Investing in our common stock involves a high degree of risk. Set forth below are certain material risks and uncertainties known to us that could adversely affect our business, financial condition, or results of operations or could cause our actual results to differ materially from our expectations expressed elsewhere in this Annual Report. The occurrence of the events contemplated by one or more of the factors we describe below could cause the market price of our common stock to decline, resulting in the loss of all or part of any investment in our common stock. Furthermore, other risks that are currently unknown to us or that we currently believe to be immaterial may also, nevertheless, adversely affect our business, financial condition, or results of operations in a way that is material.

Before investing in our common stock, you should carefully consider these risks and uncertainties, together with all other information in this Annual Report, including our consolidated financial statements and related notes, the information included in, Part II — Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations, and the information incorporated herein by reference.

Risks Related to Our Business, Financial Position, Results of Operation, and Organizational Structure

We are engaged in an ongoing strategic review process that could significantly impact our future operations and financial position.

In November 2022, we announced that we are engaged in an ongoing strategic review process with the goal of enhancing shareholder value and have engaged Canaccord as our exclusive financial advisor to assist in this process. Potential strategic alternatives that may be considered as part of this process include an acquisition, merger, reverse merger, other business combinations, sales of assets, licensing or other strategic transactions. There can be no assurance that the exploration of strategic alternatives will result in any agreements or transactions, or that, if completed, any agreements or transactions will be successful or on attractive terms. No timetable has been established for the completion of this process, and we do not expect to disclose developments unless and until the Board has concluded that disclosure is appropriate or required. If we determine to change our business strategy or to seek to engage in a strategic transaction, our future business, prospects, financial position and operating results could be significantly different than those in historical periods or projected by our management. Due to the significant uncertainty regarding our future plans, we are not able to accurately predict the impact of a potential change in our business strategy and future funding requirements as of the date of this Annual Report. Until the review process is concluded, perceived uncertainties related to our future may result in the loss of potential business opportunities, volatility in the market price of our common stock, and may make it more difficult for us to attract and retain qualified personnel and business partners.

The market price of our common stock may decline as a result of our ongoing strategic review process.

The market price of our common stock may decline as a result of our ongoing strategic review process for a number of reasons, including:

There is no assurance that the strategic review process will result in a transaction be completed in a timely manner or at all. If we are unable to consummate a strategic transaction, our business could suffer materially and our stock price could decline.

If our ongoing strategic review process does not result in a transaction being consummated, we may be subject to a number of material risks, and our business and stock price could be adversely affected due to a variety of factors, including:

If we consummate a transaction with a third party in connection with our ongoing strategic review process that involves the issuance of our securities as consideration, the consummation may result in our stockholders having a reduced ownership and voting interest in, and exercising less influence over the management of, the combined organization as compared to their current ownership and voting interests. Nevertheless, our stockholders may not realize a benefit from any such transaction commensurate with the resulting ownership dilution they experience.

If we consummate a transaction with a third party in connection with our ongoing strategic review process that involves the issuance of our securities as consideration, following the closing date of the transaction, our current stockholders would own a smaller percentage of the combined organization than their ownership of Diffusion prior to the Merger. If such a transaction is completed and the combined organization is unable to realize the strategic and financial benefits anticipated therefrom, our stockholders will have experienced substantial dilution of their ownership interests without receiving a commensurate benefit.

Stockholder litigation and regulatory inquiries and investigations are expensive and could harm our business, financial condition and operating results and could divert management attention.

In the past, securities class action litigation and/or stockholder derivative litigation and inquiries or investigations by regulatory authorities have often followed certain significant business transactions, such as the sale of a company or announcement of any other strategic transaction or the announcement of negative events, such as negative results from clinical trials. We are currently and may in the future be the target of this type of litigation as a result of changes in our stock price, past transactions, results of clinical trials or other matters, including any transaction we may pursue or consummate in connection with our ongoing strategic review process. Any stockholder litigation and/or regulatory investigations against us, whether or not resolved in our favor, could result in substantial costs and divert our management’s attention from other business concerns, which could adversely affect our business and cash resources and our ability to consummate a potential strategic transaction or the ultimate value our stockholders receive in any such transaction.

We substantially dependent on our remaining employees to facilitate the consummation of a strategic transaction.

On February 16, 2023, we announced our commitment to a reduction in force impacting six of our 13 employees, including the departure of Dr. Christopher D. Galloway, M.D., our former Chief Medical Officer, and Ms. Raven Jaeger, our former Chief Regulatory Officer, in each case, effective March 1, 2023. Our ability to successfully complete a strategic transaction depends in large part on our ability to retain certain of our remaining personnel. Despite our efforts to retain these employees, one or more may terminate their employment with us on short notice. The loss of the services of any of these employees could potentially harm our ability to consummate a strategic transaction, to run our day-to-day operations, or fulfill our reporting obligations as a public company.

We currently generate no revenue from the sale of products, have incurred significant losses since our inception, have a history of net losses and negative cash flow from operations, expect to incur losses for the foreseeable future, and may never become profitable. In addition, our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations. As a result, any investment in our common stock is speculative and risky.

We are a clinical stage biotechnology company and, as a result, we have a limited operating history from which to assess how we will respond to competitive, economic, or other challenges to our business, and our business and prospects must be considered in light of the risks and uncertainties frequently encountered by similarly situated companies.

We have limited cash resources, have generated substantial net losses and negative cash flow from operations since our inception, and we continue to incur significant research, development, and other expenses related to our ongoing operations. To date, we have not yet obtained regulatory approvals for any of our product candidates and, accordingly, have not generated any revenues from the sale of products. We expect to continue to incur losses and negative cash flow for the foreseeable future. Furthermore, our future operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including the delays in our product development programs including as a result of regulatory review, increased expenditures related to manufacturing or the enforcement of intellectual property rights, other litigation costs, changes in accounting policies, or other unanticipated events.

Our ability to generate sufficient revenues from any of our product candidates, if approved, will depend on numerous factors described throughout this Annual Report. Even if we are able to successfully develop and receive regulatory approval for any of our product candidates, we do not know if or when any such product will achieve commercial success or generate revenue for us, and we will incur significant costs associated with the commercialization that will need to be offset by revenue before achieving a profit. We may also in the future enter into collaboration agreements and license agreements with other companies that include milestone expenditures and payments, in which case our ability to generate revenue or achieve profitability may be dependent on the achievement of those milestones. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods, and our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity. Furthermore, due to the uncertainty of the drug development process, we are often unable to predict the timing or amount of increased expenses, or when we will be able to achieve or maintain profitability, if at all.

