Study Details

Study Description

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
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)

  • Outcome Measures

    Primary Outcome Measures

    1. Decrease of skin thickness(AUC, area under the curve) [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 [baseline vs day 22]

      scoring of scaling (score 0-4) will be performed by investigator

    2. decrease in erythema [baseline vs day 22]

      scoring of erythema (score 0-4) wil be performed by investigator

    3. decrease of induration [baseline vs day 22]

      scoring of induration (score 0-4) will be performed by investigator

    4. assessment of (s)AE [from baseline to day 22]

      a daily record will be performed and if needed the severity and causality assessed

    Eligibility Criteria

    Criteria

    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • 18 to 75 years of age

    • Caucasian men and women

    • Suffering from mild to moderate plaque psoriasis of at least 6 months duration that is amenable to local therapy

    • With at least one stable psoriatic plaque in an area sufficient for product application meeting the following criteria:

    1. located at trunk and/or extremities (plaques located on the head, palms, or sole of feet, intertriginous or genitoanal areas are not suitable)

    2. Where more than one plaque is to be used, plaques that are comparable, with at least "2" in each score for scaling, erythema and induration.

    3. No more than 3 points difference in total score (sum of scores for scaling, erythema and induration)

    4. Negative urine pregnancy test (in female patients of child bearing potential)

    • In the case of women of childbearing potential, using reliable methods of contraception which result in a low failure rate i.e. less than 1% per year (eg contraceptive implants or injectables, combined oral contraceptives, some intrauterine devices, sexual abstinence or vasectomized partner)
    Exclusion Criteria:
