Revenue Recognition and Deferred Revenue [Abstract] |
Regeneron License and Collaboration Arrangement | 7. Regeneron License and Collaboration Arrangement Agreement Terms On July 29, 2016, the Company entered into a license and collaboration agreement with Regeneron, which was amended in April 2019, with such amendment becoming effective in connection with Regeneron’s investment in the Company’s Series B redeemable convertible preferred stock private placement transaction in July 2019 (as amended, the Regeneron Agreement). Financial Terms. The Company received a non-refundable upfront payment of $25.0 million from Regeneron upon execution of the Regeneron Agreement and an aggregate of $20.0 million of additional payments for research funding from Regeneron as of June 30, 2022. In addition, Regeneron may have to pay the Company additional amounts in the future consisting of up to an aggregate of $80.0 million of option exercise fees, as specified in the Regeneron Agreement. Regeneron must also pay the Company high single digit royalties as a percentage of net sales for ICPs to targets for which it has exclusive rights, and low single digit royalties as a percentage of net sales on any non-ICP product comprising a targeting moiety generated by the Company through the use of Regeneron’s proprietary mice. The Company must pay Regeneron mid-single to low double digit, but less than teens, of royalties as a percentage of net sales of ICPs to targets for which the Company has exercised exclusive rights, and low to mid-single digit of royalties as a percentage of net sales of targeting moieties generated from the Company’s license to use Regeneron’s proprietary mice. Royalties are payable until the longer of the expiration or invalidity of the licensed patent rights or twelve (12) years from first commercial sale. Equity Investments. In connection with its collaboration, Regeneron and the Company entered into a side letter pursuant to which, among other matters, Regeneron was granted certain stockholder rights and investment rights in connection with the Company’s next equity financing that met certain criteria and in connection with an initial public offering by the Company. Regeneron exercised its investment right and purchased approximately $10.0 million of the Company’s Series B redeemable convertible preferred stock in a private placement transaction in July 2019. The remaining obligations under the side letter agreement terminated immediately prior to the closing of the merger with resTORbio. Revenue Recognition The Company identified the following material promises under the Regeneron Agreement: (1) a research license, (2) a collaboration invention license, (3) a trademark license, (4) research and development services during the research term, (5) manufacturing services to manufacture collaboration ICPs for the research programs, (6) participation in the joint research committee, and (7) information sharing during the research term. The Company considered that the licenses granted under the Regeneron Agreement are not capable of being distinct and are not distinct from the research and development and manufacturing services within the context of the Regeneron Agreement, because 1) such licenses are for the research and development effort during the research term, unless Regeneron exercises its option under the Regeneron Agreement, 2) the research and development services significantly increase the utility of such licenses, and 3) research and development services require collaboration ICPs being manufactured. At contract inception, the Company determined the transaction price of the Regeneron Agreement to be $55.0 million, consisting of the $25.0 million upfront payment and the aggregate research funding fees of $30.0 million payable over the research term. In order to determine the transaction price, the Company evaluated all the payments to be received during the duration of the contract. Per the terms of the original Regeneron Agreement prior to the amendment effective from July 2019, the research funding fees of $30.0 million were payable merely due to the passage of time and therefore did not represent a variable consideration. After the amendment became effective in July 2019, $20.0 million of these fees became contingent upon meeting certain development and regulatory milestones. Therefore, the Company concluded that after the amendment such potential payments became variable consideration. The receipt of the variable consideration was subject to substantial uncertainty and was therefore excluded from the transaction price upon the effective date of the amendment. Accordingly, the transaction price was reduced to $35.0 million in July 2019. The Company re-evaluates the transaction price if there is a significant change in facts and circumstances at least at the end of each reporting period. The Company increased the transaction price by $10.0 million in June 2020 to $45.0 million when it achieved the milestone for the selection of a clinical candidate to the second collaboration target under the Regeneron Agreement. The Company recorded a $4.0 million revenue reduction in the first quarter of 2021 as a result of an adjustment to cumulative revenue recognized due to a change in overall estimated costs primarily due to an extension of time to fulfill the combined performance obligation. During the six months ended June 30, 2022, the Company recognized $5.0 million in revenue related to the performance obligations described above. The Company also recognized $20.0 million of revenue related to Regeneron's exercise of an option for ADI-002, which is described below, and resulted in an aggregate of $25.0 million recorded as revenue during the six months ended June 30, 2022. The Company's obligations under the combined performance obligation were completed during the first quarter of 2022. The Company also evaluated whether the option provided to Regeneron represents a material right that would require separate deferral and recognition. The option exercise will provide Regeneron with a development and commercial license to develop and commercialize the optioned collaboration ICPs. The Company concluded that the $25.0 million upfront payment to the Company was not negotiated to provide incremental discount for the future option fees payable upon Regeneron’s exercise of the option. The option provides Regeneron with a license for intellectual property that will be improved from the inception of the Regeneron Agreement. In addition, the option fee is significant compared to the sum total of the upfront payment and research funding fees in the original Regeneron Agreement. Therefore, the Company determined that the option provided to Regeneron does not represent a material right and that any potential exercise of the option should be accounted as a separate contract. Hence, upon the option exercise by Regeneron the option fee would be allocated to the development and commercial license which would be the only performance obligation in that separate contract and recognized as revenue when control of the license rights is transferred to Regeneron. On January 28, 2022, Regeneron exercised its option to license the exclusive, worldwide rights to ADI-002, an allogeneic gamma delta chimeric antigen receptor (CAR) T cell therapy directed against Glypican-3, pursuant to the Regeneron Agreement. In conjunction with the exercise of the Option, Regeneron paid an exercise fee of $20.0 million to the Company on January 28, 2022, and the Company completed the transfer of the associated license rights to Regeneron during the first quarter of 2022. Pursuant to the Regeneron Agreement, upon Regeneron’s exercise of the option, the Company had a specified period of time to elect to co-fund future development costs of ADI-002, and to participate in any potential profits with Regeneron up to a specified co-funding percentage in various geographic regions, including on a worldwide basis (Co-Funding Option). The Company elected not to exercise its Co-Funding Option for ADI-002. Accordingly, Regeneron is responsible, at its sole cost, for all development, manufacturing and commercialization of ADI-002 and must pay the Company high single digit royalties as a percentage of any net sales of ADI-002 for a period commencing on the first commercial sale until the longer of (i) the expiration or invalidity of the licensed patent rights or (ii) a low double digit amount of years from first commercial sale. The following tables present changes in the Company’s contract liabilities for the six months ended June 30, 2022 and 2021 (in thousands):
Six Months Ended June 30, 2022 |  | Balance at Beginning of Period |  |  | Deductions (1) |  |  | Balance at End of Period |

(1) Deductions to contract liabilities relate to deferred revenue recognized as revenue during the reporting period. Deductions are shown net of additions that are the result of a reduction to cumulative revenue recognized as a result of a change in overall estimated costs, primarily due to an extension of time to fulfill the combined performance obligation, which was recorded as a change in estimate during the six months ended June 30, 2021. As of June 30, 2022, there were no contract liabilities related to the Regeneron Agreement. Additionally, as of June 30, 2022, there were no contract assets which would be reflected as accounts receivable-related party on the consolidated balance sheet. As of June 30, 2021, contract liabilities related to the Regeneron Agreement of $13.1 million was comprised of the $25.0 million upfront payment and additional $5.0 million research funding fees in each of 2017 and 2018, and $10.0 million for achievement of the milestone for the selection of a clinical candidate to the second collaboration target in June 2020, less $27.8 million of cumulative license and collaboration revenue recognized from the inception of the Regeneron Agreement as of June 30, 2021.
