Outcome Measures

Primary Outcomes (1)

  • Occurrence of treatment related adverse events as assessed by CTCAE v5.0

    Defined as \>= Grade 3 signs/symptoms, laboratory toxicities, and clinical events) that are possibly, likely, or definitely related to study treatment

    Baseline to 1 year post infusion

Secondary Outcomes (5)

  • The pharmacokinetic analysis of TABP EIC

    D0, D1, D3, D7, D8, D10, D14, D15, D17, D28±1, D60±2, D120±2, D180±7, D270±7, and D365±7 post infusion

  • The pharmacodynamics analysis of TABP EIC

    Baseline to infusion date, D28±1, D60±2, D120±2, D180±7, D270±7, 和 D365±7

  • The proportion of patients with a decrease in PSA levels from baseline.

    Baseline to D28±1, D60±2, D120±2, D180±7, D270±7, and D365±7 post infusion

  • Progression-free survival (PFS) after TABPEIC infusion

    Baseline to 1 year post infusion

  • Time to clinical progression

    Baseline to D28±1, D60±2, D120±2, D180±7, D270±7, and D365±7 post infusion

  • Patients voluntarily participated and signed the informed consent, and followed the trial treatment plan and visit plan.

You may not qualify if:

  • Subjects who meet one of the following conditions will not be enrolled in the trial:
