Study Arms:
- BF-200 ALA (Type: ACTIVE_COMPARATOR): Topical application of BF-200 ALA gel containing 78 mg/g 5-aminolevulinic acid (ALA). Application of a 1 mm thick layer covering each lesion and a 0.5 cm to 1 cm surrounding margin.
- MAL Cream (Type: ACTIVE_COMPARATOR): Topical application of MAL cream (Metvix) containing 160 mg/g methyl-aminolevulinate (MAL). Application of a 1 mm thick layer covering each lesion and a 0.5 cm to 1 cm surrounding margin.
- Vehicle (Type: PLACEBO_COMPARATOR): Topical application of matched Placebo to BF-200 ALA gel (without containing active ingredient) ). Application of a 1 mm thick layer covering each lesion and a 0.5 cm to 1 cm surrounding margin.
