Filter by: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 study evaluate the efficacy and safety of ingenol mebutate gel 0.015% on face and scalp & 0.05% on trunk and extremities in Korean patient with actinic keratosis.
Prospective non-interventional study conducted in Australia, Brazil, Mexico and Europe to evaluate clinical practice with Metvix Daylight PDT in the treatment of mild to moderate actinic keratosis of the face/scalp and to assess physician and patient satisfaction.
Iontophoresis is a transdermal drug-delivery technique that enhances the transport of ionic species across membranes and may have significant benefit for the treatment of actinic keratosis (AK) by ablative fractional laser-primed photodynamic therapy (AFL-PDT).
This is an open-label safety study. During this study, the investigator will identify 4 eligible SK Target Lesions on each subject on the trunk, extremities and face.
This is a randomized, double-blind, vehicle-controlled, parallel group study.
This is a randomized, double-blind, vehicle-controlled, parallel group study of A-101 Solution 40% compared with Vehicle Solution.
The objective of this study was to evaluate the safety and therapeutic equivalence of generic ingenol mebutate gel, 0.05% to Picato gel, 0.05% and to establish the superiority of the efficacy of these two products over the vehicle gel in the treatment of Actinic Keratosis (AK) on the trunk or extremities.
The purpose of this study is to see how well DFD-07 works in treating actinic keratosis on the face and scalp during 8 weeks of treatment. The study will also look at any unwanted effects of the study drug.
This is a randomized, single-center, controlled, within-subject comparison study assessing the sensitization potential of the investigational product, LEO 43204 gel under open conditions in healthy volunteers. LEO 43204 Gel and Vehicle Gel will be applied to adjacent sites on the infrascapular area of the back. Evaluation of dermal reactions at the application sites will be assessed clinically using a visual scale that rates the degree of erythema, edema and other signs of cutaneous irritation. Following induction, subjects will have a 10 to 14-day Rest Phase, after which they will enter the Challenge Phase, which consists of one 48-hour application to a naive site on the opposite side of the back. Observations at the naive site during Challenge and the patterns of reactivity during the Induction Phase will provide a basis for an interpretation of contact sensitization. A total of 10 applications will be made over a period of approximately 6-8 weeks.
