The HAQ-DI score is defined as the average of the scores of eight functional categories (dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities), usually completed by the participant. Responses in each functional category are collected as 0-3 \[0 (without any difficulty) to 3 (unable to do a task in that area), with or without aids or devices\]. The eight category scores are averaged into an overall HAQ-DI score on a scale from 0-3 \[0 (no disability) to 3 (completely disabled)\] when 6 or more categories are non-missing, total possible score is 3. If more than 2 categories are missing, the HAQ-DI score is set to missing. Negative change from baseline indicates improvement (less disability).

Change From Baseline in the Modified Total Sharp Score (mTSS) at Week 24
Participant's radiographs of bilateral hands, wrists and feet are taken and evaluated through central review using the mTSS method. The mTSS (range \[0-448\]) is defined as the erosion score (range \[0-280\]) plus the joint space narrowing (JSN) score (range \[0-168\]). An erosion score of 0 to 5 is given to each joint in the hands and wrists, and a score of 0 to 10 is given to each joint in the feet \[where 0 indicates no erosion while 5 or 10 indicates extensive loss of bone (maximum erosion\]). JSN is scored from 0 to 4 \[0 indicating no/normal JSN and 4 indicating complete loss of joint space\]. The maximal TSS is 448. Positive change in value indicates progression of disease (more erosion of bone, less joint spaces).

The descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Rating gets recorded on a vertical VAS in which the endpoints are labeled best imaginable health state is 100 (on the top) and worst imaginable health state is 0 (on the bottom). Higher scores of EQ VAS indicate better health.

The WPAI is a questionnaire that measures impairments in work activities in participants with RA which consists of 6 questions: currently employed; work time missed due to RA; work time missed due to other reasons; hours actually worked; degree RA affected productivity while working (0-10 VAS, with 0 indicating no effect and 10 indicating RA completely prevented the participant from working); degree RA affected productivity in regular unpaid activities (0-10 VAS, with 0 indicating no effect and 10 indicating RA completely prevented the participant's daily activities). Outcomes are expressed as impairment percentages, higher numbers indicate greater impairment and less productivity. A negative change from baseline indicates improvement.
Time frame: Baseline; Weeks 4, 12, 24, 36, and 52
