The purpose of this study is to determine how well a daily dose of 150 mg of Erivedge (vismodegib) reduces Keratocystic odontogenic tumor (KCOT) size, and to evaluate the safety of this dose. Erivedge is FDA-approved for use in adults with a specific type of skin cancer. However, the drug is experimental for patients with KCOT.

Study summary:

This is a single-center, interventional, single-arm, open-label, two-cohort clinical trial. A total of 20 patients will be enrolled (10 with NBCCS-associated KCOT and 10 with sporadic KCOT) over a period of 2 years. This is a 3 year study where each patient will undergo up to 1 year of treatment and up to 2 years of post-treatment follow-up. All patients will be assessed for safety and efficacy of the study drug GDC-0449 (Vismodegib).
