Previous wording

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. For the nine months ended September 30, 2025 and 2024, we reported a net loss of $40.0 million and $11.8 million, respectively. As of September 30, 2025, we had an accumulated deficit of $98.3 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. ARD-101 and ARD-201 will require substantial additional development time and resources before we would be able to apply for or receive marketing approvals and begin generating revenue from product sales.

Previous wording

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 trials of ARD-101 and ARD-201 and our other product candidates and programs, and any future product candidates we may develop. Our expenses will increase substantially if our product candidates successfully complete early clinical and other studies, and also could increase beyond expectations if the FDA or comparable foreign regulatory authorities require us to perform 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 will 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.

Previous wording

As of September 30, 2025, we had cash, cash equivalents and short-term investments of approximately $126.4 million. Based on our current operating plan, we believe that our existing cash, cash equivalents and short-term investments will be sufficient to fund our projected operations into 2027. 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 potential 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. Such financing may result in dilution to our stockholders, imposition of burdensome debt covenants and repayment obligations, or other restrictions that may affect our business.

Previous wording

We currently have no products that are approved for commercial sale. Our lead product candidate, ARD-101, is an oral gut-restricted small-molecule agonist of certain TAS2Rs expressed in the gut lumen for which we have initiated a Phase 3 clinical trial for hyperphagia associated with PWS. While we also have a clinical-stage program, ARD-201, for which we intend to initiate two Phase 2 clinical trials, we have not yet determined the formulation of ARD-201. The success of our business, including our ability to finance our company and generate revenue in the future, will primarily depend on the successful development, regulatory approval and commercialization of our lead product candidate. We cannot be certain that ARD-101 or any future product candidates will receive regulatory approval or be successfully commercialized even if we receive regulatory approval.

Current wording

We currently have no products that are approved for commercial sale. Our lead product candidate, ARD-101, is an oral, largely gut-restricted small-molecule agonist of certain TAS2Rs expressed on luminally accessible enteroendocrine cells lining the gut for which we have initiated a Phase 3 clinical trial for hyperphagia associated with PWS. In February 2026, we voluntarily paused enrollment and dosing in the HERO trial and the open label extension (OLE) trial based on reversible cardiac observations in a healthy volunteer study. We are conducting a comprehensive review of the data and collaborating with the FDA to determine next steps and expect to provide further guidance in the second quarter of 2026. The success of our business, including our ability to finance our company and generate revenue in the future, will primarily depend on the successful development, regulatory approval and commercialization of our lead product candidate. We cannot be certain that ARD-101 or any other current or future product candidates will receive regulatory approval or be successfully commercialized even if we receive regulatory approval.

Previous wording

Before we can generate any revenue from sales of our lead product candidate, ARD-101, or any future product candidates, we must undergo additional preclinical and clinical development, regulatory review and approval in one or more jurisdictions. In addition, if one or more of our product candidates are approved, we must ensure access to sufficient commercial manufacturing capacity and conduct significant marketing efforts in connection with any commercial launch. These efforts will require substantial investment, and we may not have the financial resources to continue development of our product candidates. Our ability to generate product revenues, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates. The success of our product candidates will depend on several factors, including the following:

Previous wording

Prior to obtaining approval to commercialize any product candidate in the United States or abroad, we must demonstrate with sufficient evidence from adequate and well-controlled clinical trials, and to the satisfaction of the FDA or comparable foreign regulatory authorities, that such product candidates are safe and effective for their intended uses. Results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe the preclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA or comparable foreign regulatory authorities. Our approach is designed to target biological pathways associated with alleviating hunger, specifically by developing selective compounds targeting TAS2Rs, is unproven and may not result in marketable products. Although multiple studies are currently underway, to date, this mechanism has not been definitively proven to successfully treat hunger-associated conditions. Targeting TAS2Rs is a novel approach in a rapidly developing field, and there can be no assurance that we will not experience currently unknown problems or delays in developing our product candidates, that such problems or delays will not result in unanticipated costs, or that any such development problems can be solved. In addition, the regulatory pathway for ARD-201, which we plan to administer as a fixed-dose combination after formulation development of ARD-101 and a DPP-4 inhibitor, may differ from the pathway for our other product candidates in development. We cannot be certain as to the requirements and processes that may be involved in the development of and seeking regulatory approval for this program. The FDA may also require us to conduct additional preclinical studies, clinical trials or other studies for our product candidates either prior to or after approval, or it may object to elements of our clinical development programs.

