Optimization of photodynamic therapy with a novel self-adhesive 5-aminolaevulinic acid patch: results of two randomized controlled phase III studies

Abstract

PD P 506 A is an innovative, easy-to-handle 5-ALA patch for PDT of mild to moderate AK lesions. Compared with current PDT procedures, pretreatment (e.g. curettage) is not needed and handling is considerably facilitated. A single PDT treatment results in efficacy rates being statistically significantly superior to placebo and cryosurgery.
