Long‐term (6 and 12 months) follow‐up of two prospective, randomized, controlled phase III trials of photodynamic therapy with BF‐200 ALA and methyl aminolaevulinate for the treatment of actinic keratosis

Abstract

The FUP data confirmed the high efficacy and safety of PDT with BF-200 ALA. The slightly lower recurrence rates after BF-200 ALA treatment compared with MAL treatment enhanced the better treatment outcome due to the significantly superior efficacy.
