This open-label, single-arm, multicenter Phase 1b trial evaluates the efficacy and safety of CT041 autologous CAR T-cell injection given after adjuvant chemotherapy in people with pancreatic cancer. Participants are aged 18 to 79 with histologically confirmed pancreatic ductal adenocarcinoma who consent to and can complete all study procedures. The trial is currently recruiting.
