in FL, there are no therapies that are approved specifically for the treatment of tumors associated with EZH2 activating mutations. There are a number of companies currently evaluating investigational agents in the relapsed and refractory follicular lymphoma patient setting including the development of CAR-T therapies and bispecific monoclonal antibodies. In the first quarter of 2021, Kite Pharma, a subsidiary of Gilead Sciences, received FDA approval for its CAR-T therapy, YESCARTA, for the treatment of relapsed or refractory FL patients. Novartis is also developing its CAR-T therapy, KYMRIAH, for relapsed or refractory FL patients with plans to submit an NDA for approval in this population by the end of 2021. Novartis is also developing its CAR-T therapy, KYMRIAH, for relapsed or refractory FL patients and is undergoing priority review by the FDA. The bispecific antibody furthest along in development in relapsed or refractory FL is Roche’s CD3/CD20 bispecific mosunetuzumab.

In the ES patient setting, there are no therapies approved specifically for epithelioid sarcoma, other than TAZVERIK. Most of the approved therapies utilized in ES are more broadly approved for soft tissue sarcoma in general. Furthermore, the only therapies in late stage clinical trials are being developed broadly for the treatment of soft tissue sarcoma as well.

There are a large number of companies developing or marketing treatments for cancer, including many major pharmaceutical and biotechnology companies. Companies that are developing new epigenetic treatments for cancer that target histone methyltransferases, or HMTs, and protein arginine methyltransferases, or PRMTs, include GSK, Johnson & Johnson, Pfizer, Inc., Daiichi Sankyo Company Limited, and Constellation Pharmaceuticals. Further, companies which are known to have EZH2 inhibitor programs or related programs include: Constellation Pharmaceuticals, developing an EZH2 inhibitor (CPI-0209, Phase 1/2 for advanced tumors (solid tumors and diffuse large B-cell lymphoma, or DLBCL)); Novartis AG, developing an EED inhibitor which indirectly blocks EZH2 (MAK683, Phase 1/2 for advanced malignancies (DLBCL)); Daiichi Sankyo, developing a EZH1/EZH2 dual inhibitor (valemetostat, DS-3201, Phase 1 for relapsed or refractory non-Hodgkin lymphomas, as well as Phase 2 for small cell lung cancer and relapsed or refractory adult T-cell leukemia/lymphoma); Pfizer, developing an EZH2 inhibitor (PF-06821497, Phase 1 for relapsed or refractory small cell lung cancer, castration-resistant prostate cancer and FL); and Jiangsu Hengrui Pharmaceutical, developing an EZH2 inhibitor (SHR2554, Phase 2 for B-cell malignancies) in China. In addition, many companies are developing cancer therapeutics that work by targeting epigenetic mechanisms other than HMTs, including Celgene Corporation (now part of Bristol-Myers Squibb), or Celgene, Merck & Co., Inc., Secura Bio, Spectrum Pharmaceuticals, and Otsuka Pharmaceuticals Co., Ltd., which are marketing cancer treatments that work by targeting epigenetic mechanisms other than HMTs.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than tazemetostat for ES, FL or any indication for which we may develop tazemetostat or any other products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for tazemetostat for any future indication for which we may develop tazemetostat or any other product we may develop, which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. Generic products are currently on the market for many of the indications that we are pursuing, and additional products are expected to become available on a generic basis over the coming years. We expect that tazemetostat will continue to be priced at a significant premium over competitive generic products.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

The COVID-19 pandemic has impacted our commercial launch of TAZVERIK in FL and ES, may affect our ability to initiate and complete preclinical studies and our ongoing and planned clinical trials, disrupt regulatory activities, further disrupt commercialization of TAZVERIK, or have other adverse effects on our business and operations. In addition, the COVID-19 pandemic has caused substantial disruption in the global financial markets, global supply chains and may adversely impact economies worldwide, which could result in adverse effects on our business and operations.

The COVID-19 pandemic, which began in late 2019 and has spread worldwide, is causing many governments to implement measures intended to slow the spread of the outbreak through quarantines, travel restrictions, heightened border scrutiny, and other measures. The outbreak and government measures taken in response have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities have been disrupted and production has been suspended; unemployment has increased; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen. The future progression of the outbreak and its effects on our business and operations are uncertain.

We and our contract manufacturing organizations, or CMOs, and contract research organizations, or CROs, may face disruptions that could affect our ability to initiate and conduct preclinical studies and our planned and ongoing clinical trials, including disruptions in procuring items that are essential for our research and development activities, such as access to raw materials used in the manufacture of tazemetostat and/or our other future product candidates, laboratory supplies used in our preclinical studies and ongoing clinical trials, or animals that are used for preclinical testing for which there are shortages because of ongoing efforts to address the outbreak, and resulting disruptions to many global supply chains. We and our CROs and CMOs, as well as clinical trial sites, may face disruptions related to the conduct of our ongoing clinical trials, planned clinical trials or future clinical trials arising from manufacturing disruptions, staffing disruptions and limitations in regard to our internal activities and the activities of our CROs and CMOs, and delays in the ability to obtain necessary institutional review board or other necessary site approvals or delays in site initiations or site monitoring visits, as well as other delays at clinical trial sites. We may also face limitations on enrollment and patients withdrawing from our clinical trials or not complying with the protocol procedures, which could delay completion of our clinical trials or adversely affect the data generated by such trials. The response to the COVID-19 pandemic may also redirect resources with respect to regulatory and intellectual property matters in a way that could adversely impact our ability to progress regulatory approvals and protect our intellectual property. In addition, we may face impediments to regulatory meetings and approvals due to measures intended to limit in-person interactions.

We commenced commercial sales of TAZVERIK in January 2020, and the pandemic and related government-imposed measures have limited our ability to readily access accounts and healthcare professionals, in person or at all, and to provide medical information in support of TAZVERIK utilization. For example, during the first and second quarters of 2021, the COVID-19 pandemic continued to negatively impact ES and FL patient visits to physicians and subsequent new patient starts across all lines of treatment, as well as the ability of our field-based teams to fully access ES and FL prescribers, and these challenges continued through the third quarter of 2021. We expect that some of these challenges posed by some of the changes brought about by the COVID-19 pandemic, such as ongoing restrictions to access providers by traditional sales personnel, will likely persist even after the resolution of the pandemic. The pandemic has significantly impacted economies worldwide, which could result in adverse effects on our business and operations. Moreover, the pandemic has caused substantial disruption in the global financial markets and supply chains and may continue to adversely impact economies worldwide, which could result in adverse effects on our business and operations as well as the volatility of our stock price and trading in our stock.

We are implementing a multi-stage return to office plan, and in October 2021 we opened our facilities to all employees who expressed interest in participating in a return-to-office pilot program, which is expected to continue through the end of 2021. In the meantime, many of our employees will continue to work in a hybrid remote operating model. Our laboratory scientists who engage in research activities now have full access to our laboratories. We are implementing our return to office plan and making these evaluations based on guidance from federal, state and local government authorities, and we expect that some form of a hybrid model will continue for us in the near future. Changes in guidance from federal, state and local government authorities could impact our return to office plan, and require us to increasingly rely on personnel working from home. For example, changes to guidance from federal, state and local government authorities to restrict or limit in-person interactions could result in our laboratory staff that is presently engaged in research and development activities to have restricted access to laboratories. Such restricted access could delay timely completion of preclinical activities and the initiation of additional clinical trials for other of our development programs.

A remote or hybrid operating model may also negatively impact productivity, or disrupt, delay, or otherwise adversely impact our business. In addition, this could increase our cyber security risk, create data accessibility concerns, and make us more susceptible to communication disruptions, any of which could adversely impact our business operations or delay necessary interactions with state, local and federal regulators, ethics committees, manufacturing sites, research or clinical trial sites and other important agencies and contractors, including our CROs and CMOs.

Due to the evolving and uncertain global impacts of the COVID-19 pandemic, we cannot precisely determine or quantify the impact that the COVID-19 pandemic has had or will have on our business, financial condition, results of operations, and prospects for the fiscal year ending December 31, 2021 and beyond.

Stock Option Agreement

Incorporated Terms and Conditions

1.
Grant of Option.

This agreement evidences the grant by the Company, on the grant date (the “Grant Date”) set forth in the Notice of Grant that forms part of this agreement (the “Notice of Grant”), to the Participant of an option to purchase, in whole or in part, on the terms provided herein, the number of Shares set forth in the Notice of Grant of common stock, $0.0001 par value per share, of the Company (“Common Stock”), at the exercise price per Share set forth in the Notice of Grant. Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on the Final Exercise Date set forth in the Notice of Grant (the “Final Exercise Date”).

The option evidenced by this agreement is being granted to the Participant pursuant to the inducement grant exception under Nasdaq Stock Market Rule 5635(c)(4) as an inducement that is material to the Participant’s employment with the Company, and not pursuant to the Company’s 2013 Stock Incentive Plan, or any equity incentive plan of the Company.

The option evidenced by this agreement shall not be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”). Except as otherwise indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms.

2.
Vesting Schedule.

This option will become exercisable (“vest”) in accordance with the vesting schedule set forth in the Notice of Grant. Any fractional number resulting from the vesting schedule set forth in the Notice of Grant shall be rounded down to the nearest whole number except with respect to the last vesting period.

The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 or Section 6(c) hereof.

3.
Exercise of Option.
(a)
Form of Exercise. Each election to exercise this option shall be in writing, in the form of the Stock Option Exercise Notice attached as Annex A, signed by the Participant, and received by the Company at its principal office, accompanied by this agreement, or in such other form (which may be electronic) as is approved by the Company, together with payment in full in the manner provided in this Section 3(a). The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share. Payment shall be made as follows.

(1) in cash or by check, payable to the order of the Company;

- 2 -

 


(2) except as may otherwise be approved by the Board of Directors of the Company (the “Board”), in its sole discretion, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding;

(3) to the extent approved by the Board, in its sole discretion, by delivery (either by actual delivery or attestation) of shares of Common Stock owned by the Participant valued at their fair market value (valued in the manner determined by (or in a manner approved by) the Board (the “Fair Market Value”)), provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant for such minimum period of time, if any, as may be established by the Board in its discretion and (iii) such Common Stock is not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements;

(4) to the extent approved by the Board in its sole discretion, by delivery of a notice of “net exercise” to the Company, as a result of which the Participant would receive (i) the number of shares underlying the portion of the option being exercised, less (ii) such number of shares as is equal to (A) the aggregate exercise price for the portion of the option being exercised divided by (B) the Fair Market Value on the date of exercise;

(5) to the extent permitted by applicable law and approved by the Board, in its sole discretion, by payment of such other lawful consideration as the Board may determine; or

(6) by any combination of the above permitted forms of payment.

(b)
Continuous Relationship with the Company Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee, director or officer of, or consultant or advisor to (as such terms are defined and interpreted for purposes of Form S-8 under the Securities Act of 1933, as amended), the Company or any present or future parent or subsidiary corporations of the Company as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations thereunder (the “Code”) (an “Eligible Participant”).
(c)
Termination of Relationship with the Company. If the Participant ceases to be an Eligible Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall be exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the restrictive covenants (including, without limitation, the non-competition, non-solicitation, or confidentiality provisions) of any employment contract, any non-competition, non-solicitation, confidentiality or assignment agreement to which the Participant is a party, or any other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon such violation.

- 3 -

 


(d)
Exercise Period Upon Death or Disability. If the Participant dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below, this option shall be exercisable, within the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date.
(e)
Termination for Cause. If, prior to the Final Exercise Date, the Participant’s employment or other relationship is terminated by the Company for Cause (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such termination of employment or other relationship. If, prior to the Final Exercise Date, the Participant is given notice by the Company of the termination of his or her employment or other relationship by the Company for Cause, and the effective date of such employment or other termination is subsequent to the date of delivery of such notice, the right to exercise this option shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment or other relationship shall not be terminated for Cause as provided in such notice or (ii) the effective date of such termination of employment or other relationship (in which case the right to exercise this option shall, pursuant to the preceding sentence, terminate upon the effective date of such termination of employment or other relationship). If the Participant is subject to an individual employment, consulting or severance agreement with the Company or eligible to participate in a Company severance plan or arrangement, in any case which agreement, plan or arrangement contains a definition of “cause” for termination of employment or other relationship, “Cause” shall have the meaning ascribed to such term in such agreement, plan or arrangement. Otherwise, “Cause” shall mean willful misconduct by the Participant or willful failure by the Participant to perform his or her responsibilities to the Company (including, without limitation, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure, non-competition or other similar agreement between the Participant and the Company), as determined by the Company, which determination shall be conclusive. The Participant’s employment or other relationship shall be considered to have been terminated for Cause if the Company determines, within 30 days after the Participant’s resignation, that termination for Cause was warranted.
4.
Tax Matters. The Participant must satisfy all applicable federal, state, and local or other income and employment tax withholding obligations before the Company will deliver stock certificates or otherwise recognize ownership of Common Stock under this option. The Company may decide to satisfy the withholding obligations through additional withholding on salary or wages. If the Company elects not to or cannot withhold from other compensation, the Participant must pay the Company the full amount, if any, required for withholding or have a broker tender to the Company cash equal to the withholding obligations. Payment of withholding obligations is due before the Company will issue any shares on exercise of this option or at the same time as payment of the exercise or purchase price, unless the Company determines otherwise. If approved by the Board in its sole discretion, the Participant may satisfy such tax obligations in whole or in part by delivery (either by actual delivery or attestation) of

- 4 -

 


shares of Common Stock underlying this option, valued at their Fair Market Value; provided, however, except as otherwise provided by the Board, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income). Shares used to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.
5.
Transfer Restrictions.

This option may not be sold, assigned, transferred, pledged, encumbered or otherwise disposed of by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant.

 

6.
Adjustments for Changes in Common Stock and Certain Other Events.
(a)
Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, the number and class of securities and exercise price per share of this option shall be equitably adjusted by the Company (or substituted options may be made, if applicable) in the manner determined by the Board. Without limiting the generality of the foregoing, in the event the Company effects a split of the Common Stock by means of a stock dividend and the exercise price of and the number of shares subject to this option are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), then the Participant, if he or she exercises this option between the record date and the distribution date for such stock dividend shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend.
(b)
Reorganization Events. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer or disposition of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any liquidation or dissolution of the Company.
(c)
Consequences of a Reorganization Event.

(1) In connection with a Reorganization Event, the Board may take any one or more of the following actions with respect to this option (or any portion thereof) on such terms as the Board determines (except to the extent specifically provided otherwise in an another agreement between the Company and the Participant): (i) provide that this option shall be assumed, or a substantially equivalent option shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to the Participant, provide that all of

- 5 -

 


the unexercised or unvested portion of this option will terminate immediately prior to the consummation of such Reorganization Event unless exercised by the Participant (to the extent then exercisable) within a specified period following the date of such notice, (iii) provide that this option shall become exercisable, in whole or in part, prior to or upon such Reorganization Event, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to the Participant with respect to this option equal to (A) the number of shares of Common Stock subject to the vested portion of this option (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such Reorganization Event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) the exercise price of this option and any applicable tax withholdings, in exchange for the termination of this option, (v) provide that, in connection with a liquidation or dissolution of the Company, this option shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings) and (vi) any combination of the foregoing.

(2). For purposes of Section 6(c)(1)(i), this option shall be considered assumed if, following consummation of the Reorganization Event, this option confers the right to purchase, for each share of Common Stock subject to this option immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise or settlement of this option to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event.

7.
Miscellaneous.
(a)
No Right To Employment or Other Status. The grant of this option shall not be construed as giving the Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with the Participant free from any liability or claim hereunder.

Restricted Stock Unit Award Agreement
Incorporated Terms and Conditions

The terms and conditions of the award of RSUs made to the Participant, as set forth in the Notice of Grant that forms part of this Agreement (the “Notice of Grant”) as set forth on the previous page of this Agreement, are as follows:

1.
Grant of Restricted Stock Units.

The RSUs are issued to the Participant, effective as of the Grant Date set forth in the Notice of Grant, in consideration of services to be rendered by the Participant to the Company. The RSUs are being granted to the Participant pursuant to the inducement grant exception under Nasdaq Stock Market Rule 5635(c)(4), and not pursuant to the Company’s 2013 Equity Incentive Plan or any equity incentive plan of the Company, as an inducement that is material to the Participant’s employment with the Company.

2.
Vesting Schedule. Unless otherwise provided in this Agreement, the RSUs shall vest in accordance with the vesting schedule set forth in the Notice of Grant. Any fractional shares that would otherwise vest as of a particular date will be rounded down and carried forward to the next vesting date until a whole share can be issued. Upon the vesting of this award, the Company shall deliver, for each RSU that becomes vested, one (1) share of common stock, $0.0001 par value per share, of the Company (the “Common Stock”). The Common Stock shall be delivered as soon as practicable following each vesting date or event set forth in the Notice of Grant, but in any case, within thirty (30) days after such date or event.
3.
Termination of Relationship.

If the Participant ceases to be an employee, director or officer of, or consultant or advisor to (as such terms are defined and interpreted for purposes of Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”)), the Company or any present or future parent or subsidiary corporations of the Company as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations thereunder (the “Code”) (an “Eligible Participant”) for any reason or no reason, with or without cause, all of the RSUs that are unvested as of the time of such cessation shall be forfeited immediately and automatically to the Company, without the payment of any consideration to the Participant, effective as of such cessation. The Participant shall have no further rights with respect to any RSUs that are so forfeited. If the Participant provides services to a subsidiary of the Company, any references in this Agreement to employment by or a relationship with the Company shall instead be deemed to refer to employment by or a relationship with such subsidiary.

Notwithstanding any other provision of this Agreement or any other agreement (written or oral) to the contrary, the Participant shall not be entitled (and by entering into this Agreement, hereby irrevocably waives any such entitlement) to any payment or other benefit to compensate the Participant for the loss of any rights under this Agreement as a result of the termination or expiration of the RSUs in connection with any termination of the Participant’s relationship with the Company.

- 2 -

 

 


 

4.
Transfer Restrictions.

The RSUs may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law or otherwise, except by will or the laws of descent and distribution or pursuant to a qualified domestic relations order; provided, however, that the Participant may make a gratuitous transfer of the RSUs to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the Participant and/or an immediate family member thereof if the Company would be eligible to use a Form S-8 under the Securities Act for the registration of the sale of the Common Stock subject to the RSUs to such proposed transferee, provided further, that the Company shall not be required to recognize any such permitted transfer until such time as such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of the RSUs. References to the Participant, to the extent relevant in the context, shall include references to authorized transferees. For the avoidance of doubt, nothing contained in this Section 4 shall be deemed to restrict a transfer to the Company

5.
Rights as a Stockholder.

The Participant shall have no rights as a stockholder of the Company with respect to any shares of Common Stock underlying or relating to the RSUs until the issuance of such Common Stock to the Participant in respect of the RSUs. The Participant shall have no voting rights with respect to the RSUs.

