Previous wording

Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are a clinical stage biopharmaceutical company with a limited operating history, which may make it difficult to evaluate the success of our business to date and assess our future viability. Since our inception in 2016, we have focused primarily on organizing and staffing our company, business planning, establishing our intellectual property portfolio, raising capital, developing our structure-based drug discovery platform, identifying and developing our product candidates, conducting preclinical studies and, more recently, clinical studies, and providing general and administrative support for these operations. Our approach to the discovery and development of product candidates based on our structure-based drug discovery platform is unproven, and we do not know whether we will be able to develop any product candidates that succeed in clinical development or commercially. Further, aleniglipron, our product candidate for obesity, overweight and related conditions, ACCG-2671, our oral small molecule amylin receptor agonist development candidate for the treatment of obesity, ANPA-0073, our product candidate for selective or muscle-sparing weight loss, and LTSE-2578, our product candidates for IPF, are in early clinical development and our other product candidates and programs are in preclinical development or discovery stages. Accordingly, we have not yet demonstrated an ability to successfully obtain regulatory approvals, manufacture a commercial scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a history of successfully developing and commercializing biopharmaceutical products.

We have no products approved for commercial sale and have not generated any revenue to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred significant losses since our inception and expect to continue to incur significant and increasing operating losses for at least the next several years. Our net losses were $108.5 million and $122.5 million for the six months ended June 30, 2025 and year ended December 31, 2024, respectively. As of June 30, 2025, we had an accumulated deficit of $437.6 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. All of our product candidates will require substantial additional development time and resources, including additional funding to conduct Phase 3 clinical studies of aleniglipron, before we would be able to apply for or receive marketing approvals and begin generating revenue from product sales. We expect to continue to incur losses for the foreseeable future, and we anticipate that our expenses will increase substantially as we continue our development of, seek marketing approval for and potentially commercialize any of our product candidates, recruit and maintain key personnel and seek to identify, assess, acquire, in-license or develop additional product candidates.

The development of biopharmaceutical product candidates is capital-intensive. We expect our expenses to increase substantially in connection with our ongoing and planned activities, particularly as we conduct our ongoing and planned preclinical studies and clinical studies of aleniglipron, ACCG-2671, ANPA-0073, LTSE-2578 and any future product candidates we may develop. Our expenses will increase substantially if any of our product candidates successfully complete early clinical and other studies, and also could increase beyond expectations if the FDA or foreign authorities require us to perform clinical and other studies in addition to those that we currently anticipate. Because the outcome of any clinical trial or preclinical study is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidates. In addition, we have and expect to continue to incur additional costs associated with operating as a public company. Furthermore, if we obtain marketing approval for our product candidates, we expect to incur significant expenses related to manufacturing, marketing, sales and distribution. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

Based on our current operating plan, we believe that our cash, cash equivalents and short-term investments, as of June 30, 2025, will be sufficient to fund our operating expenses and key clinical milestones through at least 2027, including all planned aleniglipron studies for Phase 3 readiness but excluding Phase 3 registrational studies. We have based these estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses and other similar arrangements. Even if we believe we have sufficient capital for our current or future operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic considerations.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses or other similar arrangements. For example, in October 2023, we issued and sold an aggregate of 21,617,295 ordinary shares and 2,401,920 newly designated non-voting ordinary shares in the Private Placement. In June 2024, we issued and sold an aggregate of 10,427,017 ADSs in the Follow-On Offering. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our ADS holders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as limitations on our ability to incur additional debt, make capital expenditures or declare dividends. If we raise funds through collaborations or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us.

