Current report

Conducting nonclinical studies and clinical trials, obtaining regulatory approvals, and preparing for potential commercialization are costly, time-consuming, and subject to significant uncertainty. As of December 31, 2025, we had cash, cash equivalents and marketable securities of $160.7 million. Based on our current operating plan and assumptions, we believe our existing capital resources will be sufficient to fund our operations into 2028. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. In addition, our operating plan may change, and we may require additional capital sooner than anticipated. Our future need for additional funding depends on many factors, including:

Current report

the number and scope of development, nonclinical and clinical programs we decide to pursue, and the timing, cost and progress of activities related to such programs;

Current report

the progress, costs and results of our clinical trials of budoprutug in pMN, ITP, and SLE, our Phase 1 clinical trial of the SC formulation of budoprutug, our Phase 1 clinical trial of CLYM116, and any future clinical trials of our product candidates;

Current report

the cost of regulatory requirements, regulatory submissions and timing of regulatory approvals;

Current report

the costs involved in prosecuting and enforcing patent and other intellectual property claims;

Current report

the impact of inflationary pressures on salaries and wages, and costs of goods and transportation expenses, including the impact of tariffs and other trade restrictions;

Current report

We may be required to make significant payments under our license and asset purchase agreements, including development, regulatory, commercial and sales‑based milestone, and royalty payments. These obligations may be substantial and strain our capital resources, and we may not have sufficient funds when payments become due. If we fail to meet payment or diligence obligations, licensors may terminate the agreements, resulting in the loss of rights to budoprutug, CLYM116 or any other product candidate we may license.

Current report

As a result of the Acquisition, certain legacy Tenet agreements effectively became agreements of ours, including the Asset Purchase Agreement, the CRH Agreement, and the ProBioGen Agreement. In addition, in January 2025, we entered into the Mabworks Agreement, pursuant to which we obtained licenses to develop, manufacture and commercialize CLYM116, and products containing CLYM116, in certain territories.

Current report

Our future success depends on developing our product candidates, obtaining regulatory approval and successfully commercializing our product candidates. Delays or failures in clinical development, regulatory review, or commercialization could prevent or delay us from generating revenue or achieving profitability. Regulatory approval processes are lengthy, complex, and inherently uncertain, and regulatory expectations may evolve during development.

Current report

Advertising and promotion of any product candidate that obtains approval in the U.S. will be heavily scrutinized by the FDA, the Department of Justice, the Office of Inspector General of the HHS, state attorneys general, members of Congress and the public. For example, there has been increased scrutiny by the current government administration on advertising practices, and recently, the FDA issued a generic “notice letter” to a substantial number of companies directing such companies to “remove any noncompliant advertising and bring all promotional communications into compliance.”

Current report

Further, clinical development in immunology and autoimmune diseases, including pMN, ITP, SLE, and IgAN, presents inherent challenges, such as heterogeneous disease courses, variable endpoints, competition to enroll patients in trials, background therapy effects, and long-duration studies, which may delay or impair our ability to demonstrate clinical benefit and obtain regulatory approval for our product candidates. Regulators may require additional studies, protocol modifications, or changes to endpoints, and guidance from regulators can evolve, which could affect our development plans and timing. Manufacturing scale‑up, assay validation, and process comparability for biologics can also delay trials or approvals. Any delays could increase our costs, shorten any effective exclusivity periods we may obtain for a product candidate, and enable competitors to reach the market earlier than us, reducing commercial viability for our product candidates.

Companies developing CD19 CAR-T and CAR-NK therapies include but are not limited to Novartis AG, Bristol Myers Squibb Company, Cabaletta Bio, Inc., Kyverna Therapeutics, Inc. and Nkarta, Inc.

Current report

Disruptions at the FDA and other government agencies from funding cuts, personnel losses, regulatory reform, government shutdowns and other developments could hinder our ability to obtain guidance from the FDA regarding our clinical development program and develop and secure approval of our product candidates in a timely manner, which would negatively impact our business.

Current report

Disruptions at the FDA and other agencies, including workforce changes, budget constraints, regulatory reform, government shutdowns, or public health emergencies could delay inspections, guidance from the FDA, and application review, which could hinder our ability to secure approval of our product candidates in a timely manner. Even with the user‑fee program established under the PDUFA, resource constraints could delay PDUFA dates, and changes in government policy or enforcement priorities may alter review practices and post‑approval obligations with respect to the FDA or other comparable regulatory agencies.