Previous wording

ARD-101 and ARD-201 are still in clinical development and their risk of failure is high. To obtain the requisite regulatory approvals to commercialize any product candidates, we must demonstrate through extensive preclinical studies and lengthy, complex and expensive clinical trials that our product candidates are safe and effective in humans for the indications for which we intend to commercialize our product candidates. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure or delay can occur at any time during the preclinical or clinical trial process. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate data to demonstrate the safety and effectiveness of a product candidate. Preclinical tests and Phase 1 and Phase 2 clinical trials are primarily designed to test safety, to study pharmacokinetics and pharmacodynamics and to understand the side effects of product candidates at various doses and regimens. Success in preclinical studies and early or Phase 2 clinical trials does not ensure that later large-scale efficacy trials will be successful nor does it predict final results. Our product candidates may fail to show the required safety and effectiveness through clinical trials despite positive results in preclinical studies or having successfully advanced through initial clinical trials, particularly because we are targeting novel pathways that have not yet been tested in later-stage clinical trials.

Our Phase 3 HERO trial, in which we will evaluate the effect of ARD-101 on hyperphagia-related behavior in PWS, is currently limited to subjects 13 years of age and older, although in October 2025, we reached alignment with the FDA on a protocol amendment to change the minimum age of eligibility to participate in the trial from 13 to 10 years of age or older. In the future, we may seek regulatory approval to include subjects that are younger than 10 years of age in our Phase 3 HERO trial. However, certain factors may preclude us from receiving regulatory approval to treat younger pediatric subjects, including potential disagreements regarding appropriate dose and dose escalation, product presentation for possibly lower doses, validity of patient-reported outcomes in younger, actively growing patients, and avoiding inappropriate hunger suppression in these growing individuals. We can neither predict if the FDA or comparable foreign regulatory authorities will approve the use of our product candidates or programs in younger pediatric subjects, nor provide an estimate for the timing of such approval, if any. Furthermore, if the FDA or comparable foreign regulatory authorities do not approve the use of our product candidates or programs in this population, such product candidates or programs will not be labeled for use in these subjects. Given that the median lifespan of PWS patients is 30 years, the size of our market opportunity in this indication will be more limited if ARD-101 is not ultimately approved in pediatric patients.

Current wording

Our Phase 3 HERO trial, evaluating the effect of ARD-101 on hyperphagia-related behavior in PWS, was limited to subjects 10 years of age and older after reaching alignment with the FDA in October 2025 on a protocol amendment to change the minimum age of eligibility to participate in the trial from 13 to 10 years of age or older. In December 2025, we submitted an additional protocol amendment seeking to further lower the minimum age of eligibility to participate in the trial to 7 years of age. If we restart HERO or another trial to evaluate ARD-101 in PWS patients, certain factors may preclude us from receiving regulatory approval to treat younger pediatric subjects, including potential disagreements regarding appropriate dose and dose escalation, product presentation for possibly lower doses, validity of patient-reported outcomes in younger, actively growing patients, and avoiding inappropriate hunger suppression in these growing individuals. We can neither predict if the FDA or comparable foreign regulatory authorities will approve the use of our product candidates or programs in younger pediatric subjects, nor provide an estimate for the timing of such approval, if any.

Given that the median lifespan of PWS patients is currently 30 years, the size of our market opportunity in this indication will be more limited if ARD-101 is not ultimately approved in pediatric patients and does not result in a significant increase in patient lifespan. Following the voluntary pause of our clinical programs in February 2026, we are reviewing the HERO trial design and protocol in collaboration with the FDA and the previously agreed protocol elements may be revisited.

