Clinical Trials

Melanotan II is currently being evaluated in a clinical trial to determine its therapeutic potential in dermatological conditions characterized by cutaneous depigmentation. Specifically, research focuses on nonsegmental vitiligo, including stable nonsegmental vitiligo, to evaluate the peptide as an adjunctive treatment with narrow-band phototherapy. Sponsored by Hudson Biotech, this Phase 2 study (NCT07437560) is actively recruiting participants to evaluate safety, tolerability, and repigmentation efficacy. Overall, this clinical effort seeks to clarify the role of synthetic melanocortin receptor agonism in restoring epidermal melanin in patients with vitiligo.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Melanotan II acts as a synthetic cyclic analog of alpha-melanocyte stimulating hormone that binds to and activates melanocortin receptors, driving downstream cyclic AMP signaling to promote melanogenesis and cellular melanin production in melanocytes. This activation enhances skin pigmentation and melanocyte survival, providing a physiological basis for promoting epidermal repigmentation in dermatological disorders such as nonsegmental vitiligo.
