Filter by:Photodynamic therapy is an effective treatment for actinic keratoses. In the United States topical aminolevulinic acid (ALA) is approved as a photosensitizing agent for this treatment, and it has traditionally been activated with the use of an in-office artificial light source. This clinical trial seeks to measure the safety and efficacy of using natural sunlight to activate the ALA.
Er:YAG ablative fractional laser-assisted photodynamic therapy (AFL-PDT) has shown significant benefit for the treatment of actinic keratosis(AK). Er:YAG ablative fractional laser ablates the epidermis and dermis without significant thermal injury, creating microscopic ablation zones (MAZ) in the portion of the skin that the laser is applied to. The formed MAZ depends on the laser parameters such as laser depth, laser density and laser passes, which affect the treatment outcome.
This is a randomized, single-blind controlled trial with parallel group design to determine whether daylight photodynamic therapy (PDT) affords a reduction in treatment symptoms of pain, burning, and pruritus as measured by 1) symptom level during the treatment period and 2) pain at the end of treatment exposure.
The purpose of this research is to obtain a blood sample from patients with actinic keratoses undergoing routine Photodynamic Therapy, in order to measure biomarkers that are relevant to VitD and 5FU metabolism and might be predictive of PDT outcome. The biomarkers to be examined include serum VitD levels at the time of PDT, and the presence/absence of gene alleles that correlate with expression of several proteins involved in VitD and 5FU metabolism. The presence of these biomarkers will be correlated to the improvement in AK lesion counts at the patient's routine follow-up visit 3 months after PDT treatment.
This study will evaluate the safety and effectiveness of Shade for the management of UV-induced skin complications and data collected from this study will be used to support the proposed indications for use.
This Phase III study was designed to evaluate the efficacy and safety of KX2-391 Ointment 1% in adult participants when applied to an area of skin containing 4-8 stable, clinically typical actinic keratosis (AK) lesions on the face or scalp.

This proposed project will be an open-label, split face, randomized controlled pilot study. Up to 60 patients with diffuse facial actinic keratosis will be enrolled in the study. The purpose of this study is to understand the change in skin appearance throughout 5-FU treatment course and to examine whether a topical corticosteroid and moisturizer can decrease severity and duration of skin inflammation after 5-FU treatment course.
The study investigates if a computer-based clinical decision support tool for skin cancer may improve the diagnostic accuracy of general practitioners (GPs). The aim of the program is to help GPs increase their diagnostic accuracy, in particular regarding the selection of suspicious skin lesions that need biopsy or referral to specialist health care for further assessment. Half of the physicians in the trial will have the clinical decision support tool available during consultations, while the other half has no such tool available. We hypothesize that general practitioners using the clinical decision support tool will have a higher number of correct classifications of skin lesions compared to doctors without the tool.
The purpose of this study is to demonstrate the safety, tolerability and efficacy of AO+ Mist administered daily for 4 weeks to improve the appearance of skin afflicted with keratosis pilaris.
