Testing Niraparib for ovarian cancer
Official title: Alternative Dosing Of Niraparib To Decrease Dose Interruption In First Line Maintenance Treatment For Ovarian Cancer
A Phase II, Single-Arm Trial Assessing Alternative Dosing Of Niraparib To Decrease Dose Interruption In First Line Maintenance Treatment For Ovarian Cancer: Dose Escalation
Interventions
Niraparib
Niraparib (Zejula) will be administered as an oral treatment once daily (continuously in a 28-day cycle). Niraparib will be administered in a dose escalation design where patients will start at a dose of 100 mg PO daily for the first two cycles (28-days each cycle), if tolerated, the dose will be increased to 200 mg PO daily for the third and fourth cycle.

About This Trial
The goal of this clinical trial is to test alternative dosing of niraparib in patients with newly diagnosed high-grade, advanced stage ovarian cancer. The main questions it aims to answer are: What is the incidence of hematologic and other adverse events? What is the incidence of dose interruption, dose reduction and discontinuation? What is the length of time of progression-free survival at 24 months?
