License And Collaboration Agreement [Abstract]
License and Collaboration Agreements	10. License and Collaboration Agreements License Development and Commercialization Agreement with BMS On May 12, 2022, BridgeBio and our subsidiary, Navire, entered into an exclusive license development and commercialization agreement with BMS (the “Navire-BMS License Agreement”), pursuant to which Navire granted BMS exclusive rights to develop and commercialize Navire’s product candidate, BBP-398, in all indications worldwide, except for the People’s Republic of China, Macau, Hong Kong, Taiwan, Thailand, Singapore, and South Korea (the “Asia Region”). The development and commercialization of BBP-398 within the Asia Region is governed under the Navire-LianBio License Agreement (as discussed below). The Navire-BMS License Agreement expands an earlier agreement between Navire and BMS that was executed in July 2021 to study BBP-398 in a combination therapy trial to treat advanced solid tumors with KRAS mutations (the “2021 Navire-BMS Agreement”). The Navire-BMS License Agreement does not alter the terms of the 2021 Navire-BMS Agreement. Under the terms of the Navire-BMS License Agreement, Navire was entitled to receive a non-refundable, upfront payment of $90.0 million, which Navire received in full in June 2022. Additionally, Navire is eligible to receive additional payments totaling up to approximately $815.0 million in the aggregate, subject to the achievement of development, regulatory and commercial milestones, as well as tiered royalties in the low-to-mid teens as a percentage of adjusted net sales by BMS of the licensed products sold worldwide, outside of the Asia Region. Navire will retain the option to acquire higher royalties in the United States in connection with funding a portion of development costs upon the initiation of registrational studies. Based on the terms of the Navire-BMS License Agreement, Navire will continue to lead its ongoing Phase 1 monotherapy and combination therapy trials (collectively, the “Phase 1 Trials”), and BMS will lead and fund all other development and commercialization activities. Navire is fully funding the Phase 1 trials with the exception of the combination therapy governed under the 2021 Navire-BMS Agreement. In accordance with the 2021 Navire-BMS Agreement, both parties are sharing all research and development costs equally for this trial. We have recorded all research and development costs for the Phase 1 Trials, as well as the reimbursement for the costs associated with the trial governed by the 2021 Navire-BMS Agreement within research and development in our condensed consolidated statement of operations. We determined that the Navire-BMS License Agreement falls within the scope of ASC 606 as BMS is a customer in this arrangement, and we identified the following performance obligations in the agreement: • an exclusive license to develop and commercialize BBP-398 and the related know-how; and • research and development services to complete the Phase 1 Trials for BBP-398 (expected to be completed in 2025). We determined that the performance obligations outlined above are capable of being distinct and distinct with the context of the contract given such rights and activities are independent of each other. The license can be used by BMS without the research and development services. Similarly, those services provide a distinct benefit to BMS within the context of the contract, separate from the license, as the services could be provided by BMS or another third party without our assistance. We may enter into clinical and commercial supply agreements for the licensed territory. We determined that the optional right to future products under these supply agreements does not represent a material right. In March 2023, Navire and BMS entered into a clinical supply agreement for the supply of clinical quantities of the licensed product. No clinical supplies were provided to BMS during the three months ended March 31, 2023. We determined the initial transaction price at inception of the Navire-BMS License Agreement to be $90.0 million, which is comprised of the fixed and non-refundable upfront payment. No additional development, regulatory, or sales milestone payments are included in the transaction price, as all such payments are variable consideration that are fully constrained as of March 31, 2023. We include variable consideration in our transaction price to the extent that it is probable that it will not result in a significant revenue reversal when the uncertainty associated with the variable consideration is subsequently resolved. As part of management’s evaluation of the variable consideration, we considered numerous factors, including the fact that achievement of the milestones is outside of our control, contingent upon the success of our existing and future clinical trials, BMS’ efforts, and receipt of regulatory approval that is subject to scientific risks of success. Royalty arrangements and commercial-based milestones will be recognized when the sales occur or the milestones are achieved pursuant to the sales-based royalty exception under ASC 606 because the license is the predominant item to which the royalties or commercial-based milestones relate. We will re-evaluate the transaction price at each reporting period and as uncertain events are resolved or other changes in circumstances occur. We allocated the transaction price of $90.0 million based on the stand-alone selling prices (“SSP”) of each of the performance obligations as follows: • $70.2 million for the upfront transfer of the license; and • $19.8 million for ongoing research and development services. The SSP for the license was determined using an approach that considered discounted, probability-weighted cash flows related to the license transferred. The SSP for the ongoing research and development services were based on estimates of the associated effort and cost of these services, adjusted for a reasonable gross profit margin that would be expected to be realized under similar contracts. We recognized revenue for each of the two performance obligations as follows: • We recognized revenue related to the license at a point in time upon transfer of the rights and control of the license to BMS. The transfer of the rights and control of the license occurred in June 2022, thus we recognized the full amount allocated to the license and related know-how during the three months ended June 30, 2022. • The research and development services performance obligation consists of our completion of the Phase 1 Trials. We are recognizing revenue related to the research and development services over time using an input method to measure progress by utilizing costs incurred to-date relative to total expected costs. We expect to complete the Phase 1 Trials in 2025. Revenue recognized related to this performance obligation for the three months ended March 31, 2023 was $1.7 million. Our condensed consolidated balance sheet as of March 31, 2023 includes a deferred revenue balance of $13.6 million ($6.7 million presented as “Deferred revenue, current portion” and $6.9 million included in “Other long-term liabilities”) related to our research and development services obligation. Our condensed consolidated balance sheet as of December 31, 2022 includes a deferred revenue balance of $15.3 million ($8.2 million presented as “Deferred revenue, current portion” and $7.1 million included in “Other long-term liabilities”) related to our research and development services obligation. License and Collaboration Agreement with Helsinn On March 29, 2021, QED entered into a license and collaboration agreement with Helsinn Healthcare S.A. (“HHC”) and Helsinn Therapeutics (U.S.), Inc. (“HTU”, and collectively with HHC, “Helsinn”) (the “QED-Helsinn License and Collaboration Agreement”), pursuant to which QED granted to HHC exclusive licenses to develop, manufacture and commercialize QED’s product candidate, infigratinib, in oncology and all other indications except achondroplasia or any other skeletal dysplasias, worldwide, except for the People’s Republic of China, Hong Kong and Macau (“Greater China”), and under which QED received a co-exclusive license to co-commercialize infigratinib in the United