Background
DIFFERENTIATED THYROID CANCER, SECONDARY
In the phase 2 double‐blind Study 211, a starting dose of lenvatinib 18 mg/day was compared with the approved starting dose of 24 mg/day in patients with radioiodine‐refractory differentiated thyroid cancer (RR‐DTC). Predefined criteria for noninferiority for efficacy in the 18 mg arm were not met; safety was similar in both arms. Impact of lenvatinib treatment on health‐related quality‐of‐life (HRQoL) was a secondary endpoint of Study 211.
