ORR (CR and PR)
Time Frame: At 6 months after BCMA CART and CD19 CART infusion

Complete response (CR) was defined as serum creatinine ≤ 1.2 mg/dl or ≤ 125% of baseline value, and urine protein/creatinine ratio < 0.5 or 24-hour urine protein quantification < 0.5 g, and prednisone dose reduction to ≤ 10 mg/d (or equivalent dose).
Partial response (PR) was defined as if both serum creatinine and urine protein/creatinine ratio (or 24-hour urine protein quantification) were abnormal before treatment, both items improved by > 30% after treatment, without other indicators of deterioration; if only urine protein/creatinine ratio (or 24-hour urine protein quantification) was abnormal before treatment, the improvement was > 50% after treatment.
