Molecular Partners AG (MLLCF) Risk Analysis

Undesirable side effects that may be caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, the EMA or other comparable foreign authorities. While our preclinical studies and clinical trials for our product candidates to date have generally been well tolerated from a risk-benefit perspective, the results from ongoing and future trials may not support this conclusion. The results of future clinical studies may show that our product candidates cause undesirable or unacceptable side effects or even death. In such an event, our trials could be suspended or terminated and the FDA, the EMA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our prospects significantly. Further, because all of our product candidates and preclinical programs are based on our DARPin technology, any adverse safety or efficacy findings related to any product candidate or preclinical program may adversely impact the viability of our other product candidates or preclinical programs. Additionally, if any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products, a number of potentially significant negative consequences could result, including: - regulatory authorities may withdraw approvals of such products and require us to take our approved product off the market;- regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and pharmacies;- regulatory authorities may require a medication guide outlining the risks of such side effects for distribution to patients, or that we implement a risk evaluation and mitigation strategy, or REMS, plan to ensure that the benefits of the product outweigh its risks;- regulatory authorities may require additional clinical trials;- we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product;- sales of the product may decrease significantly;- we may be subject to litigation or product liability claims; and - our reputation may suffer. Any of these events could prevent us, our collaborators or our potential future partners from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from the sale of our products.

Our commercial success depends in part on obtaining and maintaining patents and other forms of intellectual property rights for our product candidates, methods used to manufacture those products and methods for treating patients using those products, or on licensing in such rights. Failure to obtain, maintain, enforce, protect or extend adequate patent and other intellectual property rights could adversely affect our ability to develop and market our products and product candidates or pursue collaborations with partners for our product candidates. We cannot be certain that patents will be issued or granted with respect to applications that are currently pending, or that issued or granted patents will not later be found to be invalid or unenforceable. The patent position of biopharmaceutical companies is generally uncertain because it involves complex legal and factual considerations, and has been the subject of much litigation in recent years. The standards applied by the United States Patent and Trademark Office, or USPTO, the European Patent Office, or EPO, and other foreign patent offices in granting patents are not always identical or applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in biopharmaceutical patents. Consequently, patents may not issue from our pending patent applications or, if issued, patents may vary in scope depending on the jurisdiction. As such, we do not know the degree of future protection that we will have on our proprietary products and technology in the various jurisdictions. The scope of patent protection that the USPTO, the EPO and other foreign patent offices will grant with respect to the DARPin product candidates in our product pipeline is uncertain. It is possible that the USPTO, the EPO and other foreign patent offices will not allow broad claims that cover DARPin product candidates closely related to our product candidates or to the specific protein building blocks. As a result, upon receipt of EMA or FDA approval, competitors may be free to market other products almost identical to ours, thereby decreasing our market share. The patent prosecution process is expensive, time-consuming and complex, and we and our current or future licensors, licensees or collaboration partners may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our licensors, licensees or collaboration partners will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection for them. Although we enter into non-disclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, collaborators, CROs, contract manufacturers, consultants, advisors and other third parties, any of these parties may breach the agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. Further, the issuance, scope, validity, enforceability and commercial value of our and our current or future licensors', licensees' or collaboration partners' patent rights are highly uncertain. Our and our licensors' pending and future patent applications may not result in patents being issued that protect our technology or products, in whole or in part, or that effectively prevent others from commercializing competitive technologies and products. Moreover, in some circumstances, we may not have the right to control the preparation, filing, prosecution and maintenance of the licensed patent applications or other intellectual property, or to maintain the patents, or may not have the first right to enforce the intellectual property. We may need to enter into new license or royalty agreements, covering technology that we license from or license to third parties or have developed in collaboration with our collaboration partners and are reliant on patent procurement activities of our licensors, licensees or collaboration partners. Therefore, we may not be able to adequately influence the patent prosecution or enforcement of these patents and patent applications, or prevent inadvertent lapses of coverage due to failure to pay maintenance fees and we cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced and defended in a manner consistent with the best interests of our business and that does not compromise the patent rights. If our current or future licensors, licensees or collaboration partners fail to obtain, maintain, protect or enforce such patents and other intellectual property rights, such rights may be reduced or lost. If our licensors, licensees or collaboration partners are not fully cooperative or disagree with us as to the preparation, filing, prosecution, maintenance, defense or enforcement of any licensed patent rights, such patent rights could be compromised. The patent examination process may require us or our licensors, licensees or collaboration partners to narrow the scope of the claims of our or our licensors', licensees' or collaboration partners' pending and future patent applications, which may limit the scope of patent protection that may be obtained. We cannot assure you that all of the potentially relevant prior art relating to our patents and patent applications has been found. If such prior art exists, it may invalidate patents in whole or in part or prevent patents from issuing from pending patent applications. Even if patents do successfully issue and even if such patents cover our product candidates, third parties may initiate an opposition, interference, re-examination, post-grant review, inter partes review, nullification, revocation, derivation, or other actions in court or before patent offices challenging the validity, enforceability or scope of such patents, which may result in the patent claims being narrowed, invalidated, or held unenforceable. Such proceedings have a higher impact in the biopharmaceutical industry than in other industries, given that biopharmaceutical products are often protected by only one or few patents. Our and our licensors', licensees' or collaboration partners' patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications, and then only to the extent the issued claims cover the practiced technology. An adverse determination in any such proceeding could reduce the scope of, invalidate, or render unenforceable our patent rights, and allow third parties to commercialize our technology or products and compete directly with us, without payment to us. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability. Even if our patent applications or those of our licensors, licensees or collaboration partners issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Any patents may be challenged, narrowed, circumvented or invalidated by third parties. Consequently, we do not know whether any of our DARPin platform advances or product candidates will be protectable or remain protected by valid and enforceable patents. In addition, 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. In addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications are confidential for a period of time after filing, and some remain so until issued. Therefore, we cannot be certain that we or our licensors, licensees or collaborators were the first to make the inventions claimed in any patent application, or were the first to file any patent application related to a product candidate. Furthermore, as to the United States, if third parties have filed such patent applications on or before March 15, 2013, an interference proceeding can be initiated by such third parties to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. If third parties have filed such applications after March 15, 2013, a derivation proceeding can be initiated by such third parties to determine whether our invention was derived from theirs. Even where we have a valid and enforceable patent, we may not be able to exclude others from practicing our invention where the other party can show that they used the invention in commerce before our filing date, or if the other party is able to obtain a compulsory license. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such product candidates are commercialized. As a result, our intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours, including generic versions of such products. Moreover, it is possible that some future patents and patent applications owned or in-licensed by us may be co-owned with third parties, including our collaboration partners and other third parties with whom we conduct research and development. If we are unable to obtain an exclusive license to any such third party co-owners' interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we may need the cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us. Furthermore, it is possible that some future patents and patent applications owned or in-licensed by us may be subject to a reservation of rights by one or more third parties. For example, this may happen if the research resulting in certain of our owned or in-licensed patent rights and technology was funded in part by the U.S. government. As a result, the government may have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention for noncommercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow third parties to use our licensed technology. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

