IDE849 survival data support diversification; darovasertib NDA completion remains the next milestone

IDEAYA Biosciences is a clinical-stage oncology company developing precision cancer drugs, led by darovasertib for metastatic uveal melanoma; none are approved.

IDEAYA's case rests on darovasertib plus crizotinib in first-line HLA-A*02:01-negative metastatic uveal melanoma. OptimUM-02 met its primary endpoint; NDA completion under RTOR remains expected in the second half of 2026. IDE849's preliminary survival results support diversification, with randomized global registrational trials planned in post-Imdelltra ES-SCLC and NEC. Earlier MTAP programs add options. Cash, equivalents and securities were ~$1.24 billion as of June 30, 2026; management guides into 2030 based on its current operating plan.
