Study Endpoints

Primary Endpoints

Percentage of Participants Who Achieved American College of Rheumatology 20 Percent (%) Response Criteria (ACR20) Assessed Using High-Sensitivity C-reactive Protein (hsCRP) at Week 12
Week 12

ACR20 response: a participant has at least 20% improvement in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with 20% improvement in at least 3 of the following: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function measured by Health Assessment Questionnaire-Disability Index (HAQ-DI); and 5) acute phase reactant as measured by high-sensitivity C-reactive protein (hsCRP). Percentage of participants with ACR20 response using hsCRP = Number of participants with ACR20 response using hsCRP divided by total modified intent-to-treat (mITT) participants \* 100.

Secondary Endpoints
