Week 12

ACR20 is calculated as a 20% improvement from Baseline in Tender Joint Count 68 (TJC68) and Swollen Joint Count 66 (SJC66) and a 20% improvement in 3 of the following 5 measures: Patient's Global Assessment of Arthritis Disease Activity (PtGA) (visual analogue scale (VAS) with values from 0=best to 100=worst), Physician Global Assessment of Arthritis Disease Activity (PhGA) (VAS with values from 0=best to 100=worst), Patient Assessment of Arthritis Pain (VAS with values from 0=no pain and 100=most severe pain), Health Assessment Questionnaire-Disability Index (HAQ-DI) (ranges from 0 to 3 where 0 = least difficulty and 3 = extreme difficulty) and an acute-phase reactant (high sensitivity C-reactive Protein mg/L (hsCRP)). For the purpose of all analyses up to week 12, the placebo arms were pooled into a single placebo arm to primarily serve as a reference for the comparison of active treatment arms.

Week 24

DAS28 is a modification of the original DAS and is based on a count of 28 swollen and tender joints and is used to evaluate a participant's response to treatment. DAS 28 CRP utilizing joint scores from the following 28 joints: elbows, shoulders, elbow, wrists, metacarpal- phalangeal I-V, proximal interphalangeal I-V and knees and is calculated using the following formula: DAS28 (CRP) = 0.56\*√(TJC28) +0.28\*√(SJC28)+0.014\*GH+0.36\*ln(CRP+1)+0.96. Where TJC - Tender joint Count, SJC= Swollen Joint Count, (GH=participant assessment of disease activity using a 100 millimeter \[mm\] visual analogue scale with 0 = best, 100 = worst) and CRP= C reactive Protein (in \[milligrams/liter\] mg/L).
