Efficacy of Topical Metformin in Psoriasis Vulgaris
Egypt55 participantsStarted 2026-04-01
Plain-language summary
The goal of this clinical trial is to learn if topical metformin works to treat mild psoriasis vulgaris. It will also learn about the safety of topical metformin. The main questions it aims to answer are:
Does topical metformin improve psoriatic plaques in early psoriasis? What medical problems do participants have when use topical metformin? Researchers will compare topical metformin to a placebo (a look-alike substance that contains no drug) to see if topical metformin works to treat psoriasis vulgaris.
Participants will:
put topical metformin or placebo twice daily for 2 months. Visit the clinic once every months for follow up. Keep a diary of their symptoms and any side effects.
Skin biopsy will be taken from psoriatic plaque before starting treatment and another one will be taken after 2 months of starting treatment to assess the level of IL-17.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Assessment and comparison of tissue levels of interleukin 17 (IL - 17) between the topical metformin and placebo group.
Timeframe: 8 weeks after starting treatment
2
Comparison of percent PASI improvement from baseline between the topical metformin and placebo groups.