States in the licensed indications. The QED-Helsinn License and Collaboration Agreement became effective on April 16, 2021. Upon approval by the FDA in May 2021, QED and HTU co-commercialized infigratinib in the licensed indications in the United States and shared profits and losses on a 50:50 basis. Additionally, QED and Helsinn shared global, excluding Greater China, research and development costs for infigratinib in the licensed indications at a rate of 40% for QED and 60% for Helsinn. On February 28, 2022, QED and Helsinn amended the QED-Helsinn License and Collaboration Agreement (the “Amended QED-Helsinn License and Collaboration Agreement”) effective as of March 1, 2022. Under the terms of the Amended QED-Helsinn License and Collaboration Agreement, Helsinn had an exclusive license to commercialize infigratinib in the United States and was responsible for developing, manufacturing and commercializing infigratinib in oncology indications except for achondroplasia or any other skeletal dysplasias worldwide, outside of Greater China. QED retains all rights to develop, manufacture and commercialize infigratinib in skeletal dysplasia, including achondroplasia. Pursuant to the Amended QED-Helsinn License and Collaboration Agreement, QED no longer shared in the commercialization of infigratinib in the licensed indications in the United States or was responsible for any global development costs for infigratinib in the licensed indications. Additionally, under the Amended QED-Helsinn License and Collaboration Agreement, QED was eligible to receive regulatory and sales-based milestone payments of up to $66.0 million, as well as tiered royalties in the low to mid-teens as a percentage of adjusted net sales by Helsinn of the licensed products sold worldwide, outside of Greater China. The Amended QED-Helsinn License and Collaboration Agreement also provided for a transitional period, which extended from the effective date through August 31, 2022, for which QED was contracted to assist in research and development and commercialization activities. The costs related to QED's contracted activities incurred during the transitional period were fully reimbursable by Helsinn and were due to QED subsequent to the transitional period. Helsinn also agreed to reimburse QED’s obligation to FMI described in Note 7 as part of the Amended QED-Helsinn License and Collaboration Agreement. In recording this transaction, we recognized a corresponding gain as part of “Other expense, net” for the three months ended June 30, 2022. Effective December 21, 2022, QED and Helsinn, or the Helsinn Parties, entered into a Mutual Termination Agreement or MTA, which terminates the Amended QED-Helsinn License and Collaboration Agreement and all rights and obligations thereunder. The Helsinn Parties agreed to perform certain close-out services to enable QED to pursue the development, manufacture and commercialization of infigratinib as a potential treatment of non-oncology indications, such as in achondroplasia worldwide, excluding China, Hong Kong, and Macau. As a result of the termination, QED is no longer entitled to any future regulatory or sales-based milestone payments. QED was subject to royalties on net sales of TRUSELTIQTM through March 31, 2023, at which date Helsinn no longer sells the licensed product. The FDA permanently discontinued the distribution of TRUSELTIQTM and all clinical investigations under the associated IND are discontinued. The sales of the licensed product during the three months ended March 31, 2023 was immaterial. The Helsinn Parties have developed a Close-Out Plan, as defined within the MTA. Activities within the Close-Out Plan are to be shared equally subsequent to the first $11.0 million of costs, which are the responsibility of QED. QED reached the threshold of $11.0 million in January 2023. The activities within the Close-Out Plan are expected to be completed in 2023. In accordance with the MTA, all outstanding obligations under the Amended QED-Helsinn License and Collaboration agreement related to the contracted services during the transitional period became due. This includes the reimbursable contracted research and development and commercial activities of $18.8 million and the reimbursement of QED’s obligation to FMI of $12.5 million described in Note 7. In accordance with the payment terms of the MTA, we received $15.0 million from Helsinn in December 2022 and $5.3 million in January 2023. The remaining $11.0 million is related to the remaining reimbursement of QED's obligation to FMI and is due in eleven equal monthly installments of $1.0 million commencing in February 2023, of which we have received $2.0 million as of March 31, 2023. All costs incurred subsequent to the transitional period are considered close-out costs and the responsibilities between the Helsinn Parties and are outlined within the Close-Out Plan, as defined in the MTA. For the three months ended March 31, 2023, QED has incurred $3.6 million of close-out costs of which $2.4 million is subject to 50% reimbursement from Helsinn. As of March 31, 2023, the outstanding receivable due from Helsinn was $10.1 million, of which $9.0 million related to reimbursement of QED’s obligation to FMI and $1.1 million related to reimbursable costs incurred under the Close-Out Plan. As of December 31, 2022, the outstanding receivable due from Helsinn was $16.3 million. The outstanding receivables are presented in “Receivables from licensing and collaboration agreements” within our condensed consolidated balance sheets. All close-out costs incurred, including Helsinn’s reimbursements, are recorded in "Restructuring, impairment and related charges" within our condensed consolidated statement of operations (See Note 16). The QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA were considered to be within the scope of ASC 808 as the parties are active participants and are exposed to the significant risks and rewards of the collaborative activity. The QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License and Collaboration Agreement were also partially within the scope of ASC 606 for the units of account where Helsinn is identified as a customer. For the units of account in the collaboration arrangement that do not represent a vendor-customer relationship, including the performance of collaborative research and development and commercialization services, we determined that ASC 606 is not appropriate to apply by analogy and applied a reasonable and rational accounting policy election that faithfully depicts the transfer of services to the collaboration partner over the estimated performance period. Reimbursement payments from Helsinn associated with the collaborative research and development and commercialization services are recognized as the related expense is incurred and classified as an offset to the underlying expense and excluded from the transaction price. We evaluated the terms of the QED-Helsinn License and Collaboration Agreement and identified Helsinn as a customer with the following two distinct performance obligations: (1) exclusive licenses to develop, manufacture, and commercialize the underlying product, and (2) transfer of inventory within the transitional supply period. The Amended QED-Helsinn License and Collaboration Agreement did not give rise to any additional performance obligations. All of the license revenue relating to these units of account accounted for under ASC 606 were recognized in the year ended December 31, 2021. For the unit of account that is within the scope of ASC 808 relating to collaborative research and development services, pursuant to the QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA, we have recognized Helsinn’s share of research and development expenses of $1.2 million and $6.2 million for the three months ended March 31, 2023 and 2022, respectively. For the three months ended March 31, 2023, we recognized Helsinn's share of research and development expenses of $1.2 million as a reduction to restructuring, impairment and related charges; whereas, Helsinn's share of research and development expenses of $6.2 million for the three months ended March 31, 2022, were recognized as a reduction of research and development expenses. For the unit of