Primary | Number of Participants With Either an Infection or a Grade III or IV Adverse Event (National Cancer Institute Common Toxicity Criteria for Adverse Events [NCI CTCAE], Version 3.0) | A Grade III Adverse Event (AE) is severe; defined as considerable interference with the subject's daily activities, medical intervention/therapy required and hospitalization possible. A Grade IV AE is life-threatening; defined as extreme limitation in activity, significant medical intervention/therapy required, hospitalization probable. Because of the small sample size and the small number of subjects who completed Week 104, the analysis were limited to descriptive statistics only. |
24 months | No |
Secondary | Change From Baseline in Disease Activity Score 28-4 C-reactive Protein (DAS28-4(CRP)) | The DAS28-4(CRP) score is a measure of the subject's disease activity. DAS28-4(CRP) is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity and CRP. DAS28 provides a number on a scale (0 to 10) indicating current disease activity. A score above 5.1 means high disease activity and a score below 3.2 indicates low disease activity. Change from baseline at 24 months was analyzed for DAS28-4 (CRP). | Baseline, 24 months | No |
Secondary | Number of Participants With American College of Rheumatology Responses (ACR20, ACR50, and ACR70) | ACR20 response was defined as satisfying the following 3 criteria improvement from baseline: = 20% in tender joint count; = 20% in swollen joint count; = 20% improvement from baseline in 3 of the following 5 criteria: Subject's Global Assessment of Pain Subject's Global Assessment of Disease Activity Physician's Global Assessment Subject's Self-Assessment Erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) Note: The definitions of ACR50 and ACR70 are the same as ACR20, except that the 20% value in the above definition is replaced by 50% and 70% values, respectively. |
Baseline, 24 months | No |
Secondary | Number of Participants With American College of Rheumatology (ACR) Major Clinical Response and/or Remission | Major clinical response is an ACR70 response defined as improvement from baseline: =70% in tender joint count; =70% in swollen joint count; =70% in 3 of the following: Patient Pain Assessment, Patient Global Assessment, Physician Global Assessment, Patient Self-Assessed Disability, ESR or CRP for =169 consecutive days. Remission: =5 requirements fulfilled for =2 consecutive months: Duration of morning stiffness <15 minutes, No fatigue, No joint pain, No joint tenderness or pain on motion, No soft tissue swelling in joints or tendon sheaths, ESR <30 mm/hour for women and <20 mm/hour for men. |
24 months | No |
Secondary | Number of Participants With European League Against Rheumatism (EULAR) Response and Remission Using Disease Activity Score 28-4 (DAS28-4)C-reactive Protein (CRP) | EULAR remission = DAS28-4(CRP) < 2.6 (Fransen et al. 2004. EULAR response categories (van Gestel et al. 1999): Good response = final DAS28-4(CRP) < 3.2 and decreased > 1.2 points from baseline Moderate response = final DAS28-4(CRP) = 3.2 but = 5.1 and decreased > 0.6 points from baseline or final DAS28-4(CRP) > 5.1 and decreased > 1.2 from baseline. |
Baseline, 24 months | No |
Secondary | Change From Baseline in Short Form 36 (SF 36) Summary and Subscale Scores | The SF-36 is a questionnaire used to assess physical functioning and is made up of eight domains: Physical Functioning (PF), Role Physical (RP), Bodily Pain(BP), General Health (GH), Vitality (VT), Social Functioning (SF), Role-Emotional (RE),Mental Health (MH). Transforming and standardizing these domains leads to the calculation of the Physical (PCS) and Mental (MCS) Component Summary measures. Scores ranging from 0 to 100, with 0=worst score (or quality of life) and 100=best score. | Baseline, 24 Months | No |
Secondary | Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) | The Stanford HAQ-DI is a patient-reported questionnaire specific for RA. It consists of 20 questions referring to eight component sets: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. The questionnaire was provided in a certified translation of the local languages at the participating sites and was scored based on the instructions from the Stanford University Medical Center.The questions are evaluated on a 4-point scale: 0=without any difficulty, 1= with some difficulty, 2= with much difficulty, and 3= unable to do. Higher scores= greater dysfunction. | Baseline, 24 Months | No |
Secondary | Change From Baseline in Functional Assessment for Chronic Illness Therapy-Fatigue (FACIT-F) | FACIT-F is a 13-item questionnaire. Patients scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the patient's response to the questions (with the exception of 2 negatively stated), the greater the patient'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 patient'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). A higher score reflects an improvement in the patient's health status. | Baseline, 24 Months | No |
Secondary | DAS28-4 Erythrocyte Sedimentation Rate(ESR) | The DAS28-4(ESR) score is a measure of the subject's disease activity. It is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity (mm), and ESR. DAS28-4(ESR) scores range from 0 - 10, where a score of less than or equal to 3.2 implies well controlled disease and greater than or equal to 5.1 implies active disease In this trial, CRP rather than ESR was used, unless the CRP value was missing at both Day 1 and screening, in which case ESR value was used. | 24 Months | No |
Secondary | Change From Baseline in Rheumatoid Factor (RF) | Serum levels of rheumatoid factor at baseline, month 24 and change from baseline to month 24. | Baseline, 24 Months | No |
Secondary | Change From Baseline in Cyclic Citrullinated Peptide (CCP) Antibodies/Cytokines | Because of the different laboratory methods that were used to measure anti-CCP antibody levels, no summary statistics were calculated. | Baseline, 24 Months | No |
