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

This research study is testing combination Blue-light photodynamic therapy and Sonidegib as a possible treatment for people with multiple basal cell carcinoma lesions. Basal cell carcinoma lesions are typically treated by freezing the lesion or surgically removing the lesion. These types of treatment can cause scarring. Photodynamic therapy uses light along with a drug applied to the skin to kill the cancer cells and cause them to break apart. The light used can cause the skin to feel warm, but does not cause scarring.
