Outcomes

Primary Outcomes

Percentage of Participants With 28-Joint Disease Activity Score of C-reactive Protein (DAS28[CRP]) Low Disease Activity at Week 26

Percentage of participants achieving low disease activity as defined by a clinical response (DAS28\[CRP\] \< 3.2). The DAS28 is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, C-reactive protein, and general health are included in the DAS28 score. Scores on the DAS28 range from 0 to 10. A DAS28 score \>5.1 indicates high disease activity, a DAS28 score \<3.2 indicates low disease activity, and a DAS28 score \<2.6 indicates clinical remission.

Time frame: Week 26

Secondary Outcomes

Percentage of Participants With DAS28(CRP) Remission at Week 26

Disease remission was defined as a disease activity score, based on CRP, for 28 joints that was \< 2.6 (DAS28\[CRP\] \< 2.6). The DAS28 is a validated index of rheumatoid arthritis disease activity.

Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) Score at Week 26

The Health Assessment Questionnaire - Disability Index (HAQ-DI) is a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 very severe, high-dependency disability. HAQ remission indicating normal physical function is defined by HAQ-DI score of \< 0.5. Negative change from Baseline in the overall score indicates improvement.

Time frame: Baseline, Week 26

Percentage of Participants With a Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) ≤ -0.22 at Week 26

The Health Assessment Questionnaire - Disability Index is a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. The minimal clinically important difference (MCID) defined for the HAQ-DI is a change from Baseline of ≥ 0.22. HAQ remission indicating normal physical function is defined by HAQ-DI score of \< 0.5. Negative change from Baseline in the overall score indicates improvement.

Time frame: Baseline, Week 26

Change From Baseline in Modified Total Sharp Score (mTSS) at Week 26

The modified Total Sharp Score (mTSS) is a measure of change in joint health from digitized images of radiographs of hands and feet. Joints were scored for erosions on a scale of 0 (no damage) to 5 (complete collapse) and joint space narrowing on a scale of 0 (no damage) to 4 (ankylosis or complete dislocation). Erosion scores and narrowing scores were added to obtain the mTSS (range = 0 \[normal\] to 398 \[maximal disease\]). An increase in mTSS from Baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.

Time frame: Baseline, Week 26

Percentage of Participants With No Radiographic Progression at Week 26

"No radiographic progression" was defined as a change from Baseline in modified Total Sharp Score (mTSS) at Week 26 of ≤ 0.5. mTSS is a measure of change in joint health from digitized images of radiographs of hands and feet. Joints were scored for erosions on a scale of 0 (no damage) to 5 (complete collapse) and joint space narrowing on a scale of 0 (no damage) to 4 (ankylosis or complete dislocation). Erosion scores and narrowing scores were added to obtain the mTSS (range = 0 \[normal\] to 398 \[maximal disease\]). An increase in mTSS from Baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.

Time frame: Baseline, Week 26

Percentage of Participants With Simplified Disease Activity Index (SDAI) Remission at Week 26

SDAI is a measure of disease activity derived as follows: SDAI = SJC28 + TJC28 + GH (cm) + PhGA (cm) + CRP (mg/dL), where TJC28 and SJC28 represent total tender joint count and total swollen joint count, respectively, based on 28 joints (including the left and right side of the body), GH = Patient's Global Assessment of Disease Activity, and PhGA = Physician's Global Assessment of Disease Activity (both measured on a visual analogue scale with a range of 0 \[none\] to 10 \[severe\]), and CRP is C-reactive protein measured in mg/dL. SDAI total score = 0 to 86. SDAI ≤ 3.3 indicates disease remission, \> 3.4 to 11 = low disease activity, \> 11 to 26 = moderate disease activity, and \> 26 = high disease activity.

Time frame: Week 26

Percentage of Participants With Clinical Disease Activity Index (CDAI) Remission at Week 26

CDAI is a measure of disease activity derived as follows: CDAI = SJC28 + TJC28 + GH (cm) + PhGA (cm) where TJC28 and SJC28 represent total tender joint count and total swollen joint count, respectively, based on 28 joints (including the left and right side of the body), GH = Patient's Global Assessment of Disease Activity, and PhGA = Physician's Global Assessment of Disease Activity (both measured on a visual analogue scale with a range of 0 \[none\] to 10 \[severe\]). CDAI total score = 0 to 76. CDAI ≤ 2.8 indicates disease remission, \> 2.8 to 10 = low disease activity, \> 10 to 22 = moderate disease activity, and \> 22 = high disease activity.
