A pivotal phase 3 trial (CELESTIAL) of cabozantinib is ongoing in patients with advanced HCC, and Exelixis has guided that data from the trial are expected in 2017.

Orphan drug status is granted to treatments for diseases that affect fewer than 200,000 people in the U.S. and provides certain incentives for medications intended for the treatment, diagnosis or prevention of rare diseases. At present, these incentives include seven years of marketing exclusivity for the orphan indication, certain federal grants, tax credits and waiver of certain FDA fees.

About the CELESTIAL Trial

CELESTIAL is designed to enroll 760 patients with advanced HCC who received prior sorafenib. Patients are randomized 2:1 to receive 60 mg of cabozantinib daily or placebo. The primary endpoint for the trial is overall survival, and secondary endpoints include objective response rate and progression-free survival. Exploratory endpoints include patient-reported outcomes, biomarkers and safety. The CELESTIAL trial is being conducted at more than 100 sites globally in 19 countries.
