Primary

MeasureTime frameDescription
Change From Baseline in Disease Activity Score Based on 28-joints Count and Erythrocyte Sedimentation Rate (DAS28-ESR) at Week 24Baseline, Week 24The DAS28-ESR was derived from assessments of erythrocyte sedimentation rate (ESR), tender joint count (TJC), swollen joint count (SJC), and Patient Global Assessment of disease activity (PGA) according to 100-millimeter (mm) Visual Analog Scale (VAS). DAS28-ESR scores were calculated as \[0.56 × square root of TJC\] + \[0.28 × square root of SJC\] + \[0.70 × natural log (ESR)\] + \[0.014 × VAS\]. TJC was defined as the number of painful joints and SJC was defined as the number of swollen joints, each assessed on 28 joints. ESR was measured in millimeters per hour (mm/h). DAS28-ESR scores could range from 0 to 10, where higher scores represented higher disease activity. The change from Baseline to Week 24 was averaged among all participants, where negative changes indicated an improvement in disease activity.

Change From Baseline in Disease Activity Score Based on 28-joints Count and Erythrocyte Sedimentation Rate (DAS28-ESR) at Week 24

The DAS28-ESR was derived from assessments of erythrocyte sedimentation rate (ESR), tender joint count (TJC), swollen joint count (SJC), and Patient Global Assessment of disease activity (PGA) according to 100-millimeter (mm) Visual Analog Scale (VAS). DAS28-ESR scores were calculated as \[0.56 × square root of TJC\] + \[0.28 × square root of SJC\] + \[0.70 × natural log (ESR)\] + \[0.014 × VAS\]. TJC was defined as the number of painful joints and SJC was defined as the number of swollen joints, each assessed on 28 joints. ESR was measured in millimeters per hour (mm/h). DAS28-ESR scores could range from 0 to 10, where higher scores represented higher disease activity. The change from Baseline to Week 24 was averaged among all participants, where negative changes indicated an improvement in disease activity.

Change From Baseline in Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ) Total Score at Weeks 24 and 52

BRAF-MDQ assessed the overall experience and impact of disease related fatigue, using four dimensions (physical fatigue \[4 items\], living with fatigue \[7 items\], cognitive fatigue \[5 items\], and emotional fatigue \[4 items\]). A total fatigue score (range 0 to 70) was obtained by summing the 20 item scores ranging from 0 to 3, except for item 1 (0-10), item 2 (0-7) and item 3 (0-2). Higher scores reflect greater fatigue. If only 1 domain was missing it was replaced by the mean of the others; otherwise, the total score was not calculated. The changes from Baseline to any time point were averaged among all participants, where negative changes indicated better quality of life.

Change From Baseline in Fluctuations of Disease Activity in Rheumatoid Arthritis (FLARE) Questionnaire Score at Weeks 2, 4, 8, 12, 16, 20, 24, 28, 40, 52, and 64

FLARE is a 13-item questionnaire assessed disease flares between two medical consultations. Each item score ranged from 0 (completely untrue) to 10 (absolutely true) on a 6-step scale. The FLARE questionnaire global score (range = 0-10) is a mean score of 11 of the 13 items \[items 6 ('doses of pain killers or anti-inflammatory medication') and 13 ('need for help') not taken into account\], with the highest score corresponding to the highest disease activity. The global score was computed if at least the scores of 6 items were available. The changes from Baseline to any time point were averaged among all participants, where negative changes indicated better outcome.

FACIT-F is a 13-item questionnaire. Participants scored each item on a 5-point scale: 0 (not at all) to 4 (very much). Larger the participant's response to the questions (with the exception of 2 negatively stated questions), greater was the participant'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 participant'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). The changes from Baseline to any time point were averaged among all participants, where negative changes indicated an increase in fatigue.

Time frame: Baseline, Weeks 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, and 64

Change From Baseline in Rheumatoid Arthritis Impact of Disease (RAID) Score at Weeks 12, 24, 28, 40, 52, and 64

RAID assessed the impact of rheumatoid arthritis on participant's quality of life. It comprised 7 domains: pain, function, fatigue, physical and psychological well-being, sleep disturbance and coping. Each domain was a single question scored from 0 (best) to 10 (worst) on a continuous numerical rating scale (NRS). Each domain also had a specific weight assigned by a participant survey and RAID total score ranged from 0 (best) to 10 (worst). If only 1 domain was missing it was replaced by the mean of the others; otherwise, RAID score was not calculated. The changes from Baseline to any time point were averaged among all participants, where negative changes indicated better quality of life.
