Time frame
Disease response was assessed at the end of each cycle and 30 days after the last treatment; maximum treatment duration was 32 weeks.

What was measured

Participants were evaluated for disease response and progression by the investigator according to the International Myeloma Working Group-Uniform Response Criteria (IMWG-URC). Disease response and progression assessments included serum protein electrophoresis (SPEP), urine protein electrophoresis (UPEP), serum immunofixation, serum free light chain (SFLC), bone marrow sample (including fluorescent in situ hybridization \[FISH\]), plasmacytoma evaluation, and skeletal survey. Overall response rate is defined as the percentage of participants with a best response of stringent complete response, complete response, very good partial response (VGPR), or partial response.

Carfilzomib 36 mg/m²

Participants received 36 mg/m² carfilzomib IV infusion on days 1, 2, 8, 9,15, and 16 of each 28 day cycle (on days 1 and 2 of cycle 1, all participants received carfilzomib at 20 mg/m²), cyclophosphamide administered orally at 300 mg/m² on days 1, 8, and 15, and 40 mg dexamethasone on days 1, 8, 15, and 22, for up to eight 28 day cycles, or until progressive disease (PD), unacceptable toxicity, withdrawal of consent, or death.

Carfilzomib 45 mg/m²

Participants received 45 mg/m² carfilzomib IV infusion on days 1, 2, 8, 9,15, and 16 of each 28 day cycle (on days 1 and 2 of cycle 1, all participants received carfilzomib at 20 mg/m²), cyclophosphamide administered orally at 300 mg/m² on days 1, 8, and 15, and 40 mg dexamethasone on days 1, 8, 15, and 22, for up to eight 28 day cycles, or until progressive disease (PD), unacceptable toxicity, withdrawal of consent, or death.

Carfilzomib 56 mg/m²

Participants received 56 mg/m² carfilzomib IV infusion on days 1, 2, 8, 9,15, and 16 of each 28 day cycle (on days 1 and 2 of cycle 1, all participants received carfilzomib at 20 mg/m²), cyclophosphamide administered orally at 300 mg/m² on days 1, 8, and 15, and 40 mg dexamethasone on days 1, 8, 15, and 22, for up to eight 28 day cycles, or until progressive disease (PD), unacceptable toxicity, withdrawal of consent, or death.