account that is within the scope of ASC 808 relating to commercial activities, pursuant to the QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA, we accounted for Helsinn’s share of the co-commercialization activities of nil and $1.2 million as reduction to selling, general and administrative expenses for the three months ended March 31, 2023 and 2022, respectively. License Agreement with LianBio Navire In August 2020, Navire entered into an exclusive license agreement with LianBio, or the Navire-LianBio License Agreement. Pursuant to the Navire-LianBio License Agreement, Navire granted to LianBio an exclusive, sublicensable license under the licensed patent rights and know-how to develop, manufacture and commercialize SHP2 inhibitor BBP-398, or BBP-398, for tumors driven by RAS and receptor tyrosine kinase mutations. Under the terms of the Navire-LianBio License Agreement, LianBio will receive commercial rights in China and selected Asian markets and participate in clinical development activities for BBP-398. In consideration for the rights granted to LianBio, we received a nonrefundable $8.0 million upfront payment, which we recognized as license revenue in 2020. We will also have the right to receive future development and sales milestone payments of up to $382.1 million, and tiered royalty payments from single-digit to low-teens on net sales of the product in licensed territories. We recognized $8.5 million in license revenue, representing a regulatory milestone payment in 2021. We accounted for the Navire-LianBio License Agreement under ASC 606 and identified the exclusive license as a distinct performance obligation since LianBio can benefit from the license on its own by developing and commercializing the underlying product using its own resources. In addition, we will enter into clinical and commercial supply agreements for the licensed territory. We determined that the optional right to future products under these supply agreements does not represent a material right. In July 2022, Navire and LianBio entered into a clinical supply agreement for the manufacture and supply of clinical quantities of the licensed product. No clinical supplies were provided to LianBio during the three months ended March 31, 2023 and 2022. QED In October 2019, QED entered into an exclusive license agreement with LianBio (the "QED-LianBio License Agreement"). Pursuant to the QED-LianBio License Agreement, QED granted to LianBio an exclusive, sublicensable license under the licensed patent rights and know-how to develop, manufacture and commercialize infigratinib for any and all human prophylactic and therapeutic uses in all cancer indications (including in combination with other therapies) in certain territories outside the United States. Under the QED-LianBio License Agreement, QED received a nonrefundable upfront payment of $10.0 million and is entitled to receive development and sales milestones payments of up to $132.5 million and tiered royalties on net sales ranging from the low to mid-teens. In addition, QED also received warrants which entitled QED to purchase 10% of the then-fully diluted shares of one of the subsidiaries of LianBio upon achievement of certain contingent development milestones (see Note 7). We accounted for the QED-LianBio License Agreement and the LianBio Exclusivity Agreement as a single transaction under ASC 606 and identified the exclusive license as a distinct performance obligation since LianBio can benefit from the license on its own by developing and commercializing the underlying product using its own resources. In addition, we will enter into clinical and commercial supply agreements for the licensed territory. We determined that the LianBio’s optional right to future products under these supply agreements is not considered to represent a material right. A clinical supply agreement was entered into in the fourth quarter of 2021. No clinical supplies were provided to LianBio during the three months ended March 31, 2023 and 2022. License Agreement with Alexion In September 2019, Eidos, entered into an exclusive license agreement with Alexion Pharma International Operations Unlimited Company, a subsidiary of Alexion Pharmaceuticals, Inc., or together Alexion, to develop, manufacture, and commercialize in Japan the compound known as acoramidis (previously known as AG10) and any of its various chemical forms and any pharmaceutical products containing acoramidis, or the Eidos-Alexion License Agreement. Under the agreement, Eidos received an upfront nonrefundable payment of $25.0 million. Eidos also entered into a stock purchase agreement with Alexion, under which Eidos sold to Alexion 556,173 shares of Eidos common stock at a price per share of $44.95, for an aggregate purchase price of approximately $25.0 million. The excess of the purchase price over the value of the Eidos shares, determined based on the closing price of a share of Eidos’ common stock of $41.91 as reported on Nasdaq as of the date of execution, was $1.7 million and recognized in revenue as part of the upfront payment as discussed below. Eidos is also eligible to receive $30.0 million in regulatory milestone payments subject to the achievement of regulatory milestones. Eidos will also receive royalty payments in the low-teens based on net sales of acoramidis in Japan. The royalty rate is subject to reduction if Alexion is required to obtain intellectual property rights from third parties to develop, manufacture or commercialize acoramidis in Japan, or upon the introduction of generic competition into market. Eidos accounted for the license agreement under ASC 606 and identified the exclusive license as a distinct performance obligation since Alexion can benefit from the license on its own by developing and commercializing the underlying product using its own resources. Eidos recognized the $25.0 million upfront fee and $1.7 million premium paid for Eidos’ stock for a total upfront payment of $26.7 million in license revenue upon the effective date of the license agreement in September 2019. Eidos determined that the license was a right to use its intellectual property and as of the effective date, it had provided all necessary information to Alexion to benefit from the license and the license term had begun. In addition, Eidos entered into a clinical supply agreement in July 2020 and may enter into a commercial supply agreement for the licensed territory. Eidos determined that the optional right to future products under these supply agreements is not considered to represent a material right. Eidos has shipped insignificant amounts to Alexion as part of the clinical supply agreement during the three months ended March 31, 2023 and 2022, and has recognized such amounts as license revenue. Receivables from Licensing and Collaboration Agreements Receivables from licensing and collaboration agreements represent valid claims against our partners, customers, biopharmaceutical companies including unbilled receivables and royalty payments due from third parties for licensing the Company’s technologies. Unbilled receivables include balances due from our biopharmaceutical customers related to development services and transition-related receivables that are recognized upon incurrence of the costs for the partnered programs but prior to the achievement of contractual billing rights. As of March 31, 2023 and December 31, 2022, the Company had unbilled receivables of $10.4 million and $16.8 million, respectively, of which 94.1% and 97.5%, respectively, of total unbilled receivables related to one partner. Total receivables from licensing and collaboration agreements as of March 31, 2023 and December 31, 2022 is $10.8 million and $17.1 million, respectively, and is presented as "Receivable from licensing and collaboration agreements." The Company evaluates the collectability of its receivable from licensing and collaboration agreements based on historical collection trends, the financial condition of payment partners, and external market factors and provides for an allowance for potential credit losses based on management’s best estimate of the amount of probable credit losses. As of March 31, 2023 and December 31, 2022, the Company did not have an allowance for credit losses.

