What was measured

Complete response (CR) and Partial Response (PR) were based on the European Group for Blood and Bone Marrow Transplant (EBMT) Criteria. Very Good Partial response was derived from the International Myeloma Working Group (IMWG) criteria. Participants who had a reduction in M-protein or plasmacytoma but did not meet the EBMT criteria for PR were classified as minimal response (MR). Hematologic, radiologic and/or clinical assessments were done every cycle starting with cycle 2. Each cycle is 4 weeks in length (Day 1, Day 8, Day 15, Day 22). Cycle 2 began on study Day 29. CR=negative immunofixation 6 weeks, \<5% plasma cells, no increase in size or number of lytic lesions, complete disappearance of extramedullary plasmacytoma. PR=≥50%reduction in M-protein for 6 weeks, ≥90% reduction of urinary light chain excretion or \< 200 mg/24hours for 6 weeks, ≥50% reduction in size of extramedullary plasmacytoma present at baseline, no increase in size or number of lytic lesions.

Analysis population: All participants who received at least one dose of study medication were summarized (Treated Participants).

Groups in this outcome

Elotuzumab 10 mg/kg

Elotuzumab was administered IV at a dose of 10 mg/kg weekly (Days 1, 8, 15 and 22 of 4-week cycle) for the first 2 cycles and bi-weekly (every 2 weeks) (Day 1 and Day 15) thereafter until disease progression or unacceptable toxicity became apparent. Lenalidomide 25 mg was administered PO once daily for the first 3 weeks of each 4-week cycle. The dose of lenalidomide was administered at least 2-4 hours after completion of elotuzumab infusion. On weeks without elotuzumab administration, dexamethasone was administered PO as a single dose of 40 mg. On weeks of elotuzumab infusion, the weekly dose of dexamethasone was administered as a split dose of: 28 mg PO (between 3 to 24 hours prior to the start of the elotuzumab infusion) and 8 mg IV (At least 45 min prior to the start of the elotuzumab infusion).

Elotuzumab 20 mg/kg

Elotuzumab was administered IV at a dose of 20 mg/kg weekly (Days 1, 8, 15 and 22 of 4-week cycle) for the first 2 cycles and bi-weekly (every 2 weeks) (Day 1 and Day 15) thereafter until disease progression or unacceptable toxicity became apparent. Lenalidomide 25 mg was administered PO once daily for the first 3 weeks of each 4-week cycle. The dose of lenalidomide was administered at least 2-4 hours after completion of elotuzumab infusion. On weeks without elotuzumab administration, dexamethasone was administered PO as a single dose of 40 mg. On weeks of elotuzumab infusion, the weekly dose of dexamethasone was administered as a split dose of: 28 mg PO (between 3 to 24 hours prior to the start of the elotuzumab infusion) and 8 mg IV (At least 45 min prior to the start of the elotuzumab infusion).