In the United States, the European Union and other foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, became law. The ACA is a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. There have been executive, judicial and Congressional challenges and amendments to certain aspects of the ACA. For example, on August 16, 2022, the Inflation Reduction Act of 2022, or IRA, was signed into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the "donut hole" under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. 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 new administration will impact the ACA and our business. In addition, other legislative changes have been proposed and adopted since the ACA was enacted. For example, on August 2, 2011, the Budget Control Act of 2011, among other things, includes aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute will remain in effect until 2032 unless additional U.S. Congressional action is taken. Additionally, on March 11, 2021, the American Rescue Plan Act of 2021 was signed into law, which eliminated the statutory Medicaid drug rebate cap, previously set at 100% of a drug's average manufacturer price, for single source and innovator multiple source drugs, effective January 1, 2024. Recently there has also been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. Specifically, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for drugs. For example, the IRA, among other things (i) directs the U.S. Department of Health and Human Services ("HHS") to negotiate the price of certain high-expenditure, single-source biologics that have been on the market for 11 years covered under Medicare (the "Medicare Drug Price Negotiation Program") and (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions began to take effect progressively in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon price of the first ten drugs that were subject to price negotiations, although the Medicare Drug Price Negotiation Program is currently subject to legal challenges. On January 17, 2025, HHS selected fifteen additional products covered under Part D for price negotiation in 2025. Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price Negotiation Program. Further, on December 7, 2023, an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act was announced. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework. It is unclear whether these or similar policy initiatives will be implemented in the future. In addition, Congress is considering additional health reform measures. At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our products or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition and prospects. We expect that additional U.S. federal healthcare reform measures will be adopted in the future, particularly in light of the recent U.S. Presidential and Congressional elections, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. In the European Union, similar political, economic and regulatory developments may affect our ability to profitably commercialize our current or any future products. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles that may increase our operating costs. The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize any products for which we obtain marketing approval. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. 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 in other countries. If we or our collaborators are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our business.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing and use of pharmaceutical products. Currently, we have no products that have been approved for commercial sale; however, the current and future use of product candidates by us and our corporate collaborators in clinical trials, and the potential sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients who use the product, healthcare providers, pharmaceutical companies, our corporate collaborators or others selling such products. Any claims against us, regardless of their merit, could be difficult and costly to defend and could adversely affect the market for our product candidates or any prospects for commercialization of our product candidates. Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval, may exhibit unforeseen side effects. If any of our product candidates were to cause adverse side effects during clinical trials or after approval of the product candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse effects and patients who should not use our product candidates. Regardless of the merits or eventual outcome, liability claims may result in: - decreased demand for our products due to negative public perception and injury to our reputation;- withdrawal of clinical trial participants or difficulties in recruiting new trial participants;- initiation of investigations by regulators;- costs to defend or settle the related litigation;- a diversion of management's time and our resources;- substantial monetary awards to trial participants or patients;- product recalls, withdrawals or labeling, marketing or promotional restrictions;- loss of revenues from product sales; and - the inability to commercialize any of our product candidates, if approved. Although we maintain adequate clinical trial insurance for our product candidates, it is possible that our liabilities could exceed our insurance coverage. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for any of our product candidates. However, we may not be able to maintain insurance coverage at a reasonable cost or obtain insurance coverage that will be adequate to satisfy any liability that may arise. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired. Should any of the events described above occur, this could have an adverse effect on our business and results of operations.

