Measure Type Primary
Measure Title Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Month 3
Measure Description HAQ-DI: participant-reported assessment of ability to perform tasks in 8 functional categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3, 0=least functional difficulty and 3=extreme functional difficulty.

Measure Title Percentage of Participant With Disease Activity Score Using 28-Joint Count and Erythrocyte Sedimentation Rate (4 Variables) (DAS28-4 [ESR]) Less Than 2.6 at Month 3
Measure Description DAS28-4 (ESR) calculated from swollen joint count (SJC) and tender/painful joint count (TJC) using 28 joint count, erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and patient's global assessment (PtGA) of disease activity (transformed score ranging 0 to 10; higher score indicated greater affectation due to disease activity). Total score range:0 to 9.4, higher score indicated more disease activity. DAS28-4 (ESR) less than or equal to (=<) 3.2 implied low disease activity, greater than (>) 3.2 to 5.1 implied moderate to high disease activity and less than (<) 2.6=remission.

Measure Type Secondary
Measure Title Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale at Baseline and Month 3
Measure Description FACIT-Fatigue is a 13-item questionnaire. Participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the 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 participant'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 reflected an improvement in the participant's health status.

33.  Secondary:   Work Productivity and Healthcare Resource Utilization (HCRU) at Month 6   [ Time Frame: Month 6 ]

Measure Type Secondary
Measure Title Work Productivity and Healthcare Resource Utilization (HCRU) at Month 6
Measure Description Rheumatoid Arthritis (RA)-HCRU assessed healthcare usage during last 3 months for direct, indirect medical cost domains. Direct cost:visit to doctor,non-medical practitioner,nursing home,hospital,surgery,emergency room(ER) treatment,diagnostic tests, over-night stay,home healthcare services, aids/devices used. Indirect costs associated with functional disability:employment status,willingness to work,work disability due to RA,sick leave,part time work,ability to perform chores,chores done by family/friends/housekeeper. Assessment was based on 0 to 2-point scale;higher score=higher medical cost.
Time Frame Month 6

44.  Other Pre-specified:   Time to First Greater Than 1 Day Sequential Decrease in Pain From Baseline for Patient Assessment of Arthritis Pain   [ Time Frame: 2 weeks ]

Measure Type Other Pre-specified
Measure Title Time to First Greater Than 1 Day Sequential Decrease in Pain From Baseline for Patient Assessment of Arthritis Pain
Measure Description Participants assessed the severity of their arthritis pain using a 100 millimeter (mm) visual analog scale (VAS). The scale ranged from 0 (no pain) to 100 (most severe pain), measurement on a scale corresponds to the magnitude of their pain.
Time Frame 2 weeks  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
FAS: all participants who were randomized to study, received at least 1 dose of study drug (CP-690550/placebo), had at least 1 post-baseline measurement, and baseline measurement for change from baseline endpoint. ‘N’ (number of participants analyzed) signifies those participants who were evaluable for this measure.

Reporting Groups
  Description
CP-690,550 5 mg CP-690,550 5 milligram (mg) tablet orally twice daily up to Month 6.
CP-690,550 10 mg CP-690,550 10 mg tablet orally twice daily up to Month 6.
Placebo Matching placebo tablet orally twice daily up to Month 3.

Measure Type Other Pre-specified
Measure Title Time to First Greater Than 1 Day Sequential Decrease in Pain From Baseline for Patient Global Assessment of Arthritis
Measure Description 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.
Time Frame 2 weeks
