Drug candidates that we develop with our partners or on our own may not receive regulatory approval.

The development and commercialization of drug candidates with our partners and through our own internal drug discovery efforts are subject to regulation. Pharmaceutical products require lengthy and costly testing in animals and humans and regulatory approval by governmental agencies prior to commercialization. It takes several years to complete testing and failure can occur at any stage of the testing. Results attained in preclinical testing and early clinical trials for any of our drug candidates may not be indicative of results that are obtained in later studies and significant setbacks in advanced clinical trials may arise, even after promising results in earlier studies. Clinical trials may not demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals or result in marketable products. Furthermore, data obtained from preclinical and clinical studies are susceptible to varying interpretations that may delay, limit or prevent regulatory approval. For example, following our submission of NDAs for binimetinib and encorafinib in BRAF-mutant melonoma, we continue to work with the FDA as they review the submissions. We may also experience other delays in obtaining regulatory review or approval or receive a determination from the FDA not to approve binimetinib in this indication. For a drug candidate that requires a companion diagnostic test, we may not be able to obtain approval for the drug if the FDA does not approve or clear its corresponding companion diagnostic test. In addition, the administration of any drug candidate we develop may produce undesirable side effects or safety issues that could result in the interruption, delay or suspension of clinical trials, or the failure to obtain FDA or other regulatory approval for any or all targeted indications. Based on results at any stage of testing, we or our partners may decide to repeat or redesign a trial or discontinue development of a drug candidate.

Approval of a drug candidate as safe and effective for use in humans is never certain and regulatory agencies may delay or deny approval of drug candidates for commercialization. These agencies may also delay or deny approval based on additional government regulation or administrative action, changes in regulatory policy during the period of clinical trials in humans and regulatory review, or the availability of alternative treatments. None of our partners has obtained regulatory approval to manufacture and sell drug candidates owned by us or identified or developed under an agreement with us. If we or our partners cannot obtain this approval, we will not realize milestone or royalty payments based on commercialization goals for these drug candidates.

Delays or failures in validating, developing and obtaining regulatory approval for the BRAF-mutant melanoma companion diagnostic test could harm the prospects for approval and commercialization of binimetinib for BRAF-mutant melanoma.

We are developing a BRAF melanoma companion diagnostic test for use with our product candidate binimetinb for BRAF-mutant melanoma. Companion diagnostics typically are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and require separate regulatory approval prior to commercialization. We may encounter difficulties in developing and obtaining approval for the BRAF melanoma companion diagnostic test, including, but not limited to, issues related to selectivity/specificity, analytical validation, reproducibility, or clinical validation. Any delay or failure by us to develop or obtain regulatory approval of the companion diagnostic test could delay or prevent approval of our product candidate binimetinib. Even if we obtain approval of the companion diagnostic test and transfers the test to a vendor of our designation, that vendor may encounter production difficulties that could constrain the supply of the companion diagnostic. The vendor and/or we also may have difficulties gaining acceptance of the use of the companion diagnostic in the clinical community. If the companion diagnostic fails to gain market acceptance, it could have an adverse effect on our ability to derive revenues from sales of our product candidate binimetinib, if approved, for use in BRAF-mutant melanoma. In addition, the vendor we designate could decide to discontinue selling or manufacturing the companion diagnostic or our relationship with such vendor may otherwise terminate. We may be delayed in identifying another vendor, or we may not be able to enter into arrangements with another vendor to maintain supply of the companion diagnostic, which could adversely affect our commercialization of binimetinib for BRAF-mutant melanoma, if it is approved for that use.

Even if our drug candidates obtain regulatory approval, we and our partners will be subject to ongoing government regulation, including federal and state fraud and abuse laws, such as anti-kickback and false claims laws.

Even if regulatory authorities approve any of our drug candidates, the manufacture, labeling, storage, recordkeeping, reporting, distribution, advertising, promotion, marketing, sale, import and export of these drugs will be subject to strict and ongoing regulation. If we, our partners, our product candidates or the manufacturing facilities for our product candidates fail to comply with applicable regulatory requirements, a regulatory agency may suspend any ongoing
