Hope on the Horizon: A Revolution in KRAS Inhibition Is Creating a New Treatment Paradigm for Patients with Pancreatic Cancer

Abstract KRAS is the most frequently altered oncogene in pancreatic ductal adenocarcinoma, in which the aberrantly activated RAS signaling pathway plays pleiotropic roles in tumor initiation and maintenance. Nearly four decades after the discovery of the RAS oncoprotein, a multitude of pharmacologic inhibitors are now available that directly target mutant KRAS. This In Focus commentary, published simultaneously with the 2024 AACR Special Conference on Pancreatic Cancer, summarizes the current state of this rapidly changing field, including preclinical data and emerging clinical trends with respect to therapeutic efficacy, mechanisms of resistance, and potential combinations to maximize clinical benefit from this promising class of therapies.
