Revolution Medicines, Inc. (NASDAQ:RVMD), a clinical-stage oncology company developing targeted therapies for RAS-addicted cancers, today announced promising anti-tumor and safety data for RMC-6236, its RASMULTI(ON) Inhibitor, in patients with previously treated non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC) across several dose levels and KRASG12X genotypes, including common KRAS-mutant genotypes G12D and G12V. These initial results were presented during a Proffered Paper session at the European Society for Medical Oncology (ESMO) Congress in Madrid, October 20-24, 2023
RMC-6236 demonstrated preliminary evidence of clinical activity and an acceptable safety profile that was generally well tolerated across the dose levels analyzed. Clinical activity was evaluated in patients who had received the first dose of RMC-6236 at least eight weeks prior to the data extraction date (n=86). Among the 40 efficacy evaluable NSCLC patients, the objective response rate was 38 percent, with one patient achieving a complete response (CR) as a best response and 14 patients achieving a partial response (PR) (including three unconfirmed PRs). The disease control rate (DCR) in this NSCLC population was 85 percent. Among the 46 efficacy evaluable PDAC patients, the objective response rate was 20 percent, with nine patients achieving a PR (including four unconfirmed PRs) as a best response. The DCR in this PDAC population was 87 percent. Confirmed objective responses included tumors harboring KRAS mutations G12D, G12V or G12R, and disease control was observed across all KRAS mutations, including G12A and G12S.
