Brief Summary:
The aim of the exploratory study is to compare dose related effects of LAS41004 formulations in a non-occlusive PPT.

Condition or disease Intervention/treatment Phase
Psoriasis Drug: LAS41004 Phase 2

Detailed Description:
Going for a non-occlusive application design will allow to draw practical conclusions as being similar to a real treatment situation (compared with a occluded design to maximise effects)

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 22 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A 22 Day Controlled, Randomized Clinical Study (PPT) Investigating the Anti-psoriatic Efficacy and the Tolerability of an Ointment Containing a Retinoid and a Steroid in Different Concentrations
Study Start Date : August 2011
Actual Primary Completion Date : September 2011
Actual Study Completion Date : September 2011

Primary Outcome Measures :
  1. Decrease of skin thickness(AUC, area under the curve) [ Time Frame: day 1 to day 22 ]
    Measurement of skin thickness will be performed by ultrasound (distance between lower border of entry echo and lower border of dermis). The area under the curve, AUC, from day 1 to day 22 will be compared to the reference formulations.


Secondary Outcome Measures :
  1. Decrease in scaling [ Time Frame: baseline vs day 22 ]
    scoring of scaling (score 0-4) will be performed by investigator

  2. decrease in erythema [ Time Frame: baseline vs day 22 ]
    scoring of erythema (score 0-4) wil be performed by investigator

  3. decrease of induration [ Time Frame: baseline vs day 22 ]
    scoring of induration (score 0-4) will be performed by investigator

  4. assessment of (s)AE [ Time Frame: from baseline to day 22 ]
    a daily record will be performed and if needed the severity and causality assessed