We are in the early stages of our development efforts and have four product candidates, aleniglipron, ACCG-2671, ANPA-0073 and LTSE-2578, in early clinical development. In June 2024, we reported positive topline data from our Phase 2a obesity study, in which aleniglipron demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks (p<0.0001, using least-squares means (“LSM”) and analyzed based on the primary efficacy estimand using a mixed model for repeated measures) and demonstrated generally favorable safety and tolerability results following repeated, daily dosing up to 120 mg. Furthermore, we explored a new tablet formulation of aleniglipron in a capsule to tablet PK study, which demonstrated a placebo-adjusted mean weight loss of up to 6.9% with the tablet formulation at 12 weeks (p<0.0001, using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures). In July 2024, we submitted an IND to the FDA to support the initiation of a Phase 2b study in chronic weight management and received FDA allowance in August 2024. In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study, a randomized, double-blind, placebo-controlled, dose-range finding study of aleniglipron in approximately 220 adult participants living with obesity (BMI ≥ 30 kg/m2), or overweight (BMI ≥ 27 kg/m2) with at least one weight-related comorbidity. Participants start at 5 mg of aleniglipron (or placebo) with a four-week titration schedule, reaching target doses of 45 mg, 90 mg and 120 mg. The primary endpoint is percent change in body weight from baseline to week 36. Secondary endpoints include safety and tolerability of the monthly titration scheme, as well as PK of aleniglipron. In the fourth quarter of 2024, we initiated a randomized, double-blind, placebo-controlled dose-range finding Phase 2 study of aleniglipron, known as ACCESS II, in approximately 82 adult participants living with obesity or overweight with at least one weight-related comorbidity. The study is designed to evaluate two higher doses of aleniglipron. Participants start at 5 mg of aleniglipron (or placebo) and follow a four-week titration schedule up to target doses of 120 mg, 180 mg and 240 mg. In February 2025, we completed enrollment in the ACCESS and ACCESS II studies, and we expect to report topline data from both studies in the fourth quarter of 2025.

Previous wording

Clinical drug development is expensive and can take many years to complete, and its outcome is inherently uncertain. Our clinical studies may not be conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial process. For example, we depend on the availability of non-human primates (“NHPs”) to conduct certain preclinical studies that we are required to complete prior to submitting an IND and initiating clinical development. There is currently a global shortage of NHPs available for drug development. This has caused the cost of obtaining NHPs for our preclinical studies to increase dramatically and, if the shortage continues, could also result in delays to our development timelines. Despite promising preclinical or clinical results, any product candidate can unexpectedly fail at any stage of preclinical or clinical development. The historical failure rate for product candidates in our industry is high. Furthermore, the results from clinical studies or preclinical studies of a product candidate may not predict the results of later clinical studies of the product candidate, and interim results of a clinical trial are not necessarily indicative of final results. For example, the preliminary topline nature of aleniglipron results, the length of the study and sample size may render these results not necessarily indicative of the results for our future clinical studies for aleniglipron and may not be comparable to other weight loss products or product candidates, including other oral selective GLP-1RAs. In addition, given the size of the Phase 2a obesity cohort, the primary efficacy endpoint of weight loss was calculated using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures. This means that we drew on all available data, including data from patients that did not follow-up at 12 weeks. The model estimates how patients with missing data would have responded based on patients who continued the study and had similar

Product candidates in later stages of clinical studies may fail to show the desired safety and efficacy characteristics despite having progressed through preclinical studies and initial clinical studies. In particular, while we have conducted, or are conducting certain preclinical studies of our product candidates, the predictive value of these studies with respect to future testing in humans is limited, particularly in indications where animal models are less developed.

Previous wording

Even if our clinical studies are completed, the results may not be sufficient to obtain marketing approval for our product candidates. In clinical studies that are based on preclinical studies and early clinical studies, it is not uncommon to observe unexpected results, and many product candidates fail in clinical development despite very promising early results. Moreover, preclinical and clinical data may be susceptible to varying interpretations and analyses. A number of companies in the biopharmaceutical industry have suffered significant setbacks in clinical development even after achieving promising results in earlier studies. In addition, in some cases, external experts or regulatory authorities disagreed with such companies’ views and interpretations of the data and results from earlier preclinical studies or clinical studies. As we investigate aleniglipron for obesity, overweight and related conditions, ACCG-2671 for obesity, ANPA-0073 for selective and muscle-sparing weight loss, and LTSE-2578 for IPF, we may encounter new and unforeseen difficulties. Similarly, any future product candidates we may develop may not be able to progress from preclinical to Phase 1 clinical development. For the foregoing reasons, we cannot be certain that our ongoing and planned clinical studies and preclinical studies will be successful. Any of the foregoing occurrences may harm our business, financial condition and prospects significantly.

