Outcome Measures
Primary Outcome Measures
- Safety and tolerability dose limiting toxicity [21-28 days]
Safety and tolerability: dose limiting toxicity [Time Frame: 21-28 days post administration of CT0594CP ]
Secondary Outcome Measures
- Pharmacokinetics of CT0594CP CAR-T Cells (Tmax) [From first dose of study drug adminisration to end of treatment (up to 12 months)]
peak plasma Concentration time(Tmax), of after infusion CT0594CP CAR T Cells
- Pharmacokinetics of CT0594CP CAR-T Cells (Cmax) [From first dose of study drug adminisration to end of treatment (up to 12 months)]
peak plasma Concentration(Cmax), of after infusion CT0594CP CAR T Cells
- Pharmacokinetics of CT0594CP CAR-T Cells (AUC) [From first dose of study drug adminisration to end of treatment (up to 12 months)]
area under the Plasma concentration versus time curve (AUC), of after infusion CT0594CP CAR T Cells
- To evaluate the overall safety and tolerability of CT0594CP [From first dose of study drug administration to end of treatment (up to 12 months)]
Post-treatment Adverse events (TEAE) and incidence, Special Concern Adverse Events (AESI) and incidence, treatment-related adverse events
- To evaluate the initial efficacy of CT0594CP infusion in target subjects [From first dose of study drug administration to end of treatment (up to 12 months)]
Overall response rate (ORR)、 Complete response/strict complete response (CR/sCR) rate、Response rates of VGPR and above were achieved 、Duration of response (DOR)、Progression-free survival (PFS)、Overall survival (overall survival (OS)、Minimal residual disease (MRD) negative rate as measured by International Myeloma Working Group (IMWG) criteria after CT0594CP infusion
