Filter by:This non-interventional, multinational study of topical field treatment of actinic keratosis (AK) aims to collect real-life experience with ingenol mebutate as well as one or two other topical field therapies commonly used in the individual country. Physicians will report baseline characteristics, while the main study focus will be on patient reported outcomes 3-4 weeks after treatment completion (treatment satisfaction, adherence, resource utilization and Health Related Quality of Life. Dermatology centres in Denmark, Norway, Sweden, the Netherlands, the United Kingdom and Canada will participate.
The objective of the trial is to investigate efficacy and safety of ingenol mebutate gel for actinic keratosis applied to large treatment areas once daily for three consecutive days on face, scalp or chest.
The objective of this study is to determine the efficacy, safety, and patient satisfaction of pretreatment with Picato® gel 4 days prior to methyl aminolevulinate photodynamic therapy (MAL PDT). Patients diagnosed with actinic keratosis who are eligible to receive topical treatment with ingenol mebutate (Picato®) and photodynamic therapy will act both as the test group and the control group. Each patient will have four distinct treatment areas of 25cm2 on the scalp, and/or scalp and face. Three of the treatment areas will receive Picato® 0.015% gel, MAL PDT, or Picato® 0.015% and MAL PDT combined. One area will serve as a control and will receive none of the treatments.
This is a phase 1 study to access the safety and tolerability of KX2-391 ointment in subjects who have Actinic Keratosis. This study will also access the amount of KX2-391 drug that enters the blood stream through dermal application of the ointment.
The objective of this study is to translate the "AKQoL"-questionnaire which measures the quality of life of patients with actinic keratosis into German and to validate it for the Swiss population. By using the technique of cognitive interviewing the investigators are focussing on the patients' understanding of the questions. The first session of cognitive interviews will show, where there is need for improvement in terms of misinterpreted phrases or vaguely worded questions. The goal is to rephrase the questions according to the feedback of the patients. The revised version will then be presented to a new population.
The objective of the trial is to investigate the Safety of LEO 43204 0.018%, 0.037% and 0.1% for actinic keratosis applied once daily for three consecutive days on face/chest, scalp and trunk/extremities, respectively.
The main purpose of this vehicle-controlled study is to determine the efficacy and safety of a solution of Actikerall® (containing 5-fluorouracil 0.5% and salicylic acid 10.0%) in the field-directed treatment of grade I-II actinic keratosis, when it is applied to the affected area once daily for 12 weeks. A secondary objective of this study is to evaluate the efficacy of Actikerall® solution on subclinical actinic keratosis lesions in a subset of patients.
A multi-centre randomised controled single blind clinical phase IV trial with the aim to determine the most effective treatment in terms of lesion reduction, costs and patient satisfaction in treatment of actinic keratosis (AK), when comparing topical treatment with photodynamic therapy (PDT), 5% 5-fluorouracil (5-FU) cream, 5% Imiquimod (IMI) cream and ingenol mebutate (IM) gel.
The purpose of this study is to evaluate the potential for systemic exposure of aminolevulinic acid (ALA) when applied topically under occlusion, in a maximal use setting in patients with multiple actinic keratoses (AK) involving the upper extremities.
Actinic keratosis (AKs) are premalignant disorders that can evolve into skin cancer. To prevent their development, a study is being conducted with oral isotretinoin and topical tretinoin to verify what drug is the most effective and has the best security profile for these patients. Along with these treatments, cryotherapy with liquid nitrogen and sunscreens will be part of the treatment. The study will have the duration of 10 months. In the first four months, the AKs will be counted and treated with cryotherapy (face and arms) and sunscreens FPS 60 will be used. After it, the patients will return (the AKs will be counted), a new session of cryotherapy will be performed and they will be randomized into two groups: one group using oral isotretinoin 10mg/day ( ISO: 30 patients) and the other one using tretinoin 0,05% cream (AR: 30 patients) applied on face and arms. Skin biopsies will be done for all 60 patients at the beginning of the treatment with retinoids (isotretinoin and tretinoin). After six months of treatment with retinoids, the study will be stopped, AKs will be counted again and skin biopsies will be done. Patients in the group ISO (oral isotretinoin) also have to make blood tests at the beginning, two months and after six months of the treatment. Clinical (AK counting), histological (improvement of parts of the skin) and immunohistochemical parameters will be evaluated to see what drug is more effective for prevention of AKs.
