Prospective, Controlled and Monocentric Study to Evaluate the Effects of Topical 3% Diclofenac in 2.5% Hyaluronic Acid Gel on Tumor Metabolism in the Treatment of Actinic Keratoses in Immunocompetent and Immunocompromised Patients
The rationale of this study is to investigate the effects of topical diclofenac on tumor metabolism in the treatment of actinic keratoses in immunocompetent and immunocompromised patients. Study hypothesis is that topical diclofenac lowers lactate level in skin biopsies of actinic keratoses. Planned number of patients is 38. This study is a monocenter study investigating the effects of 3% diclofenac in 2.5% hyaluronic acid gel on tumor metabolism in the treatment of actinic keratoses. Treatment duration is 3 months. Skin biopsies will be obtained before treatment, at the end of the treatment and four weeks after the treatment. Control biopsies at visit 1 and 3 are performed in healthy, sun damaged and untreated skin. Evaluation of efficacy will be performed at the end of the treatment and four weeks after the treatment. Duration of treatment is 3 months (±4 weeks). Approximately 0,5g Solaraze® 3% gel is applied on a 5cm x 5cm lesion. Solaraze® 3% gel is applied twice daily on the study lesions.