In order to obtain FDA approval to market our product candidates, we must demonstrate the safety and efficacy of our product candidates in humans to the satisfaction of the FDA. To meet these requirements, we will have to conduct adequate and well-controlled clinical studies. In addition, before we can initiate clinical studies for any product candidate, we must submit the results of preclinical studies to the FDA or comparable foreign regulatory authorities along with other information, including information about product candidate chemistry, manufacturing and controls and our proposed clinical trial protocol, as part of an IND or similar regulatory submission, and we are also required to submit comparable applications to foreign regulatory authorities for clinical studies outside of the United States. In July 2024, we submitted an IND to the FDA to support initiation of a Phase 2b study of aleniglipron in chronic weight management and received FDA allowance in August 2024. In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study. We dosed the first patient in the ACCESS II study in the fourth quarter of 2024. We may be required to obtain additional FDA approval prior to evaluating aleniglipron at higher doses of 180 mg and 240 mg under our ACCESS II study. Since we have not previously tested these higher doses, we cannot be certain whether they have a favorable safety or tolerability profile. If we are unable to obtain such additional FDA approval, we may not be able to conduct our ACCESS II study as planned.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such studies are being conducted, by a Data Safety Monitoring Board for such trial or by the FDA or applicable foreign authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or applicable foreign authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

Furthermore, our efforts to build relationships with patient communities may not succeed, which could result in delays in patient enrollment in our clinical studies. If we encounter any delays in enrolling such additional participants, this may further delay our clinical trial. In addition, any negative results we may report in clinical studies of our product candidate may make it difficult or impossible to recruit and retain patients in other clinical studies of that same product candidate. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on our ability to develop our product candidates, or could render further development impossible. For example, the impact of public health epidemics may delay or prevent patients from enrolling or from receiving treatment in accordance with the protocol and the required timelines, which could delay our clinical studies, or prevent us or our partners from completing our clinical studies at all, and harm our ability to obtain approval for such product candidate. Further, if patients drop out of our clinical studies, miss scheduled doses or follow-up visits, or otherwise fail to follow clinical trial protocols, the integrity of data from our clinical studies may be compromised or not accepted by the FDA or applicable foreign authorities, which would represent a significant setback for the applicable program. In addition, we may rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical studies and, while we intend to enter into agreements governing their services, we will be limited in our ability to compel their actual performance. Such delays or failures could adversely affect our business, operating results and prospects.

Moreover, if any of our product candidates are associated with undesirable side effects in clinical studies or have characteristics that are unexpected, we may elect to abandon their development or limit their development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective, which may limit the commercial value for the product candidate if approved. We may also be required to modify our trial plans based on findings in our ongoing clinical studies. In our completed Phase 1 SAD and Phase 1b MAD study of aleniglipron, the following adverse events occurred and were considered probably or possibly related to the study drug: nausea, headache, vomiting, dehydration, decreased appetite, dizziness, and diarrhea. In our completed Phase 2a study of aleniglipron, the following adverse events occurred and were considered probably or possibly related to the study drug: nausea, headache, vomiting, decreased appetite, dyspepsia, and diarrhea. In our completed Phase 1 SAD and MAD study of ANPA-0073, the following adverse events occurred and were considered probably or possibly related to the study drug: blood creatine phosphokinase increase, dizziness, electrocardiogram T wave inversion, diarrhea, headache, lethargy, nausea, vomiting, chills, palpitations, and sinus tachycardia. However, further analysis may reveal AEs inconsistent with the safety results observed. Many compounds that initially showed promise in early-stage testing have later been found to cause side effects that prevented further development of the compound. In addition, regulatory authorities may draw different conclusions or require additional testing to confirm these determinations.

