Brief summary
An open-label, single-arm, multicenter, Phase Ib clinical trial to evaluate the efficacy and safety of CT041 Autologous CAR T Cell Injection after adjuvant chemotherapy in subjects with pancreatic cancer.
Detailed description
This study is an open, multicenter, Phase Ib clinical trial evaluating chimeric antigen receptor-modified autologous T cells targeting Claudin18.2 (CLDN18.2) (CT041 autologous CAR T) in subjects with CLDN18.2 expression-positive pancreatic cancer who has undergone adjuvant chemotherapy. The aim of this study is to evaluate the efficacy, safety of CT041 treatment.
Interventions
Treatment with anti-claudin18.2 chimeric antigen receptor T-cell infusion. Up to 3 times CT041 autologous CAR T-cell injection infusion
