Recurrent low-grade serous ovarian cancer is a rare cancer with no FDA-approved treatments

Company seeking accelerated approval and priority review of its NDA submission in patients with KRAS mutant low-grade serous ovarian cancer; FDA filing decision expected before the end of 2024 with potential for FDA approval decision by mid-2025

Verastem Oncology (NASDAQ:VSTM), a biopharmaceutical company committed to advancing new medicines for patients with cancer, today announced that the Company has completed its rolling New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for the investigational and potential first-in-class combination of avutometinib, an oral RAF/MEK clamp, and defactinib, an oral selective FAK inhibitor, for adults with recurrent KRAS mutant low-grade serous ovarian cancer (LGSOC), who received at least one prior systemic therapy.

There are currently no FDA-approved treatments specifically for LGSOC, a rare and distinct ovarian cancer that differs from high-grade serous ovarian cancer in both its biology and behavior. Verastem submitted the NDA under the FDA's Accelerated Approval pathway and requested a Priority Review based on the combination's potential to address significant unmet medical need among patients with recurrent LGSOC. If granted, the FDA review will be completed within six months following the 60-day filing period. If approved, Verastem expects that avutometinib plus defactinib will be the first-ever FDA-approved treatment specifically for adult patients in the United States with recurrent KRAS mutant LGSOC.
