Anlotinib for Patients With Platinum Resistant or Refractory Ovarian Cancer

A Phase II Study of Anlotinib for Patients With Platinum Resistant or Refractory Ovarian Cancer

The purpose of the study is to evaluate the efficacy and toxicity of anlotinib in patients with platinum resistant or refractory ovarian cancer

Ovarian cancer is the leading cause of death for patients with gynecologic malignancies. In most cases, the disease is diagnosed at an advanced stage and approximately 75% of patients will eventually experience disease recurrence. However, the overall response rates of second-line chemotherapy for recurrent ovarian cancer are only 20-27%. Therefore, it is important to seek alternative agent that can improve the outcome. Anlotinib is a new, orally administered tyrosine kinase inhibitor that targets VEGFR,FGFR,PDGFR,and c-kit,. The preclinical studies suggest anlotinib may be effective in other cancers such as ovarian cancer. Therefore, the purpose of this study is to test the efficacy and safety of the study drug anlotinib.
