License And Other Related Agreements [Abstract]
Material Agreements	Material Agreements License Agreement with QED Therapeutics, Inc. In October 2019, the Company entered into a license agreement (the “QED License Agreement”) with QED Therapeutics, Inc. (“QED”), as subsequently amended, under which the Company obtained an exclusive license under certain patents and know-how (including patents and know-how that QED licensed from QED’s upstream licensor) to develop, manufacture, use, sell, import, and commercialize QED’s ATP-competitive, FGFR1-3 tyrosine kinase inhibitor, infigratinib, in pharmaceutical products in the licensed territory of Mainland China, Macau, Hong Kong, Taiwan, Thailand, Singapore and South Korea, in the licensed field of human prophylactic and therapeutic uses in cancer indications. In September 2020, the Company entered into an amendment with QED to reduce the licensed territories to include Mainland China, Macau and Hong Kong. In December 2021, the Company entered into a second amendment with QED to modify the Company’s development obligations with respect to certain clinical trials, and change the development milestone payments the Company owes to QED and the royalty rates for the tiered royalties on net sales of licensed products the Company will pay to QED. Under the QED License Agreement, QED received a nonrefundable upfront payment of $10.0 million and was granted warrants to purchase 100,000 ordinary shares in Lian Oncology, a subsidiary of LianBio, valued at $1.0 million. Pursuant to ASC 505-50, as the fair value of the warrants were more reliably determinable than the fair value of the benefits received from the licensing agreement, the Company valued the warrants using the Black-Scholes Model. The warrants were issued in three tranches with the aggregate number of shares across all tranches equaling 10% of the fully diluted equity of Lian Oncology as of the issue date. Vesting of the warrant shares are linked to regulatory milestones and the warrants expire 10 years from the issue date. The amended and restated option agreement also provided QED with the option to choose to either convert the warrant (“Subsidiary Warrant”) into ordinary shares of the Company (“Parent Company Shares”) or a warrant to purchase a certain number of Parent Company Shares (“Parent Company Warrant”) immediately prior to an IPO of the Company. In the event QED chose to convert the Subsidiary Warrant into Parent Company Shares, the number of Parent Company Shares QED was entitled to receive would have been calculated as the aggregate fair market value of the ordinary shares of Lian Oncology that are under the Subsidiary Warrant, divided by the per share fair market value of the Parent Company Shares, on a fully diluted and as-converted basis and as of the date the Company sent QED the notice of the IPO. In the event QED chose to convert the Subsidiary Warrant into the Parent Company Warrant, the number of Parent Company Shares under the Parent Company Warrant QED was entitled to receive would have been calculated as the aggregate intrinsic value of the Subsidiary Warrant (the number of the ordinary shares of Lian Oncology under the Subsidiary Warrant multiplied by the difference between the strike price of the Subsidiary Warrant and the per share fair market value of Lian Oncology), divided by the per share intrinsic value of the Parent Company Warrant (the difference between the strike price of the Parent Company Warrant and the per share fair market value of Parent Company Shares), on a fully diluted and as-converted basis on the date of the warrant conversion. This conversion feature was not required to be bifurcated as it is clearly and closely related to the equity host instrument, pursuant to ASC 815. On October 18, 2021, based on the conversion feature, LianBio issued to QED a warrant to purchase 347,569 of its ordinary shares at an exercise price of $0.000017100448 per share and, concurrently with such issuance, the Subsidiary Warrant was deemed to be performed and settled in full and was irrevocably terminated. Additionally, QED is entitled to receive from the Company development milestone payments of up to $7.0 million upon achievement of specified development milestones, and sales milestone payments of up to $87.5 million based on cumulative net sales of infigratinib, in addition to tiered royalties on net sales of licensed products at the greater of (a) percentage rates in the mid- to high-teens on the net sales of the licensed products, or (b) the applicable rate payable under QED’s agreement with its upstream licensor (capped in the mid-teens). No payments