Filter by:The purpose of the study is to evaluate the efficacy and safety of tirbanibulin 10 milligrams per gram (mg/g) ointment when applied to a treatment field (TF) larger than 25 centimeter square (cm^2) and up to 100 cm^2 in adult participants with actinic keratosis (AK).
The objective of the trial is to evaluate the safety and efficacy of SM-020 gel 1.0% in subjects with Seborrheic Keratosis (SK) compared to vehicle gel. It is a randomized, double-blind, vehicle-controlled trial. Approximately 60 subjects will be enrolled. Subjects will apply their assigned investigational product twice daily for 4 consecutive weeks. Subjects will be followed for 12-weeks post final application for a total of approximately 16-weeks of required participation in the study.
Reflectance confocal microscopy (RCM) is the reference in vivo imaging technique for identifying malignant melanocytic tumors prior to surgical excision. However, it is not widely used due to its high cost and highly technical and time-consuming nature. In addition to RCM, we currently use 2 less expensive dermatoscopes that also allow in vivo diagnosis: super-high magnification dermoscopy (D400) and Fluorescence-Advanced videodermatoscopy (FAV).
This prospective study aims to evaluate the responsiveness of the validated investigator global assessment (IGA) and composite area index score for keratosis pilaris by data collection through treatment and scoring sessions held at a private practice and relevant statistical analysis.
The goal of this clinical trial is to see if shorter Photodynamic Therapy (PDT) treatment times will still be effective at treating actinic keratoses (AK) while reducing or eliminating the pain that patients sometimes experience during conventional PDT treatment. The main questions it aims to answer are: - Will the application of the nanoemulsion (10% ALA gel), in the absence of occlusion, still achieve significant inflammation and lesion clearance? - Will shortened incubation times of Ameluz still achieve significant inflammation and lesion clearance? - Will the new test regimens achieve reduced pain during illumination? - Will the new test regimens be safe? Participants will be randomly assigned to one of three treatment regimens, which will determine the length of time that the topical medication will incubate on the face before red light exposure in PDT treatments. The incubation period will be either 10 minutes, 20 minutes, or 60 minutes.
Interventional, monocentric, national, internal placebo-controlled, prospective pilot study, consisting of two parts, A (single-blinded) and B (open) to assess Efficacy of Tirbanibulin for the treatment of AK on the back of the hand. In part A, eligible subjects receive Tirbanibulin on the left hand and placebo on the right hand for 5 d in a single-blinded manner. Safety and efficacy are assessed at day 8 (± 1 d) (3 days after the end of treatment (EoT+3) and day 57 (± 7 d) after the start of the treatment. Pictures will be taken at baseline, 8 d and 57 d (± 7 d) as per protocol and optional during unscheduled visits.
The increasing incidence of actinic keratosis (AK), morbus Bowen (MB) and cutaneous squamous cell carcinoma (cSCC), the patients with often multiple lesions and the disadvantages of invasive diagnostics show the need for an accurate non-invasive diagnostic tool for the determination of invasive growth in AK and MB. Optical coherence tomography (OCT) is a non-invasive scanner creating cross-sectional images of the skin, to a depth of 1-1,5 mm based on light waves. Until now, OCT has been proposed as non-invasive diagnostic tool for basal cell carcinomas. Although the diagnostic value of OCT for detection and sub-typing of basal cell carcinomas has already been demonstrated, it is unclear whether OCT can discriminate between invasive and non-invasive lesions (AK, MB and cSCCs). There are some studies that describe OCT characteristics of AK, MB and cSCCs, however, these characteristics have a lot of overlap (8-13). To date there are no clearly distinctive OCT features to distinguish between AK, MB and cSCCs. This study aims to investigate the value of OCT in discriminating between the presence and absence of invasion in lesions with clinical suspicion for invasion. Two experienced OCT-assessors will evaluate the OCT scans independently. The OCT assessors are blinded to the histological diagnosis of the lesions (invasive or non-invasive), which is used as golden standard. A 5-point Likert scale is used for OCT assessment. 1. Definitely not invasive 2. Probably not invasive 3. Unknown, probably invasive/probably not invasive 4. Probably invasive 5. Definitely invasive In addition to completing the Likert-scale, assessors are asked to describe the presence/absence of predefined OCT characteristics (a.o. hyperkeratosis and the presence of the dermo-epidermal junction) In case of disagreement between the independent assessors, the OCT scan will be re-assessed in a consensus meeting.
This study evaluates whether a Patient Decision Aid for the field-directed treatment of actinic keratosis has an effect on shared decision making and patient satisfaction.
The evaluation on the diagnostic accuracy of actinic keratosis recognition by general practitioners before and after participation on an e-learning program.
This study evaluates the implementation of the General Practitioners guidelines 'Suspicious Skin Lesions' and investigated whether their publication and implementation has led to a reduction in the proportion of referrals of low-risk patients with actinic keratosis to secondary care, after publication of the General Practitioners guidelines and implementation activities.
