Collaboration Agreements [Abstract] |
Collaboration Agreements | 3. Collaboration Agreements 2018 Gilead Agreement 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 2018 Gilead Agreement, the Company performed target discovery and validation activities in accordance with an agreed-upon multi-year research plan. During the initial three-year research term, Gilead had the option to obtain exclusive, worldwide licenses to develop and commercialize up to five validated programs (Gilead Program License). Gilead paid the Company a $50.0 million non-refundable upfront payment upon the execution of the 2018 Gilead Agreement and is eligible to receive certain milestone payments. The Company assessed this arrangement in accordance with ASC 606, Revenue from Contracts with Customers, and concluded that the contract counterparty, Gilead, was a customer. The Company identified a single performance obligation under the arrangement consisting of the combination of participating on the joint steering committee and the research and development services provided during the research term. The identified promises were determined to not be individually distinct due to the specialized nature of the early-stage research services to be provided by the Company and the interdependent relationship between the promises. The Company determined that the option for Gilead to extend the term of the arrangement was not priced at a discount, and therefore did not provide Gilead with a material right. This option will be excluded from the transaction price until exercised. At the inception of the 2018 Gilead Agreement, the Company also determined that the Gilead program license options provided to Gilead did not include a material right. The total transaction price, subject to variable consideration constraints, was allocated to the combined single performance obligation. The Company determined that the single combined performance obligation is satisfied over time as the customer is simultaneously receiving and consuming the benefit of the Company’s performance. The future milestone payments represent variable consideration that is fully constrained at inception of the arrangement as the achievement of the milestone events are highly uncertain. Amended Gilead Agreement In August 2020, Gilead 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, as well as of the March 31, 2023 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. In August 2020, the Company and Gilead also 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 milestones and royalties on future sales of commercialized products, if any. The Gilead Agreement was accounted for as a modification of the 2018 Gilead Agreement under ASC 606 as both the scope and price of the contract were changed under the Gilead Agreement. The additional goods and services to be provided under the Gilead Agreement are not distinct from the combined performance obligation identified under the 2018 Gilead Agreement which was only partially satisfied at the date of contract modification. As such, 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. As a result, the Company’s progress towards completing its research services to Gilead over the seven-year term of the Gilead Agreement was lower than its progress under the three-year term of the 2018 Gilead Agreement and a cumulative catch-up adjustment was recorded during the third quarter of 2020 resulting in a charge of $11.3 million against revenue previously recognized through the date of the Gilead Agreement. In December 2020 and in September 2021, Gilead elected to extend two programs for a research extension fee of $12.0 million each. 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 was added to the transaction price under the Gilead Agreement. Gilead Revenue Recognized The total transaction price allocated to the combined performance obligation under the Gilead Agreement was $199.0 million at March 31, 2023. 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 Agreement, and $24.0 million pursuant to the research option-extension fee payments related to decisions made in 2020 and 2021. During the three months ended March 31, 2023 and 2022, the Company recognized $5.8 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, 2023 and December 31, 2022, the Company had short-term deferred revenue of $34.0 million and $31.8 million, respectively, and long-term deferred revenue of $84.1 million and $92.1 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 4.4 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 unaudited condensed consolidated balance sheets. Costs incurred pursuant to the Gilead Agreements are recorded as research and development expense.
