RISK FACTORS

Investing in our securities involves a high degree of risk. In determining whether to purchase our common stock, an investor should carefully consider all of the material risks described below, together with the other information contained in this report before making a decision to purchase our securities. An investor should only purchase our securities if he or she can afford to suffer the loss of his or her entire investment.

Risks Related to Our Business

We have expressed substantial doubt about our ability to continue as a going concern.

As discussed in Note 1 to the consolidated financial statements for the year ended June 30, 2018, our audited financial statements for the fiscal year ended June 30, 2018, include an explanatory paragraph that such financial statements were prepared assuming that we will continue as a going concern. A going concern basis assumes that we will continue our operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business.

For the year ended June 30, 2018 and the nine months ended March 31, 2019, we reported a loss of $11,138,312 and $5,465,486, respectively, and a negative cash flow from operations of $9,850,850 and $4,514,674, respectively. We had an accumulated deficit of $57,988,567 as at March 31, 2019. As at March 31, 2019, we had cash and cash equivalents on hand of $2,152,233. We are in the development stage and have not generated any revenues to date. We do not have the prospect of achieving revenues until such time that our product candidate is commercialized, or partnered, which may not ever occur. In the near future, we will require additional funding to maintain our clinical studies, research and development projects, and for general operations. These circumstances indicate substantial doubt exists about our ability to continue as a going concern.

Consequently, management is pursuing various financing alternatives to fund our operations, including this Rights Offering, so it can continue as a going concern. Management plans to secure the necessary financing through the issue of new equity and/or the entering into of strategic partnership arrangements. We may tailor our drug candidate development program based on the amount of funding we are able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.

The financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. Such adjustments could be material.

We have a limited operating history and a history of operating losses and expect to incur significant additional operating losses.

We are an early stage company and there is limited historical financial information upon which to base an evaluation of our performance. Our prospects must be considered in light of the uncertainties, risks, expenses, and difficulties frequently encountered by companies in their early stages of operations. We expect to incur substantial additional net expenses over the next several years as our research, development and commercial activities increase. The amount of future losses and when, if ever, we will achieve profitability are uncertain. Our ability to generate revenue and achieve profitability will depend on, among other things, successful completion of the preclinical and clinical development of our product candidate; obtaining necessary regulatory approvals from the FDA and international regulatory agencies; successful manufacturing, sales and marketing arrangements; and raising sufficient funds to finance our activities. If we are unsuccessful at some or all of these undertakings, our business, prospects and results of operations may be materially adversely affected.

We will need to raise additional capital, which may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings and/or license and development agreements with collaboration partners. As of March 31, 2019, we had cash and cash equivalents to fund operations into the middle of calendar 2019. We expect the net proceeds from this Right Offering to be $1.2 million assuming all of the securities are sold, which, together with the expected net proceeds from the RD Offering of approximately

$3.2 million, we expect to fund our operations until into the first quarter of calendar 2020. We will also need to raise additional capital to fund our operations. We do not have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, then -existing stockholders’ interests may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect their rights as common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends. In addition, debt financing would result in fixed payment obligations.

In addition, we have retained Oppenheimer & Co. Inc. as a financial advisor to assist us in our evaluation of a broad range of strategic alternatives to enhance stockholder value, including additional capital raising transactions, an acquisition, merger, business combination, licensing and/or other strategic transaction involving us. There is no assurance that the review of strategic alternatives will result in us changing our business plan, pursuing any particular transaction, or, if we pursue any such transaction, that it will be completed. We do not expect to make further public comment regarding the strategic review until our Board of Directors has approved a specific transaction or otherwise deems disclosure of significant developments is appropriate.

If we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds 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.

Our inability to obtain additional financing could adversely affect our ability to meet our obligations under our planned clinical studies and could negatively impact the timing of our clinical results.

Our ability to meet our obligations and continue the research and development of our product candidate is dependent on our ability to continue to raise adequate financing. We may not be successful in obtaining such additional financing in the amount required at any time, or for any period, or, if available, that it can be obtained on terms satisfactory to us. In the event that we are unable to obtain such additional financing, we may be unable to meet our obligations under our planned clinical studies and we may have to tailor our drug candidate development programs based on the amount of funding we raise which could negatively impact the timing of our clinical results. In addition, we could be required to cease our operations.

Our exploration and pursuit of strategic alternatives may not be successful.

In September 2018, we announced that we had retained Oppenheimer & Co. Inc. as a financial advisor to assist us in our evaluation of a broad range of strategic alternatives. Potential strategic alternatives that may be explored or evaluated as part of this process include the potential for capital raising transactions, an acquisition, merger, business combination, licensing and/or other strategic transaction involving us. Despite devoting efforts to identify and evaluate potential strategic transactions, the process may not result in any definitive offer to consummate a strategic transaction, or, if we receive such a definitive offer, the terms may not be as favorable as anticipated or may not result in the execution or approval of a definitive agreement. Even if we enter into a definitive agreement, we may not be successful in completing a transaction or, if we complete such a transaction, it may not enhance stockholder value or deliver expected benefits.

If we fail to regain compliance with the stockholders’ equity requirements of the Nasdaq Capital Market LLC (“Nasdaq”) or other requirements for continued listing, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.

Our common stock is listed for trading on Nasdaq. On May 22, 2019 and May 23, 2019, the Company received written notices (collectively, the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that, in light of the Company having reported stockholders’ equity of $1,259,161 as of March 31, 2019 in its Quarterly Report on Form 10 -Q for the quarter ended March 31, 2019, the Company was not in compliance with the $2,500,000 minimum stockholders’ equity requirement set forth in Nasdaq Listing Rule 5550(b)(1) for continued listing on The Nasdaq Capital Market (the “Stockholders’ Equity Requirement”), or with

any alternative standard under the Nasdaq Listing Rules. The Notice requested that the Company present a plan to regain compliance with the above -mentioned deficiency by written submission no later than May 29, 2019, which plan was submitted on such date, in order to be considered by the Nasdaq Hearings Panel that was, until May 23, 2019, considering the Company’s continued listing due to the Company’s previous deficiency with respect to the $1.00 per share bid price requirement, as described below. The Company expects to utilize the proceeds from this Rights Offering and the RD Offering towards establishing compliance with such requirement; provided that the Company will need to raise additional capital to obtain compliance.

As previously disclosed, on June 28, 2018, the Staff of the Listing Qualifications Department of Nasdaq (the “Nasdaq Staff”) notified the Company that it did not comply with the minimum $1.00 per share bid price requirement for continued listing, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”), and the Company was therefore granted 180 calendar days, through December 26, 2018, to regain compliance. On December 27, 2018, the Nasdaq Staff notified the Company that it had not regained compliance with the Bid Price Requirement, that the Company’s stockholders’ equity as reported in the Company’s Quarterly Report on Form 10 -Q for the quarter ended September 30, 2018 did not qualify the Company for an additional 180 calendar day extension period for compliance and that it would therefore be subject to delisting unless it requested a hearing before a Nasdaq Hearings Panel. Accordingly, the Company requested a hearing, which was held on January 31, 2019, at which it presented its plan of compliance. On February 4, 2019, the Nasdaq Hearings Panel issued a decision granting the Company’s request for continued listing of its common stock on The Nasdaq Capital Market pursuant to an extension through June 25, 2019, subject to the condition that the Company shall have demonstrated a closing bid price of $1.00 per share or more for a minimum of ten consecutive business days by June 25, 2019. As a result of the Company’s previously disclosed one -for-ten reverse stock split effected on May 8, 2019, on May 23, 2019, the Company received written notice from Nasdaq that the Company has regained compliance with the Bid Price Requirement.

Pending the Nasdaq Hearings Panel’s decision on the Stockholders’ Equity Requirement deficiency, the Company’s common stock will continue to be listed on Nasdaq, and the Company’s common stock will continue to trade under the symbol “DMPI.” The Company’s receipt of the Notice does not affect the Company’s business, operations or reporting requirements with the SEC.

Notwithstanding, there can be no assurance of the results of the Nasdaq Hearings Panel’s consideration or that we will be able to regain compliance, and if we are unable to regain compliance with the stockholders’ equity requirement, or if we fail to meet any of the other continued listing requirements, our securities may be delisted from Nasdaq, which could reduce the liquidity of our common stock materially and result in a corresponding material reduction in the price of our common stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, employees and business development opportunities. Such a delisting likely would impair your ability to sell or purchase our common stock when you wish to do so. Further, if we were to be delisted from Nasdaq, our common stock may no longer be recognized as a “covered security” and we would be subject to regulation in each state in which we offer our securities. Thus, delisting from Nasdaq could adversely affect our ability to raise additional financing through the public or private sale of equity securities, would significantly impact the ability of investors to trade our securities and would negatively impact the value and liquidity of our common stock.

If we are unable to effectively implement or maintain a system of internal control over financial reporting, we may not be able to accurately or timely report our financial results and our stock price could be adversely affected.

Section 404 of the Sarbanes -Oxley Act of 2002 and related regulations require us to evaluate the effectiveness of our internal control over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal control over financial reporting in our Annual Report on Form 10 -K for that fiscal year. Management determined that as of June 30, 2018 and in past periods, our disclosure controls and procedures and internal control over financial reporting were not effective due to material weaknesses in our internal control over financial reporting related to our limited number of employees in our accounting department and inadequate segregation of duties over authorization, review and recording of transactions, as well as the financial reporting of such transactions. Any failure to implement new or improved controls necessary to remedy the material weaknesses described above, or difficulties encountered in the implementation or operation of these controls, could

harm our operations, decrease the reliability of our financial reporting, and cause us to fail to meet our financial reporting obligations, which could adversely affect our business and reduce our stock price.

We are an early-stage company and may never achieve commercialization of our candidate products or profitability.

We are at an early stage of development and commercialization of our technologies and product candidate. We have not yet begun to market any products and, accordingly, have not begun or generate revenues from the commercialization of our product. Our product will require significant additional clinical testing and investment prior to commercialization. A commitment of substantial resources by ourselves and, potentially, our partners to conduct time -consuming research and clinical studies will be required if we are to complete the development of our product candidate. There can be no assurance that our product candidate will meet applicable regulatory standards, obtain required regulatory approvals, be capable of being produced in commercial quantities at reasonable costs or be successfully marketed. Our product candidate is not expected to be commercially available for several years, if at all.

We are currently focused on the development of a single product candidate.

Our product development efforts are currently focused on a single product, VAL -083 , for which we are researching multiple indications. If VAL -083 fails to achieve clinical endpoints or exhibits unanticipated toxicity or if a superior product is developed by a competitor, our prospects for obtaining regulatory approval and commercialization may be negatively impacted. In the long -term , we hope to establish a pipeline of product candidates, and we have identified additional product candidates that we may be able to acquire or license in the future. However, at this time we do not have any formal agreements granting us any rights to such additional product candidates.

Even if we are able to commercialize any product candidate that we develop, the product may become subject to unfavorable pricing regulations, third-party payor reimbursement practices or healthcare reform initiatives that could harm our business.

The commercial success of our current or future product candidates will depend substantially, both domestically and abroad, on the extent to which the costs of our product candidate will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities (such as Medicare and Medicaid), private health coverage insurers and other third -party payors. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize our products. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish and maintain pricing sufficient to realize a meaningful return on our investment.

There is significant uncertainty related to third -party payor coverage and reimbursement of newly approved drugs. Marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some non -U .S. markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch of the product, possibly for lengthy time periods, which may negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize VAL -083 or any other product candidates will depend in part on the extent to which coverage and reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third -party payors, such as private health insurers and health maintenance organizations, decide which medications they will cover and establish reimbursement levels. The healthcare industry is acutely focused on cost containment, both in the United States and elsewhere. Government authorities and third -party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications, which could affect our ability to sell our product candidate profitably. These payors may not view our products, if any, as cost -effective , and coverage and reimbursement may not be available to our customers, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost -control initiatives could cause us to decrease the price we might establish

for products, which could result in lower than anticipated product revenues. If the prices for our products, if any, decrease or if governmental and other third -party payors do not provide adequate coverage or reimbursement, our prospects for revenue and profitability will suffer.

There may also be delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the indications for which the drug is approved by the FDA or comparable non -U .S. regulatory authorities. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Reimbursement rates may vary, by way of example, according to the use of the drug and the clinical setting in which it is used. Reimbursement rates may also be based on reimbursement levels already set for lower cost drugs or may be incorporated into existing payments for other services.

In addition, increasingly, third -party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and are challenging the prices charged. We cannot be sure that coverage will be available for any product candidate that we, or they, commercialize and, if available, that the reimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. An inability to promptly obtain coverage and adequate payment rates from both government -funded and private payors for any of our product candidates for which we obtain marketing approval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

We are dependent on obtaining certain patents and protecting our proprietary rights.

Our success will depend, in part, on our ability to obtain patents, maintain trade secret protection and operate without infringing on the proprietary rights of third parties or having third parties circumvent our rights. We have filed and are actively pursuing patent applications for our products. The patent positions of biotechnology, biopharmaceutical and pharmaceutical companies can be highly uncertain and involve complex legal and factual questions. Thus, there can be no assurance that any of our patent applications will result in the issuance of patents, that we will develop additional proprietary products that are patentable, that any patents issued to us or those that already have been issued will provide us with any competitive advantages or will not be challenged by any third parties, that the patents of others will not impede our ability to do business or that third parties will not be able to circumvent our patents. Furthermore, there can be no assurance that others will not independently develop similar products, duplicate any of our products not under patent protection, or, if patents are issued to us, design around the patented products we developed or will develop.

We may be required to obtain licenses from third parties to avoid infringing patents or other proprietary rights. No assurance can be given that any licenses required under any such patents or proprietary rights would be made available, if at all, on terms we find acceptable. If we do not obtain such licenses, we could encounter delays in the introduction of products or could find that the development, manufacture or sale of products requiring such licenses could be prohibited.

A number of pharmaceutical, biopharmaceutical and biotechnology companies and research and academic institutions have developed technologies, filed patent applications or received patents on various technologies that may be related to or affect our business. Some of these technologies, applications or patents may conflict with our technologies or patent applications. Such conflict could limit the scope of the patents, if any, that we may be able to obtain or result in the denial of our patent applications. In addition, if patents that cover our activities are issued to other companies, there can be no assurance that we would be able to obtain licenses to these patents at a reasonable cost or be able to develop or obtain alternative technology. If we do not obtain such licenses, we could encounter delays in the introduction of products, or could find that the development, manufacture or sale of products requiring such licenses could be prohibited. In addition, we could incur substantial costs in defending ourselves in suits brought against us on patents it might infringe or in filing suits against others to have such patents declared invalid.

Patent applications in the U.S. are maintained in secrecy and not published if either: i) the application is a provisional application or ii) the application is filed and we request no publication, and certify that the invention disclosed “has not and will not” be the subject of a published foreign application. Otherwise, U.S. applications or foreign counterparts, if any, publish 18 months after the priority application has been filed. Since publication of discoveries in the scientific or patent literature often lag behind actual discoveries, we cannot be certain that we or any licensor were the first creator of inventions covered by pending patent applications or that we or such licensor was the first to file patent applications for such inventions. Moreover, we might have to participate in interference proceedings declared

by the U.S. Patent and Trademark Office to determine priority of invention, which could result in substantial cost to us, even if the eventual outcome were favorable to us. There can be no assurance that our patents, if issued, would be held valid or enforceable by a court or that a competitor’s technology or product would be found to infringe such patents.

Moreover, we may be subject to third -party preissuance submissions of prior art to the USPTO, or become involved in opposition, derivation, reexamination, inter partes review, post -grant review or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third -party patent rights.

Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us, or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non -infringing manner.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be challenged in courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate, or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

In addition, the protection of intellectual property rights in China (where our clinical product candidate, VAL -083 , is manufactured pursuant to a collaboration agreement with the only manufacturer presently licensed by the CFDA to manufacture VAL -083 for the China market, and where VAL -083 is approved for the treatment of CML and lung cancer) is relatively weak compared to the United States, which may negatively affect our ability to generate royalty revenue from sales of VAL -083 in China.

Much of our know -how and technology may not be patentable. To protect our rights, we require employees, consultants, advisors and collaborators to enter into confidentiality agreements. There can be no assurance, however, that these agreements will provide meaningful protection for our trade secrets, know -how or other proprietary information in the event of any unauthorized use or disclosure. Further, our business may be adversely affected by competitors who independently develop competing technologies, especially if we obtain no, or only narrow, patent protection.

We may be unable to protect our patents and proprietary rights .

Our future success will depend to a significant extent on our ability to:

•         obtain and keep patent protection for our products and technologies on an international basis;

•         enforce our patents to prevent others from using our inventions;

•         maintain and prevent others from using our trade secrets; and

•         operate and commercialize products without infringing on the patents or proprietary rights of others.

We can provide no assurance that our patent rights will afford any competitive advantages and these rights may be challenged or circumvented by third parties. Further, patents may not be issued on any of our pending patent applications in the U.S. or abroad. Because of the extensive time required for development, testing and regulatory review of a product candidate, it is possible that before a product candidate can be commercialized, any related patent may expire, or remain in existence for only a short period following commercialization, reducing or eliminating any advantage of the patent.

If we sue others for infringing our patents, a court may determine that such patents are invalid or unenforceable. Even if the validity of our patent rights is upheld by a court, a court may not prevent the alleged infringement of our patent rights on the grounds that such activity is not covered by our patent claims.

In addition, third parties may sue us for infringing their patents. In the event of a successful claim of infringement against us, we may be required to:

•         defend litigation or administrative proceedings;

•         pay substantial damages;

•         stop using our technologies and methods;

•         stop certain research and development efforts;

•         develop non -infringing products or methods; and

•         obtain one or more licenses from third parties.

If required, we can provide no assurance that we will be able to obtain such licenses on acceptable terms, or at all. If we are sued for infringement, we could encounter substantial delays in development, manufacture and commercialization of our product candidates. Any litigation, whether to enforce our patent rights or to defend against allegations that we infringe third -party rights, will be costly, time consuming, and may distract management from other important tasks.

As is commonplace in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. To the extent our employees are involved in research areas which are similar to those areas in which they were involved at their former employers, we may be subject to claims that such employees and/or we have inadvertently or otherwise used or disclosed the alleged trade secrets or other proprietary information of the former employers. Litigation may be necessary to defend against such claims, which could result in substantial costs and be a distraction to management and which may have a material adverse effect on us, even if we are successful in defending such claims.

We are subject to various government regulations.

The manufacture and sale of human therapeutic and diagnostic products in the U.S., Canada and foreign jurisdictions are governed by a variety of statutes and regulations. These laws require approval of manufacturing facilities, controlled research and testing of products and government review and approval of a submission containing manufacturing, preclinical and clinical data in order to obtain marketing approval based on establishing the safety and efficacy of the product for each use sought, including adherence to current cGMP during production and storage, and control of marketing activities, including advertising and labeling.

VAL -083 and any other products we may develop will require significant development, preclinical and clinical testing and investment of substantial funds prior to its commercialization. The process of obtaining required approvals can be costly and time -consuming , and there can be no assurance that we will successfully develop any future products that will prove to be safe and effective in clinical studies or receive applicable regulatory approvals. Markets other than the U.S. and Canada have similar restrictions. Potential investors and shareholders should be aware of the risks, problems, delays, expenses and difficulties which we may encounter in view of the extensive regulatory environment which controls our business.

We may request priority review for our product candidate in the future. The FDA may not grant priority review for our product candidate. Moreover, even if the FDA designated such product for priority review, that designation may not lead to a faster regulatory review or approval process and, in any event, would not assure FDA approval.

We may be eligible for priority review designation for our product candidate if the FDA determines such product candidate offers major advances in treatment or provides a treatment where no adequate therapy exists. A priority review designation means that the goal for the FDA to review an application is six months, rather than the standard review period of ten months. The FDA has broad discretion with respect to whether or not to grant priority review status to a product candidate, so even if we believe a particular product candidate is eligible for such designation

or status, the FDA may decide not to grant it. Thus, while the FDA has granted priority review to other oncology disease products, our product candidate, should we determine to seek priority review, may not receive similar designation. Moreover, even if our product candidate is designated for priority review, such a designation does not necessarily mean a faster regulatory review process or necessarily confer any advantage with respect to approval compared to conventional FDA procedures. Receiving priority review from the FDA does not guarantee approval within an accelerated timeline or thereafter.

We believe we may in some instances be able to secure approval from the FDA or comparable non-U.S. regulatory authorities to use accelerated development pathways. If we are unable to obtain such approval, we may be required to conduct additional preclinical studies or clinical studies beyond those that we contemplate, which could increase the expense of obtaining, and delay the receipt of, necessary marketing approvals.

We anticipate that we may seek an accelerated approval pathway for our product candidate. Under the accelerated approval provisions in the Federal Food, Drug, and Cosmetic Act, or FDCA, and the FDA’s implementing regulations, the FDA may grant accelerated approval to a product designed to treat a serious or life -threatening condition that provides meaningful therapeutic benefit over available therapies upon a determination that the product has an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. The accelerated approval pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is usually contingent on the sponsor’s agreement to conduct, in a diligent manner, additional post -approval confirmatory studies to verify and describe the drug’s clinical benefit. If such post -approval studies fail to confirm the drug’s clinical benefit, the FDA may withdraw its approval of the drug.

Prior to seeking such accelerated approval, we will seek feedback from the FDA and will otherwise evaluate our ability to seek and receive such accelerated approval. There can also be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit a New Drug Application (“NDA”), for accelerated approval or any other form of expedited development, review or approval. Similarly, there can be no assurance that after subsequent FDA feedback that we will continue to pursue or apply for accelerated approval or any other form of expedited development, review or approval, even if we initially decide to do so. Furthermore, if we decide to submit an application for accelerated approval or under another expedited regulatory designation (e.g., breakthrough therapy designation), there can be no assurance that such submission or application will be accepted or that any expedited development, review or approval will be granted on a timely basis, or at all. The FDA or other non -U .S. authorities could also require us to conduct further studies prior to considering our application or granting approval of any type. A failure to obtain accelerated approval or any other form of expedited development, review or approval for any of our product candidates that we determine to seek accelerated approval for would result in a longer time period to commercialization of such product candidate, could increase the cost of development of such product candidate and could harm our competitive position in the marketplace.

We have conducted, and may in the future conduct, clinical studies for certain of our product candidates at sites outside the United States, and the FDA may not accept data from studies conducted in such locations.

We have conducted and may in the future choose to conduct one or more of our clinical studies outside the United States. Although the FDA may accept data from clinical studies conducted outside the United States, acceptance of this data is subject to certain conditions imposed by the FDA. For example, the clinical study must be well designed and conducted and performed by qualified investigators in accordance with ethical principles. The study population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Generally, the patient population for any clinical studies conducted outside of the United States must be representative of the population for whom we intend to seek approval in the United States. In addition, while these clinical studies are subject to the applicable local laws, FDA acceptance of the data will be dependent upon its determination that the studies also complied with all applicable U.S. laws and regulations. There can be no assurance that the FDA will accept data from studies conducted outside

of the United States. If the FDA does not accept the data from any of our clinical studies that we determine to conduct outside the United States, it would likely result in the need for additional studies, which would be costly and time -consuming and delay or permanently halt our development of the product candidate.