We are early in our development efforts for our product candidates, and we will need to successfully complete pivotal clinical studies in order to seek FDA or applicable foreign authority approval to market aleniglipron, ACCG-2671, ANPA-0073, LTSE-2578 and any future product candidates we may develop. Carrying out clinical studies and the submission of NDAs is complicated. We have not conducted any later stage or pivotal clinical studies, have limited experience as a company in preparing, submitting and prosecuting regulatory filings and have not previously submitted an NDA or other applicable foreign regulatory submission for any product candidate. We also plan to conduct a number of clinical studies for multiple product candidates in parallel over the next several years. This may be a difficult process to manage with our limited resources and may divert the attention of management. In addition, we are currently planning for later stage interactions with FDA, and other foreign regulatory agencies; however, we cannot guarantee timely or shift alignment on our clinical trial designs, Phase 3 dose rationale and overall size of the data base needed for any future marketing applications. Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical studies in a way that leads to regulatory submission and approval of any of our product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining marketing approvals of product candidates that we develop. Failure to commence or complete, or delays in, our planned clinical studies, could prevent us from or delay us in submitting NDAs for and commercializing our product candidates.

Previous wording

Regulatory authorities in some jurisdictions, including the United States, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States, or a patient population of greater than 200,000 individuals in the United States but for which there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States alone. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and application fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation, however, neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the targeted indication, then the drug is entitled to a seven-year period of marketing exclusivity that precludes the applicable regulatory authority from approving another marketing application for the same chemical entity for the same indication for the exclusivity period except in limited situations, such as a showing of clinical superiority to the product with orphan drug exclusivity or where the manufacturer is unable to assure sufficient product quantity. For purposes of small molecule drugs, the FDA defines “same drug” as a drug that contains the same active moiety and is intended for the same use as the drug in question. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan drug designation.

In addition, as we advance toward commercialization in the future, tariffs and trade restrictions could hinder our ability to establish cost-effective production capabilities, negatively impacting our growth prospects.

Current wording

Current or future tariffs will result in increased research and development expenses, including with respect to increased costs associated with APIs and drug product. In addition, such tariffs will increase our supply chain complexity and could also potentially disrupt our existing supply chain.

We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates and related raw materials for preclinical and clinical development, as well as for commercial manufacture if any of our product candidates receive marketing approval. This reliance increases the risk that we will not have sufficient quantities of our product candidates or products, if approved, or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts. Our APIs and drug product for our product candidates are currently provided by a supplier, WuXi STA, a subsidiary of WuXi AppTec, and we expect to rely on this supplier for the foreseeable future. Contract manufacturing organizations may become subject to legislation, trade restrictions, sanctions, and other regulatory requirements by the U.S. government, which could restrict or even prohibit our ability to work with such entities, thereby potentially disrupting the supply of material to us. For example, the House of Representatives of the prior Congress (the 118th Congress) passed the BIOSECURE Act, which proposed prohibiting U.S. government contracts, grants, and loans to entities that use equipment and services from certain named Chinese biotech companies, which included WuXi AppTec and WuXi Biologics and certain of their respective subsidiaries and affiliates, and authorized the U.S. government to include additional Chinese biotechnology companies of concern. This version of the BIOSECURE Act included a grandfathering provision allowing biotechnology equipment and services provided or produced by named biotechnology companies of concern under a contract or agreement entered into before the effective date until January 1, 2032.

These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct also could involve the improper use of information obtained in the course of clinical studies or interactions with the FDA or applicable foreign authorities, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could have a negative impact on our business, financial condition, results of operations and prospects, including the imposition of significant fines or other sanctions.

