What was measured

TTNT is defined as the length of time between the date of KITE-585 infusion to the date of initiation of the next therapy or death due to any cause, whichever is earlier.

Analysis population: Participants in the Safety Analysis Set were to be analyzed. Estimates of the proportion of participants who have not required additional treatment for progressive multiple myeloma at selected time points were to be provided. As per changes in planned analysis, this outcome measure could not be analyzed at the data cutoff date due to a lack of events. Kite/Gilead did not collect data to analyze TTNT after the data cutoff date.

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.
