Study summary

This single-center interventional study was designed to evaluate the efficacy and safety of two CE-marked topical medical devices: PROXERA PSOMED 20 is being studied in participants with non-palmoplantar plaque psoriasis, while PROXERA PSOMED 40 is being studied in participants with non-pustular palmoplantar psoriasis.

The study aims to determine whether treating a target area with the assigned medical device leads to greater clinical improvement compared to the untreated contralateral control area in the same participant. For PROXERA PSOMED 20, the primary assessment is performed after 4 weeks of treatment. For PROXERA PSOMED 40, the primary assessment is performed after 8 weeks of treatment.

Secondary objectives include the assessment of safety, local tolerability, overall psoriasis progress, its impact on quality of life, and additional parameters of local disease activity at the target areas. Participants will apply the assigned study device once daily to the selected target area, undergo clinical assessments at scheduled visits, and provide safety and tolerability information throughout the study.

What researchers measure

Primary outcomes

  1. Difference Between Treated and Untreated Target Plaques in Change From Baseline in Target Lesion Score at Week 4

    The Target Lesion Score assesses the severity of a representative psoriatic plaque based on erythema, induration (thickness), and scaling. Each component is scored from 0 to 4, and the total score ranges from 0 to 12, with higher scores indicating greater lesion severity. In participants treated with PROXERA PSOMED 20, the outcome compares the change from baseline to Week 4 in the treated target plaque with the change in the contralateral untreated control plaque.

    Time frame: Baseline to Week 4 (end of treatment)

  2. Difference Between Treated and Untreated Target Areas in Change From Baseline in Local Modified Palmoplantar Psoriasis Area and Severity Index at Week 8

    The local modified Palmoplantar Psoriasis Area and Severity Index (mPPPASI) assesses erythema, induration, scaling, and extent of involvement in each target palm or sole area. Erythema, induration, and scaling are each scored from 0 to 4, while extent of involvement is scored from 0 to 6. For each target site, the local score is calculated as (erythema + induration + scaling) × extent and ranges from 0 to 72, with higher scores indicating more severe disease. In participants treated with PROXERA PSOMED 40, the primary analysis compares the change from baseline to Week 8 in the treated target area with the change in the contralateral untreated control area.

    Time frame: Baseline to Week 8 (end of treatment)

Secondary outcomes

  1. Difference Between Treated and Untreated Target Plaques in Change From Baseline in Target Lesion Score at Week 8

    The Target Lesion Score assesses the severity of a representative psoriatic plaque based on erythema, induration (thickness), and scaling. Each component is scored from 0 to 4, and the total score ranges from 0 to 12, with higher scores indicating greater lesion severity. In participants treated with PROXERA PSOMED 20, the outcome compares the change from baseline to Week 8 in the treated target plaque with the change in the contralateral untreated control plaque.

    Time frame: Baseline to Week 8 (4 weeks after the end of treatment)

  2. Difference Between Treated and Untreated Target Areas in Change From Baseline in Local Modified Palmoplantar Psoriasis Area and Severity Index at Week 12

    The local modified Palmoplantar Psoriasis Area and Severity Index (mPPPASI) assesses erythema, induration, scaling, and extent of involvement in each target palm or sole area. Erythema, induration, and scaling are each scored from 0 to 4, while extent of involvement is scored from 0 to 6. For each target site, the local score is calculated as (erythema + induration + scaling) × extent and ranges from 0 to 72, with higher scores indicating more severe disease. In participants treated with PROXERA PSOMED 40, the outcome compares the change from baseline to Week 12 in the treated target area with the change in the contralateral untreated control area.

    Time frame: Baseline to Week 12 (4 weeks after the end of treatment)

  3. Change From Baseline in Psoriasis Area and Severity Index Score at Week 4 in the PROXERA PSOMED 20 Cohort

    The Psoriasis Area and Severity Index (PASI) assesses overall psoriasis severity by combining the extent of body surface involvement with the severity of erythema, induration, and scaling across different body regions. The total PASI score ranges from 0 to 72, with higher scores indicating greater overall psoriasis severity. This outcome measures the change in PASI score from baseline to Week 4 in participants with non-palmoplantar plaque psoriasis treated with PROXERA PSOMED 20. The assessment is used to determine whether changes observed in the target plaque occur independently of, or in parallel with, changes in overall psoriasis severity.

    Time frame: Baseline to Week 4 (end of treatment)

  4. Change From Baseline in Psoriasis Area and Severity Index Score at Week 8 in the PROXERA PSOMED 40 Cohort

    The Psoriasis Area and Severity Index (PASI) assesses overall psoriasis severity by combining the extent of body surface involvement with the severity of erythema, induration, and scaling across different body regions.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 28, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
