Overview
Vitiligo is an autoimmune depigmentation disorder affecting 0.5 to 1% of the population worldwide. Vitiligo lesions are characterized by a progressive loss of pigmentation caused by the disappearance of functioning melanocytes in the epidermis, mainly resulting from the activation of immune cells in a genetically predisposed patient.
Despite major advances in the understanding of the mechanisms of the disease, the treatment remains challenging. Different treatment strategies could lead to cosmetically acceptable repigmentation (>75%), particularly on face and neck. However, after repigmentation, the risk of relapse is estimated at nearly 40% during the first year after stopping treatment.
To date, long-term management remains a challenge. With their topical product RV5098A adapted for patients with vitiligo, Pierre Fabre Laboratories hypothesize that it could be effective in maintaining pigmentation of previously repigmented lesions in adults with facial vitiligo.
