Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest malignancies in western countries harboring constitutively activated RAS-RAF-MEK-ERK signaling. The allosteric MEK1/2 inhibitor refametinib was evaluated as a potential therapeutic strategy for PDAC using genetically engineered mouse models. Refametinib treatment efficiently blocked ERK1/2 phosphorylation and induced apoptosis, which was responsible for the massive tumor shrinkage in vivo. Prolongation of survival was also observed and thus, refametinib seems to be a novel promising chemotherapeutic agent for PDAC.