In addition, the conduct of clinical studies outside the United States could have a significant impact on us. Risks inherent in conducting international clinical studies include:

•         foreign regulatory requirements that could restrict or limit our ability to conduct our clinical studies;

•         administrative burdens of conducting clinical studies under multiple foreign regulatory schema;

•         foreign exchange fluctuations; and

•         diminished protection of intellectual property in some countries.

If our clinical studies fail to demonstrate safety and efficacy to the satisfaction of the FDA and comparable non-U.S. regulators, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidate.

We are not permitted to commercialize, market, promote or sell any product candidate in the United States without obtaining marketing approval from the FDA. Comparable non -U .S. regulatory authorities, such as the EMA, impose similar restrictions. We may never receive such approvals. We must complete extensive preclinical development and clinical studies to demonstrate the safety and efficacy of our product candidate in humans before we will be able to obtain these approvals.

Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. We have not previously submitted an NDA to the FDA or similar drug approval filings to comparable non -U .S. regulatory authorities for any product candidate.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us and impair our ability to generate revenues from product sales, regulatory and commercialization milestones and royalties. In addition, if (1) we are required to conduct additional clinical studies or other testing of our product candidate beyond the studies and testing that we contemplate, (2) we are unable to successfully complete clinical studies of our product candidate or other testing, (3) the results of these studies or tests are unfavorable, uncertain or are only modestly favorable, or (4) there are unacceptable safety concerns associated with our product candidate, we, in addition to incurring additional costs, may:

•         be delayed in obtaining marketing approval for our product candidates;

•         not obtain marketing approval at all;

•         obtain approval for indications or patient populations that are not as broad as we intended or desired;

•         obtain approval with labeling that includes significant use or distribution restrictions or significant safety warnings, including boxed warnings;

•         be subject to additional post -marketing testing or other requirements; or

•         be required to remove the product from the market after obtaining marketing approval.

If we experience any of a number of possible unforeseen events in connection with clinical studies of our product candidates, potential marketing approval or commercialization of our product candidates could be delayed or prevented.

We may experience numerous unforeseen events during, or as a result of, clinical studies that could delay or prevent marketing approval of our product candidate, including:

•         clinical studies of our product candidate may produce unfavorable or inconclusive results;

•         we may decide, or regulators may require us, to conduct additional clinical studies or abandon product development programs;

•         the number of patients required for clinical studies of our product candidate may be larger than we anticipate, patient enrollment in these clinical studies may be slower than we anticipate or participants may drop out of these clinical studies at a higher rate than we anticipate;

•         data safety monitoring committees may recommend suspension, termination or a clinical hold for various reasons, including concerns about patient safety;

•         regulators or IRBs may suspend or terminate the study or impose a clinical hold for various reasons, including noncompliance with regulatory requirements or concerns about patient safety;

•         patients with serious, life -threatening diseases included in our clinical studies may die or suffer other adverse medical events for reasons that may not be related to our product candidate;

•         participating patients may be subject to unacceptable health risks;

•         patients may not complete clinical studies due to safety issues, side effects, or other reasons;

•         changes in regulatory requirements and guidance may occur, which require us to amend clinical study protocols to reflect these changes;

•         our third -party contractors, including those manufacturing our product candidate or components or ingredients thereof or conducting clinical studies on our behalf, may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner or at all;

•         regulators or institutional review boards, or IRBs may not authorize us or our investigators to commence a clinical study or conduct a clinical study at a prospective study site;

•         we may experience delays in reaching or fail to reach agreement on acceptable clinical study contracts or clinical study protocols with prospective study sites;

•         patients who enroll in a clinical study may misrepresent their eligibility to do so or may otherwise not comply with the clinical study protocol, resulting in the need to drop the patients from the clinical study, increase the needed enrollment size for the clinical study or extend the clinical study’s duration;

•         we may have to suspend or terminate clinical studies of our product candidate for various reasons, including a finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of a product candidate;

•         regulators or IRBs may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or their respective standards of conduct, a finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of the product candidate or findings of undesirable effects caused by a chemically or mechanistically similar drug or drug candidate;

•         the FDA or comparable non -U .S. regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or facilities of third -party manufacturers with which we enter into agreements for clinical and commercial supplies;

•         the FDA or comparable non -U .S. regulatory authorities may disagree with our clinical study design or our interpretation of data from preclinical studies and clinical studies;

•         the supply or quality of raw materials or manufactured product candidate or other materials necessary to conduct clinical studies of our product candidate may be insufficient, inadequate, delayed, or not available at an acceptable cost, or we may experience interruptions in supply; and

•         the approval policies or regulations of the FDA or comparable non -U .S. regulatory authorities may significantly change in a manner rendering our clinical data insufficient to obtain marketing approval.

Product development costs for us will increase if we experience delays in testing or pursuing marketing approvals and we may be required to obtain additional funds to complete clinical studies and prepare for possible commercialization of our product candidate. We do not know whether any preclinical tests or clinical studies will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant preclinical or

clinical study delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidate or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidate and may harm our business and results of operations. In addition, many of the factors that cause, or lead to, clinical study delays may ultimately lead to the denial of marketing approval of our product candidate.

If we experience delays or difficulties in the enrollment of patients in clinical studies, we may not achieve our clinical development on our anticipated timeline, or at all, and our receipt of necessary regulatory approvals could be delayed or prevented.

We may not be able to initiate or continue clinical studies for VAL -083 or any other product candidate if we are unable to locate and enroll a sufficient number of eligible patients to participate in clinical studies. Patient enrollment is a significant factor in the timing of clinical studies, and is affected by many factors, including:

•         the size and nature of the patient population;

•         the severity of the disease under investigation;

•         the proximity of patients to clinical sites;

•         the eligibility criteria for the study;

•         the design of the clinical study;

•         efforts to facilitate timely enrollment;

•         competing clinical studies; and

•         clinicians’ and patients’ perceptions as to the potential advantages and risks of the drug being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating.

Our inability to enroll a sufficient number of patients for our clinical studies could result in significant delays or may require us to abandon one or more clinical studies altogether. Enrollment delays in our clinical studies may result in increased development costs for our product candidate, delay or halt the development of and approval processes for our product candidate and jeopardize our ability to achieve our clinical development timeline and goals, including the dates by which we will commence, complete and receive results from clinical studies. Enrollment delays may also delay or jeopardize our ability to commence sales and generate revenues from our product candidate. Any of the foregoing could cause our value to decline and limit our ability to obtain additional financing, if needed.

Positive results in previous clinical studies of VAL-083 may not be replicated in future clinical studies, which could result in development delays or a failure to obtain marketing approval.

Positive results in previous clinical studies of VAL -083 may not be predictive of similar results in future clinical studies. Also, interim results during a clinical study do not necessarily predict final results. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late -stage clinical studies even after achieving promising results in early -stage development. Accordingly, the results from the completed preclinical studies and clinical studies for VAL -083 may not be predictive of the results we may obtain in later stage studies. Our clinical studies may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical studies. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical studies have nonetheless failed to obtain FDA or EMA, or other regulatory agency, approval for their products.

FDA approval of VAL-083 or future product candidates may be denied.

There can be no assurance that the FDA will ultimately approve our NDA. The FDA may deny approval of VAL -083 for many reasons, including:

•         we may be unable to demonstrate to the satisfaction of the FDA that our products are safe and effective for its intended uses;

•         the FDA may disagree with our interpretation of data from the clinical studies;

•         we may be unable to demonstrate that any clinical or other benefits our products outweigh any safety or other perceived risks; or

•         we may not be able to successfully address any other issues raised by the FDA.

If VAL -083 fails to receive FDA approval, our business and prospects will be materially adversely impacted.

We expect to rely on orphan drug status to develop and commercialize our product candidate, but our orphan drug designations may not confer marketing exclusivity or other expected commercial benefits as anticipated.

Market exclusivity afforded by orphan drug designation is generally offered as an incentive to drug developers to invest in developing and commercializing products for unique diseases that impact a limited number of patients. The FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States. Qualification to maintain orphan drug status is generally monitored by the regulatory authorities during the orphan drug exclusivity period, currently seven years from the date of approval in the United States.

We have been granted orphan drug designation in the United States for GBM, ovarian cancer, and medulloblastoma, and in Europe for GBM. We expect to rely on orphan drug exclusivity for our product candidate. It is possible that the incidence and prevalence numbers for GBM could change. Should the incidence and prevalence of GBM patients materially increase, it is possible that the orphan drug designation, and related market exclusivity, in the United States could be lost. Further, while we have been granted this orphan designation, the FDA can still approve different drugs for use in treating the same indication or disease, which would create a more competitive market for us and our revenues will be diminished.

Further, it is possible that another company also holding orphan drug designation for the same product candidate will receive marketing approval for the same indication before we do. If that were to happen, our applications for that indication may not be approved until the competing company’s period of exclusivity expires. Even if we are the first to obtain marketing authorization for an orphan drug indication, there are circumstances under which a competing product may be approved for the same indication during the seven -year period of marketing exclusivity, such as if the later product is shown to be clinically superior to the orphan product, or if the later product is deemed a different product than ours. Further, the seven -year marketing exclusivity would not prevent competitors from obtaining approval of the same product candidate as ours for indications other than those in which we have been granted orphan drug designation, or for the use of other types of products in the same indications as our orphan product.

If the market opportunities for our product candidate are smaller than we believe they are, our revenues may be adversely affected and our business may suffer. Because the target patient populations of our product candidate are small, we must be able to successfully identify patients and capture a significant market share to achieve and maintain profitability.

We focus our research and product development on treatments for orphan cancer indications. Our projections of both the number of people who have failed other therapies or have limited medical options, are based on estimates. These estimates may prove to be incorrect and new studies may change the estimated incidence or prevalence. The number of patients in the United States, Europe and elsewhere may turn out to be lower than expected or may not be otherwise amenable to treatment with our products, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business. Additionally, because our target patient populations are small, we will be required to capture a significant market share to achieve and maintain profitability.

We may be required to suspend or discontinue clinical studies due to unexpected side effects or other safety risks that could preclude approval of our products.

Our clinical studies may be suspended at any time for a number of reasons. For example, we may voluntarily suspend or terminate our clinical studies if at any time we believe that they present an unacceptable risk to the clinical study patients. In addition, the FDA or other regulatory agencies may order the temporary or permanent discontinuation

of our clinical studies at any time if they believe that the clinical studies are not being conducted in accordance with applicable regulatory requirements or that they present an unacceptable safety risk to the clinical study patients.

Administering any product candidate to humans may produce undesirable side effects. These side effects could interrupt, delay or halt clinical studies of our product candidates and could result in the FDA or other regulatory authorities denying further development or approval of our product candidates for any or all targeted indications. Ultimately, some or all of our product candidates may prove to be unsafe for human use. Moreover, we could be subject to significant liability if any volunteer or patient suffers, or appears to suffer, adverse health effects or even death as a result of participating in our clinical studies.

We may not receive regulatory approvals for our product candidate or there may be a delay in obtaining such approvals.

Our product and our ongoing development activities are subject to regulation by regulatory authorities in the countries in which we or our collaborators and distributors wish to test, manufacture or market our products. For instance, the FDA will regulate the product in the U.S. and equivalent authorities, such as the EMA, will regulate in Europe. Regulatory approval by these authorities will be subject to the evaluation of data relating to the quality, efficacy and safety of the product for its proposed use, and there can be no assurance that the regulatory authorities will find our data sufficient to support product approval of VAL -083 or any future product candidates.

The time required to obtain regulatory approval varies between countries. The FDA is required to facilitate the development and expedite the review of drugs and biologics that are intended for the treatment of a serious or life -threatening disease or condition and which demonstrate the potential to address unmet medical needs for the condition. Filling an unmet medical need is defined as providing a therapy where none exists or providing a therapy that may be potentially better than available therapy. Under the fast track program, the sponsor of a new drug or biologic candidate may request the FDA to designate the product for a specific indication as a fast track product concurrent with or after the filing of the IND for the product candidate. The FDA must determine if the product candidate qualifies for fast track designation within 60 days after receipt of the sponsor’s request. In the U.S., for products without “Fast Track” status, it can take over eighteen (18) months after submission of an application for product approval to receive the FDA’s decision. Even with Fast Track status, FDA review and decision can take over twelve (12) months.

In December 2017, the FDA granted Fast Track designation for VAL -083 in rGBM.

Different regulators may impose their own requirements and may refuse to grant, or may require additional data before granting, an approval, notwithstanding that regulatory approval may have been granted by other regulators. Regulatory approval may be delayed, limited or denied for a number of reasons, including insufficient clinical data, the product not meeting safety or efficacy requirements or any relevant manufacturing processes or facilities not meeting applicable requirements as well as case load at the regulatory agency at the time.

We may fail to comply with regulatory requirements .

Our success will be dependent upon our ability, and our collaborative partners’ abilities, to maintain compliance with regulatory requirements, including cGMP, and safety reporting obligations. The failure to comply with applicable regulatory requirements can result in, among other things, fines, injunctions, civil penalties, total or partial suspension of regulatory approvals, refusal to approve pending applications, recalls or seizures of products, operating and production restrictions and criminal prosecutions.

Even if our product candidate receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success and the market opportunity for the product candidate may be smaller than we estimate.

We have never commercialized a product. Even if VAL -083 or any other product candidate is approved by the appropriate regulatory authorities for marketing and sale, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third -party payors and others in the medical community. For example, physicians are often reluctant to switch their patients from existing therapies even when new and potentially more effective or convenient treatments enter the market. Further, patients often acclimate to the therapy that they are currently taking and do not want to switch unless their physicians recommend switching products or they are required to switch therapies due to lack of reimbursement for existing therapies.

Efforts to educate the medical community and third -party payors on the benefits of our product candidate may require significant resources and may not be successful. If our product candidate is approved but does not achieve an adequate level of market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of VAL -083 or any other product candidate, if approved for commercial sale, will depend on a number of factors, including:

•         the efficacy and safety of the product;

•         the potential advantages of the product compared to alternative treatments;

•         the prevalence and severity of any side effects;

•         the clinical indications for which the product is approved;

•         whether the product is designated under physician treatment guidelines as a first -line therapy or as a second- or third -line therapy;

•         limitations or warnings, including distribution or use restrictions, contained in the product’s approved labeling;

•         our ability to offer the product for sale at competitive prices;

•         our ability to establish and maintain pricing sufficient to realize a meaningful return on our investment;

•         the product’s convenience and ease of administration compared to alternative treatments;

•         the willingness of the target patient population to try, and of physicians to prescribe, the product;

•         the strength of sales, marketing and distribution support;

•         the approval of other new products for the same indications;

•         changes in the standard of care for the targeted indications for the product;

•         the timing of market introduction of our approved products as well as competitive products and other therapies;

•         availability and amount of reimbursement from government payors, managed care plans and other third -party payors;

•         adverse publicity about the product or favorable publicity about competitive products; and

•         potential product liability claims.

The potential market opportunities for our product candidate are difficult to estimate precisely. Our estimates of the potential market opportunities are predicated on many assumptions, including industry knowledge and publications, third -party research reports and other surveys. While we believe that our internal assumptions are reasonable, these assumptions involve the exercise of significant judgment on the part of our management, are inherently uncertain and the reasonableness of these assumptions has not been assessed by an independent source. If any of the assumptions proves to be inaccurate, the actual markets for our product candidate could be smaller than our estimates of the potential market opportunities.

If our product candidate receives marketing approval and we, or others, later discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, our ability to market the drug could be compromised.

Clinical studies of our product candidate are conducted in carefully defined subsets of patients who have agreed to enter into clinical studies. Consequently, it is possible that our clinical studies may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If, following approval of our product candidate, we, or others, discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, any of the following adverse events could occur:

•         regulatory authorities may withdraw their approval of the drug or seize the drug;

•         we may be required to recall the drug or change the way the drug is administered;

•         additional restrictions may be imposed on the marketing of, or the manufacturing processes for, the particular drug;

•         we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

•         regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;

•         we may be required to create a Medication Guide outlining the risks of the previously unidentified side effects for distribution to patients;

•         we could be sued and held liable for harm caused to patients;

•         the drug may become less competitive; and

•         our reputation may suffer.

Any of these events could have a material and adverse effect on our operations and business and could adversely impact our stock price.

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, qualification testing, post-approval clinical data, labeling and promotional activities for such product, will be subject to continual and additional requirements of the FDA and other regulatory authorities.

These requirements include submissions of safety and other post -marketing information, reports, registration and listing requirements, good manufacturing practices, or GMP requirements relating to quality control, quality assurance and corresponding maintenance of records and documents, and recordkeeping. Even if marketing approval of our product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to conditions of approval, or contain requirements for costly post -marketing testing and surveillance to monitor the safety or efficacy of the product. The FDA closely regulates the post -approval marketing and promotion of pharmaceutical products to ensure such products are marketed only for the approved indications and in accordance with the provisions of the approved labeling.

In addition, later discovery of previously unknown problems with our products, manufacturing processes, or failure to comply with regulatory requirements, may lead to various adverse results, including:

•         restrictions on such products, manufacturers or manufacturing processes;

•         restrictions on the labeling or marketing of a product;

•         restrictions on product distribution or use;

•         requirements to conduct post -marketing clinical studies;

•         requirements to institute a risk evaluation mitigation strategy, or REMS, to monitor safety of the product post -approval ;

•         warning letters issued by the FDA or other regulatory authorities;

•         withdrawal of the products from the market;

•         refusal to approve pending applications or supplements to approved applications that we submit;

•         recall of products, fines, restitution or disgorgement of profits or revenue;

•         suspension, revocation or withdrawal of marketing approvals;

•         refusal to permit the import or export of our products; and

•         injunctions or the imposition of civil or criminal penalties.

If we are unable to establish sales, marketing and distribution capabilities or enter into acceptable sales, marketing and distribution arrangements with third parties, we may not be successful in commercializing any product candidates that we develop, if and when those product candidates are approved.

We do not have a sales, marketing or distribution infrastructure and have limited experience in the sale, marketing or distribution of pharmaceutical products. To achieve commercial success for any approved product, we must either develop a sales and marketing organization, outsource these functions to third parties, or license our product candidates to others. If approved, we may seek to license VAL -083 to a large pharmaceutical company with greater resources and experience than us. We may not be able license the VAL -083 on reasonable terms, if at all. The development of sales, marketing and distribution capabilities will require substantial resources, will be time -consuming and could delay any product launch. We expect that we will commence the development of these capabilities prior to receiving approval of our product candidate. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing and distribution capabilities is delayed or does not occur for any reason, we could have prematurely or unnecessarily incurred these commercialization costs. Such a delay may be costly, and our investment could be lost if we cannot retain or reposition our sales and marketing personnel. In addition, we may not be able to hire or retain a sales force in the United States that is sufficient in size or has adequate expertise in the medical markets that we plan to target. If we are unable to establish or retain a sales force and marketing and distribution capabilities, our operating results may be adversely affected. If a potential partner has development or commercialization expertise that we believe is particularly relevant to our product candidate, then we may seek to collaborate with that potential partner even if we believe we could otherwise develop and commercialize the product independently.

We expect to seek one or more strategic partners for commercialization of our product candidate outside the United States. As a result of entering into arrangements with third parties to perform sales, marketing and distribution services, our product revenues or the profitability of these product revenues may be lower, perhaps substantially lower, than if we were to directly market and sell products in those markets. Furthermore, we may be unsuccessful in entering into the necessary arrangements with third parties or may be unable to do so on terms that are favorable to us. In addition, we may have little or no control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively.

If we do not establish sales and marketing capabilities, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidate.

We face substantial competition from other pharmaceutical and biotechnology companies and our operating results may suffer if we fail to compete effectively.

The development and commercialization of new drug products is highly competitive. We expect that we will face significant competition from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide with respect to VAL -083 and any other product candidates that we may seek to develop or commercialize in the future. Specifically, due to the large unmet medical need, global demographics and relatively attractive reimbursement dynamics, the oncology market is fiercely competitive and there are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of product candidates for the treatment of cancer. Our competitors may succeed in developing, acquiring or licensing technologies and drug products that are more effective, have fewer or more tolerable side effects or are less costly than any product candidates that we are currently developing or that we may develop, which could render our product candidates obsolete and noncompetitive.

All of the top ten global pharmaceutical companies and many of the mid -size pharmaceutical companies have a strong research and development and commercial presence in oncology. Smaller companies also focus on oncology, including companies such as ARIAD Pharmaceuticals, Inc., Agios Pharmaceuticals, Inc., BIND Therapeutics, Inc., Clovis Oncology, Inc., Endocyte, Inc., Epizyme, Inc., ImmunoGen, Inc., Incyte Corporation, Infinity Pharmaceuticals, Inc., MacroGenics, Inc., Merrimack Pharmaceuticals, Inc., OncoMed Pharmaceuticals, Inc., Onconova Therapeutics, Inc., Pharmacyclics, Inc., Puma Biotechnology, Inc., Seattle Genetics, Inc. and TESARO, Inc.

Several companies are marketing and developing oncology immunotherapy products. Companies with approved marketed oncology products for GBM are Merck (Temodar ® ) and Genentech (Avastin ® ). Companies with oncology immunotherapy product candidates in clinical development include, but are not limited to, Northwest Biotherapeutics (DCVax -L ), Celldex Therapeutics (Rindopepimut (CDX -110 )) and ImmunoCellular Therapeutics (ICT -107 ).

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 any products that we may develop. Our competitors also may obtain FDA or other marketing approval for their products before we are able to obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Many of our existing and potential future competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical studies, obtaining marketing 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 or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical study sites and patient registration for clinical studies, as well as in acquiring technologies complementary to, or necessary for, our programs.

If we are unable to or delayed in obtaining state regulatory licenses for the distribution of our product, we would not be able to sell our product candidate.

The majority of states require manufacturer and/or wholesaler licenses for the sale and distribution of drugs into that state. The application process is complicated, time consuming and requires dedicated personnel or a third -party to oversee and manage. If we are delayed in obtaining these state licenses, or denied the licenses, even with FDA approval, we would not be able to sell or ship product into that state which would adversely affect our sales and revenues.

We rely on key personnel and, if we are unable to retain or motivate key personnel or hire qualified personnel, we may not be able to grow effectively.

We are dependent on certain members of our management, scientific and drug development staff and consultants, the loss of services of one or more of whom could materially adversely affect us.

We currently have two full -time employees, and retain the services of approximately 15 persons on an independent contractor/consultant and contract -employment basis. Our ability to manage growth effectively will require us to continue to implement and improve our management systems and to recruit and train new employees. Although we have done so in the past and expect to do so in the future, there can be no assurance that we will be able to successfully attract and retain skilled and experienced personnel.

Our success depends in large part upon our ability to attract and retain highly qualified personnel. We compete in our hiring efforts with other pharmaceutical and biotechnology companies, as well as universities and nonprofit research organizations, and we may have to pay higher salaries to attract and retain personnel, which would be very costly.

We may be subject to foreign exchange fluctuation.

