Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Leases We have operating leases for our corporate headquarters in Alameda, California and in Greater Philadelphia area which includes both office and laboratory space totaling approximately 674,000 square feet with lease terms ending in 2025 through 2037. Certain of our leases include options to renew the lease or to early terminate the lease. As of December 31, 2024, we considered whether these options to renew or early terminate were reasonably certain of exercise in determining the related lease terms. Impairment of Long-Lived Assets In connection with our 2024 Restructuring Plan, as discussed in “Note 13. Restructuring”, we exited two leases in the Greater Philadelphia area pertaining to approximately 40,000 square feet of leased premises and performed an impairment analysis for these asset groups, primarily composed of right-of-use assets, leasehold improvements, and certain property and equipment. We reassessed the lease term for one of the leases in the Greater Philadelphia area and concluded we were reasonably certain to exercise our right to early terminate the lease and reduced our right-of-use asset and lease liability by $3.3 million. In connection with the restructuring plan, we recognized $12.7 million of non-cash impairment charge during the year ended December 31, 2024, to reduce the carrying value of these long-lived assets at their fair value. The impairment charge is presented in restructuring in the accompanying Consolidated Statements of Income. During fiscal 2024, we evaluated our plans for the Alameda leased facilities and listed certain buildings for sublease. As a result, we determined the related right-of-use assets and leasehold improvements should be evaluated for impairment as separate asset groups. We concluded that these asset groups were not recoverable and we recognized $51.7 million of non-cash impairment charge and reduced the carrying value of our right-of-use assets pertaining to approximately 215,000 square feet of leased premises, reduced the leasehold improvements and certain property and equipment, to their estimated fair value. The estimated fair value was determined using an income approach comprised of projected discounted cash flows that included certain Level 3 inputs, such as sublease income and discount rates. The assumptions associated with sublease income and discount rates are subject to risks and uncertainties and could materially differ from our estimates. The impairment charge is presented in impairment of long-lived assets in the accompanying Consolidated Statements of Income.

Legal Proceedings MSN I ANDA Litigation In September 2019, we received a notice letter regarding an Abbreviated New Drug Application (ANDA) submitted to the FDA by MSN Pharmaceuticals, Inc. (individually and collectively with certain of its affiliates, including MSN Laboratories Private Limited, referred to as MSN), requesting approval to market a generic version of CABOMETYX tablets. MSN’s initial notice letter included a Paragraph IV certification with respect to our U.S. Patents No. 8,877,776 (salt and polymorphic forms), 9,724,342 (formulations), 10,034,873 (methods of treatment) and 10,039,757 (methods of treatment), which are listed in the Approved Drug Products with Therapeutic Equivalence Evaluations, also referred to as the Orange Book, for CABOMETYX. MSN’s initial notice letter did not provide a Paragraph IV certification against U.S. Patents No. 7,579,473 (composition of matter) or 8,497,284 (methods of treatment), each of which is listed in the Orange Book. On October 29, 2019, we filed a complaint in the United States District Court for the District of Delaware (the Delaware District Court) for patent infringement against MSN asserting infringement of U.S. Patent No. 8,877,776 arising from MSN’s ANDA filing with the FDA. On November 20, 2019, MSN filed its response to the complaint, alleging that the asserted claims of U.S. Patent No. 8,877,776 are invalid and not infringed. On May 5, 2020, we received notice from MSN that it had amended its ANDA to include additional Paragraph IV certifications. In particular, the May 5, 2020 amended ANDA requested approval to market a generic version of CABOMETYX tablets prior to expiration of two previously unasserted CABOMETYX patents: U.S. Patents No. 7,579,473 and 8,497,284. On May 11, 2020, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patents No. 7,579,473 and 8,497,284 arising from MSN’s amended ANDA filing with the FDA. Neither of our complaints have alleged infringement of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757. On May 22, 2020, MSN filed its response to the complaint, alleging that the asserted claims of U.S. Patents No. 7,579,473 and 8,497,284 are invalid and not infringed. On March 23, 2021, MSN filed its First Amended Answer and Counterclaims (amending its prior filing from May 22, 2020), seeking, among other things, a declaratory judgment that U.S. Patent No. 9,809,549 (salt and polymorphic forms) is invalid and would not be infringed by MSN if its generic version of CABOMETYX tablets were approved by the FDA. U.S. Patent No. 9,809,549 is not listed in the Orange Book. On April 7, 2021, we filed our response to MSN’s First Amended Answer and Counterclaims, denying, among