Phase II Study of Radiation Therapy and Vismodegib for Advanced Head/Neck Basal Cell Carcinoma

Vismodegib will be taken daily for 12 weeks. It should be taken at approximately the same time each day. Patients will be given a supply of vismodegib on Week 1, Day 1 to last until their next study visit. They will be asked to keep a record of each dose of vismodegib you take. After 12 weeks, they will be evaluated again to make sure they are still eligible to participate in the study. If they are eligible to continue, they will continue taking vismodeib daily as before for another 7 weeks while they receive radiation therapy.

Radiation therapy will be started after the patient has finished taking vismodegib for 12 weeks. They will receive radiation once a day, Monday through Friday, for 7 weeks. Each radiation treatment may take up to 30 minutes.
