Single dose psoriasis study
Brief summary
The purpose of this research study is to evaluate the safety and tolerability of ILV-095 when it is given to individuals with moderate to severe chronic plaque psoriasis. Another purpose of the study is to observe how the drug enters the blood and tissues over time, how the body breaks down the drug and whether or not the body will develop an immune reaction (sensitivity) to the drug.
Detailed description
B1991002 study is a phase 1 adaptive design study which terminated on 14Mar2011. Regular analyzes of psoriasis assessments conducted per the statistical plan indicate that even if every patient enrolled for the rest of the study respond (up to 23 additional subjects), the study can not meet its primary efficacy endpoint. Pfizer Inc. has terminated the trial and clinical team is asking all clinical investigators to continue collecting safety, pharmacokinetics and pharmacodynamics data until the last subject last visit for all subjects who received test article. Last Subject Last Visit occurred 20May2011.

BMI is calculated by taking the subject's weight, in kilograms, divided by the square of the subject's height, in meters, at screening: BMI = weight (kg)/(height \[m\]). * Must meet the following criteria for disease activity, at screening and/or at study entry (subjects who washout from prior therapy may not meet this level of disease activity at screening but must before being entered into the study). * Must have stable moderate to severe chronic plaque psoriasis covering \>=15% of body surface area and be a candidate for systemic therapy or phototherapy. * Psoriasis Area Severity Index (PASI) score of \>11. * Physician Global Assessment (PGA) of psoriasis score \>=3. * Target lesion score \>=6 based on the physician rating of selected sites for erythema, plaque elevation and scaling, with a minimum of 2 on the plaque elevation score. A-12-point score will be used with a 1-4 scale for each domain. Target lesions should not be on the scalp, axillae, face, or groin.
Exclusion criteria
* Presence or history of any disorder that may prevent the successful completion of the study. * Evidence of unstable clinically significant disease (eg, unstable cardiovascular, renal, respiratory, or psychiatric disease or any serious disorder that currently requires physician care). * Acute disease state (eg, nausea, vomiting, fever, or diarrhea) within 7 days before study day 1. * Evidence of skin conditions (eg, eczema) other than psoriasis that would interfere with evaluations of the effect of study medication on psoriasis. * Presence of guttate, erythrodermic, or pustular psoriasis. * Active severe infections within 4 weeks before study day 1. * Systemic malignancy within the past 5 years including melanoma. Treated skin cancer (basal cell carcinoma or squamous cell carcinoma) is excluded. Evidence of latent tuberculosis by purified protein derivative (PPD) screening. PPD screening should be performed according to local standards using the tuberculin skin test (TST). Any result \>5mm is considered positive. Prior Bacillus Calmette-Guerin (BCG) should not be taken into account when interpreting a TST result. TST must be performed during the screening period unless one has been performed within the previous 3 months and the results are available.

Physician Global Assessment (PGA) Score of Psoriasis
PGA of psoriasis was scored on a 5-point scale, reflecting a global consideration of the erythema (E), infiltration (I), and scaling (S) across all psoriatic lesions. The severity rating scores (erythema: 0= no evidence of erythema to 4= dark, deep red; infiltration: 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 score divided by 3) was calculated. The average was rounded to the nearest whole number score to determine the PGA. The 5-point scale for PGA was ranging from: 0= clear; 1= almost clear; 2= mild; 3= moderate; 4= severe, where higher scores indicated more severity.