We will need to successfully complete pivotal clinical trials in order to obtain product approval from the FDA or comparable foreign regulatory authorities to market ARD-101, ARD-201 or any future product candidate. Carrying out pivotal clinical trials is a complicated process. We initiated a potentially pivotal Phase 3 HERO clinical trial in hyperphagia associated with PWS in December 2024; however, as an organization, we have not previously conducted any later stage or pivotal clinical trials. In order to do so, we have expanded our clinical management and regulatory capabilities, including hiring clinical, regulatory and quality personnel, and we expect to continue to need to expand our clinical management and regulatory capabilities, but may be unable to recruit and train qualified personnel. We also expect to continue to rely on third parties to conduct our pivotal clinical trials. See the subsection titled “—Risks Related to Our Dependence on Third Parties—We have relied and expect to continue to rely on third parties to conduct our preclinical studies and clinical trials, as well as investigator-initiated trials. If those third parties do not perform as contractually required, fail to satisfy legal or regulatory requirements, miss expected deadlines or terminate the relationship, our development programs could be delayed, more costly or unsuccessful, and we may never be able to seek or obtain regulatory approval for or commercialize our product candidates.” Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical trials in a way that leads to submission of an NDA and approval of ARD-101, ARD-201 or future product candidates. In addition, certain of our potential target indications may never have received FDA approval. We also plan to conduct a number of clinical trials 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. We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of product candidates that we develop. Failure to commence or complete, or delays in, our planned clinical trials, could prevent us from or delay us in commercializing our product candidates, which could adversely affect our business, operating results, prospects or financial condition.

In addition, no product candidate can receive FDA approval unless clinical trials show both safety and efficacy for each target indication in accordance with FDA or foreign country standards. We plan to conduct a number of clinical trials for multiple product candidates in parallel over the next several years depending on the outcome of our ongoing evaluation of our voluntarily paused clinical programs. This may be a difficult process to manage with our limited resources and may divert the attention of management.

Previous wording

Because we have limited financial and management resources, we focus on development programs and product candidates that we identify for specific indications. As such, we are currently primarily focused on the development of ARD-101 for the treatment of hyperphagia associated with PWS and our ARD-201 program for the treatment of obesity and obesity-related conditions. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other indications for our product candidates that later prove to have greater commercial potential. In particular, we are still exploring the potential clinical applications for ARD-201 in obesity and obesity-related conditions and our future decisions with respect to treatment areas and indications will be informed by the results of the POWER and STRENGTH trials. Moreover, to allow us to direct more resources to focus on the application of ARD-201, in the third quarter of 2025, we determined to delay indefinitely our plans to evaluate ARD-101 in a Phase 2 clinical trial for hyperphagia associated with hypothalamic obesity. 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 development programs and product 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 product candidate, we may relinquish valuable rights to that product 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 to such product candidate.

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 development programs and product candidates for specific indications may not yield any commercially viable products. We must continually assess the potential commercial viability of our research programs and product candidates, and we may decide to pause, discontinue or deprioritize development of any of our product candidates based upon such assessments, even if we obtain positive data from our product candidates in preclinical studies and clinical trials. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product 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 to such product candidate.

Previous wording

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the regulatory submission, preclinical studies, clinical trials, manufacturing, marketing and promotion of the product candidate in those countries.

Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our drugs is also subject to approval.

We plan to conduct certain clinical trials of ARD-101 and ARD-201 outside the United States, including, but not limited to, in the United Kingdom, South Korea, Romania, Italy, France, Spain, Canada and Australia. The acceptance of study data from clinical trials conducted outside the United States or another jurisdiction by the FDA or comparable foreign regulatory authority may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of recognized competence; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical power, must be met. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, we would need to conduct additional trials, which could be costly and time-consuming.

The FDA’s and comparable foreign regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. For example, the U.S. Supreme Court’s June 2024 decision in Loper Bright Enterprises v. Raimondo overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. The Loper decision could result in additional legal challenges to regulations and guidance issues by federal agencies, including the FDA, on which we rely. Any such legal challenges, if successful, could have a material impact on our business. The Loper decision also may result in increased regulatory uncertainty, inconsistent judicial interpretations, and other impacts to the agency rulemaking process, any of which could adversely impact our business and operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which could adversely affect business, operating results, prospects or financial condition.

Current wording

The FDA’s and comparable foreign regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. For example, the U.S. Supreme Court’s June 2024 decision in Loper Bright Enterprises v. Raimondo overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies’ reasonable interpretations of ambiguous federal statutes. The Loper decision could result in additional legal challenges to regulations and guidance issued by federal agencies, including the FDA, on which we rely.

