Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Key Inclusion Criteria:

  • Male or female patients between 18 and 75 years of age with a diagnosis of stable plaque-type psoriasis (psoriasis vulgaris) for at least 12 months
  • Psoriatic plaques that are suitable to be defined as target area lesions by the following criteria:

oPsoriatic plaques must be located on the trunk and/or extremities. Plaques that are located on the head (incl. scalp), palms, sole of the feet, intertriginous or genitoanal areas are not suitable as target areas

  • Comparable psoriatic plaques with at least "2" in each score (range 0-4) for the three distinct signs: scaling, erythema and induration
  • No more than 3 points difference in total score (= sum of scores for scaling, erythema and induration; Range 0-12) of the chosen comparable psoriatic plaques
  • Enough surface area to the psoriatic plaque to define eight clearly distinguishable (minimum distance between test areas: 1cm) test areas of at least 1 cm² size - Effective contraceptive methods for the duration of the study and for the 4 weeks after study drug discontinuation, for a patient of childbearing potential.

Key Exclusion Criteria:

  • Too small a body surface area covered with psoriasis plaques that meet the specified inclusion criteria
  • Any condition that may interfere with the study assessments or ultrasound measurements of the skin and/or may have an influence on the skin immune response (incl. open wounds)
  • Current diagnosis of guttate, erythrodermic or pustular psoriasis
  • Patients who have received any topical anti-psoriatic drug in the test area within the last 2 weeks before treatment with the IMP.
  • Patients who have received topical products in the test area containing DEET (N,N-diethyl-m-polyamide), a common component of insect repellent products within 1 week before treatment with the IMP.
  • Patients who have received systemic biologics within the last 6 months before treatment with the IMP or any systemic antipsoriatic treatment (corticosteroids, ciclosporin, methotrexate, fumaric acid esters, acitretin etc)within the last 3 months before treatment with the IMP.
  • Significant skin diseases other than plaque-type psoriasis (psoriasis vulgaris), including but not limited to: skin disease due to tuberculosis or syphilis, rosacea, perioral dermatitis, acne vulgaris, skin atrophy, striae distensae, increased fragility of skin blood vessels, ichthyosis, ulcers, wounds and reaction after vaccination
  • Significant skin infections (including but not limited to: herpes, varicella, mycotic skin infections, bacterial skin infections or parasitic skin infections)
  • Excessive sunlight exposure within 28 days prior to study entry and during the conduct of the study
  • Usage of any topical formulation (incl. cosmetics, emollients, etc) on the designated target areas during the course of the study
  • Vitamin A intake > 15,000 IU/day

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Decrease in thickness of infiltration
Time Frame: Day 1 (baseline) vs day 15 day (final)
measurement will be performed by ultrasound, comparing data from baseline (day1) vs end of trial (day15)
Day 1 (baseline) vs day 15 day (final)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in clinical score
Time Frame: day 1 (baseline) vs day 15 (final)
scoring of total symptom score (0 - 12)will be performed by investigator, comparing data from baseline (day1) vs end of trial (day15)
day 1 (baseline) vs day 15 (final)
Change in erythema score
Time Frame: day1 (baseline) vs day 15 (final)
scoring of erythema (0-4) will be performed by investigator, comparing data from baseline (day1) vs end of trial (day15)
day1 (baseline) vs day 15 (final)
Change in Induration score
Time Frame: day 1 (baseline) vs day 15 (final)
scoring of induration (0-4) will be performed by investigator, comparing data from baseline (day1) vs end of trial (day15)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
