Current wording

We are a clinical-stage biopharmaceutical company with a limited operating history.

Previous wording

We are a late clinical-stage biopharmaceutical company focused on developing small molecules engineered to restore neuronal health and slow neurodegeneration. Our limited operating history may make it difficult to evaluate the success of our business. Drug development is a highly uncertain undertaking and involves a substantial degree of risk. To date, we have not completed a pivotal clinical trial, obtained marketing approval for any drug candidate, manufactured a commercial scale drug candidate, or conducted sales and marketing activities necessary for successful drug candidate commercialization. Our history as a company makes any assessment of our future success and viability subject to significant uncertainty. We will encounter risks and difficulties frequently experienced by clinical-stage biopharmaceutical companies in rapidly evolving fields, and we have not yet demonstrated an ability to overcome such risks and difficulties successfully. If we do not address these risks and difficulties successfully, our business will suffer.

We may fail to or be unable to design and execute clinical trials to support marketing approval of fosgonimeton or any of our other drug candidates. We cannot be certain that our current or planned clinical trials or any other future clinical trials will be completed on time or be successful. We cannot guarantee that the FDA or foreign regulatory authorities will agree with our study design, protocol or protocol amendments, or statistical plan, or that they will interpret clinical trial results as we do, and more clinical trials could be required before we are able to submit applications seeking approval of our drug candidates. To the extent that the results of the clinical trials are not satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, we may be required to expend significant resources, which may not be available to us, to conduct additional clinical trials in support of potential approval of our drug candidates (including potential confirmatory or Phase 3 registrational trials). Even if regulatory approval is secured for any of our drug candidates, the terms of such approval may limit the scope and use of our drug candidate, which may also limit its commercial potential.

Previous wording

Our approach to targeting neurotrophic factors through the use of small molecules is based on a novel therapeutic approach, which exposes us to unforeseen risks. We have limited data from our Phase 1a/1b and Phase 2 clinical trials to date, and we cannot be certain that future trials will yield data in support of the safety, efficacy and tolerability of our drug candidates.

Previous wording

We have discovered and are developing a pipeline of small molecule drug candidates from which we have selected our lead drug candidate, fosgonimeton, which is under development to treat AD, Parkinson's Disease Dementia, or PDD, and Dementia with Lewy Bodies, or DLB. Our drug candidates target an endogenous neurotrophic factor which is expected to protect and repair neuronal networks, which we believe could ultimately result in improvements in clinical outcomes and disease-relevant biomarkers. The therapeutic promise of neurotrophic factors in neurodegenerative diseases had been hampered in earlier therapies by the lack of efficient and non-invasive delivery to the CNS. Our small molecule drug candidates are designed to penetrate the BBB and enhance the activity of a neurotrophic factor, but we cannot be certain of the safety and efficacy of our drug candidates in applicable patients or that our clinical trials will provide sufficient evidence that our design approach results in the intended therapeutic effect.

Previous wording

The primary and all secondary endpoints of our Phase 2 ACT-AD clinical trial in AD were not met by protocoled analysis. A subsequent post hoc analysis of the data in a pre-specified subgroup from patients on fosgonimeton without background AChEIs showed a meaningful, but not statistically significant, improvement in both ERP P300 latency and cognitive performance compared to placebo at 26 weeks. Although post hoc analyses cannot be used to establish efficacy, these analyses can be helpful in informing the design of current and future clinical studies. In addition, the primary endpoint of our Phase 2 SHAPE clinical trial in PDD and DLB was not met by protocoled analysis. Directionally positive results were observed for the 40 mg fosgonimeton dose group with improvements in cognitive, functional and biomarker measurements. In particular, the five patients in the modified intent to treat, or mITT, population treated with fosgonimeton 40 mg once daily saw improvement in ADAS-Cog13 individually, and collectively improved compared with placebo (n=7 mITT, one-sided p=0.0321). Results for patients in the 70 mg dose group were inconsistent.

Previous wording

Data from our Phase 1a/1b and Phase 2 clinical trials to date were obtained from a relatively small number of subjects and we cannot be certain that future trials involving a larger number of subjects and clinical sites will yield data in support of the safety, efficacy and tolerability of our drug candidates. We may ultimately discover that fosgonimeton, or any of our other small molecules, do not possess certain properties required for therapeutic effectiveness. We have limited evidence regarding the efficacy, safety and tolerability of fosgonimeton and other small molecules in our drug product pipeline. We may spend substantial funds attempting to develop these drug candidates and never succeed in doing so.

We have not received regulatory approval for fosgonimeton and cannot be certain that our approach will lead to the development of an approvable or marketable product, alone or in combination with other therapies. The primary and all secondary endpoints of the ACT-AD and SHAPE trials were not met by protocoled analysis. While we are continuing with the LIFT-AD study, we may not succeed in demonstrating safety and efficacy of fosgonimeton in our LIFT-AD trial or in other clinical trials.

Our prospects are highly dependent on the successful development of fosgonimeton. If we do not demonstrate the safety and efficacy of fosgonimeton in our LIFT-AD trial, we may explore strategic alternatives to maximize stockholder value, which could involve, without limitation, exploring the potential for a possible merger, business combination, investment, a purchase, license or other acquisition of assets or return of capital to stockholders.

Current wording

Our prospects are highly dependent on the successful development of ATH-1105. Following the September 2024 announcement of topline results from the Phase 2/3 LIFT-AD clinical trial of fosgonimeton showing that neither the trial’s primary endpoint nor its key secondary endpoints were met, we announced our intention to focus on advancing the clinical development program for ATH-1105 as a potential treatment for neurodegenerative diseases, including ALS and AD. Like fosgonimeton, ATH-1105 is a small molecule designed to positively modulate the HGF system. Although we are encouraged about the potential for ATH-1105 based on preclinical data, we may decide to discontinue development of some or all of our product candidates, including if we do not demonstrate the safety and efficacy of ATH-1105 in current and future clinical trials, and may pursue strategic alternatives to maximize stockholder value, which could involve, without limitation, exploring the potential for a possible merger, business combination, investment, a purchase, license or other acquisition of assets or return of capital to stockholders.

Previous wording

We have focused our research and development efforts on addressing CNS and PNS degenerative disorders. Collectively, efforts by pharmaceutical companies in the field of CNS and PNS degenerative disorders have seen very limited successes in product development. The development of CNS therapies presents unique challenges, including an imperfect understanding of the biology, the presence of the BBB that can restrict the flow of drugs to the brain, a frequent lack of translatability of preclinical study results in subsequent clinical trials and dose selection, and the product candidate having an effect that may be too small to be detected using the outcome measures selected in clinical trials or if the outcomes measured do not reach statistical significance. There are few effective therapeutic options available for patients with AD and other CNS or PNS disorders. Our future success is highly dependent on the successful development of our technology and our drug candidates for treating CNS and PNS disorders. Developing and, if approved, commercializing our drug candidates for treatment of CNS and PNS disorders subjects us to a number of challenges, including ensuring that we have selected the optimal doses, executing an appropriate clinical trial to test for efficacy and obtaining regulatory approval from the FDA and other regulatory authorities.

Previous wording

It is impossible to predict when or if any of our drug candidates will prove to be effective and safe in humans or will receive regulatory approval.

Current wording

Our lead drug candidate, ATH-1105, is currently in clinical development for the potential treatment of ALS, and we have additional drug candidates in development. It is impossible to predict when or if any of our drug candidates will prove to be effective and safe in humans or will receive regulatory approval.

Previous wording

Before obtaining regulatory approvals for the commercial sale of our drug candidates, we must demonstrate through lengthy, complex and expensive nonclinical studies and clinical trials that our drug candidates are both safe and effective for each target indication. Nonclinical and clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the nonclinical study and clinical trial processes, and, because our drug candidates are in an early stage of development, there is a high risk of failure and we may never succeed in developing marketable products. The results of nonclinical studies and early clinical trials of our drug candidates may not be predictive of the results of later-stage clinical trials. Although product candidates may demonstrate promising results in nonclinical studies and early clinical trials, they may not prove to be safe or effective in subsequent clinical trials. For example, testing on animals occurs under different conditions than testing in humans and therefore, the results of animal studies may not accurately predict safety and effectiveness in humans. There is typically an extremely high rate of attrition from the failure of product candidates proceeding through nonclinical studies and clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy profile despite having progressed through nonclinical studies and initial clinical trials. For example, our Phase 1a/b clinical trial, which enrolled 88 patients, including only 11 patients with mild-to-moderate AD, of whom seven patients were treated with fosgonimeton and the other four patients were randomized to the control, suggested improvements in brain network activity including potentially positive effects on brain function. However, our Phase 2 ACT-AD clinical trial in AD, which included a larger patient population, approximately 60% of which were receiving background AChEIs, did not meet its primary endpoint of a change in ERP P300 latency for the full study population nor did it meet the secondary endpoints. Although a post hoc analysis of results from ACT-AD in a pre-specified subgroup suggested positive effects on measures of cognition, function and neurodegeneration in patients taking fosgonimeton alone without background AChEIs, we cannot be sure that data from future trials will support our earlier findings or demonstrate the safety and effectiveness of fosgonimeton for treatment of AD to the satisfaction of the FDA and other regulatory authorities in order to support regulatory approval. Likewise, early, smaller-scale studies, biomarker analyses, and clinical trials with a single or relatively few clinical trial sites may not be predictive of eventual safety and effectiveness in large-scale pivotal clinical trials across multiple clinical trial sites. Even if data from a pivotal clinical trial are positive, regulators may …

However, our subsequent Phase 2 ACT-AD clinical trial in AD did not meet its primary endpoint of a change in ERP P300 latency for the full study population nor did it meet the secondary endpoints, and our Phase 2/3 LIFT-AD clinical trial in AD did not meet its primary endpoint (the GST, a combination of results from measures of cognition (ADAS-Cog11) and function (ADCS-ADL23)) nor its key secondary endpoints of ADAS-Cog11 and ADCS-ADL23. Based on these results, we decided to pause further development of fosgonimeton and to shift our focus to the clinical development of ATH-1105.

Previous wording

In some instances, there can be significant variability in safety or efficacy results between different nonclinical studies and clinical trials of the same product candidate due to numerous factors, including changes in clinical trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants. For example, we believe the topline results of our Phase 2 ACT-AD clinical trial may have differed from the treatment data from our Phase 1a/b clinical trial at least in part due to differences in the patient population and treatment duration, and potential effects from background AChEI treatment. If future trials show that the effect of fosgonimeton when given in combination with add-on background AChEIs is diminished, we may be required to seek a narrower indication or restrict our target population to those where fosgonimeton shows a greater effect, which could have a material adverse effect on our business and prospects.

Previous wording

On July 6, 2021, we announced the initiation of an open-label extension for the LIFT-AD and ACT-AD trials and in May 2022 we announced the extension of the open label extension for an additional 12 months. In May 2023, we amended the open-label extension trial to further extend the trial by an additional 12 months, and in April 2024, we amended the open-label extension trial to further extend the trial by an additional 18 months. Upon completion of the 26-week treatment period during the LIFT-AD or ACT-AD trials, patients may continue on the open-label extension and receive treatment with fosgonimeton for up to an additional 48 months. Investigators and patients remain blinded to treatment group assignment in the original trials. Such open-label extension studies are, and some of the clinical trials we conduct in the future may be, open-label in study design conducted at a limited number of clinical sites on a limited number of patients. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved drug or placebo. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge.

Further, conducting clinical trials in foreign countries, as we intend to do for our drug candidates, presents additional risks that may delay completion of our clinical trials. These risks include the failure of enrolled patients in foreign countries to adhere to clinical protocol as a result of differences in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory schemes, as well as political and economic risks relevant to such foreign countries.

Because we have limited financial and managerial resources, we focus on research programs and drug candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other drug candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and drug candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular drug candidate, we may relinquish valuable rights to that drug candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights.

In February 2023, the Securities and Exchange Commission, or SEC, sent us a subpoena seeking documents and information relating to, among other things, our former chief executive officer’s alteration of images in certain research papers. We cooperated with the SEC with respect to the subpoena. On March 29, 2024, we received a letter from the SEC stating that the SEC had concluded its investigation without any enforcement action against us.

From time to time, we may also disclose interim data from our nonclinical studies and clinical trials. For example, in October 2022 we announced that an independent DMC had conducted an unblinded interim efficacy and futility analysis with respect to our Phase 2/3 LIFT-AD clinical trial. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our common stock.