Current report

The FDA and comparable regulatory agencies in foreign jurisdictions, such as the EMA and CHMP, play an important role in the development of our product candidates by providing guidance on our clinical development programs and reviewing our regulatory submissions, including INDs, requests for special designations and marketing applications. If these oversight and review activities are disrupted, then correspondingly our ability to develop and secure timely approval of our product candidates could be impacted in a negative manner.

Current report

For example, the recent loss and retirement of FDA leadership and personnel could lead to disruptions and delays in FDA guidance, review and approval of our product candidates. In July 2025, the Trump Administration began to carry out layoffs at the FDA and, in November 2025, Congress agreed to provide full-year funding for the FDA through September 30, 2026, at a slight decrease compared to previous spending levels. There were several reports in 2025 of the FDA failing to meet its PDUFA goal dates for approval of an NDA or BLA due to heavy workload and limited resources.

Current report

There is also substantial uncertainty as to how regulatory reform measures being implemented by the Trump Administration across the government will impact the FDA and other federal agencies with jurisdiction over our activities. For example, since taking office, the President has issued a number of executive orders that could have a significant impact on the manner in which the FDA conducts its operations and engages in regulatory and oversight activities. If these or other orders or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

Current report

Accordingly, if any of the foregoing developments and others impact the ability of the FDA to provide us with guidance regarding our clinical development programs or delay the FDA’s review and processing of our regulatory submissions, including INDs, NDAs, and BLAs, our business would be negatively impacted. Further, the current and any future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Current report

On August 16, 2022, the IRA was signed into law by President Biden. The new legislation has implications for Medicare Part D, which is a program available to individuals who are entitled to Medicare Part A or enrolled in Medicare Part B to give them the option of paying a monthly premium for outpatient prescription drug coverage.

Current report

Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations with Medicare (beginning in 2026), with prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program (that began in 2025). The IRA permits the Secretary of the HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years.

Current report

On June 6, 2023, Merck & Co. filed a lawsuit against the HHS and CMS asserting that, among other things, the IRA’s Drug Price Negotiation Program for Medicare constitutes an uncompensated taking in violation of the Fifth Amendment of the Constitution. Subsequently, a number of other parties with similar constitutional claims against the HHS and CMS. HHS has generally won the substantive disputes in these cases or succeeded in getting claims dismissed for lack of standing. On May 8, 2025, the U.S. Court of Appeals for the Third Circuit rejected AstraZeneca L.P.’s challenge to the Medicare price negotiation program, finding that the program did not violate the company’s due process rights under the Constitution since there is no protected property interest in selling goods to Medicare beneficiaries at a price higher than what the government is willing to pay in reimbursement.

Current report

In addition, the Trump Administration has taken a number of actions to reduce the costs of pharmaceutical products. For example, on April 15, 2025, President Trump issued an Executive Order which directs HHS to take steps to reduce the prices of pharmaceutical products. Such measures include streamlining the state drug importation program and modifying provisions of the 340B program. Further, on May 12, 2025, President Trump issued an additional Executive Order calling on pharmaceutical manufacturers to voluntarily reduce the prices of medicines in the U.S. The Order provides that if such actions do not lower the costs of pharmaceuticals, the Secretary of HHS would pursue other actions, including proposing a rulemaking that imposes MFN pricing in the U.S. Thereafter, on July 31, 2025, the President issued letters to 17 pharmaceutical companies reiterating the requirements of the May 12, 2025, Executive Order and demanding that such companies extend MFN pricing to Medicaid patients, guarantee MFN pricing for newly-launched drug products, return increased revenues abroad to American patients and provide for direct purchasing at MFN pricing. Since that time, virtually all of these pharmaceutical companies have entered into agreements with the administration to provide for lower prices on certain pharmaceuticals.

Current report

This may be especially true with respect to products approved pursuant to the accelerated approval pathway. State Medicaid programs and other payers are developing strategies and implementing significant coverage barriers, or refusing to cover these products outright, arguing that accelerated approval drugs have insufficient or limited evidence despite meeting the FDA’s standards for accelerated approval. In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize our product candidates, if and when approved, and any other products we may develop.

Current report

Actual or alleged non‑compliance by us could result in investigations, significant civil or criminal penalties, exclusion of our company from government programs, reputational harm, and operational restrictions. Non-compliance could adversely affect our ability to operate our business and our results of operations.

Current report

If our product candidates regulated as biologics are approved, they may face biosimilar competition, which could reduce our pricing power with respect to such product candidate and market share. Future legislative or regulatory changes in the U.S. or EU could shorten data exclusivity periods and affect our commercial prospects. Substitution dynamics, payer policies, and evolving guidance from the FDA or EMA could introduce uncertainty that may increase competitive pressure and compress net pricing.

