Health Assessment Questionnaire-Disability Index (HAQ-DI): participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3, where 0 = least difficulty and 3 = extreme difficulty.

The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

DAS28-3 (CRP) was calculated from the SJC and TJC using the 28 joints count and CRP. It was calculated as DAS28-3 (CRP) = 1.15 + 1.10 * ([0.56 * square root of TJC] + [0.28 * square root of SJC] + [0.36 * natural logarithm of {CRP+1}]). Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-3 (CRP) <= 3.2 implied low disease activity and >3.2 to 5.1 implied moderate to high disease activity, and DAS28-3 (CRP) <2.6 = remission.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