If we decide to in-license or acquire one or more additional product candidates or otherwise enter into a strategic transaction, including through our ongoing strategic process, it could impact our liquidity, increase our expenses, and present significant distractions to our management team.

We may, through our ongoing strategic review process or otherwise in the future, implement a strategy to in-license or acquire one or more additional product candidates to supplement our pipeline. We may also consider a variety of other strategic transactions, including spin-offs, partnerships, joint ventures, restructurings, divestitures, business combinations, and minority investments. Any such transaction would expose us to a number of risks and uncertainties, including the potential incurrence of recurring, non-recurring (including unknown liabilities), or other charges (including amortization expenses, write-downs, or other impairment charges), increase of short- and long-term expenditures, or dilution to our stockholders, as well as posing significant integration, implementation, or retention challenges and diverting our management team’s focus on other priorities, including the TSC development program. Any of the foregoing could have a material adverse effect on our business, financial condition, or results of operation. which could adversely affect our operations and financial results. There can be no assurance that we will undertake such a transaction or, if we do, that we will successfully complete the transaction or that the transaction will be additive to our business, financial condition, or results of operations.

In connection with our ongoing strategic review process and pending its conclusion, we have paused significant portions of our TSC development activities. However, if we decide to continue development of TSC or in-license or acquire one or more additional product candidates or otherwise enter into a strategic transaction, including through our ongoing strategic process, we will require additional capital to fund our operations which may not be available on acceptable terms or at all. If we fail to obtain necessary financing, we may be forced to delay or curtail our clinical trials and other development activities or be unable to complete the development and commercialization of our product candidates due to a lack of sufficient resources.

Although we expect that our existing cash resources will enable us to fund our operating expenses and capital expenditure requirements are sufficient to fund its current operations for at least 12 months following the issuance of these financial statements, subject to the outcome of our ongoing strategic review process, we will likely need to obtain additional financing in the future in order to continue our development and operational activities.

We cannot be certain that the additional funding we will require will be available on acceptable terms or at all. Investors may demand significant discounts to market prices or that we agree to restrictive covenants or other limitations on our ability to operate our business, and conditions in the capital markets may make equity and debt financing more difficult to obtain or negatively impact our ability to complete a financing transaction at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back, discontinue the development or commercialization of one or more of our product candidates, or seek alternative financing opportunities such as collaborations or licensing opportunities.

Furthermore, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves the associated risks and uncertainties. Although we have based this estimate on assumptions that we believe to be reasonable, they may prove to be wrong, we could utilize our available capital resources sooner than we currently expect, and actual results could vary greatly from our expectations expressed in this Annual Report as a result. The magnitude and timing of our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

We may need to further increase the size and complexity of our organization in the future including, if any of our product candidates are approved for commercial sale, establishing sales and marketing capabilities. We may experience difficulties in executing our growth strategy or managing any growth that we do experience if we are unable to recruit and retain talented individuals in key positions.

Our ability to succeed in the highly competitive pharmaceuticals industry depends upon our ability to attract and retain highly qualified personnel. As of the date of this Annual Report, we have seven full-time employees and no part-time employees. Our ability to effectively manage our anticipated growth will depend on the outcome and timing of our ongoing strategic review process and multiple other factors, including our ability to:

We are highly dependent on our management and scientific personnel, including our executive officers, certain other key employees and consultants, and the members of our Board. If we lose the services of any of these individuals, we might not be able to find suitable replacements on a timely basis or at all, and our business could be harmed as a result. All of our employees, including our executive officers with whom we have employment agreements, are employed on an at-will basis and their employment can be terminated by us or them at any time. In addition, as part of our reduction in force announced on February 16, 2023, the majority of our clinical operations team was terminated, which would further increase our need to attract additional personnel and/or our reliance on third parties in any future developments efforts.

We may also be unable to attract or retain qualified management and other key personnel in the future due to the intense competition among biotechnology, pharmaceutical, and other businesses. There may be a limited number of persons with the requisite skills to serve in these positions, and we cannot assure you that we will be able to identify or employ qualified personnel for any such position on acceptable terms, if at all, and the high levels of competition within the industry may mean that we will be required to expend significant financial resources in our employee recruitment and retention efforts. Many of the other pharmaceutical companies with whom we compete for qualified personnel have greater financial and other resources, different risk profiles and longer histories in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will harm our ability to implement our business strategy and achieve our business objectives. Furthermore, as we currently have no marketed products, we currently have no sales or marketing personnel or capabilities. To commercialize any our other product candidates, if approved, we will need to build our marketing, sales, distribution, and other related capabilities or arrange with third parties to perform these services, and we may not be successful in doing so.

In addition, we have historically utilized the services of certain outside independent contractors to perform a number of critical functions for our company, including with respect to clinical development, regulatory matters, accounting, and human resources, a practice we expect to continue and may choose to expand in the future. We rely on these independent contractors and effectively managing our relationships with them is and will remain a priority. However, there can be no assurance that we will be able to manage these relationships effectively, that such contractors will be able or choose to continue working with us in the future, or that we will be able to find additional or replacement services if and as needed, on economically reasonable terms or at all.

If we are not able to effectively manage our growth and expand our organization through a combination of effectively retaining our existing employees and third-party contractors and successfully recruiting new employees and contractors, we may be unable to effectively execute on our product development and other strategic plans, which may adversely affect our business, financial condition, or results of operations.

Our ability to utilize our NOL carryforwards and other deferred tax assets may be limited as a result of past and future issuances of our common stock.

As of December 31, 2022, we had $34.2 million in federal and state NOL carryforwards available to reduce future taxable income, if any, for income tax purposes. If not utilized, the NOL carryforwards will begin expiring during the year ending December 31, 2034. Under Section 382 of the Tax Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change, measured by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-ownership change NOL carryforwards and other pre-ownership change tax attributes – such as research tax credits – to offset its post-ownership change income may be limited.

General Risks Related to Our Business, Financial Condition, Results of Operations, and Organizational Structure

Our business, financial condition, or results of operations may also be materially adversely affected by a number of general risks related thereto and to our organizational structure that are not specific to our Company, including:

•    If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. Furthermore, our disclosure controls and procedures are subject to inherent limitations, human error, and other systematic breakdowns, and therefore may not prevent or detect all errors or acts of fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which could harm our business, financial condition, or results of operations.