Our functional and reporting currency is the United States dollar. We maintain bank accounts in United States and Canadian dollars. A portion of our expenditures are in foreign currencies, most notably in Canadian dollars, and therefore we are subject to foreign currency fluctuations, which may, from time to time, impact our financial position and results. We may enter into hedging arrangements under specific circumstances, typically through the use of forward or futures currency contracts, to minimize the impact of increases in the value of the Canadian dollar. In order to minimize our exposure to foreign exchange fluctuations we may hold sufficient Canadian dollars to cover our expected Canadian dollar expenditures.

Product liability lawsuits against us could divert our resources, cause us to incur substantial liabilities and limit commercialization of any products that we may develop.

We face an inherent risk of product liability claims as a result of the clinical testing of our product candidate despite obtaining appropriate informed consents from our clinical study participants. We will face an even greater risk if we commercially sell any product that we may develop. For example, we may be sued if any product we develop

allegedly causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidate. Regardless of the merits or eventual outcome, liability claims may result in:

•         decreased demand for our product candidate or products that we may develop;

•         injury to our reputation and significant negative media attention;

•         withdrawal of clinical study participants;

•         significant costs to defend resulting litigation;

•         substantial monetary awards to study participants or patients;

•         loss of revenue;

•         reduced resources of our management to pursue our business strategy; and

•         the inability to commercialize any products that we may develop.

Although we maintain general liability insurance, this insurance may not fully cover potential liabilities that we may incur. The cost of any product liability litigation or other proceeding, even if resolved in our favor, could be substantial. We will need to increase our insurance coverage if and when we begin selling any product candidate that receives marketing approval. In addition, insurance coverage is becoming increasingly expensive. If we are unable to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims, it could prevent or inhibit the development and commercial production and sale of our product candidate, which could adversely affect our business, financial condition, results of operations and prospects.

Risks Related to Our Dependence on Third Parties

We rely on third parties to conduct clinical studies for our product candidate. Any failure by a third-party to meet its obligations with respect to the clinical development of our product candidate may delay or impair our ability to obtain regulatory approval for our product candidate.

We rely on academic institutions and private oncology centers to conduct our clinical studies. Our reliance on third parties to conduct clinical studies could, depending on the actions of such third parties, jeopardize the validity of the clinical data generated and adversely affect our ability to obtain marketing approval from the FDA or other applicable regulatory authorities.

Such clinical study arrangements provide us with information rights with respect to the clinical data, including access to and the ability to use and reference the data, including for our own regulatory filings, resulting from the clinical studies. If investigators or institutions breach their obligations with respect to the clinical studies of our product candidate, or if the data proves to be inadequate, then our ability to design and conduct any future clinical studies may be adversely affected.

We rely, and expect to continue to rely, on third parties to conduct our clinical studies, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such studies.

We currently rely on third -party clinical research organizations, or CROs, to conduct our clinical studies. We expect to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions and clinical investigators, to conduct our clinical studies. Our agreements with these third parties generally allow the third -party to terminate the agreement at any time. If we are required to enter into alternative arrangements because of any such termination the introduction of our product candidates to market could be delayed.

Our reliance on these third parties for research and development activities will reduce our control over these activities but will not relieve us of our responsibilities. For example, we design our clinical studies and will remain

responsible for ensuring that each of our clinical studies are conducted in accordance with the general investigational plan and protocols for the study. Moreover, the FDA requires us to comply with standards, commonly referred to as good clinical practices, or GCPs, for conducting, recording and reporting the results of clinical studies to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of study participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. We also are required to register ongoing clinical studies and post the results of completed clinical studies on a government -sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical studies in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates.

We also expect to rely on other third parties to store and distribute drug supplies for our clinical studies. Any performance failure on the part of our distributors could delay clinical development or marketing approval of our product candidate or commercialization of our products, producing additional losses and depriving us of potential product revenue.

We may seek to enter into collaborations with third parties for the development and commercialization of our product candidate. If we fail to enter into such collaborations, or such collaborations are not successful, we may not be able to capitalize on the market potential of our product candidate.

We may seek third -party collaborators for development and commercialization of our product candidate. Our likely collaborators for any marketing, distribution, development, licensing or broader collaboration arrangements include large and mid -size pharmaceutical companies, regional and national pharmaceutical companies, non -profit organizations, government agencies, and biotechnology companies. We are currently party to a limited number of such arrangements and have limited control over the amount and timing of resources that our collaborators dedicate to the development or commercialization of our product candidate. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements.

Collaborations involving our product candidate currently pose, and will continue to pose, the following risks to us:

•         collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;

•         collaborators may not pursue development and commercialization of our product candidate or may elect not to continue or renew development or commercialization programs based on preclinical or clinical study results, changes in the collaborators’ strategic focus or available funding, or external factors such as an acquisition that diverts resources or creates competing priorities;

•         collaborators may delay clinical studies, provide insufficient funding for a clinical study program, stop a clinical study or abandon a product candidate, repeat or conduct new clinical studies or require a new formulation of a product candidate for clinical testing;

•         collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidate if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours;

•         collaborators with marketing and distribution rights to one or more products may not commit sufficient resources to the marketing and distribution of such product or products;

•         collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;

•         collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;

•         disputes may arise between the collaborators and us that result in the delay or termination of the research, development or commercialization of our product candidate or that result in costly litigation or arbitration that diverts management attention and resources; and

•         collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable product candidates.

Collaboration agreements may not lead to development or commercialization of our product candidate in the most efficient manner or at all. If a collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our product development or commercialization program could be delayed, diminished or terminated.

If we are not able to establish collaborations, we may have to alter our development and commercialization plans.

Our drug development programs and the potential commercialization of our product candidate will require substantial additional cash to fund expenses. We may decide to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of our product candidate.

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of preclinical studies or clinical studies, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under future license agreements from entering into agreements on certain terms with potential collaborators. Collaborations are complex and time -consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of our product candidate, reduce or delay its development program, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidate or bring it to market and generate product revenue.

We currently manufacture our clinical supplies at a single location. Any disruption at this facility could adversely affect our business and results of operations.

We have engaged a single manufacturer to produce GMP active pharmaceutical ingredient and a single manufacturer to produce drug product for our clinical studies. In addition, we have relied on our manufacturing partner, Guangxi Wuzhou Pharmaceutical Company, for the manufacture of clinical supply of VAL -083 for our preclinical and Phase 2 clinical studies to -date . If our manufacturer’s facility were damaged or destroyed, or otherwise subject to disruption, it would require substantial lead -time to replace our clinical supply. In such event, we would be forced to rely entirely on other third -party contract manufacturers for an indefinite period of time. We do not currently have established relationships with any back -up manufacturers. At this time no drug product has been manufactured by a third -party back -up manufacturer. Any disruptions or delays by our third -party manufacturers or Guangxi Wuzhou Pharmaceutical Company or their failure to meet regulatory compliance could impair our ability to develop VAL -083 , which would adversely affect our business and results of operations.

We rely on these third -party manufacturers to provide drug product supply for our clinical studies. There is no assurance that such a supplier will be able to meet our needs from a technical, timing, or cost -effective manner. Our failure to enter into appropriate agreements with such a third -party manufacturer would delay, or halt, our clinical studies.

We may become subject to liabilities related to risks inherent in working with hazardous materials.

Our discovery and development processes involve the controlled use of hazardous and radioactive materials. We are subject to federal, provincial and local laws and regulations governing the use, manufacture, storage, handling and disposal of such materials and certain waste products. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by such laws and regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources. We are not specifically insured with respect to this liability. Although we believe that we are in compliance in all material respects with applicable environmental laws and regulations and currently do not expect to make material capital expenditures for environmental control facilities in the near -term , there can be no assurance that we will not be required to incur significant costs to comply with environmental laws and regulations in the future, or that our operations, business or assets will not be materially adversely affected by current or future environmental laws or regulations.

Risks Related to Our Common Stock

The market price of our common stock is, and is likely to continue to be, highly volatile and subject to wide fluctuations .

The market price of our common stock is highly volatile and could be subject to wide fluctuations in response to a number of factors that are beyond our control, including:

•         variations in our quarterly operating results;

•         announcements that our revenue or income are below analysts’ expectations;

•         general economic slowdowns;

•         sales of large blocks of our common stock; and

•         announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments.

Because we became public by means of a reverse acquisition, we may not be able to attract, or maintain, the attention of brokerage firms.

Because we became public through a “reverse acquisition”, securities analysts of brokerage firms may not provide or continue to provide coverage of us since there is little incentive to brokerage firms to recommend the purchase of our common stock. No assurance can be given that brokerage firms will want to conduct any follow -on offerings on behalf of us in the future.

Voting power of our shareholders is highly concentrated by insiders.

Our officers, directors, and 5% shareholders control, either directly or indirectly, a substantial portion of our voting securities. Therefore, our management may significantly affect the outcome of all corporate actions and decisions for an indefinite period of time including election of directors, amendment of charter documents and approval of mergers and other significant corporate transactions.

We do not intend to pay dividends on our common stock for the foreseeable future.

We have paid no dividends on our common stock to date and we do not anticipate paying any dividends to holders of our common stock in the foreseeable future. While our future dividend policy will be based on the operating results and capital needs of the business, we currently anticipate that any earnings will be retained to finance our future expansion and for the implementation of our business plan. Investors should take note of the fact that a lack of a dividend can further affect the market value of our common stock, and could significantly affect the value of any investment in us.

Our articles of incorporation allow for our board to create new series of preferred stock without further approval by our stockholders, which could adversely affect the rights of the holders of our common stock.

Our Board of Directors has the authority to fix and determine the relative rights and preferences of preferred stock. Our Board of Directors has the authority to issue up to 5,000,000 shares of our preferred stock (of which 1 share has been designated Special Voting Preferred Stock and is issued and outstanding, 278,530 shares have been designated Series A Preferred Stock and are issued and outstanding, and 1,000,000 shares have been designated as Series B Preferred Stock, of which 673,613 shares are issued and outstanding, as of June 6, 2019) without further stockholder approval. As a result, our Board of Directors could authorize the issuance of additional series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of our common stock. In addition, our Board of Directors could authorize the issuance of a series of preferred stock that has greater voting power than our common stock or that is convertible into our common stock, which could decrease the relative voting power of our common stock or result in dilution to our existing stockholders. Although we have no present intention to issue any additional shares of preferred stock or to create any additional series of preferred stock, we may issue such shares in the future.

Our issuance of common stock upon exercise of warrants, Performance Share Units, or options, exchange of Exchangeable Shares, or conversion of Series B Preferred Stock may depress the price of our common stock.

As of June 6, 2019, we had 3,825,227 shares of common stock issued and outstanding, 9,063 shares of common stock issuable upon exchange of the Exchangeable Shares of Exchangeco (which entitle the holder to require Exchangeco to redeem (or, at the option of us or Callco, to have us or Callco purchase) the Exchangeable Shares, and upon such redemption or purchase to receive an equal number of shares of our common stock) (the Exchangeable Shares are recognized on an as -exchanged for common stock basis for financial statement purposes), outstanding warrants to purchase 1,669,803 shares of common stock, outstanding Series B convertible preferred shares that are convertible into 168,427 shares of common stock and outstanding options to purchase 292,683 shares of common stock. All Exchangeable Shares, warrants, and options are convertible or exercisable into one share of common stock. Each share of Series B preferred stock is convertible into 0.25 shares of common stock. The issuance of shares of common stock upon exercise of outstanding warrants or options or exchange of Exchangeable Shares could result in substantial dilution to our stockholders, which may have a negative effect on the price of our common stock.

Risks Related to the Rights Offering

Our management will have broad discretion over the use of the net proceeds from this offering, you may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

Your interest in our company may be diluted as a result of this Rights Offering.

Stockholders and warrant holders who do not fully exercise their Subscription Rights should expect that they will, at the completion of this offering, own a smaller proportional interest in our company on a fully -diluted basis than would otherwise be the case had they fully exercised their Subscription Rights. Further, the shares issuable upon the exercise of the Warrants to be issued pursuant to the Rights Offering will dilute the ownership interest of stockholders not participating in this offering or holders of Warrants who have not exercised them.

Further, if you purchase Units in this offering at the Subscription Price, you may suffer immediate and substantial dilution in the net tangible book value of our common stock. See “Dilution” in this prospectus for a more detailed discussion of the dilution which may incur in connection with this offering.

Completion of the Rights Offering is not subject to us raising a minimum offering amount.

Completion of the Rights Offering is not subject to us raising a minimum offering amount and, therefore, proceeds may be insufficient to meet our objectives, thereby increasing the risk to investors in this offering, including investing in a company that continues to require capital. See “Use of Proceeds.”

This Rights Offering may cause the trading price of our common stock to decrease.

The Subscription Price, together with the number of shares of common stock issuable upon conversion of the Preferred Stock and Warrants we propose to issue and ultimately will issue if this Rights Offering is completed, may result in an immediate decrease in the market price of our common stock. This decrease may continue after the completion of this Rights Offering. If that occurs, you may have committed to buy shares of our common stock at a price greater than the prevailing market price. We cannot predict the effect, if any, that the availability of shares for future sale represented by the Warrants issued in connection with the Rights Offering will have on the market price of our common stock from time to time. Further, if a substantial number of Subscription Rights are exercised and the holders of the shares received upon exercise of those Subscription Rights or the related Warrants choose to sell some or all of the shares underlying the Subscription Rights or the related Warrants, the resulting sales could depress the market price of our common stock.

Holders of our Warrants will have no rights as a common stockholder until such holders exercise their Warrants and acquire our common stock.

Until holders of Warrants acquire shares of our common stock upon exercise of the Warrants, holders of Warrants will have no rights with respect to the shares of our common stock underlying such Warrants. Upon exercise of the Warrants, the holders thereof will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

If we terminate this offering for any reason, we will have no obligation other than to return subscription monies within 10 business days.

We may decide, in our sole discretion and for any reason, to cancel or terminate the Rights Offering at any time prior to the expiration date. If this offering is cancelled or terminated, we will have no obligation with respect to Subscription Rights that have been exercised except to return within 10 business days, without interest or deduction, all subscription payments deposited with the Subscription Agent. If we terminate this offering and you have not exercised any Subscription Rights, such Subscription Rights will expire and be worthless.

The Subscription Price determined for this offering is not an indication of the fair value of our common stock.

In determining the Subscription Price, our board of directors considered a number of factors, including, but not limited to, our need to raise capital in the near term to continue our operations, the current and historical trading prices of our common stock, a price that would increase the likelihood of participation in the Rights Offering, the cost of capital from other sources, the value of the Preferred Stock and Warrants being issued as components of the Unit, and comparable precedent transactions. The Subscription Price does not necessarily bear any relationship to any established criteria for value. No valuation consultant or investment banker has opined upon the fairness or adequacy of the Subscription Price. You should not consider the Subscription Price as an indication of the value of our company or our common stock.

If you do not act on a timely basis and follow subscription instructions, your exercise of Subscription Rights may be rejected.

Holders of Subscription Rights who desire to purchase shares of our Preferred Stock and Warrants in this offering must act on a timely basis to ensure that all required forms and payments are actually received by the Subscription Agent prior to 5:00 p.m., New York City time, on the expiration date, unless extended. If you are a beneficial owner of shares of common stock or participating warrants and you wish to exercise your Subscription Rights, you must act promptly to ensure that your broker, dealer, bank, trustee or other nominee acts for you and that all required forms and payments are actually received by your broker, dealer, bank, trustee or other nominee in sufficient time to deliver such forms and payments to the Subscription Agent to exercise the Subscription Rights granted in

this offering that you beneficially own prior to 5:00 p.m., New York City time on the expiration date, as may be extended. We will not be responsible if your broker, dealer, bank, trustee or other nominee fails to ensure that all required forms and payments are actually received by the Subscription Agent prior to 5:00 p.m., New York City time, on the expiration date.

If you fail to complete and sign the required subscription forms, send an incorrect payment amount, or otherwise fail to follow the subscription procedures that apply to your exercise in this Rights Offering, the Subscription Agent may, depending on the circumstances, reject your subscription or accept it only to the extent of the payment received. Neither we nor the Subscription Agent undertakes to contact you concerning an incomplete or incorrect subscription form or payment, nor are we under any obligation to correct such forms or payment. We have the sole discretion to determine whether a subscription exercise properly follows the subscription procedures.

You may not receive all of the Units for which you subscribe.

While we are distributing to holders of our common stock and certain outstanding warrants, one Subscription Rights for every share of common stock (including each share of common stock issuable upon exercise of certain outstanding warrants) owned on the Record Date, we are only seeking to raise $1.86 million dollars in gross proceeds in this Rights Offering. As a result, based on 2,653,689 shares of common stock outstanding as of May 21, 2019 and 585,626 shares of common stock issuable upon exercise of certain outstanding warrants, we would grant Subscription Rights to acquire 3,239,315 Units but will only accept subscriptions for 1,860 Units. Over -Subscription Privileges will be allocated pro rata among Rights holders who over -subscribed , based on the number of over -subscription Units to which they have subscribed. We cannot guarantee that you will receive any, or the entire amount, of Units for which you subscribed. If for any reason the amount of Units allocated to you is less than you have subscribed for, then the excess funds held by the Subscription Agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

Unless we otherwise agree in writing, a person or entity, together with related persons or entities, may not exercise Subscription Rights (including Over -Subscription Privileges) to purchase Units that, when aggregated with their existing ownership, would result in such person or entity, together with any related persons or entities, owning in excess of 19.99% of our issued and outstanding shares of common stock following the closing of the transactions contemplated by this Rights Offering. If the amount of shares allocated to you is less than your subscription request, then the excess funds held by the Subscription Agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

If you make payment of the Subscription Price by personal check, your check may not clear in sufficient time to enable you to purchase shares in this Rights Offering.

Any personal check used to pay for shares and Warrants to be issued in this Rights Offering must clear prior to the expiration date of this Rights Offering, and the clearing process may require five or more business days. If you choose to exercise your Subscription Rights, in whole or in part, and to pay for shares and Warrants by personal check and your check has not cleared prior to the expiration date of this Rights Offering, you will not have satisfied the conditions to exercise your Subscription Rights and will not receive the shares and Warrants you wish to purchase.

The receipt of Subscription Rights may be treated as a taxable distribution to you.

We believe the distribution of the Subscription Rights in this Rights Offering should be a non -taxable distribution to holders of shares of common stock and holders of participating warrants under Section 305(a) of the Internal Revenue Code of 1986, as amended, or the Code. Please see the discussion on the “Material U.S. Federal Income Tax Consequences” below. This position is not binding on the IRS, or the courts, however. If this Rights Offering is deemed to be part of a “disproportionate distribution” under Section 305 of the Code, your receipt of Subscription Rights in this offering may be treated as the receipt of a taxable distribution to you equal to the fair market value of the Subscription Rights. Any such distribution would be treated as dividend income to the extent of our current and accumulated earnings and profits, if any, with any excess being treated as a return of

capital to the extent thereof and then as capital gain. Each holder of shares of common stock and each holder of participating warrants is urged to consult his, her or its tax advisor with respect to the particular tax consequences of this Rights Offering.

Exercising the Subscription Rights limits your ability to engage in certain hedging transactions that could provide you with financial benefits.

By exercising the Subscription Rights, you are representing to us that you have not entered into any short sale or similar transaction with respect to our common stock since the Record Date for the Rights Offering. In addition, the Subscription Rights provide that, upon exercise of the Subscription Right, you agree not to enter into any short sale or similar transaction with respect to our common stock for so long as you continue to hold Warrants issued in connection with the exercise of the Subscription Right. These requirements prevent you from pursuing certain investment strategies that could provide you greater financial benefits than you might have realized if the Subscription Rights did not contain these requirements.

The Subscription Rights are not transferable, and there is no market for the Subscription Rights.

You may not sell, transfer, assign or give away your Subscription Rights. Because the Subscription Rights are non -transferable , there is no market or other means for you to directly realize any value associated with the Subscription Rights. You must exercise the Subscription Rights to realize any potential value from your Subscription Rights.

There is no public market for the Preferred Stock in this offering.

There is no established public trading market for the Preferred Stock, and we do not expect a market to develop. In addition, we do not currently intend to apply for listing of the Preferred Stock on any securities exchange or recognized trading system.

Absence of a public trading market for the Warrants may limit your ability to resell the Warrants.

There is no established trading market for the Warrants to be issued pursuant to this offering, we do not currently intend to apply for listing of the Warrants on any securities exchange or recognized trading system, and the Warrants may not be widely distributed. Purchasers of the Warrants may be unable to resell the Warrants or sell them only at an unfavorable price for an extended period of time, if at all.

The market price of our common stock may never exceed the exercise price of the Warrants issued in connection with this offering.

The Warrants being issued in connection with this offering become exercisable upon issuance and will expire five years from the date of issuance. The market price of our common stock may never exceed the exercise price of the Warrants prior to their date of expiration. Any Warrants not exercised by their date of expiration will expire worthless and we will be under no further obligation to the Warrant holder.

The Warrants contain features that may reduce your economic benefit from owning them.

The warrants contain features that allow us to redeem the warrants and that prohibit you from engaging in certain investment strategies. We may redeem the warrants for $0.001 per warrant once the closing price of our common stock has equaled or exceeded $9.30 per share, subject to adjustment, for ten consecutive trading days and on each such day the dollar trading volume exceeds $250,000, provided that we may not do so prior to the first anniversary of expiration of the Rights Offering, and only upon not less than 30 days’ prior written notice of redemption. If we give notice of redemption, you will be forced to sell or exercise your warrants or accept the redemption price. The notice of redemption could come at a time when it is not advisable or possible for you to exercise the warrants. As a result, you may be unable to benefit from owning the warrants being redeemed. In addition, for so long as you continue to hold warrants, you will not be permitted to enter into any short sale or similar transaction with respect to our common stock. This could prevent you from pursuing investment strategies that could provide you greater financial benefits from owning the warrant.

The dealer-managers are not underwriting, nor acting as placement agents of, the Subscription Rights or the securities underlying the Subscription Rights.

Maxim Group LLC and Dawson James Securities, Inc. will act as co -dealer-managers for the Rights Offering. As provided in the dealer -manager agreement, the dealer -managers will provide marketing assistance in connection with this offering. The dealer -managers are not underwriting or placing any of the Subscription Rights or the shares of our Preferred Stock or Warrants being issued in this offering and are not making any recommendation with respect to such Subscription Rights (including with respect to the exercise or expiration of such Subscription Rights), Preferred Stock or Warrants. The dealer -managers will not be subject to any liability to us in rendering the services contemplated by the dealer -manager agreement except for any act of bad faith, gross negligence or willful misconduct by the dealer -managers . The Rights Offering may not be successful despite the services of the dealer -managers to us in this offering.

Since the Warrants are executory contracts, they may have no value in a bankruptcy or reorganization proceeding.

In the event a bankruptcy or reorganization proceeding is commenced by or against us, a bankruptcy court may hold that any unexercised Warrants are executory contracts that are subject to rejection by us with the approval of the bankruptcy court. As a result, holders of the Warrants may, even if we have sufficient funds, not be entitled to receive any consideration for their Warrants or may receive an amount less than they would be entitled to if they had exercised their Warrants prior to the commencement of any such bankruptcy or reorganization proceeding.