6.
Tax Obligations.
(a)
Acknowledgments; No Section 83(b) Election. The Participant acknowledges that he or she is responsible for obtaining the advice of the Participant’s own tax advisors with respect to the award of RSUs and the Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents with respect to the tax consequences relating to the RSUs. The Participant understands that the Participant (and not the Company) shall be responsible for the Participant’s tax liability that may arise in connection with the acquisition, vesting and/or disposition of the RSUs. The Participant acknowledges that no election under Section 83(b) of the Code, is available with respect to RSUs.
(b)
Withholding. The Participant acknowledges and agrees that the Company has the right to deduct from payments of any kind otherwise due to the Participant any federal, state, local or other taxes of any kind required by law to be withheld with respect to the vesting of the RSUs. At such time as the Participant is not aware of any material nonpublic information about the Company or the Common Stock and is not subject to a blackout period under the Company’s insider trading policy, the Participant may execute the instructions set forth in Exhibit A attached hereto (the “Durable Automatic Sale Instructions”) as the means of satisfying such tax obligation. If the Participant does not execute the Durable Automatic Sale Instructions prior to an applicable vesting date, then the Participant agrees that, if under applicable law the Participant will owe taxes at such vesting date on the portion of the RSUs then vested, the Company shall be entitled to immediate payment from the Participant of the amount of any tax required to be withheld by the Company. Notwithstanding the foregoing, if the Participant is unable to execute the Durable Automatic Sale Instructions prior to one or more vesting dates or events under this Agreement because the Participant has been in continuous possession of material nonpublic information about the Company or the Common Stock or otherwise subject to a blackout period between the Grant Date of the RSUs and the applicable vesting date or event, then the Participant acknowledges and agrees that the withholding shall be satisfied by the Company retaining from the number of shares of Common Stock otherwise issuable to the Participant on the applicable vesting date or event, a number

- 3 -

 

 


 

of shares of Common Stock having a fair market value equal to the amount of withholding tax required to be paid to the Company by the Participant. The Company is not obligated to, and shall not, deliver any shares of Common Stock to the Participant until it is satisfied that all required withholdings have been made.
7.
Adjustments for Changes in Common Stock and Certain Other Events.
(a)
Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of Common Stock other than an ordinary cash dividend, the number and class of securities and the share and per-share-related provisions of each outstanding RSU, shall be equitably adjusted by the Company (or substituted RSUs may be granted, if applicable) in the manner determined by the Board of Directors of the Company (the “Board”).
(b)
Reorganization Events.
i.
Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer or disposition of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any liquidation or dissolution of the Company.
ii.
Consequences of a Reorganization Event on the RSUs.
1.
In connection with a Reorganization Event, the Board may take any one or more of the following actions as to all or any of the outstanding RSUs (or any portion thereof) on such terms as the Board determines (except to the extent specifically provided in another agreement between the Company and the Participant): (i) provide that the RSUs shall be assumed, or substantially equivalent RSUs shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to the Participant, provide that the Participant’s unvested portion of the RSUs will terminate immediately prior to the consummation of such Reorganization Event, (iii) provide that the RSUs shall become realizable, or deliverable, or restrictions applicable to the RSUs shall lapse, in whole or in part prior to or upon such Reorganization Event, (iv) in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share surrendered in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to the Participant with respect to the RSUs equal to (A) the number of shares of Common Stock subject to the vested portion of the RSUs (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such Reorganization Event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) any applicable tax withholdings, in exchange for the termination of the RSUs, (v) provide that, in connection with a liquidation or dissolution of the Company, the RSUs shall convert into the right to receive liquidation proceeds (net of any applicable tax withholdings) and (vi) any combination of the foregoing.
2.
Notwithstanding the terms of Section 7(b)(ii)(1)(A), in the case of outstanding RSUs that are subject to Section 409A of the Code: the Board may only undertake the actions set forth in clauses (iii), (iv) or (v) of Section 7(b)(ii)(1) if the Reorganization Event constitutes a “change in control event” as defined under Treasury Regulation Section 1.409A-3(i)(5)(i) and such action is permitted or required by Section 409A of the Code; if the Reorganization Event is not a “change in control event” as so defined or such action is not permitted or required by Section 409A of the Code, and the acquiring or succeeding corporation does not

- 4 -

 

 


 

assume or substitute the RSUs pursuant to clause (i) of Section 7(b)(ii)(1), then the unvested portion of the RSUs shall terminate immediately prior to the consummation of the Reorganization Event without any payment in exchange therefor.
3.
For purposes of Section 7(b)(ii)(1)(i), the RSUs shall be considered assumed if, following consummation of the Reorganization Event, the RSUs confer the right to receive, for each share of Common Stock subject to the RSU immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the settlement of the RSUs to consist solely of such number of shares of common stock of the acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event.
8.
Miscellaneous.
(a)
Section 409A. If and to the extent (i) any portion of any payment, compensation or other benefit provided to the Participant in connection with his or her employment termination constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code and (ii) the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in accordance with its procedures, by which determinations the Participant (through accepting the RSUs) agrees that he or she is bound, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of “separation from service” (as determined under Section 409A of the Code) (the “New Payment Date”), except as Section 409A of the Code may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule. The Company makes no representations or warranty and shall have no liability to the Participant or any other person if any provisions of or payments, compensation or other benefits hereunder are determined to constitute nonqualified deferred compensation subject to Section 409A of the Code but do not to satisfy the conditions of that section.
(b)
Amendment. The Board may amend, modify or terminate this Agreement, including but not limited to, substituting RSUs and changing the date of settlement or realization.

Exhibit A

DURABLE AUTOMATIC SALE INSTRUCTION

 

This Durable Automatic Sale Instruction is being delivered to Epizyme, Inc. (the “Company”) by the undersigned on the date set forth below.

 

I hereby acknowledge that the Company has granted, or may in the future from time to time grant, to me restricted stock units (“RSUs”).

 

I acknowledge that upon the vesting dates applicable to any such RSUs, I will have compensation income equal to the fair market value of the shares of the Company’s common stock subject to the RSUs that vest on such date and that the Company is required to withhold income and employment taxes in respect of that compensation income on the applicable vesting date.

 

I desire to establish a process to satisfy such withholding obligation in respect of all RSUs that have been, or may in the future be, granted by the Company to me through an automatic sale of a portion of the shares of the Company’s common stock that would otherwise be issued to me on each applicable vesting date, such portion to be in an amount sufficient to satisfy such withholding obligation, with the proceeds of such sale delivered to the Company in satisfaction of such withholding obligation.

I understand that the Company has arranged for the administration and execution of its equity incentive plans and the sale of certain Company securities pursuant to an Internet-based platform administered by a third party (the “Administrator”) and the Administrator’s designated brokerage partner.

Upon any vesting of my RSUs from and after the date of this Durable Automatic Sale Instruction, I hereby appoint the Administrator (or any successor administrator) to automatically sell such number of shares of the Company’s common stock issuable with respect to my RSUs that vest as is sufficient to generate net proceeds sufficient to satisfy the Company’s minimum statutory withholding obligations with respect to the income recognized by me upon the vesting of the RSUs (based on minimum statutory withholding rates for all tax purposes, including payroll and social security taxes, that are applicable to such income), and the Company shall receive such net proceeds in satisfaction of such tax withholding obligation.

I hereby appoint the Chief Executive Officer, the Chief Financial Officer and the General Counsel of the Company, and any of them acting alone and with full power of substitution, to serve as my attorneys in fact to arrange for the sale of shares of common stock in accordance with this these durable automatic sale instructions unless and until I notify the Company in writing of my revocation of these durable automatic sale instructions which revocation may be undertaken only in accordance with the Company’s insider trading policy and other applicable policies, as well as applicable securities laws. I agree to execute and deliver such documents, instruments and certificates as may reasonably be required in connection with the sale of the shares of common stock pursuant to these durable automatic sale instructions.

 

By signing below, I hereby represent to the Company that, as of the date hereof, I am not aware of any material nonpublic information about the Company or its common stock and that I am not prohibited from entering into these durable automatic sale instructions by the Company’s insider trading policy or otherwise. I have structured these automatic sale instructions to constitute a “binding contract” relating to the sale of common

stock, consistent with the affirmative defense to liability under Section 10(b) of the Securities Exchange Act of 1934 under Rule 10b5-1(c) promulgated under such Act.

Performance of Services. Mr. Bazemore shall have the right to control and determine the methods, manner and means of performing the Services. In performing the Services, the amount of time devoted by Mr. Bazemore on any given day will be entirely within Mr. Bazemore’s control, and the Company will rely on Mr. Bazemore to put in the amount of time as is necessary to fulfill the requirements of this Agreement. However, the Services contemplated by this Agreement must meet the Company’s standards and approval and shall be subject to the Company’s general right of inspection and supervision to secure their satisfactory completion. Mr. Bazemore will provide all equipment and supplies required to perform the Services.
b.
Non-Exclusivity. Mr. Bazemore retains the right to contract with other companies or entities for his consulting services without restriction, provided, however, that Mr. Bazemore remains in compliance with the terms of the Employee Invention and Non-Disclosure Agreement that he previously executed for the benefit of the Company and which remains in full force and effect (the “Restrictive Covenant Agreement”). Likewise, the Company retains a reciprocal right to contract with other companies and/or individuals for consulting services without restriction.
c.
Scope of Authority. Mr. Bazemore is not authorized to transact business, incur obligations, sell goods, receive payments, solicit orders or assign or create any obligation of any kind, express or implied, on behalf of the Company or any of the Company's related or affiliated entities, or to bind in any way whatsoever, or to make any promise, warranty or representation on behalf of the Company or any of the Company's related or affiliated entities with respect to any matter, except as directed by the Chief Executive Officer of the Company. Mr. Bazemore shall not use the Company's trade names, trademarks, service names or servicemarks without the prior approval of the Company.

5.
Termination. This Agreement may be terminated prior to the end of the Consultation Period in the following manner: (a) by the Company at any time immediately upon written notice if Mr. Bazemore has materially breached this Agreement, the Release of Claims or the Restrictive Covenant Agreement and, to the extent curable, has not cured such breach within thirty (30) days following written notice of the breach from the Company; (b) by Mr. Bazemore at any time immediately upon written notice if the Company has materially breached this Agreement and, to the extent curable, has not cured such breach within thirty (30) days following written notice of the breach from Mr. Bazemore ; (c) by Mr. Bazemore upon not less than thirty (30) days’ prior written notice for any reason; or (d) at any time upon the mutual written consent of the parties hereto. Notwithstanding the foregoing, and for the avoidance of doubt, the Company may terminate this Agreement effective immediately by giving written notice to Mr. Bazemore if Mr. Bazemore fails to sign the Release of Claims by August 31, 2021 or revokes the Release of Claims within seven (7) days after signing it as set forth in the Release of Claims. In the event of any termination, Mr. Bazemore shall be entitled only to reimbursements for expenses incurred in accordance with Section 3(d) prior to termination, and no further payments of any kind will be due. In addition, vesting of Mr. Bazemore’s equity awards will cease immediately upon termination. Any written notice under this Section 5 shall explain the reason for the termination.
6.
Proprietary Information and Inventions.

6.1 Proprietary Information.

a.
Mr. Bazemore acknowledges that his relationship with the Company is one of high trust and confidence and that in the course of his service to the Company, Mr. Bazemore will have access to and contact with Proprietary Information. Mr. Bazemore will not disclose any Proprietary Information to any person or entity other than employees of the Company or use the same for any purposes (other than in the performance of the services) without written approval by an officer of the Company, either during or after the Consultation Period, unless and until such Proprietary Information has become public knowledge without fault by Mr. Bazemore.
b.
For purposes of this Agreement, Proprietary Information shall mean, by way of illustration and not limitation, all information, whether or not in writing, whether or not patentable and whether or not copyrightable, of a private, secret or confidential nature, owned, possessed or used by the Company, concerning the Company’s business, business relationships or financial affairs, including, without limitation, any Invention, formula, vendor information, customer information, apparatus, equipment, trade secret, process, research, report, technical or research data, clinical data, know-how, computer program, software, software documentation, hardware design, technology, product, processes, methods, techniques, formulas, compounds, projects, developments, marketing or business plan, forecast, unpublished financial statement, budget, license, price, cost, customer, supplier or personnel information or employee list that is communicated to, learned of, developed or otherwise acquired by Mr. Bazemore in the course of his service as a consultant to the Company.
c.
Mr. Bazemore agrees that all files, documents, letters, memoranda, reports, records, data sketches, drawings, models, laboratory notebooks, program listings, computer equipment or devices, computer programs or other written, photographic, or other tangible material containing Proprietary Information, whether created by Mr. Bazemore or others, which shall come into Mr. Bazemore’s custody or possession, shall be and are the exclusive property of Mr. Bazemore to be used by Mr. Bazemore only in the performance of his duties for the Company and shall not be copied or removed from the Company premises except in the pursuit of the business of the Company. All such materials or copies thereof and all tangible property of the Company in the custody or possession of Mr. Bazemore shall be delivered to the Company, upon the earlier of (i) a request by the Company or (ii) the termination of this Agreement. After such delivery, Mr. Bazemore shall not retain any such materials or copies thereof or any such tangible property.
d.
Mr. Bazemore agrees that his obligation not to disclose or to use information and materials of the types set forth in paragraphs (b) and (c) above, and Mr. Bazemore’s obligation to return materials and tangible property set forth in paragraph (c) above extends to such types of information, materials and tangible property of customers of the Company or suppliers to the Company or other third parties who may have disclosed or entrusted the same to the Company or to Mr. Bazemore.

3

 

 


 

 

e.
Mr. Bazemore acknowledges that the Company from time to time may have agreements with other persons or with the United States Government, or agencies thereof, that impose obligations or restrictions on the Company regarding inventions made during the course of work under such agreements or regarding the confidential nature of such work. Mr. Bazemore agrees to be bound by all such obligations and restrictions that are known to Mr. Bazemore and to take all action necessary to discharge the obligations of the Company under such agreements.
f.
Mr. Bazemore’s obligations under this Section 6.1 shall not apply to any information that (i) is or becomes known to the general public under circumstances involving no breach by Mr. Bazemore or others of the terms of this Section 6.1, (ii) is generally disclosed to third parties by the Company without restriction on such third parties, or (iii) is approved for release by written authorization of an officer of the Company. Further, nothing herein prohibits Mr. Bazemore from communicating with government agencies about possible violations of federal, state, or local laws or otherwise providing information to government agencies or participating in government agency investigations or proceedings. In addition, notwithstanding Mr. Bazemore’s confidentiality and nondisclosure obligations, Mr. Bazemore is hereby advised as follows pursuant to the Defend Trade Secrets Act: “An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.”

6.2 Inventions.

a.
Mr. Bazemore will make full and prompt disclosure to the Company of all inventions, creations, improvements, enhancements, designs, innovations, discoveries, processes, methods, techniques, developments, software, computer programs, and works of authorship, whether or not patentable and whether or not copyrightable, that are created, made, conceived or reduced to practice by Mr. Bazemore or under his direction or jointly with others (i) during the Consultation Period if made for the Company in the course of the performance of the Services hereunder or (ii) during or after the Consultation Period if resulting or derived from Proprietary Information, whether or not during normal working hours or on the premises of the Company (all of which are collectively referred to in this Agreement as “Inventions”). Mr. Bazemore agrees to assign and does hereby assign to the Company (or any person or entity designated by the Company) all of Mr. Bazemore’s right, title and interest in and to all Inventions and all related patents, patent applications, copyrights created in the work(s) of authorship, trademarks, trade names, and other industrial and intellectual property rights and applications therefor in the United States and elsewhere. However, clause (i) of this subsection (a) shall not apply to Inventions that do not relate to the present or planned business or research and development of the Company and that are made and conceived by Mr. Bazemore not during normal working hours, not on the Company’s premises and not using the Company’s tools, devices, equipment or Proprietary Information. Mr. Bazemore understands that, to the extent this Agreement shall be construed in accordance with the laws of any state that precludes a requirement that an individual assign certain classes of inventions, this Section 6.2(a) shall be interpreted not to apply to any invention that a court rules and/or the Company agrees falls within such classes. Mr. Bazemore further acknowledges that each original work of authorship that is made by Mr. Bazemore (solely or jointly with others) within the scope of the Agreement and which is protectable by copyright is a “work made for hire,” as that term is defined in the United States Copyright Act. Mr. Bazemore hereby waives all claims to moral rights in any Inventions.
b.
Mr. Bazemore agrees that if, in the course of performing the services, he incorporates into any Invention developed under this Agreement any preexisting invention, improvement, development, concept, discovery or other proprietary information owned by Mr. Bazemore or in which Mr. Bazemore has an interest (“Prior Inventions”), (i) Mr. Bazemore will inform the Company, in writing before incorporating such Prior Inventions into any Invention, and (ii) the Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, transferable worldwide license with the right to grant and authorize sublicenses, to make, have made, modify, use, import, offer for sale, sell, reproduce, distribute, modify, adapt, prepare derivative works of, display, perform, and otherwise exploit such Prior Inventions, without restriction, including, without limitation, as part of or in connection with such Invention,

4

 

 


 

 

and to practice any method related thereto. Mr. Bazemore will not incorporate any invention, improvement, development, concept, discovery or other proprietary information owned by any third party into any Invention without the Company’s prior written permission.
c.
Mr. Bazemore agrees to cooperate fully with the Company, both during and after the Consultation Period, with respect to the procurement, maintenance, and enforcement of copyrights, patents and other intellectual property rights (both in the United States and foreign countries) relating to Inventions. Mr. Bazemore shall sign all papers, including, without limitation, copyright applications, patent applications, declarations, oaths, formal assignments, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect its rights and interests in any Invention. Mr. Bazemore further agrees that if the Company is unable, after reasonable effort, to secure the signature of Mr. Bazemore on any such papers, any executive officer of the Company shall be entitled to execute any such papers as the agent and the attorney-in-fact of Mr. Bazemore, and Mr. Bazemore hereby irrevocably designates and appoints each executive officer of the Company as Mr. Bazemore’s agent and attorney-in-fact to execute any such papers on Mr. Bazemore’s behalf, and to take any and all actions as the Company may deem necessary or desirable in order to protect its rights and interests in any Invention, under the conditions described in this sentence.
d.
Mr. Bazemore shall maintain adequate and current written records (in the form of notes, sketches, drawings and as may be specified by the Company) to document the conception and/or first actual reduction to practice of any Invention. Such written records shall be available to and remain the sole property of the Company at all times.
7.
Other Agreements. Mr. Bazemore hereby represents that, except as Mr. Bazemore has disclosed in writing to the Company, Mr. Bazemore is not bound by the terms of any agreement with any third party to refrain from using or disclosing any trade secret or confidential or proprietary information in the course of his consultancy with the Company, to refrain from competing, directly or indirectly, with the business of such third party or to refrain from soliciting employees, customers or suppliers of such third party. Mr. Bazemore further represents that his performance of all the terms of this Agreement and the performance of the Services as a consultant of the Company do not and will not breach any agreement with any third party to which Mr. Bazemore is a party (including without limitation any nondisclosure or non-competition agreement), and that Mr. Bazemore will not disclose to the Company or induce the Company to use any confidential or proprietary information or material belonging to any current or previous employer or others.
8.
Warranties. Mr. Bazemore will assume sole responsibility for his/her compliance with applicable federal and state laws and regulations, and shall rely exclusively upon his/her own determination, or that of his/her legal advisers, that the performance of the Services and the receipt of the Consulting Benefits hereunder comply with such laws and regulations. Mr. Bazemore shall be solely responsible for all state and federal income taxes, unemployment insurance and social security taxes in connection with this Agreement and for maintaining adequate workers’ compensation insurance coverage. Mr. Bazemore acknowledges that he is not relying upon the advice or representation of the Company with respect to the tax treatment of the Consulting Benefits.
9.
Non-Assignability of Contract. This Agreement shall be binding upon, and inure to the benefit of, both parties and their respective successors and assigns, including any entity with which, or into which, the Company may be merged or which may succeed to its assets or business, provided, however, that the obligations of Mr. Bazemore are personal and shall not be assigned by him.
10.
Notices. All notices required or permitted under this Agreement shall be in writing and shall be deemed effective upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail, postage prepaid, addressed to the other party at such address or addresses as either party shall designate to the other.
11.
Complete Agreement. Mr. Bazemore acknowledges that this Agreement, together with the Release of Claims, the Restrictive Covenant Agreement, the Options and the Restricted Stock Units, contains the entire understanding between the parties and supersedes, replaces and takes precedence over any prior understanding or oral or written agreement between the parties respecting the subject matter of this Agreement, the Release of Claims, the Options or the Restricted Stock Units. Mr. Bazemore further acknowledges that he is not eligible to receive any payments or benefits under the terms of his offer letter dated August 5, 2015 or the Company’s Executive Severance and Change in Control Plan. There are no representations, agreements, arrangements, nor understandings, oral or

5

 

 


 

 

written, between the parties relating to the subject matter of this Agreement that are not fully expressed herein and in the Release of Claims.
12.
Severability. In the event any provision of this Agreement shall be held invalid, the same shall not invalidate or otherwise affect in any respect any other term or terms of this Agreement, which term or terms shall remain in full force and effect.
13.
Non-Waiver. No delay or omission by the Company in exercising any right under this Agreement shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar to or waiver of any right on any other occasion.
14.
Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and Mr. Bazemore.
15.
Counterparts. This Agreement may be executed in two (2) signed counterparts, each of which shall constitute an original, but all of which taken together shall constitute one and the same instrument.
16.
Interpretation. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular forms of nouns and pronouns shall include the plural, and vice versa. The captions of the sections of this Agreement are for convenience of reference only and in no way define, limit or affect the scope or substance of any section of this Agreement.
17.
Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts without giving effect to any choice or conflict of law provision or rule (whether of the Commonwealth of Massachusetts or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the Commonwealth of Massachusetts.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date and year first above written.

8

 

 


 

 

individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.”
9.