On May 12, 2022, BridgeBio and our subsidiary, Navire, entered into an exclusive license development and commercialization agreement with BMS (the “Navire-BMS License Agreement”), pursuant to which Navire granted BMS exclusive rights to develop and commercialize Navire’s product candidate, BBP-398, in all indications worldwide, except for the People’s Republic of China, Macau, Hong Kong, Taiwan, Thailand, Singapore, and South Korea (the “Asia Region”). The development and commercialization of BBP-398 within the Asia Region is governed under the Navire-LianBio License Agreement (as discussed below). The Navire-BMS License Agreement expands an earlier agreement between Navire and BMS that was executed in July 2021 to study BBP-398 in a combination therapy trial to treat advanced solid tumors with KRAS mutations (the “2021 Navire-BMS Agreement”). The Navire-BMS License Agreement does not alter the terms of the 2021 Navire-BMS Agreement.

Under the terms of the Navire-BMS License Agreement, Navire was entitled to receive a non-refundable, upfront payment of $90.0 million, which Navire received in full in June 2022. Additionally, Navire is eligible to receive additional payments totaling up to approximately $815.0 million in the aggregate, subject to the achievement of development, regulatory and commercial milestones, as well as tiered royalties in the low-to-mid teens as a percentage of adjusted net sales by BMS of the licensed products sold worldwide, outside of the Asia Region. Navire will retain the option to acquire higher royalties in the United States in connection with funding a portion of development costs upon the initiation of registrational studies. Based on the terms of the Navire-BMS License Agreement, Navire will continue to lead its ongoing Phase 1 monotherapy and combination therapy trials (collectively, the “Phase 1 Trials”), and BMS will lead and fund all other development and commercialization activities. Navire is fully funding the Phase 1 trials with the exception of the combination therapy governed under the 2021 Navire-BMS Agreement. In accordance with the 2021 Navire-BMS Agreement, both parties are sharing all research and development costs equally for this trial. We have recorded all research and development costs for the Phase 1 Trials, as well as the reimbursement for the costs associated with the trial governed by the 2021 Navire-BMS Agreement within research and development in our condensed consolidated statement of operations.

