What was measured
Ctrough at steady state was the observed plasma concentration collected on pre-dose at Cycle 6 Day 1 (equivalent to prior to Cycle 6 Day 1) of isatuximab administration dose.
Analysis population: Per Protocol-Pharmacokinetic (PP-PK) population: all randomized participants who met following: at least 11 Isa dose from Cycle 1 Day 1 to Cycle 5 Day 15 (1 dose omission permitted at Cycle 1 only); Isa pre-dose plasma concentration results from PK samples on Cycle 6 Day 1 collected within PP defined time window with adequate documentation of dosing and sampling dates and times.
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.