All statements, other than statements of historical fact, included regarding our strategy, future operations, financial position, future revenues, projected costs, plans, prospects and objectives are forward -looking statements. Words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “estimate,” “think,” “may,” “could,” “will,” “would,” “should,” “continue,” “potential,” “likely,” “opportunity” and similar expressions or variations of such words are intended to identify forward -looking statements but are not the exclusive means of identifying forward -looking statements. Examples of our forward -looking statements include:

•         our ability to raise funds for general corporate purposes and operations, including our research activities and clinical trials;

•         our ability to recruit qualified management and technical personnel;

•         the success of our clinical trials;

Except as required by applicable law, we do not plan to publicly update or revise any forward -looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise.

This prospectus and the documents incorporated herein by reference also refer to estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry.

In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk.

USE OF PROCEEDS

Assuming that all Units are subscribed for in the Rights Offering, we estimate that the net proceeds from the Rights Offering will be approximately $1.2 million, after deducting expenses relating to this offering payable by us estimated at approximately $0.7 million, including dealer -manager fees and expenses and excluding any proceeds received upon exercise of any Warrants.

We intend to use the net proceeds from the exercise of Subscription Rights for our clinical trials and for general corporate purposes, which may include working capital, capital expenditures, research and development and other commercial expenditures. In addition, we may use the net proceeds from this offering for investments in businesses, products or technologies that are complementary to our business, although we have no present commitments or agreements to make any such investments as of the date of this prospectus. We expect to use any proceeds we receive from the exercise of Warrants for substantially the same purposes and in substantially the same manner. Pending these uses, we intend to invest the funds in short -term , investment grade, interest -bearing securities. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us.

Our management will have broad discretion as to the allocation of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of commencement of this offering.

DILUTION

Purchasers of Units in the Rights Offering will experience an immediate dilution of the net tangible book value per share of our common stock. Our net tangible book value as of March 31, 2019 was approximately $1,244,298, or $0.47 per share of our common stock (based upon 2,620,033 shares of our common stock on an as -exchanged basis with respect to the shares of Exchangeco that can be exchanged for shares of common stock of the Company and taking into account the one -for-ten reverse stock split effective on May 8, 2019). Net tangible book value per share is equal to our total tangible assets less our total liabilities, divided by the number of shares of our outstanding common stock.

Dilution per share of common stock equals the difference between the amount paid by purchasers of Units in the Rights Offering (ascribing no value to the Warrants contained in the Units) and the net tangible book value per share of our common stock immediately after the Rights Offering.

Based on the sale by us in the RD Offering of 1,170,000 shares of common stock and, in a concurrent private placement, warrants to purchase 760,500 shares of common stock, at the combined purchase price of $3.10 per share of common stock and related warrant (assuming no exercise of such warrants), taking into account the one -for-ten reverse stock split of our common stock effective on May 8, 2019, and after deducting estimated offering expenses and placement agent fees and expenses payable by us, our as adjusted net tangible book value as of March 31, 2019 would have been approximately $4.4 million, or $1.17 per share of our common stock.

Based on the sale by us in this Rights Offering of a maximum of 1,860 Units at the Subscription Price of $1,000 per Unit (assuming no exercise of the Warrants), taking into account the one -for-ten reverse stock split of our common stock effective on May 8, 2019, and after deducting estimated offering expenses and dealer -manager fees and expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2019 would have been approximately $5.6 million, or $1.28 per share of our common stock. This represents an immediate increase in the as adjusted net tangible book value to existing stockholders of $0.11 per share of our common stock and an immediate dilution to purchasers in the Rights Offering of $1.82 per share of our common stock. The following table illustrates this per -share of our common stock dilution:

•         120,000 shares of our common stock issuable upon the settlement of outstanding performance stock units, which units were cancelled effective as of April 30, 2019;

•         862,503 shares of our common stock issuable upon the exercise of outstanding warrants, with a weighted -average exercise price of $24.80 per share; and

•         367,317 other shares of our common stock reserved for future issuance under our 2017 Omnibus Equity Incentive Plan, which was decreased to 14,217 effective as of April 30, 2019.

Overview

We are a clinical stage, biopharmaceutical company focused on the development and commercialization of new cancer therapies. Our mission is to benefit patients, by developing and commercializing anti -cancer therapies for patients whose tumors exhibit features that make them resistant to, or unlikely to respond to, currently available therapies, particularly for orphan cancer indications where patients have failed, or are unlikely to respond to, currently available therapy.

We are developing VAL -083 , a novel, validated, DNA -targeting agent, for the treatment of drug -resistant solid tumors such as glioblastoma multiforme (“GBM”) and potentially other solid tumors, including ovarian cancer. VAL -083 is a first -in-class , small -molecule , DNA -targeting chemotherapeutic that demonstrated activity against a range of tumor types in prior Phase 1 and Phase 2 clinical studies sponsored by the US National Cancer Institute (“NCI”). As part of our business strategy, we leverage and build upon these prior NCI investments and data from more than 40 NCI- Phase 1 and Phase 2 clinical studies with our own research to identify and target unmet medical needs in modern cancer care. DNA -targeting agents are among the most successful and widely used treatments for cancer. Their efficacy is based on the ability to bind with a cancer cell’s DNA and interfere with the process of protein production required for growth and survival of cancer cells. “First -in-class ” means that VAL -083 embodies a unique molecular structure which is not an analogue or derivative of any approved product, or product under development, for the treatment of cancer.

Corporate History

We are a Nevada corporation formed on June 24, 2009 under the name Berry Only, Inc. (“Berry’). Prior to a reverse acquisition undertaken on January 25, 2013 Berry did not have any significant assets or operations. We are the parent company of Del Mar Pharmaceuticals (BC) Ltd. (“Del Mar (BC)”), a British Columbia, Canada corporation incorporated on April 6, 2010, that is focused on the development of drugs for the treatment of cancer. We are also the parent company to 0959454 B.C. Ltd., a British Columbia corporation (“Callco”), and 0959456 B.C. Ltd., a British Columbia corporation (“Exchangeco”). Callco and Exchangeco were formed to facilitate the reverse acquisition.

Research and Development

Research and development expenses decreased to $2,702,213 for the nine months ended March 31, 2019 from $5,856,197 for the nine months ended March 31, 2018. The decrease was largely attributable to a decrease in clinical development costs, personnel, preclinical research, intellectual property and travel costs during the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018. For the nine months ended March 31, 2019 and 2018 non -cash , share -based compensation expense of $74,735 and $135,367 respectively, related to stock option expense and shares issued for services. During the nine months ended March 31, 2018, we entered into a separation agreement with our former President and Chief Operating Officer that required the accelerated vesting of certain stock options. The full expense of the accelerated vesting was recognized during the nine months ended March 31, 2018 resulting in a higher non -cash , share -based compensation expense for the nine months ended March 31, 2018 compared to the nine months ended March 31, 2019.

Excluding the impact of non -cash , share -based compensation expense, research and development expenses decreased to $2,627,478 during the current period from $5,720,830 for the prior period. The decrease in clinical development costs for the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 was primarily due to the parking of our STAR -3 , Phase 3 study which was announced in February 2018. During the nine months ended March 31, 2018, we incurred significant study start -up costs. In addition, clinical development costs were higher in the prior period compared to the current period due to the timing of certain manufacturing activities for the production of GMP material and related stability studies. Clinical development costs can vary significantly due to the timing of patient enrollment, how a patient reacts to treatment, and the number of treatment cycles a patient receives.

Personnel costs decreased during the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 primarily due to amounts recognized pursuant to the settlement agreement with our former President and Chief Operating Officer. Preclinical research decreased largely due to a decrease in the ongoing mechanism of action research that we have undertaken in the prior period. Intellectual property costs decreased in the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 as we have refined our patent portfolio by focusing on our most important patent claims in the most important jurisdictions. Patent costs can vary considerably depending on the filing of new patents, conversion of the provisional applications to PCT applications, foreign office actions, and actual filing costs. Travel costs have decreased in the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 as we have focused on reducing all travel expenses.

General and Administrative

General and administrative expenses were $2,796,884 for the nine months ended March 31, 2019 compared to $2,911,538 for the nine months ended March 31, 2018. The decrease was largely due to lower professional fees and travel partially offset by higher personnel and non -cash , share -based compensation expense in the current period compared to the prior period. In relation to general and administrative expenses during the nine months ended March 31, 2019, we incurred non -cash , share -based compensation expense of $510,661 relating to performance

share units, warrants issued for services, and stock option expense while during the nine months ended March 31, 2018, we incurred non -cash , share -based compensation expense of $455,331 relating to warrants issued for services and stock option expense. The performance stock units were issued in April 2018 so no expense for these equity instruments were recognized during the nine months ended March 31, 2018.

Excluding the impact of non -cash , share -based compensation expense, general and administrative expenses decreased in the nine months ended March 31, 2019 to $2,286,223 from $2,456,207 for the nine months ended March 31, 2018. The decrease was primarily due to decreased professional fees and travel costs partially offset by higher personnel costs. Professional fees decreased as a result of certain costs incurred in the prior period that have not been incurred in the current period. Legal fees have decreased in the nine months ended March 31, 2019 compared to nine months ended March 31, 2018 in part due to the timing of our annual meeting of stockholders. In the current period, we have not yet incurred costs for this matter while a portion of these costs was incurred in the prior period. Overall, costs for regulatory filings and corporate governance matters have been lower in the current nine months compared to the prior nine months. Partially offsetting lower legal fees are increased public relations and business development costs due to our efforts to expand our outreach to investors while accounting support has increased due to the complexity of the valuation, and accounting for, our equity instruments. Travel costs have decreased in the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 as we have focused on reducing all travel expenses. Personnel costs have increased during the nine months ended March 31, 2019 compared to the nine months ended March 31, 2018 primarily due to the appointment of our President and Chief Executive Officer in May 2018.

Change in fair value of derivative liability

Based on the terms of certain warrants issued by us, we have determined that the warrants were a derivative liability which is recognized at fair value at the date of the transaction and re -measured at fair value every reporting period with gains or losses on the changes in fair value recorded in the consolidated condensed statement of loss and comprehensive loss. The balances recognized during the nine months ended March 31, 2019 and 2018 were primarily due to changes in our common stock price between the date the warrants were last valued on June 30, 2018 and 2017 respectively. These are the previous valuation dates used for the nine months ended March 31.

We recognized gains of $852 and $57,839 from the change in fair value of the derivative liability for the nine months ended March 31, 2019 and 2018, respectively.

Foreign Exchange

Our functional currency at June 30, 2018 and March 31, 2019 is the US$ but we incur a portion of our expenses in CA$. The foreign exchange gains and losses are reported in other loss (income) in the consolidated condensed interim statement of loss and comprehensive loss. We have recognized foreign exchange losses of $16,754 and $57,406 for the nine -month periods ended March 31, 2019 and 2018, respectively. The losses were due to changes in the exchange rate between the CA$ and the US$ and to varying levels of CA$ cash and accounts payable.

Preferred Share Dividends

For each of the nine -month periods ended March 31, 2019 and 2018 we recorded $6,267 related to the dividend payable to Valent on the Series A preferred stock. The dividend has been recorded as a direct increase in accumulated deficit for both periods.

During the nine months ended March 31, 2019, we issued 14,430 (2018 — 14,881) shares of common stock as a dividend on the Series B Preferred stock and recognized $75,477 (2018 — $142,358) as a direct increase in accumulated deficit.

Research and Development

Research and development expenses increased to $7,132,952 for the year ended June 30, 2018 from $5,003,640 for the year ended June 30, 2017. The increase was largely attributable to an increase in clinical development, personnel, and preclinical research partially offset by lower travel costs. Non -cash , share -based compensation expense for the year ended June 30, 2018 was $149,452 related to stock option expense and shares issued for services while non -cash , share -based compensation expense for the year ended June 30, 2017 was $102,828 for stock option expense and warrants issued for services.

Excluding the impact of non -cash , share -based compensation expense, research and development expenses increased to $6,983,500 during the current year from $4,900,812 for the prior year. The increase in clinical development costs for the year ended June 30, 2018 compared to the year ended June 30, 2017 was partially due to manufacturing costs for GMP material as well as ongoing trial costs for our two Phase 2, biomarker -driven , MGMT -unmethylated , GBM studies. At June 30, 2017, our Phase 2 study in Avastin -naïve unmethylated GBM patients being conducted at the MD Anderson Cancer Center had commenced in February 2017 so patient enrollment had just begun. Also, in the prior year, enrollment in our Phase 2 study in newly diagnosed unmethylated GBM patients in China had not yet started enrollment.

During the year ended June 30, 2018, we undertook site initiation and enrollment for its now -parked STAR -3 , Phase 3 study in GBM. During the year ended June 30, 2018, we recognized certain costs relating to the parking of the trial. As our two Phase 2, biomarker -driven studies are partially supported through collaboration arrangements, the ongoing clinical costs for these two studies will be lower than the overall clinical costs incurred by us for the year ended June 30, 2018.

Personnel costs increased during the current year compared to the prior year primarily due to amounts recognized for payments made to our former President and Chief Operating Officer pursuant to a settlement agreement between us and such individual. Preclinical research increased in the year ended June 30, 2018 compared to the year ended June 30, 2017 largely due our research agreement with Duke University which commenced in April 2017 as well as due to an increase in the ongoing mechanism of action research that we have undertaken in the current year. Travel costs have decreased in the year ended June 30, 2018 compared to the year ended June 30, 2017 as we have focused on reducing all but essential travel.

General and Administrative

General and administrative expenses were $4,041,711 for the year ended June 30, 2018 compared to $3,317,189 for the year ended June 30, 2017. The increase was primarily due to an increase in professional fees and personnel costs. In relation to general and administrative expenses during the year ended June 30, 2018, we incurred non -cash , share -based compensation expense of $596,079 relating to warrants issued for services, stock option expense, and the PSUs while during the year ended June 30, 2017, we incurred non -cash , share -based compensation expense of $667,521 relating to shares and warrants issued for services, and stock option expense.

Excluding the impact of non -cash , share -based compensation expense, general and administrative expenses increased in the year ended June 30, 2018 to $3,445,632 from $2,649,668 for the year ended June 30, 2017. Professional fees incurred during the year ended June 30, 2018 relate to various matters including preparation for

our first annual meeting of stockholders which was held April 11, 2018, completing our 2017 Omnibus Incentive Plan, regulatory filings, and corporate governance matters. In the year ended June 30, 2017, the costs were incurred related to preparing for our uplisting of its common stock on the Nasdaq Stock Market as well as fees associated with one -time listing activities, and the filing of three registration statements with the SEC that were all declared effective in September 2016. Personnel costs increased during the current year compared to the prior year primarily due to amounts recognized for payments made to our former President and Chief Operating Officer pursuant to the settlement agreement.

Change in fair value of stock option and derivative liabilities

Based on the terms of certain warrants issued by us, we determined that such warrants were a derivative liability which is recognized at fair value at the date of the transaction and re -measured at fair value every reporting period with gains or losses on the changes in fair value recorded in the consolidated statement of operations and comprehensive loss. The gains recognized during the years ended June 30, 2018 and 2017 were primarily due to changes in our common stock price between June 30, 2017 and 2016, respectively, and June 30, 2018 and 2017, respectively.

We recognized a gain of $60,111 from the change in fair value of the derivative liability for the year ended June 30, 2018 and a gain of $331,057 for the year ended June 30, 2017.

Changes in our common stock price can result in significant volatility in our reported net loss due to its impact on the fair value of the derivative liability. As a result of revaluation gains and losses, we expect that our reported net income or loss will continue to fluctuate significantly.

Certain of our stock options have been issued in $CA. Of these, a portion were classified as a stock option liability which is revalued at each reporting date. During the year ended June 30, 2017, we amended 4,375 of these stock options held by five optionees such that the exercise price of the options was adjusted to be denominated in $USD. No other terms of the stock options were amended. As a result of the amendment, we recognized $85,094 in stock option liability expense and $260,969 was reclassified to equity during the year ended June 30, 2017.

Foreign Exchange

Our functional currency at June 30, 2018 was the US$, but we incur a portion of its expenses in CA$. The foreign exchange gains and losses are reported in other loss (income) in the consolidated statement of operations and comprehensive loss.

We recognized foreign exchange losses of $57,003 and $7,355 for the years ended June 30, 2018 and 2017, respectively. The losses were due to changes in the exchange rate between the CA$ and the US$ and to varying levels of CA$ cash and accounts payable.

Preferred Share Dividends

For each of the years ended June 30, 2018 and 2017, we recognized $8,356 related to the dividend payable to Valent on the Series A preferred stock. The dividend has been recorded as a direct increase in accumulated deficit for both periods.

We issued 19,841 (2017 — 20,045) shares of common stock on June 30, 2018 as a dividend on the Series B Preferred stock and recognized $176,236 (2017 — $790,454) as a direct increase in accumulated deficit.

During the nine months ended March 31, 2019, we recorded a gain from the revaluation of the derivative liability of $852 compared to a gain of $57,839 for the nine months ended March 31, 2018. Excluding the impact of changes in the fair value of the derivative liability, non -cash items relating to amortization of intangible assets, shares and warrants issued for services, stock option expense, and performance share unit expense totaled $598,944 for the nine months ended March 31, 2019. Non -cash items relating to amortization of intangible assets, warrants issued for services, and stock option expense totaled $608,567 for the nine months ended March 31, 2018.

The most significant changes in non -cash working capital for the nine months ended March 31, 2019 was an increase in cash from a decrease in prepaid expenses and deposits of $794,859 due to a partial refund of our clinical trial deposit related to our now -parked STAR -3 Phase 3 study. The other significant change in on -cash working capital in the current period was a decrease in cash from a reduction in accounts payable and accrued liabilities of $425,383. The most significant changes in non -cash working capital for the nine months ended March 31, 2018 was cash from an increase of accounts payable and accrued liabilities of $708,634 and cash from a decrease in prepaid expense and deposits of $135,293.

During the year ended June 30, 2018, we received $8,945,336 in net proceeds from the completion of a registered direct offering by us of common stock and common stock purchase warrants. During the year ended June 30, 2017, we received $7,932,107 in net proceeds from a public offering of its common stock and common stock purchase warrants.

During the years ended June 30, 2018 and 2017, we received $312,500 and $545,026, respectively, from the exercise of warrants. In addition, we recognized $8,356 related to the dividend payable to Valent during each of the years ended June 30, 2018 and 2017, respectively.

Going Concern and Capital Expenditure Requirements

June 2019 Offering

On June 5, 2019, we completed a registered direct offering (the “RD Offering”) of an aggregate of 1,170,000 shares of common stock and, in a concurrent private placement, warrants to purchase 760,500 shares of common stock at a combined purchase price of $3.10 per share and related warrant. The warrants have an exercise price of $3.10 per share, are immediately exercisable and have a term of exercise of five years. The gross proceeds from the offering, prior to deducting offering expenses and placement agent fees and expenses payable by us, were $3.6 million.

Going Concern

(See note 1 to the consolidated condensed interim financial statements)

The consolidated condensed interim financial statements have been prepared on a going concern basis which assumes that we will continue our operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business.

For the nine months ended March 31, 2019, we reported a loss of $5,465,486 and negative cash flow from operations of $4,514,674. As of March 31, 2019, we had an accumulated deficit of $57,988,567 and cash and cash equivalents on hand of $2,152,233. We are in the development stage and have not generated any revenues to date. We do not have the prospect of achieving revenues until such time that our product candidate is commercialized, or partnered, which may not ever occur. In the near future, we will require additional funding to maintain our clinical trials, research and development projects, and for general operations. These circumstances indicate substantial doubt exists about our ability to continue as a going concern.

Consequently, management is pursuing various financing alternatives to fund our operations so we can continue as a going concern, including the proposed rights offering recently announced by us. Management plans to secure the necessary financing through the issue of new equity and/or the entering into of strategic partnership arrangements. We may tailor our drug candidate development program based on the amount of funding we are able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.

The financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. Such adjustments could be material.

Our future funding requirements will depend on many factors, including but not limited to:

•         the rate of progress and cost of our clinical trials, preclinical studies and other discovery and research and development activities;

•         the costs associated with establishing manufacturing and commercialization capabilities;

Additionally, the study protocol has been amended to include enrollment of up to 24 newly -diagnosed GBM patients who have completed chemoradiation treatment with TMZ and received no subsequent TMZ maintenance therapy but will receive VAL -083 instead (Group 2). This Group has been included to explore whether earlier intervention with VAL -083 instead of TMZ maintenance therapy offers clinical benefit and extends the time to recurrence as compared to TMZ maintenance therapy.

Consistent with prior studies, myelosuppression (primarily thrombocytopenia and neutropenia) is the most common adverse event in both ongoing clinical trials.

VAL-083 Clinical Studies

We are currently developing VAL -083 , a novel DNA -targeting agent for the treatment of GBM and potentially other solid tumors, including ovarian cancer. Our recent research has highlighted the opportunities afforded by VAL -083 ’s unique mechanism of action and its potential to address unmet medical needs by focusing our development efforts on patients whose tumors exhibit biological features that make them resistant to, or unlikely to respond to, currently available therapies. For example, our research demonstrating VAL -083 ’s activity in GBM is independent of the MGMT methylation status allows us to focus patient selection based on this important biomarker.

The evaluation of MGMT promotor methylation status has increasingly become common practice in the diagnostic assessment of GBM. In September 2017, the National Comprehensive Cancer Network (“NCCN”) updated guidelines for the standard treatment of GBM based on MGMT methylation status. We believe these recently published guidelines provide for enhanced opportunities for us to capitalize on VAL -083 ’s unique mechanism of action by utilizing MGMT methylation as a biomarker to optimize patient selection for our novel DNA -targeting agent to target the majority of GBM patients who are diagnosed with MGMT -unmethylated tumors.

Our current priority is to leverage this research and VAL -083 ’s unique mechanism of action to efficiently advance our drug candidate for the most promising indications, including:

•         MGMT -unmethylated GBM, currently comprising two ongoing separate Phase 2 clinical studies for:

•         rGBM patients (ongoing study at MDACC); and

•         Newly diagnosed GBM patients (ongoing study at Sun Yat -sen University); and

•         Based on published data from our Phase 2 studies being conducted at MDACC and in China, we have identified an additional opportunity in pre -temozolomide maintenance GBM patients, and

•         Potential future indications include ovarian cancer, non -small cell lung cancer (“NSCLC”), and other solid tumor indications.

MGMT-unmethylated GBM

GBM is the most common and the most lethal form of glioma. According to the Central Brain Tumor Registry of the United States, GBM occurs with an incidence of 3.20 per 100,000 person -years . Approximately 13,000 new cases of GBM were diagnosed in the United States and 16,000 in Europe during 2017. Within the GBM patient population, approximately two -thirds of patients are unmethylated with respect to their MGMT status.

Measurement of MGMT (O6 -methyl guanine methyltransferase) methylation status has become routine in clinical practice as a biomarker that correlates with resistance to the standard -of-care chemotherapy with temozolomide (Temodar ® “TMZ”), and patient outcomes in GBM. Greater than 60% of GBM patients’ tumors are characterized as “MGMT -unmethylated ” and exhibit a high expression of MGMT, a naturally occurring DNA -repair enzyme, the activity of which nullifies the chemotherapeutic activity of TMZ. The development of new therapies for MGMT -unmethylated GBM is a significant unmet medical need. Importantly, the most recent update to NCCN guidelines states that the treatment benefit of TMZ is likely to be lower in GBM patients with an unmethylated MGMT promoter, and therefore, allows for withholding of TMZ in the treatment of newly diagnosed GBM patients with MGMT -unmethylated tumors due to lack of efficacy.

