Outcomes

Primary Outcomes

The ACR core set measures are: 1. Tender joint count 2. Swollen joint count 3. Subject Assessment of arthritis pain 4. Subject's Global Assessment of disease activity (SGA) 5. Physician's Global Assessment of disease activity (PGA) 6. Health Assessment Questionnaire Disability Index (HAQ-DI) 7. Acute Phase Reactant (i.e., hs-CRP - high sensitivity C-reactive protein)

Time frame: Up to 12 Weeks

Secondary Outcomes

The ACR core set measures are: 1. Tender joint count 2. Swollen joint count 3. Subject Assessment of arthritis pain 4. Subject's Global Assessment of disease activity (SGA) 5. Physician's Global Assessment of disease activity (PGA) 6. Health Assessment Questionnaire Disability Index (HAQ-DI) 7. Acute Phase Reactant (i.e., hs-CRP - high sensitivity C-reactive protein)

Time frame: Week 12

Percentage of Subjects Achieving ACR50 Response Rate Compared to Placebo at Week 12

Percentage of subjects achieving at least 50% improvement from baseline (ACR50) in tender and swollen joint counts (ACR core set measures 1 and 2) and at least 50% improvement from baseline in the 3 of the 5 remaining ACR core set measures at Week 12 compared to placebo. The ACR core set measures are: 1. Tender joint count 2. Swollen joint count 3. Subject Assessment of arthritis pain 4. Subject's Global Assessment of disease activity (SGA) 5. Physician's Global Assessment of disease activity (PGA) 6. Health Assessment Questionnaire Disability Index (HAQ-DI) 7. Acute Phase Reactant (i.e., hs-CRP - high sensitivity C-reactive protein)

Percentage of Subjects Achieving ACR70 Response Rate Compared to Placebo at Week 12

Percentage of subjects achieving at least 70% improvement from baseline (ACR70) in tender and swollen joint counts (ACR core set measures 1 and 2) and at least 70% improvement from baseline in the 3 of the 5 remaining ACR core set measures at Week 12 compared to placebo. The ACR core set measures are: 1. Tender joint count 2. Swollen joint count 3. Subject Assessment of arthritis pain 4. Subject's Global Assessment of disease activity (SGA) 5. Physician's Global Assessment of disease activity (PGA) 6. Health Assessment Questionnaire Disability Index (HAQ-DI) 7. Acute Phase Reactant (i.e., hs-CRP - high sensitivity C-reactive protein)

Time frame: Week 12

Change From Baseline in SDAI (Simplified Disease Activity Index) at Week 12

The SDAI Scores indicate how active a patient's rheumatoid arthritis (RA) is currently. The SDAI is the sum of 5 outcome parameters: tender joint score (0 to 28), swollen joint score (0 to 28), Patient's Global Score of disease activity (0 to 10), Physician's Global Score of disease activity (0 to 10) and C-reactive protein (CRP, 0 to 10).General SDAI Score Interpretation is as follows: 0.0 - 3.3 Remission 3.4 - 11.0 Low Activity 11.1 - 26.0 Moderate Activity 26.1 - 86.0 High Activity

Time frame: Week 12

Change From Baseline in CDAI (Clinical Disease Activity Index) at Week 12

The CDAI is a useful clinical composite score for following patients with rheumatoid arthritis (RA). The CDAI is the sum of 4 outcome parameters: tender joint score (0 to 28), swollen joint score (0 to 28), Patient's Global Score of disease activity (0 to 10) and Physician's Global Score of disease activity (0 to 10). The CDAI Score Interpretation is as follows: 0 to 2.8: Remission 2.9 to 10: Low Disease Activity 10.1 to 22: Moderate Disease Activity 22.1 to 76: High Disease Activity

Time frame: Week 12

Change From Baseline in DAS28-CRP (Disease Activity Score [DAS] Based on High-sensitivity C-reactive Protein [Hs-CRP]) at Week 12

Disease Activity Score (DAS) modified to include 28 joint count (DAS28) consists of composite score of following variables: 28 tender joint count (TJC28) ranging from 0 to 28, 28 swollen joint count (SJC28) ranged from 0 to 28, C-reactive protein (CRP) (milligrams per liter) and subject's global assessment of disease activity (SGA) ranging from 0 (no disease activity) to 10 (extremely active disease). DAS28-CRP was calculated using following formula: DAS28-CRP=0.56\*square root (sqrt)(TJC28)+0.28\*sqrt(SJC28)+0.36\*natural log(CRP+1)+0.014\*SGA+0.96. DAS28-CRP ranged from 0.96-9.4, where lower scores indicated less disease activity and remission is DAS28-CRP \<2.6. A decrease in DAS28-CRP indicated an improvement in participant's condition.

Time frame: Week 12

Change From Baseline in HAQ-DI (Health Assessment Questionnaire Disability Index) at Week 12

The HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty \[0 (without any difficulty), 1 (with some difficulty), 2 (with much difficulty), and 3 (unable to do)\] in 8 functional area categories: (1) dressing and grooming; (2) arising; (3) eating; (4) walking; (5) hygiene; (6) reaching; (7) gripping; and (8) performing other daily activities. Scores from each functional area category (total 8 categories) were averaged to calculate the HAQ-DI score, which ranged from 0 (no disability) to 3 (severe disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition.

Time frame: Week 12

Number of Subjects With Treatment-related Adverse Events

Subjects in the Safety Population (258, subjects who were randomly assigned to treatment and who received at least one dose of study drug). The number of subjects in the Safety Population is 258 subjects, which is 1 less than the Randomized Population of 259 subjects, since 1 randomized subject did not receive any study drug.