Additionally, we rely on data received from clinical trials, whether preliminary or final, to inform decisions on future clinical trials, including trial design, trial size, and whether or not to initiate additional clinical trials (including any potential confirmatory or Phase 3 registrational trials). For example, in November 2020, we initiated ACT-AD, an exploratory Phase 2 clinical trial, to better understand the overall effects of fosgonimeton on working memory processing speed and cognitive measures. Topline results of ACT-AD were announced in June 2022. We used these data to help inform strategic decisions around LIFT-AD and expect to use these data to help inform strategic decisions in the future around current clinical trials and any additional trials that we may initiate. Topline results are based on a preliminary analysis of then-available data, and a more comprehensive and full review of the data may result in different conclusions, which could have a negative impact on our decisions regarding any additional trials for fosgonimeton. There is no assurance that the amendments to our ongoing LIFT-AD trial based on our findings from the ACT-AD trial and our interim analysis of the LIFT-AD trial will ultimately result in a successful trial. For example, our biomarker data may not translate into a statistically significant clinical benefit, the FDA may not agree with our statistical plan or analyses, or the trial may not be sufficiently powered for our endpoint measures.

For example, in November 2020, we initiated ACT-AD, an exploratory Phase 2 clinical trial, to better understand the overall effects of fosgonimeton on working memory processing speed and cognitive measures. Topline results of ACT-AD were announced in June 2022. We used these data to help inform strategic decisions around LIFT-AD.

If the interim, topline, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our drug candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Current wording

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular drug candidate or drug and our company in general.

Previous wording

If we are delayed or unsuccessful in enrolling the desired number of subjects in our trials, whether as a result of the outcomes of prior trials conducted by us, competing clinical trials, overly stringent eligibility requirements, or other factors, our clinical trial results could be delayed, the costs of our clinical trials could materially increase, and the overall development timeline for fosgonimeton could be negatively impacted. For example, enrollment in our clinical trials had slowed due to the effects of the COVID-19 pandemic, including governmental restrictions imposed in Australia, where certain of our clinical trial sites were located. In our ACT-AD clinical trial, this slowed recruitment resulted in a change in the timing of topline results from our Phase 2 ACT-AD clinical trial, which were announced in June 2022. We cannot ensure that similar enrollment issues will not occur again in the future. Even if we are successful in enrolling the targeted number of subjects in our trials, the FDA and other regulators may request additional clinical trials with larger numbers of subjects (including potential confirmatory or Phase 3 registrational trials) as a condition to any regulatory approval.

Current wording

If we are delayed or unsuccessful in enrolling the desired number of subjects in our trials, whether as a result of the outcomes of prior trials conducted by us, competing clinical trials, overly stringent eligibility requirements, or other factors, our clinical trial results could be delayed, the costs of our clinical trials could materially increase, and the overall development timeline for ATH-1105 or any other drug candidates we may seek to develop could be negatively impacted. Even if we are successful in enrolling the targeted number of subjects in our trials, the FDA and other regulators may request additional clinical trials with larger numbers of subjects as a condition to any regulatory approval.

Previous wording

Drug candidates that we may successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. For example, the FDA recently granted traditional approval for lecanemab, a drug developed by Biogen Inc. and Eisai Co., Ltd., and Eli Lilly and Company received approval for an amyloid beta-directed antibody in July 2024. Key product features that would affect our ability to effectively compete with other therapeutics include the efficacy, safety and convenience of our drug products. Our competitors may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our drug candidates. The availability of reimbursement from government and other third-party payors will also significantly affect the pricing and competitiveness of our drug products. For example, the U.S. Centers for Medicare & Medicaid Services, or CMS, announced a two-part National Coverage Determination, or NCD, under which Medicare will cover monoclonal antibodies that target amyloid (or plaque) for the treatment of AD that receive traditional approval from the FDA under coverage with evidence development. Additionally, for drugs that FDA has not determined to have shown a clinical benefit or that received an accelerated approval, Medicare will provide coverage in FDA or NIH approved clinical trials. In June 2023, CMS announced that Medicare will cover new Alzheimer’s drugs with traditional FDA approval when a physician and clinical team participate in CMS’ registry to collect evidence about how these drugs work in the real world. Current and future CMS coverage restrictions on classes of drugs that encompass our drug candidates could have a material adverse impact on our ability to commercialize our drug candidates, if approved, generate revenue and attain profitability. It is unclear how future CMS coverage decisions and policies will impact our business. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. For additional information regarding our competition, see the section titled “Part I, Item 1 – Business—Competition” in our Annual Report on Form 10-K filed with the SEC on February 22, 2024.

