The main objective of this study is to evaluate the long-term safety of CP-690,550 in patients being treated for moderate to severe chronic plaque psoriasis. This is an open label extension study available to patients who participated in one of the qualifying studies with CP-690,550 providing entry criteria is met.
The study terminated on 08MAR2016 as it met its objectives of characterizing long term safety and tolerability. The study did not terminate due to safety concerns.

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 4 weeks after last dose (up to 67 months) that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.
Time frame: Baseline up to 4 weeks after last dose of study drug (up to a maximum of 67 months)
Number of Adverse Events (AEs) by Severity
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs were classified according to the severity in 3 categories: a) mild: AEs did not interfere with participant's usual function; b) moderate: AEs interfered to some extent with participant's usual function; c) severe: AEs interfered significantly with participant's usual function.
Time frame: Baseline up to 4 weeks after last dose of study drug (up to a maximum of 67 months)

Percentage of Participants Achieving Physician Global Assessment (PGA) Response of 'Clear' or 'Almost Clear'
The PGA of psoriasis was scored on a 5-point scale, reflecting a global consideration of the erythema (E), induration (I), and scaling (S) across all psoriatic lesions in participants. The severity rating scores (Erythema: 0= no evidence of erythema to 4= dark, deep red; Induration: 0= no evidence of plaque elevation to 4= marked plaque elevation, hard/sharp borders; Scaling: 0= no evidence of scaling to 4= thick, coarse scale predominates) were summed (E + I + S = total) and the average (total/3) was taken. The total average was rounded to the nearest whole number score to determine the PGA. The 5-point scale for PGA was: 0= clear; 1= almost clear; 2= mild; 3= moderate; 4= severe, where higher score indicated more severity of psoriasis. Percentage of participants with response of 'clear' (score of '0') and 'almost clear' (score of '1') were reported.

Euro Quality of Life- 5-Dimensions (EQ-5D)-Utility Scores
EQ-5D: participant rated 5-dimension (mobility, self-care, usual activities, pain and discomfort, and anxiety and depression) questionnaire to assess health-related quality of life in terms of a single utility score. Each dimension was assessed on a 3-point scale (1=no problems, 2=some problems, 3=extreme problems, where higher scores=worse health condition). The responses from the 5 dimensions were used to calculate a single utility index value. Scoring formula developed by EuroQol Group assigned a utility value for each dimension in the profile. Score was transformed and results in a total score range -0.594 to 1.000; higher score indicated a better health state.

Number of Participants Who Answered Psoriasis Healthcare Resource Utilization Questionnaire (Ps-HCRU)
Ps-HCRU was a short questionnaire designed to assess healthcare resource use and the impact of psoriasis on work. In the first section, it assessed direct costs associated with healthcare resource use which included participant's interactions with healthcare providers such as general practitioners, dermatologists, cardiologists, gastroenterologists, psychiatrists, surgeons and nurses. When taking the evening dose of tofacitinib, participants were asked to answer the Ps-HCRU questionnaire only if they had an interaction with a healthcare provider or their work was impacted by psoriasis on that specified day. In this outcome measure, number of participants who answered Ps-HCRU at any specified visits were reported.
