Research and Development Collaborations | Research and Development Collaborations (a)Aurigene The Company is party to an exclusive collaboration agreement with Aurigene for the discovery, development and commercialization of small molecule compounds in the areas of immuno-oncology and selected precision oncology targets. Under the collaboration agreement, Aurigene granted the Company an option to obtain exclusive, royalty-bearing licenses to relevant Aurigene technology to develop, manufacture and commercialize products containing certain of such compounds anywhere in the world, except for India and Russia, which are territories retained by Aurigene. Additionally, Aurigene retains the rights to develop and commercialize CA-170 worldwide, and the Company is entitled to receive royalty payments on potential future sales of CA-170 at percentage rates ranging from the high single digits up to 10%, subject to specified reductions. As of March 31, 2026, the Company has licensed the following programs under the collaboration: 1.IRAK4 Program - a precision oncology program of small molecule inhibitors of IRAK4. The development candidate is emavusertib. 2.PD1/TIM3 Program - an immuno-oncology program of small molecule antagonists of PD1 and TIM3 immune checkpoint pathways. The development candidate is CA-327. 3.An immuno-oncology program. For each of the IRAK4, PD1/TIM3, and the immuno-oncology program, the Company is obligated to use commercially reasonable efforts to develop, obtain regulatory approval for, and commercialize at least one product in each of the U.S., specified countries in the European Union and Japan. Aurigene is obligated to use commercially reasonable efforts to perform its obligations under the development plan for its licensed programs. For each of the IRAK4, PD1/TIM3, and the immuno-oncology program, the Company has remaining unpaid or unwaived payment obligations of $42.5 million per program, related to regulatory approval and commercial sales milestones, plus specified additional payments for approvals for additional indications, if any. (b)Genentech In June 2003, the Company licensed its proprietary Hedgehog pathway antagonist technologies to Genentech for human therapeutic use. Erivedge is being commercialized by Genentech in the U.S. and by Genentech’s parent company, Roche, outside of the U.S. for the treatment of advanced BCC. In November 2025, the Company sold Erivedge to TPC Investments Royalty LLC, a limited liability company managed by Oberland Capital Management, LLC. Following the sale of Erivedge, the Company is no longer entitled to revenues under the Genentech License Agreement. Pursuant to the collaboration agreement, the Company was entitled to a royalty on net sales of Erivedge that ranged from 5% to 7.5%. The royalty rate applicable to Erivedge was decreased by 2% on a country-by-country basis in certain specified circumstances. The Company recognized $2.4 million in royalty revenues under the Genentech collaboration during the three months ended March 31, 2025. Cost of royalties comprised payments to university licensors and was not material for the three months ended March 31, 2025. Prior to the sale of Erivedge, a significant portion of royalty revenues received from Genentech on net sales of Erivedge was paid to Oberland pursuant to the Oberland Purchase Agreement.
