Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Isatuximab Subcutaneous (SC)
Isatuximab dose will be administered SC weekly for 4 weeks during Cycle 1 (Days 1, 8, 15, and 22) and Day 1 and 15 of subsequent cycles. Each cycle will be 28 days in duration. Pomalidomide dose will be taken orally on Day 1 to Day 21 of each cycle at the time that is the most convenient for the participants prior to or after isatuximab administration, preferably at the same time every day. Dexamethasone will be taken orally on Day 1, 8, 15 and 22 (to be repeated every 28 days). Participants may receive other treatments as background treatment and/or rescue medication.
