Arm Description

Participants will need to have two separate clinically healed psoriasis plaques. At baseline (visit 2), one target lesion (plaque # 1) will be actively treated with once-daily cutaneous application of Enstilar® foam and one target lesion (plaque # 2) will be treated with placebo-vehicle. Participants will then simultaneously be treated three-weekly with full-body NB-UVB for 8 weeks (or a minimum of 20 sessions in total). After 4 weeks of Enstilar® and emollient, treatment application will be changed to twice-weekly until EOT (visit 5). First dose of IMP will be administered by trained personal. Subsequent doses will be administered by the participant. Study visits will occur at Screening, Baseline (Week 0), Weeks 8, 13, and 18. At baseline, week 8, week 13, and week 18 two skin punch biopsies will be acquired from each target lesion.

Placebo-vehicle will be given as explained for the arm description under Enstilar.

Evaluate the efficacy of Enstilar® foam in combination with NB-UVB on changing the Psoriasis Area and Severity Index.
Change between baseline, week 8, week 13, and week 18 for Psoriasis Area and Severity Index (PASI). PASI is the most widely used tool for assessing psoriasis severity in clinical trials. PASI is calculated as a measure of the average redness, thickness, and scaliness of the lesions (each graded on a 0-4 scale, with 0 being none and 4 being maximum), weighted by the involved body surface area in percentage. Results range from 0 to 72 with 0 being no disease and 72 being complete skin coverage with 4 in redness, 4 in thickness, and 4 in scaliness. Treatment response is assessed as PASI reduction in percentage. Every effort should be made to ensure that assessments will be performed by the same investigator at all visits including screening.
Evaluate the efficacy of Enstilar® foam in combination with NB-UVB on changing the 5-point Investigator's Global Assessment.
Change between baseline, week 8, week 13, and week 18 for the 5-point Investigator's Global Assessment (IGA). The IGA is a static psoriasis severity assessment tool consisting of a 5-point ordinal scale ranging from ''clear'' to ''severe''. Every effort should be made to ensure that assessments will be performed by the same investigator at all visits including screening.
Evaluate the efficacy of Enstilar® foam in combination with NB-UVB on changing the Target Plaque Severity Score.
Change between baseline, week 8, week 13, and week 18 for the Target Plaque Severity Score (TPSS). The TPSS is used in this study to bilaterally compare the treatment effect in localized psoriasis target plaques. The TPSS includes a measure of the redness, thickness, and scaliness of the lesion and is graded on a 0 to 4 scale (0 = clear, 1 = slight, 2 = mild, 3 = moderate, 4 = severe). The scores will be summed to produce the TPSS sum score. Furthermore, standardized target lesion images and subsequent computerized image analysis will be used to calculate the Target Plaque Area (TPA). Every effort should be made to ensure that assessments will be performed by the same investigator at all visits including screening.
Evaluate the efficacy of Enstilar® foam in combination with NB-UVB on changing the Dermatology Life Quality Index
Change between baseline, week 8, week 13, and week 18 for the Dermatology Life Quality Index (DLQI). The DLQI is one of the most used validated questionnaires to assess the quality of life (QoL) associated with dermatological conditions. 10 items address the participant's perception of the impact of their skin disease on different aspects of their quality of life (QoL). Each item is scored on a 4-point Likert scale (0 = not at all/not relevant; 1 = a little, 2 = a lot, 3 = very much). The total score is the sum of the 10 items (0 to 30). A high score is indicative of a poor QoL. A 4-point change in the DLQI total score is normally referred to as a within-participant minimal important difference. A DLQI total absolute score of 0 or 1 indicates no or small impact of the disease on health related quality of life.

5. Study Description

Brief Summary
Psoriasis is a non-communicable chronic immune-mediated disease. Psoriatic skin is characterized by excessive proliferation of skin cells and infiltration of immune cells. The cause of psoriasis is so far unknown. Established therapeutics include topical, oral-systemic, biologic, narrow-band ultraviolet B (NB-UVB). A persistent antipsoriatic effect by the newest biologic therapies has been demonstrated after treatment discontinuation. However, the remittive hallmark of psoriasis suggests the existence of a molecular scar, a kind of disease memory, in clinically healed skin. It has been suggested that this disease memory can be attributed to the tissue-resident memory T (TRM) cell. The main purpose of the study is to investigate whether (NB-UVB) treatment and concomitant Enstilar® treatment can change the amount of TRMs in the skin as well as change the expression in the microenvironment around these cells in the skin from psoriasis patients. In addition, the investigators will investigate whether the treatment can change the quantity and types of other psoriasis-related cells in the skin. In addition to this, the investigators will also examine the effect of treatment on patient-related parameters.
