Active clinical trials for "Vitiligo"

The treatment of vitiligo remains disappointing especially in some localization such as bony prominences and extremities. The association of UVB and topical steroids has been proven to be synergistic but the results are still insufficient in those difficult to treat areas. Promising results have been shown with the combination of laser assisted dermabrasion, topical 5FU and UVB. The investigators hypothesize that the dermabrasion of vitiligo skin followed by topical steroids should potentialized the effect of UVB and be superior to topical steroids and UVB without dermabrasion. The main objective of this study is to evaluate the usefulness of laser assisted dermabrasion combined to topical steroids and UVB phototherapy in difficult to treat areas. Patients with symmetrical non segmental vitiligo will be included in this prospective randomized monocentrer study. The investigators calculated the number of patients needed at 25. The side that will receive the dermabrasion will be centrally randomized and the opposite side will serve as control. Then on both side class 3 topical steroids will be applied daily 3 weeks on 4 for 12 weeks. UVB phototherapy will be performed twice weekly also for 12 weeks. The evaluation will be performed by two independent physician blinded to the treatment of standardized photos before and 1 month after the end of the treatment. The criteria of success will be at least 75% of repigmentation.

The effect of treatment with narrow-band UVB 311 nm after transplantation of harvested autologous epidermal cells on vitiligo lesions will be investigated.

Patients with vitiligo vulgaris are treated with Pimecrolimus twice a day during 6 months. After a baseline visit, patient returns for a control visit after 3 and 6 months of treatment. One reference lesion is clinically evaluated with pictures.

Photoacoustic imaging (PAI) is an emerging method which combines light and ultrasound to assess the blood content and oxygenation of the body. Light is absorbed by the blood, leading to the generation of ultrasound, from which the levels of oxygen can be derived. This high sensitivity to blood has seen it applied in multiple clinical trials for the assessment of a number of conditions including breast cancer assessment. However, the accuracy of the measurements and image quality is known to decrease as you look deeper into the body because light intensity decreases. Melanin in the skin is known to absorb light very strongly and so there is considerable concern that this may bias measurements made in people with darker skin tones compared to those with lighter skin tones. In this pilot study, we intend to recruit volunteers with a wide range of skin tones and vitiligo. We will scan a number of blood vessels and muscles using PAI and evaluate the photoacoustic measurements of blood content and oxygenation to identify, and ultimately correct for, biases in advance of further clinical studies.

This work aims to assess sensory symptoms in early active vitiligo patients (segmental, non-segmental, or mixed) and to measure 3 neuropeptides expression in their lesional skin [neuropeptide Y(NPY), calcitonin gene-related peptide (CGRP), and nerve growth factors (NGF)] to correlate neuropeptide levels, sensory symptoms, and functions, with criteria of disease activity and perceived stress scale.

Multicentric French parallel double-blind randomized versus placebo study

The purpose of this study is to assess the efficacy of autologous epidermal cells suspension grafting using a newly developed device named VITICELL® compared to placebo. The secondary objective is to evaluate safety of VITICELL® and global satisfaction of patient and investigator.

Vitiligo is a depigmenting skin disease common. Vitiligo is caused by the disappearance of melanocytes in the epidermis. Vitiligo is the cause of disfigurement, psychological and social, that sounds a lot about the quality of life. Currently the standard treatment for vitiligo is ultraviolet ray (UV), but it only allows a 50% repigmentation of lesions in half of patients. The applications of autologous epidermal cells in the liquid phase is a promising new therapeutic approach of vitiligo. The main goal of this study is to compare prospectively the repigmentation of vitiligo lesions induced by application of autologous epidermal cells in liquid phase associated with light therapy and light therapy alone. Study's secondary goals: compare the applications of epidermal cells to phototherapy alone and phototherapy, in respect of: Obtain a repigmentation> 70% (threshold considered aesthetically relevant) The occurrence of adverse events Patient satisfaction regarding the efficacy and safety of treatment

Vitiligo is a chronic acquired cutaneous disease of pigmentation that affects patients' quality of life across all degrees of involvement and severity. Phototherapy, such as Narrow band UVB (NB-UVB), is a clinically indicated treatment for skin lesions. NB-UVB treatment has been shown to promote repigmentation and normalize cellular behaviors. The investigators would like to analyze the change in protein expression and histological change in skin from NB-UVB treatment in participants with Vitiligo. The investigators are recruiting participants with Vitiligo on the body, arms, and/or legs.

Vitiligo is a depigmentation disorder affecting 0.5 to 2% of the general population. It is an acquired pigmentary disorder of the skin and mucous membranes that is characterized by circumscribed, depigmented macules and patches. Apremilast is a phosphosdiesterase 4 (PDE4) inhibitor that showed efficacy and very good tolerance in rheumatoid arthritis and psoriasis. Apremilast induces a potent activation of the cyclic AMP (cAMP) pathway leading to anti-inflammatory effect by decreasing the response of Th1 and Th17 lymphocytes. Interestingly, the cAMP pathway is also well demonstrated to be the main pathway for promoting melanogenesis and for inducing the differentiation and the proliferation of melanocytes. The principal aims is to compare, after 24 weeks of treatment, the efficacy of Apremilast at the label dosage in combination therapy with narrow band UVB versus placebo therapy with narrow band UVB for repigmentation in patients with non-segmental vitiligo. Patients with non-segmental vitiligo with BSA > 10% and patient with Vitiligo stable or slowly progressive for 3 months , seeking for treatment in the Department of Dermatology, University Hospital of Nice, France will be recruited into the study. The Patients are seen in consultation by the investigator, selection criteria are checked. All patients will receive full body narrow UVB treatment, twice weekly sessions of narrow UVB for 24 weeks. From W24 to W48 All responders* will receive narrow UVB treatment according the French clinical use i.e.twice weekly sessions of narrowband UVB for 24 weeks. All responders* will be randomized to receive either apremilast** 30mg BID or placebo. Response is defined as an increase of at least 30 % in the VASI score at W24 compare to baseline **Responders initially randomized in the placebo arm will benefit of the titration At week 24, the non responders patients will stop the treatment and the study after the 4 weeks observationnal follow-up (W28). Observational Follow-up Phase - W48 to W52 Four-week Observational Follow-up Phase for all subjects who complete the study (responders and non responders) or discontinue the study early.
