Intervention:

Intervention type: Biological
Intervention name: GC012F injection
Description: GC012F injection is an autologous dual CAR-T targeted BCMA and CD19. A single infusion of CAR-T cells will be administered intravenously
Arm group label: GC012F treatment

Summary: This is a single-arm, single-center, open-label clinical study to evaluate the safety and efficacy of CAR-T in patients with NDMM.

Detailed description: 9-18 evaluable subjects are planned to be enrolled in this study. Apheresis will be carried out in subjects who meet eligible criteria, and total 2 cycles of induction therapy (three-drug combination regimen based on bortezomib with details determined by the investigator according to the patient's condition) will be selectively given to subjects before or after apheresis. Next, subjects will receive a single infusion of CAR-T, and the efficacy assessments will be performed at 1st month, 3rd months, and every 3 months within 2 years until the end of the trial (MRD testing is required for each efficacy assessment) 1.Efficacy assessments performed at the 1st month after infusion: 1.
