- FDA Approval: Verastem Oncology's AVMAPKI®FAKZYNJA®CO-PACK received accelerated FDA approval on May 8, 2025, specifically designed for adult patients with KRAS-mutated recurrent low-grade serous ovarian cancer who have undergone prior systemic therapy, marking a significant advancement in treatment options.
- Patient Support Initiative: The newly launched 'Reimagine Recurrent LGSOC' campaign aims to provide emotional resonance and practical information for both patients and healthcare professionals, helping patients better manage their condition and set treatment expectations, thereby enhancing their quality of life.
- Market Demand Response: LGSOC is a rare cancer with a high recurrence rate, with approximately 30% of patients harboring KRAS mutations; Verastem's treatment not only fills a critical gap in this therapeutic area but also offers renewed hope for patients, potentially driving the company's growth in the biopharmaceutical market.
- Clinical Trial Plans: Verastem is conducting the international Phase 3 confirmatory trial RAMP 301 to evaluate the combination of AVMAPKI and FAKZYNJA against standard chemotherapy, further validating its clinical benefits to ensure continued FDA approval.

About VSTM
Verastem, Inc. is a late-stage development biopharmaceutical company, which focuses on the development and commercialization of new medicines to improve the lives of patients diagnosed with ras sarcoma (RAS)/ mitogen-activated pathway kinase (MAPK) pathway-driven cancers. Its product candidates include avutometinib and defactinib. Avutometinib is an oral RAF/MEK clamp that inhibits MEK1/2 kinase activities and induces inactive complexes of MEK with A-Raf proto-oncogene, potentially serine/threonine kinase (ARAF), B-Raf proto-oncogene serine/threonine kinase (BRAF) and C-raf proto-oncogene serine/threonine kinase, creating antitumor response through maximal RAS/MAPK pathway inhibition. Defactinib is an oral, selective inhibitor of FAK and proline-rich tyrosine kinase (PYK2), the two members of the focal adhesion kinase family of non-receptor protein tyrosine kinases. FAK and PYK2 integrate signals from integrin and growth factor receptors to regulate cell proliferation.
