Blue-Light Photodynamic Therapy and Sonidegib for Multiple Basal Cell Carcinomas

Prior to ALA application, the areas will be cleaned with alcohol and debrided gently with prep tape. ALA will then be applied to each of the study lesions and allowed to incubate for 3 hours with occlusion prior to the PDT.

Participants will be subjected to dose illumination with blue light (BLU-U Model 4170E) at a power fluence of 20 mW/cm2 for a total time of 16 minutes and 40 seconds (1,000 seconds). This will result in a total light delivery dose of 20 J/cm2.
