Kyowa Kirin Collaboration and License Agreement [Abstract]
Kyowa Kirin Collaboration and License Agreement	7. Kyowa Kirin Collaboration and License Agreement On November 20, 2024, we and Kyowa Kirin Co., Ltd. and Kyowa Kirin, Inc., or together Kyowa Kirin, entered into a collaboration and license agreement, or the Kyowa License Agreement, to develop and commercialize globally our product candidate, ziftomenib, a potent, selective oral menin inhibitor, for the treatment, diagnosis and prevention of acute myeloid leukemia, or AML, and other hematologic malignancies, and if Kyowa Kirin exercises the Field Expansion Option (as defined below), the treatment, diagnosis and prevention of all cancers, or collectively the Field. We have the right and responsibility to lead all development, manufacturing, and regulatory activities and commercial strategy development for ziftomenib in the United States based on a development plan and budget mutually agreed upon with Kyowa Kirin and under the oversight of a joint steering committee and applicable subcommittees. In accordance with the development plan, we are conducting multiple Phase 2 and Phase 3 clinical trials of ziftomenib, as a monotherapy and in combination with other therapies, in AML and other hematologic malignancies to support regulatory approvals of ziftomenib in the United States. We and Kyowa Kirin will continue to conduct the activities required by the development plan as allocated to us by such plan. We are responsible for funding the specified development activities set forth in the initial development plan that are planned to be conducted prior to the end of 2028, and we will share with Kyowa Kirin equally (50/50) all development costs for all other development activities in the United States that are to be included in the development plan, including clinical trials and post-marketing commitments that are reasonably necessary for obtaining or maintaining regulatory approval of ziftomenib in the United States, or Development Services. In addition, we will conduct certain specified development and manufacturing activities outside the scope of the development plan at our sole cost and expense. Following regulatory approval, we will commercialize and record sales of ziftomenib in the United States, and Kyowa Kirin will have the right and responsibility to co-promote ziftomenib for up to a certain percentage of the details in the United States. In collaboration with Kyowa Kirin, we will perform commercialization activities, or Commercialization Services, in accordance with a co-created U.S. territory commercialization plan and budget. The parties will share equally all costs and expenses for, and profits or losses from, the commercialization of ziftomenib in the United States. On June 27, 2025, we entered into a co-promotion and medical affairs agreement with Kyowa Kirin, Inc., or the Kyowa Co-Promotion Agreement, to co-promote and perform medical affairs activities with respect to ziftomenib for the treatment of patients with AML and other hematologic malignancies in the United States, and solely if Kyowa Kirin exercises its field expansion option under the Kyowa License Agreement, all approved indications for ziftomenib in the United States that are licensed under the Kyowa License Agreement. The Kyowa Co-Promotion Agreement was determined to be a separate contract from the Kyowa License Agreement for purposes of revenue recognition and reporting. Kyowa Kirin has the right and responsibility to lead development, regulatory activities and commercialization for ziftomenib outside of the United States and is solely responsible for the conduct and funding of such activities that are specific to the exploitation of ziftomenib outside of the United States. Following regulatory approval, Kyowa Kirin will be solely responsible for the conduct and funding of commercialization of ziftomenib outside of the United States (including recording sales). Kyowa Kirin is required to use commercially reasonable efforts to conduct the development of ziftomenib outside the United States in accordance with an ex-U.S. territory development plan, to achieve the development milestone events outside the United States that entitle us to receive corresponding development milestone payments, and to commercialize ziftomenib in each country outside of the United States where it has received regulatory approval. Development and commercialization activities outside of the United States will also be under the oversight of the joint steering committee and applicable subcommittees. We are responsible for the global manufacture and supply of ziftomenib necessary for the development and commercialization activities described above, pursuant to the terms of a clinical supply agreement entered into with Kyowa Kirin Co., Ltd. effective as of March 31, 2025, or the Kyowa Clinical Supply Agreement, which was determined to be a separate contract from the Kyowa License Agreement for purposes of revenue recognition and reporting. Kyowa Kirin has the right to request that we conduct a manufacturing technology transfer and to take over the responsibility of commercial supply of ziftomenib outside the United States. We granted Kyowa Kirin an exclusive license to enable or allow Kyowa Kirin to develop, manufacture, and commercialize ziftomenib within the Field outside of the United States, or the License. We also granted Kyowa Kirin rights to fulfill their responsibilities related to the Development Services and Commercialization Services as part of the joint development and commercialization of ziftomenib in the United States. In addition, Kyowa Kirin has an option to expand the licensed Field to include the development and commercialization of ziftomenib in gastrointestinal stromal tumors, or GIST, and other solid tumor indications, or Field Expansion Option, which option can be exercised within a specified time period after receipt of clinical data from the planned proof-of-concept study evaluating ziftomenib and imatinib in patients with advanced GIST who are not successfully treated with imatinib. After Kyowa Kirin’s exercise of the Field Expansion Option, the Field would include the treatment, diagnosis and prevention of all cancers, including GIST and other solid tumors. In exchange for the License and Kyowa Kirin’s rights to participate in the development and commercialization activities described above, we received an upfront payment of $330.0 million. We are eligible to receive, if Kyowa Kirin exercises the Field Expansion Option, up to an aggregate of $1.161 