Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Lenalidomide and Dexamethasone; Lenalidomide 25mg by mouth (PO) once daily (QD) on Days 1-21 of each 28 day cycle; When creatinine (CrCl) clearance <60 mL/min, the initial dose was 10mg and the dose could be increased to 15mg after 2 cycles if the investigator judged therapeutic effect was insufficient and tolerability was acceptable. Dexamethasone 40 mg by PO once QD on days 1-4, 9-12 and 17-20 of each 28 day cycle for the first 4 cycles and Days 1-4 for the remaining cycles beginning at Cycle 5.

Drug: Lenalidomide; Lenalidomide 25mg PO for (days 1 - 21) of a 28-day cycle; Other Names: CC-5013; Revlimid; Drug: Dexamethasone; Dexamethasone 40 mg by mouth (PO) daily (QD) on days 1-4, 9-12 and 17-20 of each 28 day cycle; Other Names: Decadron

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants Experiencing Treatment-Emergent Adverse Events (TEAE)	A TEAE was defined as any AE that started on or after the first dose of study drug, and within End of Study (EOS) (28 days after the last dose of study drug received). A serious AE (SAE) = any AE which results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability; is a congenital anomaly/birth defect; or constitutes an important medical event. The intensity of AEs were graded 1 to 5 according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0. For all other AEs not described in the CTCAE criteria, the intensity was assessed by the investigator as mild grade (Grade 1), moderate (grade 2), severe (grade 3), life-threatening (grade 4) or death (grade 5)	Day 1 of study drug through 28 days after the last dose of study drug; maximum treatment duration was 60.3 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Myeloma Response Rate	Overall myeloma response rate was determined by the investigator using the Myeloma Response Determination Criteria adapted from Bladé criteria. A responder is any patient who showed at least a partial response. Overall myeloma response rate is defined as the percentage of participants who achieved a Complete Response (CR), plus a Remission Response (RR), plus a Partial Response (PR). A CR is the disappearance of monoclonal paraprotein and maintained for ≥ 6 weeks. RR is a 75-99% reduction in the level of the serum monoclonal paraprotein compared to baseline; 90-99% reduction in 24-hr urinary light chain excretion. PR is a 50-74% reduction in the level of monoclonal paraprotein compared to baseline; 50-89% reduction in 24-hr urinary light chain excretion.	From the time of the first dose of study drug to study completion; median duration on study was 42.1 weeks
Kaplan-Meier Estimates of Duration of Response (DoR)	Duration of response was defined as the time from the first observation of a response (CR, RR or PR) to the first documented disease progression or relapse. For participants who did not progress during the study, duration of response was censored at the last adequate response assessment showing evidence of no disease progression. Disease progression is defined as an increase in M-protein serum monoclonal paraprotein and/or urine paraprotein or evidence of bone marrow plasmacytosis and plasma cells, an appearance of new or existing soft tissue plasmacytomas, an appearance of new or existing lytic bone lesions and/or hypercalcemia >11.5mg/dL	From the time of the first dose of study drug to study completion; the median duration on study was 42.1 weeks
