What was measured
VGPR or better response rate was defined as the percentage of participants who achieved VGPR or complete response (CR) (including stringent complete response \[sCR\]) according to the IMWG criteria during or after the study treatment. VGPR: Serum and urine component detectable by immunofixation but not on electrophoresis, or \>= 90% reduction in serum M-protein plus urine M-protein level less than (\<) 100 mg/24 hour; CR: negative immunofixation on the serum and urine, disappearance of any soft tissue plasmacytomas and \<5% PCs in bone marrow; sCR: CR in addition to having a normal free light chain (FLC) ratio and an absence of clonal cells in bone marrow by immunohistochemistry, immunofluorescence, 2-4 color flow cytometry.
Analysis population: mITT analysis Set included all participants who received a JNJ-68284528 infusion at the targeted RP2D dose level. Here, N (number of participants analyzed) signifies participants who were evaluable for this outcome measure.
Groups in this outcome
Phase 1b (US Population)
Participants received a conditioning regimen of cyclophosphamide 300 milligrams per meter square (mg/m\^2) intravenous (IV) infusion and fludarabine 30 mg/m\^2 as IV infusion daily for 3 days from Day -5 to Day -3. On Day 1, participants received target dose of JNJ-68284528 0.75\*10\^6 chimeric antigen receptor T (CAR-T) cells per kilogram (cells/kg) (range: 0.5-1.0\*10\^6 CAR-positive viable cells/kg) as IV infusion.
Phase 2 (US Population)
Participants received a conditioning regimen of cyclophosphamide 300 mg/m\^2 IV infusion and fludarabine 30 mg/m\^2 IV infusion daily for 3 days from Day -5 to Day -3. On Day 1, participants received recommended phase 2 dose (RP2D) dose of JNJ-68284528 0.75\*10\^6 CAR positive viable T cells/kg as IV infusion.
Phase 2 (Japan Population)
Participants received a conditioning regimen of cyclophosphamide 300 mg/m\^2 IV infusion and fludarabine 30 mg/m\^2 IV infusion daily for 3 days from Day -5 to Day -3. On Day 1, participants received RP2D dose of JNJ-68284528 0.75\*10\^6 CAR positive viable T cells/kg as IV infusion.