billion in development, regulatory, commercial milestone and additional upfront payments for the existing Field and the expanded Field, totaling up to $1.491 billion in upfront and milestone payments in the aggregate. We are also eligible to receive tiered double-digit royalties on sales of ziftomenib outside of the United States on a country-by-country basis until the latest of expiration of the last-to-expire valid claim of our patent rights licensed to Kyowa Kirin in such country, expiration of the last-to-expire regulatory exclusivity in such country and ten years after first commercial sale in such country, or the Royalty Term. The Kyowa License Agreement will remain in effect in the United States until the latest of expiration of all valid claims of our patent rights licensed to Kyowa Kirin, expiration of the last-to-expire regulatory exclusivity or ten years after first commercial sale. The Kyowa License Agreement will remain in effect outside the United States until the expiration of the last-to-expire Royalty Term. Either party may terminate the Kyowa License Agreement for uncured material breach by or insolvency of the other party. Kyowa Kirin may terminate the Agreement for convenience upon twelve months’ prior written notice. In addition, Kyowa Kirin has the right to terminate the Kyowa License Agreement with a shorter specified notice period upon the occurrence of a material adverse regulatory event or certain other specified events. We may terminate the Kyowa License Agreement if Kyowa Kirin or any of its affiliates or sublicensees challenges the validity or enforceability of any of the patent rights licensed to Kyowa Kirin by us. Based on our analysis of the key terms and activities required by the Kyowa License Agreement summarized above and given the involvement by both parties, we assessed the criteria under Topic 808 and concluded that both parties participate in a joint operating activity, are active participants, and are exposed to significant risks and rewards dependent on the commercial success of the activities. Therefore, the Kyowa License Agreement was determined to be within the scope of Topic 808. We evaluated each of the required promised goods and services and determined the Kyowa License Agreement contains multiple units of account comprised of the License, Development Services related to monotherapy and in combination with other therapies, and Commercialization Services. The License is a unit of account under the scope of Topic 606 as it is reflective of a typical vendor-customer relationship, while the Development Services and Commercialization Services are under the scope of Topic 808 due to the joint participation in the services being performed and these services not being reflective of a typical vendor-customer relationship. However, we determined that Topic 606 was the most appropriate accounting model to apply by analogy to the recognition and measurement of these units of account. As of September 30, 2025, we determined the transaction price to be $405.0 million, comprised of the upfront fixed payment of $330.0 million and $75.0 million in unconstrained milestones. All other variable consideration related to milestones have been fully constrained due to development, regulatory, or other factors that caused us to determine that it was not probable that a significant reversal of revenue would not occur as of September 30, 2025. We will recognize any royalties or sales-based milestones related to the License granted to Kyowa Kirin when the associated sales occur, and relevant sales-based thresholds are met. As of September 30, 2025, no royalties or sales-based milestones have been recognized. We allocated the transaction price to each unit of account based on their relative stand-alone selling price. Variable consideration that relates specifically to our efforts to satisfy specific performance obligations, such as certain milestones, is allocated entirely to those performance obligations. Other components of variable consideration that do not relate specifically to our efforts to satisfy specific performance obligations are allocated based on the relative stand-alone selling price. We are entitled to cost-sharing reimbursements from Kyowa Kirin for certain development and commercialization activities we perform and determined that such reimbursements are specifically related to our efforts to satisfy the respective performance obligations while satisfying the overall allocation objective required by Topic 606. We recognized $49.8 million of revenue allocated to the License at a point in time and upon transfer in November 2024. As of September 30, 2025, consideration allocated to the Development Services for monotherapy and in combination with other therapies was $57.6 million and $120.2 million, respectively, and to Commercialization Services was $177.4 million. The allocated consideration is being recognized over time using a cost-to-cost measure of progress. We estimated the total cost expected to perform the required activities and measured the progress towards completion of each of these obligations at the reporting period. For the three and nine months ended September 30, 2025, we recognized $7.0 million and $19.8 million of revenue from Development Services for monotherapy, respectively, $5.1 million and $10.4 million of revenue from Development Services in combination with other therapies, respectively, and $2.3 million and $5.3 million of revenue from Commercialization Services, respectively. For the three and nine months ended September 30, 2025, we recognized $5.9 million and $14.1 million of revenue, respectively, from cost-share reimbursements related to the sharing of profits and losses, and the related receivable was included in receivable from contracts with collaborators on the unaudited condensed balance sheet as of September 30, 2025. For each of the three and nine months ended September 30, 2025, we also recognized $0.5 million of revenue pursuant to services performed under the Kyowa Clinical Supply Agreement. As of September 30, 2025, the contract liability amount of $317.6 million represents the aggregate transaction price allocated to performance obligations that are unsatisfied under the Kyowa License Agreement, $48.7 million was classified as current contract liabilities, which represents the portion of the Development Services and Commercialization Services expected to be provided over the next year, and the remaining contract liability balance of $268.9 million was classified as long-term contract liabilities.
