Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics (PK): Maximum Plasma Concentration (Cmax) for Tabalumab (LY2127399)		Cycle 1, Day 1: 6 + or - hours after bortezomib (BTZ); Cycle 7, Day 1: immediately post BTZ dose and 2 hours after tabalumab
Pharmacokinetics (PK): Area Under the Plasma Concentration-time Curve From Time Zero to the Last Measurable Plasma Concentration (AUC0-tlast) of Tabalumab (LY2127399)		Cycle 1, Day 1: 6 + or - hours after bortezomib (BTZ); Cycle 7, Day 1: immediately post BTZ dose and 2 hours after tabalumab
Pharmacokinetics (PK): Area Under the Plasma Concentration-time Curve From Time Zero to Infinity (AUC0-∞) of Tabalumab (LY2127399)		Cycle 1, Day 1: 6 + or - hours after bortezomib (BTZ); Cycle 7, Day 1: immediately post BTZ dose and 2 hours after tabalumab
Number of Participants With Tumor Response (Tumor Response Rate)	Stringent Complete Response- Complete response in addition to normal free light chain ration and no clonal cells in bone marrow. Complete Response- no monoclonal protein (mp) in blood, no serum or urine mp, less than 5% plasma cells in bone marrow. Very Good Partial Response-more than 90% decrease in mp and urine protein. Partial Response- over 50% decrease in serum mp. Stable Disease- less than 25 percent decrease of monoclonal protein. Progressive Disease- 25% increase compared to lowest value of serum mp, urine mp, no measurable mp.	Baseline to disease progression (up to 421 days)
Duration of Response (DoR)	DoR is defined as the time from the date when the measurement criteria are met for CR, CRu, or PR (whichever status is recorded first) until the date of first observation of measured progressive disease. For responding participants who die without progressive disease (including death from study disease),DoR will be censored at the date of death. For responding participants not known to have died as of the data cut-off date and who do not have progressive disease, DoR will be censored at the last objective progression-free assessment date prior to the data cut-off date.	Time from Response until measured Progressive Disease (up to 455 days)
Time to Progression (TTP)	TTP is defined as the time from the date of study enrollment to the date of objectively determined progressive disease. TTP will be censored at the date of the last objective progression free disease assessment.	Baseline to date of Progressive Disease (up to 455 days)
Pharmacodynamics (PD): Change From Baseline in Absolute B-cell Count		Baseline through study completion (up to 455 days)
Pharmacodynamics (PD): Change From Baseline in B-cell Subset Fractions	CD19+ peripheral B-cells counts are based on the percentage of total leukocyte population and absolute cell counts.	Baseline, Cycle 1 and Cycle 7: prior to first tabalumab dose.
