IDEAYA Biosciences Achieves Groundbreaking Survival Data in Uveal Melanoma Trials
IDEAYA Biosciences, Inc., a leader in precision oncology, recently unveiled compelling findings from its Phase 1/2 clinical trial, titled OptimUM-01, which evaluated the combination treatment of darovasertib, an investigational PKC inhibitor, and crizotinib, a c-MET inhibitor approved by Pfizer, for patients battling metastatic uveal melanoma (mUM). This study, set to be discussed at the 2025 Society for Melanoma Research Congress in Amsterdam, is particularly noteworthy as it reported a median overall survival (OS) of 21.1 months for participants undergoing this innovative treatment approach.
Historically, patients diagnosed with metastatic uveal melanoma have a grim prognosis, with previous studies indicating an approximate OS of merely 12 months. Leaping beyond these expectations, the recent trial included 44 first-line mUM patients with a follow-up duration averaging 25 months as of the cut-off date in late May 2025. The results not only highlight the survival advantage brought about by the darovasertib and crizotinib combination, but also a median progression-free survival (PFS) achieving 7.0 months, as well as a confirmed overall response rate (ORR) of 34%. All patients reported stable disease, contributing to an impressive disease control rate (DCR) of 90%.
The combination therapy demonstrated manageable safety profiles, with the most common treatment-related adverse events (TRAEs) including diarrhea, nausea, and fatigue. Yet, the study observed no Grade 3 or higher TRAEs with incidences greater than 5%, indicating a commendable safety record. Dr. Darrin Beaupre, Chief Medical Officer at IDEAYA, expressed strong optimism regarding these findings, emphasizing the combination's potential in transforming treatment strategies for metastatic uveal melanoma.
The optimism surrounding these results is further supported by Dr. Meredith McKean from the Sarah Cannon Research Institute, who noted the significant clinical benefits demonstrated in this patient population. The ongoing research will continue into the registrational Phase 2/3 trial known as OptimUM-02, targeting first-line HLA*A201-negative mUM patients, with median PFS data expected to be reported between late 2025 and early 2026. This data may bolster IDEAYA’s efforts for potential accelerated approval from regulatory authorities.
As a rare and aggressive form of ocular cancer, metastatic uveal melanoma poses unique challenges in treatment and patient care. IDEAYA Biosciences stands at the forefront, aiming to revolutionize therapies for this condition through bitargeted approaches that could minimize risks while maximizing patient outcomes. Their commitment to identifying and developing precision medicines is evident through their diversified pipeline comprising targeted synthetic lethality and antibody-drug conjugate therapies. The decisive findings from the OptimUM-01 trial underscore the innovative spirit at IDEAYA as they endeavor to reshape the landscape of treatment for patients afflicted by this aggressive cancer form. The presentation of these significant findings at the Society for Melanoma Research Congress marks a pivotal point in the ongoing fight against uveal melanoma, aiming to pave the way for future breakthroughs in cancer therapy.