We have demonstrated that VAL -083 ’s anti -tumor mechanism is active independent from the MGMT status in vitro . We believe this suggests the potential of VAL -083 as a replacement for the current standard -of-care chemotherapy, temozolomide, in MGMT -unmethylated GBM. We are therefore utilizing MGMT -methylation status to identify GBM patients who are unlikely to respond to temozolomide and instead treat them with VAL -083 .

We believe that our research, in the context of the recent amendment to NCCN guidelines, highlights this unmet need and the opportunity for VAL -083 as a potential new standard -of-care in the treatment of MGMT -unmethylated GBM.

Phase 2 Study in MGMT-unmethylated rGBM in Collaboration with University of Texas MD Anderson Cancer Center

In February 2017, we initiated a biomarker driven, open -label , single -arm Phase 2 study in collaboration with MDACC. This study will enroll up to 48 MGMT -unmethylated GBM patients whose tumors have recurred following treatment with temozolomide. These patients will not have been treated previously with Avastin ® . The primary endpoint of the study is overall survival. The historical comparison survival data for this study is lomustine based on a median overall survival of 7.2 months in unmethylated patients. Safety data from this study will become part of the overall safety dossier to support future filings with the FDA and other regulatory agencies.

As of March 13, 2019, 47 patients had been enrolled in this Phase 2 study. The original starting dose of 40 mg/m 2 of VAL -083 on days 1, 2 and 3, of a 21 -day cycle, which was based on the results from our previous Phase 1/2 safety study of VAL -083 in patients with recurrent glioma (clinicaltrials.gov identifier: NCT01478178), has continued to demonstrate myelosuppression as the principal side effect of VAL -083 , as per prior clinical experience. The safety profile has been well within the existing safety monitoring guidelines described in the present study protocol. However, in consultation with the principal investigator at MDACC, we have amended the protocol for this clinical study to modify the starting dose of VAL -083 to 30 mg/m 2 on days 1, 2 and 3, of a 21 -day cycle for this specific population previously treated with temozolomide. This modification may improve tolerance in this patient population and maximize overall exposure to VAL -083 thereby increasing the number of cycles of drug patients are able to receive. We have modified the patient screening platelet count, from 100,000/µL to 125,000/µL, for the same reasons.

At the AACR’s annual meeting in April 2019, we reported that per investigator assessment at the end of cycle 2:

•         9/35 (25.7%) patients initially receiving 40 mg/m2 exhibited Stable Disease

•         4/10 (40.0%) patients initially receiving 30 mg/m2 exhibited Stable Disease

•         Two patients have not yet reached the end of cycle 2

On April 3, 2019, we announced that MDACC approved the adding of up to 35 patients to the recurrent GBM study at a dose of 30 mg/m 2 . We had previously lowered the dose in this study from 40 mg/m 2 to 30 mg/m 2 to improve tolerance in this patient population and maximize overall exposure to VAL -083 thereby increasing the number of cycles of drug patients are able to receive. Upon completion of original 48 patients in this study, 13 will have had the 30 mg/m 2 dose and 35 will have had the 40 mg/m 2 . Therefore, potentially adding an additional 35 patients at 30 mg/m 2 would result in a total of 48 patients receiving the 30 mg/m 2 dose. We are still determining how many, if any, additional patients will be added at the 30 mg/m 2 dose.

It is important for this GBM patient population, which has been heavily pre -treated with temozolomide, to be able to be treated with multiple cycles of VAL -083 without significant hematological toxicities. We believe the modified dose of VAL -083 , in addition to the change in patient eligibility platelet counts, should help provide for enhanced patient safety. We believe a positive outcome from this study can establish a position for VAL -083 in the treatment of MGMT -unmethylated rGBM.

Based on current enrollment rates, we are forecasting full enrollment in the second calendar quarter of 2019. Data from this study will be used to help develop potential future clinical study designs with VAL -083 in MGMT -unmethylated rGBM. A detailed description of this study can be found at clinicatrials.gov, Identifier Number: NCT02717962.

As noted above, patients in our current MDACC clinical study have been heavily pre -treated with temozolomide. Based on published data from our MDACC and SYSUCC clinical studies, we believe there is a significant opportunity to treat GBM patients in the pre -temozolomide maintenance stage. At the AACR’s annual meeting in April 2019, we reported that myelosuppression (thrombocytopenia and neutropenia) is the most common adverse event associated with VAL -083 . The higher potential for myelosuppression with the 40 mg/m 2 /day of VAL -083 in this study appears to be correlated with the number of cycles of prior TMZ maintenance therapy (> 5 cycles). These patients will have had an initial cycle of temozolomide following radiation but will not have yet started subsequent cycles of temozolomide (i.e. maintenance stage TMZ patients). The MDACC IRB has approved the addition of up

to 24 patients to the pre -TMZ maintenance setting. These patients will have had an initial cycle of temozolomide following radiation but will not have yet started subsequent cycles of temozolomide (i.e. maintenance stage TMZ patients). Subject to obtaining financing and all regulatory approvals, we are planning a new Phase 2 study that would potentially enroll up to 24 pre -TMZ maintenance stage, MGMT -unmethylated GBM patients. The comparison survival data for this study is survival data from Tanguturi et al (2017 Nero -Oncology ) for MGMT -unmethylated patients of 6.9 months.

Phase 2 Study in Newly Diagnosed MGMT-unmethylated GBM

In September 2017, we initiated a single arm, biomarker driven, open -label Phase 2 study in newly diagnosed MGMT -unmethylated GBM patients at Sun Yat -sen University Cancer Center (SYSUCC) in Guangzhou, China. The study is being conducted under our collaboration agreement with Guangxi Wuzhou Pharmaceutical Company.

In this Phase 2 study, VAL -083 is being combined with radiotherapy as a potential replacement for standard -of-care chemoradiation with temozolomide in patients with MGMT -unmethylated GBM. One goal of the study will be to confirm the safety of the three -day VAL -083 dosing regimen in combination with radiotherapy and to investigate outcomes of the combination of VAL -083 and radiotherapy in MGMT -unmethylated GBM patients.

We plan to enroll up to 30 newly -diagnosed , MGMT -unmethylated GBM patients in this study. The efficacy endpoints of the study include tumor response, as assessed by the Response Assessment in NeuroOncology (“RANO”), and progression -free survival (“PFS”), progression -free survival at six months (“PFS6”), and overall survival (“OS”), compared to historical results in the target population. The study is being conducted in two parts: (1) Dose -confirmation : VAL -083 in cohorts (20, 30 and 40 mg/m2/day IV daily x 3 every 21 days) to assess safety and activity when administered concurrently with x -ray therapy (“XRT”) to confirm the maximum tolerated dose (“MTD”), and (2) Expansion: VAL -083 will be studied in up to 20 additional patients at the target dose, as determined by the dose -confirmation part of the study, administered concurrently with XRT. Assessments of safety and tolerability will be used to support further clinical development of VAL -083 in combination with radiotherapy. Pharmacokinetic assessments of VAL -083 in plasma and cerebral spinal fluid (“CSF”) will be used to correlate drug exposure in the central nervous system with patient outcomes.

Dose confirming cohorts studying 20, 30, and 40 mg/m 2 /day x three every 21 days have been completed. Based on the dose confirmation phase of the study, we have selected 30 mg/m 2 for combination with irradiation for the treatment of newly -diagnosed MGMT -unmethylated GBM patients.

As of February 15, 2019, 15 patients have been enrolled in this study. The Company is pleased to report that for the 15 patients enrolled to February 15, 2019, 11 have completed their prospectively planned Magnetic Resonance Imaging (MRI) scans and have had their initial assessment for tumor progression. Tumor progression is based on the study investigator’s clinical and radiologic assessment, according to the RANO criteria. Of these 11 patients, five were assessed by the Principal Investigator as having a “Complete Response”, three of whom were based on significant tumor shrinkage, and two of whom were based on their tumors continuing to remain “below measurable level” from post -surgery baseline MRI to post -cycle 3 MRI. Additionally, six patients were assessed as having “Stable Disease.” Of the remaining four patients, one died prior to their post -cycle 3 MRI and three have not been on study long enough to reach their planned post -cycle 3 MRI. As of the February 15, 2019 data cutoff, 12 of the 15 enrolled patients are still alive. Similar to prior experience, myelosuppression has been the most common adverse event observed. Two dose -limiting toxicities have been reported (thrombocytopenia) — one at the 40 mg/m 2 /day dose and one at the 30 mg/m 2 /day dose.

Through our research, and that of the NCI, we have previously demonstrated that VAL -083 crosses the blood brain barrier. New preliminary data from the SYSUCC study indicate that the concentration of VAL -083 is generally higher in CSF than in plasma at two hours post -infusion .

Concentration of VAL-083 — Two Hours Post Dose

By comparison, temozolomide is typically 80% lower in the CSF than the plasma (Schreck et al. 2018, Oncology (Williston Park)). The reason this is important is that accumulation of VAL -083 in the CSF further validates that VAL -083 crosses the blood -brain-barrier and demonstrates that therapeutic drug concentrations in the CSF are achievable for extended periods of time.

Ovarian Cancer

In April 2016, the FDA granted orphan drug designation for the use of VAL -083 in the treatment of ovarian cancer.

In September 2017, we filed an IND for the use of VAL -083 in ovarian cancer, along with a protocol for a Phase 1/2, open -label , multicenter, study of VAL -083 in patients with Re current P latinum R esistant Ov arian Cancer (the REPROVe study).

The FDA has allowed this study to begin enrolling patients, but based on ongoing evaluation and input from our ovarian advisory board, we are reassessing the ovarian cancer program. We are in the process of evaluating the best path forward in ovarian cancer and are looking at various strategic options including combination with PARP inhibitors.

Fast Track Designation

In December 2017, the FDA granted Fast Track designation for VAL -083 in rGBM.

Fast Track designation is designed to expedite the review of drugs that show promise in treating life -threatening diseases and address unmet medical needs, with the goal of getting new treatments to patients earlier. Fast Track designation provides sponsors with an opportunity for increased frequency for communication with the FDA to ensure an optimal development plan and to collect appropriate data needed to support drug approval. Additional benefits of the Fast Track designation may include an Accelerated Approval, a Priority Review, and a Rolling Review. Accelerated Approval is granted to drugs that demonstrate an effect on a surrogate, or intermediate endpoints, reasonably likely to predict clinical benefit. Priority Review shortens the FDA review process for a new drug from ten months to six months and is appropriate for drugs that demonstrate significant improvements in both safety and efficacy of an existing therapy. Rolling Review provides a drug company the opportunity to submit completed sections of its New Drug Application (“NDA”) for review by the FDA. Typically, NDA reviews do not commence until the drug company has submitted the entire application to the FDA. Through the Fast Track designation, the FDA attempts to ensure that questions raised during the drug development process are resolved quickly, often leading to earlier approval and increased access for patients.

Current Treatments for Gliomas and Glioblastoma Multiforme

Gliomas are a type of Central Nervous System (“CNS”) tumor that arises from glial cells in the brain or spine. Glial cells are the cells surrounding nerves. Their primary function is to provide support and protection for neurons in the CNS.

GBM is the most common and the most lethal form of glioma. According to the Central Brain Tumor Registry of The United States, GBM occurs with an incidence of 3.20 per 100,000 person -years . Approximately 13,000 new cases of GBM were diagnosed in the United States and 16,000 in Europe during 2017.

Common symptoms of GBM include headaches, seizures, nausea, weakness, paralysis and personality or cognitive changes such as loss of speech or difficulty in thinking clearly. GBM progresses quickly and patients’ conditions

deteriorate rapidly progressing to death. The outlook for GBM patients is generally poor. The overall median survival in newly diagnosed GBM patients with best available treatments is less than 15 months, and two -year and five -year survival rates are approximately 30% and 10%, respectively. Median overall survival in newly -diagnosed , unmethylated GBM patients is 12.2 months.

In September 2017, the National Comprehensive Cancer Network (“NCCN”), updated treatment guidelines for GBM. The recommended treatment regimen for GBM includes surgical resection to remove as much of the tumor as possible (“debulking”) followed by radiotherapy with concomitant and adjuvant chemotherapy with temozolomide with or without tumor treating fields (“TTF”). GBM patients whose tumors exhibit an unmethylated promotor for the gene encoding the DNA repair enzyme MGMT, a biomarker correlated with resistance to temozolomide, may be treated with radiation alone following surgery.

Patients with an unmethylated MGMT promotor have high levels of MGMT, a naturally -occurring DNA repair enzyme that repairs tumor -fighting lesions induced by TMZ thus allowing a patient’s tumor to continue to grow despite treatment which leads to poor outcomes. Measurement of MGMT methylation status has become routine in clinical practice as biomarker that correlates with response to TMZ and patient outcomes in GBM.

Probability of GBM Patient Survival Correlated to Expression of MGMT Enzyme
(Unmethylated promoter = High MGMT Expression and Significantly Shorter Survival)

TTF (Optune ® ) is a non -invasive technique for adults with GBM. TTF uses alternating electrical fields to disrupt tumor cell division, or cause cell death, thereby preventing the tumor from growing or spreading as quickly. A clinical study reported that GBM patients treated with TTF combined with TMZ experienced longer survival than those treated with TMZ alone.

The majority of GBM patients’ tumors recur within 6 – 12 months of initial treatment. Experimental therapy through clinical studies is recommended under NCCN guidelines for eligible patients. NCCN guidelines also recommend treatment with systemic chemotherapy, such as lomustine (“CCNU”). For patients who are eligible for additional surgical debulking, local chemotherapy with carmustine (“BCNU”) wafers may be employed. CCNU and BCNU target the same DNA -site as TMZ and are also subject to MGMT -related resistance.

Avastin (Avastin ® , an anti -VEGF antibody) recently received full approval in the US, Canada, Australia, and Japan as a single agent for patients with recurrent GBM following prior therapy. Avastin carries an FDA “black -box warning” related to severe, sometimes fatal, side effects such as gastrointestinal perforations, wound healing complications and hemorrhage. There are no data demonstrating an improvement in disease -related symptoms or increased survival for GBM patients treated with Avastin.

Recurrent GBM patients, especially those whose tumors progress following treatment with Avastin, have limited or no treatment options and a very poor prognosis. According to published literature, the median survival for GBM patients whose tumors progress following Avastin is less than five months.

VAL-083 Mechanism of Action and the Opportunity in the Treatment of Cancer

Chemotherapy forms the basis of treatment in nearly all cancers. We believe that VAL -083 may be effective in treating tumors exhibiting biological features that cause resistance to currently available chemotherapy, particularly for patients who have failed, or become resistant to, other treatment regimens.

Based on published research and our own data, the cytotoxic functional groups, and the mechanism of action of VAL -083 are functionally different from alkylating agents commonly used in the treatment of cancer. VAL -083 has previously demonstrated activity in cell -lines that are resistant to other types of chemotherapy. No evidence of cross -resistance has been reported in published clinical studies.

Our research suggests that VAL -083 attacks cancer cells via a unique mechanism of action which is distinct from other chemotherapies used in the treatment of cancer. Our data indicate that VAL -083 forms inter -strand crosslinks at the N 7 position of guanine on the DNA of cancer cells. Our data also indicate that this crosslink forms rapidly and is not easily repaired by the cancer cell resulting in cell -cycle arrest and lethal double -strand DNA breaks in cancer cells. VAL -083 readily crosses the blood brain barrier. Published preclinical and clinical research demonstrate that VAL -083 is absorbed more readily in tumor cells than in normal cells.

In vitro , our data also demonstrate that VAL -083 ’s distinct mechanism may be able to overcome drug resistance against a range of cancers. For example, VAL -083 is active against MGMT -unmethylated GBM cells which are resistant to treatment with temozolomide and nitrosoureas. VAL -083 also retains a high level of activity in p53 mutated non -small cell lung cancer (“NSCLC”), ovarian cancer and medulloblastoma cell lines that are resistant to platinum -based chemotherapy.

Importantly, clinical activity against each of the tumors mentioned above was established in prior NCI -sponsored Phase 2 clinical studies. We believe that these historical clinical data and our own research support the development of VAL -083 as a potential new treatment for multiple types of cancer.

The main dose -limiting toxicity (“DLT”) related to the administration of VAL -083 in previous NCI -sponsored clinical studies and our own clinical studies is myelosuppression, particularly thrombocytopenia. Myelosuppression, including thrombocytopenia, is a common side effect of chemotherapy. Myelosuppression is the decrease in cells responsible for providing immunity, carrying oxygen, and causing normal blood clotting. Thrombocytopenia is a reduction in platelet counts which assist in blood clotting. Modern medicine allows for better management of myelosuppressive side effects. We believe this offers the potential opportunity to improve upon the drug’s already established efficacy profile by substantially increasing the dose of VAL -083 that can be safely administered to cancer patients.

There is no evidence of lung, liver, or kidney toxicity even with prolonged treatment by VAL -083 . Data from the Chinese market where the drug has been approved for more than 15 years supports the safety findings of the NCI studies.

VAL-083 Historical Data

VAL -083 is first -in-class DNA targeting agent that readily crosses the blood -brain-barrier . Data from prior NCI -sponsored clinical studies with VAL -083 demonstrate activity against GBM and other CNS tumors. In general, historical NCI -sponsored studies demonstrate that tumor regression in brain cancer was achieved in 40% of patients treated and stabilization was achieved in an additional 20% to 30% of brain tumor patients following treatment with VAL -083 . In these studies, VAL -083 demonstrated statistically significant improvement in the median survival of high -grade glioma brain tumors, including GBM when combined with radiation versus radiation alone (p < 0.05) with results similar, or superior to, other chemotherapies approved for the treatment of GBM.

A Summary of Published Data adapted from Separate Sources Comparing the Efficacy of VAL -083
and Other Therapies in the Treatment of GBM

VAL-083 is Active Independent of MGMT

We have presented data at several peer reviewed meetings demonstrating that VAL -083 is active independent of MGMT resistance in GBM cell lines and other CNS tumor cells. Our research, along with that of others, demonstrates that VAL -083 ’s unique cytotoxic mechanism forms DNA cross -links at the N 7 position of guanine and retains cytotoxic activity independent of MGMT expression in vitro . Our studies demonstrate that VAL -083 has more potent activity against brain tumor cells in comparison to TMZ and overcomes resistance associated with MGMT, suggesting the potential to surpass the current standard -of-care in the treatment of GBM.

A Summary of Our Data Demonstrating that VAL -083 ’s Anti -Tumor Mechanism is
Distinct from, and can Overcome, MGMT -Related Chemo resistance in the Treatment of GBM

In addition, historical NCI clinical study data and our own research support the activity of VAL -083 as a potentiator of radiotherapy. Radiotherapy in combination with temozolomide is the current standard of care in the treatment of newly diagnosed GBM. Our research demonstrates that temozolomide and radiotherapy are ineffective against GBM cells exhibiting a high expression of MGMT, whereas VAL -083 potentiates the tumor -killing effect of radiation independent of MGMT expression. Furthermore, the combination of VAL -083 and radiation has been demonstrated to be active against GBM cancer stem cells (“CSCs”) in vitro. CSCs are often resistant to chemotherapy and form the basis for tumor recurrence and metastasis. GBM CSCs display strong resistance to TMZ, even where MGMT expression is low. However, our data demonstrates that GBM CSCs are susceptible to VAL -083 independent of MGMT expression.

A Summary of Our Data Demonstrating that VAL -083 Maintains Activity in Both Temozolomide -resistant GBM Cell Lines and Matched Cancer Stem Cells and Potentiates Radiotherapy

We believe that VAL -083 ’s more potent activity against brain tumor cells in comparison to TMZ, VAL -083 ’s ability to overcome MGMT -mediated resistance, and its activity against GBM CSCs suggests the potential of VAL -083 to surpass the current standard -of-care in the treatment of GBM.

Phase 1 – 2 Clinical Study Overview and Summary of Results

In an open -label , single arm dose -escalation study designed to evaluate the safety, tolerability, pharmacokinetics, and anti -cancer activity of VAL -083 , we enrolled forty -eight GBM patients whose disease progressed following prior treatment with temozolomide and Avastin. The study was conducted at five centers in the United States: the Mayo Clinic in Rochester, Minnesota; the Brain Tumor Center at University of California, San Francisco; the Sarah Cannon Cancer Research Center in Nashville, Tennessee and Denver, Colorado; and the SCRI affiliate site at the Florida Cancer Specialist Research Institute in Sarasota, Florida.

Patients received VAL -083 on days 1, 2 and 3 on a 21 -day treatment cycle. The Phase 1 portion of the study involved dose escalation cohorts until a maximum tolerated dose (“MTD”) was established at 40mg/m 2 . A further 14 -patient , Phase 2 expansion was then enrolled at the MTD to gather further safety data at our chosen therapeutic dose and to further explore the outcomes in this patient population.

In May 2016, we held an end of Phase 2 meeting with the FDA in which we discussed with the FDA the design of a Phase 3, registration -directed clinical program for VAL -083 in refractory GBM. Based on the input we received from the FDA, the agency confirmed that it would consider the totality of data available, including data obtained from our other planned clinical studies in related GBM populations, when assessing the NDA. The FDA also noted that we may be able to rely on prior NCI studies and historical literature to support nonclinical data required for an NDA filing under a 505(b)(2) strategy which allows a sponsor to rely on already established safety and efficacy data in support of an NDA.

In summary, the data from our previous Phase 1/2 study are as follows:

Safety and Tolerability

In the Phase 1 dose escalation regimen, no serious adverse events (“SAE”) related to VAL -083 were encountered at doses up to 40 mg/m 2 /day.

Increasing frequency of, and higher grade, hematologic toxicities were observed at doses above 40 mg/m 2 /day. Consistent with the published literature, the observed dose limiting toxicity for VAL -083 is primarily thrombocytopenia (low platelets). Observed platelet nadir occurred at approximately day 18, and recovery was rapid and spontaneous following treatment.

Based on Phase 1 observations, fourteen additional patients were enrolled in a Phase 2 expansion cohort at 40mg/m 2 , which was established as the MTD. Consistent with Phase 1, the dose of VAL -083 of 40 mg/m 2 on days 1, 2 and 3 of a 21 -day cycle was generally well tolerated in Phase 2. At this dose, one subject previously treated with CCNU, a

nitrosourea agent, reported severe (Grade 4) thrombocytopenia. As a result of this observation, the protocol inclusion criterion for platelet count was increased from 100,000/μL to 150,000/μL for patients receiving prior nitrosoureas within 12 weeks preceding enrollment. No other dose limiting toxicities were observed.

Daily x 5 q 5wks refers to a dosing regimen of once per day for five consecutive days every five weeks (35 -day cycle); while daily x 3 q 3wks refers to a dosing regimen of once per day for three consecutive days every three weeks (21 -day cycle).

