Summary

This is a multicenter, open-label, non-randomized, single-arm clinical trial. Patients with relapsed/refractory multiple myeloma accompanied by extramedullary infiltration will receive BCMA - GPRC5D CAR-T cell therapy.

The primary objective is to prospectively evaluate the safety of dual-targeting BCMA and GPRC5D CAR - T cell therapy for extramedullary infiltration in relapsed/refractory multiple myeloma. The primary endpoints are to assess the type and incidence of dose-limiting toxicity (DLT) within one month after the reinfusion of BCMA-GPRC5D CAR-T cells in patients, as well as the incidence and severity of adverse events within one month after the reinfusion. It is expected that no more than 18 participants will be recruited.

Conditions

  • Relapsed or Refractory Multiple Myeloma (RRMM)

Interventions

DRUG

Dual-targeting BCMA-GPRC5D CAR-T cell infusion

Approximately 3-5 days prior to BCMA-GPRC5D CAR-T cell infusion, subjects are treated with FC regimen (fludarabine and cyclophosphamide) for lymphodepletion. CAR-T cell infusion are performed 48 h after completion of chemotherapy.