were made under this agreement during the three and nine months ended September 30, 2023. In August 2023, LianBio received a $1.5 million payment under the terms of the QED License Agreement for the reimbursement of research and development costs. License Agreement with MyoKardia In August 2020, the Company entered into an exclusive license agreement (the “MyoKardia License Agreement”) with MyoKardia Inc. (“MyoKardia,” now a wholly-owned subsidiary of Bristol-Myers Squibb (“BMS”)), under which the Company obtained an exclusive license under certain patents and know-how of MyoKardia to develop, manufacture, use, sell, import and commercialize MyoKardia’s proprietary compound, mavacamten, in the licensed territory of Mainland China, Hong Kong, Macau, Taiwan, Thailand and Singapore, and in the licensed field of any indication in humans, which includes any prophylactic or therapeutic use in humans. Under the MyoKardia License Agreement, MyoKardia received a nonrefundable upfront payment of $40.0 million and was granted a warrant to purchase 170,000 ordinary shares in Lian Cardiovascular, a subsidiary of LianBio, valued at $33.8 million. Pursuant to ASC 505-50, as the fair value of the warrants were more reliably determinable than the fair value of the benefits received from the licensing agreement, the Company valued the warrants using the Black-Scholes Model and the underlying assumptions are discussed in further detail in Note 10 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. The warrants, representing 17% of the fully diluted equity of Lian Cardiovascular, are exercisable by MyoKardia at any time after issuance. The amended and restated option agreement also provided MyoKardia with the option to choose to either convert the warrant (“Subsidiary Warrant”) into ordinary shares of the Company (“Parent Company Shares”) or a warrant to purchase a certain number of Parent Company Shares (“Parent Company Warrant”) immediately prior to an IPO of the Company. MyoKardia was entitled to choose to convert the Subsidiary Warrant into Parent Company Shares, and the number of Parent Company Shares MyoKardia was entitled to receive would have been calculated as the aggregate fair market value of the ordinary shares of Lian Cardiovascular that are under the Subsidiary Warrant, divided by the per share fair market value of the Parent Company Shares, on a fully diluted and as-converted basis on the date the Company sent MyoKardia the notice of the IPO. Alternatively, MyoKardia was entitled to choose to convert the Subsidiary Warrant into the Parent Company Warrant, and the number of Parent Company Shares under the Parent Company Warrant that MyoKardia was entitled to receive would be calculated as the aggregate intrinsic value of the Subsidiary Warrant (the number of the ordinary shares of Lian Cardiovascular under the Subsidiary Warrant multiplied by the difference between the strike price of the Subsidiary Warrant and the per share fair market value of Lian Cardiovascular), divided by the per share intrinsic value of the Parent Company Warrant (the difference between the strike price of the Parent Company Warrant and the per share fair market value of Parent Company Shares), on a fully diluted and as-converted basis on the date of the warrant conversion. This conversion feature was not required to be bifurcated as it was clearly and closely related to the equity host instrument, pursuant to ASC 815. As of October 12, 2021, MyoKardia elected not to exercise this option and, therefore, continued to hold its warrant to purchase 170,000 ordinary shares in Lian Cardiovascular. MyoKardia’s option to convert the warrant irrevocably terminated upon the completion of the Company’s IPO. Additionally, MyoKardia was entitled to receive a nonrefundable financing milestone payment of $35.0 million upon a specified financing event, which occurred on October 29, 2020. The financing milestone was recorded at present value upon execution of the MyoKardia License Agreement, with total imputed interest of $2.3 million accreted under the effective interest method through the date the liability was settled. The financing milestone was paid to MyoKardia in December 2020 as a result of the Series A Preferred financing. Additionally, MyoKardia is entitled to receive from the Company development milestone payments of up to $60.0 million upon achievement of specified development milestones, and sales milestone payments of up to $87.5 million based on cumulative net sales of mavacamten, plus tiered double-digit royalties on net sales. The Company paid the first development milestone of $5.0 million during the twelve