Interventions

COMBINATION_PRODUCT

BF-200 ALA and red light LED lamp

Up to two PDTs using a RhodoLED lamp (RhodoLED® XL or BF-RhodoLED®) (ALA-PDT, Ameluz®-PDT): Topical application of up to 3 tubes BF-200 ALA on the expanded treatment field (up to 240 cm²), followed by red light illumination with a RhodoLED lamp after 3 h incubation of study medication under occlusive dressing. PDT-1 will be performed at Visit 2. Clinical clearance will be assessed 12 weeks after PDT-1 (Visit 4). In case of remaining lesions at Visit 4, PDT-2 will be performed at the same visit.