Your full cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with the Company’s counsel, at reasonable times and locations designated by the Company, to investigate or prepare the Company’s claims or defenses, to prepare for trial or discovery or an administrative hearing, mediation, arbitration or other proceeding and to act as a witness when requested by the Company. You further agree that, to the extent permitted by law, you will notify the Company promptly in the event that you are served with a subpoena (other than a subpoena issued by a government agency), or in the event that you are asked to provide a third party (other than a government agency) with information concerning any actual or potential complaint or claim against the Company. The Company will pay for your reasonable and documented expenses for your compliance with this obligation.
10.
Amendment and Waiver. This Release of Claims shall be binding upon the parties and may not be modified in any manner, except by an instrument in writing of concurrent or subsequent date signed by duly authorized representatives of the parties hereto. This Release of Claims is binding upon and shall inure to the benefit of the parties and their respective agents, assigns, heirs, executors, successors and administrators. No delay or omission by the Company in exercising any right under this Release of Claims shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar to or waiver of any right on any other occasion.

14.
Entire Agreement. This Release of Claims, along with the Consulting Agreement, contains and constitutes the entire understanding and agreement between the parties hereto with respect to your severance benefits and the settlement of claims against the Company and cancels all previous oral and written negotiations, agreements, and commitments in connection therewith.

Other Combination Drug that are needed in order to Develop, Manufacture or Commercialize any Combination Therapy in accordance with the terms of this Agreement.

Hutchmed may only subcontract any of Hutchmed’s obligations hereunder (subject to Sections 2.6(b) and 9.10) to Affiliates of Hutchmed or to Permitted Subcontractors. For clarity, a sublicense or subcontract to an Affiliate of Hutchmed shall automatically terminate if such entity ceases to be an Affiliate of Hutchmed, and, subject to Section 14.7(a), any sublicense or subcontract to an Affiliate of Hutchmed or a Third Party shall automatically terminate if the relevant license granted to Hutchmed by Epizyme under Section 2.1 terminates.

Hutchmed shall provide a true and complete copy of any sublicense agreement with any Affiliate or Third Party or any subcontract with a Permitted Subcontractor contract research organization for any Joint Global Trials as described in Section 1.145(a) (and if any such sublicense agreement or subcontract is not in English, an English translation thereof), and otherwise a summary of other material subcontracts in English, in each case, subject to Hutchmed’s right to redact any confidential or proprietary information contained therein that is not necessary for Epizyme to determine the scope of the sublicense or subcontract or the compliance with the terms and conditions of this Agreement.

Hutchmed will be responsible for ensuring that all agreements with Sublicensees or Permitted Subcontractors: (A) do not conflict with the terms of this Agreement, (B) allow Hutchmed to provide Epizyme with access to and use of the data and samples (with respect to samples to the extent permitted by Applicable Law) generated or obtained in the performance of activities under this Agreement to the extent Hutchmed would be obligated to provide such access and use, and other information and documents as required pursuant to this Agreement (and in no event less than the same use rights granted to Epizyme (to the extent applicable)), (C) do not impose a new obligation, whether direct, indirect, or contingent, upon Epizyme that is not set forth in this Agreement, and (D) comply with Applicable Law.

Hutchmed shall remain primarily liable to Epizyme for the performance of all of its obligations under, and Hutchmed’s compliance with all provisions of, this Agreement. Hutchmed shall be fully responsible and liable for the acts or omissions of all Hutchmed Entities with respect to this Agreement including any breach of the terms

23

 


 

 

of this Agreement by any Hutchmed Entity to the same extent as if Hutchmed has committed any such breach and will terminate promptly the agreement with any Sublicensee or Permitted Subcontractor if such Sublicensee or Permitted Subcontractor takes or fails to take any action that, if taken or not taken by Hutchmed, as applicable, would constitute a material breach of this Agreement and does not cure such breach in a timely manner in accordance with Section 14.4.

Epizyme shall use Commercially Reasonable Efforts to ensure that all Epizyme Entities comply in all material respects with all applicable provisions of this Agreement and Applicable Law. Epizyme shall remain primarily liable to Hutchmed for the performance of all of its obligations under, and Epizyme’s compliance with all provisions of, this Agreement. Epizyme shall be fully responsible and liable for the acts or omissions of all Epizyme Entities with respect to this Agreement including any breach of the terms of this Agreement by any Epizyme Entity to the same extent as if Epizyme has committed any such breach and will terminate promptly the agreement with any Epizyme Entity if such Epizyme Entity takes or fails to take any action that, if taken or not taken by Epizyme, as applicable, would constitute a material breach of this Agreement and does not cure such breach in a timely manner in accordance with Section 14.4.

2.5 No Other Rights and Retained Rights. Nothing in this Agreement shall be interpreted to grant either Party any rights under any Patent Rights or Know-How Controlled by the other Party that are not expressly granted herein, whether by implication, estoppel or otherwise, and, notwithstanding the foregoing provisions of Sections 2.1, 2.2 and 2.3, neither Party grants any right or license in this Agreement to the other Party under Patent Rights or Know-How Controlled by such Party with respect to active pharmaceutical ingredients or drug products other than the Licensed Compound and Licensed Products. Any rights not expressly granted to a Party by the other Party under this Agreement are hereby retained by such other Party. For clarity, Epizyme and any of its Affiliates may, subject to Section 4.6, Develop Licensed Products (as monotherapies or as the Licensed Product component of Combination Therapies) and may Manufacture Licensed Products in the Territory, in each case in support of the global Development and Commercialization of the Licensed Products outside the Territory or to support its activities set forth on Schedule 2.8(b). Nothing in this Agreement shall be construed as a grant by Epizyme to any Hutchmed Entity of any right with respect to any companion diagnostic or complimentary diagnostic for use with Licensed Products; provided that the foregoing shall not prevent any Hutchmed Entity from exercising any of the rights granted hereunder for purposes of identifying or selecting patients for clinical trials or treatment with Licensed Products in the Field in accordance with this Agreement. Nothing in this Agreement shall be construed as a grant by Epizyme to any Hutchmed Entity of any right under any of Epizyme’s Patent Rights, Know-How or Confidential Information with respect to Hutchmed Dual Inhibitor Products.

Epizyme shall use Commercially Reasonable Efforts to ensure that the patient informed consent forms used by Epizyme and any other Epizyme Entity permit the transfer of patient information to Hutchmed; provided that, if despite the exercise of such Commercially Reasonable Efforts, such transfer is not permitted by the patient’s informed consent form, then Epizyme shall not be obligated to provide any such patient information or results to Hutchmed.

The information and documents provided by Epizyme under this Section 2.6(a) shall be in English. In the event Hutchmed requests that Epizyme provide novel data analysis or the generation of novel datasets that (A) cannot be performed by any Hutchmed Entity in the Territory and (B) is necessary for obtaining the Regulatory Approval for the Licensed Product in the Territory, then Epizyme shall conduct such work and Hutchmed shall reimburse Epizyme for such work at the FTE Rate within [**] after receipt of an invoice therefor.

The Hutchmed Product Data shall be considered Hutchmed’s Know-How and shall be subject to the licenses granted to Epizyme under Section 2.2 and the obligations of confidentiality and non-use under Article 10.

Hutchmed shall use Commercially Reasonable Efforts to ensure that any contract executed after the Effective Date between Hutchmed and any Third Party pertaining to the conduct by such Third Party of any Development activities for Licensed Product including clinical trials (including investigator-initiated trials) contains an obligation for such Third Party to provide the data resulting from such activity to Hutchmed with the right to transfer to Epizyme; provided that the Parties acknowledge that a transfer to Epizyme of data under a contract between Hutchmed and a Third Party for the provision of any materials (including Other Combination Drugs) from the Third Party for use in any Development activity for the Licensed Product shall be subject to any confidentiality restrictions imposed by the Third Party.

Notwithstanding the foregoing, Hutchmed shall not be obligated to provide to Epizyme any Hutchmed Product Data that consists of PHI to the extent providing such Hutchmed Product Data would violate HIPAA; to the extent Epizyme comes into possession of any PHI by or through Hutchmed under this Agreement in violation of HIPAA, Epizyme shall return such PHI to Hutchmed. Hutchmed shall use Commercially Reasonable Efforts to ensure that the patient informed consent forms used by Hutchmed and any other Hutchmed Entity permit the transfer of patient information to Epizyme; provided that, if despite the exercise of such Commercially Reasonable Efforts, such transfer is not permitted by the patient’s informed consent form, then Hutchmed shall not be obligated to provide any such patient information or results to Epizyme.

Specific Hutchmed Product Data that is provided to a Committee under this Agreement is not required to also be provided under this Section 2.6(b). In the event Epizyme requests that Hutchmed provide novel data analysis or the generation of novel datasets, and if Hutchmed agrees to conduct such work, then Epizyme shall reimburse Hutchmed for such work at the FTE Rate within [**] after receipt of an invoice therefor.

(c) Each Party shall ensure that, in the case of Hutchmed, the Hutchmed Product Data, and in the case of Epizyme, the Epizyme Product Data, will be provided to the other Party in compliance with all applicable local data privacy Laws and rules on cross-border data transmission, including the Cybersecurity Law of Mainland China, the Data Security Law of Mainland China, and relevant regulations or policies on protection of personal data, data privacy and cross-border transmission, as applicable.

2.7 In-License Agreements.

(a) Epizyme New In-License Agreements. Subject to Section 16.2, Epizyme shall be free to

26

 


 

 

negotiate with a Third Party for any agreement pursuant to which Epizyme would acquire or license in the Territory (or in and outside the Territory) any Patent Right or Know-How (which, for the purposes of Section 2.7, shall not include data which is covered by Section 2.6) of such Third Party that is necessary or reasonably useful for the Development, Manufacture, or Commercialization of any Licensed Compound or Licensed Product in the Field (“Third Party IP”). If Epizyme does not obtain the right to sublicense such Third Party IP to Hutchmed in the Territory, then Epizyme shall so notify Hutchmed and shall not enter into any agreement with respect to such Third Party IP that includes any grant of rights in the Field in the Territory. Epizyme will promptly provide Hutchmed with notice and a copy of any such executed Third Party agreement in which Epizyme has the right to sublicense Third Party IP to Hutchmed in the Territory (redacted as necessary to comply with any confidentiality obligations of Epizyme to such Third Party) and a schedule of all obligations that would be applicable to Hutchmed as a sublicensee under such Third Party IP. Within [**] following receipt of such notice, Hutchmed will decide, in its sole discretion, whether it will accept the applicable Third Party agreement as an Epizyme New In-License Agreement, and provide notice of such decision to Epizyme. For clarity, Epizyme shall not be obligated to acquire or license any Third Party IP in the Territory for any reason.

In the event that Hutchmed declines to accept such Third Party agreement as an Epizyme New In-License Agreement, then (i) such Third Party agreement shall not be deemed to be an “Epizyme New In-License Agreement” hereunder, (ii) Epizyme shall have no obligation to license or acquire rights to such Third Party IP in the Territory, and (iii) any rights to such Third Party IP in the Territory that are granted to Epizyme under such Third Party agreement will not be deemed to be “Controlled” by Epizyme or licensed to Hutchmed under this Agreement.

In the event that Hutchmed accepts such Third Party agreement as an Epizyme New In-License Agreement, then, upon effectiveness of such Third Party agreement, (A) such Third Party agreement will be included within the definition of “Epizyme New In-License Agreement,” (B) any rights to Third Party IP granted to Epizyme under such Epizyme New In-License Agreement will be deemed to be “Controlled” by Epizyme and sublicensed to Hutchmed in the Territory pursuant to the terms of this Agreement; (C) the sublicenses granted by Epizyme to Hutchmed in this Agreement will be subject to the terms of such Epizyme New In-License Agreement, to the extent described in the schedule provided by Epizyme to Hutchmed pursuant to the first paragraph of this Section 2.7(a), including the scope of the license granted to Epizyme or any Affiliate thereunder and the rights retained by such Third Party counterparties and any other Third Parties (including Governmental Authorities) set forth therein, and (D) Hutchmed shall reimburse [**] percent ([**]%) of the amounts payable to the Third Party arising from and allocable to the exercise of rights by a Hutchmed Entity under such Epizyme New In-License Agreement and after the application of all available discounts, reductions, and offsets available under such Epizyme New In-License Agreement. Without limiting the foregoing, if any Epizyme New In-License Agreement provides for tiered royalty rates based on sales of the applicable products or therapies, then the royalty payments subject to reimbursement by Hutchmed shall be determined by allocating the royalty-bearing sales by Hutchmed in proportion to Hutchmed’s and Epizyme’s (and their respective Affiliates’ and (sub)licensees’) total royalty-bearing sales.

Hutchmed acknowledges and agrees that certain of the rights, licenses and sublicenses granted by Epizyme to Hutchmed in this Agreement (including any sublicense rights) are subject to the terms of the Epizyme In-License Agreements, including the Eisai Agreement, and the rights granted to the Third Party counterparties thereunder, the scope of the licenses granted to Epizyme or any applicable Affiliate thereunder and the rights retained by such Third Party counterparties and any other Third Parties (including Governmental Authorities) set forth therein. Hutchmed shall, and shall ensure that each Hutchmed Entity shall, perform and take such actions to allow Epizyme and its Affiliates to comply with their obligations under each Epizyme In-License Agreement, to the extent applicable to Hutchmed’s rights or obligations under this Agreement and to the extent set forth in Schedule 2.7(a) (with respect to the Eisai Agreement)

27

 


 

 

or as set forth in the schedule provided by Epizyme to Hutchmed pursuant to the first paragraph of this Section 2.7(a). Without limiting the foregoing, each Hutchmed Entity shall prepare and deliver to Epizyme, or assist Epizyme in preparing, any additional reports required under any Epizyme In-License Agreement, in each case reasonably sufficiently in advance to enable Epizyme and its Affiliates to comply with their obligations thereunder.

(b) Hutchmed In-License Agreements. Subject to Section 16.2, Hutchmed shall be free to negotiate with any Third Party for any agreement pursuant to which Hutchmed would acquire or license Third Party IP in the Territory (or in and outside the Territory). If Hutchmed does not obtain the right to sublicense such Third Party IP to Epizyme outside the Territory, then Hutchmed shall so notify Epizyme and shall not enter into any agreement with respect to such Third Party IP that includes any grant of rights in the Field outside the Territory. Hutchmed will promptly provide Epizyme with notice and a copy of any such executed Third Party agreement in which Hutchmed has the right to sublicense Third Party IP to Epizyme outside the Territory (redacted as necessary to comply with any confidentiality obligations of Hutchmed to such Third Party) and a schedule of all obligations that would be applicable to Epizyme as a sublicensee under such Third Party IP. Within [**] following receipt of such notice, Epizyme will decide, in its sole discretion, whether it will accept the applicable Third Party agreement as a Hutchmed In-License Agreement, and provide notice of such decision to Hutchmed. For clarity, Hutchmed shall not be obligated to acquire or license any Third Party IP outside the Territory for any reason.

In the event that Epizyme declines to accept such Third Party agreement as a Hutchmed In-License Agreement, then (i) such Third Party agreement shall not be deemed to be a “Hutchmed In-License Agreement” hereunder, (ii) Hutchmed shall have no obligation to license or acquire rights to such Third Party IP outside the Territory, and (iii) any rights to such Third Party IP outside the Territory that are granted to Hutchmed under such Third Party agreement will not be deemed to be “Controlled” by Hutchmed or licensed to Epizyme under this Agreement.

In the event that Epizyme accepts such Third Party agreement as a Hutchmed In-License Agreement, then, upon effectiveness of such Third Party agreement, (A) such Third Party agreement will be included within the definition of “Hutchmed In-License Agreement,” (B) any rights to Third Party IP granted to Hutchmed under such Hutchmed In-License Agreement will be deemed to be “Controlled” by Hutchmed and sublicensed to Epizyme outside the Territory pursuant to the terms of this Agreement; (C) the sublicenses granted by Hutchmed to Epizyme in this Agreement will be subject to the terms of such Hutchmed In-License Agreement, to the extent described in the schedule provided by Hutchmed to Epizyme pursuant to the first paragraph of this Section 2.7(b) including the scope of the license granted to Hutchmed or any Affiliate thereunder and the rights retained by such Third Party counterparties and any other Third Parties (including Governmental Authorities) set forth therein, and (D) Epizyme shall reimburse [**] percent ([**]%) of the amounts payable to the Third Party arising from and allocable to the exercise of rights by a Epizyme Entity under such Hutchmed In-License Agreement and after the application of all available discounts, reductions, and offsets available under such Hutchmed In-License Agreement. Without limiting the foregoing, if any Hutchmed In-License Agreement provides for tiered royalty rates based on sales of the applicable products or therapies, then the royalty payments subject to reimbursement by Epizyme shall be determined by allocating the royalty-bearing sales by Epizyme in proportion to Hutchmed’s and Epizyme’s (and their respective Affiliates’ and (sub)licensees’) total royalty-bearing sales.

Epizyme acknowledges and agrees that certain of the rights, licenses and sublicenses granted by Hutchmed to Epizyme in this Agreement (including any sublicense rights) may be subject to the terms of the Hutchmed In-License Agreements, and the rights granted to the Third Party counterparties thereunder, the scope of the licenses granted to Hutchmed or any applicable Affiliate thereunder and the rights retained by such Third Party counterparties and any other Third Parties (including Governmental Authorities) set forth therein. Epizyme shall, and shall ensure that each Epizyme Entity shall, perform and take such actions

28

 


 

 

to allow Hutchmed and its Affiliates to comply with their obligations under each Hutchmed In-License Agreement, to the extent applicable to Epizyme’s rights or obligations under this Agreement or as set forth in the schedule provided by Hutchmed to Epizyme pursuant to the first paragraph of this Section 2.7(b). Without limiting the foregoing, each Epizyme Entity shall prepare and deliver to Hutchmed, or assist Hutchmed in preparing, any additional reports required under any Hutchmed In-License Agreement, in each case reasonably sufficiently in advance to enable Hutchmed and its Affiliates to comply with their obligations thereunder.

Combination Drug (including any Hutchmed Compound) that is proposed by Hutchmed that is reasonable from a safety and potential efficacy perspective in the Territory, and (B) with respect to any Other Combination Drugs proposed by Epizyme, Hutchmed may (1) reject the use of any Hutchmed Compound in any Joint Combination Therapy if Hutchmed reasonably and in good faith determines that the use of such Hutchmed Compound in the Development or Commercialization of such Joint Combination Therapy is not commercially reasonable or would lead to a safety issue for the Hutchmed Compound or Joint Combination Therapy, or (2) reject and not be obligated to pursue the Development or Commercialization in the Territory of an Epizyme Combination Therapy proposed by Epizyme (even if approved by Epizyme) if Hutchmed reasonably and in good faith determines that pursuing the Development or Commercialization of such Epizyme Combination Therapy in the Territory is not commercially reasonable or would lead to a safety issue for the Licensed Product or Epizyme Combination Therapy in the Territory (any such rejected Combination Therapy, a “Rejected Combination Therapy”); and

(iii) any matter related to the Manufacture of Licensed Products for use in the Territory or outside the Territory and any matter to be determined or approved by the JMC that is not resolved under Section 3.10(a)(iv) (including the approval of any Permitted Subcontractor CMO, if any, under Section 3.5(f), and the approval of the CMC module under Section 3.5(g)), except that (A) Epizyme shall not use its final decision-making authority to require Hutchmed to accept any new Dosage Form Change, and (B) Epizyme shall not use its final decision-making authority to take any action contrary to the terms of the Clinical Supply Agreement, Commercial Supply Agreement, or Manufacturing Technology Transfer Agreement executed by the Parties.

For clarity, Epizyme shall have final decision-making authority regarding whether to conduct a Joint Global Trial proposed by Hutchmed, the conduct of any clinical trial outside of the Territory, the study design of any Joint Global Trial or any clinical trial outside of the Territory, and the budget under Section 9.3(c)(iii). Notwithstanding the foregoing, in no event shall Epizyme use its decision-making authority to increase the number of patients to be enrolled and treated by Hutchmed in any Joint Global Trial to greater than twenty percent (20%) of the total number of patients to be treated at all sites globally.

Any decision made by a Party in accordance with this Section 3.10 shall be deemed to be a decision of the relevant Committee.

3.11 Limitations on Decision-Making.

(a) Neither Party shall have the deciding vote on, and no Committee shall have decision-making authority regarding, any of the following matters: (i) the imposition of any requirements on the other Party to undertake increased costs or obligations, or to forgo any of its rights, under this Agreement; (ii) the imposition of any requirements that the other Party takes or declines to take any action that would result in a violation of any Applicable Law or any agreement with any Third Party or the infringement of intellectual property rights of any Third Party; (iii) the resolution of a dispute involving the breach or alleged breach of this Agreement; (iv) the determination of whether a Hutchmed Entity exerts Commercially Reasonable Efforts under this Agreement; (v) any decision that is expressly stated to require the mutual agreement (or similar language) of a Committee or the Parties or the approval of the other Party (but not “approval” of a Committee); (vi) any matters that would excuse such Party from any of its obligations under, or waive any term of, this Agreement; or (vii) modifying the terms of this Agreement or taking any action to expand or narrow the responsibilities of any Committee. In no event may the decision-making Party unilaterally determine that it has fulfilled any obligations hereunder or that the non-deciding Party has breached any obligations hereunder. In no event may Hutchmed unilaterally determine that any events required for the

36

 


 

 

payment of milestone payments have not occurred and in no event may Epizyme unilaterally determine that the events required for the payment of milestone payments have occurred.

