The product label notes that this indication is approved under accelerated approval based on overall response rate and duration of response and that continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). This indication is based on ARROW (NCT03037385), a multicenter, open-label, multi-cohort clinical trial where all enrolled patients had papillary thyroid cancer.
