A Phase III Randomized Double-Blind Trial of Maintenance with Niraparib Versus Placebo in Patients with Platinum Sensitive Ovarian Cancer


Trial Phase

Phase III

Trial Purpose and Description

Trial Purpose

This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of niraparib as maintenance in platinum sensitive ovarian cancer patients who have either gBRCAmut or a tumor with high-grade serous histology and who have responded to their most recent chemotherapy containing a platinum agent. Niraparib is an orally active PARP inhibitor. Niraparib or placebo (in a 2:1 ratio) will be administered once daily continuously during a 28-day cycle.
