Study Overview
Brief Summary
This study is a single-arm, single-center investigator-initiated trial (IIT) designed to evaluate the safety and preliminary efficacy of CDH17/GUCY2C CAR-T cell therapy in patients with advanced colorectal cancer, as well as to assess its pharmacodynamic (PD) and pharmacokinetic (PK) profiles.
