SURESNES, France and SOUTH SAN FRANCISCO, Calif., Sept. 2, 2025 /PRNewswire/ -- Servier, an independent international pharmaceutical group governed by a foundation, and IDEAYA Biosciences, Inc. (NASDAQ: IDYA), a leading precision medicine oncology company, today announced an exclusive license agreement to bring darovasertib, a promising treatment for a rare eye cancer, to patients worldwide. Under the agreement, Servier obtains the regulatory and commercial rights for darovasertib in all territories outside the United States. IDEAYA retains its rights for darovasertib in the United States. Darovasertib, a potent and selective protein kinase C (PKC) inhibitor, is being developed to broadly address primary and metastatic uveal melanoma (UM).

"At Servier, our mission is to deliver transformative therapies to patients with significant needs. Our collaboration with IDEAYA is a significant step to make darovasertib the potential first-in-class treatment available to uveal melanoma patients worldwide," said Arnaud Lallouette, Executive Vice-President Global Medical & Patient Affairs at Servier. "Today, there are limited treatment options and there is an urgent need to improve patient outcomes. We look forward to leveraging our global oncology network, and expertise in developing oncology targeted therapies, to make this groundbreaking treatment accessible to patients across the globe."

"Darovasertib addresses a significant unmet need, and we are thrilled to partner with Servier to globally develop it as a potential standard-of-care for uveal melanoma patients worldwide. This partnership enables IDEAYA and Servier to accelerate the global development for darovasertib across three Phase 3 registrational trials, aiming to improve patient outcomes in the neoadjuvant, adjuvant and metastatic settings," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences. 

"We believe Servier's global footprint and proven track record in bringing novel therapies to patients in Europe and other key territories outside of the U.S. will ensure that this potentially life-changing treatment reaches as many patients as possible," said Daniel Simon, Chief Business Officer, IDEAYA Biosciences.

Darovasertib is currently being evaluated in multiple global clinical trials. These include a Phase 2/3 randomized trial evaluating darovasertib in combination with crizotinib in first line patients with HLA-A2-negative metastatic uveal melanoma (UM), for which the median progression free survival readout is anticipated from year-end 2025 to Q1 2026, and a Phase 3 randomized trial evaluating neoadjuvant darovasertib as a monotherapy in primary UM, independent of HLA status. IDEAYA and Servier will target to launch a global Phase 3 randomized clinical trial in 2026 to evaluate adjuvant darovasertib in primary UM, also in both HLA-A2-negative and -positive patients.

Uveal melanoma (UM) is a rare and aggressive form of eye cancer that originates in the uveal tract, which includes the iris, ciliary body, and choroid. Despite its rarity, it poses significant risks due to its potential to metastasize to other parts of the body, particularly the liver. Current treatment options include radiation therapy, surgical removal of the tumor, or removal of the eye (enucleation) in severe cases.

Darovasertib has received US FDA (Food and Drug Administration) Breakthrough Therapy Designation as neoadjuvant therapy in enucleation recommended primary UM and Fast Track designation for darovasertib in combination with crizotinib in adult patients with metastatic UM. Darovasertib has also been designated as an Orphan Drug by the US FDA in UM, including in metastatic UM.

Under the terms of the agreement, IDEAYA will receive an upfront payment of $210 million, and be eligible for up to $100 million in regulatory approval-based milestone payments and up to $220 million in commercial milestone payments, as well as double-digit royalties on net sales in all territories outside of the United States. Servier will be responsible for the regulatory and commercial activities for darovasertib in all territories outside the United States. IDEAYA and Servier will collaborate on the development of darovasertib and share the associated costs.
