Randomized Controlled Trial Multicenter Study Comparative StudyA randomized, intraindividual, non-inferiority, Phase III study comparing daylight photodynamic therapy with BF-200 ALA gel and MAL cream for the treatment of actinic keratosis.
The most effective treatment modality for actinic keratosis (AK) is photodynamic therapy (PDT). Major obstacles of PDT are the need of a special illumination device and pain accompanying the illumination. These issues may be overcome by replacing an artificial high-power light source with natural daylight for more extended illumination at lower light doses. ⋯ Daylight PDT of AK with BF-200 ALA is well-tolerated and non-inferior to MAL/dPDT. The study demonstrates a trend towards higher efficacies after 3 months and significantly lower recurrence rates after 1 year follow-up.
