Collaborative and Other Arrangements [Abstract] |
COLLABORATIONS AND OTHER ARRANGEMENTS | COLLABORATIONS AND OTHER ARRANGEMENTS We continue to pursue licensing and strategic collaborations and other similar arrangements with third parties for the development and commercialization of certain products and product candidates. These arrangements may involve two or more parties who are active participants in the operating activities of the collaboration and are exposed to significant risks and rewards depending on the commercial success of the activities. These arrangements may include non-refundable upfront payments, expense reimbursements or payments by us for options to acquire certain rights, contingent obligations by us for potential development and regulatory milestone payments and/or sales-based milestone payments, royalty payments, revenue or profit-sharing arrangements and cost-sharing arrangements. We also continue to pursue equity investments in third parties focused on the development and commercialization of products and product candidates. Merck Sharp & Dohme Corp. (“Merck”) On March 13, 2021, we entered into a license and collaboration agreement with Merck, a subsidiary of Merck & Co., Inc. to jointly develop and commercialize long-acting investigational treatments in HIV that combine Gilead’s investigational capsid inhibitor, lenacapavir, and Merck’s investigational nucleoside reverse transcriptase translocation inhibitor, islatravir. The collaboration will initially focus on long-acting oral and injectable formulations. Under the terms of the agreement, Gilead and Merck will share global development and commercialization costs at 60% and 40%, respectively, across the oral and injectable formulation programs. For long-acting oral products, Gilead will lead commercialization in the United States, and Merck will lead commercialization in the European Union (“EU”) and rest of the world. For long-acting injectable products, Merck will lead commercialization in the United States and Gilead will lead commercialization in the EU and rest of the world. Gilead and Merck will jointly promote the combination products in the United States and certain other major markets. We will share global product revenues with Merck equally until product revenues surpass certain pre-determined per formulation revenue tiers. Upon passing $2.0 billion in net product sales for the oral combination in a given calendar year, our share of revenue will increase to 65% for any revenues above the threshold for such calendar year. Upon passing $3.5 billion in net product sales for the injectable combination in a given calendar year, our share of revenue will increase to 65% for any revenues above the threshold for such calendar year. Reimbursements of research and development costs to or from Merck are recorded within Research and development expenses on our Condensed Consolidated Statements of Operations. Expenses recognized under the agreement were not material for the three and nine months ended September 30, 2021. No revenues have been recognized under the agreement for the three and nine months ended September 30, 2021. We will also have the option to license certain of Merck’s investigational oral integrase inhibitors to develop in combination with lenacapavir. Reciprocally, Merck will have the option to license certain of Gilead’s investigational oral integrase inhibitors to develop in combination with islatravir. Each company may exercise its option for such investigational oral integrase inhibitor of the other company within the first five years after execution of the agreement, following completion of the first Phase 1 clinical trial of that integrase inhibitor. Upon exercise of an option, the companies will split development costs and revenues, unless the non-exercising company decides to opt-out, in which case the non-exercising company will be paid a royalty. Arcus On May 27, 2020, we entered into a transaction with Arcus, which included entry into an option, license and collaboration agreement (the “Collaboration Agreement”) and a common stock purchase agreement and an investor rights agreement (together, and as subsequently amended the “Stock Purchase Agreements”). Under the Stock Purchase Agreements, we have the right to purchase additional shares of Arcus from Arcus over the five-year period beginning on the closing of the Stock Purchase Agreements, up to a maximum of 35% of the outstanding voting stock. We are subject to a three-year standstill, which period began on the date the parties entered into the Stock Purchase Agreements, restricting our ability to acquire voting stock of Arcus exceeding more than 35% of the then issued and outstanding voting stock of Arcus, subject to certain exceptions. Additionally, we agreed not to dispose of any equity securities of Arcus prior to the second anniversary of the closing of the Stock Purchase Agreements without the prior consent of Arcus, subject to certain exceptions. Pursuant to the Collaboration Agreement and Stock Purchase Agreements which closed on July 13, 2020, and a separate secondary equity offering which closed on May 29, 2020, we acquired approximately 8.2 million shares of Arcus common stock for approximately $261 million. In the first quarter of 2021, we amended and restated the common stock purchase agreement and acquired approximately 5.7 million additional shares of Arcus common stock for $220 million. As a result, we currently own a total of 13.8 million shares of Arcus, which represented approximately 19.5% of the issued and outstanding voting stock of Arcus immediately following the closing of the first quarter 2021 transaction. The amendment and restatement of the common stock purchase agreement in the first quarter of 2021 did not modify any of the terms above. We elected and applied the fair value option to account for our equity investment in Arcus whereby the investment is marked to market each reporting period based on the market price of Arcus shares. We believe the fair value option best reflects the underlying economics of the investment. Changes in fair value of the investment are recognized in Other income (expense), net on our Condensed Consolidated Statements of Operations. We initially recorded our equity investments in Arcus in Other long-term assets on our Condensed Consolidated Balance Sheets as the investments are subject to contractual lock-up provisions, subject to certain conditions. In the third quarter of 2021, we reclassified our equity investments in Arcus to Prepaid and other current assets on our Condensed Consolidated Balance Sheets as the contractual lock-up provisions will expire in July 2022. Other Arrangements During the three and nine months ended September 30, 2021 and 2020, we entered into several collaborations, equity investments and licensing arrangements as well as other similar arrangements that we do not consider to be individually material. We recorded upfront collaboration expenses related to these arrangements within Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations. Upfront collaboration expenses and cash payments made related to our equity investments were not material for the three and nine months ended September 30, 2021 and 2020. Under the financial terms of these arrangements, we may be required to make payments upon achievement of developmental, regulatory and commercial milestones, which could be significant. Future milestone payments, if any, will be reflected in our Condensed Consolidated Statements of Operations when the corresponding events become probable. In addition, we may be required to pay significant royalties on future sales if products related to these arrangements are commercialized. The payment of these amounts, however, is contingent upon the occurrence of various future events, which have a high degree of uncertainty of occurrence.