We determined that the Navire-BMS License Agreement falls within the scope of ASC 606 as BMS is a customer in this arrangement, and we identified the following performance obligations in the agreement:

•

research and development services to complete the Phase 1 Trials for BBP-398 (expected to be completed in 2025).

We determined that the performance obligations outlined above are capable of being distinct and distinct with the context of the contract given such rights and activities are independent of each other. The license can be used by BMS without the research and development services. Similarly, those services provide a distinct benefit to BMS within the context of the contract, separate from the license, as the services could be provided by BMS or another third party without our assistance. We may enter into clinical and commercial supply agreements for the licensed territory. We determined that the optional right to future products under these supply agreements does not represent a material right. In March 2023, Navire and BMS entered into a clinical supply agreement for the

supply of clinical quantities of the licensed product. No clinical supplies were provided to BMS during the three months ended March 31, 2023.

We determined the initial transaction price at inception of the Navire-BMS License Agreement to be $90.0 million, which is comprised of the fixed and non-refundable upfront payment. No additional development, regulatory, or sales milestone payments are included in the transaction price, as all such payments are variable consideration that are fully constrained as of March 31, 2023. We include variable consideration in our transaction price to the extent that it is probable that it will not result in a significant revenue reversal when the uncertainty associated with the variable consideration is subsequently resolved. As part of management’s evaluation of the variable consideration, we considered numerous factors, including the fact that achievement of the milestones is outside of our control, contingent upon the success of our existing and future clinical trials, BMS’ efforts, and receipt of regulatory approval that is subject to scientific risks of success. Royalty arrangements and commercial-based milestones will be recognized when the sales occur or the milestones are achieved pursuant to the sales-based royalty exception under ASC 606 because the license is the predominant item to which the royalties or commercial-based milestones relate. We will re-evaluate the transaction price at each reporting period and as uncertain events are resolved or other changes in circumstances occur.

We allocated the transaction price of $90.0 million based on the stand-alone selling prices (“SSP”) of each of the performance obligations as follows:

The SSP for the license was determined using an approach that considered discounted, probability-weighted cash flows related to the license transferred. The SSP for the ongoing research and development services were based on estimates of the associated effort and cost of these services, adjusted for a reasonable gross profit margin that would be expected to be realized under similar contracts.

•

We recognized revenue related to the license at a point in time upon transfer of the rights and control of the license to BMS. The transfer of the rights and control of the license occurred in June 2022, thus we recognized the full amount allocated to the license and related know-how during the three months ended June 30, 2022.