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, and accept payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies 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, over the last several years, the U.S. government has shut down several times, and certain regulatory agencies, such as the FDA, have had to furlough critical FDA and other government employees and stop critical activities. If a prolonged government shutdown occurs, it 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, in our operations as a public company, 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.

We do not and will not have access to all information regarding the product candidates being developed and potentially commercialized by Novartis under our collaboration, including potentially material information about clinical trial design and execution, safety reports from clinical trials, spontaneous safety reports if the product is later approved and marketed, regulatory affairs, process development, manufacturing, marketing and other areas known by Novartis. In addition, we have confidentiality obligations under our agreement with Novartis. Thus, our ability to keep our shareholders informed about the status of product candidates under our collaboration will be limited by the degree to which Novartis keeps us informed and allows us to disclose such information to the public.

Our success depends upon the continued contributions of our key management, scientific and technical personnel, many of whom have been instrumental for us and have substantial experience with our therapies and related technologies. These key management individuals include the members of our board of directors and executive management, including Dr. Patrick Amstutz, our Chief Executive Officer, Dr. Alexander Zürcher, our Chief Operating Officer, Dr. Michael Tobias Stumpp, our EVP Projects, Dr. Philippe Legenne, our Chief Medical Officer and Renate Gloggner, our EVP People and Culture. The loss of key managers and senior scientists could delay our research and development activities. In addition, our ability to compete in the highly competitive biotechnology and pharmaceutical industries, and particularly, in the oncology field, depends upon our ability to attract and retain highly qualified management, scientific and medical personnel. Many other biotechnology and pharmaceutical companies and academic institutions that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. Therefore, we might not be able to attract or retain these key persons on conditions that are economically acceptable. Furthermore, we will need to recruit new managers and qualified scientific personnel to develop our business if we expand into fields that will require additional skills. Additionally, there is a larger pool of qualified scientific and medical personnel in the United States than in Switzerland, and we may need to increase our presence in the United States in order to attract and retain the necessary human resources. Our inability to attract and retain these key persons could prevent us from achieving our objectives and implementing our business strategy, which could have an adverse effect on our business and prospects.

We rely on our licensees to manufacture, fund and conduct the clinical development and commercialization of product candidates, and our licensees have complete control over such activities. Our ability to generate revenue in the near term will depend primarily on the successful development, regulatory approval, marketing and commercialization of product candidates by our licensees. Such success is subject to significant uncertainty, and we have limited control over the manufacturing processes of such product candidates as well as the resources, time and effort that licensees may devote to such product candidates. Any of several events or factors could have a material adverse effect on our ability to generate revenue from our licensee's potential commercialization of product candidates. In addition, our licensees have the right to make decisions regarding the development and commercialization of product candidates under the collaborations without consulting us and may make decisions with which we do not agree. For example in January 2024, Novartis, our collaboration partner for ensovibep, informed us of its decision to return the global rights for ensovibep to us following the end of COVID-19 pandemic. Conflicts between our licensees and us may arise if there is a dispute about the progress of the clinical development of a product candidate, the achievement and payment of a milestone amount or the ownership of intellectual property developed during the course of our collaboration agreements. If any of our licenses terminate with our licensees, it may be necessary for us to assume responsibility at our own expense for the development of the applicable product candidates. In that event, we would likely be required to limit the size and scope of one or more of our programs or increase our expenditures and seek additional funding, which may not be available on acceptable terms or at all, which would materially adversely affect our business, financial condition and results of operations.

