Study Summary

The aim of this study is to assess the pharmacokinetics (PK) of the parent drug 5-aminolevulinic acid (ALA) and its active metabolite protoporphyrin IX (PpIX) during photodynamic therapy with 3 tubes of BF-200 ALA 10% gel (Ameluz®) in combination with the BF-RhodoLED® lamp in the systemic circulation of diseased individuals presenting with actinic keratosis (AK) on the face/scalp or in the periphery (neck/trunk/extremities) along with subjects' safety/tolerability during and after treatment.

Primary Outcome

Blood samples for ALA analysis for each subject were collected, starting at Visit 1 and then 0.5h prior to BF-200 ALA application for up to 10h afterwards. The concentrations of ALA in plasma were measured by an analytical laboratory using validated, internally standardized liquid chromatography-tandem mass spectrometry methods.
