Agreements | 10. Agreements Collaboration with Gilead On December 19, 2018 (the “Effective Date”), the Company entered into a three-year Master Collaboration Agreement (the “Gilead Collaboration Agreement”) with Gilead to discover and develop specific inhibitors of TGFβ activation focused on the treatment of fibrotic diseases. Under the collaboration, Gilead had exclusive options to license worldwide rights to product candidates that emerge from three of the Company’s TGFβ programs (each a “Gilead Program”). Pursuant to the Gilead Collaboration Agreement, the Company was responsible for antibody discovery and preclinical research through product candidate nomination, after which, upon exercising the option for a Gilead Program, Gilead would be responsible for the program’s preclinical and clinical development and commercialization. Such option could have been exercised by Gilead at any time from the Effective Date through a date that is 90 days following the expiration of the Research Collaboration Term for a given Gilead Program (no later than March 19, 2022), or until termination of the Gilead Program, whichever is earlier (the “Option Exercise Period”). On January 6, 2022, Gilead agreed to terminate its option exercise period for all programs. Revenue associated with the research and development and license performance obligations relating to the Gilead Programs was recognized as revenue as the research and development services were provided using an input method, according to the costs that were incurred on each Gilead Program and the costs that were expected to be incurred to satisfy the performance obligation. The transfer of control occurred over time. In management’s judgment, this input method was the best measure of progress towards satisfying the performance obligation. The amounts allocated to the three material rights provided by the options (“Material Rights”) was to be deferred on the Company’s consolidated balance sheet until either exercise or termination of the respective options. In January 2022, upon Gilead’s termination of its option exercise period for all programs, the Company recognized revenue of $33.2 million attributable to the Material Rights in the Company’s consolidated statements of operations and comprehensive loss, after which all revenue related to the Gilead Collaboration Agreement had been fully recognized. ​