Current report

In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted relating to non-patent exclusivity. For example, the European Commission launched a review of EU pharmaceutical legislation in November 2020. On December 11, 2025, the European Parliament and Council reached a provisional political agreement on the legislation, which is expected to be adopted by mid-2026. Key changes include updating regulatory data exclusivity to a new system with 8 years data exclusivity and a reduced market exclusivity period to 1 year, which can be extended if specific conditions are fulfilled. These provisions are expected to be adopted in the second quarter of 2026 and to take effect in mid-2028. If the legislation is finalized in line with the provisional political agreement, it will have a profound impact on the pharmaceutical industry in the EU.

Current report

Additionally, we could face heightened risks with respect to obtaining marketing authorization in the U.K. as a result of the withdrawal of the U.K. from the EU, commonly referred to as Brexit. As of January 1, 2025, the MHRA, is responsible for approving all medicinal products destined for the U.K. market (i.e., Great Britain and Northern Ireland), and the EMA will no longer have any role in approving medicinal products destined for Northern Ireland. The MHRA relies on the HMR as the basis for regulating medicines. The HMR has incorporated into domestic law the body of EU law instruments governing medicinal products that pre-existed prior to Brexit. On April 28, 2025, the U.K. Parliament adopted amendments to improve and strengthen the U.K.’s clinical trials regulatory regime, which will take effect on April 28, 2026. These changes were needed since the current U.K. requirements are based upon the now-repealed EU Clinical Trials Directive (2001/20/EC), which has been replaced by the European CTR (Regulation EU No 536/2014). Since the U.K. left the EU prior to the date on which the EU CTR took effect, the U.K. legal framework did not benefit from the same revisions as occurred at EU level.

Current report

As of January 1, 2024, a new IRP applies which intends to facilitate approval of pharmaceutical products in the U.K. The IRP is open to applicants that have already received an authorization for the same product from one of the MHRA’s specified RRs. The RRs notably include the EMA and regulators in the EEA member states for approvals in the EU centralized procedure and mutual recognition procedure as well as the FDA (for product approvals granted in the U.S.). The RR assessment must have undergone a full and standalone review, and RR assessments based on reliance or recognition cannot be used to support an IRP application. A CHMP positive opinion or an Mutual Recognition/Decentralised Reliance Procedure positive end of procedure outcome is an RR authorization for the purposes of IRP.

Current report

We do not have any manufacturing facilities. We contract with third parties, including single-source manufacturers, for the manufacture of materials for our product candidates, and we expect to continue to rely on such third parties for the manufacture of clinical and commercial supply of our product candidates. Reliance on these third parties introduces risks such as loss of control over quality and timing, regulatory compliance, supply interruptions, and potential misappropriation of proprietary information. If a third-party manufacturer fails to meet our requirements or terminates the relationship, we may not be able to secure an alternative in a timely or cost-effective manner, which could delay or prevent the development or commercialization of our product candidates.

Current report

Changes in and uncertainty surrounding U.S. and international trade policies, particularly with respect to China, may adversely impact our business and operating results.

Current report

We are exposed to evolving U.S. and international trade policies, particularly those targeting China, which can directly impact our supply chain, costs, and ability to collaborate with Chinese partners. Recent and proposed U.S. legislation, including the BIOSECURE Act and Section 1260H of the National Defense Authorization Act, may restrict or prohibit federal funding for contracts with certain Chinese biotechnology companies and could limit our ability to work with key suppliers and collaborators such as Mabworks.

Current report

Our collaboration with Mabworks is central to our pipeline, and any restrictions, tariffs, or sanctions affecting Chinese biotech firms could require us to identify and qualify alternative suppliers or partners, which may not be feasible on a timely or cost-effective basis. In addition, tariffs on pharmaceutical products and ingredients imported from China, as well as potential retaliatory actions by the Chinese government, could increase our manufacturing costs, disrupt supply of raw materials, and delay development timelines.

Current report

The regulatory environment remains fluid, and future trade agreements, export controls, or sanctions could further impact our operations, costs, and competitive position. We may need to invest significant resources to adapt our supply chain, ensure compliance, and mitigate risks associated with geopolitical tensions and regulatory changes.

