主要终点：Safety Evaluation:Incidence and Severity of Adverse Events · To evaluate the incidence and severity of possible adverse events within one month after targeted PSMA CAR-T infusion, including cytokine release syndrome and on-target toxicity. · First 1 month after CAR-T cells infusion；Effectiveness Evaluation · In order to observe the efficacy of CAR-T cells after infusion, total remission rate (ORR), complete remission (CR), partial remission (PR), disease stability (SD) or progression (PD) will be used for evaluation. · 3 months after CAR-T cells infusion
次要终点：Progression-free Survival (PFS)；Overall Survival (OS)

• CAR-T cell immunotherapy · EXPERIMENTAL · The registered patients will receive CAR-T cell immunotherapy for the new specific chimeric antigen receptor of PSMA antigen by infusion.

This is an experimental study to evaluate the safety and effectiveness of PSMA-targeted CAR-T cells in the treatment of castration-resistant prostate cancer.