months ended December 31, 2022. No payments were made under this agreement during the three and nine months ended September 30, 2023. On August 11, 2023, the Company and its wholly-owned subsidiary LianBio Licensing, LLC, Lian Cardiovascular Limited, and Shanghai LianBio Development Co., Ltd. (each, a “Lian Party”, and collectively, “Lian Parties”) entered into a supplemental agreement (the “nHCM Supplemental Agreement”) with MyoKardia in relation to a clinical trial for mavacamten to be conducted in Mainland China for treatment of non-obstructive hypertrophic cardiomyopathy (“nHCM”). Pursuant to the nHCM Supplemental Agreement, MyoKardia will be the sponsor of a global trial with respect to mavacamten for nHCM (the “Global Clinical Study”), and will authorize and permit Shanghai LianBio Development Co., Ltd. to conduct a portion of the Global Clinical Study in Mainland China (the “China Study”) in accordance with a development plan for the China Study. Lian Parties are obligated to use commercially reasonable efforts to achieve certain key milestones including enrolling in Mainland China a certain percentage of the total number of patients planned to be enrolled in the Global Clinical Study, and dosing of the first patient in the China Study within a certain period of time after the first submission of the applicable Clinical Trial Application to the applicable regulatory authority. During the term of the nHCM Supplemental Agreement, any Lian Party may effect, authorize or enter into any agreement to effect, a change of control so long as (i) the acquirer is a permissible third party acquiror that satisfies certain specified standards in the nHCM Supplemental Agreement, (ii) the acquiror agrees in writing to be bound by the nHCM Supplemental Agreement and the MyoKardia License Agreement, and (iii) in the event an acquirer engaged in any competing program, it will implement reasonable firewall safeguards.. On October 24, 2023 (the “Termination Effective Date”), the Company entered into a Termination Agreement, (the “Termination Agreement”), by and among MyoKardia and BMS (the “Licensor Parties”) and, as applicable, E.R. Squibb Co. & Sons, L.L.C. and Swords Laboratories Unlimited Company, on the one hand, and the Company, Lian Cardiovascular, Lian Cardiovascular Limited, LianBio Development (HK) Limited, LianBio Licensing, LLC and Shanghai LianBio Development Co., Ltd. (collectively, the “Licensee Parties”), on the other hand. Pursuant to the Termination Agreement, the Company terminated the MyoKardia License Agreement. The Company received a one-time payment of $350 million as consideration for terminating the MyoKardia License Agreement and certain ancillary agreements, including the nHCM Supplemental Agreement and the Warrant, and was released from expected payment obligations of $127.5 million in remaining milestone payments under the MyoKardia License Agreement. Pursuant to the Termination Agreement, the Licensee Parties will perform certain transition activities to facilitate the transition of development and commercialization of mavacamten in the applicable territories to the Licensor Parties, including assignment, transfer and transition of certain related rights, agreements, documents, filings and studies as well as certain ongoing regulatory activities and support related to mavacamten during the transition period, as applicable. The transition activities are expected to be completed within 18 months following the Termination Effective Date. In addition, the Licensor Parties will reimburse the Licensee Parties for certain costs and expenses incurred in the performance of transition activities, for certain personnel costs and for amounts that become due under certain agreements following the Termination Effective Date. The Termination Agreement further provides that certain employees of the Licensee Parties or their affiliates who are working on the development and commercialization of mavacamten will receive offers of employment from entities designated by the Licensor Parties. License Agreement with Navire In August 2020, pursuant to the BridgeBio exclusivity agreement, the Company entered into an exclusive license agreement with Navire Pharma, Inc. (“Navire”), a BridgeBio affiliate. Pursuant to the license agreement, Navire granted to the Company an exclusive, sublicensable license under certain patents and know-how of Navire to develop, manufacture, use, sell, import and commercialize Navire’s proprietary SHP2 inhibitor, BBP-398 (formerly known as IACS-15509) in the licensed territory of Mainland China, Hong Kong, Macau, Taiwan, Thailand, Singapore, and South Korea.

