Abstract

Insights

Anlotinib significantly improved progression-free survival in patients with radioiodine-refractory differentiated thyroid carcinoma (RAIR-DTC). This multikinase inhibitor showed promising efficacy and favorable safety, warranting further investigation for advanced RAIR-DTC.

Area of Science:

  • Oncology
  • Pharmacology
  • Clinical Trials

Background:

  • Radioiodine-refractory differentiated thyroid carcinoma (RAIR-DTC) requires novel antiangiogenic agents.
  • Existing treatments need optimization for greater target-binding and improved pharmacokinetics.

Purpose of the Study:

  • To investigate the efficacy and safety of anlotinib, a multikinase inhibitor, in patients with RAIR-DTC.
  • To evaluate anlotinib's potential as a novel antiangiogenic therapy for advanced RAIR-DTC.

Main Methods:

  • Phase II, randomized, double-blind, placebo-controlled trial.
  • 12 mg anlotinib daily (14 days/3 weeks) or placebo in locally advanced/metastatic RAIR-DTC patients (18-70 years).
  • Primary endpoint: Progression-Free Survival (PFS); Secondary endpoints: Overall Survival (OS) and safety.

Main Results:

  • Anlotinib significantly prolonged median PFS (40.5 months vs. 8.4 months; HR=0.21, P<0.001).
  • A trend of overall survival benefit was observed with anlotinib (HR=0.57).
  • All anlotinib patients experienced adverse events; 10.5% discontinued due to AEs.

Conclusions:

  • Anlotinib demonstrates promising efficacy and favorable tolerance in treating advanced RAIR-DTC.
  • Further research is supported to establish anlotinib's role in RAIR-DTC treatment.
  • Anlotinib represents a potential new therapeutic option for this challenging disease.
