There are many treatment modalities available for vitiligo, however, none of them cure the disease. Ultraviolet A1 (UVA1) phototherapy has been shown to be useful for a variety of skin diseases. However, there are only a few studies published on the efficacy of UVA1 in vitiligo. This is a prospective single-blind randomized clinical trial to assess efficacy and safety of UVA1 in the treatment of vitiligo.', 'detailedDescription': 'Vitiligo is a chronic acquired disease characterized by well defined white macules and patches affecting the skin and mucous membranes. Mucocutaneous lesions develop secondary to selective destruction of melanocytes. The etiology of vitiligo is largely unknown but more likely to be multifactorial. There are several theories on the pathogenesis of vitiligo including mainly the autoimmune, neurohormonal, and autocytotoxic theories. The autoimmune hypothesis has the strongest evidence with alteration mainly in the cellular immune response.\n\nThere are many treatment modalities available for vitiligo, however, none of them cure the disease. These include different topical treatments, phototherapy, surgical therapy, and depigmentation therapy. Narrow-band UVB (NB-UVB) is currently the preferred treatment over topical psoralen and ultraviolet A radiation (PUVA), for patients with vitiligo. However, overall response of vitiligo to NB-UVB has been variable. Ultraviolet A1(UVA1) phototherapy is now useful for a variety of skin diseases, specifically scleroderma. There are only a few studies published on the efficacy of UVA1 in vitiligo.\n\nOne of the main side effects of UVA1 is prominent tanning which might be due to melanocyte stimulation. Therefore, the investigators hypothesis is that UVA1 will induce significant skin pigmentation to improve vitiligo. The investigators plan on conducting a prospective single-blind randomized clinical trial to assess efficacy and safety of UVA1 in the treatment of vitiligo.\n\nStudy Objectives\n\n1. To evaluate the potential for UVA1 to induce repigmentation within vitiligo patches.\n2. To assess the side effect profile of UVA1 when used in the treatment of vitiligo.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '19 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age \\> 18 years.\n* Localized or generalized vitiligo that involves a non mucosal or acral site.\n* Patients should have a patch of at least 25 cm2 that shows no more than 10% repigmentation as assessed visually\n\nExclusion Criteria:\n\n* Patients who received treatment for vitiligo within the past 3 weeks.\n* Patients known to have a photosensitivity disorder\n* History of previous skin cancer.\n* History of severe medical illness or immunosuppression.\n* Pregnancy or breast-feeding.'}, 'identificationModule': {'nctId': 'NCT01787695', 'briefTitle': 'UVA 1 Phototherapy for Vitiligo', 'organization': {'class': 'OTHER', 'fullName': 'University of British Columbia'}, 'orgStudyIdInfo': {'id': 'H10-02235'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'No treatment (covered)'}, {'type': 'ACTIVE_COMPARATOR', 'label': 'UVA1', 'interventionNames': ['Procedure: UVA1']}], 'interventions': [{'name': 'UVA1', 'type': 'PROCEDURE', 'description': 'Patients with a vitiligo patch larger than 25cm2 will be recruited.
