IDEAYA Biosciences Announces ESMO 2026 Presentations for Darovasertib and IDE849 Clinical Programs

SOUTH SAN FRANCISCO, Calif. , July 17, 2026 / PRNewswire / -- IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a leading precision medicine oncology company, today announced three abstract presentations at the 2026 European Society of Medical Oncology (ESMO) meeting, taking place on October 23-27 in Madrid, Spain. The presentations will feature data updates from across IDEAYA's clinical pipeline, including multiple ongoing trials of darovasertib in uveal melanoma, including the registrational Phase 2/3 OptimUM-02 trial in HLA*A2:01-negative metastatic UM (mUM), the Phase 2 OptimUM-01 trial in HLA*A2:01-positive mUM, and the Phase 2 OptimUM-09 trial in the neoadjuvant setting of primary uveal melanoma. IDEAYA's partner, Hengrui Pharma, will also present clinical trial results from their Phase 1 study of IDE849 (SHR-4849) being conducted in China in patients with small cell lung carcinoma (SCLC) and other neuroendocrine carcinomas (NECs).

"We're excited to showcase the breadth of our pipeline progress at this year's ESMO Congress. Additional data from our ongoing trials in both metastatic and neoadjuvant uveal melanoma, namely OptimUM-02, OptimUM-01 and OptimUM-09, bolster our conviction in the potential of darovasertib to become an important new treatment option across the uveal melanoma patient journey. We also hope to highlight the potential best-in-class profile of IDE849, our Phase 1 DLL3 TOP1 ADC, in SCLC and NECs, where monotherapy and combination trials are ongoing and the program's first registrational trial is targeted to initiate by year-end by partner Hengrui in China and in our regions, including the US," said Dr. Darrin Beaupre, Chief Medical Officer, IDEAYA Biosciences.
