Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18 or older with HRD-positive advanced epithelial ovarian cancer who have responded to front-line chemotherapy.

Probably not a fit

Patients with non-HRD-positive tumors or those who have not responded adequately to initial chemotherapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effectiveness and safety of niraparib as a maintenance therapy for women with HRD-positive advanced epithelial ovarian cancer, including fallopian tube and primary peritoneal cancers, who have responded to initial chemotherapy combined with bevacizumab. The study is a multicenter, open-label, single-arm phase II trial aiming to enroll 116 patients. Participants must have undergone primary tumor surgery and completed at least two cycles of bevacizumab with platinum-based chemotherapy, achieving a complete or partial response. The trial will assess the impact of niraparib on disease progression in this patient population.

Why it matters

Potential benefit: If successful, this treatment could improve progression-free survival for patients with advanced ovarian cancer.

How similar studies have gone: Previous studies have shown promising results for niraparib in similar patient populations, indicating potential for success.