other things, that U.S. Patent No. 9,809,549 is invalid or would not be infringed. The two lawsuits comprising this litigation (collectively referred to as MSN I), numbered Civil Action Nos. 19-02017 and 20-00633, were consolidated in April 2021. On October 1, 2021, pursuant to a stipulation between us and MSN, the Delaware District Court entered an order that (i) MSN’s submission of its ANDA constitutes infringement of certain claims relating to U.S. Patents No. 7,579,473 and 8,497,284, if those claims are not found to be invalid, and (ii) upon approval, MSN’s commercial manufacture, use, sale or offer for sale within the U.S., and importation into the U.S., of MSN’s proposed ANDA product prior to the expiration of U.S. Patents No. 7,579,473 and 8,497,284 would also infringe certain claims of each patent, if those claims are not found to be invalid. Then, on October 12, 2021, pursuant to a separate stipulation between us and MSN, the Delaware District Court entered an order dismissing MSN’s counterclaim with respect to U.S. Patent No. 9,809,549. In our MSN I complaints, we sought, among other relief, an order that the effective date of any FDA approval of MSN’s ANDA be a date no earlier than the expiration of all of U.S. Patents No. 7,579,473, 8,497,284 and 8,877,776, the latest of which expires on October 8, 2030, and equitable relief enjoining MSN from infringing these patents. To streamline the case, the parties narrowed their assertions. On April 8, 2022, MSN withdrew its validity challenge to U.S. Patent No. 8,877,776. On April 14, 2022, we agreed not to assert U.S. Patent No. 8,497,284 at trial and MSN, correspondingly, agreed to withdraw its validity challenges to U.S. Patent No. 8,497,284, as well as claims 1-4 and 6-7 of U.S. Patent No. 7,579,473. As a result of this narrowing, the trial addressed two issues: (1) infringement of claim 1 of the U.S. Patent No. 8,877,776; and (2) validity of claim 5 of the U.S. Patent No. 7,579,473. A bench trial for MSN I occurred in May 2022, and on January 19, 2023, the Delaware District Court issued a ruling rejecting MSN’s invalidity challenge to U.S. Patent No. 7,759,473. The Delaware District Court also ruled that MSN’s proposed ANDA product does not infringe U.S. Patent No. 8,877,776. In accordance with these rulings, the Delaware District Court entered judgment that the effective date of any final FDA approval of MSN’s ANDA shall not be a date earlier than August 14, 2026, the expiration date of U.S. Patent No. 7,759,473. Final judgment was entered on January 30, 2023. This ruling in MSN I did not impact our separate MSN II lawsuit (as defined below). MSN II ANDA Litigation On January 11, 2022, we received notice from MSN that it had further amended its ANDA to assert additional Paragraph IV certifications. In particular, the January 11, 2022 amended ANDA requested approval to market a generic version of CABOMETYX tablets prior to expiration of three previously-unasserted CABOMETYX patents that are now listed in the Orange Book: U.S. Patents No. 11,091,439 (crystalline salt forms), 11,091,440 (pharmaceutical composition) and 11,098,015 (methods of treatment). On February 23, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 arising from MSN’s further amendment of its ANDA filing with the FDA. On February 25, 2022, MSN filed its response to the complaint, alleging that the asserted claims of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 are invalid and not infringed. On June 7, 2022, we received notice from MSN that it had further amended its ANDA to assert an additional Paragraph IV certification. As currently amended, MSN’s ANDA now requests approval to market a generic version of CABOMETYX tablets prior to expiration of a previously-unasserted CABOMETYX patent that is now listed in the Orange Book: U.S. Patent No. 11,298,349 (pharmaceutical composition). On July 18, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patent No. 11,298,349 arising from MSN’s further amendment of its ANDA filing with the FDA. On August 9, 2022, MSN filed its response to the complaint, alleging that the asserted claims of U.S. Patent No. 11,298,349 are invalid and not infringed and amended its challenges to U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 to allege that these patents are not enforceable based on equitable grounds. The two lawsuits comprising this litigation (collectively referred to as MSN II), numbered Civil Action Nos. 22-00228 and 22-00945, were consolidated in October 2022 and involve Exelixis patents that are different from those asserted in the MSN I litigation described above. On June 21, 2022, pursuant to a stipulation between us and MSN, the Delaware District Court entered an order that (i) MSN’s submission of its ANDA constitutes infringement of certain claims relating to U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015, if those claims are not found to be invalid, and (ii) upon approval, MSN’s commercial manufacture, use, sale or offer for sale within the U.S., and importation into the U.S., of MSN’s proposed ANDA product prior to the expiration of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 would also infringe certain claims of each patent, if those claims are not found to be invalid. In our MSN II complaints, we sought, among other relief, an order that the effective date of any FDA approval of MSN’s ANDA would be a date no earlier than the expiration of all of U.S. Patents No. 11,091,439, 11,091,440, 11,098,015 and 11,298,349, the latest of which expires on February 10, 2032, and equitable relief enjoining MSN from infringing these patents. On September 28, 2023, the Delaware District Court granted the parties’ stipulation of dismissal of MSN’s equitable defenses and counterclaims. A bench trial occurred in October 2023, and on October 15, 2024, the Delaware District Court issued a ruling rejecting MSN’s invalidity challenge to each of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015. The Delaware District Court also ruled that our U.S. Patent No. 11,298,349 is not invalid and that MSN’s proposed ANDA product does not infringe this patent. In accordance with these rulings, the Delaware District Court entered final judgment on October 23, 2024, that, should the FDA ultimately approve MSN’s ANDA, the effective date of any such approval of MSN’s ANDA shall not be a date earlier than January 15, 2030, the expiration date of each of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015, subject to our potential additional regulatory exclusivity. On November 22, 2024, MSN noticed an appeal to the Court of Appeals for the Federal Circuit and we noticed a cross-appeal on November 26, 2024. We are currently evaluating next steps with respect to this litigation. In February 2025, we received another notice letter from MSN regarding its ANDA, requesting FDA approval to market a generic version of CABOMETYX tablets. MSN’s notice letter included a Paragraph IV certification with respect to Orange Book-listed patent U.S. Patent No. 12,128,039 (low impurity), which expires in 2032. We intend to continue to vigorously defend our cabozantinib intellectual property estate. Teva ANDA Litigation In May 2021, we received notice letters regarding an ANDA submitted to the FDA by Teva Pharmaceutical Industries Limited, Teva Pharmaceuticals Development, Inc. and Teva Pharmaceuticals USA, Inc. (individually and collectively referred to as Teva), requesting approval to market a generic version of CABOMETYX tablets. Teva’s notice letters included a Paragraph IV certification with respect to our U.S. Patents No. 9,724,342 (formulations), 10,034,873 (methods of treatment) and 10,039,757 (methods of treatment), which are listed in the Orange Book. Teva’s notice letters did not provide a Paragraph IV certification against any additional CABOMETYX patents. On June 17, 2021, we filed a complaint in the Delaware District Court for patent infringement against Teva asserting infringement of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757 arising from Teva’s ANDA filing with the FDA. On August 27, 2021, Teva filed its answer and counterclaims to the complaint, alleging that the asserted claims of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757 are invalid and not infringed. On September 17, 2021, we filed an answer to Teva’s counterclaims. On July 29, 2022, we received notice from Teva that it had amended its ANDA to assert an additional Paragraph IV certification. As amended, Teva’s ANDA now requests approval to market a generic version of CABOMETYX tablets prior to expiration of a previously-unasserted CABOMETYX patent that is now listed in the Orange Book: U.S. Patent No. 11,298,349 (pharmaceutical composition). On September 2, 2022, we filed a complaint in the Delaware District Court for patent infringement against Teva, asserting infringement of U.S. Patent No. 11,298,349 arising from Teva’s amended ANDA filing with the FDA. We sought, among other relief, an order that the effective date of any FDA approval of Teva’s ANDA be a date no earlier than the expiration of all of U.S. Patents No. 9,724,342, 10,034,873, 10,039,757 and 11,298,349, the latest of which expires on July 9, 2033, and equitable relief enjoining Teva from infringing these patents. On September 30, 2022, the parties filed a stipulation to consolidate the two lawsuits, numbered Civil Action Nos. 21-00871 and 22-01168, and to stay all proceedings, which was granted by the Delaware District Court on October 3, 2022. Following a similar order granted by the Delaware District Court on February 9, 2022 to stay all proceedings with respect to Civil Action No. 21-00871, this case remained administratively closed, and Civil Action No. 22-01168 was administratively closed on October 3, 2022. In July 2023, we entered into a settlement and license agreement with Teva (the Teva Settlement Agreement) to end these litigations. Pursuant to the terms of the Teva Settlement Agreement, we will grant Teva a license to market its generic version of CABOMETYX in the U.S. beginning on January 1, 2031, if approved by the FDA and subject to conditions and exceptions common to agreements of this type. On September 15, 2023, the parties filed a joint stipulation of dismissal with the Delaware District Court, and on September 19, 2023, the Delaware District Court granted the parties’ stipulation and dismissed the case without prejudice. Cipla ANDA Litigation On February 6, 2023, we received a notice letter regarding an ANDA submitted to the FDA by Cipla, Ltd. and Cipla USA, Inc. (individually and collectively referred to as Cipla), including