•    As our Company, the industry in which we operate, and the world-at-large become increasingly virtual, our acquisition and implementation of additional information technology solutions and our compliance with global privacy and data security requirements could result in additional costs and liabilities or inhibit our ability to collect and process data globally. Furthermore, any failure to comply with applicable requirements or best practices – as well as other events outside of our control – could result in a security breach or other disruption to our information technology systems, limit our capacity to effectively monitor and control our operations, compromise our or third parties’ confidential information, or otherwise adversely affect our business, financial condition, or results of operations.

•    We incur significant costs as a result of our public company status and devote substantial management time to operating as a public company, including complying with the applicable requirements of the Securities Act, the Exchange Act, the Dodd-Frank Act, SOX, and the rules and regulations of Nasdaq. If, in the future, we are required to include in our annual report an attestation of our independent registered public accounting firm regarding internal control over financial reporting, the amount of these compliance costs would increase significantly.

•    Although we have in place business continuity and disaster recovery plans, our business, financial condition, or results of operations could be negatively affected by volatility, disruptions, or other uncertainty caused by market fluctuations, economic downturns or unfavorable global economic conditions, pandemics, natural disasters or other catastrophic events, events of war, terrorism, or other man-made problems, or other geopolitical events outside of our control, such as the ongoing war in Ukraine, the COVID-19 pandemic and Brexit.

•    If we fail to comply with applicable laws and regulations, including the healthcare laws and regulations described under the heading, Part I – Item 1. Business – Certain Other Legislation and Regulations – Current Healthcare Laws and Regulations and applicable environmental, health, and safety laws and regulations, we could become subject to fines, penalties, or other consequences.

Risks Related to Ownership of Our Common Stock

Our stock price is volatile and any investment in our securities may suffer a decline in value, including as a result of our ongoing strategic review process. In addition, this volatility may subject our business to additional risks, such as an increased risk of securities litigation.

During the year ended December 31, 2022, the closing market price for our common stock as reported by Nasdaq varied between a high of $16.95 on March 23, 2022 and a low of $4.64 on November 10, 2022. As a result of fluctuations in the price of our common stock, you may be unable to sell shares or our common stock at or above the price you paid for them, even if your holding period is relatively short. The market price of our common stock is likely to continue to be volatile and subject to significant price and volume fluctuations in response to the outcome of our strategic review process and market, industry and other factors, including the degree of analyst coverage of our stock, their valuations and recommendations, and whether any such analysts publish inaccurate or unfavorable research about our business. If the results of our business do not meet these analysts’ forecasts, the expectations of investors or the financial guidance we provide to investors in any period, the market price of our common stock could decline. Furthermore, despite this volatility, due to the fact that we have never declared or paid cash dividends on our common stock and do not currently anticipate declaring or paying any cash dividends in the foreseeable future, we expect that only appreciation of the price of our common stock, if any, will provide a return to our stockholders for the foreseeable future.

Historically, the stock markets in general, and the markets for biotechnology stocks in particular, have experienced significant volatility that has at times been unrelated to the financial condition or results of operations of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock and, consequently, adversely affect the price at which you are able to sell any shares of our common stock that you own. In the past, following periods of volatility in the market or significant price declines in individual securities or the market as a whole, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.

We have funded our operations to date through the issuance of securities, including common stock, warrants to purchase common stock, convertible preferred stock, and convertible debt securities, and we expect that in the future we will need to raise additional capital through similar means to fund our continued operations and liquidity needs. Assuming funding is available on acceptable terms, any future issuance of common stock or securities convertible for or exchangeable into common stock – including any stock issued to fund an acquisition, in connection with our strategic review process or otherwise, will result in dilution to our existing stockholders and could depress the market price of our common stock. Furthermore, the terms of future financing transactions may contain provisions that restrict our operations or require us to relinquish certain rights to our product candidates or other technologies.

Subject to the outcome of our strategic review process, we will likely need to raise additional funds in the future to continue our operations, fund research and development, and, if approved, commercialize our product candidates. We plan to continue to finance our operations with a combination of equity issuances, debt arrangements, and, potentially, licensing, or other partnering relationships. Our Board may determine at any time to raise additional capital if it believes the terms are in the best interests of our stockholders. In addition, we may also issue securities to counterparties as part of an acquisition, merger, or similar transaction, including as part of our strategic review process.

Accordingly, new issuances of a substantial number of shares of our common stock could occur at any time. Any issuance or sale of shares, or the perception in the market of an intent to issue or sell shares in the near-term, by the Company or holders of a large number of shares could reduce the market price of our common stock. We also cannot assure you that any such sale of common stock or other securities will be at a price per share that is equal to or greater than the price per share paid by you for our common stock. Furthermore, a depressed stock price could limit our ability to raise necessary capital through the sale of additional equity securities on terms that are acceptable.

We may also seek additional capital through other methods, either alone or in combination with the issuance of additional securities, including debt financings, receivables or royalty financings, strategic partnerships and alliances, and licensing arrangements, any of which could be coupled with an equity component, such as warrants to purchase stock. The incurrence of indebtedness could result in increased fixed payment obligations, liens and other security interests being placed on certain of our assets, and certain restrictive covenants being imposed on the operation of our business, such as limitations on our ability to incur additional debt or acquire intellectual property rights. We may also in the future raise additional funds through strategic partnerships, alliances, and licensing arrangements with third parties, any of which could require us to relinquish valuable rights to our product candidates or other assets. The restrictions imposed by any of these arrangements could materially decrease any potential returns on our investment in our product candidates, or otherwise materially and adversely affect our business, financial condition, or results of operations.

Our organizational documents impose certain anti-takeover provisions and make the Delaware Chancery Court the exclusive forum for certain stockholder actions, which could depress the trading price of our common stock.

Our certificate of incorporation, as amended, and our Bylaws contain provisions that may make the acquisition of our company, a proxy contest, or the nomination of a director candidate by a stockholder more difficult than such actions would be in the absence of such provisions, including that:

In addition our Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the sole and exclusive forum for certain actions, including derivative actions brought on the Company's behalf, stockholder actions claiming breaches of a fiduciary duty owed by any of our directors or officers, and claims arising under our organizational documents, in each case, subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Although this provision would not apply to any stockholder claims under the Exchange Act, there is uncertainty regarding whether a court would enforce such a forum selection provision as written to stockholder claims under the Securities Act. Nevertheless, this forum selection provision may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or agents, which may discourage lawsuits against us and such persons. The limitations on certain stockholder rights imposed by these provisions could also depress the trading price of our common stock.

If we cannot continue to satisfy the NASDAQ Capital Market continued listing standards and other NASDAQ rules, our Common Stock could be delisted, which would harm our business, the trading price of our Common Stock, our ability to raise additional capital and the liquidity of the market for our Common Stock.

