The ACR 50 definition of improvement is a 50% improvement over baseline in tender and swollen joint counts (#1 and #2) and a 50% improvement in 3 of the 5 remaining core data set measures (Participant global assessment of pain, participant global assessment of disease activity, physician global assessment of disease activity, participant assessment of physical function, and acute phase reactant value). Baseline value is the last assessment taken prior to first dose of single-blind study medication.

All participants that are shared epitope-positive (SE+) at baseline. SE+ participants with missing data at week 24 or discontinuation due to any reason before week 24 are considered non-responders

DAS28-CRP is a continuous variable which is a composite of 4 variables: the number of tender joints out of a pre-specified 28 joints, the number of swollen joints out of a pre-specified 28 joints, C-reactive protein in mg/L (CRP) and participant assessment of disease activity measure on a visual analogue scale (VAS) of 100mm. DAS28-CRP scores range from 0 to 10; higher scores indicate more active disease. DAS28-CRP is calculated using the following formula: DAS28-CRP(4) = 0.56*sqrt(TJC28) + 0.28*sqrt(SJC28) + 0.36*ln(CRP+1) + 0.014*GH + 0.96 where t28 = number of painful joints from 28 joints, sw28 = number of swollen joints from 28 joints, CRP = c-reactive protein in mg/L, and GH = general health or patient's global assessment of disease activity on a 100 mm VAS.

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.
