What was measured

ORR: Percentage of participants who achieved a stringent CR (sCR), complete response (CR), partial response (PR), or very good PR (VGPR), as determined by IMWG Consensus Panel 1 Criteria. sCR: CR+normal free light chain (FLC) ratio, no clonal cells in BM by immunohistochemistry or immunofluorescence; CR: negative immunofixation (IFX) on serum and urine, no soft tissue plasmacytomas (STP), \<5% plasma cells in bone marrow (BM); PR: ≥50% decrease of serum M-protein + 24hr urinary M-protein decrease by ≥90% or \<200 mg/24hr. If unmeasurable serum and urine M-protein; and serum-free light assay; requires ≥ 50% decrease in the difference between involved and uninvolved FLC levels / ≥ 50% reduction in plasma cells (PC), provided baseline BM PC percentage was ≥ 30%, respectively. If present at baseline, ≥ 50% reduction in the size of STP is also required; VGPR: serum and urine M-protein detected by IFX but not electrophoresis, \>90% in serum M-protein+urine, M-protein level \<100 mg/24hr.

Analysis population: The Safety Analysis Set included all participants treated with any dose of KITE-585.

Groups in this outcome

Dose Escalation: 3 x 10^7 KITE-585

Participants with RRMM, received conditioning chemotherapy consisting of cyclophosphamide 300 mg/m\^2/day and fludarabine 30 mg/m\^2/day IV infusion for 3 days followed by a single infusion of KITE-585 at a dose of 3 x 10\^7 autologous anti-BCMA CAR T cells on Day 0.

Dose Escalation: 1 x 10^8 KITE-585

Participants with RRMM, received conditioning chemotherapy consisting of cyclophosphamide 300 mg/m\^2/day and fludarabine 30 mg/m\^2/day IV infusion for 3 days followed by a single infusion of KITE-585 at a dose of 1 x 10\^8 autologous anti-BCMA CAR T cells on Day 0.

Dose Escalation: 3 x 10^8 KITE-585

Participants with RRMM, received conditioning chemotherapy consisting of cyclophosphamide 300 mg/m\^2/day and fludarabine 30 mg/m\^2/day IV infusion for 3 days followed by a single infusion of KITE-585 at a dose of 3 x 10\^8 autologous anti-BCMA CAR T cells on Day 0.

Dose Escalation: 1 x 10^9 KITE-585

Participants with RRMM, received conditioning chemotherapy consisting of cyclophosphamide 300 mg/m\^2/day and fludarabine 30 mg/m\^2/day IV infusion for 3 days followed by a single infusion of KITE-585 at a dose of 1 x 10\^9 autologous anti-BCMA CAR T cells on Day 0.

Dose Expansion (Renal Impairment): 3 x 10^7 KITE-585

RRMM participants with moderate renal impairment (creatinine clearance 30 to 59 mL/min \[Grade 2 chronic kidney disease\]) received conditioning chemotherapy consisting of cyclophosphamide 300 mg/m\^2/day and fludarabine 24 mg/m\^2/day IV infusion for 3 days followed by single infusion of KITE-585 at a tolerable dose of 3 x 10\^7 autologous anti-BCMA CAR T cells on Day 0.