Our common stock is currently listed on the NASDAQ Capital Market. To maintain the listing of our common stock on the NASDAQ Capital Market, we are required to meet certain listing requirements. In the event that our common stock is delisted from NASDAQ and is not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult for us to raise capital and for our stockholders to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further.

Risks Related to Our Intellectual Property

In connection with our ongoing strategic review process and pending its conclusion, we have paused significant portions of our TSC development activities. If we choose to pursue further development of TSC or any other product candidate, we may not be able to obtain or enforce patent rights or other intellectual property rights that cover our product candidates and technologies that are of sufficient breadth to prevent third parties from competing against us.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition, and a strong emphasis on developing proprietary therapeutics. Numerous companies are engaged in the development, patenting, manufacturing, and marketing of health care products competitive with those that we are developing, and we face competition from a number of sources, such as pharmaceutical companies, generic drug companies, biotechnology companies and academic and research institutions. Accordingly, our ability to obtain and maintain patent protection in both the U.S. and non-U.S. jurisdictions will be critical to our ability to successfully develop, obtain regulatory approval for, and, in particular, commercialize TSC and our other product candidates. These protections are and will be essential to preserving and protecting our novel inventions, proprietary developments, and trade secrets and to preventing third parties from infringing upon them. In particular, our ability to protect any of our product candidates from unauthorized or infringing use by third parties depends in substantial part on our ability to obtain and maintain valid and enforceable patents in the U.S. and worldwide.

Our patent portfolio includes patents and patent applications in the U.S. and other major markets covering our technology with varying scope, including issued U.S. patents related to composition of matter, formulation, methods of delivery, and methods of use and the scope of coverage vary from country to country. Although we believe that our intellectual property position is strong and are currently assessing our operations and existing portfolio for additional intellectual property opportunities, we do not have – and may be unable to obtain – patent protection for every aspect of our technology. For aspects of our technology for which we do not have patent coverage, or in countries where we do not have granted patents, we may not have any ability to prevent the unauthorized use of our technologies or technologies substantially similar to ours, and any patents that we may obtain in the future may be narrow in scope and thus easily circumvented by competitors. Further, in countries where we do not have granted patents, third parties may be able to make, use or sell products identical to or substantially similar to, our product candidates.

Due to legal standards relating to patentability, validity, enforceability and claim scope of patents covering pharmaceutical inventions, our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. The patent application process, also known as patent prosecution, is expensive and time-consuming, and we may not be able to prepare, file, and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Despite any past and future efforts to obtain additional intellectual property and patent protections for product candidates, there is no assurance we will obtain such protections through our applications. Therefore, these and any of our patents and applications may not be prosecuted and enforced in an optimal manner. It is also possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, such as with respect to inadvertent prior public disclosures, proper priority claims, inventorship, claim scope, or patent term adjustments. If our current or future third party development partners are not fully cooperative or disagree with us as to the prosecution, maintenance, or enforcement of any patent rights, those patent rights could be compromised and we might not be able to prevent third parties from making, using and selling competing products. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. Accordingly, we cannot guarantee that any patents will issue from any of our currently pending patent applications, which could impair our ability to prevent competition from third parties.

Even for aspects of our technology for which we have obtained, or obtain in the future, patent protection, the complexity of legal and factual questions underlying such claims means they may not provide us with sufficient protection for our product candidates to afford a commercial advantage against competitive products or processes, including those from branded and generic pharmaceutical companies. We cannot guarantee that the claims of these patents are or will be held valid or enforceable by the courts or will provide us with any significant protection against competitive products or otherwise be commercially valuable to us. Third parties may design around or challenge the validity, enforceability or scope of such issued patents or any other issued patents we own or license, which may result in such patents being narrowed, invalidated or held unenforceable. If the breadth or strength of protection provided by the patents we hold or pursue with respect to our product candidates is challenged, it could dissuade companies from collaborating with us to develop, or threaten our ability to commercialize, our product candidates. Changes in either the patent laws or in the interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property.

In addition, patents have a limited lifespan, presenting further challenges in effectively protecting our technologies and associated commercial position. In the U.S., the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available under a variety of legislative and regulatory avenues but often the life afforded by these extensions and the protections they afford are limited relative to full patent protection. The extensive period of time between patent filing and regulatory approval for a product candidate limits the time during which we can market a product candidate under patent protection, which may particularly affect the profitability of our early-stage product candidates. Even if patents covering our products are obtained, once the patent life has expired, we may be open to competition from competitive products. If one of our products requires extended development, testing and/or regulatory review, patents protecting such products might expire before or shortly after such products 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, which could have a material adverse effect on our business, financial condition and results of operations.

For example, historically, our primary focus since the founding of Diffusion LLC in the early 2000s has been developing TSC and, as a result, portions of our patent portfolio, including certain patents related to TSC’s composition of matter, have expired or will expire in the near future. While the Company actively engages in efforts to obtain additional patent protection covering our product candidates, there is no assurance that we will successfully obtain such patent protection.. Furthermore, if we are unable to obtain regulatory approval of and successfully commercialize our product candidates prior to the expirations of key underlying patents, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Furthermore, the laws of some foreign jurisdictions do not provide intellectual property rights to the same extent as in the United States and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally in those countries. If we encounter such difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property in foreign jurisdictions, our business prospects could be substantially harmed.

Proprietary trade secrets and unpatented know-how are also very important to our business. Although we have taken steps to protect our trade secrets and unpatented know-how by entering into confidentiality agreements with third parties, and intellectual property protection agreements with certain employees, consultants and advisors, third parties may still obtain this information or we may be unable to protect our rights. We also have limited control over the protection of trade secrets used by our suppliers, manufacturers and other third parties. There can be no assurance that binding agreements will not be breached, that we would have adequate remedies for any breach or that our trade secrets and unpatented know-how will not otherwise become known or be independently discovered by our competitors. If trade secrets are independently discovered, we would not be able to prevent their use. Enforcing a claim that a third party illegally obtained and is using our trade secrets or unpatented know-how is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the U.S. may be less willing to protect trade secret information.

If we are unable to adequately obtain or enforce our patent and other intellectual property rights for any reason, it could materially and adversely affect our business, financial condition, and results of operations. For more information about our intellectual property and our competition, see the information included under the heading, “Part I – Item 1. Business – Products, Product Development, and Our Competition – Our Intellectual Property” and “— Our Competition.”

If we become involved in lawsuits to protect or enforce our patents or other intellectual property, or if we are sued for infringing intellectual property rights of third parties, it will be costly and time-consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business, financial condition, or results of operations.