The Company paid the first development milestone of $8.5 million for IND acceptance in the PRC in 2021. No payments were made under this agreement during the three and nine months ended September 30, 2023. Pfizer Strategic Collaboration In November 2020, the Company entered into a strategic collaboration agreement (the “Pfizer Collaboration Agreement”) with Pfizer Inc. (“Pfizer”), pursuant to which Pfizer will contribute up to $70.0 million of restricted, non-dilutive capital (the “Funds”), including a $20.0 million upfront payment, toward the Company’s in-licensing and co-development activities in Greater China. The Company has accounted for the Pfizer Collaboration Agreement as a contract to perform research and development services for others under ASC 730-20 and the consideration received for performing these services will be recognized as contra-R&D in the Consolidated Statement of Operations and Comprehensive Loss as the services are performed. Upon receipt in 2021, the upfront payment was recorded as restricted cash within the consolidated balance sheet and will remain restricted until such time as the upfront payment is utilized for specified in-licensing and co-development activities or until the Pfizer Collaboration Agreement terminates. Under the Pfizer Collaboration Agreement, Pfizer and LianBio will form a joint collaboration committee to discuss potential third party in-license opportunities and development and commercialization of the Company’s products in Greater China. In the event the Company seeks to engage a third-party commercialization partner with respect to the commercialization of the Company’s future products in Greater China, Pfizer will have a right to opt into such product. Upon opting in, a portion of the Funds will be used to pay for development and commercialization costs of such product and Pfizer will thereafter have a right of first negotiation and right of last refusal to obtain the commercialization rights of such product in Greater China, in each instance for additional, separate financial consideration. During the collaboration, Pfizer may provide in-kind support to the Company for marketing, development and regulatory activities. In December 2022, the Company, Pfizer, and ReViral Ltd. (“ReViral,” now a wholly owned subsidiary of Pfizer) entered into a commercial agreement (the “Pfizer Commercial Agreement”) with respect to sisunatovir (a fusion inhibitor product for the treatment of respiratory syncytial virus (“RSV”)) as the first opted-in product under the Pfizer Collaboration Agreement. Pursuant to the Pfizer Commercial Agreement, LianBio will assign and transfer its development and commercialization rights to sisunatovir in Mainland China, Hong Kong, Macau and Singapore (the “Territory”) to Pfizer. Under the Pfizer Commercial Agreement, the $20.0 million upfront payment, which was previously received and recorded as restricted cash, paid by Pfizer to LianBio in 2020 pursuant to the Pfizer Collaboration Agreement was released, as there are no further obligations and the associated contingencies were resolved. In addition, LianBio could also receive up to $135.0 million in potential development and sales milestones contingent on sisunatovir achieving a specified regulatory milestone event prior to the end of October 2035 and specified net sales milestone events. LianBio is further entitled to receive tiered payments in the low single digits on a percentage of net sales of sisunatovir in the Territory. Pfizer will lead all development and commercial activities, use commercially reasonable efforts to develop and seek regulatory approval for sisunatovir as a fusion inhibitor product for treatment of RSV as a single active pharmaceutical product in Mainland China, assume all costs in the Territory, and will waive LianBio’s milestone payment and royalty payment obligations previously due to ReViral pursuant to the Co-Development and License Agreement dated March 1, 2021, by and between LianBio Respiratory Limited and ReViral, which was superseded in its entirety by the Pfizer Commercial Agreement. The Company has accounted for the Pfizer Commercial Agreement under ASC 450-30 and the consideration received under the agreement will be recognized as other income as they become realizable.

Under the license agreement, Tarsus received a nonrefundable upfront payment of $15.0 million and was granted three warrants to purchase 125,000 ordinary shares in Lian Ophthalmology, a subsidiary of LianBio, valued at $9.4 million (the “Tarsus Warrants”). Pursuant to ASC 505-50, as the fair value of the warrants were more reliably determinable than the fair value of the benefits received from the licensing agreement, the Company valued the warrants using the Black-Scholes Model and the underlying assumptions are discussed in further detail in Note 10 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The warrants were issued in three tranches with the aggregate number of shares across all tranches equaling 12.5% of the fully diluted equity of Lian Ophthalmology as of the issue date. Vesting of the warrant shares are linked to regulatory milestones and the warrants expire 10 years from the issue date. Pursuant to a related option agreement (the “Tarsus Option Agreement”), Tarsus also had the option to convert the warrants into ordinary shares of the Company (“Parent Company Shares”) or warrants to purchase a certain number of the Company’s ordinary shares (“Parent Company Warrants”) based on appreciation of the value in the Lian Ophthalmology since the inception of the Tarsus License Agreement. This conversion feature was not required to be bifurcated as it was clearly and closely related to the equity host instrument, pursuant to ASC 815. On October 18, 2021, Tarsus exercised its options to convert the Tarsus Warrants under the Tarsus Option Agreement and the Company subsequently issued to Tarsus 78,373 of its ordinary shares and two warrants to purchase an aggregate of 156,746 of its ordinary shares at an exercise price of $0.000017100448 per share.
