Study summary

To assess whether adding fractional laser to topical corticosteroid improves treatment outcomes in palmoplanter psoriasis compared to topical corticosteroid alone.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    fractional carbon dioxide (CO₂) laser-assisted delivery of topical corticosteroids

    fractional carbon dioxide (CO₂) laser-assisted delivery of topical corticosteroids will be done on palmoplantar psoriasis every 4 weeks

    Device: Fractional CO2 laser assisted drug delivery

  • Active comparator
    Topical corticosteroids alone

    Application of topical corticosteroid alone in patients with palmoplantar psoriasis daily.

    Drug: Topical Corticosteroid (TCS)

Interventions

  • DeviceFractional CO2 laser assisted drug delivery

    Sessions of fractional CO2 every 4 weeks with application of topical steroids

    Also known as: fractional CO2 laser

  • Daily application of topical corticosteroids on palmoplantar psoriasis

    Also known as: Topical steroids

What researchers measure

Primary outcomes

  1. Improvement in Palmoplantar Psoriasis Severity Index (ppPASI) by topical corticosteroids only vs fractional CO₂ laser-assisted delivery of topical corticosteroids

    The primary outcome will be the change in the Palmoplantar Psoriasis Severity Index (ppPASI) score from baseline to the end of treatment (at Week 12). The ppPASI assesses disease severity based on erythema, scaling, and induration/infiltration of the palms and soles, in addition to the affected surface area. Scores range from 0 to 72, with higher scores indicating more severe disease. Treatment success: Achievement of ppPASI-50, ppPASI-75, and ppPASI-90 (≥50%, ≥75%, and ≥90% reduction from baseline).

    Time frame: 3 month

Secondary outcomes

  1. Physician Global Assessment (PGA)

    Clinical improvement will be assessed using the Physician Global Assessment for palmoplantar psoriasis. The PGA is a 5- or 6-point scale: 0 = Clear 1. = Almost clear 2. = Mild 3. = Moderate 4. = Severe 5. = Very severe (if using the 6-point scale)

    Time frame: 3 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Feb 2027, 6 months later.

Of 75 non-industry phase 4 interventional studies under Psoriasis, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 49. This study's planned 6 months is below that.

Counting every sponsor, half of 115 studies reached it within 23 months; a quarter within 12 and three quarters within 43.

How these figures are worked out, and which studies are left out of them.

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 20, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