Our ultimate commercial success depends upon our ability to develop, manufacture, market, and sell our product candidates and use our proprietary technologies in the U.S. and non-U.S. markets. In order to do so, it is critical that we prevent third parties from infringing on our intellectual property rights and that we operate our business without infringing on the intellectual property rights of others.

However, numerous U.S. and non-U.S. issued patents and pending patent applications owned by third parties exist in fields relating to our product candidates, their potential methods of delivery, potential indications they may be used to treat, and their other features, and, as more patents are issued over time, the risk increases that others may assert that our product candidates, technologies, or methods of delivery or use infringe their patent or other intellectual property rights, or that we discover a third party infringing on our rights. Moreover, it is not always clear to industry participants, including us, which patents cover various drugs, biologics, drug delivery systems, or their methods of use, which of these patents may be valid and enforceable, and what inventions or technologies may be claimed by non-public patent applications. Patent applications in the U.S. and many foreign jurisdictions are typically not published until 18 months after their first non-provisional filing and publications in the scientific literature often lag behind actual discoveries, meaning we cannot be certain whether others, including our competitors, have filed patent applications for technology covered by patents or our pending applications and whether any such filing has priority over our own applications or patents.

In the biopharmaceutical and pharmaceutical industries in particular, there is a substantial amount of litigation involving patent and other intellectual property rights. This type of litigation may occur unexpectedly but may also be prompted by specific events, such as a patent application being made public by the USPTO or a non-U.S. governmental authority or under Paragraph IV of the Hatch-Waxman Amendments. For more information regarding the Hatch-Waxman Amendments and Paragraph IV thereunder, see the information included under the heading, “Part I – Item 1. Business – Government Regulation – The Hatch-Waxman Amendments.”

As of the date of this Annual Report, no litigation asserting infringement claims has been brought against us, nor have we filed such a claim against any third party. However, we cannot assure you that the development or future commercialization of any of our product candidates or other technologies will not result in claims that our activities infringe on the existing or future intellectual property rights of third parties. Furthermore, potential competitors may infringe our intellectual property, including our patents.

We may be required to file infringement claims to stop third-party infringement or unauthorized use or, if a third party claims we are infringing on their rights, respond to such claims. This process can be expensive and time consuming, and could result in a court deciding that a patent of ours is not valid or is unenforceable, that a third party is not required to stop using a technology we believe infringes on our rights, significant costs, or the diversion of management’s time. An adverse determination in any litigation or other proceedings could put one or more of our patents at risk of being invalidated, interpreted narrowly, or amended such that they do not cover our product candidates in a manner sufficient to support our development and commercialization needs or that such product candidate needs to be significantly redesigned, or put our pending patent applications at risk of not issuing, or issuing with limited and potentially inadequate scope. Further, some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources.

In addition, interference, derivation, or other proceedings brought at the USPTO may be necessary to determine the priority or patentability of inventions with respect to our patents or patent applications. Litigation or USPTO proceedings brought by us may fail or may be invoked against us by third parties. Even if we are successful in these proceedings, domestic or foreign litigation or USPTO or foreign patent office proceedings may result in substantial costs and the diversion of management’s time. We may not be able to prevent all misappropriation of our proprietary rights, particularly in countries with a legal framework that offers limited intellectual property protections or where the costs of enforcement outweigh the commercial and other benefits of maintaining intellectual property protections.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other proceedings, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings, including as a result of public announcements of the results of hearings, motions or other interim proceedings or developments, or public access to related documents. This type of disclosure could put us at a significant competitive disadvantage by disclosing important trade secrets or other proprietary information to our competitors and other third parties.

Any litigation or other challenge related to our intellectual property could materially and adversely affect our business, financial condition, and results of operations.

General Risks Related to Our Intellectual Property

Our business, financial condition, or results of operations may also be materially adversely affected by a number of general risks related to our intellectual property that are not specific to our Company, including:

•    As is common in the biopharmaceutical and pharmaceutical industries, some of our employees were formerly employed by companies in the industry, including our competitors or potential competitors, and some of our consultants actively work for other companies in the industry. As a result, although we have in place policies which prohibit the use of third-party confidential information in violation of any obligation to a former employer or otherwise, we may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed to us alleged trade secrets of their former employers or their former or current customers. In addition, if any of our current employees or consultants are engaged by a competitor in the future, it is possible that they may appropriate or otherwise improperly use our proprietary and confidential information. Any of the foregoing events could result in significant costs and the diversion of time and resources.

•    Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated as a result of any non-compliance with these requirements. We may also abandon certain intellectual property protections that we would otherwise maintain if we determine such protections are not expected to provide sufficient value relative to the cost of ongoing maintenance.

•    Patent laws and other intellectual property protections available in the U.S., E.U., or other jurisdictions are subject to change. These changes may be unpredictable, weaken our overall intellectual property position, increase our costs related to maintenance and enforcement, or otherwise diminish the value of patents in general, thereby impairing our ability to protect our product candidates and maximize our return on investment thereon.

Risks Related to the Development, Regulatory Approval, and Commercialization of Our Product Candidates

The success of Diffusion is dependent on the successful development, regulatory approval, and, ultimately, commercialization of our product candidates. However, the drug development process is expensive, time-consuming and uncertain. Our efforts to develop, obtain regulatory approval for, and commercialize any of our product candidates could fail at any stage of the development process for a variety of reasons. Furthermore, because the results of preclinical studies and early-stage clinical trials are not necessarily predictive of future results, even if we are able to advance a product candidate into additional clinical trials, we may not continue to experience favorable results.

The success of Diffusion, including our ability to finance our operations and generate revenue in the future, will depend primarily on the successful development, regulatory approval, and, ultimately, commercialization of our product candidates. Historically, the majority of our product development resources have been dedicated to our most advanced product candidate, TSC, and for the foreseeable future, our planned expenditures are primarily related to our ongoing strategic review process and other costs associated with the conduct of certain preclinical studies and general research and development activities related to TSC. In the future, we may also seek to develop or commercialize additional product candidates, including product candidates that we may in-license or acquire to supplement our internally developed portfolio through our ongoing strategic process or otherwise.

The drug development process is very expensive, time-consuming, difficult to design and implement, and its outcome is inherently uncertain. Most product candidates that commence clinical trials are never approved by regulatory authorities for commercialization and success in early-stage clinical trials does not ensure that later clinical trials will demonstrate the efficacy and safety of an investigational drug in a manner adequate to support regulatory approval. Countless other companies, including many with greater resources and experience, have failed or suffered significant setbacks attempting to navigate the drug development process, and there can be no assurance that we will have success where others have failed.