(b) In no event shall Hutchmed exercise its final decision-making authority with respect to the Licensed Products in the Territory in a manner that Epizyme has notified Hutchmed (including through the applicable Committee or Subcommittee) is reasonably expected to have a material adverse effect on the Manufacturing, Development or Commercialization for any Licensed Product outside the Territory, or scope, validity or enforceability of any Licensed IP. In no event shall Epizyme exercise its final decision-making authority with respect to the Licensed Products outside the Territory in a manner that Hutchmed has notified Epizyme (including through the applicable Committee or Subcommittee) is reasonably expected to have a material adverse effect on the Development or Commercialization of any Licensed Product in the Territory.

For clarity, approval by a Committee shall not be understood to mean approval by a Party.

3.12 Scope of Governance. Notwithstanding the creation of each of the Committees or anything to the contrary in this Article 3, each Party shall retain the rights, powers and discretion granted to it under this Agreement, and no Committee shall be delegated or vested with rights, powers or discretion unless such delegation or vesting is expressly provided herein, or the Parties expressly so agree in writing. It is understood and agreed that issues to be formally decided by a particular Committee are only those specific issues that are expressly provided in this Agreement to be decided by such Committee, as applicable. For clarity, no Committee shall have any rights, powers or discretion to make any decision regarding the Development, Manufacturing or Commercialization of the Licensed Products outside of the Field or outside of the Territory, and, with respect to such matters relating to Licensed Products that are so excluded from the Committees’ scope of authority, Epizyme retains all such rights, powers and discretion.

3.13 Alliance Managers. Each of the Parties shall appoint a single individual to manage Development, Manufacturing and Commercialization obligations between the Parties under this Agreement (each, an “Alliance Manager”). The role of the Alliance Manager is to act as a single point of contact between the Parties to ensure a successful relationship under this Agreement. The Alliance Managers may attend any Committee and Subcommittee meetings. Each Alliance Manager shall be a non-voting participant in such Committee and Subcommittee meetings, unless s/he is also appointed a member of such Committee; provided, however, that an Alliance Manager may bring any matter to the attention of a Committee if such Alliance Manager reasonably believes that such matter warrants such attention. Each Party may change its designated Alliance Manager at any time upon written notice to the other Party. Any Alliance Manager may designate a substitute to temporarily perform the functions of that Alliance Manager by written notice to the other Party. Each Party’s Alliance Manager and any substitute for an Alliance Manager shall be bound by obligations of confidentiality and non-use applicable to the other Party’s Confidential Information that are at least as stringent as those set forth in Article 10. Each Alliance Manager will also: (a) plan and coordinate cooperative efforts and internal and external communications; and (b) facilitate the governance activities hereunder and the fulfillment of action items resulting from Committee meetings.

Article 4. LICENSED PRODUCT DEVELOPMENT

4.1 Development in the Field in the Territory. The Development of Licensed Products in the Field in the Territory shall be governed by the Clinical Development Plan, and no Hutchmed Entity may Develop any Licensed Product in the Field in the Territory other than in accordance with the Clinical Development Plan or as otherwise approved by the JDC in advance. Hutchmed shall use Commercially Reasonable Efforts to execute and to perform, or cause to be performed, the activities assigned to it in the Clinical Development Plan, in each case in accordance with the terms of this Agreement including Section 4.4. Hutchmed shall use Commercially Reasonable Efforts to Develop Licensed Products in the Territory for

37

 


 

 

each Initial Indication and any Additional Indication (other than a Rejected Additional Indication). Hutchmed will use Commercially Reasonable Efforts to identify Hutchmed Compounds (including those listed on Schedule 1.91) to combine with Licensed Products as potential Joint Combination Therapies in the Territory, and propose such Hutchmed Compounds to the JDC in accordance with Section 4.3(b).

4.2 Clinical Development Plan. The Parties shall ensure at all times that the Clinical Development Plan (a) is consistent with the terms and conditions of this Agreement, (b) is focused on efficiently obtaining Regulatory Approval for Licensed Products (whether as a monotherapy or as part of a Combination Therapy) in each Initial Indication and Additional Indication (other than a Rejected Additional Indication) in the Territory, (c) does not include activities that could reasonably be expected to have a material adverse effect on the Development, Manufacture or Commercialization of Licensed Compound or Licensed Products outside of the Territory; and (d) does not include activities that constitute or potentially constitute a violation of the requirements set out in Applicable Law in the Territory.

The Clinical Development Plan shall provide a summary of each bridging study, Local Trial, Joint Global Trial, investigator sponsored trial and registry study to be conducted any Hutchmed Entity in the Territory, including in reasonable detail (i) all material Development activities reasonably anticipated to be undertaken by the Hutchmed Entities or Hutchmed Entities and Epizyme Entities, (ii) the endpoints for all clinical trials contemplated by such plan, (iii) identification of the clinical trials that are intended to be a Pivotal Trials, (iv) all material regulatory activities and Regulatory Authority interactions anticipated to be conducted by the Hutchmed Entities in support of Regulatory Approval of the Licensed Products in the Field in the Territory, including all planned material Regulatory Filings to be submitted in connection with such approvals, and (v) the budget for Hutchmed’s share of costs associated with participation in Joint Global Trials in accordance with Section 9.3(c)(iii). Each Party shall be responsible for determining the budget for its activities in its respective territory for Joint Global Trials.

4.3 CDP Updates. Either Party may propose to the JDC that the Clinical Development Plan be updated, including:

(a) that a Licensed Product be Developed, Manufactured and Commercialized in the Territory for an indication other than the Initial Indications or any previously-approved Additional Indication. In the event any such additional indication is proposed by a Party, then the JDC shall determine whether to approve such additional indication for inclusion in the Clinical Development Plan (any such approved additional indication, an “Additional Indication”); provided that, for clarity, an Additional Indication in the Territory shall not include any Rejected Additional Indication pursuant to Section 3.10(b)(i);

(b) that a Licensed Product be Developed, Manufactured and Commercialized in the Territory as part of a Combination Therapy (in addition to the Combination Therapies that are being studied as part of the 301 Global Trial and 302 Global Trial or any previously approved Combination Therapy), including that a Hutchmed Compound be part of a potential Joint Combination Therapy in the Territory; provided that, for clarity, a Combination Therapy in the Territory shall not include any Rejected Combination Therapy pursuant to Section 3.10(b)(ii); or

(c) that one or more Local Trials be conducted in the Territory or Joint Global Trials be conducted globally (with clinical sites in the Territory).

Any proposal by either Party to the JDC shall include sufficient information for the other Party to assess the proposal and shall include, at a minimum, the scientific rationale for the proposed Development activity and an overview of the plan to accomplish such Development activity, including the Development and Regulatory Approval strategy, timelines, relevant competitive landscape, epidemiology, Manufacturing requirement, and pre-clinical activities, if any.

38

 


 

 

Notwithstanding any other provision of this Agreement, neither Party shall be obligated to propose any clinical trial or Development activity for any Licensed Product (including any Combination Therapy) for any indication to the JDC for inclusion in the Clinical Development Plan, and Epizyme shall be free at its discretion, itself or with Third Parties, to perform any clinical trial of, or otherwise Develop, any Licensed Product or Combination Therapy in any indication in one or more countries outside of the Territory, including any Epizyme Trial.

At least [**], the JDC shall review and update the Clinical Development Plan. Each Party may submit to the JDC from time to time proposed amendments to the Clinical Development Plan. The JDC shall review and may approve such proposed amendments or any other proposed amendments that the JDC may consider from time to time in its discretion and, upon any such approval by the JDC, the Clinical Development Plan shall be amended accordingly (and a copy of any such updated Clinical Development Plan shall be provided to each Party and shall be attached to the minutes of the next meeting, but shall not require an amendment to this Agreement).

4.4 Conduct of Local Trials. Hutchmed may conduct Local Trials of the Licensed Product (including, subject to Section 3.10(b)(ii), any Combination Therapy) in the Field (including, subject to Section 3.10(b)(i), any Additional Indication) and in the Territory. Each Local Trial conducted in the Territory shall be conducted in accordance with the Clinical Development Plan, the study protocol approved by the JDC and any relevant Regulatory Authority, and Applicable Law in the Territory. Hutchmed shall be solely responsible for its performance in the Territory (including handling relevant Regulatory Filings for any Local Trials in the Territory at its own cost, as applicable, in accordance with Article 5). Unless prohibited by Applicable Law, Hutchmed, itself or with or through any other Hutchmed Entity, shall be the CTA owner or Authorized Regulatory Agent of each Local Trial, as determined by Hutchmed in its sole discretion. For each Local Trial, Hutchmed shall provide Epizyme with a synopsis of each clinical trial protocol and specific sections of the protocol as reasonably requested by Epizyme, in English.

Hutchmed will be responsible for ensuring that all informed consent forms for use in the Territory in any Local Trial: (i) allow Hutchmed to provide Epizyme and its Affiliates with access to and use of data and samples generated or obtained in such trials (and in no event less than the same use rights granted to Hutchmed and with respect to samples to the extent permitted by Applicable Law), and (ii) comply with Applicable Law.

4.5 Conduct of Joint Global Trials.

(a) Potential Global Clinical Trials. Epizyme may present any potential clinical trial of the Licensed Product that includes clinical sites both in the Territory and outside the Territory, along with the plan for such global study, to Hutchmed via the JDC. Hutchmed may also present a potential global study of the Licensed Product to the JDC. The JDC shall discuss and decide in good faith whether the Parties will conduct such trial as a Joint Global Trial, subject to Epizyme’s final decision-making authority under Section 3.10(b); provided that Hutchmed shall have final decision-making authority regarding whether to participate in any such global study as provided in Section 3.10(a)(ii).

(b) Obligations of the Parties. The Parties will be responsible for the performance of any Joint Global Trial as determined by the JDC. The conduct of any Joint Global Trial in the Territory shall be in accordance with the Clinical Development Plan, Epizyme’s study protocol (approved by any relevant Regulatory Authority), and Applicable Law in the Territory. Unless otherwise agreed by the Parties, for the 301 Global Trial, 302 Global Trial and any other Joint Global Trial, and subject to the other provisions in this Section 4.5, Epizyme shall, either by itself or through a Third Party contract research organization (the “Epizyme CRO”), at Epizyme’s sole cost and expense (subject to Section 9.3(c)(iii)), provide oversight of the clinical trial operations in the Territory to ensure consistency with the clinical trial

39

 


 

 

operations outside the Territory. The JDC shall determine the timing of the inclusion of clinical sites in the Territory for each Joint Global Trial, with the understanding that Hutchmed will identify and manage clinical sites in the Territory for any relevant Joint Global Trials. A copy of all clinical trial related documents for each Joint Global Trial, including protocols, informed consent forms, and safety data shall be provided to Epizyme in the language in which they were drafted; any such documents that are not received in English will be translated into English at Epizyme’s request by the Epizyme CRO, at Epizyme’s cost. Unless prohibited by Applicable Law, Hutchmed, itself or with or through any other Hutchmed Entity, shall be the Authorized Regulatory Agent of each Joint Global Trial in the Territory. Hutchmed will be responsible for ensuring that all informed consent forms for use in the Territory in any Joint Global Trial: (i) allow Hutchmed to provide Epizyme and its Affiliates with access to and use of data and samples generated or obtained in such trials (and in no event less than the same use rights granted to Hutchmed and with respect to samples to the extent permitted by Applicable Law), and (ii) comply with Applicable Law.

(c) Hutchmed Minimum Patient Obligation. Hutchmed shall use Commercially Reasonable Efforts, either by itself, through any Hutchmed Entity or through the Epizyme CRO, to recruit, enroll, treat, and provide follow-up in a timely manner of twenty percent (20%) of the total number of patients to be treated under the protocol approved by the FDA and NMPA (or such increased or decreased total number of patients as may be required by a Regulatory Authority inside or outside the Territory) for the 301 Global Trial, the 302 Global Trial, and any other Joint Global Trial; provided that a Hutchmed Entity shall not enroll any patients in any clinical trial, and shall not be in breach of this Agreement for not having enrolled any such patients (so long as Hutchmed is using Commercially Reasonable Efforts to pass an in-person quality audit), until Hutchmed has passed, to Epizyme’s reasonable satisfaction, an in-person quality audit conducted by Epizyme or its designee. For clarity, once Hutchmed has passed such quality audit, then the proviso in the foregoing sentence shall not apply to any subsequent Joint Global Trial.

(d) 302 Global Trial. Notwithstanding anything to the contrary in this Agreement, in the event that the Regulatory Authorities in Mainland China determine that the 302 Global Trial cannot be used as the confirmatory trial for a conditional Regulatory Approval of the Licensed Product as a monotherapy to treat relapsed/refractory FL, then Hutchmed shall provide Epizyme with a copy of all Regulatory Documents relating to such determination by the Regulatory Authority (in English) and Hutchmed shall continue to use Commercially Reasonable Efforts to conduct the 302 Global Trial in compliance with Section 4.5(c), except (i) Epizyme shall reimburse Hutchmed for all internal and Out-of-Pocket Costs incurred by Hutchmed Entities to enroll and treat such patients in the 302 Global Trial in the Territory after such notice in accordance with, and not in excess of, the budget proposed by Hutchmed for the 302 Global Trial in the Territory as discussed at the JDC in accordance with Section 3.3(h), and (ii) the 302 Global Trial shall be a Rejected Global Trial for the purposes of Sections 9.3(d) and 14.7(c), and shall remain a Joint Global Trial for all other purposes.

(e) 301 Global Trial. Notwithstanding anything to the contrary in this Agreement, in the event Epizyme determines, after consultation with the FDA, to discontinue the 301 Global Trial outside the Territory, then (i) the 301 Global Trial shall no longer be a Joint Global Trial and Hutchmed shall no longer be obligated to participate in such clinical trial, and (ii) ES shall no longer be an Initial Indication for purposes of this Agreement.

4.6 Conduct of Rejected Global Trials. Epizyme may, itself or with or through any other Epizyme Entity, perform any Rejected Global Trial and include one or more clinical sites in the Territory; provided that the Parties shall discuss the inclusion of clinical sites in the Territory in such Rejected Global Trial and Epizyme shall reasonably consider any concerns raised by Hutchmed about the use of such clinical sites. Epizyme shall use Hutchmed as a contract research organization in the Territory for such Rejected Global Trial (so long as the costs of using Hutchmed are not greater than the costs a reputable Third Party contract research organization would charge Epizyme for such work), unless Hutchmed notifies Epizyme that

40

 


 

 

Hutchmed does not agree to serve as the contract research organization for such Rejected Global Trial, in which case Epizyme may use any Third Party as a contract research organization. The Parties agree that Section 9.3(d) shall apply with respect to such Rejected Global Trial.

4.7 Samples. To the extent permissible under Applicable Law, Epizyme or its designee shall own all biological samples obtained in connection with any Joint Global Trial, and, at Epizyme’s request, Hutchmed shall transfer to Epizyme or its designee a reasonable quantity as mutually agreed of any such biological samples in Hutchmed’s possession or control. If Applicable Law prohibits such ownership or transfer, the Parties will work together to provide Epizyme or its designee with rights and access to such biological samples as close to those described in the preceding sentence as is permitted by Applicable Law.

4.8 Meetings. Hutchmed may hold meetings with investigators engaged in clinical trials of Licensed Products in the Territory and advisory board meetings to discuss the Development of Licensed Products in the Territory, all as appropriate and compliant with Applicable Law including Anti-Corruption Law. To the extent practicable and permissible by Applicable Law and Regulatory Authorities, Hutchmed shall use good faith efforts to accommodate Epizyme so that Epizyme may have up to [**] employees or other representatives (who are bound by written obligations of nondisclosure and non-use no less stringent than those set forth in Article 10) participate at any material meetings with such investigators in the Territory; provided that any exercise of such right by Epizyme shall not require Hutchmed to delay the Development or Commercialization of the Licensed Product, including in arranging any such meeting or delaying in responding to such investigators. Hutchmed shall provide Epizyme with reasonable notice prior to any such meetings.

4.9 Conferences and Key Opinion Leaders. As commercially reasonable and in compliance with Applicable Law including Anti-Corruption Laws, Hutchmed (a) shall attend and have the right to lead the presence of the Parties at Territory-specific conference or congresses relevant to the Licensed Product in the Territory, (b) may attend international conferences or congresses relevant to the Licensed Product outside the Territory; provided, that Epizyme shall be responsible for leading the presence of the Parties at any such conference or congress, (c) shall be responsible for establishing appropriate relationships with key opinion leaders who are within the Territory, and (d) shall provide Epizyme with an update of its attendance at any conference or congress and of any key opinion leaders met. Epizyme may attend conferences or congresses in the Territory, at its option; provided, however, that Hutchmed shall be responsible for leading the presence of the Parties at any Territory-specific conference or congress, and Epizyme shall be responsible for leading the presence of the Parties at any international conference or congress in the Territory.

4.10 Development Updates. In addition to the transfer of Hutchmed Product Data under Section 2.6(b), at each meeting of the JDC in each [**], Hutchmed shall provide the JDC with a summary of the Development activities for the Licensed Products in the Field in the Territory (including a clinical trial operational update) performed by the Hutchmed Entities in the Calendar Quarter prior to such meeting of the JDC. Within [**] after the end of each Calendar Year, Hutchmed shall provide Epizyme with a written report that updates the previous [**] report provided to Epizyme and that details the Development activities for the Licensed Product in the Field in the Territory. In addition, Hutchmed shall provide a prompt written notice to Epizyme of any clinical holds, Regulatory Filings, Regulatory Approvals and clinical trial initiation or completion, in each case, in the Field in the Territory, which notice shall be not later than [**] with respect to clinical holds, Regulatory Filings and Regulatory Approvals and not later than [**] with respect to any other events such as clinical trial initiation or completion.

4.11 Pre-Clinical Research. Hutchmed, itself or through other Hutchmed Entities, shall conduct any Pre-Clinical Research in the Territory in relation to Licensed Products solely to support clinical Development

41

 


 

 

of Licensed Products, in accordance with the Clinical Development Plan and as determined by the JDC. Hutchmed shall bear all costs related to such Pre-Clinical Research activities.

4.12 Standards of Conduct. The Hutchmed Entities shall perform all Development activities under the Clinical Development Plan (a) in a good scientific manner, (b) in accordance with all applicable GLP, GVP, GCP, and all applicable local regulations promulgated or endorsed by any applicable Regulatory Authority in the Territory, or as otherwise specified in the Clinical Development Plan, (c) in accordance with the quality plan agreed upon by the Parties to verify Hutchmed’s GxP compliance, and (d) in compliance in all material respects with Applicable Laws.

4.13 Records. The Hutchmed Entities shall maintain written or electronic records in sufficient detail, in a good scientific manner (in accordance with all applicable GLP, GVP and GCP promulgated or endorsed by any applicable Regulatory Authority in the Territory, or as otherwise specified in the Clinical Development Plan) and appropriate for regulatory and patent purposes, which are complete and accurate in all material respects and reflect all material Development work performed under the Clinical Development Plan. Epizyme shall have the right, upon reasonable advance notice, and no more than [**], to inspect and copy all such records (for clarity, including all applicable clinical, regulatory and quality records).

Article 5. LICENSED PRODUCT REGULATORY OBLIGATIONS

5.1 Hutchmed Responsibility. Other than the CTA for the 302 Global Trial (which was filed by Epizyme with the Regulatory Authorities in Mainland China and Taiwan prior to the Effective Date), and subject to Sections 3.10(a) and 4.1, Hutchmed shall use Commercially Reasonable Efforts to prepare Regulatory Filings and obtain (or cause to be obtained) and maintain Regulatory Approval and, if applicable, Reimbursement Approval, for a Licensed Product in each Initial Indication and Additional Indication in each of (i) Mainland China, (ii) Taiwan and (iii) Hong Kong and Macau (with it being agreed that, if Regulatory Approval is obtained in Hong Kong, Hutchmed shall not also be required to separately obtain Regulatory Approval in Macau, or vice versa) at Hutchmed’s expense; provided that all IND or Drug Approval Applications for any Licensed Product in the Territory shall be filed only after approval by the JDC.