Current report

For example, in February 2024, U.S. lawmakers called for investigations into and the imposition of possible economic sanctions against Chinese biotechnology companies WuXi AppTec and WuXi Biologics (together, Wuxi) over alleged ties to the Chinese military. Subsequently, in December 2025, as part of the Fiscal Year 2026 National Defense Authorization Act, President Trump signed into law the BIOSECURE Act. Under the BIOSECURE Act, U.S. government agencies cannot (1) buy or obtain biotechnology equipment or services provided by biotechnology companies of concern (BCCs), (2) enter into, extend, or renew a contract with any entity using biotechnology equipment or services provided by a BCC to perform a government contract, or (3) expend, loan or grant funds for biotechnology equipment or services provided by a BCC, whether directly or through a loan or grant recipient. The BIOSECURE Act does not name specific companies as BCCs but treats any company on the Department of Defense 1260H list of “Chinese military companies” as a BCC. On December 18, 2025, the Chairs of multiple Senate and House committees, including the House Select Committee on China, sent a letter to the Department of Defense recommending that Wuxi be added to the 1260H list, which would make it a BCC. The 1260H list was updated by the Department of Defense in January 2024 and January 2025. On February 13, 2026, the Department published an updated list, which included WuXi AppTec, but then abruptly withdrew the list. The implications of this action remain unclear.

Current report

Any unfavorable government policies on international trade, such as export controls, capital controls or tariffs, may increase the cost of manufacturing our product candidates and platform materials, affect the demand for our product candidates (if and once approved), the competitive position of our product candidates, and import or export of raw materials and finished product candidates used in our nonclinical studies and clinical trials, particularly with respect to any product candidates and materials that we import from China. On September 25, 2025, via a post on Truth Social, President Trump announced that, beginning October 1, 2025, all branded or patented drugs imported in the U.S. would face a 100% tariff. At the same time, President Trump indicated that these tariffs could be avoided by building pharmaceutical manufacturing facilities in the U.S. Thereafter, President Trump delayed the October 1st effective date of the tariffs on branded or patented pharmaceutical products announcing that the Trump Administration had now “begun preparing” tariffs on manufacturers that do not build in the U.S. or enter into a most-favored-nation drug pricing agreement with the Trump Administration. As a result of changes in tariffs that have been announced or implemented, and the underlying uncertainty currently surrounding international trade, we could experience a negative impact to our costs of materials and production processes, and supply chain disruptions and delays as a result of any new tariff policies or trade restrictions. We cannot yet predict the effect of the recently imposed U.S. tariffs on imports, or the extent to which other countries, in particular, China, will impose and maintain quotas, duties, tariffs, taxes or other similar restrictions upon imports or exports in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business.

Current report

If we are unable to obtain, maintain, or enforce sufficient patent and other intellectual property rights, or if those rights are limited in scope, we may not be able to compete effectively or to develop, manufacture, or commercialize our product candidates. Licenses and collaborations may include diligence, milestone, royalty, field-of-use, or territorial restrictions; failure to comply can lead to termination and loss of rights. Complex license terms and disputes (scope, sublicensing, ownership, payments) can impact our freedom to operate, timelines, and costs.

Current report

Our patent applications may not issue or may issue with limited scope, and issued patents can be challenged or circumvented, reducing our ability to prevent competitors from developing similar therapies. Oppositions, post-grant reviews, inter partes reviews, or litigation can narrow, invalidate, or render patents unenforceable, increasing costs and impacting collaborations and financing. Prosecution, maintenance, or enforcement errors, or lack of alignment with licensors, may compromise protection or priority.

Current report

Patent challenges, including oppositions, post-grant reviews, inter partes reviews, derivations, and litigation, can narrow, invalidate, or render our patents unenforceable, reducing exclusivity and enabling competitors to commercialize similar technologies. Adverse outcomes may limit our ability to prevent competition, shorten patent duration, or require costly and time-consuming legal proceedings.

Current report

Our reliance on third parties for development, manufacturing, and other services requires us to share trade secrets and confidential information, increasing the risk of misappropriation, inadvertent disclosure, or incorporation into others’ technology. While we use confidentiality and related agreements, these may not provide adequate protection or remedies, and monitoring compliance is challenging. If competitors lawfully obtain or independently develop our trade secrets, or if unauthorized disclosure occurs, our competitive position could be impaired.

Under the Mabworks Agreement, we are subject to significant potential future obligations, including payment of development and regulatory milestones and royalties on net product sales, as well as other obligations. The Mabworks Agreement sets forth specific development, regulatory and commercial events and the related payments that we would be obligated to make to Mabworks, if and when such events occur. For additional information on the terms of the Mabworks Agreement, please refer to Part 1, Item 1 of this Annual Report on Form 10-K under the section titled “License Agreements”.

Previous report

We had cash, cash equivalents and marketable securities of $212.5 million and $106.8 million at December 31, 2024 and 2023, respectively.

Previous report

Based upon our current operating plan and assumptions, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our operations through 2027. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. In addition, we will need additional capital to advance and expand our research pipeline, conduct preclinical studies and clinical trials, proceed to develop and commercialize any approved products, and explore other pipeline opportunities. Our estimates of the sufficiency of our cash, cash equivalents and marketable securities are based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. Further, changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned.

