IDEAYA Biosciences to Initiate New Drug Application Submission from the Darovasertib OptimUM-02 Trial under the Oncology Center of Excellence Real-time Oncology Review (RTOR) Program
IDEAYA Biosciences announced that the FDA has agreed to review its New Drug Application (NDA) for darovasertib in combination with crizotinib for patients with first-line HLA*A2-negative metastatic uveal melanoma (mUM) under the Real-Time Oncology Review (RTOR) program. The decision follows positive topline data from the Phase 2/3 OptimUM-02 trial, which met its primary endpoint by significantly improving progression-free survival. The company plans to initiate the RTOR submission process in May, with the full NDA filing expected in the second half of 2026, aiming to expedite the availability of this potential new treatment.
