Collaboration Agreements [Abstract] |
Collaboration Agreements | 3. Collaboration Agreements In October 2018, the Company entered into a Research Collaboration and License Agreement (the 2018 Gilead Agreement) with Gilead Sciences, Inc. (Gilead). Pursuant to the terms of the 2018 Gilead Agreement, the Company received an initial upfront payment of $50.0 million. Gilead had the option to obtain exclusive, worldwide licenses to develop and commercialize up to five validated programs (Gilead Program License). In August 2020, the Company and Gilead entered into an Amended Research Collaboration and License Agreement (the Gilead Agreement), which superseded and replaced the 2018 Gilead Agreement. The Gilead Agreement represents a continuation of the initial target discovery and validation research and development efforts begun under the 2018 Gilead Agreement. Under the Gilead Agreement: • The Company received upfront, non-refundable consideration of $125.0 million from Gilead upon execution of the Gilead Agreement in 2020; • The term of the 2018 Gilead Agreement ended on the date the Gilead Agreement was executed. The Gilead Agreement has a research term of seven years; • Gilead expanded its option to license up to 15 programs for which Gilead may obtain exclusive, worldwide licenses to develop and commercialize therapies, subject to applicable license fees; • Prior to exercising its option to license a program, Gilead may “extend” such program, in which case Gilead will pay research option-extension fees and the Company will continue to collaborate with Gilead to discover and develop programs, potentially through early clinical development; • Gilead has the option to “reserve” a target during which Gilead may: (i) license the target, (ii) “extend” the target, or (iii) decline the target, during the designated reserve target period. If, during the reserve target period Tango elects to work on the reserved target, Tango will retain full rights to the target program and Gilead receives a right of first negotiation in connection with any future partnering or licensing of such target by Tango, if any; and • For up to five programs licensed by Gilead, the Company has the option to co-develop and co-promote the lead product in the U.S., subject to certain exceptions, and is eligible to receive tiered royalties in the first decile on ex-U.S. sales. The Company is eligible to receive up to $410.0 million per program in license, research option-extension, and clinical, regulatory, and commercial milesto nes and royalties on future sales of commercialized products, if any. In August 2020, Gilead also made an equity investment of $20.0 million into the Company as a participant in the Company’s Series B-1 preferred stock offering. At the time of the original investment, including as of the March 31, 2024 balance sheet date, Gilead maintains an ownership of less than 10% of the Company's common stock and is thus not considered to be a related party to the Company. Accounting for the Gilead Collaboration The Gilead Agreement is accounted for under ASC 606. The Company identified a single combined performance obligation under the Gilead Agreement consisting of the research services and continued participation on the joint steering committee during the research term. For research option-extension fees, the Company determined that the additional goods and services relating to the continued research services were not distinct from the early-stage research services already promised to Gilead under the on-going research plan. Consideration pertaining to each of the research option-extensions is paid to the Company in equal quarterly installment payments over an agreed upon payment schedule. The research option-extension consideration are added to the transaction price under the Gilead Agreement. License fees are recognized as revenue immediately as the Company has no continued involvement in the advancement of the program, Gilead can benefit from the license on its own, and the license is separately identifiable from the research services. Gilead Revenue Recognized The total transaction price allocated to the combined performance obligation under the Gilead Agreement was $199.0 million at March 31, 2024. The total transaction price was comprised of the $50.0 million upfront payment pursuant to the 2018 Gilead Agreement, the $125.0 million upfront payment pursuant to the Gilead Agre ement, and $24.0 million in payment pursuant to research option-extension fees in December 2020 and in September 2021. During the three months ended March 31, 2024 and 2023, the Company recognized $6.5 million and $5.8 million, respectively, of collaboration revenue associated with the Gilead agreements based on performance completed during each period. The Company reevaluates the transaction price and the total estimated costs expected to be incurred to satisfy the performance obligations at the end of each reporting period and as uncertain events, such as changes to the expected timing and cost of certain research and development activities that the Company is responsible for, are resolved or other changes in circumstances occur. As of March 31, 2024 and December 31, 2023, the Company had short-term deferred revenue of $23.1 million and $25.7 million, respectively, and long-term deferred revenue of $62.8 million and $66.7 million, respectively, related to the Gilead collaboration. The remaining long-term deferred revenue is expected to be recognized proportionally to the completed obligations over an expected remaining contractual term of approximately 3.4 years. Amounts due to the Company that have not yet been received are recorded as accounts receivable and amounts received that have not yet been recognized as revenue are recorded as deferred revenue on the Company’s condensed consolidated balance sheets. Costs incurred pursuant to the Gilead Agreements are recorded as research and development expense.