Previous report

Conducting preclinical studies and clinical trials, pursuing regulatory approvals, establishing outsourced manufacturing relationships and successfully manufacturing and commercializing our product candidates is, and will be, very time-consuming, expensive and an uncertain process that takes years to complete. Our future need for additional funding depends on many factors, including:

Previous report

Additional capital may not be available to us, or even if it is, the cost of such capital may be high. We may be forced to obtain additional capital before reaching clinical or regulatory milestones, when our stock price or trading volume or both are low, or when the general market for life sciences companies is weak. Raising capital under any of these or similar scenarios, if we can raise any at all, may lead to significant dilution to our existing stockholders.

Previous report

We may never generate the necessary data or results required to obtain marketing approval for our product candidates or generate revenue from the sale of any products for which we may obtain marketing approval.

Previous report

Even if we can generate revenues from the sale of any of our product candidates that may be approved, we may not become profitable and may need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce our operations.

Previous report

In the U.S., engaging in impermissible promotion products for off-label uses can also subject us to false claims litigation under federal and state statutes, which can lead to numerous actions, including civil, criminal and/or administrative penalties and fines and agreements that materially restrict the manner in which we promote or distribute our drug products. These false claims statutes include the federal False Claims Act, which allows the federal government, or any individual relator or whistleblower on behalf of the federal government to bring a lawsuit against a pharmaceutical company alleging submission of false or fraudulent claims, or causing to present such false or fraudulent claims, for payment by a federal program such as Medicare or Medicaid. If the government prevails in the lawsuit, the individual relator may share in any fines or settlement funds. Since 2004, these False Claims Act lawsuits against pharmaceutical companies have increased significantly in volume and breadth, leading to several substantial civil and criminal settlements based on certain sales practices promoting off-label drug uses. This growth in litigation has increased the risk that a pharmaceutical company will have to defend a false claim action, pay settlement fines or restitution, agree to comply with burdensome reporting and compliance obligations, and be excluded from the Medicare, Medicaid and other federal and state healthcare programs. If we do not lawfully promote our products once they have received regulatory approval, we may become subject to such litigation and, if we are not successful in defending against such actions, those actions could have a material adverse effect our business, results of operations, financial condition and cash flows and future prospects.

Previous report

In certain circumstances, the FDA and other regulatory authorities allow companies to engage in truthful, non-misleading, and non-promotional scientific communications concerning their products. For example, in October 2023, the FDA published draft guidance outlining the agency’s non-binding policies governing the distribution of scientific information on unapproved uses to healthcare providers. This draft guidance calls for such communications to be truthful, non-misleading, factual, and unbiased and include all information necessary for healthcare providers to interpret the strengths and weaknesses and validity and utility of the information about the unapproved use. In addition, under guidance from the FDA and the Pre-Approval Information Exchange Act, signed into law as part of the Consolidated Appropriations Act of 2023, companies may also promote information that is consistent with the prescribing information and proactively speak to formulary committee members of payors regarding data for an unapproved drug or unapproved uses of an approved drug. We may engage in these discussions and communicate with healthcare providers, payors and other constituencies in compliance with all applicable laws, regulatory guidance and industry best practices. We will need to carefully navigate the FDA’s various regulations, guidance and policies, along with recently enacted legislation, to ensure compliance with restrictions governing promotion of our product candidates.

Previous report

In addition, we could be adversely affected by several significant administrative law cases decided by the U.S. Supreme Court in 2024. In Loper Bright Enterprises v. Raimondo, for example, the U.S. Supreme Court overruled Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., which for 40 years required federal courts to defer to permissible agency interpretations of statutes that are silent or ambiguous on a particular topic.

Previous report

The U.S. Supreme Court stripped federal agencies of this presumptive deference and held that courts must exercise their independent judgment when deciding whether an agency such as the FDA acted within its statutory authority under the Administrative Procedure Act (APA). Additionally, in Corner Post, Inc. v. Board of Governors of the Federal Reserve System, the U.S. Supreme Court held that actions to challenge a federal regulation under the APA can be initiated within six years of the date of injury to the plaintiff, rather than the date the rule is finalized.

Previous report

The decision appears to give prospective plaintiffs a personal statute of limitations to challenge longstanding agency regulations. Another decision, Securities and Exchange Commission v. Jarkesy, overturned regulatory agencies’ ability to impose civil penalties in administrative proceedings. These decisions could introduce additional uncertainty into the regulatory process and may result in additional legal challenges to actions taken by federal regulatory agencies, including the FDA and the Centers for Medicare & Medicaid Services (CMS).

