Can a hormone drug help restore skin color in vitiligo?
NCT ID NCT07437560
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 study tests whether adding Melanotan II (a synthetic hormone-like drug) to standard narrowband UV-B light therapy helps restore skin color in adults with stable nonsegmental vitiligo. About 60 participants will receive either the drug or a placebo, plus light therapy, for several months. Researchers will measure changes in skin pigmentation and track how quickly repigmentation occurs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Melanotan II (a synthetic hormone-like drug) plus narrowband UV-B phototherapy
- What this could lead to
- If it works, this could offer a new treatment option to restore skin color in people with stable vitiligo.
- What could go wrong
- This is an early Phase 2 trial with only 60 participants, so results may not apply to everyone. The drug may cause side effects or not improve repigmentation more than light therapy alone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18-65 years able to provide informed consent. * Clinical diagnosis of nonsegmental vitiligo with stable disease (no new lesions and no lesion expansion) for \>=6 months prior to screening. * Total body surface area involvement between 3% and 20% (inclusive), with at least two measurable target lesions suitable for standardized photography and colorimetry. * Willingness to undergo NB-UVB phototherapy per protocol and to avoid non-study vitiligo treatments during the study. * For participants of childbearing potential: agreement to use effective contraception during the study and for a protocol-specified period after the last dose. Exclusion Criteria: * Segmental vitiligo as the predominant type, or rapidly progressive disease within the past 6 months. * Use of systemic immunosuppressive therapy, systemic corticosteroids, or JAK inhibitors within 8 weeks prior to screening (time windows may vary by drug/class). * Use of topical calcineurin inhibitors or topical corticosteroids on target lesions within 2 weeks prior to baseline. * Prior treatment with afamelanotide or melanotan (including Melanotan II) within 6 months prior to baseline. * History of melanoma, dysplastic nevus syndrome, or other high-risk skin cancer history requiring close surveillance, as judged by the investigator. * Clinically significant uncontrolled hypertension, cardiovascular disease, or any condition that, in the investigator's judgment, increases risk with melanocortin agonist exposure. * Pregnant or breastfeeding. * Known hypersensitivity to study product components. * Participation in another interventional clinical trial within 30 days prior to screening.
