Filter by: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.
This is a multicenter clinical trial, phase III, randomized, placebo-controlled, parallel group, enroll 94 patients, to assess the efficacy of ACH24 in the repigmentation of achromatic areas in patients with vitiligo.
The study is an on-line survey posted on survey monkey that addresses some demographic and environmental issues that could potentially relate to vitiligo vulgaris onset or disease exacerbation.
The purpose of this study is to determine whether afamelanotide and narrow band UVB are effective in the treatment of non-segmental vitiligo (NSV).
Rationale: Punch grafting is a safe, simple and widely used technique for in vitiligo. However, no reliable data are available on the effect of punch depth and punch size. Objectives: Primary: to compare the efficacy and safety of different punchdepths and punchsizes in punch grafting in patients with segmental and non-segmental vitiligo. Secondary: to assess the practical aspects and patients preference of different punch grafting techniques. Study design: Prospective observer blinded randomised controlled study. Study population: 35 patients ≥ 18 years with segmental or stable non-segmental vitiligo who will receive regular treatment by punch grafting at the Netherlands Institute for Pigment Disorders (SNIP) at the Academic Medical Centre University of Amsterdam. Methods: Four depigmented regions on the trunk or upper extremities will be randomly allocated to either epidermal 1,5 mm punch grafting, epidermal 1mm punch grafting, dermal 1,5 mm punch grafting and dermal 1 mm punch grafting. After grafting, all regions will receive UV-therapy twice a week for 3 months. Three and six months after grafting, the repigmentation of the lesions will be assessed by measuring the outgrowth. Main study parameter/endpoint: Outgrowth of pigment after six months. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The study involves 16 additional punch grafts but no additional visits to our institute. Patients will not miss any regular treatment. The extra time due to participation in the study will be about 40 minutes. No increase of the risk of side effects is expected by placing 16 additional punch grafts. 1.
Vitiligo has remained a difficult disease to treat. Previous available therapies are often ineffective. It usually takes several months or years for complete repigmentation and some areas of the body get at best only partial repigmentation. The desire of the patient to undergo therapy varies from patient to patient and needs to be assessed individually. Several factors should be considered when planning the treatment strategies including type of vitiligo, site and degree of involvement, skin color, psychological effect, patient compliance, ease to assess to therapy, cost of treatment and social association of the disease. Topical corticosteroids are still be the standard treatment of localized vitiligo. However, the adverse effects such as skin atrophy, striae, pigmentary change and hypothalamic-pituitary adrenal axis suppression can occur if we use inappropriate strength of topical steroids for a long period of time. Tacrolimus (FK-506) is a new immunosuppressive agent that acts by inhibiting T-cell activation and cytokine release. It offers a safe and efficacious alternative for many skin conditions. It minimizes the need for topical glucocorticoids and does not cause skin atrophy. Tacrolimus was first reported for treatment of vitiligo in 2002. The underlying mechanism was shown in an in vitro study that topical tacrolimus promoted proliferation of melanocytes and melanoblasts. This study purpose is to evaluate the efficacy and safety of 0.1% topical tacrolimus ointment comparing to 0.1% mometasone furoate cream in the treatment of adult vitiligo.
This study evaluates micrografting using a harvesting and grafting process that has been designed by Momelan Technologies. The overall concept is to harvest several small pieces of skin, each measuring about 1.75 mm in diameter from a normal pigmented area using a commercially available suction blister device, adhere them to a sterile elastomeric substrate and is then place it on a recipient area prepared by epidermal dermabrasion (removal of the epidermis).
The purpose of this study is the evaluate the efficacy of using a low-energy 635 nm visible light laser in the treatment of various recalcitrant forms of vitiligo.
Rationale: Vitiligo vulgaris is a common acquired pigment disorder, which is characterised by the development of depigmented macules. It develops probably due to immunedestruction of melanocytes. Most effective therapies are immunsuppresive: 1. local immunesuppressives like corticosteroids and calcineurin inhibitors 2. phototherapy like PUVA and NB-UVB phototherapy. NB-UVB is the first choice A synergistic effect of UVA and topical corticosteroids (fluticasone proprionate 0.05% cream) has been described by Westerhof et al. in 1999. To our knowledge to date there are no publications comparing NB-UVB combined with a topical corticosteroid and NB-UVB alone. Objective: The objective of this study is to evaluate the clinical effects (onset and degree of repigmentation) of fluticasone proprionate 0.05% cream (thrice weekly) on NB-UVB phototherapy twice weekly for a period of 12 months. Study design: Prospective single blinded randomised controlled study. Study population: Consecutive patients ≥ 18 years, diagnosed with active vitiligo vulgaris who will receive NB-UVB phototherapeutic treatment at the Netherlands Institute for Pigment Disorders at the Academic Medical Centre (AMC), University of Amsterdam. Methods: The patient will be randomised for either NB-UVB phototherapy and fluticasone proprionate 0.05% cream or NB-UVB phototherapy alone for 12 consecutive months. Main study parameters/endpoints: The onset and degree of repigmentation is assessed by digital image analysis of a target lesion and blinded global physician assessment. Furthermore, the patients and doctors satisfaction will be assessed and changes of immunohistochemical parameters will be analysed in skin biopsies. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Subjects participating in the study will be asked to visit the institute 4 times. The time investment will be 20 minutes per visit. Additionally, patients will be asked for consent to take punch biopsies (3 mm) at the beginning and at the end of the treatment period. Hence, skin biopsies are not compulsory for participation in this study. Patients may chose to participate in the clinical non invasive part of the study. Known side effects of the NB-UVB phototherapy are redness, pruritus, xerosis cutis, burning sensation and conjunctivitis. These side-effects however, are largely dose-dependent and avoidable. Corticosteroid associated systemic side-effects (suppression of the adrenocortex) will be minimized by treating only a limited body surface [a maximum of 30% body surface] and by using an intermittent application scheme of three days a week in the long term treatment. The regions which are known to have a higher absorption are excluded (periorbital, axillary, inguinal and genital area). Both topical corticosteroids and NB-UVB are part of the Dutch and British guidelines for the treatment of vitiligo. There is no presumptive evidence or indication that the combination of these therapies may result in a higher risk of side effects. All together the burden due to the study is low and the risk for systemic or local side effects is low.
Vitiligo vulgaris is an autoimmune disorder that causes loss of pigmentation over the skin, hair and mucous membranes (e.g. lips, nose, genitals). While genes have been identified that are thought to be required for development of vitiligo, only 5-10% of relatives develop disease. The triggers for disease onset have not yet been identified. The intent of this study is to research trends in laboratory data, social and medical history that may be contributory to vitiligo onset, location of disease, course of illness and response to therapy.