Our achieved dosing regimen increased the amount of VAL -083 delivered to the CNS over historical regimens without increased toxicity. Thus, our regimen achieved both a higher maximum concentration and higher overall exposure, which we believe may increase the likelihood of successful treatment outcomes in glioblastoma and other brain tumors.

Based on our ongoing Phase 2 study at MDACC, we believe that the safety profile of the 40 mg/m 2 is within the existing safety monitoring guidelines described in the present study protocol. However, in consultation with the principal investigator at MDACC, we have amended the protocol for the study to modify the starting dose of VAL -083 to 30 mg/m 2 on days 1, 2 and 3, of a 21 -day cycle for this specific study population which has been previously treated with temozolomide. We believe this modification may improve tolerance in this patient population and maximize overall exposure to VAL -083 thereby increasing the number of cycles of drug patients are able to receive. The 30 mg/m 2 dosing regimen is 20% over the historical regimen.

Pharmacokinetics

Pharmacokinetic (“PK”) analyses showed dose -dependent linear systemic exposure with a short (1 -2h ) plasma terminal half -life ; average Cmax at 40 mg/m 2 /day was 781 ng/mL (5.3µM). The observed PK profile is comparable to published literature. Prior NCI -sponsored studies demonstrated that VAL -083 readily crosses the blood brain barrier and has a long (>20 hour) half -life in the CNS.

We believe that this PK profile is optimal for the treatment of brain tumors: A long CNS half -life is expected to maximize exposure of the drug in the brain increasing the likelihood of successful treatment outcomes, while a short plasma half -life is desirable to minimize systemic side effects.

Observed pharmacokinetics from VAL-083 Phase 1 clinical study dose vs. AUC

Based on observed and previously published pharmacokinetics, we believe that therapeutic doses equal to, or above, 20 mg/m 2 daily on days 1, 2 and 3 of a 21 -day cycle should deliver sufficient levels of VAL -083 to brain tumors to achieve a therapeutic benefit. We are currently using a dose of 30 mg/m 2 daily on days 1, 2 and 3 of a 21 -day cycle in our two Phase 2 studies that are currently ongoing.

MGMT & IDH1

High expression of MGMT and wild -type form of the enzyme isocitrate dehydrogenase (“IDH1”) have been previously shown to be diagnostic markers that correlate with resistance to currently available chemotherapies (e.g. temozolomide or nitrosourea) in the treatment of GBM and poor patient outcomes. Measurement of these biomarkers has become routine in clinical practice.

Notably, we have previously demonstrated that VAL -083 ’s anti -tumor mechanism is active independent from the MGMT status in vitro . We believe we will ultimately be able to use such biomarkers in a prognostic fashion to select the patients most likely to respond to treatment as we expand the clinical development of VAL -083 .

Tumor Response and Outcomes

GBM patients in our Phase 1/2 clinical study were not re -resected prior to treatment with VAL -083 and therefore had a growing recurrent GBM tumor at the time of enrollment. Patients were monitored for tumor response by MRI.

Consistent with un -resected GBM, median progression free survival (“PFS”) was short at 1.2 months (range: 0.2 – 20.1 months). Five GBM patients treated with VAL -083 were reported to have stable disease as their best response following treatment; the remainder reported progressive disease.

Disease progression is typical in a refractory GBM population with non -resected tumors. However, we believe that slowed progression may provide meaningful clinical benefit in this patient population through prolonged overall survival and improved quality of life.

According to published literature, GBM patients failing Avastin have a poor prognosis with expected survival under five months.

Analysis of twenty -two patients receiving an assumed therapeutic dose of VAL -083 (≥20mg/m 2 ) demonstrated median survival of 8.35 months following Avastin failure.

VAL-083 compared to published literature

While recognizing these data are representative of a relatively small, non -controlled Phase 1/2 clinical study, we believe these outcomes support the potential of VAL -083 to offer meaningful clinical benefit to GBM patients who have failed Avastin, compared to currently available therapy.

VAL-083 Historical Data and Our Research in Ovarian Cancer

Ovarian cancer is the fifth most common cancer in women and is the leading cause of death among women diagnosed with gynecological malignancies. In 2016, approximately 22,300 women in the US were diagnosed with ovarian cancer and 14,300 died from their disease.

Without treatment, ovarian cancer spreads within the pelvic region and metastasizes to distant sites such as the lungs, liver, spleen and, rarely, the brain. The initial symptoms of ovarian cancer such as abdominal bloating, indigestion, pelvic pain, or nausea are often attributed to symptoms caused by a less serious condition. Therefore, in most cases, ovarian cancer is not diagnosed until it has progressed to an advanced stage when it is no longer possible to surgically remove all tumor tissue.

When diagnosed at an advanced stage the 5 -year survival rate is less than 40%. Women with ovarian cancer receive chemotherapy following surgery to treat residual disease.

VAL -083 ’s activity against ovarian epithelial adenocarcinoma (“OEA”) and squamous cell carcinoma of the cervix (“SCC”) was reported in prior NCI -sponsored clinical studies. Importantly, NCI -researchers recommended VAL -083 for further advanced studies in the treatment of ovarian cancer.

Pt -based chemotherapy is employed in the treatment of nearly 50% of all cancer patients and is employed in the treatment regimen of nearly all advanced -stage ovarian cancer patients. Ovarian cancer patients whose tumors are sensitive to Pt -based chemotherapy have the most favorable outcome. Recently, the approval of PARP inhibitors in the treatment of ovarian cancer patients demonstrated improved outcomes, particularly patients whose tumors remain sensitive to Pt -based treatments.

Pt -based chemotherapies function by causing extensive damage to a cancer cell’s DNA. Cancer cells are adept at overcoming DNA damage or employing mechanisms to repair DNA damage induced by Pt -based chemotherapy. One of the most common obstacles to DNA -damaging chemotherapy is mutations to a gene called p53. Cellular processes governed by the p53 gene are critical in assessing DNA damage and determining if a cell should cease from dividing or self -destruct . When p53 does not function properly, cancer cells continue to divide despite the treatment with DNA -damaging chemotherapy, making these drugs ineffective and leading to treatment resistance. This occurs in nearly all cases of the most difficult ovarian cancer to treat — high grade serous ovarian cancer (HGSOC) — which accounts for up to 70% of ovarian cancer cases and approximately 90% of ovarian cancer deaths. P53 mutations are associated with resistance to Pt -based chemotherapy, which leads to treatment failure and increased mortality. Solving this problem is a major goal in the development of new treatments for ovarian cancer.

Unfortunately, the development of resistance to Pt -based agents is nearly inevitable, leading to disease recurrence and increased mortality. Ultimately, most women with advanced ovarian cancer develop recurrent disease with progressively shorter disease -free intervals. Those whose tumors recur within 6 months of Pt -based therapy are considered Pt -resistant /refractory and have a very poor prognosis.

The response rate to second line therapy for Pt -resistant ovarian cancer patients is in the 10 -15 % range and overall survival is approximately 12 months. The development of new chemotherapies and targeted agents to overcome Pt resistance in ovarian cancer is a significant unmet medical need.

We have presented data demonstrating that VAL -083 ’s distinct mechanism of action allows activity in tumors that are resistant to other therapies. We have shown that cytotoxicity of VAL -083 against ovarian cancer is independent of sensitivity to cisplatin or p53 status in vitro. We have demonstrated that VAL -083 is active in Pt -resistant ovarian cells harboring a range of p53 -mutations .

Our research has demonstrated that VAL -083 not only overcomes Pt resistance, but the combination of VAL -083 with Pt -based chemotherapy displays synergy in multiple models in vitro and in vivo. This further suggests a distinct mechanism of action and potential use as part of a VAL -083 /Pt -combination therapy.

The combination of VAL -083 with either cisplatin (A) or oxaliplatin (B) in the human H460 (WT p53) NSCLC model demonstrated significant super additivity (p≤0.05) and/or synergism (CI<1) for both combinations. This cytotoxic effect of VAL -083 in combination with either platinum drug was observed also in A549 (WT p53) and H1975 (mutant p53) NSCLC cells, independently of p53 status (not shown). Data, where applicable, are shown as mean ± SE; N=7.

While Pt -based chemotherapy is the standard treatment for ovarian cancer, PARP inhibitors have recently provided a new treatment option for a subset of patients with platinum -sensitive recurrent ovarian cancer. VAL -083 also demonstrates synergistic activity with certain PARP inhibitors, including olaparib (Lynparza) and talazoparib in vitro , suggesting VAL -083 may have utility in the treatment of ovarian cancer in combination with PARP inhibitors.

We believe that these data demonstrate the potential of VAL -083 to treat platinum -resistant ovarian cancers as a single -agent against platinum -resistant tumors in combination with platinum -based chemotherapeutic regimens or in combination with PARP inhibitors.

Other Indications for VAL-083 — Potential Future Opportunities

VAL-083 in Lung Cancer

Lung cancer is a leading cause of cancer death around the world and effective treatment for lung cancer remains a significant global unmet need despite advances in therapy. Incidence of lung cancer in the United States is approximately 47 per 100,000 with the majority (85%) being NSCLC, the most common type of lung cancer. Globally, the market for lung cancer treatment may exceed $24 billion by 2033 according to a report published by Evaluate Pharma.

The activity of VAL -083 against solid tumors, including lung cancer, has been established in both preclinical and human clinical studies conducted by the NCI. DelMar has developed new nonclinical data to support the utility of VAL -083 in the modern treatment of lung cancer. In an established murine xenograft model of NSCLC, the activity of VAL -083 was compared to standard platinum -based therapy with cisplatin against human NSCLC cell lines A549

(TKI -sensitive ) and H1975 (TKI -resistant ). In the study, VAL -083 demonstrated superior efficacy and safety in the treatment of TKI -susceptible (A549) tumors and in TKI -resistant (H1975) tumors.

Central Nervous System Metastases of Solid Tumors

The successful management of systemic tumors by modern targeted therapies has led to increased incidence of mortality due to CNS metastases of lung cancer and other solid tumors. In June 2013, we split our Phase 1/2 clinical study protocol into two separate studies: one focusing solely on refractory GBM and the other focusing on secondary brain cancers caused by other tumors that have spread to the brain.

Based on historical clinical activity and our own research, we believe that VAL -083 may be suitable for the treatment of patients with CNS metastases who currently have limited treatment options. Subject to the availability of financial and operating resources, we plan to develop a separate protocol for the continued exploration of VAL -083 in patients with secondary brain cancer caused by a solid tumor spreading to the brain.

Pediatric Brain Tumors

Tumors of the brain and spine make up approximately 20 percent of all childhood cancers and they are the second most common form of childhood cancer after leukemia.

The activity of VAL -083 against childhood and adolescent brain tumors has been established in both preclinical and human clinical studies conducted by the NCI. We have presented data indicating that VAL -083 offers potential therapeutic alternatives for the treatment of pediatric brain tumors including SHH -p53 mutated medulloblastoma. In March 2016, the FDA granted orphan drug designation for the use of VAL -083 in the treatment of medulloblastoma. Subject to the availability of resources, we intend to collaborate with leading academic researchers for the continued exploration of VAL -083 as a potential treatment of childhood brain tumors.

Additional Indications for VAL -083

In historical studies sponsored by the NCI in the United States, VAL -083 exhibited clinical activity against a range of tumor types including central nervous system tumors, solid tumors, and hematologic malignancies. We have established new nonclinical data supporting the activity of VAL -083 in different types of cancer that are resistant to modern targeted therapies and we believe that the unique cytotoxic mechanism of VAL -083 may provide benefit to patients in a range of indications. We intend to continue to research these opportunities, and if appropriate, expand our clinical development efforts to include additional indications.

VAL -083 Target Markets

DNA -targeting agents such as alkylating agents or platinum -based chemotherapy form the mainstay of chemotherapy treatments used in the treatment of cancers. For example, TMZ had peak annual sales of $1.1 billion in 2010, while bendamustine, had peak annual sales of $0.8 billion in 2014.

Our product candidate, VAL -083 , is a first -in-class DNA targeting agent with a novel mechanism of action. VAL -083 ’s anti -cancer activity was established in a range of tumor types in prior NCI -sponsored clinical studies. Based on this novel mechanism, we have demonstrated that the anti -cancer activity is maintained against tumor cells that are resistant to other DNA -targeting agents. We believe this positions VAL -083 as a potential chemotherapy -of-choice for patients whose tumors are resistant to current standard -of-care chemotherapy in orphan and major cancer indications.

Our ongoing research and development activities are focused on indications where VAL -083 demonstrated promising activity in prior NCI -sponsored studies and where our research suggests an opportunity to address significant unmet medical needs due to the failure of existing treatments.

Glioblastoma Multiforme

GBM is the most common and the most lethal form of glioma. According to the Central Brain Tumor Registry of The United States, GBM occurs with an incidence of 3.20 per 100,000 person -years . Approximately 13,000 new cases of GBM were diagnosed in the United States and 16,000 in Europe during 2017.

Newly diagnosed patients suffering from GBM are initially treated through invasive brain surgery, although disease progression following surgical resection is nearly 100%. Temozolomide (Temodar ® ) in combination with radiation is the front -line therapy for GBM following surgery. Global revenues of branded Temodar reached $1.1 billion in 2010. Approximately 60% of GBM patients treated with Temodar ® experience tumor progression within one year. Median overall survival in newly -diagnosed , unmethylated GBM patients is 12.2 months.

Bevacizumab (Avastin ® ) has been approved for the treatment of GBM in patients failing Temodar ® . In clinical studies, approximately 20% of patients failing Temodar ® respond to Avastin ® therapy and no improvement in median survival was reported.

The market for refractory (Avastin -failed ) GBM is limited to those jurisdictions where Avastin is approved for the treatment of GBM. The United States, Canada, Australia, Japan and Switzerland represent the major markets where Avastin is used in the treatment of GBM.

Ovarian Cancer

The American Cancer Society estimates that approximately 22,000 women will receive a new diagnosis of ovarian cancer and approximately 14,000 women will die from ovarian cancer in the United States each year. Ovarian cancer ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system.

The potential of VAL -083 in the treatment of ovarian cancer has been established in prior NCI -sponsored clinical studies and by our recent research. The FDA has granted orphan drug status to VAL -083 as a potential treatment for ovarian cancer and we have recently received notice of allowance for our IND to initiate a Phase 1 -2 clinical study to investigate the safety and effectiveness of VAL -083 in patients with recurrent platinum resistant ovarian cancer (VAL -083 REPROVe study).

Ovarian cancers are commonly treated with a platinum -based chemotherapy regimen. Initial tumor response rates are relatively high. However, the development of resistance to Pt -based chemotherapy in ovarian cancer patients is nearly inevitable. Our research suggests that VAL -083 may offer a potential treatment option for ovarian cancer patients who are resistant to platinum -based chemotherapy and as a potential combination therapy with other agents. We believe the profile of VAL -083 offers the potential to capture meaningful market share in the multi -billion ovarian cancer market.

Lung Cancer

Lung cancer is the most common cancer in the world with 1.8 million cases in 2012, representing 13% of all cancers. According to the American Lung Association, lung cancer is the leading cancer killer in both men and women in the U.S. During 2018, an estimated 234,030 new cases of lung cancer were expected to be diagnosed.

The potential of VAL -083 in the treatment of NSLSC has been established in both human clinical studies conducted by the NCI and by the drug’s commercial approval in China. We believe the profile of VAL -083 offers the potential to capture meaningful market share in the multi -billion NSCLC market.

VAL-083 Manufacturing

VAL -083 is a small -molecule chemotherapeutic. Chemical synthesis of the active pharmaceutical ingredient (“API”) was initially established by the NCI. We have made improvements to this process and have obtained patents on these improvements. The current manufacturing process involves fewer than five synthetic steps.

VAL -083 drug product is a lyophilized (freeze -dried ) formulation that is reconstituted for intravenous injection. We anticipate that overall cost of goods for an eventual commercial product will be similar to other injectable, small -molecule pharmaceuticals.

Until recently, supply of VAL -083 for our clinical studies has been provided through our collaboration with Guangxi Wuzhou Pharmaceutical Company. Guangxi Wuzhou Pharmaceutical Company as a manufacturer has established a commercial -scale manufacturing process based on the North American process originally developed for the NCI that has been licensed by the CFDA for commercial supply of VAL -083 in China. However, to -date , they have not achieved the quality of systems necessary to meet FDA manufacturing standards.

To address the need to meet FDA standards, we have engaged third -party contract manufacturers with the capabilities to establish the processes, procedures and quality systems necessary to meet U.S., Canadian, E.U. and other international manufacturing requirements in accordance with Good Manufacturing Practice (“cGMP”) regulations. We have now received drug supply manufactured under full cGMP conditions. We intend to use this drug supply for all future clinical studies.

We have developed and patented certain intellectual property related to quality controls that are used in the release of VAL -083 for our clinical studies in the United States. This intellectual property is also required for product release under CFDA guidelines and we have granted access to our intellectual property for this purpose.

Research & Development Collaborations

Guangxi Wuzhou Pharmaceutical Company

Pursuant to a memorandum of understanding and collaboration agreement, dated October 25, 2012, we have established a strategic collaboration with Guangxi Wuzhou Pharmaceutical Company, a subsidiary of publicly traded Guangxi Wuzhou Zhongheng Group Co., Ltd. (SHG: 600252) (the “Guangxi Agreement”). VAL -083 is approved for the treatment of chronic myelogenous leukemia (“CML”) and lung cancer in China and Guangxi Wuzhou Pharmaceutical Company is the only manufacturer licensed by the CFDA to produce the product for the China market. Through the Guangxi Agreement, we have been provided drug product at the production price for our VAL -083 clinical studies in the United States and China and we have also secured certain commercial rights in China.

Pursuant to the Guangxi Agreement, we granted to Guangxi Wuzhou Pharmaceutical Company a royalty -free license to certain of our intellectual property, as it relates to quality control and drug production methods for VAL -083 , and we agreed that Guangxi Wuzhou Pharmaceutical Company will be our exclusive supplier of VAL -083 for clinical studies and commercial sales, subject to Guangxi Wuzhou Pharmaceutical Company obtaining and maintaining cGMP certification by the FDA, EMA or other applicable regulatory agencies, and Guangxi Wuzhou Pharmaceutical Company being able to meet volumes ordered by us. We will continue to work with Guangxi Wuzhou Pharmaceutical Company to achieve US FDA compliance in order to potentially have them as our future supplier for global sales of VAL -083 .

This Guangxi Agreement also provides us with certain exclusive commercial rights related to drug supply. Specifically, the Guangxi Agreement establishes an exclusive supply relationship between us and Guangxi Wuzhou Pharmaceutical Company for the Chinese market and all markets outside China. Guangxi Wuzhou Pharmaceutical Company agreed that it may not sell VAL -083 for markets outside of China to any other purchaser other than us, provided that, during the first three years following regulatory clearance for marketing of VAL -083 in a particular country or region, we meet proposed sales volumes set by Guangxi Wuzhou Pharmaceutical Company for the country or region. In addition, Guangxi Wuzhou Pharmaceutical Company granted us a pre -emptive right in China (subject to our acceptance of proposed sales volume and prices) to purchase VAL -083 produced by Guangxi Wuzhou Pharmaceutical Company.

The term of the Guangxi Agreement (except as it relates to the exclusive rights in the China market) is indefinite, subject to termination upon written agreement of all parties, or if either party breaches any material term and fails to remedy such breach within 30 days of receipt of notice of the breach, or if any action to be taken thereunder is not agreed to by both parties, provided that such matter is referred to the chief executive officer of both parties, and they are unable to resolve such matter within 90 days. No payments have been made to date under the Guangxi Agreement.

Duke University Collaboration

In April 2017, we entered into a three -year collaboration with Duke University to evaluate VAL -083 as a front -line treatment for newly diagnosed patients with GBM. Under the terms of the collaboration, we will fund a series of preclinical studies to be conducted by Duke University’s Glioblastoma Drug Discovery Group to identify molecular characteristics of GBM tumors that are more likely to respond to VAL -083 , and not the standard of care, temozolomide, as a front -line treatment or through combination therapies.

Patents and Proprietary Rights

Our success will depend in part on our ability to protect our existing product candidate and the products we acquire or license by obtaining and maintaining a strong proprietary position. To develop and maintain our position, we intend to continue relying upon patent protection, orphan drug status, Hatch -Waxman exclusivity, trade secrets, know -how , continuing technological innovations and licensing opportunities.

We have filed patent applications claiming the use of, and improvements related to VAL -083 . Our patent filings also include proposed treatment regimens, improvements to the manufacturing process, formulation and composition of the active pharmaceutical ingredient, and finished dosage forms of VAL -083 . We are prosecuting our patent applications in the United States and other jurisdictions which we deem important for the potential commercial success of VAL -083 .

Our patents and patent applications can be summarized in fourteen series as follows:

•         Series I is generally directed to synthesis of VAL -083 .

•         Series II is generally directed to use of VAL -083 to treat a range of diseases and conditions, including but not limited to malignancies.

•         Series III is generally directed to analytical methods for VAL -083 .

•         Series IV is generally directed to the use of VAL -083 to treat GBM or medulloblastoma.

•         Series V is generally directed to the veterinary use of VAL -083 .

•         Series VI is generally directed to the use of VAL -083 to treat tyrosine -kinase-inhibitor-resistant malignancies.

•         Series VII is generally directed to the use of VAL -083 to treat recurrent malignant glioma and progressive secondary brain tumor.

•         Series VIII is generally directed to the use of VAL -083 to treat non -small-cell lung cancer.

•         Series IX is generally directed to the use of VAL -083 and radiation to treat NSCLC and GBM.

•         Series X is generally directed to the use of VAL -083 in NSCLC and ovarian cancer:

•         Series XI is generally directed to the use of VAL -083 in the treatment of CNS malignancies:

•         Series XII is generally directed to the analysis and resolution of VAL -083 preparations:

•         Series XIII is generally directed to combinations:

•         Series XIV — PCT

One of the inventors listed in our Series IX applications is an employee of the University of California, San Francisco. If a patent issues from a patent application in this series with a claim that the University of California employee conceived of, in whole or in part, then the Regents of the University of California will share ownership of any such patent with us. Our research agreements with the University of California address this issue by providing us with an exclusive option, for a limited period of time, to negotiate a royalty -bearing exclusive license for commercialization of the invention covered by that patent.

In addition to patent protection, we may also seek orphan drug status whenever it is available. If a product which has an orphan drug designation subsequently receives the first regulatory approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, meaning that the applicable regulatory authority

may not approve any other applications to market the same drug for the same indication, except in very limited circumstances, for a period of seven years in the U.S. and Canada, and 10 years in the E.U. Orphan drug designation does not prevent competitors from developing or marketing different drugs for the same indication or the same drug for a different clinical indication.

VAL -083 has been granted protection under the Orphan Drug Act by the FDA and the European Medicines Agency for the treatment of gliomas, including GBM. The FDA has also granted Orphan Drug protection to VAL -083 for the treatment of medulloblastoma and ovarian cancer.

In February 2012, the FDA granted orphan drug status to VAL -083 for the treatment of glioma. In January 2013, the EMA also granted orphan drug protection to VAL -083 for the treatment of glioma. In the spring of 2016, the FDA Office of Orphan Products Development granted orphan drug designations to VAL -083 for the treatment of ovarian cancer and medulloblastoma.

