Chiauranib in Combination With Chemotherapy in Patients With Ovarian Cancer

A Multi-center, Phase Ⅱ Clinical Trial of Chiauranib Plus Chemotherapy in Relapsed/Refractory Ovarian Cancer

This clinical trial will evaluate the efficacy and safety of chiauranib added to chemotherapy in patients with relapsed or refractory ovarian cancer, in the meantime, explore the pharmacokinetics characteristic after the combined treatment.

This clinical trial will evaluate the efficacy and safety include adverse events, vital signs, laboratory tests, etc., of chiauranib added to chemotherapy (Paclitaxel/Etoposide) in patients with relapsed or refractory epithelial ovarian, fallopian tube or primary peritoneal cancer, in the meantime, explore the pharmacokinetics characteristic after the combined treatment.
