Participant Flow

This dose-escalation study had 4 cohorts. Each cohort included 6 LY2127399 (tabalumab) participants and 2 placebo participants. Participants treated once every 2 weeks (Q2W) or once every 4 weeks (Q4W) and had a follow-up visit at Week 32. Additional visits beyond Week 32 were scheduled, as needed, for B cell count monitoring (up to 12 weeks).

Population: Randomized participants who received at least 1 dose of study drug (tabalumab or placebo) and had a baseline and at least 1 post-baseline B cell assessment.

B-lymphocyte antigen, CD20+, is an activated-glycosylated phosphoprotein expressed on the surface of all mature B cells. Percent change from baseline in B cell counts=\[(post-baseline CD20+ B cell count-baseline CD20+ B cell count)/(baseline CD20+ B cell count)\]\*100. A negative change indicates a decrease in cell count.

SECONDARY outcome

Timeframe: Baseline, Week 24

Population: Randomized participants who received at least 1 dose of study drug (tabalumab or placebo) and had a baseline and at least 1 post-baseline anti-CCP assessment using the Inova ELISA method. No participants were analyzed in the 120 mg tabalumab Q4W and Q2W cohorts.

During the analysis of anti-CCP, the analytical method was changed from the Inova ELISA method to the Roche Cobas 6000 method due to the discontinuation of a reagent used in the Inova ELISA method. The anti-CCP data are summarized separately for samples collected before and after the method change. No post-baseline samples from the 120 mg tabalumab Q4W and Q2W cohorts were analyzed using the Inova ELISA method. For both methods, a decrease in anti-CCP antibodies indicated an improvement in the participant's condition.

SECONDARY outcome

Timeframe: Baseline, Week 24

Population: Randomized participants who received at least 1 dose of study drug (tabalumab or placebo) and had a baseline and at least 1 post-baseline RF level assessment.

RF is an autoantibody (antibody directed against an organism's own tissues) most relevant in rheumatoid arthritis (RA). Higher RF levels indicate an aggressive RA and a higher risk of joint damage. A decrease in RF levels indicate an improvement in the participant's condition.

Timeframe: Baseline, Weeks 4, 16, 24, and 32

Population: Randomized participants who received at least 1 dose of study drug (tabalumab or placebo) and had a baseline and at least 1 post-baseline serum immunoglobulin assessment.

Immunoglobulins, or antibodies, are large proteins used by the immune system to identify and neutralize foreign particles such as bacteria and viruses. Their normal blood levels indicate proper immune status. Change from baseline serum immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA) levels are reported. A negative change indicates a decrease in immunoglobulin levels.

SECONDARY outcome

Timeframe: Baseline, Weeks 4, 8, 16, and 24

Population: Randomized participants who received at least 1 dose of study drug (tabalumab or placebo) and had a baseline and at least 1 post-baseline ESR assessment.

ESR is a laboratory test that provides a non-specific measure of inflammation. The test assesses the rate at which red blood cells fall in a test tube. Reference ranges are gender-specific and can vary slightly among laboratories. The normal range is approximately ≤10 millimeters per hour (mm/h) for males and ≤20 mm/h for females. Higher scores indicate greater inflammation. The percent change from baseline in ESR=\[(post-baseline ESR- baseline ESR)/(baseline ESR)\]\*100. A decrease in ESR indicates an improvement in the participant's condition.
