Brief Summary:
This is a single arm, open-label, multi-center prospective study to determine the safety and efficacy of GC012F CAR-T cells in patients diagnosed with BCMA+ refractory/relapsed multiple myeloma (r/r MM).

Condition or disease Intervention/treatment Phase
Multiple Myeloma Biological: GC012F injection Early Phase 1

Detailed Description:
The main aim of the study is to determine the safety and efficacy of GC012F in r/r MM. GC012F is an autologous dual chimeric antigen receptor T-cell (CAR-T) therapy that targets B-cell maturation antigen (BCMA) and CD19. This study comprises of a Screening Phase (less than or equal to [<=] 28 days prior to apheresis) followed by Apheresis (will occur upon enrollment); Treatment Phase including a conditioning regimen followed by infusion of GC012F and post-infusion assessments from Day 1 to Day 84; and a Post-treatment Phase (Day 85 and up to end of the study). Efficacy will be explored to assessed and safety will be closely monitored during the study.

Arm Intervention/treatment
Experimental: GC012F treatment
BCMA+ R/R multiple myeloma patients be treated with a single dose of GC012F cells. Total dose of (1-5)*10E5/kg cells will be administered at Day 0.
Biological: GC012F injection
GC012F injection is a autologous dual CAR-T targeted BCMA and CD19. A single infusion of CART cells will be administered intravenously.
