Brief summary
The purpose of this study is to evaluate the safety and efficacy of BiRd regimen combined with BCMA CAR T cell therapy in newly diagnosed multiple myeloma patients
Detailed description
This is a phase 3, single arm, multi-center study. The patients will receive BiRd regimen (clarithromycin,lenalidomide, dexamethasone) combined with infusion of autologous BCMA-directed CAR T-cells in newly diagnosed MM patients. The study participation will be 4 years including treatment and follow-up periods.
Interventions
* clarithromycin: 500mg, PO, twice daily, on days 1\ 21 for a 28-day cycle. * lenalidomide: 25mg, PO, on days 1\ 21 for a 28-day cycle. dexamethasone: 40mg, PO on days 1,8,15 and 22 for a 28-day cycle. BCMA CAR T cell: (2-3)×10E7/kg, intravenously infusion. * Doses should be adjusted according to renal function.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall response rate (ORR) | 4 weeks after CAR T-cells infusion (up to 14 weeks) | ORR includes stringent complete response (sCR), complete remission (CR), very good partial remission (VGPR) and partial remission (PR). Stringent complete response (sCR): complete response as defined below plus normal free light chain (FLC) and absence of clonal cells in bone marrow biopsy by immunohistochemistry (κ/λ ratio ≤4:1 or ≥1:2 for κ and λ patients, respectively, after counting ≥100 plasma cells). Complete Response (CR):negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \<5% plasma cells in bone marrow aspirates. Very good partial response (VGPR):serum and urine M-protein detectable by immunofixation but not on electrophoresis or ≥90% reduction in serum M-protein plus urine M-protein level \<100 mg per 24 h. Partial response (PR): ≥50% reduction of serum M-protein plus reduction in 24 h urine M-protein by ≥90% or to \<200 mg per 24 h. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival (OS) | 4 years | time from enrollment to the date of death from any cause |
| Event-free survival (EFS) | 4 years | time from enrollment to the date of primary refractory disease, or relapse from sCR, or CR, or death from any cause |
| Cumulative incidence of relapse(CIR) | 4 years | time from the date of achievement of a remission until the date of relapse |
| Number of adverse events | 2 years | adverse events are evaluated with CTCAE V5.0 |
