Clinical Pharmacokinetics and Safety of a 10% Aminolevulinic Acid Hydrochloride Nanoemulsion Gel (BF-200 ALA) in Photodynamic Therapy of Patients Extensively Affected With Actinic Keratosis: Results of 2 Maximal Usage Pharmacokinetic Trials.

ABSTRACT: The nanoemulsion-based 10% aminolevulinic acid (ALA) hydrochloride gel BF-200 ALA optimizes epidermal penetration of its active ingredient and is approved for topical photodynamic therapy (PDT) for the treatment of actinic keratosis in the United States and Europe. To characterize systemic absorption from dermal application during PDT, ALA and its key active metabolite protoporphyrin IX (PpIX) were analyzed in 2 maximal usage pharmacokinetic trials (MUsT) in patients severely affected with actinic keratosis. The primary objective of both MUsTs was to assess baseline-adjusted plasma concentration-time curves for ALA and PpIX after a single PDT treatment applying either 2 g (1 tube) of BF-200 ALA on the face (MUsT-1) or applying 6 g (3 tubes) of BF-200 ALA on the face/scalp or body periphery
