NCT00308867
Brief Summary:
The aim of this study is to investigate how the efficacy and tolerability of PD P 506 A-PDT relate to the commonly used cryosurgery in the treatment of mild to moderate AK lesions located on the head. To be able to quantify the effect the patient will be allocated to one of three treatments: PD P 506 A-PDT, cryosurgery or placebo-PDT.
Detailed Description:
Actinic keratosis (AK) is a pre-cancerous skin abnormality usually caused by sun exposure. Actinic keratoses occur most commonly in fair skin, especially in the elderly. They mainly occur in sun-exposed skin areas like head and hands. It is standard of care to remove AK when diagnosed, which can be achieved by either physical ablation, chemotherapeutic agents or photodynamic therapy (PDT). In Europe, cryosurgery is the method primarily used and will therefore serve as comparator therapy for PD P 506 A-PDT. A placebo control will be necessary to validate the test system. While the comparison of PD P 506 A-PDT and cryosurgery is an open comparison, placebo-PDT and PD P 506 A-PDT will be allocated in a double-blind manner.