Previous wording

Significant disruptions to the operations of government agencies, including from prolonged or repeated shutdown of the federal government, could adversely affect our business, financial condition and results of operations. Recently, beginning on October 1, 2025, the U.S. government shut down during which time certain regulatory agencies, such as the FDA and the SEC, furloughed certain employees and stopped critical activities. Additionally, on October 10, 2025, the U.S. government implemented substantial layoffs and workforce reductions in connection with the federal government shutdown, which has resulted in the suspension or delay of various government-funded programs. While the Company continues to monitor developments, there is no assurance that affected government employees or contractors will be reinstated and that government-funded programs will resume. The ability of the FDA to review and approve new products, to provide feedback on clinical trials and development programs, to meet with sponsors and to otherwise review regulatory submissions can be affected by a variety of factors, including government budget and funding levels, reductions in workforce, ability to hire and retain key personnel and accept the payment of user fees, substantial changes in leadership and shifting policy priorities as a result of changes in the presidential administration and its appointees tasked to oversee the agency, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result and may continue in the future. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Current wording

Significant disruptions to the operations of government agencies, including from prolonged or repeated shutdown of the federal government, could adversely affect our business, financial condition and results of operations.

Disruptions at the FDA and other agencies, including as a result of reductions in force, significant organizational changes, substantial leadership departures, and policy changes, may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, the current U.S. administration has discussed several changes to the reach and oversight of the FDA, which could affect its relationship with the pharmaceutical industry, transparency in decision making and ultimately the cost and availability of prescription drugs. Additionally, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough certain employees and stop certain critical activities. The current U.S. administration also recently announced plans to reduce the number of federal employees by establishing voluntary termination programs, by position eliminations or by involuntary terminations. If funding for the FDA is reduced, if the FDA workforce is reduced, or if government shutdowns continue or reoccur, any of these factors could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

Further, a prolonged or future shutdown of the U.S. federal government could materially impact the operations of the SEC. For example, the SEC announced that during the most recent U.S. federal government shutdown, it will not declare registration statements effective. In the event of an extended or future shutdown, the SEC may operate with limited staff or suspend certain functions altogether, which could delay the review or effectiveness of our filings, including registration statements or other financing-related disclosures. Such delays could adversely affect our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue to fund our operations.

The FDA or comparable foreign regulatory authorities may also face delays or resource constraints relating to foreign inspections, such as those that occurred during the COVID-19 pandemic. In response, such agencies may shift inspection priorities, may turn to remote regulatory assessments, or may issue other policies that could affect product approval timelines, which could have a material adverse effect on our business. A prolonged U.S. government shutdown or reductions in FDA funding or workforce may also affect inspection-related activities.

We have received Orphan Drug Designation for ARD-101 for the treatment of PWS, and we may seek Orphan Drug Designation for some or all of our other product candidates. However, we may not receive such designation, and we may not be able to maintain Orphan Drug Designation or orphan drug exclusivity for ARD-101, which could limit the potential profitability of our product candidates.

Current wording

We have received Orphan Drug Designation and Rare Pediatric Disease Designation for ARD-101 for the treatment of PWS, and we may seek Orphan Drug Designation and/or Rare Pediatric Disease Designation for some or all of our other product candidates. However, we may not receive either such designation, and we may not be able to maintain Orphan Drug Designation or Rare Pediatric Disease Designation or obtain a Rare Pediatric Disease priority review voucher or orphan drug exclusivity for ARD-101, which could limit the potential profitability of our product candidates.

Previous wording

In the United States, Orphan Drug Designation entitles a party to financial incentives such as opportunities for granting funding towards clinical trial costs, tax advantages and application fee waivers. If a drug or biologic with an Orphan Drug Designation subsequently receives marketing approval for the indication for which it has such designation, the product may be entitled to an expanded period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug and indication for that time period, except in limited circumstances. The applicable period is seven years in the United States.

The applicable period is seven years in the United States. An orphan drug benefiting pediatric patients can qualify as a drug for a Rare Pediatric Disease Designation as well. If so designated, the sponsor of the Rare Pediatric Disease designated product may be eligible for a rare pediatric disease priority review voucher, which would be issued in connection with FDA approval for the designated product. Under the Federal Food, Drug, and Cosmetic Act (the FDCA), a rare pediatric disease product application may be eligible for a rare pediatric disease priority review voucher if the drug receives marketing approval before September 30, 2029.