Previous report

In addition to potential changes to regulations as a result of legal challenges, these decisions may result in increased regulatory uncertainty and delays and other impacts, any of which could adversely impact our business and operations.

Previous report

delays in reaching agreement on acceptable terms with prospective contract research organizations (CROs) and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;

Previous report

Further, in January 2022, the new Clinical Trials Regulation (EU) No 536/2014 became effective in the EU and replaced the prior Clinical Trials Directive 2001/20/EC. This regulation aims at simplifying and streamlining the authorization, conduct and transparency of clinical trials in the EU. Under the coordinated procedure for the approval of clinical trials, the sponsor of a clinical trial to be conducted in more than one EU Member State will only be required to submit a single application for approval. The submission will be made through the Clinical Trials Information System, a clinical trials portal overseen by the EMA and available to clinical trial sponsors, competent authorities of the EU Member States and the public.

Previous report

Further, clinical trials that we may undertake in the future will likely contain endpoints that require subjective assessments and subject us to a substantial risk of “placebo effect”. While a product candidate may show clinical activity or therapeutic benefit, a high placebo effect in a clinical trial will make it difficult to ascertain that benefit or to show a statistically significant effect of the product candidate as compared to the control arm and may ultimately cause a clinical trial to fail. Moreover, principal investigators for our future clinical trials may serve as scientific advisors or consultants to us and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or a comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected the interpretation of the study. The FDA or a comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or a comparable foreign regulatory authority, as applicable, and may ultimately lead to the denial of marketing approval of our product candidates.

Previous report

Delays in the completion of any preclinical studies or clinical trials of our product candidates will increase our costs, slow down our product candidate development and approval process and delay or potentially jeopardize our ability to commence product sales and generate product revenue.

Previous report

In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. Any delays to our preclinical studies or clinical trials that occur as a result could shorten any period during which we may have the exclusive right to commercialize such product candidate, enable our competitors to bring products to market before we do, and significantly reduce the commercial viability of such product candidate. Any of these occurrences may harm our business, financial condition and prospects significantly.

Previous report

Disruptions at the FDA, the U.S. Securities and Exchange Commission and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

Previous report

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels; ability to hire and retain key personnel; ability to accept the payment of user fees; and statutory, regulatory and policy changes. Average review times at the FDA have fluctuated in recent years as a result and review times may increase if budget and funding levels are decreased. In addition, government funding of the U.S. Securities and Exchange Commission (SEC) and other government agencies on which our operations may rely, including those that fund research and development activities, are subject to the political process, which is inherently fluid and unpredictable.

Previous report

On July 9, 2021, President Biden signed Executive Order 14063, which focuses on, among other things, the price of pharmaceuticals. The order directs HHS to create a plan within 45 days to combat “excessive pricing of prescription pharmaceuticals and enhance domestic pharmaceutical supply chains, to reduce the prices paid by the federal government for such pharmaceuticals, and to address the recurrent problem of price gouging.” On September 9, 2021, HHS released its plan to reduce pharmaceutical prices. The key features of that plan are to: (a) make pharmaceutical prices more affordable and equitable for all consumers and throughout the health care system by supporting pharmaceutical price negotiations with manufacturers; (b) improve and promote competition throughout the prescription pharmaceutical industry by supporting market changes that strengthen supply chains, promote biosimilars and generic drugs, and increase transparency; and (c) foster scientific innovation to promote better healthcare and improve health by supporting public and private research and making sure that market incentives promote discovery of valuable and accessible new treatments.

Previous report

On August 15, 2024, the HHS published the results of the first Medicare drug price negotiations for ten selected drugs that treat a range of conditions, including diabetes, chronic kidney disease and rheumatoid arthritis. The prices of these ten drugs will become effective on January 1, 2026. On January 17, 2025, CMS announced its selection of 15 additional drugs covered by Part D for the second cycle of negotiations by February 1, 2025. While there had been some questions about the current administration’s position on this program, CMS issued a public statement on January 29, 2025, declaring that lowering the cost of prescription drugs is a top priority of the new administration and CMS is committed to considering opportunities to bring greater transparency in the negotiating program. This second cycle of negotiations with participating drug companies will occur during 2025, and any negotiated price for this second set of drugs will be effective starting January 1, 2027.

In addition, the IRA potentially raises legal risks with respect to individuals participating in a Medicare Part D prescription drug plan who may experience a gap in coverage if they required coverage above their initial annual coverage limit before they reached the higher threshold, or “catastrophic period” of the plan. Individuals requiring services exceeding the initial annual coverage limit and below the catastrophic period, must pay 100% of the cost of their prescriptions until they reach the catastrophic period.

