Study Overview
=================
Brief Summary
-----------------
This was a randomized, double blind,fixed dose, placebo controlled, parallel-group pilot study to obtain data on size and variance of treatment effects in subjects with mild to moderate Psoriasis.

Detailed Description
-----------------
This was a randomized, double blind,fixed dose, placebo controlled, parallel-group pilot study to obtain data on size and variance of treatment effects in subjects with mild to moderate Psoriasis. The target sample size of 60 was selected as a practical figure for recruitment purposes in one centre over 3 months.After a 2 week washout during which only emollients were applied to their psoriasis, patients attended for baseline assessment of psoriasis severity and blood tests.Subjects attended every 4 weeks for 12 weeks for clinical assessment and blood tests.Each patient once eligible{see inclusion & exclusion criteria} was allocated to either active treatment or placebo in identical packing for a total of 12 weeks.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Psoriasis area and severity index between baseline and end of feeding | The PASI score stands for Psoriasis Area and Severity Index. This tool allows researchers to put an objective number on what would otherwise be a very subjective idea: how bad is a person's psoriasis. To make up the score, the three features of a psoriatic plaque (redness) scaling and thickness are each assigned a number from 0 to 4 with 4 being worst. Then the extent of involvement of each region of the body is scored from 0 to 6. Adding up the scores give a range of 0 to 72 | At 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Psoriasis Disability Index[PDI} | The Psoriasis Disability Index questionnaire is designed for use in adults, i.e. patients over the age of 16. It is self explanatory and can be handed to the patient who is asked to fill it in without the need for a detailed explanation. It is usually completed in three or four minutes. There are two possible alternative formats of the PDI. One uses visual analogue scales for each answer, the other uses tick box choices for each answer | at 12 weeks |
