- Primary Outcome Measures
Name Time Method Percentage of Participants Who Achieved an American College of Rheumatology (ACR) 20% Improvement (ACR20) Response at Week 12 Week 12 ACR20 response is achieved when the participant has: ≥20% improvement (reduction) from baseline in tender joint count based on 68 joints (TJC68), swollen joint count based on 66 joints (SJC66) and in at least 3 of the following 5 items: physician's global assessment of disease activity (PGA) and subject's global assessment of disease activity (SGA) assessed using visual analog scale (VAS) on a scale of 0-100 (0 and 100 indicating no disease activity and maximum disease activity)participant's pain assessment using VAS on a scale of 0-100 (0 and 100 indicating no pain and unbearable pain) health assessment questionnaire-disability index (HAQ-DI) score contains 20 questions,8 components: dressing/ grooming, arising, eating, walking, hygiene, reach, grip and activities and scored on a scale of 0-3 (0 and 3 indicating without difficulty and unable to do); high-sensitivity C-reactive protein (hsCRP). Participants with missing outcomes were set as non-responders.
- Secondary Outcome Measures
Name Time Method Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Week 12 Baseline; Week 12 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 (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 (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 Modified Total Sharp Score (mTSS) at Week 24 Baseline; 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, with 0 indicating normal or no narrowing and 4 indicating complete loss of joint space. The maximal TSS is 448. Negative change in value indicates improvement (less erosion of bone, normal joint spaces).
Percentage of Participants Who Achieved Disease Activity Score for 28 Joint Count Using C-Reactive Protein [DAS28 (CRP)] < 2.6 at Week 12 Week 12 The DAS28 score is a measure of the participant's disease activity calculated using the tender joint counts (28 joints), swollen joint counts (28 joints), SGA (VAS: 0 = no disease activity to 100 = maximum disease activity), and hsCRP (CRP = hsCRP) for a total possible score of 1 to 9.4. Higher values indicate higher disease activity. Participants with missing outcomes were set as non-responders.
Percentage of Participants Who Achieved DAS28 (CRP) ≤ 3.2 at Week 12 Week 12 The DAS28 score is a measure of the participant's disease activity calculated using the tender joint counts (28 joints), swollen joint counts (28 joints), SGA (VAS: 0 = no disease activity to 100 = maximum disease activity), and hsCRP for a total possible score of 1 to 9.4. Higher values indicate higher disease activity. Participants with missing outcomes were set as non-responders.
Change From Baseline in 36-Item Short Form Survey (SF-36) Physical Component Summary (PCS) Score at Week 12 Baseline; Week 12 The SF-36 is a 36-item, self-reported, generic, comprehensive, and health-related quality of life questionnaire based on 8 health domains in 2 components: physical well-being (physical functioning, role-physical, bodily pain, general health perceptions), mental well-being (vitality, social functioning, role-emotional, and mental health). Each domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale with highest possible score of 100. Higher scores indicate better health status or functioning. Positive change in value indicates improvement and better quality of life.
Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Score at Week 12 Baseline; Week 12 FACIT-Fatigue scale is a brief, 13-item, symptom-specific questionnaire that specifically assesses the self-reported severity of fatigue and its impact upon daily activities and functioning in the past 7 days. The FACIT-Fatigue uses 0 (not at all) to 4 (very much) numeric rating scales for a total possible score of 0 to 52. Positive change in value indicates improvement (no or less severity of fatigue).

Change From Baseline in mTSS at Week 52 Baseline; Week 52 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, with 0 indicating normal or no narrowing and 4 indicating complete loss of joint space. The maximal TSS is 448. Negative change in value indicates improvement (less erosion of bone, normal joint spaces).
