Chimeric Antigen Receptor Macrophages Targeting c-MET for Advanced Stage of Pancreatic Cancer Patients

Chimeric antigen receptor macrophages (CAR-M) represent one of the most promising cellular immunotherapies for solid tumors. Patients with advanced-stage pancreatic cancer face an extremely dismal prognosis, particularly following the failure of chemotherapy. This trial investigates the role of CAR-M cellular therapy in advanced pancreatic cancer patients who have progressed after prior chemotherapy. C-MET is a target highly expressed in the majority of pancreatic cancer tissues. In this study, a chimeric antigen receptor targeting c-MET is designed and cloned into an adenoviral vector. Peripheral blood mononuclear cells are collected from participants, and CD14-positive monocytes are isolated. These monocytes are then induced and expanded using Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF), and subsequently transduced with the c-MET-specific CAR-adenoviral vector to generate CAR-M-c-MET. The final cell product is cryopreserved and later administered via intraperitoneal infusion. Each patient receives a single dose of cell infusion. Following infusion, the safety, efficacy, and pharmacokinetics of CAR-M-c-MET therapy are comprehensively evaluated.
