Measure
Vismodegib and Radiation Therapy
150mg Vismodegib will be taken once a day, daily. Radiation therapy will be started after the patient has completed taking vismodegib for 12 weeks. The patient will take daily vismodegib through the completion of radiation therapy. The patient will receive radiation once a day, Monday through Friday, for 7 weeks. Each radiation treatment may take up to 30 minutes. 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.
