Geometric Mean Maximum Observed Serum Concentration (Cmax) of Elotuzumab Following Cycle 1, Day 1 Dose Administration - Grouping by Cockcroft-Gault Creatinine Clearance Method
The quantification of elotuzumab in human serum was performed using a validated Enzyme-linked immunoassay (ELISA). Cycle 1, day 1 sample times for all participants: 0 hour (h) pre-dose, end of infusion, 30 minutes (min) post end of infusion, 2 h, 4 h , and 24 h post end of infusion. Trough samples were obtained in subsequent cycles and at 30 day and 60 day follow-up visits at end of treatment. ESRD had 2 additional samples: immediately prior to and immediately after dialysis. Cmax was measured in micrograms per milliliter (µg/mL). Pharmacokinetic (PK) parameter renal function group assignment criteria differed slightly from the criteria for safety and efficacy analyses (specifically for the SRI group). PK criteria: All participants with at least one pretreatment value ≥ 90 mL/min were assigned to the NRF group. All those with at least one pretreatment value \< 30 mL/min were assigned to the SRI group. All those with a screening diagnosis of ESRD, were assigned to the ESRD group.
Time frame: Day 1 of Cycle 1 to 28 days post dose
Geometric Mean Area Under Serum Concentration-Time Curve From Time Zero to Time of Last Quantifiable Concentration AUC(0-T) and From Time Zero Extrapolated to Infinite Time AUC(INF) of Elotuzumab Following Cycle 1, Day 1 - Grouping by C-G CrCl Method
The quantification of elotuzumab in human serum was performed using validated ELISA. Cycle 1, day 1 sample times for all participants: 0 hour (h) pre-dose, end of infusion, 30 minutes (min) post end of infusion, 2 h, 4 h , and 24 h post end of infusion. Trough samples were obtained in subsequent cycles and at 30 day and 60 day follow-up visits at end of treatment. ESRD participants had 2 additional sample times: immediately prior to and immediately after dialysis. AUC was measured in µg\*h/mL. PK parameter renal function group assignment criteria differed slightly from the criteria for safety and efficacy analyses (specifically for the SRI group). PK criteria: All participants with at least one pretreatment value ≥ 90 mL/min were assigned to the NRF group. All those with at least one pretreatment value \< 30 mL/min were assigned to the SRI group. All those with a screening diagnosis of ESRD, were assigned to the ESRD group

Number of Participants With Serious Adverse Events (SAEs), Adverse Events (AEs) Leading to Discontinuation, and Who Died
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.
Time frame: From first dose (Day 1) to last dose plus 60 days (Assessed up to July 2016, approximately 54 months)
Number of Participants With Persistent Elotuzumab Anti-drug Antibodies (ADA) and Number of Participants ADA Positive at Cycle 2 Pre-dose.
Serum samples were evaluated for the presence of ADAs using a validated bridging electrochemiluminescence (ECL) immunoassay. Samples in: Cycle 1, Day 1 0 h (pre-dose), Cycle 2, Day 1(Study Day 29), 0 h (pre-dose; 672 h post-dose), Cycle 3, Day 1, 0 h and in cycle thereafter, at end of study/discontinuation, and at 30 and 60 day follow up visits post treatment. ADA Positive Participant: baseline negative with at least one ADA positive sample at any time after initiation of treatment or baseline positive with at least one ADA positive sample at any time after initiation of treatment with a titer 9-fold greater than the baseline; Persistent Positive: ADA positive at 2 or more sequential timepoints at least 12 weeks apart; Last Sample Positive: Not persistent positive and ADA Positive Sample in the last sampling timepoint; Other Positive: not persistent positive with ADA negative sample in the last sampling; ADA Negative: no ADA positive sample after the initiation of treatment.
Time frame: From first dose (Day 1) to last dose plus 60 days, up to Primary Endpoint (June 2014), approximately 2 years
