Arms and Interventions

Arm

Intervention/treatment

Experimental: Carfilzomib + Lenalidomide + Dexamethasone; Treatment during Cycles 1 through 12 consisted of carfilzomib (15, 20, or 20/27 mg/m²) on Days 1, 2, 8, 9, 15, and 16; lenalidomide (10, 15, 20, or 25 mg) on Days 1 to 21; and low-dose dexamethasone (40 mg) given 30 minutes to 4 hours before the carfilzomib dose on Days 1, 8, and 15, as well as on Day 22. For Cycles 13 and higher, carfilzomib could be omitted on Days 8 and 9 at the investigator's discretion.

Drug: Carfilzomib; Carfilzomib for Injection was administered intravenously over 10 minutes on Days 1, 2, 8, 9, 15, and 16 of a 28-day cycle for the first 12 cycles. Each dose of Carfilzomib for Injection was normalized to body surface area.; Other Name: Kyprolis®; Drug: Lenalidomide; Lenalidomide was administered orally on Days 1 to 21 of each 28-day cycle.; Other Name: REVLIMID®; Drug: Dexamethasone; Dexamethasone 40 mg orally or intravenous equivalent was administered 30 minutes to 4 hours before carfilzomib on Days 1, 8, and 15, as well as on Day 22 of each 28-day cycle.

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Adverse Events (AEs) [ Time Frame: From the first dose of study drug until 30 days after the last dose; 1 to 52 months, with an average of 12 months. ]

   Treatment-related are those AEs with possible or probable relationship to carfilzomib, lenalidomide or dexamethasone as assessed by the Investigator. The severity of each adverse event was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 3.0, per the following: Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-threatening and Grade 5 = Death.

   Serious adverse events were defined as AEs meeting one of the following: death, life-threatening, required or prolonged in-patient hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect in the offspring of an exposed participant, important medical events that may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed above, or pregnancy or suspected pregnancy.

2. Number of Participants With Dose-limiting Toxicities [ Time Frame: Cycle 1, 28 days ]

   Dose-limiting toxicity was defined as any of the following events assessed as related to carfilzomib, lenalidomide, or dexamethasone: Nonhematologic

   • ≥ Grade 2 neuropathy with pain
   • ≥ Grade 3 nonhematologic toxicity (excluding nausea, vomiting, diarrhea, hyperglycemia due to dexamethasone, and rash due to lenalidomide)
   • ≥ Grade 3 nausea, vomiting, or diarrhea uncontrolled by maximal supportive therapy
   • ≥ Grade 4 fatigue persisting > 7 days
   • Treatment delay for toxicity > 21 days

   Hematologic

   • Grade 4 neutropenia (absolute neutrophil count [ANC] < 500/mm³) > 7 days
   • Febrile neutropenia (ANC < 1,000/mm³ with fever ≥ 38.3ºC)
   • Grade 4 thrombocytopenia (platelets < 25,000/mm³) for > 7 days despite holding treatment, or Grade 3 or 4 thrombocytopenia associated with bleeding
   • Treatment delay for toxicity > 21 days.

   The maximum-tolerated dose was defined as the dose level below which a drug-related DLT was observed in ≥ 33% of participants in a cohort.