•

The research and development services performance obligation consists of our completion of the Phase 1 Trials. We are recognizing revenue related to the research and development services over time using an input method to measure progress by utilizing costs incurred to-date relative to total expected costs. We expect to complete the Phase 1 Trials in 2025. Revenue recognized related to this performance obligation for the three months ended March 31, 2023 was $1.7 million.

Our condensed consolidated balance sheet as of March 31, 2023 includes a deferred revenue balance of $13.6 million ($6.7 million presented as “Deferred revenue, current portion” and $6.9 million included in “Other long-term liabilities”) related to our research and development services obligation. Our condensed consolidated balance sheet as of December 31, 2022 includes a deferred revenue balance of $15.3 million ($8.2 million presented as “Deferred revenue, current portion” and $7.1 million included in “Other long-term liabilities”) related to our research and development services obligation.

On March 29, 2021, QED entered into a license and collaboration agreement with Helsinn Healthcare S.A. (“HHC”) and Helsinn Therapeutics (U.S.), Inc. (“HTU”, and collectively with HHC, “Helsinn”) (the “QED-Helsinn License and Collaboration Agreement”), pursuant to which QED granted to HHC exclusive licenses to develop, manufacture and commercialize QED’s product candidate, infigratinib, in oncology and all other indications except achondroplasia or any other skeletal dysplasias, worldwide, except for the People’s Republic of China, Hong Kong and Macau (“Greater China”), and under which QED received a co-exclusive license to co-commercialize infigratinib in the United States in the licensed indications. The QED-Helsinn License and Collaboration Agreement became effective on April 16, 2021. Upon approval by the FDA in May 2021, QED and HTU co-commercialized infigratinib in the licensed indications in the United States and shared profits and losses on a 50:50 basis. Additionally, QED and Helsinn shared global, excluding Greater China, research and development costs for infigratinib in the licensed indications at a rate of 40% for QED and 60% for Helsinn.

On February 28, 2022, QED and Helsinn amended the QED-Helsinn License and Collaboration Agreement (the “Amended QED-Helsinn License and Collaboration Agreement”) effective as of March 1, 2022. Under the terms of the Amended QED-Helsinn License and Collaboration Agreement, Helsinn had an exclusive license to commercialize infigratinib in the United States and was responsible for developing, manufacturing and commercializing infigratinib in oncology indications except for achondroplasia or any other skeletal dysplasias worldwide, outside of Greater China. QED retains all rights to develop, manufacture and commercialize infigratinib in skeletal dysplasia, including achondroplasia.

Pursuant to the Amended QED-Helsinn License and Collaboration Agreement, QED no longer shared in the commercialization of infigratinib in the licensed indications in the United States or was responsible for any global development costs for infigratinib in the licensed indications.

Additionally, under the Amended QED-Helsinn License and Collaboration Agreement, QED was eligible to receive regulatory and sales-based milestone payments of up to $66.0 million, as well as tiered royalties in the low to mid-teens as a percentage of adjusted net sales by Helsinn of the licensed products sold worldwide, outside of Greater China.

The Amended QED-Helsinn License and Collaboration Agreement also provided for a transitional period, which extended from the effective date through August 31, 2022, for which QED was contracted to assist in research and development and commercialization activities. The costs related to QED's contracted activities incurred during the transitional period were fully reimbursable by Helsinn and were due to QED subsequent to the transitional period. Helsinn also agreed to reimburse QED’s obligation to FMI described in Note 7 as part of the Amended QED-Helsinn License and Collaboration Agreement. In recording this transaction, we recognized a corresponding gain as part of “Other expense, net” for the three months ended June 30, 2022.

Effective December 21, 2022, QED and Helsinn, or the Helsinn Parties, entered into a Mutual Termination Agreement or MTA, which terminates the Amended QED-Helsinn License and Collaboration Agreement and all rights and obligations thereunder. The Helsinn Parties agreed to perform certain close-out services to enable QED to pursue the development, manufacture and commercialization of infigratinib as a potential treatment of non-oncology indications, such as in achondroplasia worldwide, excluding China, Hong Kong, and Macau. As a result of the termination, QED is no longer entitled to any future regulatory or sales-based milestone payments. QED was subject to royalties on net sales of TRUSELTIQTM through March 31, 2023, at which date Helsinn no longer sells the licensed product. The FDA permanently discontinued the distribution of TRUSELTIQTM and all clinical investigations under the associated IND are discontinued. The sales of the licensed product during the three months ended March 31, 2023 was immaterial. The Helsinn Parties have developed a Close-Out Plan, as defined within the MTA. Activities within the Close-Out Plan are to be shared equally subsequent to the first $11.0 million of costs, which are the responsibility of QED. QED reached the threshold of $11.0 million in January 2023. The activities within the Close-Out Plan are expected to be completed in 2023.