Previous wording

We also may choose to evaluate drug candidates in combination with one or more therapies that have not yet been approved for marketing by the FDA or comparable foreign regulatory authorities. We will not be able to market and sell any drug candidate we develop in combination with an unapproved therapy for a combination indication if that unapproved therapy does not ultimately obtain marketing approval either alone or in combination with our drug product. In addition, unapproved therapies face the same risks described with respect to our drug candidates currently in development and clinical trials, including the potential for serious adverse effects, delay in their clinical trials and lack of FDA approval. If the FDA or comparable foreign regulatory authorities do not approve these other drugs or revoke their approval of, or if safety, efficacy, quality, manufacturing or supply issues arise with, the drugs we choose to evaluate in combination with our drug candidate we develop, we may be unable to obtain approval of or market such combination therapy.

Previous wording

We will require substantial additional funding to finance our operations, complete the development and commercialization of fosgonimeton, and develop and commercialize other and future drug candidates. If we are unable to raise this funding when needed, we may be forced to delay, reduce, or eliminate our drug product development programs or other operations.

Current wording

We will require substantial additional funding to finance our operations, complete the development and commercialization of ATH-1105, and develop and commercialize other current and potential drug candidates. If we are unable to raise this funding and access capital when needed, we may be forced to delay, reduce, or eliminate our drug product development programs, commercialization efforts or other operations.

Previous wording

Since our inception, we have used substantial amounts of cash to fund our operations, and we expect our expenses to increase substantially in the foreseeable future in connection with our ongoing activities, particularly as we continue the research and development of, initiate clinical trials of, and seek marketing approval for, fosgonimeton. Developing fosgonimeton and conducting clinical trials for the treatment of AD, PDD, DLB, and any other indications that we may pursue in the future will require substantial amounts of capital. In addition, if weobtain marketing approval for fosgonimeton or any future drug candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing, and distribution. Furthermore, we expect to continue to incur additional costs associated with operating as a public company.

Current wording

Since our inception, we have used substantial amounts of cash to fund our operations, and we will continue to incur expenses for the foreseeable future in connection with our ongoing activities, particularly as we continue the research and development of, initiate clinical trials of, and seek marketing approval for, ATH-1105. Developing ATH-1105 and conducting clinical trials for the potential treatment of ALS and/or AD, and any other indications that we may pursue in the future will require substantial amounts of capital. In addition, if we obtain marketing approval for ATH-1105 or any future drug candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing, and distribution. Furthermore, we expect to continue to incur additional costs associated with operating as a public company.

Previous wording

Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. As of June 30, 2024, we had cash, cash equivalents and investments of $91.8 million. Based upon our current operating plan, we estimate that our existing cash, cash equivalents and investments will be sufficient to fund our operating expenses and capital expenditure requirements through at least the next 12 months following the date of this report. However, changing circumstances may cause us to increase our spending significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control. We may need to raise additional funds sooner than we anticipate if we choose to expand more rapidly than we presently anticipate.

Current wording

Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. As of September 30, 2024, we had cash, cash equivalents and investments of $68.9 million. Based upon our current operating plan, we estimate that our existing cash, cash equivalents and investments will be sufficient to fund our operating expenses and capital expenditure requirements through at least the next 12 months following the date of this report.

Current wording

the willingness of the FDA and EMA to accept ATH-1105 clinical trial data, as well as data from any completed and planned clinical and nonclinical studies and other work, as the basis for review and approval of ATH-1105 for ALS and the potential need for additional clinical trials;

Previous wording

Our ability to raise additional funds will depend on financial, economic and other factors, many of which are beyond our control. For example, the current inflationary economic environment, health epidemics, and rising interest rates have resulted in a disruption of global financial markets. If the disruption persists or deepens, we could be unable to access additional capital, which could negatively affect our ability to consummate certain corporate development transactions or other important, beneficial or opportunistic investments. If additional funds are not available to us when we need them, on terms that are acceptable to us, or at all, we may be required to take steps that could adversely impact our business, including delaying, limiting, reducing or terminating nonclinical studies, clinical trials or other research and development activities or eliminating one or more of our development programs altogether, or delaying, limiting or reducing or terminating efforts to prepare for commercialization of any future approved drug products. We currently have a shelf registration statement effective and an existing ATM equity offering program, however, our ability to raise capital under this registration statement and through our ATM equity offering program may be limited by, among other things, SEC rules and regulations impacting the eligibility of smaller companies to use Form S-3 for primary offerings of securities.