Upon request by Epizyme, Hutchmed shall provide a signed statement to this effect in accordance with 21 C.F.R. §314.50(g)(3) or any non-U.S. counterpart to such regulation.

(c) Regulatory Liaisons. Promptly (but in no event later than [**]) following the Effective Date, the Parties shall each designate an employee with responsibility for regulatory activities to consult with the other Party’s representative with respect to the transfer of Regulatory Documents between the Parties (such representatives, the “Regulatory Liaisons”). The Regulatory Liaisons shall discuss and provide input to each other, at such times, places and frequencies as mutually agreed, on all material issues with respect to the sharing and transfer of Regulatory Documents; provided that all final decisions related to Regulatory Filings and Regulatory Approvals shall be made by the Party with the right to control such decision as set forth in Section 3.10.

5.3 Ownership of Regulatory Filings and Approvals. Epizyme shall transfer to Hutchmed the CTA for the 302 Global Trial in Mainland China and Taiwan as soon as practicable after the Effective Date. All Regulatory Filings and resulting Regulatory Approvals for Licensed Product in the Territory (and all corresponding applications for marketing or regulatory exclusivity) shall be applied for in the name of and exclusively owned by Hutchmed. If at the time of a Regulatory Filing, the Regulatory Authorities and Applicable Law in the Territory prohibit Hutchmed from filing and owning such Regulatory Filings and Regulatory Approvals in the Territory, then (a) all such Regulatory Filings and Regulatory Approvals shall

43

 


 

 

be applied for by Hutchmed in the name of and exclusively owned by Epizyme with Epizyme appointing Hutchmed and Hutchmed acting as Epizyme’s sole Authorized Regulatory Agent, and (b) Epizyme will cooperate with Hutchmed, and provide necessary assistance to Hutchmed, to transfer such Regulatory Filings and Regulatory Approvals to Hutchmed at such time as Applicable Law no longer prohibits Hutchmed from filing and owning such Regulatory Filings and Regulatory Approvals in the Territory; provided that upon termination (but not expiration) of this Agreement for any reason all such Regulatory Filings and Regulatory Approvals will revert to the exclusive ownership of Epizyme, at no cost to Epizyme, and Hutchmed shall be obligated to take all actions and execute all documents as required by the Regulatory authority under Applicable Law to effect the transfer of such Regulatory Filings and Regulatory Approvals to Epizyme. All Regulatory Filings for any Rejected Global Trial that includes clinical sites in the Territory, if any, for the Development of Licensed Product in the Territory shall be applied for by Epizyme in the name of and exclusively owned by Epizyme unless and until Hutchmed makes a Buy-In Right Payment with respect to such Rejected Global Trial in which case the rest of this Section 5.3 will apply to such Regulatory Filings.

5.4 Meetings with Regulatory Authorities. To the extent practicable and permissible by Applicable Law and Regulatory Authorities, Hutchmed shall use good faith efforts to accommodate Epizyme so that Epizyme may have up to [**] employees or other representatives (who are bound by written obligations of nondisclosure and non-use no less stringent than those set forth in Article 10) participate at any material meetings with Regulatory Authorities in the Territory to discuss the Development or Commercialization of Licensed Products; provided that any exercise of such right by Epizyme shall not require Hutchmed to delay the Development or Commercialization of the Licensed Product, including by delaying in responding to Regulatory Authorities or in arranging any such meeting. Hutchmed shall provide Epizyme with reasonable notice prior to any such meetings.

5.5 Adverse Drug Events. Upon the earlier of [**] after the Effective Date or the date the first patient is enrolled into the first clinical trial of the Licensed Product in the Territory, the Parties shall enter into the Safety Data Exchange Agreement. Such Safety Data Exchange Agreement shall provide for Epizyme to hold and control, subject to Section 9.3(c)(iii), the global safety database for Tazemetostat and for the exchange by the Parties in English of any information of which a Party becomes aware concerning any adverse event experienced by a subject or patient being administered Tazemetostat, whether or not such adverse event is determined to be attributable to Tazemetostat, including any such information received by either Party from any Third Party (subject to receipt of any required consents from such Third Party). It is understood that each Party and, in the case of Epizyme, the Epizyme Entities, and, in the case of Hutchmed, the Hutchmed Entities, shall have the right to disclose such information if such disclosure is reasonably necessary to comply with Applicable Laws or requirements of any applicable Regulatory Authority.

Hutchmed Entities shall not use any quantity of Drug Product supplied by Epizyme for any purpose other than Commercialization in the Field and Territory in accordance with the Commercialization Plan and the terms of this Agreement, and Epizyme shall not be obligated under the Commercial Supply Agreement to supply quantities of Drug Product in excess of the forecasted quantity that Hutchmed notifies Epizyme, and Epizyme reasonably agrees, is needed to perform the Commercialization activities in the Territory. In addition, in no event shall Epizyme supply to Hutchmed under the Commercial Supply Agreement any quantity of Drug Product co-formulated with an Other Combination Drug. For any quantity of Drug Product supplied by Epizyme to Hutchmed for purposes of Commercialization of Licensed Products in the Field in the Territory, Hutchmed shall pay to Epizyme the Commercial Supply Price for such quantity, payable within [**] after receipt of an invoice therefor.

7.4 Other Manufacturing Activities and Costs.

(a) CMC Section Filings. Upon written request of Hutchmed, Epizyme shall reasonably support the development of data or information for the submission of the CMC section of any Regulatory Filing in the Territory under Article 5, and Hutchmed shall pay Epizyme the Manufacturing Activity Cost associated with such support within [**] after receipt of any invoice therefor.

(b) Process Development. Epizyme may (in its discretion) or shall (as mutually agreed by the Parties or required by any Regulatory Authority), perform or support the development and implementation of (i) a new dosage, form, or formulation changes for any Licensed Product (each, a “Dosage Form Change”), or (ii) process development, process improvement, manufacturing lifecycle management, or other Manufacturing activities to improve the yield, efficiency, or proprietary nature of the Manufacturing process for any Licensed Product (each, a “Manufacturing Improvement” and, along with a Dosage Form Change, individually and collectively referred to as a “Manufacturing Activity”).

As more fully described in the Clinical Supply Agreement, Commercial Supply Agreement, and Manufacturing Technology Transfer Agreement, in the event Epizyme undertakes any Manufacturing Activity in its discretion, as mutually agreed, or as required by any Regulatory Authority in the Territory, and it results in a Dosage Form Change or Manufacturing Improvement, then such Dosage Form Change or Manufacturing Improvement, as applicable shall automatically be included within the Epizyme Manufacturing Know-How. If such Manufacturing Activity was developed at Hutchmed’s request or required by a Regulatory Authority only for the Territory, then Hutchmed shall pay the full Manufacturing Activity Costs associated therewith; provided, however, that if such Manufacturing Activity has applicability for Licensed Products outside the Territory, then Hutchmed shall only be obligated to pay the portion of the Manufacturing Activity Costs associated therewith as reasonably allocated to jurisdictions outside the Territory on a proportionate basis. In addition to the Clinical Supply Price and Commercial Supply Price payments, Hutchmed shall pay to Epizyme any Manufacturing Activity Costs due and payable under this Section on a [**] basis, within [**] of receipt of an invoice therefor.

7.5 Epizyme Supply Chain Security Requirements. Hutchmed commits to refrain, and to use Commercially Reasonable Efforts to cause each Hutchmed Entity to refrain, from selling Licensed Product to unauthorized Third Parties or end users under Trade Control Laws such as any military and law enforcement parties of comprehensively Sanctioned Countries, including military hospitals where prohibited by applicable Trade Control Laws. Hutchmed shall perform this Agreement in the Territory in

49

 


 

 

compliance with Trade Control Laws as defined herein and within the limits set forth by any applicable OFAC Authorization. Hutchmed acknowledges and will use Commercially Reasonable Efforts to ensure that any Hutchmed Entity shall comply in connection herewith with Trade Control Laws and the scope of any applicable OFAC Authorization. Hutchmed shall use Commercially Reasonable Efforts to ensure that this duty to comply with such Trade Control Laws and the prohibitions or restrictions it involves will be reflected in the agreement to be entered into by Hutchmed and each Hutchmed Entity. Such OFAC Authorization or Trade Control Laws may restrict the selling of Licensed Products to specific Third Parties as mentioned therein. While storing, handling or distributing the Licensed Products, Hutchmed Entities shall make all reasonable efforts to comply with Epizyme supply chain security requirements set forth in Schedule 7.5 attached hereto, as may be amended by Epizyme from time to time, in order in particular to verify the security and integrity of the Licensed Products through all points of the supply chain. Hutchmed shall also use Commercially Reasonable Efforts to ensure that any Permitted Subcontractors used by Hutchmed in the distribution of the Licensed Products are duly informed of such requirements and make reasonable efforts to comply with these requirements. Hutchmed expressly agrees it will not do anything under this Agreement, directly or knowingly indirectly, which foreseeably would cause Epizyme to be in breach of Trade Control Laws. In the event that, in connection with the activities contemplated by this Agreement, Hutchmed violates any Trade Control Law or the terms or conditions set by the OFAC Authorization to any Sanctioned Countries (or in the case of a Hutchmed Entity, the Hutchmed Entity commits such violation and Hutchmed fails to terminate its agreement with the Hutchmed Entity upon becoming aware of such violation), or breaches any provision in this Section 7.5, Epizyme shall have the right to unilaterally terminate this Agreement pursuant to Section 14.4, except that the cure period set forth therein shall not apply.

(c) No License Agreement Finalized. In the event that Epizyme fails to provide the ROFN Notice during the ROFN Term or the Parties fail to execute a license agreement under the Hutchmed Dual Inhibitor Product IP for Hutchmed Dual Inhibitor Products within the ROFN Negotiation Period, then except as set forth below, the ROFN shall expire, Hutchmed shall have no further obligation to Epizyme under this Agreement with regard to Hutchmed’s interest in such Hutchmed Dual Inhibitor Product IP and Hutchmed Dual Inhibitor Products, and Hutchmed may license such Hutchmed Dual Inhibitor Product IP to any Third Party or freely exploit itself or through its Affiliates such Hutchmed Dual Inhibitor Product IP; provided, however, that if Epizyme provided the ROFN Notice during the ROFN Term but the Parties did not execute a license agreement, (i) Hutchmed shall not enter into a license agreement within [**] after the end of the ROFN Negotiation Period with any Third Party for Hutchmed Dual Inhibitor Products and Hutchmed Dual Inhibitor IP in the ROFN Epizyme Territory under license terms that Hutchmed reasonably believes are more favorable to the Third Party than the terms last offered by Epizyme to Hutchmed for the Hutchmed Dual Inhibitor Products and Hutchmed Dual Inhibitor Product IP (taking into account any differences between the scope of the proposed license agreement with such Third Party and with Epizyme, including any differences between the ROFN Epizyme Territory and the territory of such Third Party license), unless such terms are first offered to Epizyme during such [**] period and Epizyme declines such terms, and (ii) Hutchmed shall pay Epizyme (A) a royalty of [**] percent ([**]%) of net sales by Hutchmed, or any Affiliate or licensee of any Hutchmed Dual Inhibitor Product (whether as a monotherapy or combination therapy) in the Territory for a period of ten (10) years from the date of first commercial sale of the Hutchmed Dual Inhibitor Product, and (B) a royalty of [**] percent ([**]%) on net sales by Hutchmed, or any Affiliate or licensee of any Hutchmed Dual Inhibitor Product (whether as a monotherapy or combination therapy) outside of the Territory in any country in which Licensed Product is sold for a period of ten (10) years from the date of first commercial sale of the Hutchmed Dual Inhibitor Product in such country.

(d) No Rights. In no event shall any Licensed IP, Joint Combination Therapy IP, Confidential Information of Epizyme, Epizyme Product Data, Epizyme Regulatory Documents or any quantity of Licensed Compound or Licensed Product provided by Epizyme under this Agreement be used in the Development, Manufacture, or Commercialization of any Hutchmed Dual Inhibitor Product by any Hutchmed Entity inside or outside of the Territory at any time. For clarity, as of the Effective Date, Epizyme does not Control the Hutchmed Dual Inhibitor Product or any intellectual property rights therein and will not Control the Hutchmed Dual Inhibitor Product or any intellectual property rights therein unless and until Epizyme exercises its ROFN below and the Parties execute a license agreement pertaining to the Hutchmed Dual Inhibitor Product as provided in this Section 8.1. Epizyme is not obligated under this Agreement to provide, and shall not provide, any assistance to Hutchmed with respect to the Hutchmed Dual Inhibitor unless and until the Parties enter into a license agreement under this Section 8.1.

8.2 Potential Collaboration for Hutchmed Compounds and Joint Combination Therapies. Commencing as soon as practicable after the Effective Date, the Parties agree to discuss and negotiate in good faith the commercially reasonable terms and conditions of a written agreement pursuant to which Epizyme and Hutchmed shall collaborate in the Development or Commercialization in the United States of one or more Joint Combination Therapies consisting of Licensed Compound and Hutchmed Compounds; provided that, neither Party is under any obligation to enter into such a written agreement pursuant to this Section 8.2, and either Party can discontinue such negotiations at any time after the Effective Date without obligation to the other Party.

(d) Buy-In Right Payment. Notwithstanding Hutchmed’s rights pursuant to Section 2.1 or Hutchmed’s access rights pursuant to Sections 2.6(a), 2.7(a) or 5.3, for any Rejected Global Trial, after the completion of such Rejected Global Trial and upon request by Hutchmed, Epizyme shall provide to Hutchmed the data generated from such Rejected Global Trial in sufficient detail for Hutchmed to assess its interest in exercising its Buy-In Right hereunder and a summary of Epizyme’s and Epizyme Entities’ internal costs and Out-of-Pocket Costs incurred with regard to such Rejected Global Trial on a worldwide basis solely for Hutchmed’s use in determining whether to purchase rights to access, use and refer to such data in accordance with this Section 9.3(d). If after reviewing the data, Hutchmed decides in its sole discretion that it wishes to obtain the access and right of reference to all of the data or Epizyme Regulatory Documents arising out of such Rejected Global Trial, Hutchmed shall so notify Epizyme, Epizyme shall invoice Hutchmed [**] percent ([**]%) of Epizyme’s and Epizyme Entities’ internal costs and Out-of-Pocket Costs incurred with regard to such Rejected Global Trial on a worldwide basis (“Buy-In Right Payment”) and Hutchmed shall pay such Buy-In Right Payment within [**] after receipt of the invoice. Upon the receipt of the Buy-In Right Payment from Hutchmed, all such data shall be transferred to Hutchmed and shall automatically become Epizyme Product Data. For clarity, at all times, safety data from both within and outside the Territory shall be shared between the Parties under this Agreement and the Safety Data Exchange Agreement at no cost to the recipient Party in order to fulfill regulatory requirements.

(e) True-Up Payment. The Parties agree that clinical data from any Joint Global Trial will not be subject to a Buy-In Right Payment obligation under Section 9.3(d), except that, notwithstanding Hutchmed’s rights pursuant to Section 2.1 or Hutchmed’s access rights pursuant to Sections 2.6(a), 2.7(a) or 5.3, if Hutchmed or other Hutchmed Entities participate in a Joint Global Trial but do not enroll and treat in the Territory twenty percent (20%) of the total number of patients enrolled or treated globally, then upon completion of such Joint Global Trial, Hutchmed will not have the right to access or use or right of reference to the clinical data or Epizyme Regulatory Documents arising out of such Joint Global Trial unless and until Hutchmed pays Epizyme an amount equal to the product of (i) twenty percent (20%) less the quotient of (A) the total number of patients enrolled and treated in such Joint Global Trial in the Territory divided by (B) the total number of patients enrolled and treated globally in such Joint Global Trial (including such patients enrolled and treated in the Territory), multiplied by (ii) Epizyme’s and Epizyme Entities’ internal costs and Out-of-Pocket Costs incurred in the performance of such Joint Global Trial on a worldwide basis, and (iii) [**] percent ([**]%) (the “True-Up Payment”). Upon receipt of the True-Up Payment from Hutchmed, all such Regulatory Documents from such Joint Global Trial shall automatically become Epizyme Regulatory Documents, all such clinical data from such Joint Global Trial shall automatically become Epizyme Product Data, and all other Know-How arising out of such Joint Global Trial shall automatically become Epizyme Know-How. For clarity, at all times, safety data from both within and outside the Territory shall be shared by the Parties under this Agreement and the Safety Data Exchange Agreement at no cost to the recipient Party in order to fulfill regulatory requirements. Epizyme shall invoice Hutchmed for any True-Up Payment and Hutchmed shall pay such amount within [**] after receipt of the invoice.

By way of example and not limitation, if the following figures apply to a Joint Global Trial, then the True-Up Payment shall be $[**].

9.4 Licensed Product Development Milestone Payment.

(a) Hutchmed shall make the non-refundable, non-creditable, one-time milestone payments to Epizyme set forth in the table below no later than [**] (or if such payment is being made from an account in Mainland China, including where Hutchmed is receiving funds from Hutchmed China for such payment, [**]) after the earliest date on which the corresponding milestone event (“Milestone Event”) has been

54

 


 

 

achieved by any Hutchmed Entity with respect to any Licensed Product to achieve such milestone event, regardless of whether such milestone event was achieved for such Licensed Product as a monotherapy or as part of a Combination Therapy. Each of the milestone payments set forth in this Section 9.4(a) is payable only upon the first achievement of the corresponding Milestone Event by the first Licensed Product to achieve such Milestone Event and shall not be payable by any subsequent Licensed Product that achieves such Milestone Event For clarity, none of the Development milestone payments shall be payable more than once.

(b) Notwithstanding the foregoing, with respect to each of Milestone Events [**] through [**] above, the corresponding milestone payment will be made in full upon the achievement of such Milestone Event in [**] prior to its achievement in [**], and in the event any such Milestone Event is achieved in [**] prior to its achievement in [**], then [**] percent ([**]%) of the relevant milestone payment shall be made upon the achievement of the Milestone Event in [**], and the remaining [**] percent ([**]%) of the relevant milestone payment shall be made upon the achievement of the Milestone Event in [**]. For the clarity, the first achievement in [**] or [**] of any Milestone Event [**] through [**] above will not trigger any milestone payment obligations with respect to such Milestone Events. With respect to each of Milestone Events [**] through [**] above, if an applicable [**] hereunder, then the milestone payment for the applicable Milestone Event [**] through [**] shall become due upon [**]. For clarity, only one payment of either $[**] or $[**] shall become due upon the achievement of each of Milestone Events [**].

(c) Upon achievement by any Hutchmed Entity of any of the Milestone Events listed above, Hutchmed shall promptly (but in no event more than [**] (or if such payment is being made from an account in the Mainland China, including where Hutchmed is receiving funds from Hutchmed China for such payment, [**]) after such achievement) notify Epizyme of such achievement. For the avoidance of doubt,

55

 


 

 

the maximum aggregate amount payable by Hutchmed to Epizyme pursuant to this Section 9.4 is One Hundred Ten Million Dollars ($110,000,000).

9.5 Licensed Product Sales Milestone Payments. Hutchmed shall pay to Epizyme the following non-refundable and non-creditable amounts after the first achievement of aggregate Net Sales of all Licensed Products (whether as a monotherapy or as part of a Combination Therapy) in the Territory in a Calendar Year that meet or exceed the minimum annual Net Sales thresholds set forth below, which payment shall be made no later than [**] (or if such payment is being made from an account in the Mainland China, including where Hutchmed is receiving funds from Hutchmed China for such payment, [**]) after the end of the Calendar Quarter within which the applicable Calendar Year threshold(s) is(are) met or exceeded:

Each milestone payment in this Section 9.5 shall be payable only once upon the first achievement of such milestone in a given Calendar Year and no amounts shall be due for subsequent or repeated achievements of such milestone in subsequent Calendar Years. For clarity, the Net Sales of all Licensed Products in the Territory in a Calendar Year shall be aggregated for purposes of determining whether any milestone in the table above has been met. If more than one of the milestones set forth in the table above are first achieved in a single Calendar Year, then Hutchmed shall pay to Epizyme in such Calendar Year all of the payments corresponding to all of the milestones achieved in such Calendar Year under this Section 9.5.