a Paragraph IV certification with respect to our U.S. Patents No. 8,877,776 (salt and polymorphic forms), 9,724,342 (formulations), 10,039,757 (methods of treatment), 11,091,439 (crystalline salt forms), 11,091,440 (pharmaceutical composition), 11,098,015 (methods of treatment) and 11,298,349 (pharmaceutical composition). Cipla’s notice letter did not provide a Paragraph IV certification against any additional CABOMETYX patents. On March 16, 2023, we filed a complaint in the Delaware District Court for patent infringement against Cipla asserting infringement of U.S. Patents No. 8,877,776, 11,091,439, 11,091,440, 11,098,015 and 11,298,349 arising from Cipla’s ANDA filing with the FDA. Cipla’s ANDA requests approval to market a generic version of CABOMETYX tablets prior to the expiration of the aforementioned patents. We sought, among other relief, an order that the effective date of any FDA approval of Cipla’s ANDA would be a date no earlier than the expiration of all of U.S. Patents No. 8,877,776, 11,091,439, 11,091,440, 11,098,015 and 11,298,349, the latest of which expires on February 10, 2032, and equitable relief enjoining Cipla from infringing these patents. On May 4, 2023, we filed, under seal, a stipulation and proposed order to stay all proceedings, and the Delaware District Court, in a sealed order on the same day, granted the proposed order and administratively closed the case. On May 5, 2023, the Delaware District Court issued a redacted version of the May 4, 2023 stipulation and proposed order. On March 27, 2024, we received notice from Cipla that it had amended its ANDA to assert additional Paragraph IV certifications. The ANDA now requests approval to market generic versions of CABOMETYX tablets with 20 mg and 40 mg dosage strengths (in addition to the 60 mg dosage strength contemplated by Cipla’s original ANDA) prior to expiration of U.S. Patents No. 8,877,776, 9,724,342, 10,039,757, 11,091,439, 11,091,440, 11,098,015 and 11,298,349. In May 2024, we entered into a settlement and license agreement (the Cipla Settlement Agreement) with Cipla to end these litigations. Pursuant to the terms of the Cipla Settlement Agreement, we granted Cipla a license to market its generic version of CABOMETYX in the U.S. beginning on January 1, 2031, if approved by the FDA and subject to conditions and exceptions common to agreements of this type. On July 8, 2024, the parties filed a joint stipulation of dismissal with the Delaware District Court, and on July 9, 2024, the Delaware District Court granted the parties’ stipulation and dismissed the case without prejudice. Sun ANDA Litigation On September 17, 2024, we received a notice letter regarding an ANDA submitted to the FDA by Sun Pharmaceutical Industries Ltd. (Sun), requesting approval to market a generic version of CABOMETYX tablets. Sun’s notice letter included a Paragraph IV certification with respect to our U.S. Patents No. 8,877,776 (salt and polymorphic forms), 9,724,342 (formulations), 10,034,873 (methods of treatment), 10,039,757 (methods of treatment), 11,091,439 (crystalline salt forms), 11,091,440 (pharmaceutical composition), 11,098,015 (methods of treatment) and 11,298,349 (pharmaceutical composition), which are listed in the Approved Drug Products with Therapeutic Equivalence Evaluations, also referred to as the Orange Book, for CABOMETYX. On October 30,2024 we filed a complaint in the United States District Court for the District of Delaware (the Delaware District Court) for patent infringement against Sun asserting infringement of U.S. Patent Nos. 8,877,776, 11,091,439, 11,091,440, and 11,098,015. On January 22, 2025, Sun filed its response to the complaint, alleging that the asserted claims of U.S. Patent No. 8,877,776, 11,091,439, 11,091,440, and 11,098,015 are invalid and not infringed. Sun also filed counterclaims that, inter alia, seek a declaratory judgment that Sun’s ANDA would not infringe any valid and enforceable claim of U.S. Patent Nos. 8,877,776, 11,091,439, 11,091,440, 11,098,015, 9,724,342, 10,034,873, 10,039,757, and 11,298,349. We have not yet responded to Sun’s counterclaims. Other On November 18, 2024, Azurity Pharmaceuticals, Inc. (Azurity) filed a petition seeking inter partes (IPR) review of U.S. Patent No. 11,298,349 at the United States Patent and Trademark Office. The proceeding was accorded a filing date of December 12, 2024 and our preliminary response is due March 12, 2025. On January 9, 2025, Azurity filed a petition seeking IPR review of U.S. Patent No. 12,128,039 at the United States Patent and Trademark Office. The proceeding has not yet been accorded a filing date. The sale of any generic version of CABOMETYX earlier than its patent expiration could significantly decrease our revenues derived from the U.S. sales of CABOMETYX and thereby materially harm our business, financial condition and results of operations. It is not possible at this time to determine the likelihood of an unfavorable outcome or estimate of the amount or range of any potential loss. We may also from time to time become a party or subject to various other legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. Some of these proceedings have involved, and may involve in the future, claims that are subject to substantial uncertainties and unascertainable damages.
