What was measured

BM aspirate was collected for fluorescent in situ hybridization for analysis of del\[17p\], t\[4;14\], t\[14;16\]) and 1q21+. ORR was also evaluated based on IRC assessment by disease characteristics. ORR for participants with at least 1 chromosomal abnormality i.e. \[del(17p)\] or \[1q21+ and t(4;14) or t(14;16)\] is presented. Percentages are rounded off to the tenth decimal place.

Analysis population: The ITT population included all randomized population. Only participants with at least 1 chromosomal abnormality are included in the analysis.

Groups in this outcome

Isa-IV + Pd

Participants received isatuximab 10 mg/kg IV infusion QW (i.e. on Days 1, 8, 15 and 22) in Cycle 1 (28 days) and then 10 mg/kg Q2W (i.e. on Days 1 and 15) of each subsequent 28-day cycle along with pomalidomide 4 mg orally on Days 1 to 21 of each 28-day cycle and dexamethasone 40 mg (or 20 mg for participant \>=75 years) orally on Days 1, 8, 15, and 22 of each cycle until disease progression, unacceptable AEs, participant request to discontinue treatment, or any other reason, whichever came first.

Isa-SC + Pd

Participants received isatuximab 1400 mg SC injection administered via an OBDS which is an investigational device injector QW (i.e on Days 1, 8, 15 and 22) in Cycle 1 (28 days) and then 1400 mg Q2W (i.e. on Days 1 and 15) of each subsequent 28-day cycle along with pomalidomide 4 mg orally on Days 1 to 21 of each 28-day cycle and dexamethasone 40 mg (or 20 mg for participant \>=75 years) orally on Days 1, 8, 15, and 22 of each cycle until disease progression, unacceptable AEs, participant request to discontinue treatment, or any other reason, whichever came first.
