A Phase 3, Multi Site, Randomized, Double Blind, Placebo Controlled Study Of The Efficacy And Safety Comparing CP- 690,550 And Etanercept In Subjects With Moderate To Severe Chronic Plaque Psoriasis

The PGA of psoriasis is scored on a 5-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling are scored separately over the whole body according to a 5-point severity scale (0 to 4). The severity scores are summed and averaged after which the total average is rounded to the nearest whole number score to determine the PGA score and category (0=clear; 1=almost clear; 2=mild; 3=moderate; and 4=severe). PGA response was defined as 0 (clear) or 1 (almost clear).

The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of body surface area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk [including axillae and groin], and lower limbs [including buttocks), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI75 response was defined as at least a 75 percent (%) reduction in PASI relative to baseline/Day 1.

Combined assessment of lesion severity and area affected into single score; range=0(no disease)-72(maximal disease). Body divided into 4 sections=head, upper/lower limbs, trunk; each area scored by itself and scores combined for final PASI. For each section percent area of skin involved was estimated:0(0%)-6(90-100%) and severity estimated by clinical signs of erythema, induration, scaling; ranged 0-4: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked. Final PASI=sum of severity parameters for each section*area score*weighing factor (head=0.1, upper limbs=0.2, trunk=0.3, lower limbs=0.4). PASI score can vary in increments of 0.1; higher scores represent greater severity of psoriasis.

Assessment of BSA with psoriasis performed separately for 4 body regions: head and neck, upper limbs, trunk (including axillae and groin), and lower limbs (including buttocks). The % surface area with psoriasis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. The number of handprints of psoriatic skin in a body region was used to determine the extent (%) to which a body region was involved with psoriasis.

The DLQI is a general dermatology questionnaire that consists of 10 items that assess health related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). The DLQI questions are rated by the participant as 0 (not at all/not relevant) to 3 (very much) with a total score range of 0 (best) to 30 (worst); higher scores indicate poor quality of life.

The SF-36 is a general health status questionnaire that assesses 8 domains of functional health and well being: Physical Functioning, Role Limitations due to Physical Health Problems, Bodily Pain, Social Functioning, Mental Health, Role Limitations due to Emotional Problems, Vitality, and General Health Perceptions. The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). A PCS score and MCS score are based on a normalized sum of the 8 scale scores; PCS/MCS summary concept score = (raw score*10) plus 50. Higher scores indicate a better health related quality of life.

EQ-5D: participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state.

The Psoriasis Health Care Resource Utilization (Ps-HCRU) questionnaire is a short questionnaire designed to assess healthcare resource use and the impact of psoriasis on work. The first section assesses direct costs associated with healthcare resource use (interactions with healthcare providers such as general practitioners [GPs], primary care physicians [PCPs], or family medicine physicians [FMP], emergency room visits, and hospitalizations), and the second section assesses indirect costs associated with absenteeism due to psoriasis and the impact of psoriasis on productivity at work.

Psoriasis Health Care Resource Utilization Questionnaire is a short questionnaire designed to assess healthcare resource use and the impact of psoriasis on work. The questionnaire assesses employment status of participant (employed: yes or no) and if currently employed it asks the participant if they were absent or on sick leave from work due to psoriasis; if unemployed it asks the participant if the unemployment is due to psoriasis.

The PQOL-12 is a 12-item questionnaire; 8 of the items on the Koo-Menter Psoriasis Index 12-item Quality of Life Questionnaire (PQOL-12) focus on emotional issues associated with psoriasis (self conscious, helpless, embarrassed, ability to enjoy life). The last 4 items deal with physical symptoms (pain or soreness, itch, physical irritation) and choice of clothing. The recall period is over the past month. The questions are answered on a scale from 0 to 10 with 0 being best and 10 being worst. Scores from each question are summed to give a total score (range 0 -120); higher scores indicate greater impairment to quality of life.
