Primary outcomes

  1. Change From Baseline in Disease Activity Index Score 28 Using C-reactive Protein (DAS28-CRP) at Week 12

    Change from baseline in DAS28-CRP at Week 12 were reported. The DAS28 is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity, and C-reactive protein (CRP; in milligrams per liter \[mg/L\]). The set of 28 joint count was based on evaluation of the shoulder, elbow, wrist, metacarpophalangeal (MCP) MCP1 to MCP5, proximal interphalangeal (PIP) PIP1 to PIP5 joints of both the upper right extremity and the upper left extremity as well as the knee joints of lower right and lower left extremities.
