Summary: Earliest Stage Treatment of Actinic Keratosis with Imiquimod 3.75% Cream:The study is to demonstrate that Aktinic Keratosis are present before they are clinically visible, i.e. in a subclinical stage. Since on the basis of the research situation, also subclinical AK can proliferate into the dermis, it is possible that with the application of Imiquimod on chronically light-exposed skin, undetected ...

Summary: The study is a basic science research study that is designed to characterize and compare the immune response in individuals who are designated as ABO blood group secretors, meaning they have a functional copy of the FUT2 gene versus those patients who are designated ABO non-secretors after application of topical imiquimod to these patients.

Summary: Actinic cheilitis is a condition of the lower lip characterized by grayish-white areas of discoloration and blunting of the demarcation between the cutaneous lip and the mucosa.While many studies have compared treatment options for actinic cheilitis, there is still significant debate over how to best manage this condition. The chosen treatment regimen must result in complete remission while also p...

Summary: Transient local skin reactions with topical Actinic Keratosis treatments such as 5-FluoroUracil (5-FU) often lead to non-adhesion from patients and thus to treatment failure. In regards to 5-FU treatment, these local reactions are related to the pharmacological action of the molecule. The current therapeutic challenge is to reduce the local reactions induced by 5-FU without interfering with its ef...

Summary: Squamous cell carcinomas (SCC) are the second most common skin cancer in humans. The incidence of SCCs in the USA in 2012 was estimated at 700,000 casesSCCs have a metastatic course in 3% to 5% of cases that is of poor prognosis. In men, the SCCs of the scalp represent the most frequent location of the head and neck, the 3rd location of the whole body. The SCCs of the scalp are more undifferentiat...

Summary: The KOHDIAK study is a prospective, three-armed, randomised, double-blind study to evaluate the efficacy and safety of the treatment of mild and moderate actinic keratosis with a 5% potassium hydroxide solution (Solcera, medical device) versus placebo and investigator-blinded comparison with 3% diclofenac gel (Solaraze, medicinal product). It is performed in accordance with both the laws in force ...

Summary: Rationale: Keratinocyte skin cancer is known to influence the HRQoL in a specific way. Derived utility values are required for cost-effectiveness analyses of new interventions. However there is no sensitive tool to capture HRQoL that translates into utilities available.Objective: To document the exact HRQoL in patients with in KC using the generic EQ-5D-5L questionnaire, as well as the TTO, 15D an...

Summary: This study is being done to compare a new, continuous illumination and short Incubation time regimen of aminolevulinic acid photodynamic therapy#ALA-PDT) to a conventional regimen for treatment of Actinic Keratosis. The hypothesis is that the continuous illumination approach will be less or even no painful, but equally efficacious, as the old regimen.

Summary: Skin carcinomas are the most frequent cancers in the world, including basal cell carcinomas and cutaneous squamous cell carcinoma (cSCCs), with more than 60.000 new annual cases in France. Their incidence increases mainly due to ultraviolet (UV) exposure and population ageing. Then from 1994 to 2006, the incidence of cSCC has increased by 300%. CSCCs typically manifests as a spectrum from a precur...

Summary: A phase IV study of a single topical application of ALA for 3 hours or 4 hours to AK on acral sites (hands, feet, arms and legs), and subsequent measurement of clinical efficacy with corresponding PpIX fluorescence imaging.

Summary: The purpose of this clinical study is to evaluate if the DermaSense prototype EIS scanner can provide medical decision support which can complement dermoscopy-based identification of the disease at time of biopsy decision.

Summary: This study is designed as a double-blinded proof of concept of feasibility study to define if the immunosuppression associated with photodynamic therapy (PDT) can be blocked by treatment with cyclo-oxygenase-2 (COX-2) inhibitor celecoxib in comparison to placebo. PDT consists of application of the photosensitizer 5-aminolevulinic acid followed by treatment with a blue light. PDT is used to treat p...
