Maintenance Treatment of Non Segmental Vitiligo With Tacrolimus Ointment 0.1% Versus Control

Tacrolimus ointment 0.1% has shown promising results for treating vitiligo in many prospective studies. Prospective randomized studies versus placebo are required to confirm the hypothesis that maintenance treatment with two applications of tacrolimus ointment 0.1% per week can reduce relapses of non-segmental vitiligo lesions. Main objective To assess the efficacy of maintenance therapy with topical tacrolimus vs placebo in the prevention of depigmentation in patients with vitiligo who responded to treatment. Secondary objectives * Evaluate the efficacy of maintenance therapy with tacrolimus vs topical placebo to decrease the intensity of depigmentation in patients with vitiligo who responded to treatment. * To study the occurrence of possible adverse effects. Length of the study Inclusion: 12 months Treatment: 6 months Follow-up: 6 months Total length of the study: 18 months Intervention Multicentric prospective interventional randomized comparative study versus placebo. * Visit V0: Selection Information of the patient, control of inclusion and non inclusion criteria. * Visit V1: Control of inclusion and non inclusion criteria, patients signed informed consent. An initial clinical evaluation and photographs in direct sunlight and UV. Topical treatment (tacrolimus or placebo) will be delivered to the patient by the hospital pharmacy and should be applied twice per week (3 or 4 days apart) for 24 weeks. * Visit V2: The patient will be reviewed after the end of treatment (24 weeks after the visit V1) for final evaluation. A clinical assessment will be made and photographs in the same way as the inclusion. Adverse reactions during treatment will be collected by the investigator (they will be noted as and when the patient in a notebook that will be presented at baseline). The percentage of depigmentation will be evaluated in a blinded treatment of photographs by two reviewers. In case of disagreement, the opinion of a third appraiser will be required. \- End o