In addition to our patents and orphan drug protection, we intend to rely on the Hatch -Waxman Amendments for five years of data exclusivity for VAL -083 .Under the Hatch -Waxman Amendments, newly approved drugs and indications benefit from a statutory period of non -patent marketing exclusivity. These amendments provide five -year data exclusivity to the first applicant to gain approval of an NDA for a new chemical entity, meaning that the FDA has not previously approved any other new drug containing the same active ingredient. The Hatch -Waxman Amendments prohibit the approval of an abbreviated new drug application, also known as an ANDA or generic drug application, during the five -year exclusive period if no patent is listed. If there is a patent listed and the ANDA applicant certifies that the NDA holder’s listed patent for the product is invalid or will not be infringed, the ANDA can be submitted four years after NDA approval. Protection under the Hatch -Waxman Amendments will not prevent the filing or approval of another full NDA; however, the applicant would be required to conduct its own pre -clinical studies and adequate and well -controlled clinical studies to demonstrate safety and effectiveness. The Hatch -Waxman Amendments also provide three years of data exclusivity for the approval of NDAs with new clinical studies for previously approved drugs and supplemental NDAs, for example, for new indications, dosages or strengths of an existing drug, if new clinical investigations were conducted by or on behalf of the sponsor and were essential to the approval of the application. This three -year exclusivity covers only the new changes associated with the supplemental NDA and does not prohibit the FDA from approving ANDAs for drugs containing the original active ingredient.

We also rely on trade secret protection for our confidential and proprietary information. We believe that the substantial costs and resources required to develop technological innovations, such as the manufacturing processes associated with VAL -083 , will help us to protect the competitive advantage of our product candidate.

The protection of intellectual property rights in China (where our clinical product candidate, VAL -083 , is manufactured pursuant to a collaboration agreement with the only manufacturer presently licensed by the CFDA to produce the product for the China market, and where VAL -03 is approved for the treatment of CML and lung cancer) is relatively weak compared to the United States, which may negatively affect our ability to generate revenue from VAL -083 in China.

Our policy is to require our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. These agreements provide that all confidential information developed or made known to the individual during the course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees and consultants, the agreements provide that all inventions conceived by the individual shall be our exclusive property.

Government Regulation and Product Approval

Regulation by governmental authorities in the U.S. and other countries is a significant factor, affecting the cost and time of our research and product development activities, and will be a significant factor in the manufacture and marketing of any approved products. Our product candidates will require regulatory approval by governmental agencies prior to commercialization. In particular, our products are subject to rigorous preclinical and clinical testing and other approval requirements by the FDA and similar regulatory authorities in other countries. Various statutes and regulations also govern or influence the manufacturing, safety, reporting, labeling, transport and storage,

record keeping and marketing of our products. The lengthy process of seeking these approvals, and the subsequent compliance with applicable statutes and regulations, require the expenditure of substantial resources. Any failure by us to obtain, or any delay in obtaining, the necessary regulatory approvals could harm our business.

The regulatory requirements relating to the testing, manufacturing and marketing of our products may change from time to time and this may impact our ability to conduct clinical studies and the ability of independent investigators to conduct their own research with support from us.

The clinical development, manufacturing and marketing of our products are subject to regulation by various authorities in the U.S., the E.U. and other countries, including, in the U.S., the FDA, in Canada, Health Canada, and, in the E.U., the EMA. The Federal Food, Drug, and Cosmetic Act, the Public Health Service Act in the U.S. and numerous directives, regulations, local laws and guidelines in Canada and the E.U. govern the testing, manufacture, safety, efficacy, labeling, storage, record keeping, approval, advertising and promotion of our products. Product development and approval within these regulatory frameworks takes a number of years and involves the expenditure of substantial resources.

Regulatory approval will be required in all the major markets in which we seek to develop our products. At a minimum, approval requires the generation and evaluation of data relating to the quality, safety, and efficacy of an investigational product for its proposed use. The specific types of data required and the regulations relating to this data will differ depending on the territory, the drug involved, the proposed indication and the stage of development.

In general, new chemical entities are tested in animals until adequate evidence of safety is established to support the proposed clinical study protocol designs. Clinical studies for new products are typically conducted in three sequential phases that may overlap. In Phase 1, the initial introduction of the pharmaceutical into either healthy human volunteers or patients with the disease (20 to 50 subjects), the emphasis is on testing for safety (adverse effects), dosage tolerance, metabolism, distribution, excretion and clinical pharmacology. Phase 2 involves studies in a limited patient population (50 to 200 patients) to determine the initial efficacy of the pharmaceutical for specific targeted indications, to determine dosage tolerance and optimal dosage and to identify possible adverse side effects and safety risks. Once a compound shows preliminary evidence of some effectiveness and is found to have an acceptable safety profile in Phase 2 evaluations, Phase 3 studies are undertaken to more fully evaluate clinical outcomes in a larger patient population in adequate and well -controlled studies designed to yield statistically sufficient clinical data to demonstrate efficacy and safety.

In the U.S., specific preclinical data, manufacturing and chemical data, as described above, need to be submitted to the FDA as part of an IND application, which, unless the FDA objects, will become effective 30 days following receipt by the FDA. Phase 1 studies in human volunteers may commence only after the application becomes effective. Prior regulatory approval for human healthy volunteer studies is also required in member states of the E.U. Currently, in each member state of the E.U., following successful completion of Phase 1 studies, data are submitted in summarized format to the applicable regulatory authority in the member state in respect of applications for the conduct of later Phase 2 studies. The regulatory authorities in the E.U. typically have between one and three months in which to raise any objections to the proposed study, and they often have the right to extend this review period at their discretion. In the U.S., following completion of Phase 1 studies, further submissions to regulatory authorities are necessary in relation to Phase 2 and 3 studies to update the existing IND.

Authorities may require additional data before allowing the studies to commence and could demand that the studies be discontinued at any time if there are significant safety issues. In addition to the regulatory review, studies involving human subjects must be approved by an independent body. The exact composition and responsibilities of this body will differ from country to country. In the U.S., for example, each study will be conducted under the auspices of an independent institutional review board (IRB) at each institution at which the study is conducted. The IRB considers among other things, the design of the study, ethical factors, the privacy of protected health information as defined under the Health Insurance Portability and Accountability Act, the safety of the human subjects and the possible liability risk for the institution. Equivalent rules to protect subjects’ rights and welfare apply in each member state of the E.U. where one or more independent ethics committees, which typically operate similarly to an IRB, will review the ethics of conducting the proposed research. Other regulatory authorities around the rest of the world have slightly differing requirements involving both the execution of clinical studies and the import/export of pharmaceutical products. It is our responsibility to ensure we conduct our business in accordance with the regulations of each relevant territory.

In order to gain marketing approval, we must submit a dossier to the relevant authority for review, which is known in the U.S. as a new drug application (NDA) and in the E.U. as a marketing authorization application (MAA). The format is usually specific and laid out by each authority, although in general it will include information on the quality of the chemistry, manufacturing and pharmaceutical aspects of the product as well as the nonclinical and clinical data. Once the submitted NDA is accepted for filing by the FDA, it undertakes the review process that currently takes on average 10 months, unless an expedited priority review is granted which takes six months to complete. Approval can take several months to several years, if multiple 10 -month review cycles are needed before final approval is obtained, if at all.

The approval process can be affected by a number of factors. The NDA may require additional preclinical, manufacturing data or clinical studies which may be requested at the end of the 10 -month NDA review cycle, thereby delaying approval until additional data are submitted and may involve substantial unbudgeted costs.

In addition to obtaining approval for each product, in many cases each drug manufacturing facility must be approved. The regulatory authorities usually will conduct an inspection of relevant manufacturing facilities, and review manufacturing procedures, operating systems and personnel qualifications. Further inspections may occur over the life of the product. An inspection of the clinical investigation sites by a competent authority may be required as part of the regulatory approval procedure. As a condition of marketing approval, the regulatory agency may require post -marketing surveillance to monitor for adverse effects or other additional studies as deemed appropriate. After approval for the initial indication, further clinical studies may be necessary to gain approval for any additional indications. The terms of any approval, including labeling content, may be more restrictive than expected and could affect the marketability of a product.

The FDA offers a number of regulatory mechanisms that provide expedited or accelerated approval procedures for selected drugs in the indications on which we are focusing our efforts. These include accelerated approval under Subpart H of the agency’s NDA approval regulations, fast track drug development procedures, breakthrough drug designation and priority review. At this time, we have not determined whether any of these approval procedures will apply to our current drug candidate.

By leveraging existing preclinical and clinical safety and efficacy data, we seek to build upon an existing knowledge base to accelerate our research. In addition, through our focus on end -stage population which has no current treatment options, regulatory approval for commercialization may sometimes be achieved in an accelerated manner. Accelerated approval by the FDA in this category may be granted on objective response rates and duration of responses rather than demonstration of survival benefit. As a result, studies of drugs to treat end -stage refractory cancer indications have historically involved fewer patients and generally have been faster to complete than studies of drugs for other indications. We are aware that the FDA and other similar agencies are regularly reviewing the use of objective endpoints for commercial approval and that policy changes may impact the size of studies required for approval, timelines and expenditures significantly.

The U.S., E.U. and other jurisdictions may grant orphan drug designation to drugs intended to treat a “rare disease or condition,” which, in the U.S., is generally a disease or condition that affects no more than 200,000 individuals. In the E.U., orphan drug designation can be granted if: the disease is life threatening or chronically debilitating and affects no more than 50 in 100,000 persons in the E.U.; without incentive, it is unlikely that the drug would generate sufficient return to justify the necessary investment; and no satisfactory method of treatment for the condition exists or, if it does, the new drug will provide a significant benefit to those affected by the condition. If a product that has an orphan drug designation subsequently receives the first regulatory approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, meaning that the applicable regulatory authority may not approve any other applications to market the same drug for the same indication, except in very limited circumstances, for a period of seven years in the U.S. and 10 years in the E.U. Orphan drug designation does not prevent competitors from developing or marketing different drugs for the same indication or the same drug for different indications. Orphan drug designation must be requested before submitting an NDA or MAA. After orphan drug designation is granted, the identity of the therapeutic agent and its potential orphan use are publicly disclosed. Orphan drug designation does not convey an advantage in, or shorten the duration of, the review and approval process. However, this designation provides an exemption from marketing and authorization fees charged to NDA sponsors under the Prescription Drug Act (PDUFA Fees).

Maintaining substantial compliance with appropriate federal, state and local statutes and regulations requires the expenditure of substantial time and financial resources. Drug manufacturers are required to register their establishments with the FDA and certain state agencies, and after approval, the FDA and these state agencies conduct periodic unannounced inspections to ensure continued compliance with ongoing regulatory requirements, including cGMPs. In addition, after approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. The FDA may require post -approval testing and surveillance programs to monitor safety and the effectiveness of approved products that have been commercialized. Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including:

•         record -keeping requirements;

•         reporting of adverse experiences with the drug;

•         providing the FDA with updated safety and efficacy information;

•         reporting on advertisements and promotional labeling;

•         drug sampling and distribution requirements; and

•         complying with electronic record and signature requirements.

In addition, the FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. There are numerous regulations and policies that govern various means for disseminating information to health -care professionals as well as consumers, including to industry sponsored scientific and educational activities, information provided to the media and information provided over the Internet. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label.

The FDA has very broad enforcement authority and the failure to comply with applicable regulatory requirements can result in administrative or judicial sanctions being imposed on us or on the manufacturers and distributors of our approved products, including warning letters, refusals of government contracts, clinical holds, civil penalties, injunctions, restitution and disgorgement of profits, recall or seizure of products, total or partial suspension of production or distribution, withdrawal of approvals, refusal to approve pending applications, and criminal prosecution resulting in fines and incarceration. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off -label uses, and a company that is found to have improperly promoted off -label uses may be subject to significant liability. In addition, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market.

Sales of our product candidates, if approved, will depend, in part, on the extent to which such products will be covered by third -party payors, such as government health care programs, commercial insurance and managed healthcare organizations. These third -party payors are increasingly limiting coverage or reducing reimbursements for medical products and services. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost -containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Third -party payors decide which therapies they will pay for and establish reimbursement levels. Third -party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for any drug candidates that we develop will be made on a payor -by-payor basis. Each payor determines whether or not it will provide coverage for a therapy, what amount it will pay the manufacturer for the therapy, and on what tier of its formulary it will be placed. The position on a payor’s list of covered drugs, or formulary, generally determines the co -payment that a patient will need to make to obtain the therapy and can strongly influence the adoption of such therapy by patients and physicians. Adoption of price controls and cost -containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. Decreases in third -party reimbursement for our product candidates or a decision by a third -party payor to not cover our product candidates could reduce physician usage of our product candidates, once approved, and have a material adverse effect on our sales, results of operations and financial condition.

Because of our current and future arrangements with healthcare professionals, principal investigators, consultants, customers and third -party payors, we will also be subject to healthcare regulation and enforcement by the federal government and the states and foreign governments in which we will conduct our business, including our clinical research, proposed sales, marketing and educational programs. Failure to comply with these laws, where applicable, can result in the imposition of significant civil penalties, criminal penalties, or both. The U.S. laws that may affect our ability to operate, among others, include: the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, which governs the conduct of certain electronic healthcare transactions and protects the security and privacy of protected health information; certain state laws governing the privacy and security of health information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts; the federal healthcare programs’ Anti -Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs; federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third -party payors that are false or fraudulent; federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters; the Physician Payments Sunshine Act, which requires manufacturers of drugs, devices, biologics, and medical supplies to report annually to the U.S. Department of Health and Human Services information related to payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members; and state law equivalents of each of the above federal laws, such as anti -kickback and false claims laws which may apply to items or services reimbursed by any third -party payor, including commercial insurers.

In addition, many states have similar laws and regulations, such as anti -kickback and false claims laws that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, to the extent that our product is sold in a foreign country, we may be subject to similar foreign laws.

We are also subject to numerous environmental and safety laws and regulations, including those governing the use and disposal of hazardous materials. The cost of compliance with and any violation of these regulations could have a material adverse effect on our business and results of operations. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards prescribed by state and federal regulations, accidental contamination or injury from these materials may occur. Compliance with laws and regulations relating to the protection of the environment has not had a material effect on our capital expenditures or our competitive position. However, we are not able to predict the extent of government regulation, and the cost and effect thereof on our competitive position, which might result from any legislative or administrative action pertaining to environmental or safety matters.

Competition

The development and commercialization of new drug products is highly competitive. We expect that we will face significant competition from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide with respect to VAL -083 and any other product candidates that we may seek to develop or commercialize in the future. Specifically, due to the large unmet medical need, global demographics and relatively attractive reimbursement dynamics, the oncology market is fiercely competitive and there are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of product candidates for the treatment of cancer. Our competitors may succeed in developing, acquiring or licensing technologies and drug products that are more effective, have fewer or more tolerable side effects or are less costly than any product candidates that we are currently developing or that we may develop, which could render our product candidates obsolete and noncompetitive.

All of the top ten global pharmaceutical companies and many of the mid -size pharmaceutical companies have a strong research and development and commercial presence in oncology. Smaller companies also focus on oncology, including companies such as ARIAD Pharmaceuticals, Inc., Agios Pharmaceuticals, Inc., BIND Therapeutics, Inc., Clovis

Oncology, Inc., Endocyte, Inc., Epizyme, Inc., ImmunoGen, Inc., Incyte Corporation, Infinity Pharmaceuticals, Inc., MacroGenics, Inc., Merrimack Pharmaceuticals, Inc., OncoMed Pharmaceuticals, Inc., Onconova Therapeutics, Inc., Pharmacyclics, Inc., Puma Biotechnology, Inc., Seattle Genetics, Inc. and TESARO, Inc.

Several companies are marketing and developing oncology immunotherapy products. Companies with approved marketed oncology products for GBM are Merck (Temodar ® ) and Genentech (Avastin ® ). Companies with oncology immunotherapy product candidates in clinical development include, but are not limited to, Northwest Biotherapeutics (DCVax -L ), Celldex Therapeutics (Rindopepimut (CDX -110 )) and ImmunoCellular Therapeutics (ICT -107 ).

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 any products that we may develop. Our competitors also may obtain FDA or other marketing approval for their products before we are able to obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Many of our existing and potential future competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical studies, obtaining marketing 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 or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical study sites and patient registration for clinical studies, as well as in acquiring technologies complementary to, or necessary for, our programs.

We expect that our ability to compete effectively will depend upon our ability to:

•         successfully and rapidly complete adequate and well -controlled clinical studies that demonstrate statistically significant safety and efficacy and to obtain all requisite regulatory approvals in a cost -effective manner;

•         maintain a proprietary position for our manufacturing processes and other technology;

•         produce our products in accordance with FDA and international regulatory guidelines;

•         attract and retain key personnel; and

•         build or access an adequate sales and marketing infrastructure for any approved products.

Failure to do one or more of these activities could have an adverse effect on our business, financial condition or results of operations.

Corporate History

We are a Nevada corporation formed on June 24, 2009 under the name Berry Only, Inc. (“Berry”). On January 25, 2013, we entered into and closed an exchange agreement (the “Exchange Agreement”), with Del Mar Pharmaceuticals (BC) Ltd. (“Del Mar (BC)”), 0959454 B.C. Ltd. (“Callco”), and 0959456 B.C. Ltd. (“Exchangeco”) and the security holders of Del Mar (BC). Upon completion of the Exchange Agreement, Del Mar (BC) became a wholly -owned subsidiary of ours (the “Reverse Acquisition”). Prior to the Reverse Acquisition undertaken on January 25, 2013, Berry did not have any significant assets or operations.

We are the parent company of Del Mar (BC), a British Columbia, Canada corporation incorporated on April 6, 2010, that is focused on the development of drugs for the treatment of cancer. We are also the parent company to Callco and Exchangeco which are British Columbia, Canada corporations. Callco and Exchangeco were formed to facilitate the Reverse Acquisition.

On May 20, 2016, we effected a one -for-four reverse split of our common stock. All share amounts in this report give effect to the reverse split unless otherwise indicated.

On May 8, 2019, we effected a one -for-ten reverse stock split (the “Reverse Stock Split”) of our issued and outstanding and authorized common stock. All per share amounts and number of shares of common stock in this prospectus reflect the Reverse Stock Split. The Reverse Stock Split does not affect the our authorized preferred stock

of 5,000,000 shares; except that, pursuant to the terms of the Certificate of Designations of Series B Convertible Preferred Stock for the issued and outstanding shares of our Series B Convertible Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”), the conversion price at which shares of Series B Preferred Stock may be converted into shares of common stock will be proportionately adjusted to reflect the Reverse Stock Split.

Research and Development

During the nine -month periods ended March 31, 2019 and 2018, we recognized $2,702,213 and $5,856,197, respectively, in research and development expenses. During the years ended June 30, 2018 and 2017, we recognized $7,132,952 and $5,003,640, respectively, in research and development expenses.

Employees

We have two full -time employees and retain the services of approximately 15 persons on an independent contractor/consultant and contract -employment basis. As such, we currently operate in a “virtual” corporate structure in order to minimize fixed personnel costs.

Legal Proceedings

There are no legal proceedings to which we are a party or any of our property is the subject.

Facilities

Our corporate headquarters are located at Suite 720 -999 West Broadway, Vancouver, British Columbia, Canada, V5Z 1K5. Our clinical operations are managed at 3475 Edison Way, Suite R, Menlo Park, California, 94025. Our current monthly base rent for our corporate headquarters is $4,022 (CDN $5,375) on a month -to-month basis. In addition, Valent Technologies, LLC (“Valent”), which is owned by Dr. Dennis Brown, our Chief Scientific Officer, leases facilities in California and we have access to such facilities pursuant to an informal unwritten arrangement with Valent. Our leased premises, academic relationships, and access to the Valent facility are sufficient to meet the immediate needs of our business, research and operations.

The Board of Directors and Its Committees

Board of Directors Operations and Meetings

Our Board currently consists of six members. Our directors hold office until their successors have been elected and qualified or until the earlier of their resignation or removal.

We have no formal policy regarding board diversity. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, knowledge of our business and understanding of the competitive landscape.

Our Board met 27 times in fiscal 2018. Each of the directors attended at least 75% of the aggregate of (i) the total number of meetings of our Board (held during the period for which such directors served on the Board), and (ii) the total number of meetings of all committees of our Board on which the director served (during the periods for which the director served on such committee or committees).

The Board oversees our business and monitors the performance of our management. In accordance with our corporate governance procedures, the Board does not involve itself in the day -to-day operations of DelMar. Our executive officers and management oversee our day -to-day operations. Our directors fulfill their duties and responsibilities by attending meetings of the Board, which are usually held on at least a quarterly basis. Our directors also discuss business and other matters with other key executives and our principal external advisers (legal counsel, auditors, financial advisors and other consultants).

Independent Directors

Our Board has determined that Robert Hoffman, John Bell, Lynda Cranston, Napoleone Ferrara and Robert Toth are qualified to serve as independent directors. Prior to being appointed Chief Executive Officer, Saiid Zarrabian was also determined by our Board to be independent. The standards relied on by the Board in affirmatively determining whether a director is “independent,” in compliance with Nasdaq’s rules, are comprised of those objective standards set forth in the rules promulgated by Nasdaq. The Board is responsible for ensuring that independent directors do not have a relationship that, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Nasdaq’s rules, as well as SEC rules, impose additional independence requirements for all members of the Audit Committee. Specifically, in addition to the “independence” requirements discussed above, “independent” audit committee members must: (1) not accept, directly or indirectly, any consulting, advisory, or other compensatory fees from DelMar or any subsidiary of DelMar other than in the member’s capacity as a member of the Board and any Board committee; (2) not be an affiliated person of DelMar or any subsidiary of DelMar; and (3) not have participated in the preparation of the financial statements of DelMar or any current subsidiary of DelMar at any time during the past three years. In addition, Nasdaq’s rules require that all audit committee members be able to read and understand fundamental financial statements, including DelMar’s balance sheet, income statement, and cash flow statement. The Board believes that the current members of the Audit Committee meet these additional standards.

Furthermore, at least one member of the Audit Committee must be financially sophisticated, in that he or she has past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual’s financial sophistication, including but not limited to being or having been a chief executive officer, chief financial officer, other senior officer with financial oversight responsibilities. Additionally, the SEC requires that DelMar disclose whether the Audit Committee has, and will continue to have, at least one member who is a “financial expert.” The Board has determined that John Bell meets the SEC’s definition of an audit committee financial expert.

Audit Committee

The Board has formed an Audit Committee, which currently consists of John K. Bell, Chair, Robert E. Hoffman, and Robert Toth, all of whom are independent (as that term is defined under the Nasdaq Marketplace Rules) and financially literate (as such qualification is interpreted by the Board in its business judgment). We are relying upon the exemption in section 6.1 of Canadian National Instrument 52 -110 — Audit Committees from Parts 3 and 5 thereof. In addition, our Board has determined that Mr. Bell qualifies as an audit committee financial expert within the meaning of SEC regulations and The NASDAQ Marketplace Rules.

