Diabetes drug cream shows promise for psoriasis in new trial
NCT ID NCT07516821
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a cream made from metformin, a common diabetes drug, can safely improve mild psoriasis. About 55 adults will apply either the metformin cream or a placebo twice daily for two months. Researchers will check skin biopsies and symptom scores to see if the treatment reduces inflammation and itching.
