Primary outcomes

  1. Number of Participants American College of Rheumatology 50% (ACR50) Response at Week 12

    Time frame: Week 12

    A participant was a responder if the following 3 criteria for improvement from baseline were met:

    • ≥50% improvement in 68-tender joint count;
    • ≥50% improvement in 66-swollen joint count; and
    • ≥50% improvement in at least 3 of the 5 following parameters:

Secondary outcomes

  1. Number of Participants American College of Rheumatology 20% (ACR20) Response

    Time frame: Week 4, 8, 12, 16, 20 and 24

    ACR20 response: greater than or equal to (>=) 20 percent (%) improvement in painful and tender joint count; >= 20% improvement in swollen joint count; and >= 20% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP)at each visit.

  2. Number of Participants Achieving American College of Rheumatology 50% (ACR50) Response

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    ACR50 response: greater than or equal to (>=) 50 percent (%) improvement in painful and tender joint count; >= 50% improvement in swollen joint count; and >= 50% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP) at each visit.

  3. Number of Participants Achieving American College of Rheumatology 70% (ACR70) Response

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    ACR70 response: greater than or equal to (>=) 70 percent (%) improvement in painful and tender joint count; >= 70% improvement in swollen joint count; and >= 70% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP) at each visit.

  4. Change From Baseline in Disease Activity Score Based on 28-Joints Count-High-Sensitivity C-reactive Protein (DAS28-hsCRP)

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    Disease Activity Score (DAS) based on a 28 joint count hsCRP consisted of composite numerical score of following variables: tender joint count (TJC28), swollen joint count (SJC28), hsCRP (mg/mL), and participant's global assessment of disease activity. DAS28-hsCRP was calculated using following formula: DAS28-hsCRP equals to (=) 0.56*square root (sqrt) (TJC28) plus (+) 0.28*sqrt (SJC28) + 0.36*natural log(hsCRP+1) + 0.014*participant's global assessment of disease activity + 0.96. Scores ranged 0-9.4, where lower scores indicated less disease activity. Change = value at observation minus value at baseline.

  5. Change From Baseline in Clinical Disease Activity Index (CDAI)

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    CDAI is calculated as the sum of tender joint count (TJC), swollen joint count (SJC), Patient's Global Assessment of Disease Activity as assessed by Multi-dimensional Health Assessment Questionnaire (MDHAQ) subscore, and Investigator's Global Assessment of Disease Activity - Visual Analog Scale (VAS in cm). 28 joints are examined. The range for the CDAI is 0 - 76 with a negative change in CDAI score indicating an improvement in disease activity and a positive change in score indicating a worsening of disease activity.

  6. Changes From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Total Score

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    HAQ-DI score was an evaluation of the functional status for a participant. The 20-question instrument assessed the degree of difficulty a person had in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area were scored from 0, indicated no difficulty, to 3, indicated inability to perform a task in that area. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range: 0-3 where 0 = least difficulty and 3 = extreme difficulty.

  7. Percent Change From Baseline in Participant's Assessment of Pain Based on Visual Analog Scale (VAS) Score

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    The participants were asked to assess their level of pain by marking a vertical tick on a 100 mm horizontal VAS scale. The scale ranged from 0-100 mm, where 0 indicated no pain and 100 indicated worst possible pain.

  8. Change From Baseline in Patient's Global Assessment of Arthritis

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    Participants answered: "Considering all the ways your arthritis affects you, how are you feeling today?" Participants responded by using a 0 - 100 mm Visual Analog Scale where 0 = very well and 100 = very poorly. Change = score at observation minus score at baseline.

  9. Change From Baseline in Physician's Global Assessment of Arthritis

    Time frame: Weeks 4, 8, 12, 16, 20 and 24

    Physician Global Assessment of Disease Activity was measured on a 0 to 100 mm Visual Analog Scale (VAS), with 0 mm = no disease activity; very good and 100 mm = worst disease activity; very poor. Change = score at observation minus score at baseline.
