Investigation With BiopH+Psoriasis Medical Bath in Subject With Mild to Moderate Plaque Psoriasis.

Study Overview
=================
Brief Summary
-----------------
The purpose of this investigation is to assess performance and safety of BIOpH+ Psoriasis Medical Bath in comparison to a comparative device.

Detailed Description
-----------------
After being informed about the investigation and the potential risks, all subjects giving written informed consent will undergo screening to determine eligibility for study entry. At week 0, subjects who meet the eligibility requirements will be randomised in open, intra-patient investigation, treated with BIOpH+ Psoriasis Medical Bath on one side, and comparative treatment on the other side for 8 weeks.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Psoriasis Area and Severity Index (PASI) score from Baseline compared to week 8. | The PASI score is a validated, investigator instrument assessing the severity of psoriasis. The severity is combined with the percentage of affected area. | Baseline and week 8. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dermatology Life Quality Index (DLQI) | A quality of life instrument and will evaluate how much the skin problems affects the study subject's daily life. It is a 10-question questionnaire. Each question contains four response categories: 0=not at all, 1=a little, 2=a lot, and 3=very much. A higher score means worse outcome. | Baseline and week 8. | 
| Psoriasis Area Severity Index (PASI) | It combines the severity (erythema, induration and desquamation) and percentage of affected area. A high score means worse outcome. The body is divided into 4 sections: Head, weight = 0.1 Arms, weight = 0.2 Trunk, weight = 0.3 Legs, weight = 0.4 For each section, the percent of area of skin involved is estimated and graded: 0. 0% of involved area <10% of involved area 10-29% of involved area 30-49% of involved area 50-69% of involved area 70-89% of involved area 90-100% of involved area Within each area, the severity is estimated for 3 clinical signs: erythema (redness), induration (thickness) and desquamation (scaling). Severity is measured on a scale from 0-4, from none to maximum. The sum of all 3 severity parameters is calculated for each body section, multiplied by the area score for that area, and multiplied for the weight of the body section, for a maximum score of 72. | Week 2 and week 4 | 
| Physician Global Assessment (PGA) | The Physician Global Assessment, is a 5-point scoring system that will be used to assess the overall disease severity. This treatment response on each visit will be scored: 0 =cleared, 1=almost clear, 2=mild 3=moderate, and 4=severe. A higher scores mean worse outcome. | Baseline, week 2, 4, and 8 | 
| Tolerability assessment | Tolerability assessment completed by the study subject about local tolerance regarding experience of pruritus and burning/stinging measured on a 5-point scale, or by questions to be answered with yes or no. | Week 2, 4 and week 8. | 
| Usability /satisfaction assessments | A questionnaire to be answered by study subject about investigational device usability and satisfaction measured on a 5-point scale, or by questions to be answered with yes or no. | Week 8 |
