New pill shows promise for vitiligo in major trial
NCT ID NCT06113471
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a daily pill called povorcitinib to see if it can safely bring back skin color in people with nonsegmental vitiligo, a condition where white patches appear on the skin. About 450 adults will receive either the drug or a placebo for 52 weeks. The main goal is to measure at least a 75% improvement in facial skin color.