On June 6, 2023, Merck & Co. filed a lawsuit against the HHS and CMS asserting that, among other things, the IRA’s Medicare Drug Price Negotiation Program constitutes an uncompensated taking in violation of the Fifth Amendment of the Constitution. Subsequently, a number of other parties, including the U.S. Chamber of Commerce, Bristol Myers Squibb Company, the PhRMA, Astellas Pharma US, Inc., Novo Nordisk Inc., Janssen Pharmaceuticals, Inc., Novartis Pharmaceutical Corporation, AstraZeneca L.P. and Boehringer Ingelheim Pharmaceuticals, Inc., also filed lawsuits in various courts with similar constitutional claims against the HHS and CMS. HHS has generally won the substantive disputes in these cases, and various federal district court judges have expressed skepticism regarding the merits of the legal arguments being pursued by the pharmaceutical industry. Certain of these cases are now on appeal.

For example, under the GDPR, companies may face temporary or definitive bans on data processing and other corrective actions, as well as fines of up to 20 million euros under the EU GDPR, 17.5 million pounds sterling under the U.K. GDPR, or, in each case, 4% of annual global revenue, whichever is greater. Further, individuals may initiate litigation related to our processing of their personal data. Additionally, under various privacy laws and other obligations, we may be required to obtain certain consents to process personal data. Our inability or failure to do so could result in adverse consequences.

Previous report

In the ordinary course of business, we may transfer personal data from Europe and other jurisdictions to the U.S. or other countries. The European Economic Area (EEA), the United Kingdom (U.K.) and certain jurisdictions have enacted data localization laws and cross-border personal data transfer laws. In particular, the EEA and the U.K. have significantly restricted the transfer of personal data to the U.S. and other countries whose privacy laws it believes are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the EEA and U.K. to the U.S. in compliance with law, such as the EEA standard contractual clauses, the U.K. International Data Transfer Agreement and the EU-U.S. Data Privacy Framework (which allows for transfers for relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the U.S.

Previous report

If there is no lawful manner for us to transfer personal data from the EEA, the U.K. or other jurisdictions to the U.S., or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and U.K. to other jurisdictions, particularly to the U.S., are subject to increased scrutiny from regulators, individual litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the EU GDPR’s cross-border data transfer limitations.

In the EU, a “conditional” marketing authorization may be granted in cases where all the required safety and efficacy data are not yet available. A conditional marketing authorization is subject to conditions to be fulfilled for generating missing data or ensuring increased safety measures. A conditional marketing authorization is valid for one year and has to be renewed annually until fulfillment of all relevant conditions.

Previous report

Once the applicable pending studies are provided, a conditional marketing authorization can become a “standard” marketing authorization. However, if the conditions are not fulfilled within the timeframe set by the EMA, the marketing authorization will cease to be renewed.

In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted relating to non-patent exclusivity. For instance, the EU pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical Strategy for Europe initiative, launched by the European Commission in November 2020. The European Commission’s proposal for revision of several legislative instruments related to medicinal products, which may reduce the duration of regulatory data protection and exclusivity periods for orphan drugs, and revise the eligibility for expedited pathways in addition to other changes, was published on April 26, 2023. On April 10, 2024, the European Parliament adopted a position on the proposal requesting several amendments to the package. The proposed revisions remain to be agreed and adopted by the European Parliament and European Council and the proposals may therefore be substantially revised before adoption, which is not anticipated before early 2026. The revisions may, however, have a significant impact on the pharmaceutical industry and our business in the long term.

Additionally, we could face heightened risks with respect to obtaining marketing authorization in the U.K. as a result of the withdrawal of the U.K. from the EU, commonly referred to as Brexit. The U.K. is no longer part of the European Single Market and EU Customs Union. As of January 1, 2021, the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) became responsible for supervising medicines and medical devices in Great Britain, comprising England, Scotland and Wales under domestic law, whereas under the terms of the Northern Ireland Protocol, Northern Ireland is currently subject to EU rules.

Previous report

The U.K. and the EU have, however, agreed to the Windsor Framework, which fundamentally changes the existing system under the Northern Ireland Protocol, including with respect to the regulation of medicinal products in the U.K. As of January 1, 2025, the changes introduced by the Windsor Framework will see the MHRA be responsible for approving all medicinal products destined for the U.K. market (i.e., Great Britain and Northern Ireland), and the EMA will no longer have any role in approving medicinal products destined for Northern Ireland. Any delay in obtaining, or an inability to obtain, any marketing authorizations, as a result of Brexit or otherwise, may force us to restrict or delay efforts to seek regulatory approval in the U.K. for our product candidates, which could harm our business.

