What was measured

AUC was defined as area under the plasma concentration-time curve extrapolated to infinity according to the equation: AUC= AUClast + Clast/λz. AUC was calculated using the non-compartmental analysis after the intravenous infusion of carfilzomib with isatuximab.

Analysis population: Analysis was performed on PK population. Data for this OM was not planned to be collected and analyzed for Kd arm. Here, 'overall number of participants analyzed' = participants with available data for this outcome measure.

Groups in this outcome

Isatuximab + Carfilzomib + Dexamethasone (IKd)

Participants received isatuximab 10 mg/kg, IV infusion on Days 1, 8, 15 and 22 in Cycle 1, and then on Days 1 and Day 15 of each 28-day treatment cycle plus carfilzomib 20 mg/m\^2, IV on Days 1, and 2 in Cycle 1, and then escalated to 56 mg/m\^2 on Days 8, 9, 15 and 16 of Cycle 1 and then on Days 1, 2, 8, 9, 15 and 16 of each subsequent 28-day treatment cycle and dexamethasone 20 mg, PO or IV on Day 1, 2, 8, 9, 15, 16, 22 and 23 of each 28-day treatment cycle until disease progression or unacceptable adverse event or participant's decision to discontinue the study treatment or any other reason, whichever comes first (maximum exposure: 111 weeks).