The Audit Committee oversees and monitors our financial reporting process and internal control system, reviews and evaluates the audit performed by our registered independent public accountants and reports to our Board any substantive issues found during the audit. The Audit Committee will be directly responsible for the appointment, compensation and oversight of the work of our registered independent public accountants. The Audit Committee reviews and approves all transactions with affiliated parties. The Board has adopted a written charter for the Audit Committee.

A copy of the Audit Committee Charter is posted under the “Investors” tab on our website, which is located at www.delmarpharma.com .

Compensation Committee

The Board has formed a Compensation Committee which consists of Robert Toth, Chair, Napoleone Ferrara, and Robert E. Hoffman, all of whom are independent (as that term is defined under the Nasdaq Marketplace Rules). The Compensation Committee assists the Board in fulfilling its oversight responsibilities relating to (i) corporate governance practices and policies and (ii) compensation matters, including compensation of the directors and senior management of the Company and the administration of compensation plans of the Company. The Board has adopted a written charter for the Compensation Committee. A copy of the Compensation Committee Charter is posted under the “Investors” tab on our website, which is located at www.delmarpharma.com .

The Compensation Committee has engaged Marsh & McLennan Agency LLC as its independent compensation consultant. In 2018, Marsh & McLennan Agency LLC reviewed both executive and director compensation and did not provide us any other services. Marsh & McLennan Agency LLC reported directly to the Compensation Committee and provided guidance on trends in executive and non -employee director compensation, the development of specific executive compensation programs, the composition of our compensation peer group and other matters as directed by the Compensation Committee. In 2017, Marsh & McLennan Agency LLC did not provide any services to us.

In 2017, the Compensation Committee engaged Hugessen Consulting to provide certain director compensation services, including with respect to benchmarking, compensation trends and retention practices and Global Advisors to provide advisory services in connection with the development of our 2017 Omnibus Equity Incentive Plan. In 2017, Hugessen Consulting and Global Advisors did not provide us any other services.

Nominating and Corporate Governance Committee

The Board has formed a Nominating and Corporate Governance Committee, which currently consists of Lynda Cranston, Chair, John Bell, and Napoleone Ferrara, all of whom are independent (as that term is defined under the Nasdaq Marketplace Rules). The Board has adopted a written charter for the Nominating and Corporate Governance Committee. A copy of the Nominating and Corporate Governance Committee Charter is posted under the “Investors” tab on our website, which is located at www.delmarpharma.com.

Nomination of Directors

The Nominating and Corporate Governance Committee of the Board of Directors assesses potential candidates to fill perceived needs on the Board of Directors for required skills, expertise, independence and other factors. A director candidate recommended by our stockholders will be considered in the same manner as a nominee recommended by a Board member, management or other sources. Stockholders wishing to recommend a candidate for nomination should contact our Secretary in writing at the Secretary of DelMar at Suite 720 -999 West Broadway Vancouver, British Columbia, Canada V5Z 1K5. Our Nominating and Corporate Governance Committee has discretion to decide which individuals to recommend for nomination as directors.

Board Leadership Structure and Role in Risk Oversight

Robert E. Hoffman serves as the chairman of our Board of Directors. Saiid Zarrabian serves as our Chief Executive Officer and President. We have not adopted a formal policy on whether the Chief Executive Officer and Chairman positions should be separated.

Our Board of Directors is primarily responsible for overseeing our risk management processes. The Board of Directors receives and reviews periodic reports from management, auditors, legal counsel, and others, as considered appropriate regarding our assessment of risks. The Board of Directors focuses on the most significant risks facing us and our general risk management strategy, and also ensures that risks undertaken by us are consistent with the board’s appetite for risk. While the Board of Directors oversees our risk management, management is responsible for the day -to-day risk management processes. We believe this division of responsibilities is the most effective approach for addressing the risks we face and that our board leadership structure supports this approach.

Code of Ethics

We have adopted a Code of Ethics and Business Conduct that applies to all of our executive officers, financial and accounting officers, our directors, our financial managers and all of our employees. The Board of Directors is committed to a high standard of corporate governance practices and, through its oversight role, encourages and promotes a culture of ethical business conduct. A copy of our Code of Ethics and Business Conduct is posted under the “Investors” tab under Corporate Governance on our website, which is located at www.delmarpharma.com .

Stockholder Communication with the Board of Directors and Attendance at Annual Meetings

The Board maintains a process for stockholders to communicate with the Board and its committees. Stockholders of DelMar and other interested persons may communicate with the Board or the chair of the Audit Committee, Compensation Committee, and the Nominating and Corporate Governance Committee by writing to the Secretary of DelMar at Suite 720 -999 West Broadway Vancouver, British Columbia, Canada V5Z 1K5. All communications that relate to matters that are within the scope of the responsibilities of the Board will be presented to the Board no later than the next regularly scheduled meeting. Communications that relate to matters that are within the responsibility of one of the Board committees will be forwarded to the chair of the appropriate committee. Communications that relate to ordinary business matters that are not within the scope of the Board’s responsibilities will be forwarded to the appropriate officer. Solicitations, junk mail and obviously frivolous or inappropriate communications will not be forwarded, but will be made available to any director who wishes to review them.

EXECUTIVE COMPENSATION

The Board of Directors has formed a Compensation Committee. The Compensation Committee is responsible for reviewing and approving management compensation, including salaries, bonuses, and equity compensation. We seek to provide competitive compensation arrangements that attract and retain key talent necessary to achieve our business objectives.

Summary Compensation Table

The following table presents information regarding the total compensation awarded to, earned by, or paid to our Chief Executive Officer and the two most highly -compensated executive officers (other than the Chief Executive Officer) who were serving as executive officers as of June 30, 2018 and June 30, 2017 for services rendered in all capacities to us for the years ended June 30, 2018 and June 30, 2017, reflecting our one -for-ten reverse stock split occurring on May 8, 2019.

In addition, Mr. Bacha did not stand for re -election to the Board of Directors at our 2018 annual meeting of stockholders held on April 11, 2018.

As a result of modifying Mr. Bacha’s stock options, a total of $122,338 has been recognized.

(3)      On January 1, 2015 we entered into a consulting agreement with Dr. Dennis Brown, our chief scientific officer. Subsequent to this agreement, it has been amended and is now renewed on an annual basis. Under the most recent renewal, Dr. Brown will continue to serve as our chief scientific officer until December 31, 2018, which period may be extended in accordance with the terms of the agreement. We will pay Dr. Brown an annual consulting fee of $200,000 during calendar year 2018. We may also pay to Dr. Brown a bonus and incentive compensation as determined at the discretion of the Board of Directors. The consulting agreement with Dr. Brown does not specify the amount of time Dr. Brown is required to devote to us, but does require that Dr. Brown provide us with the full benefit of his knowledge, expertise and ingenuity, and prohibits Dr. Brown from engaging in any business, enterprise or activity contrary to or that would detract from our business.

(4)      On February 9, 2017, we entered into an employment agreement with Scott Praill, our chief financial officer. Pursuant to the employment agreement, Mr. Praill will continue to serve as our chief financial officer for an indefinite period until termination of the employment agreement in accordance with its terms. We will pay Mr. Praill an annual base salary of $200,000 (which may be adjusted on an annual basis in the discretion of the Board of Directors) and Mr. Praill will also be eligible to participate in any bonus plan and long -term incentive plan established by us for senior executives. The employment agreement may be terminated by us with or without cause (as defined therein). In the event we terminate the employment agreement without cause, we will be required to pay Mr. Praill, any accrued and unpaid base salary, plus an amount equal to 12 months of Mr. Praill’s base salary plus one additional month’s base salary for each completed year of service, up to 18 months’ base salary.

On November 3, 2017 Mr. Zarrabian was appointed interim chief executive officer and on January 1, 2018 he was also appointed interim president. On November 3, 2017 we entered an agreement with Mr. Zarrabian pursuant to which he will receive an annualized fee of $280,000 and be eligible to receive a bonus targeted up to 30% of the $280,000 annual fee which may be adjusted by the Board based on his individual performance and our performance as a whole, with such performance targets to be established by the Board. Upon execution of the agreement, we paid Mr. Zarrabian an advance of $45,000 of the annual fee. With the $45,000 advance, Mr. Zarrabian purchased shares of our common stock on the market. For the period from November 3, 2017 to May 20, 2018 we paid Mr. Zarrabian a total of $243,510 under the consulting agreement which includes the $45,000 advance, $130,134 in consulting fees, and $68,376 in bonus. Upon his appointment as interim chief executive officer he was granted 12,000 stock options that are exercisable at $8.70 until November 3, 2027 for total compensation expense of $53,567.

On May 21, 2018, we entered into an employment agreement with Mr. Zarrabian pursuant to which Mr. Zarrabian was appointed as our permanent president and chief executive officer. Under the Agreement, Mr. Zarrabian will receive an annual base salary of $470,000 and will be eligible to receive a fiscal year target bonus of up to 50% of base salary (which may be adjusted by the Board to up to 60% of base salary based on overachievement of bonus targets or other performance criteria). Any bonus earned for a fiscal year will be payable in cash, but the Board may pay up to 50% of the bonus, as well as any bonus in excess of 50% of base salary, in the form of stock options granted under our 2017 Omnibus Equity Incentive Plan (or any successor plan). The bonus for our fiscal year ending June 30, 2019 will be based on the period from the effective date of the agreement (May 21, 2018) through June 30, 2019. The employment agreement may be terminated by us with or without cause (as defined therein). In the event we terminate the employment agreement without cause, we will be required to pay Mr. Zarrabian continued payment of his base salary for 12 months, a prorated bonus for the year of termination based on performance through the date of termination, an additional six months of vesting credit for any outstanding options, and continued health coverage during the severance period. In the event that an involuntary termination occurs during a period beginning sixty days before a definitive corporate transaction agreement is entered into that would result in a change in control, or within twelve months following a change in control, the severance period will increase to eighteen months’ severance, Mr. Zarrabian will receive 100% of his target bonus, and his options will be fully vested. During the period from May 21, 2018 to June 30, 2018 Mr. Zarrabian was paid $53,528 under the employment agreement. We have also recorded a pro -rated bonus of $17,255.

Risk Management

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

We describe below transactions and series of similar transactions that we were or will be a party to in which (i) an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons and (ii) the amount involved exceeds $120,000 or one percent of the average of our total assets at year -end for the last two completed fiscal years.

Other than as described below, there has not been, nor is there any currently proposed, transactions or series of similar transactions to which we have been or will be a party.

On September 12, 2010, Del Mar (BC) entered into a Patent Assignment Agreement (the “Assignment”) with Valent Technologies LLC pursuant to which Valent assigned to Del Mar (BC) its rights to patent applications and the prototype drug product related to VAL -083 . In accordance with the Assignment the consideration paid by Del Mar (BC) was $250,000 to acquire the prototype drug product. In accordance with the terms of the Assignment, Valent is entitled to receive a future royalty (in the single digits) on certain revenues derived from the development and commercialization of VAL -083 . In the event that Del Mar (BC) terminates the agreement, Del Mar (BC) may be entitled to receive royalties from Valent’s subsequent development of VAL -083 depending on the development milestones Del Mar (BC) has achieved prior to the termination of the Assignment. The Assignment has a term (on a country -by-country basis), of the later of ten years or until patent rights covered by the Assignment no longer exist, subject to earlier termination in the event Del Mar (BC) breaches its payment obligations and fails to remedy such breach within 60 days, or if either party materially beaches any of its obligations and does not cure such breach within 30 days after receipt of notice thereof.

Pursuant to a loan agreement dated February 3, 2011, between Del Mar (BC) and Valent, Valent loaned Del Mar $250,000 for the purchase of the prototype drug product under the Assignment. The loan is unsecured, bears interest at 3% per year, and is payable on demand. Effective September 30, 2014, we entered into and closed an agreement with Valent to exchange its loan, including accrued interest to September 30, 2014, with Valent for 278,530 shares of our Series A preferred stock. The Series A preferred stock has an annual 3% dividend.

One of our officers, Dr. Dennis Brown, is a principal of Valent and as result Valent is a related party to us.

THE RIGHTS OFFERING

The Subscription Rights

We are distributing to the record holders of our common stock and certain of our warrants, at no charge, non -transferable Subscription Rights to purchase one Unit at a subscription price of $1,000 per Unit. Each Basic Subscription Right will entitle you to purchase one share of our preferred stock and 209 Warrants. Each Warrant will be exercisable for one share of our common stock at an exercise price of $3.10 per share from the date of issuance through the expiration five years from the date of issuance. Each record holder of our common stock and holders of certain outstanding warrants will receive one Subscription Right for every share of our common stock (including each share of common stock issuable upon exercise of certain outstanding warrants) owned by such record holder as of the Record Date. Each Subscription Right entitles the record holder to a Basic Subscription Right and an Over -Subscription Privilege.

Basic Subscription Rights

Your Basic Subscription Rights will entitle you to purchase one share of our Preferred Stock and 209 Warrants. For example, if you owned 100 shares of common stock as of the Record Date, you will receive 100 Subscription Rights and will have the right to purchase 100 shares of our Preferred Stock and Warrants to purchase 20,900 shares of our common stock for $1,000 per Unit, or a total payment of $100,000. You may exercise all or a portion of your Basic Subscription Rights, or you may choose not to exercise any of your Basic Subscription Rights. If you do not exercise your Basic Subscription Rights in full, you will not be entitled to exercise your Over -Subscription Privilege.

Over-Subscription Privilege

If you exercise your Basic Subscription Rights in full, you may also choose to exercise your Over -Subscription Privilege. Subject to proration and the limitations described in this prospectus, we will seek to honor the Over -Subscription Requests in full. If Over -Subscription Requests exceed the number of Units available, however, we will allocate the available Units pro rata among the stockholders and eligible warrant holders as of the Record Date exercising the Over -Subscription Privilege in proportion to the number of shares of our common stock (including each share of common stock issuable upon exercise of certain outstanding warrants) each of those stockholders and/or warrant holders owned on the Record Date, relative to the number of shares owned on the Record Date by all stockholders and warrant holders as of the Record Date exercising the Over -Subscription Privilege. If this pro rata allocation results in any stockholder or warrant holder receiving a greater number of Units than the record holder subscribed for pursuant to the exercise of the Over -Subscription Privilege, then such record holder will be allocated only that number of Units for which the record holder oversubscribed, and the remaining Units will be allocated among all other stockholders or warrant holders exercising the Over -Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Units have been allocated. Broadridge Corporate Issuer Solutions, Inc., the Subscription Agent for the Rights Offering, will determine the over -subscription allocation based on the formula described above.

To the extent the aggregate subscription payment of the actual number of unsubscribed Units available to you pursuant to the Over -Subscription Privilege is less than the amount you actually paid in connection with the exercise of the Over -Subscription Privilege, you will be allocated only the number of unsubscribed Units available to you, and any excess subscription payments will be returned to you, without interest or deduction, with 10 business days after expiration of the Rights Offering.

We can provide no assurances that you will actually be entitled to purchase the number of Units issuable upon the exercise of your Over -Subscription Privilege in full at the expiration of the Rights Offering. We will not be able to satisfy any requests for Units pursuant to the Over -Subscription Privilege if all of our stockholders exercise their Basic Subscription Rights in full, and we will only honor an Over -Subscription Privilege to the extent sufficient Units are available following the exercise of Basic Subscription Rights.

Limitation on the Purchase of Units

You may only purchase the number of Units purchasable upon exercise of the number of Basic Subscription Rights distributed to you in the Rights Offering, plus the Over -Subscription Privilege, if any. Accordingly, the number of Units that you may purchase in the Rights Offering is limited by the number of shares of our common stock

(including each share of common stock issuable upon exercise of certain outstanding warrants) you held on the Record Date and by the extent to which other stockholders or warrant holders exercise their Basic Subscription Rights and Over -Subscription Privileges, and the extent to which the Existing Rights of First Refusal are exercised, all of which we cannot determine prior to completion of the Rights Offering. However, due to stock exchange restrictions, we will not issue Units in the Rights Offering to the extent that a holder would beneficially own, together with any other person with whom such holder’s securities may be aggregated under applicable law, more than 19.99% of our outstanding shares of common stock.

Subscription Price

The Subscription Price is $1,000 per Unit. The Subscription Price does not necessarily bear any relationship to our past or expected future results of operations, cash flows, current financial condition, or any other established criteria for value. No change will be made to the Subscription Price by reason of changes in the trading price of our common stock or other factor prior to the expiration of this Rights Offering.

Determination of Subscription Price

In the determining the Subscription Price, the board of directors considered a variety of factors including those listed below:

•         our need to raise capital in the near term to continue our operations;

•         the current and historical trading prices of our common stock;

•         a price that would increase the likelihood of participation in the Rights Offering;

•         the cost of capital from other sources;

•         the value of the common stock being issued as a component of the Unit;

•         the value of the Warrant being issued as a component of the Unit; and

•         comparable precedent transactions, including the percentage of shares offered, the terms of the Subscription Rights being offered, the subscription price and the discount that the subscription price represents to the immediately prevailing closing prices for these offerings.

The Subscription Price does not necessarily bear any relationship to any established criteria for value. No valuation consultant or investment banker has opined upon the fairness or adequacy of the Subscription Price. You should not consider the Subscription Price as an indication of actual value of our company or our common stock. The market price of our common stock may decline during or after the Rights Offering. We cannot predict the price at which our shares of common stock will trade after the Rights Offering. You should obtain a current price quote for our common stock and perform an independent assessment of our Warrants before exercising your Subscription Rights and make your own assessment of our business and financial condition, our prospects for the future, and the terms of this Rights Offering. Once made, all exercises of Subscription Rights are irrevocable.

No Short-Sales

By exercising the Subscription Rights, you are representing to us that you have not entered into any short sale or similar transaction with respect to our common stock since the Record Date for the Rights Offering. In addition, the Subscription Rights provide that, upon exercise of the Subscription Right, you represent that you have not since the Record Date and, for so long as you continue to hold Preferred Stock or Warrants issued in connection with the exercise of the Subscription Right, agree to not to enter into any short sale or similar transaction with respect to our common stock. These requirements prevent you from pursuing certain investment strategies that could provide you greater financial benefits than you might have realized if the Subscription Rights did not contain these requirements.

No Recombination

The Preferred Stock and Warrants comprising the Units will separate upon the exercise of the Subscription Rights, and the Units will not trade as a separate security. Holders may not recombine shares of Preferred Stock and Warrants to receive a Unit.

Non-Transferability of Subscription Rights

The Subscription Rights are non -transferable (other than by operation of law) and, therefore, you may not sell, transfer, assign or give away your Subscription Rights to anyone. The Subscription Rights will not be listed for trading on any stock exchange or market.

Expiration Date; Extension

The subscription period, during which you may exercise your Subscription Rights, expires at 5:00 p.m., Eastern Time, on June 25, 2019, which is the expiration of the Rights Offering.

Methods for Exercising Subscription Rights

The exercise of Subscription Rights is irrevocable and may not be cancelled or modified. You may exercise your Subscription Rights as follows:

Subscription by Record Holders

If you are a stockholder or participating warrant holder of record as of the Record Date, the number of Units you may purchase pursuant to your Subscription Rights in indicated on the enclosed Rights Certificate. You may exercise your Subscription Rights by properly completing and executing the Rights Certificate and forwarding it, together with your full payment, to the Subscription Agent at the address given below under “Subscription Agent,” to be received before 5:00 p.m., Eastern Time, on June 25, 2019.

Subscription by Beneficial Owners

If as of the Record Date you are a beneficial owner of shares of our common stock or participating warrants that are registered in the name of a broker, dealer, bank or other nominee, you will not receive a Rights Certificate. Instead, we will issue one Subscription Right to such nominee record holder for all shares of our common stock or participating warrants held by such nominee at the Record Date. If you are not contacted by your nominee, you should promptly contact your nominee in order to subscribe for shares in the Rights Offering and follow the instructions provided by your nominee.

To properly exercise your Over -Subscription Privilege, you must deliver the subscription payment related to your Over -Subscription Privilege before the Rights Offering expires. Because we will not know the total number of unsubscribed Units before the Rights Offering expires, if you wish to maximize the number of shares you purchase pursuant to your Over -Subscription Privilege, you will need to deliver payment in an amount equal to the aggregate subscription payment for the maximum number of Units that you wish to purchase.

Payment Method

Payments must be made in full in U.S. currency by personal check, certified check or bank draft, or by wire transfer, and payable to “Broadridge Corporate Issuer Solutions, Inc., as Subscription Agent for DelMar Pharmaceuticals, Inc.” You must timely pay the full subscription payment, including payment for the Over -Subscription Privilege, for the full number of shares of our common stock you wish to acquire pursuant to the exercise of Subscription Rights by delivering a:

•         certified or personal check drawn against a U.S. bank payable to “Broadridge Corporate Issuer Solutions, Inc. , as Subscription Agent for DelMar Pharmaceuticals, Inc.”;

•         U.S. Postal money order payable to “Broadridge Corporate Issuer Solutions, Inc. , as Subscription Agent for DelMar Pharmaceuticals, Inc.”; or

If you elect to exercise your Subscription Rights, you should consider using a wire transfer or certified check drawn on a U.S. bank to ensure that the Subscription Agent receives your funds before the Rights Offering expires. If you send a personal check, payment will not be deemed to have been received by the Subscription Agent until the check has cleared. The clearinghouse may require five or more business days to clear a personal check. Accordingly, holders who wish to pay the Subscription Price by means of a personal check should make payment sufficiently in advance of the expiration of the Rights Offering to ensure that the payment is received and clears by that date. If you send a certified check, payment will be deemed to have been received by the Subscription Agent immediately upon receipt of such instrument.

You should read the instruction letter accompanying the Rights Certificate carefully and strictly follow it. DO NOT SEND RIGHTS CERTIFICATES OR PAYMENTS DIRECTLY TO US . We will not consider your subscription received until the Subscription Agent has received delivery of a properly completed and duly executed Rights Certificate and payment of the full subscription payment.

The method of delivery of Rights Certificates and payment of the subscription payment to the Subscription Agent will be at the risk of the holders of Subscription Rights. If sent by mail, we recommend that you send those certificates and payments by registered mail, properly insured, with return receipt requested, or by overnight courier, and that you allow a sufficient number of days to ensure delivery to the Subscription Agent and clearance of payment before the Rights Offering expires.

Missing or Incomplete Subscription Forms or Payment

If you fail to complete and sign the Rights Certificate or otherwise fail to follow the subscription procedures that apply to the exercise of your Subscription Rights before the Rights Offering expires, the Subscription Agent will reject your subscription or accept it to the extent of the payment received. Neither we nor our Subscription Agent undertakes any responsibility or action to contact you concerning an incomplete or incorrect subscription form, nor are we under any obligation to correct such forms. We have the sole discretion to determine whether a subscription exercise properly complies with the subscription procedures.

If you send a payment that is insufficient to purchase the number of shares you requested, or if the number of shares you requested is not specified in the forms, the payment received will be applied to exercise your Subscription Rights to the fullest extent possible based on the amount of the payment received. Any excess subscription payments received by the Subscription Agent will be returned, without interest or deduction, within 10 business days following the expiration of the Rights Offering.

Issuance of Preferred Stock and Warrants
