A Study of Niraparib in Patients With Ovarian Cancer Who Have Received Three or Four Previous Chemotherapy Regimens (QUADRA)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is a Phase 2, open-label, single arm study to evaluate the safety and efficacy of niraparib in ovarian cancer patients who have received three or four previous chemotherapy regimens. Niraparib is an orally active PARP inhibitor. Niraparib will be administered once daily continuously during a 28-day cycle. Health-related quality of life will be measured by Eastern Cooperative Oncology Group performance status (ECOG). Safety and tolerability will be assessed by clinical review of adverse events (AEs), physical examinations, electrocardiograms (ECGs), RECIST tumor assessments and safety laboratory values.
A Phase 2, Open-Label, Single-Arm Study to Evaluate the Safety and Efficacy of Niraparib in Patients With Advanced, Relapsed, High-Grade Serous Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Who Have Received Three or Four Previous Chemotherapy Regimens

Evaluate antitumor activity of niraparib [ Time Frame: 6 months ]
Secondary Outcome Measures
Evaluate durability of anti-cancer activity (i.e. time from first response, CR or PR until disease progression). [ Time Frame: 6 months ]
The evaluation is measured by clinical review of adverse events (AEs), physical examinations, electrocardiograms (ECGs), RECIST tumor assessments and safety laboratory values.
Evaluate antitumor activity of niraparib in HRD+ and gBRCAmut [ Time Frame: 6 months ]
To evaluate antitumor activity of niraparib in homologous recombination deficiency (HRD) positive patients and in gBRCAmut positive patients
Disease Control Rate (DCR) [ Time Frame: 6 months ]
Progression Free Survival [ Time Frame: 6 months ]
Time from enrollment to the earlier date of assessment of progression by any cause in the absence of progression per RECIST (v.1.1) or clinical criteria, or death.
Overall Survival [ Time Frame: 6 months ]
Time from enrollment to the date of death by any cause.
Evaluate the safety and tolerability of niraparib in ovarian cancer patients (Review of adverse events, concomitant medications, physical exams, electrocardiograms (ECGs), and safety lab values.) [ Time Frame: 6 months ]
