What was measured

Ctrough was the plasma concentration observed just before treatment administration during repeated dosing.

Analysis population: Analysis was performed on PK population. Here, "Number analyzed" = participants with available data for each specified category and "0" in the number analyzed field signifies that no participants were available for analysis at specified timepoint.

Groups in this outcome

Phase 1, Cohort 1: Isatuximab 10 mg/kg

Participants received Isatuximab 10 mg/kg IV infusion QW for 4 weeks (i.e., on Day 1, Day 8, Day 15 and Day 22 of Cycle 1), and then Q2W (i.e., on Day 1 and 15) for subsequent treatment cycles (each cycle of 28 days) until unacceptable AEs, disease progression, or any other reason for discontinuation whichever occurs first (maximum duration of exposure: 112 weeks).

Phase 1, Cohort 2: Isatuximab 20 mg/kg

Participants received Isatuximab 20 mg/kg IV infusion, QW for 4 weeks (i.e., on Day 1, Day 8, Day 15 and Day 22 of Cycle 1), and then Q2W (i.e., on Day 1 and 15) for subsequent treatment cycles (each cycle of 28 days) until unacceptable AEs, disease progression, or any other reason for discontinuation whichever occurs first (maximum duration of exposure: 137 weeks).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
