Verastem Oncology Provides Preliminary Fourth Quarter and 2025 Revenue and Business Updates and Outlines 2026 Strategic Priorities for Novel Portfolio Targeting RAS/MAPK Pathway-Driven Cancers
BOSTON--( BUSINESS WIRE)--Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced preliminary, unaudited fourth quarter and full year 2025 net product revenues for AVMAPKI™ FAKZYNJA™ CO-PACK, business updates, and 2026 priorities.
"2025 was a transformative year for Verastem Oncology and the patients we serve. We transitioned to a commercial-stage company with the launch of AVMAPKI FAKZYNJA CO-PACK, the first treatment specifically approved by the FDA for KRAS-mutated recurrent low-grade serous ovarian cancer (LGSOC). We also advanced multiple clinical programs across several RAS/MAPK pathway-driven solid tumor cancers,” said Dan Paterson, president and chief executive officer at Verastem Oncology. “In 2026, we are well-positioned to drive sustainable growth with our successful commercial launch and to accelerate our clinical path for VS-7375, our potential best-in-class oral KRAS G12D (ON/OFF) inhibitor, with several important data readouts and preparations for potential registration-directed clinical trials.”

About AVMAPKI and FAKZYNJA Combination Therapy
AVMAPKI (avutometinib) inhibits MEK kinase activity while also blocking the compensatory reactivation of MEK by upstream RAF. RAF and MEK proteins are regulators of the RAS/RAF/MEK/ERK (MAPK) pathway. Blocking RAF and/or MEK activates FAK, a key mediator of drug resistance. FAKZYNJA (defactinib) is a FAK inhibitor and together, the avutometinib and defactinib combination was designed to provide a more complete blockade of the signaling that drives the growth and drug resistance of RAS/MAPK pathway-dependent tumors.
The U.S. Food and Drug Administration (FDA) approved AVMAPKI™ FAKZYNJA™ CO-PACK (avutometinib capsules; defactinib tablets) for the treatment of adult patients with KRAS-mutated recurrent LGSOC who have received prior systemic therapy on May 8, 2025. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. Verastem is conducting RAMP 301 (GOG-3097/ENGOT-ov81/GTG-UK) (NCT06072781), an international Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent low-grade serous ovarian cancer (LGSOC) with and without a KRAS mutation. Verastem is also evaluating avutometinib plus defactinib with standard-of-care chemotherapy as a potential treatment in the first-line for patients with advanced pancreatic cancer (RAMP 205; NCT05669482). Avutometinib and defactinib are not approved by the FDA or any other regulatory authority, either in combination or with other therapies, for any of these investigative uses. Neither avutometinib nor defactinib are approved by the FDA or any other regulatory authority on a stand-alone basis for any use.

About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor
VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. VS-7375 is the lead program from the Verastem Oncology discovery and development collaboration with GenFleet Therapeutics. Verastem initiated VS-7375-101, an international Phase 1/2 clinical trial, in June of 2025 in the U.S., that is evaluating the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. Verastem announced in April 2025 that the U.S. Investigational New Drug (IND) application for VS-7375 was cleared.
About the GenFleet Therapeutics Collaboration
The collaboration with GenFleet Therapeutics aims to advance three oncology discovery programs related to RAS/MAPK pathway-driven cancers. The collaboration provides Verastem with an exclusive option to obtain a license for each of the three compounds in the collaboration after the successful completion of pre-determined milestones in a Phase 1 trial. Verastem selected VS-7375 (also known as GFH375), an oral KRAS G12D (ON/OFF) inhibitor, as its lead program in December 2023 and the license for VS-7375 that was exercised in January 2025 is the first one from this collaboration. The licenses would give Verastem development and commercialization rights outside the GenFleet markets of mainland China, Hong Kong, Macau, and Taiwan.