Previous wording

The FDA granted us an Orphan Drug Designation for the use of ARD-101 in PWS in August 2023, and we may also seek Orphan Drug Designation for some or all of our other product candidates. However, we may be unsuccessful in obtaining Orphan Drug Designation for other product candidates, and we may be unable to obtain or maintain the benefits associated with Orphan Drug Designation for ARD-101 or other product candidates for which we may receive such designations. The exclusivity granted under the Orphan Drug Designation may not effectively protect ARD-101 from competition because different drugs can be approved for the same condition, and orphan drug exclusivity does not prevent the FDA from approving the same or a different drug for another indication. The FDA may be able to subsequently approve a later application for the same drug for the same condition before the expiration of the seven-year exclusivity period if the FDA concludes that the later drug is clinically superior in that it is shown to be safer in a substantial portion of the target populations, more effective or makes a major contribution to patient care. In addition, 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 designation. Moreover, orphan-drug-exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to manufacture sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Orphan Drug Designation does not shorten the development time or regulatory review time of a drug and does not give the drug any advantage in the regulatory review or approval process. Additionally, even if we obtain orphan drug designation for a product candidate, we may not be able to obtain orphan drug exclusivity for that product candidate.

We may apply for a Breakthrough Therapy designation for ARD-101, ARD-201 and other future product candidates for one or more indications when we have placebo-controlled data and we believe that the clinical data may support such a designation for one or more product candidates. A Breakthrough Therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition with unmet medical need, and preliminary clinical evidence indicates that the drug, or biologic, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For product candidates that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Drugs and biologics designated as Breakthrough Therapies by the FDA may also be eligible for rolling review (submissions of portions of an application before the complete marketing application is submitted) and priority review.

We may apply for fast track designation, priority review or accelerated approval status for ARD-101, ARD-201 or for future product candidates. However, even if we receive fast track designation, priority review or accelerated approval status or other accelerated review designation for one or more of our product candidates, these designations do not assure that we will experience a faster development process, regulatory review or regulatory approval process compared to conventional FDA procedures. In addition, the FDA may withdraw a fast track, priority review, accelerated approval status or other accelerated review designation if it believes that the status or designation is no longer supported by data from our clinical development program. Additionally, qualification for any expedited review procedure does not ensure that we will ultimately obtain regulatory approval for such product candidate. Access to an expedited program may expedite the development or approval process, but it does not change the standards for approval.

Our reliance on these third parties for development activities will reduce our control over these activities. Nevertheless, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable trial protocol and legal, regulatory and scientific standards, and our reliance on the CROs, clinical trial sites, and other third parties does not relieve us of these responsibilities. For example, we will remain responsible for ensuring that each of our preclinical studies is conducted in accordance with GLPs, and clinical trials are conducted in accordance with GCPs. Moreover, the FDA and comparable foreign regulatory authorities require us to comply with GCPs for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections (including pre-approval inspections once an NDA or biologics license application is submitted to the FDA) of trial sponsors, clinical investigators, trial sites and certain third parties including CROs. If we, our CROs, clinical trial sites, or other third parties fail to comply with applicable GCP or other regulatory requirements, we or they may be subject to enforcement or other legal actions, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials complies with GCP regulations. Moreover, our business may be significantly impacted if our CROs, clinical investigators or other third parties violate federal or state healthcare fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.

We currently have collaborations with third parties to develop certain of our potential product candidates, although none of these collaborations relate to ARD-101 or ARD-201. In the future, we may seek collaboration arrangements for the commercialization, or potentially for the development, of other product candidates depending on the merits of retaining commercialization rights for ourselves as compared to entering into collaboration arrangements. For example, certain disease areas that we believe our product candidates address require large, costly and later-stage clinical trials, which a collaboration partner may be better positioned to finance and/or conduct.