As of the date of this Quarterly Report, we have not received any notice from any Chinese regulatory authority identifying us as a “critical information infrastructure operator,” “online platform operator”, “online platform service provider” or “online data processor,” or requiring us to go through the cybersecurity review procedures pursuant to the Revised CAC Measures and the Management Regulations. Based on our understanding of the Revised CAC Measures and the Management Regulations, we do not expect to become subject to cybersecurity review by the CAC for issuing securities to foreign investors because: (i) the clinical and preclinical data we handle in our business operations, either by its nature or in scale, do not normally trigger significant concerns over PRC national security; and (ii) we have not processed, and do not anticipate to process in the foreseeable future, personal information for more than one million users or persons. However, there remains uncertainty as to how the Revised CAC Measures, and the Management Regulations when it comes into effect in January 2025, will be interpreted or implemented; for example, neither the Revised CAC Measures nor the Management Regulations provides further clarification or interpretation on the criteria for determining those activities that “affect or may affect national security” and relevant Chinese regulatory authorities may interpret it broadly. Furthermore, there remains uncertainty as to whether the Chinese regulatory authorities may adopt new laws, regulations, rules, or detailed implementation and interpretation in relation, or in addition, to the Revised CAC Measures and the Management Regulations. While we intend to closely monitor the evolving laws and regulations in this area and take all reasonable measures to mitigate compliance risks, we cannot guarantee that our business and operations will not be adversely affected by the potential impact of the Revised CAC Measures, the Management Regulations or other laws and regulations related to privacy, data protection and information security.

We may in the future enter into license agreements with third parties under which we receive rights to intellectual property that are important to our business. Our rights to use the technology we license are subject to the continuation of and compliance with the terms of those agreements. These intellectual property license agreements may require of us various development, regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations. If we fail to comply with our obligations under these agreements, we use the licensed intellectual property in an unauthorized manner or we are subject to bankruptcy-related proceedings, the terms of the license agreements may be materially modified, such as by rendering currently exclusive licenses non-exclusive, or it may give our licensors the right to terminate their respective agreement with us, which could limit our ability to implement our current business plan and materially adversely affect our business, financial condition, results of operations and prospects.

In some cases, we may not control the prosecution, maintenance or filing of the patents to which we hold licenses, or the enforcement of those patents against third parties. Hence, our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for our licensed intellectual property, in particular, those patents to which we have secured exclusive rights. Our licensors may not successfully prosecute the patent applications to which we are licensed in a manner consistent with the best interests of our business. Even if patents are issued in respect of these patent applications, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than we would. Without protection for the intellectual property we license, other companies might be able to offer substantially identical products for sale, which could adversely affect our competitive business position and harm our business prospects. Further, we may have limited control over these activities or any other intellectual property that may be in-

For example, we cannot be certain that such activities by licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that is licensed to us. It is possible that the licensors’ infringement proceeding or defense activities may be less vigorous than had we conducted them ourselves. In the event our licensors fail to adequately pursue and maintain patent protection for patents and applications they control, and to timely cede control of such prosecution to us, our competitors might be able to enter the market, which would have a material adverse effect on our business.

Given the amount of time required for the development, testing and regulatory review of our new product candidates such as aleniglipron, ACCG-2671, ANPA-0073, LTSE-2578 and any of our future product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. We expect to seek extensions of patent terms in the United States and, if available, in other countries where we are prosecuting patents. In the United States, the Drug Price Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration of the patent, which is limited to the approved indication (or any additional indications approved during the period of extension) as compensation for effective patent term lost during product development and FDA regulatory review process. However, we may not receive an extension if we fail to exercise due diligence during the testing phase or regulatory review process, fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. Only one patent per approved product can be extended, the extension cannot extend the total patent term beyond 14 years from approval and only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended. Further, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. Further, if this occurs, our competitors may be able to take advantage of our investment in development and clinical studies by referencing our clinical and preclinical data and launch their product candidates earlier than might otherwise be the case.
