What was measured

Infusion reactions were graded using National Cancer Institute-Common Terminology Criteria for AE (NCI-CTCAE) version (v)5.0 criteria: Grade 1: mild transient reaction; infusion interruption not indicated; intervention not indicated. Grade 2: moderate reaction; therapy or infusion interruption indicated but responds promptly to symptomatic treatment; prophylactic medications indicated for \<=24 hours. Grade 3/4: severe or life-threatening reaction (Grade 3: prolonged \[not rapidly responsive to symptomatic medication and/or brief interruption of infusion\]; recurrence of symptoms following initial improvement; hospitalization indicated for clinical sequelae. Grade 4: life-threatening consequences; urgent intervention indicated). Percentage of participants who observed AE of infusion reactions were collected through the electronic case report form (eCRF) as assessed by investigators. Percentages are rounded off to the tenth decimal place.

Analysis population: The safety population included ITT participants who received at least 1 dose or a part of a dose of the study medication.

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.

    group Description
    A hierarchical test procedure was used to control the Type I error. Testing was performed sequentially for first 4 secondary endpoints in the order they are presented only if both co-primary endpoints achieved non-inferiority and continued when the previous endpoint was statistically significant at 1-sided significance level of 0.025.
