[{"type":"text","content":"\nAvutometinib + Sotorasib Combination Demonstrated Preliminary Efficacy with Confirmed Responses in both KRAS G12C Inhibitor Resistant and Naïve Patients\n\n\nNo New Safety Signals Observed in Combination; Most Treatment-Related Adverse Events Mild to Moderate\n\n\nEnrollment of Patients Naïve to or Previously Treated with a KRAS G12C Inhibitor Ongoing in Expansion Phase\n\n\n BOSTON--(BUSINESS WIRE)--\nVerastem Oncology (Nasdaq: VSTM) (the “Company”), a biopharmaceutical company committed to advancing new medicines for patients with cancer, announced today the initial safety, pharmacokinetics and recommended Phase 2 dose (RP2D) in the RAMP 203 trial evaluating the safety, tolerability and efficacy of avutometinib in combination with sotorasib in patients with KRAS G12C-mutant non-small cell lung cancer (NSCLC). The results will be presented at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics October 11-15, 2023 in Boston, Massachusetts.\n\n\n“The RAMP 203 study is investigating the potential benefits of a more complete vertical blockade of the RAS pathway with the combination of avutometinib and sotorasib in KRAS G12C-mutant locally advanced or metastatic NSCLC,” said Mark Awad, M.D., Associate Professor of Medicine at Harvard Medical School and Director of Clinical Research of the Lowe Center for Thoracic Oncology at the Dana-Farber Cancer Institute, investigator on the trial, and presenting author. “These initial findings, including the recommended Phase 2 dose and the encouraging preliminary efficacy and safety results, provide support for the combination, and I look forward to completing the expansion phase of the trial.”\n\n\nRAMP 203 (NCT05074810) is a Phase 1/2, multicenter, open label, dose evaluation/expansion study evaluating the efficacy and safety of avutometinib + sotorasib 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 been previously treated with a KRAS G12C inhibitor. The confirmed objective response rate (ORR) was 25% (3/12) across efficacy-evaluable patients and seen in both KRAS G12C inhibitor resistant (14.3%; 1/7) and naïve (40%; 2/5) patients.\n\n\nThe pharmacokinetic profile of avutometinib in combination with sotorasib was similar to results in monotherapy studies.
