Verastem Presents Avutometinib and Defactinib Combination Program Updates at the 5th Annual RAS-Targeted Drug Development Summit
Preclinical and Clinical Presentations Include Update on FRAME Study Low-Grade Serous Ovarian Cancer Efficacy Data
The clinical presentation includes updated FRAME study efficacy data showing an overall response rate (ORR) of 42% (11 of 26) in evaluable patients with low grade serous ovarian cancer (LGSOC) (n=26). Among patients with KRAS mutant LGSOC (n=12), the ORR was 58% (7 of 12), compared to patients with KRAS wild-type LGSOC (n=12), the ORR was 33% (4 of 12). Across all LGSOC patients, the median duration of response was 26.9 months (95% CI: 8.5-47.3) while median progression free survival (PFS) was 20.0 months (95% CI: 11.1-31.2). As of the
“We are encouraged that the high rate and long duration of objective responses in the recurrent LGSOC cohort of the FRAME study continue to provide foundational proof-of-concept supporting Breakthrough Therapy Designation for the combination of avutometinib and defactinib,” said
The FRAME study, led by Professor

About the Avutometinib and Defactinib Combination
Avutometinib is a RAF/MEK clamp that induces inactive complexes of MEK with ARAF, BRAF and CRAF potentially creating a more complete and durable anti-tumor response through maximal RAS pathway inhibition. In contrast to currently available MEK inhibitors, avutometinib blocks both MEK kinase activity and the ability of RAF to phosphorylate MEK. This unique mechanism allows avutometinib to block MEK signaling without the compensatory activation of MEK that appears to limit the efficacy of other inhibitors. The
Verastem Oncology is currently conducting clinical trials with its RAF/MEK clamp avutometinib in RAS pathway-driven tumors as part of its (Raf And Mek Program). RAMP 301 is a planned Phase 3 confirmatory trial evaluating the combination of avutometinib and defactinib versus standard chemotherapy or hormonal therapy for the treatment of recurrent LGSOC. RAMP 201 is a Phase 2 registration-directed trial of avutometinib in combination with defactinib in patients with recurrent LGSOC and has completed enrollment in the dose optimization and expansion phases and is enrolling for low-dose evaluation. Verastem Oncology has established clinical collaborations with Amgen and Mirati to evaluate LUMAKRAS™ (sotorasib) and KRAZATI™ (adagrasib) in combination with avutometinib in KRAS G12C mutant NSCLC as part of the RAMP 203 and RAMP 204 trials, respectively. Supported by the “Therapeutic Accelerator Award” Verastem Oncology received from PanCAN, the Company is conducting RAMP 205, a Phase 1b/2 clinical trial evaluating avutometinib and defactinib with gemcitabine/nab-paclitaxel in patients with front-line metastatic pancreatic cancer.
