Melanocyte Transplantation for Patients With Stable Vitiligo.
Phase I-II, Randomized, Intraindividually Placebo Controlled Clinical Trial, to Evaluate the Efficacy of Autologous Melanocyte Transplantion on Amniotic Membrane as a Substrate for Patients With Stable Vitiligo.
Vitiligo is an acquired skin disease that significantly impacts the quality of life of patients. Medical treatment of vitiligo includes the use of melanocyte transplantation but the results are variable.
This single center, single blind clinical trial comparing another treatment and also no treatment was designed to assess the efficacy of autologous monocyte transplantation in monolayers on a substrate of amniotic membrane for the treatment of stable vitiligo. Patients will receive the two interventions, melanocyte suspension and monolayer on amniotic membrane and will provide an untreated area as a control.
Study Overview
Detailed Description
Main Objective:
The main objective is to assess the efficacy of autologous transplantation of monocytes in monolayers grown on a biological substrate of amniotic membrane in the treatment of stable vitiligo. Using a system of digital imaging analysis the percentage of re-pigmentation obtained will be studied after 3, 6 and 9 months of treatment.
Secondary Objectives:
To demonstrate differences in efficacy (as measured by the percentage of re-pigmentation) of each of the 2 techniques used: pure melanocytes in suspension and amniotic membrane with melanocytes in monolayers.
To assess how rapidly epithelialization occurs and the cosmetic result in the short and long term of the areas treated with each of the techniques.
To assess if de-epidermization with CO2 laser may be by itself a stimulus for the reservoir of melanocytes in the adjacent epidermis or hair follicles or if the re-pigmentation obtained with this procedure is merely postinflammatory as a result of trauma to the epidermis.