In accordance with the MTA, all outstanding obligations under the Amended QED-Helsinn License and Collaboration agreement related to the contracted services during the transitional period became due. This includes the reimbursable contracted research and development and commercial activities of $18.8 million and the reimbursement of QED’s obligation to FMI of $12.5 million described in Note 7. In accordance with the payment terms of the MTA, we received $15.0 million from Helsinn in December 2022 and $5.3 million in January 2023. The remaining $11.0 million is related to the remaining reimbursement of QED's obligation to FMI and is due in eleven equal monthly installments of $1.0 million commencing in February 2023, of which we have received $2.0 million as of March 31, 2023. All costs incurred subsequent to the transitional period are considered close-out costs and the responsibilities between the Helsinn Parties and are outlined within the Close-Out Plan, as defined in the MTA. For the three months ended March 31, 2023, QED has incurred $3.6 million of close-out costs of which $2.4 million is subject to 50% reimbursement from Helsinn. As of March 31, 2023, the outstanding receivable due from Helsinn was $10.1 million, of which $9.0 million related to reimbursement of QED’s obligation to FMI and $1.1 million related to reimbursable costs incurred under the Close-Out Plan. As of December 31, 2022, the outstanding receivable due from Helsinn was $16.3 million. The outstanding receivables are presented in “Receivables from licensing and collaboration agreements” within our condensed consolidated balance sheets. All close-out costs incurred, including Helsinn’s reimbursements, are recorded in "Restructuring, impairment and related charges" within our condensed consolidated statement of operations (See Note 16).

The QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA were considered to be within the scope of ASC 808 as the parties are active participants and are exposed to the significant risks and rewards of the collaborative activity. The QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License and Collaboration Agreement were also partially within the scope of ASC 606 for the units of account where Helsinn is identified as a customer. For the units of account in the collaboration arrangement that do not represent a vendor-customer relationship, including the performance of collaborative research and development and commercialization services, we determined that ASC 606 is not appropriate to apply by analogy and applied a reasonable and rational accounting policy election that faithfully depicts the transfer of services to the collaboration partner over the estimated performance period. Reimbursement payments from Helsinn associated with the collaborative research and development and commercialization services are recognized as the related expense is incurred and classified as an offset to the underlying expense and excluded from the transaction price.

We evaluated the terms of the QED-Helsinn License and Collaboration Agreement and identified Helsinn as a customer with the following two distinct performance obligations: (1) exclusive licenses to develop, manufacture, and commercialize the underlying product, and (2) transfer of inventory within the transitional supply period. The Amended QED-Helsinn License and Collaboration Agreement did not give rise to any additional performance obligations. All of the license revenue relating to these units of account accounted for under ASC 606 were recognized in the year ended December 31, 2021.

For the unit of account that is within the scope of ASC 808 relating to collaborative research and development services, pursuant to the QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA, we have recognized Helsinn’s share of research and development expenses of $1.2 million and $6.2 million for the three months ended March 31, 2023 and 2022, respectively. For the three months ended March 31, 2023, we recognized Helsinn's share of research and development expenses of $1.2 million as a reduction to restructuring, impairment and related charges; whereas, Helsinn's share of research and development expenses of $6.2 million for the three months ended March 31, 2022, were recognized as a reduction of research and development expenses.

For the unit of account that is within the scope of ASC 808 relating to commercial activities, pursuant to the QED-Helsinn License and Collaboration Agreement, the Amended QED-Helsinn License Collaboration Agreement, and the MTA, we accounted for Helsinn’s share of the co-commercialization activities of nil and $1.2 million as reduction to selling, general and administrative expenses for the three months ended March 31, 2023 and 2022, respectively.

In August 2020, Navire entered into an exclusive license agreement with LianBio, or the Navire-LianBio License Agreement. Pursuant to the Navire-LianBio License Agreement, Navire granted to LianBio an exclusive, sublicensable license under the licensed patent rights and know-how to develop, manufacture and commercialize SHP2 inhibitor BBP-398, or BBP-398, for tumors driven by RAS and receptor tyrosine kinase mutations. Under the terms of the Navire-LianBio License Agreement, LianBio will receive commercial rights in China and selected Asian markets and participate in clinical development activities for BBP-398. In consideration for the rights granted to LianBio, we received a nonrefundable $8.0 million upfront payment, which we recognized as license revenue in 2020. We will also have the right to receive future development and sales milestone payments of up to $382.1 million, and tiered royalty payments from single-digit to low-teens on net sales of the product in licensed territories. We recognized $8.5 million in license revenue, representing a regulatory milestone payment in 2021.

We accounted for the Navire-LianBio License Agreement under ASC 606 and identified the exclusive license as a distinct performance obligation since LianBio can benefit from the license on its own by developing and commercializing the underlying product using its own resources. In addition, we will enter into clinical and commercial supply agreements for the licensed territory. We determined that the optional right to future products under these supply agreements does not represent a material right. In July 2022, Navire and LianBio entered into a clinical supply agreement for the manufacture and supply of clinical quantities of the licensed product. No clinical supplies were provided to LianBio during the three months ended March 31, 2023 and 2022.

