BCMA CAR-T Versus ASCT in Transplant-eligible Patients With Multiple Myeloma (CAREMM-006)

A Prospective, Non-inferiority Study Comparing VRD±D Followed by BCMA CAR-T Cell Therapy Versus VRD±D Followed by Autologous Hematopoietic Stem Cell Transplantation in Transplant-eligible Patients With Newly-diagnosed Multiple Myeloma

This is a prospective, non-inferiority study comparing VRD±D followed by BCMA CAR-T cell therapy versus VRD±D followed by autologous hematopoietic stem cell transplantation in the treatment of newly diagnosed multiple myeloma patients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: ASCT; Patients will receive 3-4 cycles induction treatment, and high-dose melphalan conditioning, followed by autologous transplantation.Three months post-transplant, patients will undergo 2-3 cycles of consolidation therapy, followed by maintenance therapy for ≥2 years or until disease progression, death, intolerance, withdrawal for other reasons, or the study's termination/completion.	Biological: ASCT; Autologous stem cell infusion
Experimental: BCMA CAR-T; Patients will receives 3-4 cycles of induction therapy, 2-3 cycles of consolidation treatment, followed by Fc-based conditioning and CAR-T cell infusion. One month after CAR-T cell therapy, patients will begin maintenance therapy for ≥2 years or until disease progression, death, intolerance, withdrawal for other reasons, or the study's termination/completion.	Biological: anti-BCMA CAR-T; Autologous BCMA-directed CAR-T cells, infusion intravenously at a target dose of 2.0-4.0 x 10^6 anti-BCMA CAR+T cells/kg.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Persistent MRD-negative rate	achieving MRD-negative, as determined by NGS/NGF	Up to 2 year
Progression free survival (PFS)	Progression free survival is defined as the time from the date of diagnosis to the date of first documented PD, as defined in the IMWG criteria, or death due to any cause, whichever occurs first	Up to 5 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	Overall survival is measured from the date of diagnosis to the date of the participant's death.	Up to 5 year
Complete response rate (CRR)	CR or better is defined as percentage of participants who achieve a CR response or Stringent Complete Response (sCR) response accoording to the IMWG criteria	within 1 week after induction therapy, 1 month after the CAR-T cell infusion or ASCT, within 1 week after consolidation therapy
