Primary	Number of Participants With Serious Adverse Events (SAEs), Adverse Events (AEs) Leading to Discontinuation, Deaths	AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug. Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4= Potentially Life-threatening or disabling. Data cut-off February 2014.	First dose (Day 1) to last dose plus 60 days (assessed up to January 2017, approximately 71 months)
Primary	Number of Participants With Clinically Relevant Vital Sign Findings	Vital signs (body temperature, seated blood pressure, heart rate, and respiration rate) were recorded at screening on Days 1, 8, 15, and 22 of Cycles 1 and 2, on Days 1 and 15 of Cycle 3, and at the end of treatment. Blood pressure (Diastolic and Systolic) and heart rate were recorded after the participant sat quietly for at least 5 minutes. Clinical relevance of vital sign data was determined by the investigator.	First dose (Day 1) to last dose plus 60 days (assessed up to January 2017, approximately 71 months)
Primary	Number of Participants With Worst Toxicity Grade Hematology Laboratory Tests	National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 3.0 was used to measure toxicity scale. Lower Limits of Normal (LLN). Hemoglobin Gr 1:	First dose (Day 1) to last dose plus 60 days (assessed up to January 2017, approximately 71 months)
Primary	Number of Participants With Worst Toxicity Grade Renal and Liver Function Laboratory Tests	National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 3.0 was used to measure toxicity scale. Lower Limits of Normal (LLN). Upper Limits of Normal (ULN). Alanine transaminase (ALT); Aspartate aminotransferase (AST); Alkaline phosphatase (ALP). ALT Grade (Gr)1:>1.0 to 2.5*ULN; Gr 2: >2.5 to 5.0*ULN; Gr 3: >5.0 to 20.0*ULN; Gr 4: >20.0*ULN. AST Gr 1: >1.0 to 2.5*ULN; Gr 2: >2.5 to 5.0*ULN; Gr 3: >5.0 to 20.0*ULN; Gr 4: >20.0*ULN.

Secondary	Number of Participants With Best Overall Response - Treated Participants	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.	Cycle 2 (Study Day 29) to last dose (assessed up to January 2017, approximately 71 months)
Secondary	Geometric Mean Maximum Observed Serum Elotuzumab Concentration (Cmax) During Cycles 1, 2, and 3	The quantification of elotuzumab in human serum was performed using a validated enzyme-linked immunosorbent assay (ELISA). Cmax was measured in micrograms per milliliter (µg/mL). Samples of serum were obtained at: Cycle 1, Day 1: 0 hour (h), 30 minutes (min) 2 h post dose; Day 8: 0h, 2 h; Day 15: 0h, 30 min; Day 22: 0h, 30min, 2h. Cycle 2, Day 1, 22 0h, 2h. Cycle 3, Day 1: 0h, 30h, 2h; Day 15: 0h.	Days 1, 8, 15 and 22 of cycle 1, Days 1 and 22 of cycle 2, Days 1 and 15 of cycle 3
Secondary	Geometric Mean Minimum Observed Serum Elotuzumab Concentration (Cmin) During Cycles 1, 2, and 3	The quantification of elotuzumab in human serum was performed using a validated enzyme-linked immunosorbent assay (ELISA). Cmin was measured in micrograms per milliliter (µg/mL). Samples of serum were obtained at: Cycle 1, Day 1: 0 hour (h), 30 minutes (min) 2 h post dose; Day 8: 0h, 2 h; Day 15: 0h, 30 min; Day 22: 0h, 30min, 2h. Cycle 2, Day 1, 22 0h, 2h. Cycle 3, Day 1: 0h, 30h, 2h; Day 15: 0h.	Days 8, 15 and 22 of cycle 1, Days 1 and 22 of cycle 2, Days 1 and 15 of cycle 3
Secondary	Number of Participants Positive for Anti-Elotuzumab Anti-drug Antibodies - Treated Participants	The detection of anti-elotuzumab anti-drug antibodies (ADAs) in human serum was performed using a validated bridging electrochemiluminescence immunoassay (ECLA) on the Meso Scale Discovery (MSD) platform. Sample collection was performed prior to administration of elotuzumab at Day 1 of each cycle.	First dose (Day 1) to last dose plus 60 days (assessed up to January 2017, approximately 71 months)
