Study to Evaluate the Safety and Efficacy of BF-200 ALA (Ameluz®) and BF-RhodoLED® in the Treatment of Superficial Basal Cell Carcinoma (sBCC) With Photodynamic Therapy (PDT).

The Main Target Lesion will be marked by at least 3 ink marks prior to PDT to enable precise excision for histopathological assessment 12 weeks after the first or second PDT cycle dependent on the clearance status of the lesion. All target lesions should be prepared prior to drug application by degreasing, removal of all scabs and crusts, and roughening of the surface, if appropriate. Bleeding should be avoided. The formulations will then be applied to the lesions (maximal combined lesion area incl. margin is 20 cm²) located in 1 to 2 illumination areas. The medication should be applied to the entire lesion(s) plus a 0.5 - 1.0 cm margin surrounding each lesion at a thickness of 1 mm, allowed to dry (for approximately 10 minutes), covered with occlusive dressing, and incubated for approximately 3 h. Thereafter, any remnants of the IMP will be removed carefully and the PDT illumination will be administered using the light emitting diode (LED) red light device BF-RhodoLED®.