9.6 Royalties.

(a) Licensed Product Royalty Rate. In addition to any royalties due to Third Parties under any Epizyme New In-License Agreements accepted by Hutchmed under Section 2.7(a), and subject to the remainder of this Section 9.6, Hutchmed shall pay Epizyme the following royalties on aggregate Net Sales of all Licensed Products (whether as a monotherapy or as part of a Combination Therapy) in the Territory, at an incremental royalty rate determined by aggregate Net Sales of all Licensed Products in each Calendar Year during the Royalty Term in the Territory:

Calendar Year Cumulative Net Sales in the Territory

Royalty Rate

Portion of Net Sales less than $[**]

[**]%

Portion of Net Sales equal to or greater than $[**] and less than $[**]

[**]%

Portion of Net Sales equal to or greater than $[**] and less than $[**]

[**]%

Portion of Net Sales equal to or greater than $[**]

[**]%

 

By way of example and not limitation, if aggregate Net Sales of all Licensed Products in the Territory in a Calendar Year are [**] Dollars ($[**]) and there are no Epizyme New In-License Agreements, then the royalty due to Epizyme shall be [**].

Running royalties paid by Hutchmed under this Section 9.6(a) shall be paid on a Licensed Product-by-Licensed Product and Jurisdiction-by-Jurisdiction basis commencing with the First Commercial Sale of

56

 


 

 

such Licensed Product in the such Jurisdiction and continuing until the latest of (i) the expiration of Patent-Based Exclusivity with respect to such Licensed Product in such Jurisdiction, (ii) expiration of Regulatory-Based Exclusivity with respect to such Licensed Product in such Jurisdiction, or (iii) the tenth (10th) anniversary of the First Commercial Sale of such Licensed Product in such Jurisdiction (each, a “Royalty Term”). Following the expiration of the Royalty Term with respect to a particular Licensed Product in the Field in the Territory (but not following an earlier termination of this Agreement), the licenses granted by Epizyme to Hutchmed pursuant to Section 2.1 with respect to such Licensed Product in the Field in the Territory shall be perpetual, irrevocable, fully-paid and royalty-free, and freely sublicensable through multiple tiers and not subject to Section 2.4 and Net Sales of such Licensed Product shall no longer be included in the aggregate Net Sales calculation in Section 9.5 or 9.6(a). For clarity, the Royalty Term is determined on a Jurisdiction-by-Jurisdiction basis but the applicable royalty rate in the table above for each Jurisdiction is determined based on cumulative Calendar Year Net Sales in the Territory.

(b) Royalty Reductions.

(i) No Patent-Based or Regulatory-Based Exclusivity. The foregoing provisions of this Section 9.6 notwithstanding, the royalties payable with respect to Net Sales of Licensed Products shall be reduced, on a Licensed Product-by-Licensed Product basis, to [**] percent ([**]%) of the amounts otherwise payable pursuant to Section 9.6(a) during any portion of the Royalty Term when either Patent-Based Exclusivity or Regulatory-Based Exclusivity does not apply to such Licensed Product in the Territory.

(ii) Royalty Reduction for Comparable Third Party Product Competition. If on a Licensed Product-by-Licensed Product and Calendar Quarter-by-Calendar Quarter basis, during the applicable Royalty Term (or portion thereof), (A) Comparable Third Party Product Competition is present with respect to such Licensed Product in the Territory during such Calendar Quarter, or (B) a court or a Governmental Authority of competent jurisdiction requires Epizyme or any Hutchmed Entity to grant a compulsory license to a Third Party permitting such Third Party to make and sell such Licensed Product in the Territory (such Licensed Product when sold by such Third Party, a “Compulsory Third Party Product”), and such Compulsory Third Party Product(s) have a market share of [**] percent ([**]%) or more of the aggregate market in the Territory of the applicable Licensed Product and the Compulsory Third Party Product(s) collectively (based on sales of units of such Licensed Product and such Compulsory Third Party Product(s), as reported by IQVIA, or if such data are not available, such other reliable data source as reasonably determined by Epizyme and Hutchmed (as used herein, a “unit” of a product means the equivalent amount of product used for an equivalent treatment cycle of such product)), then, in each case of clause (A) or (B), the royalty rate under Section 9.6(a) applicable to the Net Sales of such Licensed Product in the Territory and Calendar Quarter shall be reduced by [**] percent ([**]%) of the royalty rate otherwise payable pursuant to Section 9.6(a).

(iii) Third Party Payments.

(A) Hutchmed In-License Agreements. Hutchmed shall be entitled to credit against the royalties due to Epizyme on Net Sales of a Licensed Product in the Territory an amount equal to [**] percent ([**]%) of all upfront payments, milestone payments, royalties, and other amounts paid by Hutchmed or other Hutchmed Entities to Third Parties with respect to license rights to Third Party intellectual property licensed by Hutchmed or the other Hutchmed Entity from the applicable Third Party that are necessary or reasonably useful for the Development, Manufacture, or Commercialization of such Licensed Product in such country; provided, however, that, to the extent that any such Third Party license includes a license to Third Party intellectual property that is applicable to products being

57

 


 

 

or to be developed or commercialized by Hutchmed or other Hutchmed Entities other than such Licensed Product in the Territory, then Hutchmed shall reasonably allocate all upfront payments, milestone payments and other non-royalty amounts between the Licensed Product and such other products, and Hutchmed shall only be entitled to credit against the royalties due Epizyme hereunder on Net Sales of such Licensed Product [**] percent ([**]%) of the amounts that are reasonably allocable to the Licensed Product.

(B) Epizyme New In-License Agreements. In the event Epizyme enters into any Third Party IP license necessary for the Development, Manufacture, or Commercialization of a Licensed Product in the Territory, under which Epizyme is entitled to grant a sublicense to Hutchmed, and Hutchmed accepts such sublicense from Epizyme under Section 2.7(a), then, subject to any reductions or allocations pursuant to Section 2.7(a), Hutchmed shall pay [**] percent ([**]%) of the amounts payable to the Third Party on account of such sublicense arising out of Hutchmed’s exercise of rights under such sublicenses and otherwise allocated to Hutchmed pursuant to Section 2.7(a) (either directly to the Third Party licensor or to Epizyme, as the Parties shall reasonably agree with the goal of ensuring timely payment to the Third Party) and Hutchmed shall be entitled to credit against the royalties due to Epizyme on Net Sales of such Licensed Product in the Territory in an amount equal to [**] percent ([**]%) of the amounts paid by Hutchmed (either directly or indirectly through Epizyme) to such Third Party with respect to such license rights for such Licensed Product in the Territory.

(iv) Aggregate Limitation on Deductions. Notwithstanding anything to the contrary herein, under no circumstances shall the combined effect of all reductions to the royalties payable to Epizyme under this Section 9.6, on a Licensed Product-by-Licensed Product basis in the Territory, reduce the effective royalties payable by Hutchmed pursuant to this Agreement for any Calendar Quarter below [**] percent ([**]%) of the otherwise applicable royalties pursuant to Section 9.6(a); provided that, Hutchmed shall have the right to carry forward for application against royalties payable to Epizyme with respect to Net Sales of Licensed Product in the Territory in future periods any amount that is not so credited due to the limitation in this Section 9.6(b)(iv).

(c) Blended Royalty. Hutchmed acknowledges that (i) the licensed Know-How and the Know-How included in the Epizyme Regulatory Documents are proprietary and valuable and that without such Know-How and Epizyme Regulatory Documents Hutchmed would not be able to obtain and maintain Regulatory Approvals with respect to the Licensed Products in the Territory, (ii) such Regulatory Approvals may allow Hutchmed to obtain and maintain Regulatory-Based Exclusivity with respect to the Licensed Products, (iii) access to Epizyme’s Know-How and the rights with respect to the Epizyme Regulatory Documents have provided Hutchmed with a competitive advantage in the marketplace, and (iv) the milestone payments and royalties set forth in this Article 9 are, in part, intended to compensate Epizyme for such exclusivity and such competitive advantage. The Parties agree that the royalty rates set forth in Section 9.6 reflect and efficient and reasonable blended allocation of the value provided to Hutchmed by Epizyme.

(d) Royalty Reports. On a Licensed Product-by-Licensed Product basis, until the expiration of the Royalty Term with respect to such Licensed Product in the Territory, Hutchmed agrees to (i) send an email to Epizyme within [**] after the end of each Calendar Quarter with a good faith, non-binding estimate of the amount of the royalties owed with respect to such Licensed Product in the Territory in such Calendar Quarter and (ii) provide quarterly written reports to Epizyme within [**] after the end of each Calendar Quarter, covering all Net Sales of such Licensed Product in the Territory by any Hutchmed Entity, each such written report stating for the period in question the number of units sold of each Licensed Product in Mainland China, Taiwan, Hong Kong, and Macau during the applicable Calendar Quarter (including such amounts expressed in local currency and as converted to Dollars), the gross sales for each Licensed Product,

58

 


 

 

as applicable, a calculation of the adjustments to Net Sales for Combination Products (if applicable) and the calculation of the royalty payment due on such Net Sales for such Calendar Quarter pursuant to this Article 9. Such report shall also include a calculation of the amount of royalty payment due on Net Sales for such Calendar Quarter that are payable pursuant to any Epizyme New In-License Agreement, or if such calculation cannot be made by Hutchmed, such report shall include the information reasonably needed from Hutchmed in order for Epizyme to make such calculation, as communicated in writing by Epizyme to Hutchmed. The information contained in each report under this Section 9.6(d) shall be considered the Confidential Information of Hutchmed.

(e) Royalty Payments. Hutchmed shall make the royalty payments due hereunder (including royalties owed under any Epizyme New In-License Agreement) within [**] after the end of each Calendar Quarter.

9.7 ROFN Term Payments. In the event Epizyme determines, pursuant to Section 8.1, to pay to prevent the ROFN from lapsing during any month after the ROFN POC Date and the commencement of the ROFN Term, Epizyme shall make a non-refundable, non-creditable payment to Hutchmed in the amount of [**] Dollars ($[**]) for each such month (each, a “ROFN Term Payment”), which amount will be pro-rated for any partial month period. Hutchmed shall invoice Epizyme for such amount on a Calendar Quarter basis and Epizyme shall pay each such invoice within [**] after receipt thereof.

9.8 Recordkeeping.

(a) Each Hutchmed Entity shall keep full, clear and accurate records of Licensed Products that are made, used or sold under this Agreement and of any costs borne by such Hutchmed Entity for any Joint Global Trial, in accordance with the Accounting Standards, for a period of at least [**] after the end of the Calendar Year to which the records relate, setting forth the sales of Licensed Products in sufficient detail to enable royalties and other amounts payable to Epizyme and Hutchmed’s payment obligations under Sections 5.2, 9.3(c), 9.3(d), and 9.3(e) and Article 7 hereunder to be determined. Each Hutchmed Entity further agrees to permit its books and records to be examined by an independent accounting firm selected by Epizyme and reasonably acceptable to Hutchmed no more than [**], to verify any reports and payments delivered under this Agreement during the [**], upon reasonable notice (which shall be no less than [**] prior notice) and during regular business hours and subject to a reasonable confidentiality agreement. The Parties shall reconcile any underpayment or overpayment within [**] after the accounting firm delivers the results of any audit. Such examination is to be made at the expense of Epizyme, except in the event that the results of the audit reveal an underpayment by Hutchmed of [**] percent ([**]%) or more during the period being audited, in which case reasonable audit fees for such examination shall be paid by Hutchmed.

(b) Each Epizyme Entity shall keep full, clear and accurate records of internal costs and Out-of-Pocket Costs for the performance of each Joint Global Trial and costs incurred in accordance with Sections 5.2 and Article 7 (including Epizyme’s Fully-Burdened Cost and Manufacturing Activity Costs), in accordance with the Accounting Standards, for a period of at least [**] after the end of the Calendar Year to which the records relate, in sufficient detail to enable Hutchmed’s payment obligations under Sections 5.2, 9.3(c), 9.3(d), and 9.3(e) and Article 7 to be determined. Each Epizyme Entity further agrees to permit its books and records to be examined by an independent accounting firm selected by Hutchmed and reasonably acceptable to Epizyme no more than [**], to verify any invoices delivered under Sections 5.2, 9.3, and Article 7 during the [**], upon reasonable notice (which shall be no less than [**] prior notice) and during regular business hours and subject to a reasonable confidentiality agreement. The Parties shall reconcile any underpayment or overpayment within [**] after the accounting firm delivers the results of any audit. Such examination is to be made at the expense of Hutchmed, except in the event that the results of the audit reveal an overcharging by Epizyme of [**] percent ([**]%) or more during the period being audited, in which case reasonable audit fees for such examination shall be paid by Epizyme.

59

 


 

 

(c) To the extent required by any agreement between Epizyme and RPI Finance Trust pertaining to RPI Finance Trust’s purchase of royalties on future sales of Tazemetostat, Hutchmed agrees that Epizyme shall provide any such required financial information to RPI Finance Trust, subject to written obligations of nondisclosure and non-use no less stringent than those set forth in Article 10.

9.9 Currency Conversion. Wherever it is necessary to convert currencies for Net Sales invoiced in a currency other than the Dollar, such conversion shall be made into Dollars at the conversion rate used by Hutchmed for its own financial reporting purposes in connection with its other products or accounts, consistently applied, in accordance with Accounting Standards. All payments due to Epizyme under this Agreement shall be made without deduction of exchange, collection or other charges. Once the amount of Net Sales paid to Epizyme in respect of a particular Calendar Quarter has been converted into Dollars, such amount of Dollars shall be used for the purpose of calculating the total amount of Net Sales during the Calendar Year that includes such Calendar Quarter.

9.10 Methods of Payment. All payments due to a Party under this Agreement shall be made by the other Party (and not any Affiliate of the other Party) in Dollars by wire transfer to a bank account of and designated by such Party (and not any Affiliate of such Party). In case any payment to be made by Hutchmed to Epizyme under this Agreement requires filing or approval of a Regulatory Authority under Applicable Law, including filings with relevant foreign exchange administrations in Mainland China, Hong Kong, or British Virgin Islands, Hutchmed shall take prompt actions to apply for and complete such filings or approvals in advance of the payment so that the payment can be made on a timely basis pursuant to the terms and conditions of this Agreement.

9.11 Taxes. Each Party shall be responsible for its own past, current, and future Taxes on such Party’s income in accordance with the applicable tax regulations of any relevant tax jurisdiction. Each Party making a payment under this Agreement (a “Payor”) shall inform the other Party (a “Payee”) of any withholding tax obligation imposed by taxing authorities on payments due to the Payee under this Agreement as soon as it becomes aware of the withholding tax obligation. The Parties shall meet promptly thereafter to discuss how best to minimize the amount of such withholding tax obligation. The Payor shall in good faith take all reasonable and lawful steps requested by the Payee to minimize the amount of any such withholding tax obligation at the Payor’s expense, and the Payee shall in good faith take all reasonable and lawful steps requested by the Payor to minimize the amount of any such withholding tax obligation at the Payee’s expense. The Parties agree to cooperate in good faith to provide one another with such documents and certifications as are reasonably necessary to enable Hutchmed and Epizyme to minimize or recover any withholding tax payment. Hutchmed may withhold Taxes in the event that revenue authorities in any country require the withholding of taxes on amounts paid hereunder to Epizyme in accordance with applicable tax regulations, and Epizyme may withhold taxes in the event that revenue authorities in any jurisdiction require the withholding of taxes on amounts paid hereunder to Hutchmed in accordance with applicable tax regulation. In any such event the Payor shall deduct such taxes from such payment and such taxes shall be paid by the Payor to the proper taxing authority on behalf of the Payee (evidence of which payment to such taxing authority shall be provided promptly by the Payor to the Payee hereunder). Hutchmed shall be responsible for all customs’ duties, import tariffs, freight, insurance, inspection costs and the like attributed to or for the transport and importation of any Licensed Product in or into the Territory under this Agreement.

9.12 Late Payments. Interest shall be payable by Payor on any amounts payable to Payee under this Agreement which are not paid by the due date for payment. All interest shall accrue and be calculated on a daily basis (both before and after any judgment) at a rate per month equal to the lesser of (a) [**]

60

 


 

 

percentage points above the then-current “prime rate” in effect published in The Wall Street Journal or (b) the maximum rate permissible under Applicable Law, for the period from the due date for payment until the date of actual payment. The payment of such interest shall not limit Payee from exercising any other rights it may have as a consequence of the lateness of any payment.

9.13 Invoices. Epizyme acknowledges that Hutchmed requires invoices for all payments due under this Agreement, which invoices may be delivered by email to [**] (which email address may be changed by Hutchmed from time to time upon written notice to Epizyme). Hutchmed acknowledges that Epizyme requires invoices for all payments due under this Agreement, which invoices may be delivered by email to [**] (which email address may be changed by Epizyme from time to time upon written notice to Hutchmed).

10.3 Permitted Disclosures. Notwithstanding any other provision of this Agreement, Recipient’s disclosure of the Discloser’s Confidential Information shall not be prohibited if such disclosure: (a) is required by any Applicable Law, including as may be required in connection with any filings made with, or by the disclosure policies of the U.S. Securities and Exchange Commission (“SEC”) (or similar foreign authority) or other Governmental Authority, or of a nationally or internally recognized securities exchange such as NASDAQ (as set forth in additional detail below) provided that Recipient seeking to disclose the Confidential Information of the other Party uses all reasonable efforts to inform the other Party prior to making any such disclosures and cooperate with the other Party in seeking a protective order or other appropriate remedy (including redaction) and whenever possible, requests confidential treatment of such information; (b) to prosecute or defend litigation so long as there is [**] prior written notice given by the Recipient before filing, and to enforce Patent Rights in connection with Recipient’s rights and obligations pursuant to this Agreement, or (c) is to patent offices in order to seek or obtain Patent Rights as contemplated by this Agreement or to Governmental Authorities including Regulatory Authorities in order to seek or obtain approval to Develop, Manufacture, and Commercialize the Licensed Product as contemplated by this Agreement, including to conduct clinical trials or to gain Regulatory Approval with respect to the Licensed Products; provided that such disclosure may be made only to the extent reasonably necessary to seek or obtain such Patent Rights or approvals, and the Recipient (or its applicable Affiliate(s)) shall use Commercially Reasonable Efforts to obtain confidential treatment of such information.

Notwithstanding anything to the contrary set forth in this Agreement, if a Recipient is required to make a disclosure of the Discloser’s Confidential Information pursuant to Section 10.3(a) or (b) above, then it will, to the extent not prohibited by Applicable Law or judicial or administrative process, except where impracticable, give reasonable advance notice to the other Party of such proposed disclosure and use reasonable efforts to secure confidential treatment of such information and will only disclose that portion of Confidential Information that is legally required to be disclosed as advised by its legal counsel. In addition, the Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement (or portions thereof or an abstract of the terms) with the SEC or other Governmental Authorities. Each Party will be entitled to make such a required filing; provided that it initially files a redacted copy of this Agreement (or portions thereof or an abstract of the terms) approved by each Party and requests confidential treatment of the terms redacted for a reasonable period of time. In the event of any such filing, each Party will permit the other Party to review and comment upon such request for confidential treatment and any subsequent correspondence with respect thereto at least [**] in advance of its submission to the SEC or other Governmental Authorities, and to the extent practicable before any filing deadline, (A) reasonably consider and incorporate the other Party’s comments thereon to the extent consistent with the then-current legal requirements governing redaction of information from material agreements that must publicly filed in the applicable country, (B) promptly provide to the other Party any correspondence from or other communications with such Governmental Authority, (C) upon written request of the other Party, request an appropriate extension of the term of the confidential treatment period, where available, and (D) if such Governmental Authority requests any changes to the redactions set forth in the filed redacted copy, use reasonable efforts to support the redactions in the redacted agreement as originally filed and, to the extent reasonably practicable, not agree to any changes to the redactions without first discussing such changes with the other Party and taking the other Party’s comments into consideration when deciding whether to agree to such changes.

10.4 Publicity. The press release attached to this Agreement as Exhibit E shall be issued by both Parties on the Effective Date. Thereafter, the Parties recognize that each Party may from time to time desire to issue press releases and make other public statements or public disclosures (each, a “Public Statement”) in respect of this Agreement, including the Development or Commercialization of Licensed Products in the Territory. If Hutchmed desires to make a Public Statement, it shall provide Epizyme a copy of such Public Statement at least [**] prior to the date it desires to make such public disclosure. Hutchmed shall not issue a Public Statement without Epizyme’s prior written approval, which advance approval shall not be

62

 


 

 

unreasonably withheld, conditioned or delayed. Epizyme shall provide to Hutchmed a preliminary draft of any Public Statement that it intends to make on a global basis with respect to Development of Licensed Products at least [**] in advance of such public disclosure and shall provide a final draft of such Public Statement at least [**] in advance of such public disclosure; provided that, if such Public Statement includes data owned by Hutchmed with respect to a Local Trial or Pre-Clinical Research conducted by Hutchmed in the Territory, Epizyme shall obtain Hutchmed’s prior written approval to include such data, which approval shall not be unreasonably withheld, conditioned or delayed. Once any public statement or public disclosure has been approved in accordance with this Section 10.4, then the applicable Party may communicate information contained in such permitted statement or disclosure. Notwithstanding anything to the contrary in this Section 10.4, nothing in this Section 10.4 shall be deemed to limit either Party’s rights under Section 10.3.

