Verastem Oncology announced a clinical collaboration agreement with Amgen to evaluate the combination of VS-6766, Verastem Oncology’s investigational dual RAF/MEK inhibitor, with Amgen’s KRAS G12C inhibitor LUMAKRASTM (sotorasib) in KRAS G12C-mutant non-small cell lung cancer (NSCLC). The Phase 1/2 trial will evaluate the safety, tolerability and efficacy of VS-6766 in combination with LUMAKRASTM in patients with KRAS G12C-mutant NSCLC who have not been previously treated with a KRAS G12C inhibitor as well as in patients who have progressed on a KRAS G12C inhibitor. The study will therefore investigate the potential benefits of a more complete vertical blockade of the RAS pathway with the combination of VS-6766 (RAF/MEK blockade) with LUMAKRASTM (G12C inhibition) in KRAS G12C-mutant locally advanced or metastatic NSCLC. Verastem Oncology expects to initiate the clinical trial with VS-6766 and LUMAKRASTM by the end of 2021.
