Niraparib vs Niraparib Plus Bevacizumab in Patients With Platinum/Taxane-based Chemotherapy in Advanced Ovarian Cancer

Niraparib vs Niraparib in Combination With Bevacizumab in Patients With Carboplatinum-taxane Based Chemotherapy in Advanced Ovarian Cancer (A Multicentre Randomised Phase III Trial)

This is an international, multicenter, randomized, open, Phase III trial to evaluate the efficacy and safety of carboplatin/paclitaxel/bevacizumab followed by bevacizumab and niraparib compared to carboplatin/paclitaxel followed by niraparib in patients with newly diagnosed advanced ovarian cancer.

Study Overview

• Status: Recruiting
• Conditions: Ovarian Cancer; Fallopian Tube Cancer; Peritoneal Cancer
• Intervention / Treatment: Drug: Carboplatin; Drug: Paclitaxel; Drug: Niraparib; Drug: Bevacizumab

Detailed Description

Eligible patients will be those patients with newly diagnosed, histologically confirmed, advanced (FIGO stage III/IV, except FIGO stage IIIA2 without nodal involvement) invasive high grade epithelial ovarian cancer, peritoneal cancer, or fallopian tube cancer, who have either undergone upfront primary surgery or plan to undergo chemotherapy with interval debulking surgery (IDS). In addition, patients should not have any medical contraindications that would exclude treatment with bevacizumab and/or niraparib.

All eligible patients will receive the first cycle of chemotherapy (carboplatin area under curve [AUC] 5 and paclitaxel 175 mg/m²) as part of Study Run-In-Period (cycle 1). In parallel, central laboratory will determine the breast cancer (BRCA) status in tumor tissue (tBRCA). All patients with a valid central tBRCA test result will be randomized prior to day 1 of cycle 2 in a 1:1 ratio in the following treatment arms:

Arm 1: Patients will receive further 5 cycles of carboplatin and paclitaxel q21d followed by niraparib once daily for up to a total of 3 years

Arm 2: Patients will receive further 5 cycles of carboplatin and paclitaxel plus bevacizumab q21d followed by bevacizumab q21d (for up to 1 year) and niraparib once daily for up to a total of 3 years.

The study aims to investigate, if the treatment strategy of carboplatin / paclitaxel / bevacizumab / niraparib is superior to the treatment of carboplatin / paclitaxel / niraparib-Inhibitor in an all-comer population.