Our current product candidates remain in early stages of the development process and, if further developed, we expect that the additional clinical trials necessary to support an NDA will take several years to complete. We do not know whether the clinical trials we may conduct will demonstrate adequate efficacy and safety or otherwise provide adequate information to result in regulatory approval to market any of our product candidates in any particular jurisdiction. Furthermore, the timeline for our clinical trials may be delayed in the future for a variety of reasons, including delays related to regulatory and IRB review and approval, slower than anticipated rates of enrollment in or early withdrawals from the trial, third party performance issues beyond our control including any CRO engaged in the conduct of the trial, discovery of series or unexpected toxicities or side effects, or a lack of effectiveness.

Whether we are able to successfully develop any of our product candidates will depend on a large number of factors, including the following:

Any of these factors, many of which are beyond our control, could result in significant delays or an inability to develop, obtain regulatory approvals for, or commercialize our product candidates, and we may ultimately be able to receive regulatory approval or generate revenue from the sale of any product candidate.

A number of companies in the pharmaceutical and biopharmaceutical industry have suffered significant setbacks in later-stage Phase 3 clinical development even after promising results in earlier preclinical studies or clinical trials. If later-stage clinical trials do not produce favorable results for our product candidates, or we are unable to complete the necessary clinical trials for any reason (including a lack of funding), our ability to achieve regulatory approval or successfully commercialize may be compromised. At any time, we may decide or be forced by circumstance to delay or discontinue the development or commercialization of TSC or any of our other product candidates, including as a result of unfavorable results in later-stage clinical trials, changes in our internal product, technology or indication focus, the appearance of new technologies that make our product candidate obsolete, competition from a competing product, or changes in (or failure to comply with) applicable regulatory requirements. If we decide or are forced to terminate any development program in which we have invested significant resources, we may not receive any return on our investment despite the allocation of significant resources, we may not be able to execute on our business plan effectively, and our business, financial condition, results of operations may be materially and adversely affected.

Even if we are able to successfully complete the clinical trials and over development activities necessary to submit an NDA to the FDA or an application for marketing approval to an equivalent non-U.S. regulatory authority, we may be unable to obtain regulatory approval for any product candidates we may attempt to develop, for the indications for which we initially seek approval or at all. The FDA and similar non-U.S. regulatory authorities have significant discretion in the approval process, including the ability to delay, limit, or deny approval of product candidates. The delay, limitation, or denial of regulatory approval for any of our product candidates would limit or restrict altogether our ability to commercialize the product and generate revenue, which could materially and adversely impact our business, financial condition, and results of operations.

We currently have no products approved for sale, and we may never obtain regulatory approval to commercialize any product candidates we may attempt to develop. The research, testing, manufacturing, safety surveillance, efficacy, quality control, recordkeeping, labeling, packaging, storage, approval, sale, marketing, distribution, import, export, and reporting of safety and other post-market information related to drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States and abroad, which often differ from country to country. We will not be permitted to market any of our product candidates in the U.S. until we receive approval of an NDA or other applicable regulatory filing from the FDA, and we will not be permitted to market in any non-U.S. countries until we receive the requisite approval from the applicable regulatory authorities.

To gain approval to market a new drug, the FDA and similar non-U.S. regulatory authorities require the submission of an NDA (or similar application) that contains preclinical and clinical data adequately demonstrating the safety, purity, potency, efficacy, and compliant manufacturing of the product for the intended indication. The FDA and their non-U.S. counterparts have substantial discretion in the drug approval process, including the ability to delay, limit, or deny approval of applications for many reasons, including:

Historically, of the large number of drugs in development at any given time, only a small percentage successfully complete the regulatory approval processes and are ultimately commercialized. Our product candidates may not be approved for sale and marketing by the FDA or any other governmental authority, even if they meet specified endpoints in our clinical trials. The FDA or applicable foreign regulatory agencies may ask us to conduct additional costly and time-consuming clinical trials in order to obtain marketing approval or approval to enter into a further phase of clinical development, or may change the requirements for approval even after such agency has reviewed and commented on the design for the clinical trials.

Any delay in obtaining, or inability to obtain, the regulatory approvals necessary to market and sell our product candidates would delay or prevent commercialization and would materially and adversely affect our business, financial condition, and result of operations. Furthermore, if we determine in the future that the development, approval, or commercial prospects of any product candidate are insufficient to justify our continued expenditure of the associated development and other costs, we may choose to delay, suspend, or abandon our development or commercialization efforts with respect thereto, which would reduce or eliminate our potential return on investment for those product candidates.

Our ability to develop our product candidates depends, and, if any of our product candidates are approved, our ability to successfully commercialize our products will depend, in part on our ability to successfully obtain sufficient quantities of the necessary APIs, other component substances and materials, and finished drug product for our product candidates. We are currently entirely dependent on third parties for the manufacture and supply of our product candidates and their component parts, including, with respect to our product candidate TSC, a sole supplier. We may be unable to continue to develop or commercialize our product candidates or face significant delays in that process if we are unable to successfully obtain these materials or manufacture drug product in sufficient quantities.

Maintaining an adequate supply of our product candidates to meet our needs is critical to the success of our business. However, manufacturing and supply of APIs, other substances and materials and finished drug products is a complex and technically challenging process, and changes beyond our direct control can impact the quality, volume, price, and successful delivery of our product candidates or impede, delay, limit or prevent the successful development and commercialization of our product candidates. Mistakes and mishandling are not uncommon in the biopharmaceutical and pharmaceutical industry and can affect successful production and supply significantly.

As of the date of this Annual Report, we have no internal manufacturing capabilities and therefore we do not have direct control over our ability to maintain drug supply sufficient to serve our needs for our ongoing and planned clinical trials or, if any of our product candidates are approved, commercialization. Although we are ultimately responsible for ensuring compliance with regulatory requirements such as cGMPs, we are dependent on our third party CMOs and other contract suppliers and manufacturers for the manufacture of our drug product, including both APIs and finished products, as well as day-to-day compliance with cGMPs and certain other manufacturing-related regulatory requirements. Facilities used by our contract suppliers and manufacturers to produce the APIs and other substances and materials or finished products for commercial sale must pass inspection, provide regulators with certain technical information, and be approved by the FDA and other relevant regulatory authorities to confirm compliance with cGMP requirements and other regulatory requirements. If the safety of TSC or any of our other product candidates (or any component thereof) is found in the future to be compromised, we may not be able to successfully commercialize or obtain regulatory approval for the product candidate, and we may be held liable for injuries sustained as a result.

