Bull case
Verastem is viewed favorably because avutometinib plus defactinib has shown strong and durable activity in LGSOC, including an 18% confirmed ORR and 13-month median PFS in KRAS wild-type patients, supporting potential label expansion beyond the current KRAS-mutant setting. The company’s dual RAF/MEK and FAK inhibition has a compelling biological rationale in RAS-driven resistance biology, while the franchise could benefit from a broad addressable market of roughly 1K-2K new LGSOC patients per year and data showing 64% of responders maintained responses at two years. Verastem is also supported by VS-7375, which has early efficacy and a cleaner safety profile versus historical competitors, with 190+ patients enrolled across TARGET-D 101 and registrational studies advancing toward completion expected by YE26, reinforcing the case for meaningful future commercialization upside.
