IDEAYA Biosciences Paves the Way for Innovative Uveal Melanoma Treatment
IDEAYA Biosciences Advances Stage for Darovasertib in Uveal Melanoma
IDEAYA Biosciences, Inc. (NASDAQ: IDYA), known for its dedication to precision medicine in oncology, recently announced a promising development regarding its drug darovasertib. The company is preparing to initiate a Phase 3 randomized registrational trial aimed at using darovasertib as a neoadjuvant therapy for primary uveal melanoma (UM) in the first half of 2025.
FDA Type D Meeting Outcomes
The results from the FDA Type D meeting have laid the groundwork for the trial design, incorporating essential feedback that aligns with the safety and efficacy objectives for darovasertib. This meeting endorsed eye preservation as a primary endpoint for patients undergoing enucleation, as well as eye-related clinical outcome measures for those treated with plaque brachytherapy (PB).
Trial Design Insights
In the upcoming Phase 3 trial, IDEAYA plans to enroll approximately 520 patients, divided into two cohorts: 120 patients eligible for enucleation and 400 patients suitable for plaque brachytherapy. The trial will utilize a 2:1 randomization strategy for assigning patients to either the darovasertib treatment group or control group.
Key Endpoints and Predictive Measures
The trial aims to exceed a lower bound eye preservation rate of 10% with a 95% confidence interval for the enucleation cohort. Additionally, for the plaque brachytherapy cohort, the primary endpoint revolves around measuring vision loss from the baseline randomization to the completion of PB treatment as determined by best-corrected visual acuity (BCVA).
Darovasertib’s Potential in Oncology
Darovasertib, a selective protein kinase C (PKC) inhibitor, is being developed for treating both primary UM and metastatic uveal melanoma (MUM). Its notable recognition by the FDA, including Breakthrough Therapy and Orphan Drug designations, underscores its potential. A clinical trial is already in progress combining darovasertib with crizotinib for adult patients with MUM, illustrating IDEAYA's commitment to addressing unmet medical needs in this space.
Prospective Pathways and Future Endeavors
As IDEAYA moves forward, they plan to submit the data from the enucleation cohort for regulatory review well ahead of the PB cohort, contingent on the maturity of event-free survival data across both groups. The trial will establish a clear dosing strategy, with 300mg BID set as the standard for evaluation.