In October 2019, QED entered into an exclusive license agreement with LianBio (the "QED-LianBio License Agreement"). Pursuant to the QED-LianBio License Agreement, QED granted to LianBio an exclusive, sublicensable license under the licensed patent rights and know-how to develop, manufacture and commercialize infigratinib for any and all human prophylactic and therapeutic uses in all cancer indications (including in combination with other therapies) in certain territories outside the United States. Under the QED-LianBio License Agreement, QED received a nonrefundable upfront payment of $10.0 million and is entitled to receive development and sales milestones payments of up to $132.5 million and tiered royalties on net sales ranging from the low to mid-teens. In addition, QED also received warrants which entitled QED to purchase 10% of the then-fully diluted shares of one of the subsidiaries of LianBio upon achievement of certain contingent development milestones (see Note 7).

We accounted for the QED-LianBio License Agreement and the LianBio Exclusivity Agreement as a single transaction under ASC 606 and identified the exclusive license as a distinct performance obligation since LianBio can benefit from the license on its own by developing and commercializing the underlying product using its own resources. In addition, we will enter into clinical and commercial supply agreements for the licensed territory. We determined that the LianBio’s optional right to future products under these supply agreements is not considered to represent a material right. A clinical supply agreement was entered into in the fourth quarter of 2021. No clinical supplies were provided to LianBio during the three months ended March 31, 2023 and 2022.

In September 2019, Eidos, entered into an exclusive license agreement with Alexion Pharma International Operations Unlimited Company, a subsidiary of Alexion Pharmaceuticals, Inc., or together Alexion, to develop, manufacture, and commercialize in Japan the compound known as acoramidis (previously known as AG10) and any of its various chemical forms and any pharmaceutical products containing acoramidis, or the Eidos-Alexion License Agreement. Under the agreement, Eidos received an upfront nonrefundable payment of $25.0 million.

Eidos also entered into a stock purchase agreement with Alexion, under which Eidos sold to Alexion 556,173 shares of Eidos common stock at a price per share of $44.95, for an aggregate purchase price of approximately $25.0 million. The excess of the purchase price over the value of the Eidos shares, determined based on the closing price of a share of Eidos’ common stock of $41.91 as reported on Nasdaq as of the date of execution, was $1.7 million and recognized in revenue as part of the upfront payment as discussed below.

Eidos is also eligible to receive $30.0 million in regulatory milestone payments subject to the achievement of regulatory milestones. Eidos will also receive royalty payments in the low-teens based on net sales of acoramidis in Japan. The royalty rate is subject to reduction if Alexion is required to obtain intellectual property rights from third parties to develop, manufacture or commercialize acoramidis in Japan, or upon the introduction of generic competition into market.

Eidos accounted for the license agreement under ASC 606 and identified the exclusive license as a distinct performance obligation since Alexion can benefit from the license on its own by developing and commercializing the underlying product using its own resources. Eidos recognized the $25.0 million upfront fee and $1.7 million premium paid for Eidos’ stock for a total upfront payment of $26.7 million in license revenue upon the effective date of the license agreement in September 2019. Eidos determined that the license was a right to use its intellectual property and as of the effective date, it had provided all necessary information to Alexion to benefit from the license and the license term had begun. In addition, Eidos entered into a clinical supply agreement in July 2020 and may enter into a commercial supply agreement for the licensed territory. Eidos determined that the optional right to future products under these supply agreements is not considered to represent a material right. Eidos has shipped insignificant amounts to Alexion as part of the clinical supply agreement during the three months ended March 31, 2023 and 2022, and has recognized such amounts as license revenue.

Receivables from licensing and collaboration agreements represent valid claims against our partners, customers, biopharmaceutical companies including unbilled receivables and royalty payments due from third parties for licensing the Company’s technologies. Unbilled receivables include balances due from our biopharmaceutical customers related to development services and transition-related receivables that are recognized upon incurrence of the costs for the partnered programs but prior to the achievement of contractual billing rights. As of March 31, 2023 and December 31, 2022, the Company had unbilled receivables of $10.4 million and $16.8 million, respectively, of which 94.1% and 97.5%, respectively, of total unbilled receivables related to one partner. Total receivables from licensing and collaboration agreements as of March 31, 2023 and December 31, 2022 is $10.8 million and $17.1 million, respectively, and is presented as "Receivable from licensing and collaboration agreements."

The Company evaluates the collectability of its receivable from licensing and collaboration agreements based on historical collection trends, the financial condition of payment partners, and external market factors and provides for an allowance for potential credit losses based on management’s best estimate of the amount of probable credit losses. As of March 31, 2023 and December 31, 2022, the Company did not have an allowance for credit losses.
