In October 2024, we earned a $7.0 million milestone payment for the IND clearance of IDE275 (GSK 959), a potential first-in-class WRN inhibitor. Research and Development Expenses Research and development expenses increased by $165.2 million, or 128%, during the year ended December 31, 2024 compared to the year ended December 31, 2023.
We also recognized revenue related to amounts allocated to the two research and development service milestones over time, as the underlying services are performed over the period through the completion of program development activities. 100 Pursuant to the GSK Collaboration Agreement, in October 2024, we earned a $7.0 million milestone payment for the IND clearance of IDE275 (GSK 959), a potential first-in-class WRN inhibitor.
We completed all performance obligations related to the upfront payment under the GSK Collaboration Agreement as of December 31, 2023 for the Pol Theta and WRN programs. Future collaboration revenue recognized under the GSK Collaboration Agreement is related to milestone payments as they are earned.
We completed all performance obligations under the GSK Collaboration Agreement as of December 31, 2023 for the Pol Theta and WRN programs. In December 2025, GSK notified us of its intention to terminate the Collaboration, Option and License Agreement, dated June 15, 2020, which will be effective 90 days following the date of GSK’s notice, or March 9, 2026.
In December 2024, we announced the recommendation of a move-forward dose and the completion of the Part 2a dose optimization for the potential registration-enabling Phase 2/3 trial evaluating the combination of darovasertib and crizotinib in the first-line, or 1L setting in patients with HLA-A2(-) MUM.
We are evaluating darovasertib in combination with crizotinib, Pfizer’s oral c-MET inhibitor, in a potentially registration-enabling, Phase 2/3 trial (OptimUM-02) for human leukocyte antigen-A*02:01 negative (HLA*A2(-)), patients with first line (1L) mUM. We expect to report topline data, including progression free survival (PFS) data, from this trial in the first quarter of 2026.
We are focusing substantially all of our resources on the development of our product candidates.
These expenses are primarily for services provided by external consultants, CMOs and CROs. (2) Other research and development expenses include manufacturing and clinical trial costs for preclinical and earlier clinical stage programs.
