- Change From Baseline in Modified Total Sharp Score (mTSS) From Screening at Week 52 [ Time Frame: Baseline and week 52 ]Rate of progression in structural joint damage (PJD) by change in Total Modified Sharp Score (TMSS) from screening to Week 52 in the modified intent-to-treat (MITT) population. TMSS is the sum of the erosion score (ES) and the joint space narrowing (JSN) score and has a range of 0 to 398. The ES is the sum of joint scores collected for 46 joints and has a range of 0 to 230. The JSN is the sum of joint scores collected for 42 joints and has a range of 0 to 168. A score of 0 would indicate no change and higher scores represent a worsening of joint erosions and joint space narrowing.

- Change in Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) Score From Baseline at Week 52 [ Time Frame: Baseline, Week 52 ]FACIT-F is a 13-item questionnaire. Patients scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the patient's response to the questions (with the exception of 2 negatively stated), the greater the patient's fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the patient's response). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score). A higher score reflects an improvement in the patient's health status.
