Cabozantinib In Advanced Radioactive-Iodine Refractory Differentiated Thyroid Cancer.

"* All enrolled patients will receive cabozantinib at a fixed dose of 60 mg once a day (QD). Patients will continue study treatment until PD (either clinical or radiological), or until unacceptable toxicity, the need for another systemic anticancer treatment, or other reasons for treatment discontinuation.~* Patients will take the tablet(s) once daily at bed time except for Week 1 Day 1: the first dose of study treatment will be administered in the clinic so that each patient can be observed for initial tolerability. Subsequent doses will be self-administered at home. The tablets should be swallowed whole and not crushed and administered fasting for at least 2 hours before through 1 hour after. If a patient misses a dose, the missed dose should not be taken if it is less than 12 hours before the next dose."
