Verastem Oncology Announces Intent To Discontinue RAMP 203 Clinical Study In Advanced KRAS G12C-Mutated Non-Small Cell Lung Cancer

Verastem Oncology (NASDAQ:VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers, today announced that following evaluation of interim data from the RAMP 203 clinical trial in advanced KRAS G12C-mutated non-small cell lung cancer (NSCLC) it will discontinue the trial to focus resources on clinical development of VS-7375, an oral KRAS G12D (ON/OFF) inhibitor, in advanced NSCLC and other solid tumors. There will be no further enrollment and patients currently enrolled will have the option to continue treatment per investigator discretion. This decision reflects the evolving treatment landscape for KRAS G12C inhibitors and the strategic prioritization of programs with the greatest potential impact for patients living with advanced lung cancer.

RAMP 203 is a Phase 1/2 clinical trial being conducted in collaboration with Amgen evaluating avutometinib, an oral RAF/MEK clamp, and LUMAKRAS™ (sotorasib) in a "doublet combination" and also with defactinib, an oral FAK inhibitor, as a "triplet combination" in patients naïve to or previously treated with a KRAS G12C inhibitor.