Differences between preliminary, initial or interim results and final results could lead to significantly different interpretations or conclusions of the trial outcomes. Further, others, including regulatory authorities and collaboration or regional partners, 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 our product candidates, the approvability or commercialization of our product candidates, and our business, in general. In addition, the information we choose to publicly disclose regarding a particular clinical trial is based on what is typically extensive information, and investors may not agree with what we determine is material or otherwise appropriate information to publicly disclose.

If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could face significant consequences. These consequences may include, but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation, including class-related claims, and mass arbitration demands; additional reporting requirements and oversight; bans on processing personal data; and orders to destroy or not use personal data.

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 U.S. or the applicable jurisdiction.

In addition, if we are required to change third-party manufacturers for any reason, we will be required to verify that the new third-party manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidates according to the specifications previously submitted to the FDA or another regulatory authority.

For instance, these licenses may not provide exclusive rights to use the subject intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and our product candidates in the future, such as provisions under the license agreement with CRH prohibiting us from developing our product candidates for oncology indications, or provisions under the Mabworks Agreement prohibiting us from undertaking certain activities in Greater China. In that event, we may be required to expend significant time and resources to redesign our technology or the methods for manufacturing or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis.

Current report — wording carried from elsewhere

For example, under the Mabworks Agreement, Mabworks is responsible for prosecuting and maintaining intellectual property protection for CLYM116 in Greater China in consultation with us. We have not had and do not have primary control over these activities in Greater China for CLYM116.

Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner. Any of the foregoing could impair our competitive position and harm our business.

Current report — wording carried from elsewhere

Patent applications in the U.S. and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering budoprutug, CLYM116 or any other product candidates could have been filed by third parties without our knowledge. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover budoprutug, CLYM116 or any other product candidates or their use.

Current report — wording carried from elsewhere

We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business and could harm our business.

We may expend significant resources or modify our business activities, including future clinical trial activities, to protect against security incidents. Certain data privacy and security obligations may require us to implement and maintain specific security measures, industry-standard or reasonable security measures to protect our information technology systems and data. While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective.

In the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology companies following periods of volatility in the market prices of these companies’ stock, in particular following significant drops in stock price. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources from our business.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware and, to the extent enforceable, the federal district courts of the United States of America as the exclusive forums for substantially all disputes between us and our stockholders. These provisions may restrict our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, or employees, and may discourage lawsuits or increase costs if a court finds such provisions unenforceable.

Further, there are several factors that could contribute to making the actual number of patients who receive our product candidates less than the potentially addressable market. These include the lack of widespread availability of, and limited reimbursement for, new therapies in many underdeveloped markets.

Among other things, the IRA contains many provisions aimed at reducing this financial burden on individuals by reducing the co-insurance and co-payment costs, expanding eligibility for lower income subsidy plans, and price caps on annual out-of-pocket expenses, each of which could have potential pricing and reporting implications. Accordingly, while it is currently unclear how the IRA will be effectuated, we cannot predict with certainty what impact any federal or state health reforms will have on us, but such changes could impose new or more stringent regulatory requirements on our activities or result in reduced reimbursement for our product candidates, if and when approved, or any products we may develop, any of which could adversely affect our business, results of operations and financial condition.

While these guidances are currently only in draft form and will ultimately not be legally binding even when finalized, we will need to observe the FDA’s guidance closely if we seek accelerated approval for any of our product candidates. Accordingly, even if we do receive accelerated approval, we may not experience a faster development or regulatory review or approval process, and receiving accelerated approval does not provide assurance of ultimate full FDA approval.

Moreover, these agreements might terminate for various reasons, including a failure to perform by the third parties; if we need to enter into alternative arrangements, that will delay our product development activities and harm our business.

Previous report — wording carried elsewhere

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 studies and clinical trials is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on CROs does not relieve us of our regulatory responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial and for ensuring that our preclinical studies are conducted in accordance with good laboratory practice (GLP) as appropriate.

Previous report — wording carried elsewhere

If we or any of our CROs fail to comply with applicable GCPs, we or our CROs 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 are dependent on third parties for the supply of various materials that are necessary to produce our product candidates for our clinical trials and do not have any supply agreements currently in place. Even if we had supply agreements, it is possible that the supply may be reduced or interrupted at any time. In such case, we may not be able to find other suppliers of acceptable materials in appropriate quantities at an acceptable cost.

We face significant competition in seeking appropriate collaborators, and many more established companies may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, financial resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors.

Previous report — wording carried elsewhere

In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators.

If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.