The market for pharmaceutical products is highly competitive. Our competitors include many established pharmaceutical companies, biotechnology companies, universities and other research or commercial institutions, many of which have substantially greater financial, research and development resources than us. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. Smaller and early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, the development of our products. The fields in which we operate are characterized by rapid technological change and innovation. There can be no assurance that our competitors are not currently developing, or will not in the future develop, technologies and products that are equally or more effective or are more economically attractive as any of our current or future technology or product. Competing products or platforms may gain faster or greater market acceptance than our products or platform and medical advances or rapid technological development by competitors may result in our product candidates or platforms becoming non-competitive or obsolete before we are able to recover our research and development and commercialization expenses. Additionally, certain of our product candidates may be administered in combination with approved pharmaceutical products. Our ability to develop and ultimately commercialize our product candidates used in combination with other therapies will depend on our ability to access these drugs on commercially reasonable terms for the clinical trials and their availability for use with the commercialized product, if approved. We cannot be certain that current or potential future commercial relationships will provide us with a sufficient supply of these drugs on commercially reasonable terms or at all. If we, our product candidates or our platforms do not compete effectively, it may have an adverse effect on our business and results of operation.

Our product candidates are at varying stages of development and we may never have a product that is commercially successful. To date, we have no product authorized for marketing. Our lead product candidates are in the relatively early stages of clinical development. Our lead product candidates will require further clinical investigation, regulatory review, significant marketing efforts and substantial investment before they can provide us with any revenues. Furthermore, if and when available on the market, our products may not achieve an adequate level of acceptance by physicians, patients and the medical community, and we may not become profitable. If our products are not accepted, we may need to increase our efforts to educate the medical community and third-party payors on the benefits of our products, which may require significant resources and may never be successful. Market acceptance of our future products by physicians, patients and healthcare payors will depend on a number of factors, many of which are beyond our control, including: - the wording of the product label;- changes in the standard of care as well as recommendations from relevant national and/or international associations for the targeted indications for any product candidate;- sales, marketing and distribution support;- potential product liability claims;- acceptance by physicians, patients and healthcare payors of each product as safe and effective;- relative convenience, ease of use, ease of administration and other perceived advantages over alternative products;- availability of coverage and adequate reimbursement from third-party payors and the willingness of patients to pay out-of-pocket in the absence of adequate reimbursement;- prevalence and severity of adverse events or publicity;- limitations, precautions or warnings listed in the summary of product characteristics, patient information leaflet, package labeling or instructions for use;- the cost of treatment with our products in relation to alternative treatments;- the extent to which products are approved for inclusion and reimbursed on formularies of hospitals and managed care organizations; and - whether our products are designated in the label, under physician treatment guidelines or under reimbursement guidelines as a first-line, second-line, third-line or last-line therapy. If our product candidates fail to gain market acceptance, this will have a material adverse impact on our ability to generate revenues to provide a satisfactory, or any, return on our investments. Even if a potential product displays a favorable efficacy and safety profile in preclinical studies and clinical trials, market acceptance of the product will not be fully known until after it is launched. Furthermore, even if some products achieve market acceptance, the market may prove not to be large enough to allow us to generate significant revenues.

Adverse side effects that may be caused by any of our product candidates could negatively impact the public perception of and commercial opportunities for all of our product candidates. The clinical and commercial success of our product candidates will depend in part on the absence of negative side effects caused by our product candidates. Even if an adverse side effect that results from one of our product candidates is unlikely to occur in our other product candidates, all of our product candidates could be adversely affected because the negative side effect may be perceived to be a likely side effect of all of our product candidates. Infusion-related reactions have been seen in MP0533 and MP0317, and, while manageable, such reactions may limit the tolerability profile of a product candidate or its potential for combination with other medication. These adverse events may negatively affect the perception of the DARPin platform, the commercial opportunity for our product candidates or cause us to suspend clinical trials. In addition, if public perception is influenced by claims that radioligands or specific therapies within radioligands are unsafe or less safe than available alternatives, our product candidates may not be accepted by the general public or the medical community.

Due to the international scope of our operations, our assets, earnings and cash flows are influenced by movements in exchange rates of several currencies, particularly the euro, U.S. dollar and Swiss franc. Our functional currency is the Swiss franc, and the majority of our operating expenses are paid in Swiss franc, but we also receive or may receive payments from business partners in U.S. dollars, and we regularly acquire services, consumables and materials in U.S. dollars and euros. Further, potential future revenue may be derived from abroad, particularly from the United States or the European Union. As a result, our business and the price of our ADSs and ordinary shares may be affected by fluctuations in foreign exchange rates between the Swiss franc and these other currencies, which may also have a significant impact on our reported results of operations and cash flows from period to period. Besides natural hedging, currently, we do not have any exchange rate hedging arrangements in place. Moreover, because our ordinary shares currently trade on the SIX Swiss Exchange in Swiss francs, and our ADSs trade on the Nasdaq Global Select Market in U.S. dollars, fluctuations in the exchange rate between the U.S. dollar and the Swiss franc may result in temporary differences between the value of our ADSs and the value of our ordinary shares, which may result in heavy trading by investors seeking to exploit such differences.
