Detailed Description
This study will include two parts, dose escalation phase (accelerated titration and 3+3 design) followed by a dose expansion phase (Cohort 1: Malignant mesothelioma; Cohort 2: Advanced malignant tumors of the digestive system; Cohort 3: Other advanced malignant solid tumors.).
All eligible participants will receive a conditioning chemotherapy regimen of fludarabine and cyclophosphamide followed by UCLM802 cell injection.
The dose escalation phase will determine the maximum tolerated dose (MTD) of UCLM802 cell injection. Additional patients will be enrolled in the dose expansion phase to further characterize the safety profile and evaluate the efficacy of UCLM802 cell injection, and establish recommended phase 2 dose (RP2D).