10.5 Publications. Epizyme acknowledges Hutchmed’s interest in publishing certain key results of Hutchmed’s Development and Commercialization of Licensed Products in the Field in the Territory. Hutchmed recognizes the mutual interest in obtaining valid patent protection and Epizyme’s interest in protecting its proprietary information.

(a) By Hutchmed. Except for disclosures permitted pursuant to Sections 10.2, 10.3 or 10.4, if Hutchmed wishes to make a publication or public presentation with respect to its Development or Commercialization of Licensed Products in the Field in the Territory, Hutchmed shall deliver to Epizyme a copy of the proposed written publication or presentation; for manuscripts, at least [**] prior to submission, or for abstracts or posters, at least [**] prior to submission. Epizyme shall respond in writing in no event later than [**] after receipt of a proposed manuscript or [**] after receipt of a proposed abstract or poster. Epizyme shall have the right (i) to require modifications to the publication or presentation for patent or any other business reasons, and Hutchmed will remove all of Epizyme’s Confidential Information if requested by Epizyme, and (ii) to require a reasonable delay in publication or presentation in order to protect patentable information. If Epizyme requests a delay, then Hutchmed shall delay submission or presentation for a period of [**] (or such period as may be mutually agreed by the Parties) to enable Epizyme to file patent applications protecting Epizyme’s rights in such patentable information.

(b) By Epizyme. Except for disclosures permitted pursuant to Sections 10.2, 10.3 or 10.4, if Epizyme wishes to make a publication or public presentation with respect to its Development or Commercialization of Joint Combination Therapies or the results of any Joint Global Trial, Epizyme shall deliver to Hutchmed a copy of the proposed written publication or presentation; for manuscripts, at least [**] prior to submission, or for abstracts or posters, at least [**] prior to submission. Hutchmed shall respond in writing in no event later than [**] after receipt of a proposed manuscript or [**] after receipt of a proposed abstract or poster. Hutchmed shall have the right (i) to require modifications to the publication or presentation for patent or any other business reasons, and Epizyme will remove all of Hutchmed’s Confidential Information if requested by Hutchmed, and (ii) to require a reasonable delay in publication or presentation in order to protect patentable information. If Hutchmed requests a delay, then Epizyme shall delay submission or presentation for a period of [**] (or such period as may be mutually agreed by the Parties) to enable Hutchmed or Epizyme to file patent applications protecting the Parties’ rights in such patentable information. In addition, unless prohibited by confidentiality obligations to any Third Party, Epizyme shall provide Hutchmed with a draft of any other publication pertaining to Licensed Products reasonably in advance of submission for publication.

10.6 Injunctive Relief. Each Party acknowledges and agrees that there may be no adequate remedy at law for any breach of its obligations under this Article 10, that any such breach may result in irreparable harm to the other Party and, therefore, that upon any such breach or any threat thereof, such other Party may seek appropriate equitable relief in addition to whatever remedies it might have at law, without the necessity of showing actual damages.

63

 


 

 

10.7 Information Security. During the Term, each Party will maintain safety and facility procedures, data security procedures and other safeguards against the disclosure, destruction, loss, or alteration of the other Party’s information in its possession.

In the event that (A) Applicable Law prohibits the assignment to Epizyme

64

 


 

 

of inventions, discoveries, or Patent Rights included in Epizyme Combination Therapy IP, Epizyme IP, or Epizyme Manufacturing IP, then in lieu of the assignment of such inventions, discoveries, or Patent Rights to Epizyme, Hutchmed will grant and hereby grants to Epizyme, without cost to Epizyme, as broad, exclusive and unrestricted license to, with the broadest enforcement rights with respect to, such inventions, discoveries, or Patent Rights as allowable under Applicable Law, or (B) despite the good faith efforts of Hutchmed to obtain an assignment obligation from a Hutchmed Entity (other than Hutchmed), the Hutchmed Entity (other than Hutchmed) does not agree to an assignment to Epizyme of inventions, discoveries, or Patent Rights included in Epizyme Combination Therapy IP, Epizyme IP, or Epizyme Manufacturing IP (other than intellectual property rights constituting improvements to such Hutchmed Entity’s background intellectual property), then in lieu of the assignment of such inventions, discoveries, or Patent Rights to Epizyme, Hutchmed will obtain from the Hutchmed Entity the rights necessary to grant to Epizyme and Hutchmed will grant and hereby grants to Epizyme, without cost to Epizyme, as broad, exclusive and unrestricted a license to, with the broadest enforcement rights with respect to, such inventions, discoveries, or Patent Rights (other than intellectual property rights constituting improvements to such Hutchmed Entity’s background intellectual property) as agreed with such Hutchmed Entity. In each case ((A) and (B)), such inventions and discoveries (other than intellectual property rights constituting improvements to such Hutchmed Entity’s background intellectual property) shall be deemed Epizyme Combination Therapy Know-How, Epizyme Know-How, or Epizyme Manufacturing Know-How, as applicable, and such Patent Rights shall be deemed Epizyme Combination Therapy Patent Rights, Epizyme Patent Rights or Epizyme Manufacturing Patent Rights, as applicable, hereunder, and Hutchmed shall provide to Epizyme any necessary or reasonably requested documentation reflecting such licenses and shall assist Epizyme in all other reasonable ways that are necessary for Epizyme to enjoy and exploit or enforce any such Know-How and Patent Rights. For clarity, all such Epizyme Combination Therapy IP, Epizyme IP, and Epizyme Manufacturing IP assigned to Epizyme by Hutchmed shall be included in the applicable licenses granted by Epizyme to Hutchmed under Section 2.1.

Hutchmed will take, and cause the Hutchmed Entities to take, with Epizyme bearing Hutchmed’s reasonable Out-of-Pocket Costs with respect to, all action reasonably requested by Epizyme to evidence such assignment and to assist Epizyme in obtaining Patent Rights and other intellectual property protection for Know-How within the Epizyme Combination Therapy IP, Epizyme IP, or Epizyme Manufacturing IP, including rendering all signature that shall be necessary for the relevant patent filings and assisting Epizyme in all other reasonable ways that are necessary for the Prosecution of any such Patent Rights by Epizyme as set forth in Section 11.2.

(c) Joint Combination Therapy IP. The Parties shall jointly own any Joint Combination Therapy IP except that, as between the Parties, Epizyme shall own any Joint Combination Therapy IP that is Controlled by Epizyme as of the Effective Date or is Controlled by Epizyme during the Term under any Epizyme In-License Agreement, and Hutchmed shall own any Joint Combination Therapy IP that is Controlled by Hutchmed as of the Effective Date or is Controlled by Hutchmed during the Term under any Hutchmed In-License Agreement. Each Party shall promptly disclose in writing to the other Party any inventions (whether or not patentable) or discoveries conceived, identified, discovered, authored, developed, or reduced to practice during the Term solely or jointly by or behalf of Epizyme or Hutchmed Entity and included in Joint Combination Therapy Know-How upon becoming aware thereof, but in any event no later than [**] after the conception, identification, discovery, authorship, development or reduction to practice thereof. Each Party will assign and does hereby assign to the other Party, subject to the licenses granted in Sections 2.1 and 2.2, a one-half undivided interest in all of such Party’s rights, title and interests in and to any and all inventions, discoveries or Patent Rights included in Joint Combination Therapy IP. Each Party shall, without cost to the other Party, obtain all necessary assignment documents for the other Party to give effect to the one-half undivided ownership described above, render all signatures that shall be necessary for the relevant patent filings and assist the other Party in all other reasonable ways that are necessary for the Prosecution of the Joint Combination Therapy Patent Rights by the other Party as set forth in Section

65

 


 

 

11.2(c). Subject to the terms and conditions of this Agreement, including Sections 2.5 and 2.8 and the licenses granted herein, each Party is entitled to practice any Joint Combination Therapy IP for all purposes on a worldwide basis and to license such Joint Combination Therapy IP through multiple tiers without consent of the other Party (where consent is required by Applicable Law, such consent is deemed hereby granted) and without a duty of accounting to the other Party.

(d) Joint IP. Subject to the terms and conditions of this Agreement, including Sections 2.5 and 2.8 and the licenses granted herein, each Party is entitled to practice any Joint IP for all purposes on a worldwide basis and to license such Joint IP through multiple tiers without consent of the other Party (where consent is required by Applicable Law, such consent is deemed hereby granted) and without a duty of accounting to the other Party.

(e) Each Party shall be solely responsible for payments due under Applicable Laws regarding inventor remuneration to each inventor as to any Patent Right described in the foregoing Section 11.1(a)-(d) to which such Party is assigned an ownership interest by such inventor.

11.2 Prosecution of Patent Rights.

(a) Licensed Patent Rights. Subject to the terms of each Epizyme In-License Agreement:

(i) As between the Parties, Epizyme shall have the sole right, but not the obligation, to Prosecute all Epizyme Combination Therapy Patent Rights, Epizyme Patent Rights, and Epizyme Manufacturing Patent Rights (individually and collectively, the “Licensed Patent Rights”) and their foreign counterparts worldwide. Hutchmed shall reimburse Epizyme, on a Calendar Quarter basis, for all Out-of-Pocket Costs incurred by Epizyme or any of its Affiliates after the Effective Date in the Territory in Prosecuting the Licensed Patent Rights (for the avoidance of doubt, including amounts paid by Epizyme after the Effective Date to any Third Party counterparty under any Epizyme In-License Agreement with respect to such Third Party counterparty’s Prosecution of applicable Licensed Patent Rights in the Territory), within [**] after receiving an invoice therefor.

Hutchmed shall furnish Epizyme with copies of each document relevant to such Prosecution at least [**] prior (or such shorter period prior if it is not reasonably practicable to provide such copies [**] prior) to filing such document or making any payment due thereunder to allow for review and comment by such other Party and shall consider in good faith timely comments from such other Party thereon. Hutchmed shall also furnish Epizyme with copies of all final filings and responses made to any patent authority with respect to the Hutchmed Patent Rights being Prosecuted by Hutchmed in a timely manner following submission thereof.

(c) Joint Combination Therapy Patent Rights. Subject to the terms of each Epizyme In-License Agreement and Hutchmed In-License Agreement:

(i) Epizyme shall have the first right, but not the obligation, to Prosecute all Joint Combination Therapy Patent Rights outside the Territory, and Hutchmed shall have the first right, but not the obligation, to Prosecute all Joint Combination Therapy Patent Rights in the Territory The Parties shall [**] of all Out-of-Pocket Costs incurred by the Prosecuting Party after the Effective Date in Prosecuting such Joint Combination Therapy Patent Rights in and outside the Territory. The non-Prosecuting Party shall reimburse its share of such costs on a [**] basis within [**] after receiving an invoice from the Prosecuting Party therefor. If the Prosecuting Party elects not to, or is unable to, Prosecute any Joint Combination Therapy Patent Rights in any country anywhere in the world, or intends to allow a Joint Combination Therapy Patent Right to lapse or become abandoned without having first filed a substitute, the Prosecuting Party shall give the non-Prosecuting Party prompt notice and shall permit the non-Prosecuting Party at the non-Prosecuting Party’s own expense to take such actions itself in such country.

(ii) The Party Prosecuting a Joint Combination Therapy Patent Right in accordance with Section 11.2(c)(i) shall consult with the other Party on the Prosecution of all Joint Combination Therapy Patent Rights, and shall take into consideration the commercial and patent strategies for Joint Combination Therapies of (A) if the Party Prosecuting is Epizyme, in the Territory, and (B) if the Party Prosecuting is Hutchmed, globally. The Party Prosecuting shall furnish the other Party with copies of each document relevant to such Prosecution at least [**] prior (or such shorter period prior if it is not reasonably practicable to provide such copies [**] prior) to filing such document or making any payment due thereunder to allow for review and comment by the other Party and shall consider in good faith timely comments from the other Party thereon. The Party Prosecuting shall also furnish the other Party with copies of all final filings and responses made to any patent authority with respect to the Joint Combination Therapy Patent Rights in a timely manner following submission thereof. The other Party shall execute such documents and perform such acts as may be reasonably necessary for the Prosecuting Party to perform such actions.

(iii) In preparing, filing, prosecuting and maintaining Joint Combination Therapy Patent Rights, in no event shall Hutchmed take any position that is contrary to or detrimental to the scope or enforceability of any Epizyme Patent Rights or any Patent Rights owned or otherwise controlled by Epizyme that are counterparts to any Epizyme Patent Rights without the express written consent of Epizyme.

(d) Patent Liaisons. Promptly (but in no event later than [**]) following the Effective Date, the Parties shall each designate a representative to consult with the other Party’s representative with respect to the Prosecution of the Licensed Patent Rights, Hutchmed Patent Rights, and Joint Combination Therapy Patent Rights (such representatives, the “Patent Liaisons”). The Patent Liaisons shall discuss and provide input to each other, at such times, places and frequencies as mutually agreed, on all material issues with

67

 


 

 

respect to the Prosecution of such Patent Rights; provided that all final decisions related to the Prosecution, enforcement or defense of the Licensed Patent Rights, Hutchmed Patent Rights, and Joint Combination Therapy Patent Rights shall be made by the Party with the right to control such Prosecution, enforcement or defense, as applicable as set forth in this Article 11.

11.3 Enforcement and Defense. Subject to the terms of each Epizyme In-License Agreement:

(a) If either Party becomes aware of any Third Party activity, including any Development activity (whether or not an exemption from infringement liability for such Development activity is available under Applicable Law), that materially infringes (or that is directed to the Development of a product that would infringe) a Licensed Patent Right, Hutchmed Patent Right or a Joint Combination Therapy Patent Right, or that misappropriates any Epizyme Combination Therapy Know-How, Epizyme Know-How, or Epizyme Manufacturing Know-How (individually or collectively the “Licensed Know-How”), Hutchmed Know-How, or Joint Combination Therapy Know-How, or of any Third Party Patent Right that, if issued or enforced, is reasonably likely to materially affect the scope, claims, validity, or other material element of a Licensed Patent Right, Hutchmed Patent Right or a Joint Combination Therapy Patent Right then the Party becoming aware of such activity shall give prompt written notice to the other Party regarding such alleged infringement or misappropriation (collectively, “Infringement Activity”).

(b) Epizyme shall have the first right, but not the obligation, to attempt to resolve any Infringement Activity involving Licensed Patent Rights, Licensed Know-How, Joint Combination Therapy Patent Rights, or Joint Combination Therapy Know-How outside the Territory at its own expense, including the filing of an infringement or misappropriation suit using counsel of its own choice, and Hutchmed shall have the first right, but not the obligation, to attempt to resolve any Infringement Activity involving Licensed Patent Rights, Licensed Know-How, Epizyme Marks, Joint Combination Therapy Patent Rights, or Joint Combination Therapy Know-How in the Territory by commercially appropriate steps at its own expense, including the filing of an infringement or misappropriation suit using counsel of its own choice. If (i) Hutchmed fails to resolve such Infringement Activity in the Territory, or (ii) solely with respect to Joint Combination Therapy Patent Rights, Epizyme fails to resolve such Infringement Activity outside the Territory, but solely (in the case of this clause (ii)) where the allegedly infringing product is or would be competitive with Hutchmed’s Other Combination Drug(s) that form(s) part of a Joint Combination Therapy covered by such Joint Combination Therapy Patent Rights, or, in either case ((i) or (ii)), to initiate a suit with respect thereto by the date that is [**] before any deadline for taking action to avoid any loss of material enforcement rights or remedies, then, upon written notice to the non-enforcing Party, such Party shall have the right, but not the obligation, to attempt to resolve such Infringement Activity by commercially appropriate steps at its own expense, including the filing of an infringement or misappropriation suit using counsel of its own choice.

(c) Any amounts recovered by a Party as a result of an action pursuant to Section 11.3(b), whether by settlement or judgment, shall be allocated as follows: (i) first to pay to each Third Party counterparty under any Epizyme In-License Agreement or Hutchmed In-License Agreement any amounts owed to such Third Party counterparty with respect to such enforcement action, then (ii) to reimburse the Parties for their costs and expenses of the enforcement action (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses), and (iii) any remaining amount shall be shared between the Parties, with the enforcing Party retaining [**] percent ([**]%) of such amount and the other Party retaining [**] percent ([**]%) of such amount. In the event that any action pursuant to this Section 11.3 does not result in the recovery of any amounts (e.g., payments to a Third Party, expenses for invalidation proceedings for Third Party Patent Rights that a Party reasonably believes may infringe a Licensed Patent Right, Hutchmed Patent Right or a Joint Combination Therapy Patent Right), then unless otherwise provided by this Agreement, such expenses shall be borne equally by the Parties and the Party not incurring such expenses

68

 


 

 

shall reimburse the incurring Party within [**] after receipt of an invoice reasonably documenting such expenses.

(d) If a Third Party in the context of an enforcement action under this Section 11.3 asserts that a Licensed Patent Right or Joint Combination Therapy Patent Right is invalid or unenforceable, then the Party responsible for such enforcement action will be responsible for defending against such assertion. If a Third Party outside of an enforcement action under this Section 11.3 asserts that a Licensed Patent Right is invalid or unenforceable, then Epizyme shall have the sole right, but not the obligation, to defend against such assertion. If a Third Party outside of an enforcement action under this Section 11.3 asserts that a Joint Combination Therapy Patent Right is invalid or unenforceable, then Epizyme shall have the sole right, but not the obligation, outside the Territory, and Hutchmed shall have the first right, but not the obligation, within the Territory, to defend against such assertion (such Party with a sole or first right to defend being known as the “First Defending Party”) and, at the First Defending Party’s request and expense, the other Party shall provide reasonable assistance in defending against such Third Party assertion. The First Defending Party shall (i) keep the other Party reasonably informed regarding such assertion and such defense (including by providing such other Party with drafts of each filing a reasonable period before the deadline for such filing and promptly providing such other Party with copies of all final filings and correspondence), (ii) consult with the other Party on such defense, and (iii) consider in good faith all comments from the other Party regarding such defense. The non-defending Party shall have the right to join as a party to such defense and participate with its own counsel at its sole expense; provided, however, that the First Defending Party shall retain control of such defense. Should Epizyme (with respect to Licensed Patent Rights or Joint Combination Therapy Patent Rights outside the Territory, including in the context of an applicable enforcement action) or Hutchmed (with respect to Joint Combination Therapy Patent Rights within the Territory or in the context of an applicable enforcement action) decide that it is not, or is no longer, interested in controlling such defense with respect to a Joint Combination Therapy Patent Right, it shall promptly (and in any event by the date that is [**] before any deadline for taking action to avoid any loss of material rights) provide the other Party written notice of this decision. The other Party may, upon written notice to such first Party, assume such defense at such other Party’s sole expense.

(e) In any event, at the request and expense of the Party bringing an infringement or misappropriation action under Section 11.3(b) or defending an action under Section 11.3(d), the other Party shall provide reasonable assistance in any such action (including entering into a common interest agreement if reasonably deemed necessary by any Party) and be joined as a party to the suit if necessary for the initiating or defending Party to bring or continue such suit. Neither Party may settle any action or proceeding brought under Section 11.3(b) or 11.3(d), or knowingly take any other action in the course thereof, in a manner that materially adversely affects the other Party’s interest in any Licensed Patent Rights or Joint Combination Therapy Patent Rights or counterpart Patent Rights outside of the Territory without the written consent of such other Party. Each Party shall always have the right to be represented by counsel of its own selection and its own expense in any suit or other action instituted by the other Party pursuant to Section 11.3(b) or 11.3(d). The Party enforcing a Licensed Patent Right or Joint Combination Therapy Patent Right will keep the other Party reasonably informed with respect to the status of such enforcement and will consider in good faith all comments provided by the non-enforcing Party with respect to such enforcement.

11.4 Defense of Third Party Infringement and Misappropriation Claims. Subject to the terms of each Epizyme In-License Agreement:

(a) If a Third Party asserts that a Patent Right or other right controlled by it in the Territory is infringed or misappropriated by a Party’s activities under this Agreement or a Party becomes aware of a Patent Right or other right that might form the basis for such a claim, the Party first obtaining knowledge of such a claim or such potential claim shall immediately provide the other Party with notice thereof and

69

 


 

 

the related facts in reasonable detail. Subject to Section 13.1, the Parties shall discuss what commercially appropriate steps, if any, to take to avoid infringement or misappropriation of said Third Party Patent Right or other right controlled by such Third Party in the Territory.

