Colorectal Cancer Clinical Trial
Official title:
A Safety and Efficacy Clinical Study of CEA-targeted CAR-T Therapy for CEA-positive Advanced Malignant Solid Tumors
This trial is an open-label, single-arm clinical study. The main purpose is to verify the safety and efficacy of CAR-T cell preparations in the treatment of CEA-positive advanced malignant tumors, and to obtain the recommended dose and infusion scheme of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignant tumors.
Carcinoembryonic antigen (CEA) is a classic tumor marker, which is positively expressed in a variety of digestive tract tumors. In normal tissue cells, only a small amount of CEA is expressed in the cell membrane of digestive tract cells. In the early clinical trials of CAR-T targeting CEA carried out by the technical partner, it was found that CAR-T cell preparations have a certain killing effect on CEA-positive tumor cells. At the same time, no serious CAR-T-related adverse events were found through dose-escalating infusion. In this study, through the optimization of the CAR structure and the improvement of the culture method, the killing ability and survival ability of the CAR-T cell preparation on tumor cells in vitro and in vivo were improved to further verify the safety and efficacy. ;