Any disruption in our relationship with these third parties or their ability to manufacture the APIs and finished drug product we need for our clinical trials and other development activities could result in significant delays in our anticipated development timelines and/or significant additional supply costs. Such a disruption could be the result of any number of reasons, including contractual disputes with our partners, regulatory issues with our partners or at their facilities (whether or not related to Diffusion or our drug product), financial issues faced by our partners (including bankruptcy or insolvency), damages to our partners’ facilities or equipment, communication breakdowns, or acts of God. For example, during 2021 we faced certain delays in the manufacturing process for planned, new batches of TSC drug product due to the fact that, in connection with the U.S. federal government’s Operation Warp Speed initiative in response to the COVID-19 pandemic, the facility at which our former, primary CMO partner conducts significant portions of the TSC manufacturing process had been mandated to devote the majority of the facility’s available resources to the manufacture of components of the COVID-19 vaccine.

Amplifying this risk is the fact that, notwithstanding the improvements made to our supply chain during 2021 described under, "Business - Product Development - Chemistry, Manufacturing, and Controls," we currently depend upon a sole source to manufacture our API for TSC and other aspects of our manufacturing process, limiting our available options to troubleshoot these issues. Although we actively manage this third-party relationship to ensure continuity, quality, and compliance with regulations and we intend to identify and develop alternative manufacturing and supply alternatives in the future, this process remains ongoing, will take time, and will involve significant costs. Even with these efforts, some events beyond our control, including global instability due to political unrest or from an outbreak of pandemic or contagious disease, such as COVID-19, could result in supply chain disruptions or the complete or partial failure of these manufacturing services. Any such failure or disruptions could materially adversely affect our business, financial condition, cash flows, and results of operations. Furthermore, due to the significant regulatory oversight of the pharmaceutical manufacturing process, any changes in the identity of our third-party partners or in our manufacturing processes – even if in the best interests of the Company and successful – could result in regulatory and other delays, as well as significant additional costs. In addition, if our current supplier terminated our arrangement or failed to meet our supply needs for any reason prior to the time we are able to identify sufficient alternative manufacturing capacity, we may be forced to delay our development plans significantly.

Our CMO and other manufacturing and supply partners are also engaged to supply and manufacture materials or products for other biopharmaceutical and pharmaceutical companies, exposing them to regulatory risks unrelated to the work they are doing for Diffusion but which may nevertheless impact their ability to meet their contractual requirements to us or otherwise impede their ability to supply us with sufficient quantities of drug product. Failure to meet the regulatory requirements for the production of those materials and products may also affect the regulatory clearance of a contract supplier’s or manufacturer’s facility. If the FDA or a comparable foreign regulatory agency does not approve these facilities for the supply or manufacture of our product candidates or if it withdraws its approval in the future, even if such lack of approval is unrelated to Diffusion or our product candidates, we may need to find alternative supply or manufacturing facilities.

In addition, to date we have only manufactured TSC and our other product candidates in relatively small quantities for preclinical studies and clinical trials. As we prepare for additional, later-stage clinical trials and potential commercialization, we will need to take steps to substantially increase the scale at which we are able to produce TSC, its API, and its other component parts. In order to meet these needs, our CMOs and suppliers will need to produce our API, other components, and finished product in larger quantities, more cost effectively and, in certain cases, at higher yields than they currently achieve. These third-party contractors may not be able to successfully increase the manufacturing capacity for any of such drug substance and product candidates in a timely or cost-effective manner or at all. Even if such a scale up is possible, it may require additional processes, technologies, and validation studies, which are costly, may not be successful, and which the FDA and foreign regulatory authorities would need to review and approve prior to any commercial sale of TSC or any other product candidate. In addition, quality issues may arise during those scale-up activities because of the inherent properties of a product candidate itself or in combination with other components added during the process of manufacturing, packaging, shipping, or storage.

Our reliance on contract manufacturers and suppliers further exposes us to the possibility that they, or third parties with access to their facilities, will have access to and may misappropriate our trade secrets or other proprietary information. In addition, the manufacturing facilities of certain of our suppliers are located outside of the United States. This may give rise to difficulties in importing our product candidates or their components into the United States or other countries as a result of, among other things, regulatory agency approval requirements or import inspections, incomplete or inaccurate import documentation or defective packaging.

Any of these factors could cause a delay or termination of preclinical studies, clinical trials, other development activities, regulatory submissions or approvals of our product candidates, or, if any of our product candidates is approved, commercial supply, and could result in significant, unanticipated costs or an inability to effectively develop our products candidates or commercialize our approved products on a timely basis, or at all, which could materially and adversely affect our business, financial condition, and results of operations.

We expect to rely on third-party CROs and other third parties to conduct and oversee our clinical trials and other aspects of our development process for our product candidates. If these third parties do not meet our requirements or otherwise conduct the trials or perform the other services for which they are engaged, we may not be able to successfully develop, obtain regulatory approval for, or commercialize our product candidates when expected or at all. Furthermore, if we are not able to establish and maintain the necessary collaborative relationships with our CROs and other third party partners, we may have to alter our development and commercialization plans.

Conducting our clinical trials in a safe, compliant, and timely manner is critical to our success. We have historically relied on third-party CROs to conduct and oversee our clinical trials and other aspects of our product development, as well as various medical institutions, clinical investigators, contract laboratories, consultants, and other third parties to design and conduct our trials, to analyze the results therefrom, and to ensure that the trials are conducted in accordance with our clinical protocols and all applicable regulatory requirements, including the FDA’s regulations and GCPs. These CROs and other third parties play a significant role in the conduct of these trials and the subsequent collection and analysis of data therefrom, as we control only certain aspects of their activities and rely heavily on them to execute our trials in a safe, compliant, and timely manner. Although we may internalize portions of  these functions if and as our organization grows, we expect to continue to rely on these third parties to a significant degree in the future.

If any of our CROs, clinical trial sites, or other third party partners terminates their involvement in one of our clinical trials (or with Diffusion entirely) for any reason, we may not be able to enter into alternative arrangements sufficient to meet our needs, on a timely basis, on commercially reasonable terms, or at all. In addition, if our relationship with clinical trial sites is terminated, we may incur significant additional costs or experience the loss of follow-up information on patients enrolled in our ongoing clinical trials, unless we are able to transfer the care of those patients to another qualified clinical trial site.

