View clinical trials related to Actinic Keratoses.
Filter by:This Phase III study is designed to evaluate the efficacy and safety of KX2-391 Ointment 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.
This study is a multicenter study investigating the clinical efficacy of repetitive daylight-PDT with MAL (Methylaminolevulinate) compared to cryosurgery in regard to prophylaxis and treatment of AKs (actinic keratoses) in the face. Patients will be randomly allocated to treatment groups. 5 PDT (photodynamic therapy) treatment sessions (visits 1-5) will be performed within 18 months. In the control group, cryosurgery will be performed at visit 1, and in case of non-cleared or newly occurred AKs at visits 2-5. In the PDT group the patients will apply a chemical sunscreen (SPF 50+) to the whole face and other light-exposed, unprotected areas of the skin. After at least 15 minutes a lesion preparation of AKs (removal of crusts) will be performed and MAL will be applied in a thin layer to the whole face. Within 30 min after MAL application patients expose themselves to daylight for 2 hours. In the control group, cryosurgery will be performed using liquid nitrogen spray in each AK lesion; this will be done at visit 1 and, if necessary, also at visits 2-5. At visits 2-6, the efficacy of the treatment will be evaluated by the observer by documenting all existing and newly appearing AKs in the face.
This is an investigator initiated, two center, randomized, evaluator-blinded, bilateral (right vs. left) study of photodynamic therapy in subjects with facial actinic keratoses. Subject's face will be randomized to receive one of four treatments: Treatment 1, Treatment 2, Treatment 3 or Treatment 4. Treatment 1 will include microneedling performed prior to ALA application to their right face and ALA application only to the left face 60 minutes prior to BLUE light treatment for 1000 seconds (16 minutes 40 seconds). Treatment 2 will include microneedling performed prior to ALA application to their left face and ALA application only to the right side of their face 60 minutes prior to BLUE light treatment for 1000 seconds (16 minutes 40 seconds). Treatment 3 will include microneedling performed prior to ALA application to their right face and ALA application only to the left side of their face 30 minutes prior to BLUE light treatment for 1000 seconds (16 minutes 40 seconds). Treatment 4 will include microneedling performed prior to ALA application to their left face and ALA application only to the right side of their face 30 minutes prior to BLUE light treatment for 1000 seconds (16 minutes 40 seconds). The face is defined as the surface of the skin encompassing the forehead to the hair line and tops of the eyebrows, the entire nasal dorsum, the cheeks (bounded by the orbital rim, the anterior border of the ear, the jawline, the nose and the chin), the upper lip (not including the vermilion border) and the chin (bounded by the lower edge of the vermilion border, the cheek junction and the jawline). The treatment areas will be not be occluded. A line will be drawn with a marker that intersects the nose, forehead, upper lip and chin in the midline. The left face is defined as the face to the left of this line and the right face is defined as the face to the right of this line. Posttreatment follow-up visits will be scheduled to occur 48 hours after the treatment and at 1, 3 and 6 months after the treatment. A blinded evaluator who will remain blinded with respect to the randomization will conduct grading of the subject's actinic keratoses and photodamage. Tolerability of treatment will be assessed by evaluations of the local skin response (erythema, edema, etc.) and will be conducted by an unblinded evaluator. Safety will be evaluated by adverse events and local skin responses reported during the study
Photodynamic therapy (PDT) uses visible light to treat a premalignant condition, called actinic keratosis, which results on chronically sun exposed skin such as on a balding scalp. A cream is applied containing aminolaevulinic acid or methyl aminolaevulinate and this is converted in the cells to the photodegradable product protoporphyrin IX (PpIX). Visible light causes the degradation of PpIX resulting in the production of reactive oxygen species and then cell death in the actinic keratosis. In conventional PDT a lamp is used to supply the visible light. The main draw back to treatment is pain. Recent studies have shown that daylight can be used as the source of visible light and is as effective as conventional PDT. Patients find this form of treatment less painful and therefore preferable. The reduction in pain seen in daylight PDT appears to be related to the fact that no significant quantity of PpIX accumulates prior to exposure to the light source and small quantities of PpIX are activated continuously during daylight exposure. The drawback of performing daylight PDT in Ireland is the climate, both in terms of cloud cover and temperature. The typical daylight treatment times is 2 hours and it would be difficult for patients to stay outside in winter, spring and autumn. This study investigates the use of an artificial white light source, a Maquet PWD 50SF theatre-light, as an alternative.
A double-blind, placebo controlled study conducted at a single study site. Evaluating the role of systemic antihistamine therapy in the reduction of adverse effects associated with topical 5-aminolevulinic acid photodynamic therapy.
Actinic keratoses (AK) are common cutaneous lesions associate with chronic ultraviolet radiation exposure. While most authorities consider AK as a pre-malignant lesion, some consider it as an incipient squamous cell carcinoma (SCC). Ingenol mebutate is the active compound in the sap from Euphorbia peplus L. (E. peplus). Topical ingenol mebutate treatment has been approved for the treatment of AKs. Ingenol mebutate gel 0.015% has shown to not only have a high clearance rate but also a transient localized inflammatory skin response that resolves quickly without sequelae. However, these localized skin responses (eg erythema, erosion/ulceration, edema, etc.) can often be unpleasant and unsightly. Currently, there are no clinical studies evaluating combination therapies (eg topical steroids, emollients) with ingenol mebutate 0.015% that would decrease irritation and improve wound healing while maintaining efficacy.
The main objective of this study is to compare efficacy and safety of Metvix® natural daylight photodynamic therapy with those of Metvix® conventional photodynamic therapy in subjects with mild actinic keratoses (intra-individual comparison)
The primary aim of this study is to evaluate the effects of prospective patient education on patient satisfaction with administration of topical 5% 5-fluorouracil cream for the treatment of actinic keratosis involving the face, scalp, upper chest, dorsal hands and forearms. Specifically, this study aims to determine if prospective patient viewing of an educational video delineating treatment effects and expectations improves patient satisfaction and treatment completion rates.
