Afamelanotide and Narrow-Band Ultraviolet B (NB-UVB) Light in the Treatment of Nonsegmental Vitiligo (NSV) (CUV102)

March 21, 2013 updated by: Clinuvel Pharmaceuticals Limited

Proof of Concept Study to Compare Efficacy and Safety of Subcutaneous, Bioresorbable Afamelanotide Implants and Narrow-Band Ultraviolet B (NB-UVB) Light Versus NB-UVB Light Alone in the Treatment of Nonsegmental Vitiligo

The purpose of this study is to look at the efficacy of afamelanotide, when combined with narrow-band ultraviolet B (NB-UVB) light, in patients with nonsegmental vitiligo. Afamelanotide is expected to speed up the repigmentation induced by NB-UVB light, leading to reducing frequency and doses of NB-UVB.

Detailed Description

Vitiligo is the most common depigmentation disorder. Interventions in the treatment of vitiligo include phototherapy with narrow-band (NB) ultraviolet B (UVB) irradiation (NB-UVB). Further therapeutic approaches are desired and currently being evaluated. The investigational product, afamelanotide, is a synthetic analogue of the human alpha melanocyte stimulating hormone (alpha-MSH). The earliest described function of alpha-MSH is its ability to stimulate melanin synthesis in the skin and therefore stimulate pigmentation.
