About

Radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC) is a great challenge in the treatment of thyroid cancer. Tyrosine kinase inhibitors (TKIs), like sorafenib and lenvatinib which have been approved by food and drug administration (FDA), could not be affordable for most of the Chinese patients. Apatinib is a highly selective VEGFR2 inhibitor and reduces the angiogenesis of tumor effectively, which is a proven and effective drug in many solid tumors. A phase II study aims to assess the efficacy and safety of apatinib in RAIR-DTC ,which enrolled 20 patients and 10 of them had obtained a shout-term efficacy, demonstrating the peculiar potential in treatment of RAIR-DTC. In this study, the investigators aim to further explore the efficacy and safety of apatinib in RAIR-DTC.

Full description

Primary Outcome Measure: Progression free survival of apatinib in RAIR-DTC. Secondary Outcome Measures: Disease control rate, objective response rate, duration of response, changes of Tg and TgAb level in serum, overall survival, side effects and quality of life.

  • Pregnancy test (serum) has to be performed for woman of childbearing age within 7 days before enrolment and the test result must be negative. They shall take appropriate methods for contraception during the study until the 8th week post the last administration of study drug. For men, (previous surgical sterilization accepted), shall agree to take appropriate methods of contraception during the study until the 8th week post the last administration of study drug.
  • Patient has to voluntarily join the study and sign the Informed Consent Form for the study.
  • Good compliance is expected, according to the program requirements follow-up and recorded adverse reactions.

Exclusion criteria
