Outcomes
Primary outcome [1] 0 0
Percentage of Participants With a Response as Determined by American College of Rheumatology (ACR) 20% Improvement (ACR20) - ACR20 defined as overall score of =20 in ACR number (ACRn) calculation. Overall score defined as lowest percent improvement from baseline (BL) of following 3 measures: tender joint count (TJC; 68 joints), swollen joint count (SJC: 66 joints), and the 3rd lowest improvement achieved by at least 3 of 5 remaining ACR core parameters: physician's global assessment of disease activity, participant's global assessment of disease activity, participant's assessment of pain (visual analog assessment [VAS]), Health Assessment Questionnaire (HAQ), and C-Reactive Protein (CRP). If CRP missing, erythrocyte sedimentation rate (ESR) was used. In order for improvements in the ACRn score to be expressed as a positive result, rather than the negative changes that improvements represent, the final ACRn results were multiplied by negative 1. Last observation carried forward (LOCF) for TJC/SJC, HAQ, CRP/ESR, VAS. If change in CRP incalculable, change in ESR used. ACR20 set to Non-Responder if ACRn missing

If CRP missing, ESR was used. In order for improvements in the ACRn score to be expressed as a positive result, rather than the negative changes that improvements represent, the final ACRn results were multiplied by negative 1.

Disease Activity Score Based on 28-Joint Count and Erythrocyte Sedimentation Rate (DAS28-ESR): Adjusted Mean Change From BL at Week 48 - DAS28 was calculated according to the following formula: DAS28 equals (=) [0.56 multiplied by (*) the square root (v) of TJC] plus (+) [0.28 * v of SJC] + (0.70 * the natural logarithm (ln) ESR in millimeters per hour (mm/h)] + [0.014 * participant's global assessment of disease activity (GH)]. DAS28-ESR = 5.1 = high disease activity, DAS28-ESR less than or equal to (=) 3.2 = low disease activity, DAS28-ESR less than (<) 2.6 = remission.

Change in Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) Score From BL at Week 48 - FACIT-F scores were obtained from a 13 question self-administered participant questionnaire designed to measure the degree of fatigue experienced by participants in the previous 7 days. Participants responded to the questions using a value between 0 and 4, where 0 indicated "not at all" and 4 indicated "very much." 11 of the 13 questions were negatively stated; indicating the higher the score of the participant's response, the greater their fatigue. These questions were calculated as 4 minus the participants' response, so that a higher score indicated an improvement in health. The scores for the 2 positively stated questions were not changed. The participants' responses were summed to result in an overall score, which are scored 0 to 52 (52 = highest level of functioning). A positive change from BL indicated improvement.

Short-Form 36 Health Survey (SF-36) Score - SF-36 scores were obtained by scoring participants' responses to a 36 item questionnaire. SF-36 evaluated 8 aspects of functional health and well being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health from a range of 1 (better) to 5 (worst). The score for each section was an average of the individual question scores, which were scaled 0-100 (100=highest level of functioning). These 8 aspects were summarized as physical and mental component scores.

The change categories were defined for the change from BL to Weeks 24 and 48 according to this schema. Negative to borderline was defined as any change from negative to borderline as no dilution is given for negative results. Negative to positive was defined as at least a two-fold positive change in dilution from BL. Borderline to negative was defined as any change from borderline to negative as no dilution is given for negative results. Borderline to positive was defined as at least a two-fold positive change in dilution from BL. Positive to borderline was defined as at least a two-fold negative change in dilution from BL. Positive to negative was defined as at least a two-fold negative change in dilution from BL. Unchanged was defined as any difference in dilution less than two-fold.
