Time frame: Baseline, Day 1 of each cycle (Cycle 2 to Cycle 25), at the End of Treatment visit (any day up to 114 weeks)

What was measured

The EQ-5D-5L is a standardized measure of health status that provides a general assessment of health utility and consist in 2 sections a descriptive system comprising 5 dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) and Visual Analog Scale (VAS). Each dimension has a 5-level response: no problems, slight problems, moderate problems, severe problems, and extreme problems. Response options are measured with a 5-point Likert scale. The 5D-5L systems are converted into a single index utility score between 0 to 1, where higher score indicates a better health state and lower score indicate worse health state.

Analysis population: Analysis was performed on ITT population. Here, 'Number analyzed' signifies participants with available data for each specified category.

Groups in this outcome

Carfilzomib + Dexamethasone (Kd)

Participants received carfilzomib 20 mg/m\^2, IV infusion 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 along with dexamethasone 20 mg, PO or IV on Days 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: 114 weeks).

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).
