Cream shows promise for genital vitiligo in early trial
NCT ID NCT05750823
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tested a cream called ruxolitinib (Opzelura) on 49 people with nonsegmental vitiligo affecting the genitals. Participants applied the cream twice daily for up to 48 weeks to see if it made the white patches less noticeable. The study measured success based on patient reports of how noticeable the vitiligo was compared to before treatment.
