Clinical Study of Safety and Efficacy of Universal PSMA CAR- T in Refractory CRPC

This is a single-arm, single-center, open-label clinical trial designed to evaluate the clinical safety and tolerability of different doses of Prostate-Specific Membrane Antigen (PSMA)-Universal Chimeric Antigen Receptor (UCAR) T-lymphocytes (PSMA-UCAR T) for the treatment of patients with refractory castration-resistant prostate cancer (CRPC).

This is a single-arm, single-center, open-label clinical trial, which aims to evaluate safety and clinical efficacy of different doses of PSMA-UCAR T (BRL-302) in treating patients with refractory CRPC. Three patients will be firstly enrolled at a dose level (DL) of 5.0 × 10\^6cells/kg in the DL1 group. Based on preliminary safety data, efficacy information, and PK/PD parameters obtained at DL1 cohort, the investigator may enroll another three patients in a decreased dose level group of DL-2: 3 × 10\^6 cells/kg or DL-1:1 × 10\^6 cells/ kg, after thorough discussions between the investigators.
