A Study to Compare the Response to Treatment With Abatacept vs Adalimumab, on Background Methotrexate, in Adults With Early, Seropositive, and Shared Epitope-positive Rheumatoid Arthritis and an Inadequate Response to Methotrexate

The purpose of this study is to evaluate the superiority in efficacy of abatacept compared with adalimumab, on background methotrexate, in adults with early, seropositive, and shared epitope-positive rheumatoid arthritis and an inadequate methotrexate response.

Secondary outcomes

    • Physician global assessment of disease activity (a 0-100mm visual analog scale with 100 mm being the worst case)
    • Participant assessment of physical function Health Assessment Questionnaire Disability Index (HAQ-DI) (increasing scores for the 8 disability categories indicate increasing level of difficulty). HAQDI is calculated by summing the adjusted categories scores and dividing by the number of categories answered
    • C-reactive protein (increasing levels indicate increasing level of disease) Baseline value is the last assessment taken prior to first dose of single-blind study medication. Change from Baseline=Post-baseline - Baseline value.

  29. Adjusted Mean Change From Baseline in American College of Rheumatology (ACR) Core Components 6 Over Time for All Participants

    Time frame: Baseline, day 29, 57, 85, 113, 141, 169

    • Participant assessment of physical function Health Assessment Questionnaire Disability Index (HAQ-DI). For the eight disability categories (Dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities), there is an aids or devices variables to record the type of assistance. If aids or devices and/or assistance from another person are checked for a category, the score is set to 2 (much difficulty), if the original score is 0 (no difficulty) or 1 (some difficulty). HAQ-DI is then calculated by summing the adjusted categories scores and dividing by the number of categories answered (increasing scores for the 8 disability categories questionnaire indicate increasing level of difficulty with 0 being the lowest score "without any difficulty" and 3 being the highest score "unable to do".

    Baseline value is the last assessment taken prior to first dose of single-blind study medication. Change from Baseline=Post-baseline - Baseline value.

    • Tender joint count (standard 68 joint count)
    • Swollen joint count (standard 66 joint count)
    • Participant global assessment of pain (a 0-100mm visual analog scale with 100 mm being the worst pain)
    • Participant global assessment of disease activity (a 0-100mm visual analog scale with 100 mm being the highest disease activity)

  31. Adjusted Mean Change From Baseline in 36-item Short Form Survey (SF-36) Over Time for SE+ Participants

    Time frame: Up to week 24

    SF-36 is a generic 36-item questionnaire measuring health-related quality of life, which covers 8 health dimensions within 2 components. The physical component summary (PCS) consists of these 4 subscales: Physical functioning, Role-physical, Bodily pain, General health. The mental component summary (MCS) consists of these 4 subscales: Vitality, Social functioning, Role-emotional, Mental health. Participants self-report on items in a subscale that have between 2-6 choices per item using Likert-type responses (e.g. none of the time, some of the time). Summations of item scores of the same subscale give the subscale scores, which are transformed into a range from 0 to 100, with a higher score indicating better quality of life. The 8 subscales will be scored using norm-based methods that have standardized the T-scores to a mean of 50 and a standard deviation of 10 in the general population.

  33. Adjusted Mean Change From Baseline in 36-item Short Form Survey (SF-36) at Week 104 for SE+ Participants

    Time frame: Up to week 24

    The SF-36 v2.0, which covers 8 health dimensions within 2 components. The physical component summary (PCS) of the SF-36 consists of these 4 subscales: Physical functioning, Role-physical, Bodily pain, General health. The mental component summary (MCS) of the SF-36 consists of these 4 subscales: Vitality, Social functioning, Role-emotional, Mental health. The scores range from 0 to 100, with a higher score indicating better quality of life. The 2 summary scores (PCS and MCS) will be calculated by taking a weighted linear combination of the 8 individual subscales. Baseline value is the last assessment taken prior to first dose of single-blind study medication. Change from Baseline = Post-baseline - Baseline value.