We, as well as the CROs and other third-party contractors acting on our behalf, are required to comply with GCP and GLP requirements in all of our clinical trials, which are enforced through periodic inspections of trial sponsors, principal investigators, and trial sites. If we or any of these third parties fail to comply with applicable GCP, GLP, or other regulatory requirements, the clinical data generated in our clinical trials may be deemed unreliable and we may be required to perform additional clinical trials to supplement or replace such data before receiving approval of a product candidate from the FDA foreign regulatory authority. Our clinical trials must also generally be conducted with product produced under cGMP regulations. Our and our partners’ compliance with these various regulations may be reviewed by regulatory inspections at any time, processes over which we will have very little control or immediate visibility, and a failure to comply with these regulations and policies by us, our CROs, or any of our other third party partners may result in significant delays in our development programs. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and could receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be questioned by the FDA.

In addition, in order to fund or otherwise further development of our current or future product candidates, we may collaborate with other pharmaceutical and biotechnology companies on their development and potential commercialization of those product candidates. We would face significant competition in seeking appropriate partners and whether we reach a definitive agreement for a collaboration will depend on many factors, including, our assessment of a partner’s resources and experience, the terms and conditions of the proposed collaboration, the likelihood of approval by the FDA or other regulatory authorities; the potential market for the subject product candidate; uncertainty with respect to our ownership of our intellectual property; and industry and market conditions generally. These types of collaborations are complex and time-consuming to negotiate and document and could ultimately result in lower returns on investment for our stockholders than would have been achieved developing the product candidate without a partner. Further, if we were to breach our obligations under the agreements governing any such future collaboration, we may face substantial consequences, including potential termination of the collaboration, and our rights to our partners’ product candidates, in which we have invested substantial time and money, would be lost.

Any failure to successfully enter into and maintain the necessary relationships with CROs and our other current and future third party partners and collaborators could materially and adversely affect our business, financial condition, and results of operations.

General Risks Related to the Development, Regulatory Approval, and Commercialization of Our Product Candidates

Our business, financial condition, or results of operations may also be materially adversely affected by a number of general risks related to the development and regulatory approval of our product candidates that are not specific to our Company, including:

•    Our COVID Trial, which we completed in February 2021, was conducted in Bucharest, Romania and we may in the future conduct additional clinical trials for TSC or our other product candidates outside the U.S. In connection with an application for marketing approval, the FDA may determine not to accept data from clinical trials conducted outside of the U.S. if they determine the data presented therefrom cannot be considered valid without further inspection of the clinical trial site, are not applicable to the U.S. population and U.S. medical practice, or as a result of certain other factors. There can be no assurance that the FDA will accept any data we obtain from trials we have conducted or may in the future conduct outside the U.S.

•    We face a number of risks related to the potential for one or more of our future product candidates to cause undesirable side effects, have other unexpected properties, contain manufacturing defects, or be subject to misuse or abuse. The occurrence of one or more of these events with respect to a product candidate or product could delay or prevent its regulatory approval, limit its commercial potential, result in additional pre- or post-approval regulatory requirements, or subject us to product liability exposure to consumers, health care providers, or others. Product liability claims could be brought in the future even if a product candidate is ultimately approved for commercial sale and manufactured in facilities licensed and regulated by the appropriate governmental authorities, and if product liability claims brought against us in the future were to be successful, we could incur substantial liability if our insurance coverage for those claims proved to be inadequate.

•    Our employees, independent contractors, principal investigators, consultants, vendors, CROs, and other third parties we work with in the course of our development activities may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, during the course of their employment or other engagement with us. Any such misconduct or improper activities, whether intentional or negligent, could result in regulatory sanctions or other penalties against the Company, exclusion from federal healthcare programs such as Medicare and Medicaid, the incurrence of substantial defense costs, and serious harm to our reputation.

In addition, although we currently have no marketed products, in the event any of our product candidates are approved for marketing and commercial sale by the FDA or any other regulatory authority, our business, financial condition, or results of operations may be materially adversely affected by a number of general risks related to the commercialization of such products that are not specific to our Company, including:

•    Even if our product candidates obtain regulatory approval, they may fail to achieve the broad degree of physician and patient adoption and use necessary for commercial success. The degree and rate of physician and patient adoption will depend on a number of factors, including the clinical indications for which a product candidate is approved and its effectiveness compared to other therapies, cost and the availability of reimbursement and other coverage from third party payors, our ability to educate patients and healthcare providers regarding a new therapy, and the effectiveness of our sales and marketing efforts. Furthermore, we will face significant competition, often from products sold and marketed by companies with far greater resources than Diffusion, and our failure to effectively compete may prevent us from achieving significant market penetration.

•    With respect to any such future products available only by prescription, if we are unable to achieve and maintain coverage and adequate levels of reimbursement from third party payors – including governmental health programs such as Medicare and Medicaid and private insurance companies – and access to such third party payors’ drug formularies, the commercial success of those products may be severely hindered. If any such products do not demonstrate attractive efficacy profiles, they may not qualify for coverage and reimbursement and, even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate, may require co-payments that patients find unacceptably high, and may vary from payor to payor, and there is no assurance that coverage and reimbursement levels necessary to achieve commercial success will be obtained..

•    Any such future products candidates that we commercialize will be subject to ongoing and continued regulatory review, including rules and regulations of the FDA and similar non-U.S. governmental authorities relating to advertising, marketing and labeling (including restrictions on the promotion of off-label use), potential REMS requirements, routine manufacturing and other review, and required compliance with GLP. If we or a regulatory agency discovers previously unknown problems with any such product, or any facility at or process by which it is manufactured, we may face restrictions on the sale or distribution of such product or on our Company as a whole, including regulatory actions requiring us to modify marketing or sales materials, suspend manufacturing or ongoing trials, initiate a recall or withdraw the product from the market entirely, enter into a consent decree, or submit to other civil or criminal investigations and penalties. If we are not able to achieve and maintain regulatory compliance, we may not be permitted to market our product candidates, which would adversely affect our ability to generate revenue and achieve or maintain profitability.

•    The biopharmaceutical and pharmaceutical industries are highly regulated and the potential for future legislative reform provides uncertainty and potential threats to our business and our potential future revenue and profitability of any such future products. In the U.S., there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system intended to contain or reduce the costs of medical products and medical services including those described under the heading Part I – Item 1. Business – Certain Other Legislation and Regulations – Current Healthcare Laws and Regulations. Additional state and federal healthcare reform measures may be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our products once approved or additional pricing pressures. We cannot predict the likelihood, nature, or extent of government regulation that may arise from future legislation or administrative or executive action, whether in the U.S. or other market territories we may pursue.
