Study of CEA Targeting CAR-T (PTC13) in the Treatment of CEA-Positive Advanced Malignant Solid Tumors

Is NCT06821048 recruiting? Yes, currently enrolling (May 2026). This Phase 1 trial studies Intraperitoneal infusion of FAST CEA-targeted CAR-T for colorectal cancer.

Phase 1RecruitingWeijia Fang, MDNCT06821048Data as of May 2026

Treatment: Intraperitoneal infusion of FAST CEA-targeted CAR-TThis is a phase I clinical study to evaluate the safety and tolerability of FAST targeted chimeric antigen receptor (CAR)-T cells (PTC13) in patients with carcinoembryonic antigen (CEA)-positive advanced malignant solid tumors, and to obtain the maximum tolerated dose of FAST CAR-T (PTC13) and phase II Recommended dose.
