This study will investigate the efficacy and safety of niraparib maintenance re-treatment in patients with PSR non-mucinous EOC, who have previously received maintenance therapy with a Polyadenosine 5'diphosphoribose [poly (ADP ribose)] polymerisation inhibitor (PARPi) and a complete or partial radiological response to subsequent treatment with platinum-based chemotherapy or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy). Patients will be enrolled, given niraparib and anlotinib maintenance treatment until disease progression or untolerated toxicity.
This study will be an open-label, single-arm, prospective, exploratory phase II trial to investigate the efficacy and safety of niraparib maintenance retreatment in platinum- sensitive recurrent (PSR) epithelial ovarian cancer (EOC) patients (including patients with primary peritoneal and/or fallopian tube cancer).
