IDEAYA Biosciences Receives Fast Track Designation for Darovasertib Combination Therapy with Crizotinib for the Treatment of Metastatic Uveal Melanoma

IDEAYA Biosciences, Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to IDEAYA’s development program investigating darovasertib, a potential first-in-class protein kinase C (PKC) inhibitor, for use in combination with crizotinib, an investigational cMET inhibitor, for the treatment of adult patients with metastatic uveal melanoma.

“We are extremely pleased to receive the U.S. FDA Fast Track designation as we prepare to initiate a potential Phase 2/3 registrational trial to evaluate the darovasertib and crizotinib combination in patients with MUM. The Fast Track designation acknowledges MUM as a serious condition and the potential for the darovasertib / crizotinib combination to treat this unmet medical need,” said Dr. Darrin Beaupre, Senior Vice President and Chief Medical Officer at IDEAYA Biosciences.

Fast Track is a U.S. FDA process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. Under the Fast Track designation, the darovasertib / crizotinib development program in MUM is eligible for various expedited regulatory review processes, including generally more frequent FDA interactions (e.g., meetings, written communications), potential eligibility for rolling review of a New Drug Application (NDA) and potential accelerated approval and priority review of an NDA.

Darovasertib was previously also designated as an Orphan Drug by the U.S. FDA in Uveal Melanoma (UM), including in MUM, entitling IDEAYA to certain potential tax credits, exemptions from user fees, and statutory marketing exclusivity.

IDEAYA is targeting initiation of a potential registration-enabling trial for the darovasertib and crizotinib combination in MUM in Q1 2023, subject to FDA feedback and guidance.

IDEAYA is also planning to initiate a company-sponsored Phase 1 clinical trial in Q4 2022 to evaluate darovasertib monotherapy in neoadjuvant UM patients. The preliminary development approach contemplates clinical endpoints such as organ preservation and/or vision preservation proximal to primary interventional treatments. Additional information on the company’s plans to evaluate darovasertib, including scientific insights and clinical development opportunities in the neoadjuvant setting, will be highlighted in an Investor R&D Day webcast being hosted by IDEAYA on December 12, 2022, at 8:00 am – 9:30 am ET.