Even if our patents are determined by a court to be valid and enforceable, they may not be interpreted sufficiently broadly to prevent others from marketing products similar to ours or designing around our patents. For example, third parties may be able to make products that are similar to ours but that are not covered by the claims of our patents. Third parties may assert that we or our licensors were not the first to make the inventions covered by our issued patents or pending patent applications. The claims of our or our licensors’ issued patents or patent applications when issued may not cover our product candidates or any future product candidates that we develop. We may not have freedom to commercialize unimpeded by the patent rights of others. Third parties may have patents that dominate, block or are otherwise relevant to our technology. For example, our ARD-201 is a program in which we plan to administer our proprietary bitter taste receptor agonist, denatonium acetate monohydrate, and a DPP-4 inhibitor as a fixed-dose combination after formulation development. However, we do not expect to be able to use a DPP-4 inhibitor in our ARD-201 program unless and until it is no longer protected by a patent. In addition, there may be prior public disclosures or other art that could be deemed to invalidate one or more of our patent claims. We may not develop additional proprietary technologies in the future, and, if we do, they may not be patentable.

Thus, we cannot guarantee that our current product candidates, or our commercialization thereof, do not and will not infringe any third party’s intellectual property. Because patent applications are maintained as confidential for a certain period of time (for example, patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases, not at all), until the relevant application is published, we may be unaware of third-party patents that may be infringed by commercialization of any of our product candidates, and we cannot be certain that we were the first to file a patent application related to a product candidate or technology. Moreover, because patent applications can take many years to issue, there may be currently-pending patent applications that may later result in issued patents that our product candidates may infringe. There is also no assurance that there is not prior art of which we are aware, but which we do not believe is relevant to our business, which may, nonetheless, ultimately be found to limit our ability to make, use, sell, offer for sale or import our products that may be approved in the future, or impair our competitive position.

Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we have licensed or that we may obtain in the future. For example, the complexity and uncertainty of European patent laws have also increased in recent years. In Europe, in June 2023, a new unitary patent system was introduced, which will significantly impact European patents, including those granted before the introduction of the system. Under the unitary patent system, after a European patent is granted, the patent proprietor can request unitary effect, thereby getting a European patent with unitary effect (the Unitary Patent). Each Unitary Patent is subject to the jurisdiction of the Unitary Patent Court (the UPC). As the UPC is a relatively new court system, there is little precedent for the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC will have the option of opting out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC may be potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the UPC. We cannot predict with certainty the long-term effects of the unitary patent system.

Moreover, any name we have proposed to use with our product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. Similar requirements exist in Europe. The FDA typically conducts a review of proposed product names, including an evaluation of potential for confusion with other product names. If the FDA or a comparable foreign regulatory authority objects to any of our proposed proprietary product names, we may be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. Furthermore, in many countries, owning and maintaining a trademark registration may not provide an adequate defense against a subsequent infringement claim asserted by the owner of a senior trademark. At times, competitors or other third parties may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. If we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH), and its implementing regulations, mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common healthcare transactions, as well as standards relating to the privacy and security of protected health information (“PHI”), including individually identifiable health information, as defined under HIPAA, which require the adoption of administrative, physical and technical safeguards to protect such information. Among other things, HITECH makes HIPAA’s security standards directly applicable to business associates, defined as independent contractors or agents of covered entities, which include certain health care providers, health plans and healthcare clearinghouses, that create, receive or obtain protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and security of health information and other personal data in certain circumstances, some of which are more stringent or otherwise different than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and criminal penalties;

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, (collectively, the ACA), was enacted in the United States, which substantially changed the way healthcare is financed by both governmental and private insurers in the United States and significantly affected the pharmaceutical industry. The ACA, among other things, subjected biologic products to potential competition by lower-cost biosimilars, addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program (the MDRP) are calculated for drugs and biologics that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the MDRP, extended manufacturer Medicaid rebate obligations to utilization by individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs and biologics, and established a new Medicare Part D coverage gap discount program. Since its enactment, there have been judicial, congressional, and executive branch challenges to the ACA, which have resulted in delays in the implementation of, and action taken to repeal or replace, certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. In addition, there have been a number of health reform initiatives that have impacted the ACA. For example, on August 16, 2022, the Inflation Reduction Act (the IRA) became law, which, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminated the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and through a newly established manufacturer discount program. In addition, the IRA imposes new manufacturer financial liability on certain drugs under Medicare Part D, allowing the U.S. government to negotiate Medicare Part B and Part D price caps for certain high-cost drugs and biologics without generic or biosimilar competition, subject to certain exemptions applicable to orphan drugs. It is possible that the ACA will be subject to judicial or congressional challenges in the future. It is unclear how such challenges, and the healthcare reform measures of the current administration, will impact the ACA and our business.
