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

Blue light PDT has shown some success in treating BCCs, but more research is needed to evaluate this treatment modality further. The objective of this study is to evaluate the safety and efficacy of using photodynamic Therapy with Sonidegib for the treatment of multiple nodular basal cell carcinomas. Participants who meet eligibility criteria at baseline will receive Sonidegib 200 mg by mouth every day for 3 months. Participants will undergo three PDT sessions with topical application of ALA at Day 7, Day 45, and Day 75. The drug applied to the skin before the light treatment is an FDA approved drug called Levulan and has no known side effects. The light used to treat the lesion is blue light illumination using the BLU-U Blue Light Photodynamic Therapy Illuminator (Levulan-PDT). This treatment regimen is approved by the FDA to treat actinic keratoses, but is not approved to treat basal cell carcinoma. Use of the light can feel warm and may sting. Sonidegib (Odomzo) is a compound that was approved by the US Food and Drug Administration in July 2015 as a treatment option for BCC. Patients on Sonidegib may experience leg cramps, taste disturbance, or alopecia