(b) If a Third Party asserts that a Patent Right or other right controlled by it in the Territory is infringed or misappropriated by a Party’s activities under this Agreement, then, subject to Section 13.1, such Party shall have the first right, but not the obligation, to defend against such assertion and, at such Party’s request and expense, the other Party will provide reasonable assistance in defending against such Third Party assertion. Such Party shall keep the other Party reasonably informed regarding such assertion and such defense.

11.5 Patent Linkage. To the extent required by Applicable Law, Hutchmed shall use Commercially Reasonable Efforts to promptly, accurately and completely list, with the applicable Regulatory Authorities in the Territory, all applicable Patents for any Licensed Product that Hutchmed intends to, or has begun to, Commercialize and that have become the subject of an application for Regulatory Approval submitted to Regulatory Authorities in the Territory. Prior to such listings, the Parties shall meet to evaluate and identify all applicable Patents, and Hutchmed shall retain final decision-making authority as to the listing of all applicable Patents for such Licensed Product in the Territory, regardless of which Party owns such Patent.

11.6 Patent Term Extensions. Subject to the terms of each Epizyme In-License Agreement, the Parties shall discuss and select the appropriate Licensed Patent Rights or Joint Combination Therapy Patent Rights for filing to obtain patent term extensions, including supplementary protection certificates and any other extensions that are now available or become available in the future, based on Regulatory Approvals for Licensed Products in the Field in the Territory. If the Parties are unable to reach mutual agreement, as between the Parties, Hutchmed shall have the right to make the final decision as to such Patent Rights. In such cases, Epizyme shall consult with Hutchmed with respect to such decisions and shall consider the comments and concerns of the other Party in good faith. Hutchmed shall cooperate with Epizyme in gaining any such patent term extensions, including by signing all necessary papers.

Such supply shall be at Hutchmed’s Fully-Burdened Cost.

(d) Upon termination by Epizyme under Section 14.3, 14.4. or 14.6, to the extent permitted under Applicable Law, Hutchmed shall, as requested by Epizyme on a clinical trial-by-clinical trial basis: (i) promptly wind down any clinical trial then being conducted with respect to any Licensed Product in the Territory or (ii) transfer any clinical trial then being conducted with respect to any Licensed Product in the Territory to any Epizyme Entity or a Third Party as specified by Epizyme, at Hutchmed’s expense; provided

that Hutchmed shall be permitted to take all reasonable steps necessary to minimize liability and harm to patients in this process. Upon termination by Hutchmed under Section 14.3, 14.4. or 14.6, Hutchmed shall promptly wind down any clinical trial then being conducted with respect to any Licensed Product in the Territory; provided that Hutchmed shall be permitted to take all reasonable steps necessary to minimize liability and harm to patients in this process.

(e) Hutchmed shall cease using the Licensed IP and, subject to a sell-off period not to exceed six (6) months after the effective date of termination, return all inventory of the Licensed Compound and Licensed Product (including Drug Substance and Drug Product) to Epizyme after such [**] period, together with all copies of the Licensed Know-How and other Confidential Information of Epizyme in the possession or control of Hutchmed or any of its Representatives, and if termination is by Hutchmed under Section 14.3, 14.4 or 14.6, Epizyme shall refund Hutchmed the applicable Clinical Supply Price or Commercial Supply Price for such Licensed Compound and Licensed Product returned to Epizyme;

(f) Hutchmed shall, at Epizyme’s written request, to the extent reasonably feasible under Applicable Law, promptly: (i) assign and transfer to Epizyme all of the Hutchmed Entities’ right, title, and interest in and to all Hutchmed Regulatory Documents (including Regulatory Filings and Regulatory Approvals), clinical trial agreements (to the extent assignable), confidentiality and other agreements, and materials and Know-How solely relating to any Licensed Product, and solely to the extent in any Hutchmed Entity’s possession or control, and (ii) disclose to Epizyme all documents embodying the foregoing that are in any Hutchmed Entity’s possession or control or that any Hutchmed Entity is able to obtain using reasonable efforts;

(g) at Epizyme’s request, Hutchmed shall promptly take all action that may be reasonably required to transfer to Epizyme or a Third Party designated by Epizyme all portions of customer lists, promotional materials and any other information it has generated for selling the Commercialization of the Licensed Products in the Territory that are (i) solely related to the Licensed Products and (ii) not subject to any confidentiality obligations to any Third Parties or other restrictions on sharing such information with Epizyme;

(h) Except as otherwise provided in this Agreement, including in connection with clinical trials pursuant to Sections 14.7(c) and 14.7(d) and Hutchmed’s sell-down right in Section 14.7(e), Hutchmed shall also cease immediately the use of any Internet website solely relating to any Licensed Product as well as any Epizyme Mark;

(i) The Manufacturing Technology Transfer Agreement shall terminate as of the effective date of termination of this Agreement;

(j) The Hutchmed Entities’ Out-of-Pocket Costs associated with the activities set forth in this Section 14.7 shall be borne by (i) Hutchmed, if this Agreement is terminated by Epizyme pursuant to Section 14.3, Section 14.4, Section 14.6 or Section 17.1, or by Hutchmed pursuant to Section 14.2, or (ii) Epizyme, if this Agreement is terminated by Hutchmed pursuant to Section 14.3, 14.4, 14.6, or 17.1;

(k) If Epizyme does not obtain the right to sublicense Third Party IP to Hutchmed in the Territory pursuant to Section 2.7(a) (and as a result is not permitted to enter into any agreement with respect to such Third Party IP that includes any grant of rights in the Field in the Territory) and Hutchmed obtains rights (with the right to sublicense) to such Third Party IP in the Field in the Territory, then at Epizyme’s written election, the Parties shall negotiate in good faith the commercially reasonable terms under which Hutchmed would grant Epizyme a non-exclusive license under such Third Party IP; and

81

 


 

 

(l) Notwithstanding any expiration or termination of this Agreement, the Safety Data Exchange Agreement (with respect to Hutchmed’s obligations thereunder) shall continue in accordance with its terms.

The following articles and sections of this Agreement shall survive expiration or early termination for any reason: Article 1, Section 2.3, Section 2.5, Section 2.6(b), Section 2.7 (solely to the extent applicable to a Party’s exercise of any rights, or performance of any obligations, retained by such Party hereunder following the applicable expiration or termination), Section 4.10, Section 4.13, Section 5.3, Section 5.5, Section 5.6, Section 5.7, Section 6.6 (second sentence only), Section 7.5 (solely with respect to any Licensed Product sold following expiration or early termination of this Agreement in accordance with Section 14.7(e)), Article 9 (solely with respect to any payment obligations incurred prior to expiration or termination), Article 10, Section 11.1, Section 11.2 (with respect to Joint Combination Therapy Patent Rights), Section 11.3 (with respect to Joint Combination Therapy Patent Rights), Section 12.7, Section 12.8, Section 12.9, Article 13, Section 14.6, Section 14.7, this Section 14.8, Article 15, Section 16.1, Section 16.2, and Article 17. In any event, expiration or termination of this Agreement shall not relieve either Party of any liability which accrued hereunder prior to the effective date of such expiration or termination nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement, nor prejudice either Party’s right to obtain performance of any obligation.

Article 15. DISPUTE RESOLUTION; GOVERNING LAW

15.1 Arbitration. Other than any dispute that relates to the validity or enforceability of a Patent Right, which shall be resolved in accordance with Section 15.1(c) or a dispute that relates to Net Sales, which shall be resolved in accordance with Section 1.139, any dispute, claim or controversy in connection with this Agreement, including any question regarding its formation, existence, validity, enforceability, performance, interpretation, breach or termination, that is not resolved in accordance with Article 3 and is not subject to a Party’s final decision-making authority in accordance with Article 3 (each, a “Dispute”) shall be referred to and finally resolved by binding arbitration under the International Chamber of Commerce (“ICC”) Rules of Arbitration (the “Rules”), which Rules are deemed to be incorporated by reference into this Section 15.1, in the manner described below:

(a) Arbitration Request. If a Party intends to begin an arbitration to resolve a Dispute arising under this Agreement, such Party shall provide written notice (the “Arbitration Request”) to the other Party of such intention and the issues for resolution. Within [**] after the receipt of an Arbitration Request, the other Party may, by written notice, add additional issues for resolution. Any such Dispute shall be resolved in accordance with Section 15.1(b).

(b) General Arbitration Procedure for Disputes. The seat of arbitration will be in London, England unless another venue is agreed upon by Parties, and it will be conducted in the English language. The arbitrators may not decide based on equity. Unless agreed by the Parties to choose a single common arbitrator, the arbitration will be conducted by three arbitrators, one appointed by each Party, according to the Rules. The two arbitrators appointed by the Parties will by mutual agreement appoint the third arbitrator, who will preside over the arbitration. Any dispute or omission regarding the appointment of the arbitrators by the Parties, as well as the choice of the third arbitrator, will be resolved by the ICC. The arbitral award shall be final, definitive and binding on the Parties and their successors. The Parties reserve the right to apply to a competent judicial court to obtain urgent remedies to protect rights before establishment of the arbitration panel, without such recourse being considered as a waiver of arbitration. Except as otherwise determined by the arbitrators, the Parties shall each bear half of the fees and expenses of the arbitrators and the ICC, and each Party shall bear the costs and fees of its attorneys. Nothing in this Agreement shall be deemed as preventing either Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute

82

 


 

 

as necessary to protect either Party’s name, Confidential Information, Know-How, intellectual property rights or any other proprietary right or otherwise to avoid irreparable harm. If the issues in dispute involve scientific or technical matters, any arbitrators chosen hereunder shall have educational training or experience sufficient to demonstrate a reasonable level of knowledge in the field of biotechnology and pharmaceuticals. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. The Parties intend that each award rendered by an arbitrator hereunder shall be entitled to recognition and enforcement under the United Nations Convention on the Recognition and Enforcement of Arbitral Awards (New York, 1958).

(c) Intellectual Property Disputes. Unless otherwise agreed by the Parties, a dispute between the Parties relating to the validity or enforceability of any Patent Right shall not be subject to arbitration and shall be submitted to a court or patent office of competent jurisdiction in the relevant country or jurisdiction in which such patent was issued or, if not issued, in which the underlying patent application was filed. For the avoidance of doubt, in addition to any remedies available to Epizyme hereunder, Epizyme shall have the right to seek injunctive relief from any court of competent jurisdiction in the Territory against Hutchmed for any infringement by Hutchmed of Licensed Patent Rights.

15.2 Choice of Law. This Agreement and all amendments, modifications, alterations, or supplements hereto, and the rights of the Parties hereunder, shall be construed under and governed by the laws of the State of New York, exclusive of its conflicts of laws principles.

15.3 Language. This Agreement has been prepared in the English language and the English language shall control its interpretation. Except as explicitly provided otherwise in this Agreement, all consents, notices, and reports, to be delivered or provided by a Party under this Agreement shall be in the English language, and in the event of any conflict between the provisions of any such consent, notice, or report and the English language translation thereof, the terms of the English language translation shall control.

Article 16. ASSIGNMENT AND CHANGE OF CONTROL

16.1 Assignment.

(a) Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by either Party (and, for these purposes, a merger, sale of assets, operation of law or other transaction shall be deemed an assignment) without the prior written consent of the other Party. Notwithstanding the foregoing, either Party may, without the other Party’s written consent, assign this Agreement and its rights and obligations hereunder in whole or in part to (i) an Affiliate of such Party for so long as such Affiliate remains an Affiliate of such Party or (ii) a Third Party that acquires, by or otherwise in connection with, a merger, sale of assets or otherwise, all or substantially all of the business of such Party to which the subject matter of this Agreement relates; provided that the assignee agrees in writing to assume all of such Party’s obligations under this Agreement. The assigning Party will remain responsible for the performance by its assignee of this Agreement or any obligations hereunder so assigned.

(b) The terms of this Agreement will be binding upon and will inure to the benefit of the successors, heirs, administrators and permitted assigns of the Parties. Any purported assignment in violation of this Section 16.1 will be null and void ab initio.

16.2 Consequences of a Party becoming an Acquired Party.

(a) Each Party agrees that, in the event that a Party or any of its Affiliates (the “Acquired Party”) is acquired through a Change in Control by one or more persons or entities (collectively, the “Acquirer”), the Acquired Party shall be deemed not to “Control” for purposes of this Agreement, and the non-Acquired

83

 


 

 

Party shall not obtain any rights or access under this Agreement to, any Know-How or Patent Rights owned by or licensed to such Acquirer, or any of such Acquirer’s Affiliates that were not Affiliates of the Acquired Party immediately prior to the consummation of such Change in Control, that were not already within Licensed IP (if the Acquired Party is Epizyme or any of its Affiliates) or Hutchmed IP (if the Acquired Party is Hutchmed or any of its Affiliates) or Joint Combination Therapy IP immediately prior to the consummation of such Change in Control or that such Acquirer develops following the consummation of such Change in Control without access to or use of the Acquired Party’s information or intellectual property. Each Party shall notify the other Party promptly after any Change in Control of such Party or any of its Affiliates. The Acquired Party will notify the other Party of the Change of Control within [**] after closing of the Change of Control.

(b) If, during the Term, either Party or any of its Affiliates becomes an Acquired Party, then, such Change of Control shall not alter or diminish Hutchmed’s diligence obligations hereunder. If, during the Term, a Party or any of its Affiliates becomes an Acquired Party and the Acquirer or an Affiliate of the Acquirer has a Competing Product, then unless otherwise agreed by the other Party, the Acquired Party or such Affiliate will notify the other Party in writing within [**] after the closing date of the Change of Control that the Acquirer or such Affiliate will, at its election:

(i) divest, whether by license, divestiture of assets or otherwise, its interest in such Competing Product, as applicable, in the Territory to a Third Party, to the extent necessary to be in compliance with Section 2.8, as applicable, provided that the Acquirer or its applicable Affiliate may retain an economic interest through such a license, divestiture of assets or other transaction as long as the Acquirer or its applicable Affiliate does not retain any other material rights as to such Competing Product, as applicable, in the Territory beyond a passive economic interest; or

(ii) terminate the Development, Manufacture and Commercialization of such Competing Product, as applicable, in the Territory, to the extent necessary to be in compliance with Section 2.8, as applicable; or

(iii) implement reasonable measures to keep the Acquirer’s and its applicable Affiliates’ activities relating to any Competing Product(s) of the Acquirer or its Affiliates in the Territory separated from the Acquirer’s and its applicable Affiliates’ activities relating to the Licensed Products in the Territory, and subject to the Acquirer and its applicable Affiliates implementing such measures, the Acquirer’s and its applicable Affiliates’ Development, Manufacture and Commercialization of such Competing Product(s) shall be deemed not to violate Section 2.8.

If the Acquired Party or any of its Affiliates notifies the other Party in writing that it or its relevant Affiliate intends to divest such Competing Product, as applicable, or terminate the Development, Manufacture and Commercialization of the Competing Product, as applicable, in the Territory as provided in clause (i) or clause (ii) of this Section 16.2(b), then the Acquired Party or its relevant Affiliate will effect such divestiture or termination within [**] after the date of the relevant acquisition or other event, subject to compliance with Applicable Law, and will confirm to the other Party in writing when such divestiture or termination has been completed. The Acquired Party will keep the other Party reasonably informed of its and its Affiliates’ efforts and progress in effecting such divestiture or termination until it is completed. Until such divestiture or termination occurs, the Acquired Party shall (1) keep its and its Affiliates’ activities with respect to such Competing Product, as applicable, separate from their activities with respect to the Licensed Products, and (2) continue to fully perform all of their obligations hereunder with respect to Licensed Products, including their applicable diligence obligations with respect to the Development and Commercialization of Licensed Products hereunder.

84

 


 

 

16.3 Consequences of a Party Acquiring a Third Party.

(a) Without altering or diminishing Hutchmed’s diligence obligations hereunder, if, during the Term, either Party or any of its Affiliates acquires a Third Party (whether by way of a purchase of assets, merger, consolidation, Change in Control or otherwise) that is, at such time, Developing, Manufacturing or Commercializing a Competing Product in a manner that, if performed by the acquiring Party or any of its Affiliates, would violate Section 2.8, then the acquiring Party or its applicable Affiliate will notify the non-acquiring Party of the closing of the relevant acquisition within [**]. Unless otherwise agreed by the non-acquiring Party, the acquiring Party or such Affiliate will notify the non-acquiring Party in writing within [**] of the closing date that the acquiring Party or such Affiliate will:

(i) divest, whether by license, divestiture of assets or otherwise, its interest in such Competing Product, as applicable, in the Territory to a Third Party, to the extent necessary to be in compliance with Section 2.8, as applicable, provided that the acquiring Party or its applicable Affiliate may retain an economic interest through such a license, divestiture of assets or other transaction as long as the acquiring Party does not retain any other material rights as to such Competing Product, as applicable, in the Territory beyond a passive economic interest;

(ii) with respect to Hutchmed as the acquiring Party, terminate this Agreement in accordance with Section 14.2; or

(iii) terminate the Development, Manufacture and Commercialization of such Competing Product, as applicable, in the Territory, to the extent necessary to be in compliance with Section 2.8, as applicable.

If the acquiring Party or any of its Affiliates notifies the non-acquiring Party in writing that it or its relevant Affiliate intends to divest such Competing Product, as applicable, or terminate the Development, Manufacture and Commercialization of the Competing Product, as applicable, in the Territory as provided in this Section 16.3, then the acquiring Party or its relevant Affiliate will effect such divestiture or termination within [**] after the date of the relevant acquisition or other event, subject to compliance with Applicable Law, and will confirm to the non-acquiring Party in writing when such divestiture or termination has been completed. The acquiring Party will keep the non-acquiring Party reasonably informed of its and its Affiliates’ efforts and progress in effecting such divestiture or termination until it is completed. Until such divestiture or termination occurs, the acquiring Party shall keep its and its Affiliates’ activities with respect to such Competing Product, as applicable, separate from their activities with respect to the Licensed Products and shall continue to fully perform all of their obligations hereunder with respect to Licensed Products, including their applicable diligence obligations with respect to the Development and Commercialization of Licensed Products hereunder.

Article 17. MISCELLANEOUS

17.1 Force Majeure. If either Party shall be delayed, interrupted in or prevented from the performance of any obligation hereunder by reason of a force majeure event, which may include any act of God, fire, flood, earthquake, public disaster, war (declared or undeclared), act of terrorism, epidemic or pandemic, government action, strike or labor differences, or lack of or inability to obtain raw materials, fuel, or power, in each case outside of such Party’s reasonable control, and whether or not such force majeure event is foreseeable as of the Effective Date, such Party shall not be liable to the other therefor, and the time for performance of such obligation shall be extended for a period equal to the duration of the force majeure event which occasioned the delay, interruption or prevention. The Party invoking the force majeure rights of this Section 17.1 must notify the other Party by courier or overnight dispatch (e.g., Federal Express) within a period of [**] of both the first and last day of the force majeure event unless the force majeure

85

 


 

 

renders such notification impossible, in which case notification will be made as soon as possible. During the pendency of any force majeure event, the Party subject to such force majeure shall use Commercially Reasonable Efforts to terminate such force majeure or to mitigate the effects of such force majeure so that such Party can still perform its obligations under this Agreement. If the delay resulting from the force majeure event exceeds [**], the other Party may terminate this Agreement immediately upon written notice to the Party.

17.2 Entire Agreement. This Agreement, together with the exhibits and schedules attached hereto, constitutes the entire agreement between Epizyme or any of its Affiliates, on the one hand, and Hutchmed or any of its Affiliates, on the other hand, with respect to the subject matter hereof, supersedes all prior understandings and writings between Epizyme or any of its Affiliates, on the one hand, and Hutchmed or any of its Affiliates, on the other hand relating to such subject matter, including the Confidentiality Agreement, and, subject to Section 4.3, shall not be modified, amended or (subject to Article 14) terminated, except by another agreement in writing executed by the Parties.

17.3 Severability. If, under Applicable Law, any provision of this Agreement is invalid or unenforceable, or otherwise directly or indirectly affects the validity of any other material provision of this Agreement (such invalid or unenforceable provision, a “Severed Clause”), it is mutually agreed that this Agreement shall endure except for the Severed Clause. The Parties shall consult one another and use their reasonable efforts to agree upon a valid and enforceable provision that is a reasonable substitute for the Severed Clause in view of the intent of this Agreement.

17.4 Notices. Any notice required or permitted to be given under this Agreement shall be in writing and shall be mailed by internationally recognized express delivery service, or sent by facsimile or email and confirmed by mailing, as follows (or to such other address as the Party to whom notice is to be given may have furnished to the other Party in writing in accordance herewith):
