Autogene Cevumeran Trial Terminated in Resected Colorectal Cancer

BioNTech terminated its phase 2 BNT122-01 trial of autogene cevumeran in colorectal cancer due to a DSMB recommendation, citing an imbalance in overall survival and unlikely efficacy. The trial tested the mRNA immunotherapy as a monotherapy. No new safety concerns were identified. The decision does not impact other trials, including a phase 2 study in pancreatic cancer.
