Controlled Study of Humira in Subjects With Chronic Plaque Psoriasis of the Hands and/or Feet

Number of subjects achieving a PGA of clear (representing no signs of plaque psoriasis) or almost clear (representing just perceptible erythema and scaling) at Week 16. The PGA is a 5-point scale used to measure the severity of disease at the time of the physician's evaluation of the subject. The degree of overall severity is rated as follows: 0-Clear, 1-Almost clear, 2-Mild, 3-Moderate, and 4-Severe.

Severity of each sign of ESIF was assessed using a 4-point scale (0 = clear, 1 = mild, 2 = moderate, and 3 = severe). The ESIF was calculated by adding the scores for the 4 signs for the two soles and two palms, for a total range from 0 (no disease) to 48 points (most severe condition). A decrease from Baseline in ESIF indicates improvement.

Severity of each sign of ESIF was assessed using a 4-point scale (0 = clear, 1 = mild, 2 = moderate, and 3 = severe). The ESIF was calculated by adding the scores for the 4 signs for the palms of the hands, yielding a total range from 0 (no disease) to 24 points (most severe condition) for the palms. A decrease from Baseline in ESIF indicates improvement.

Number of subjects that achieved > 50% reduction from Baseline in ESIF.

Number of subjects that achieved > 75% reduction from Baseline in ESIF

For subjects with psoriasis nail involvement at Baseline, the target fingernail (most severely involved fingernail at Baseline) was assessed for NAPSI throughout the study. NAPSI ranges from 0 (no nail psoriasis) to 8 (most severe nail psoriasis).

Number of subjects achieving a PGA of clear (representing no signs of plaque psoriasis), almost clear (representing just perceptible erythema and scaling), or mild (representing light pink erythema with minimal scaling and with or without pustules). The PGA is a 5-point scale used to measure the severity of disease at the time of the physician's evaluation of the subject. The degree of overall severity is rated as follows: 0-Clear, 1-Almost clear, 2-Mild, 3-Moderate, and 4-Severe.

Number of subjects who achieved 50% or greater improvement from baseline PASI. The PASI scale is from 0 (no psoriasis) to 72 (complete erythroderma of the severest possible degree).

Number of subjects who achieved 75% or greater improvement from baseline PASI. The PASI scale is from 0 (no psoriasis) to 72 (complete erythroderma of the severest possible degree).

Number of subjects who achieved 90% or greater improvement from baseline PASI. The PASI scale is from 0 (no psoriasis) to 72 (complete erythroderma of the severest possible degree).

Number of subjects who achieved 100% improvement from baseline PASI. The PASI scale is from 0 (no psoriasis) to 72 (complete erythroderma of the severest possible degree).

The DLQI consists of 10 questions and is scored from 0 (total lack of impairment) to 30 (life is very much impaired). A decrease in DLQI indicates improvement.

Number of subjects achieving a DLQI score of 0, indicating total lack of impairment. The DLQI consists of 10 questions and is scored from 0 to 30 (life is very much impaired). A decrease in DLQI indicates improvement.

On one single VAS, subjects assessed their pain due to psoriasis (and psoriatic arthritis, if applicable). Mean change in psoriasis and psoriatic arthritis pain from Baseline as measured by a VAS from 0 (no pain) to 100 (pain as bad as it could be).

WPAI:PSO assesses the effect on the subject's ability to work and perform regular activities in 4 areas: % work time (in hours) missed due to psoriasis, % impairment while working (on a scale from 0 [psoriasis having no effect] to 10 [psoriasis completely prevented subject from working]), % overall work impairment (on a scale from 0 [psoriasis having no effect] to 10 [psoriasis completely prevented subject from working]), and % activity impairment (on a scale from 0 [psoriasis having no effect on daily activities] to 10 [psoriasis completely prevented subject from doing daily activities]).

The PHQ-9 consists of 9 questions that assess how often over the past 2 weeks subjects had signs or symptoms of depression (0=not at all, 1=several days, 2=more than half days, and 3=nearly every day). The PHQ-9 is the sum of the scores from the 9 questions for a total range from 0 (not depressed at all) to 27 (depressed nearly every day).

Based on the 9 questions of the PHQ-9, if subjects indicated any problems (PHQ-9 score > 0), the difficulty to do work, take care of things at home, and get along with people (question 10 of the PHQ) were assessed (not difficult at all, somewhat difficult, very difficult, and extremely difficult).
