What this study is testing
The primary aim of this study is to show that the recurrence free survival (RFS) in patients receiving three cycles of chemotherapy followed by maintenance with niraparib is not inferior to 6 cycles of chemotherapy followed by niraparib in advanced HRDpositive high-grade ovarian cancer patients with no residual tumor mass following primary tumor debulking.

A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Written informed consent and obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.
- Postmenopausal or evidence of non-childbearing status for women of childbearing potential prior to the first dose of study treatment. Female patients of childbearing potential must have a negative serum pregnancy test result ≤3 days prior to administration of the first dose of study treatment. Patients are considered to be of childbearing potential unless 1 of the following applies: a. Considered to be permanently sterile. Permanent sterilization includes hysterectomy, bilateral salpingectomy, and/or bilateral oophorectomy; or b. Is postmenopausal, defined as no menses for at least 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level consistently in the postmenopausal range (30 mIU/mL or higher) may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy; however, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient to confirm a postmenopausal state. Female patients of reproductive potential must practice highly effective methods (failure rate < 1% per year) of contraception with their partners, if of reproductive potential, during treatment and for 6 months following the last dose of chemotherapy or the last dose of niraparib, whichever occurs later, or longer if requested by local authorities. Highly effective contraception includes: Ongoing use of progesterone only injectable or implantable contraceptives; Placement of an intrauterine device (IUD) or intrauterine system (IUS); Bilateral tubal occlusion; Sexual abstinence as defined as complete or true abstinence, acceptable only when it is the usual and preferred lifestyle of the patient; periodic abstinence (e.g., calendar, symptothermal, post-ovulation methods) is not acceptable; or Sterilization of the male partner, with appropriate post-vasectomy documentation of absence of sperm in ejaculate.
- Female patient, age ≥ 18 years.
- FIGO Stage III-IV high-grade ovarian cancer (all histological types, except mucinous histology)
- Complete primary debulked patients (without any macroscopic residuals), confirmed by CT-Scan postoperatively.
- Patients must have formalin-fixed, paraffin-embedded tumor samples available from the primary cancer for central NGS analysis and must be HRD positive defined as BRCAmut independent of NOGGO GIS Score OR NOGGO GIS Score >83 independent of BRCA status, based on these results
You likely can't join if
- Non-epithelial origin of the ovary, the fallopian tube or the peritoneum (i.e., germ cell tumors) and Ovarian tumors of low malignant potential (e.g., borderline tumors), or mucinous carcinoma of the ovary.
- Bevacizumab is planned to be given together with first line chemotherapy or as maintenance.
- Clinically significant cardiovascular disease: a. Cerebrovascular accident or myocardial infarction or unstable angina ≤6 months before start of study treatment b. Severe cardiac arrhythmia (recent event or active or uncontrolled) c. New York Heart Association grade ≥2 congestive heart failure d. Uncontrolled hypertension (defined as systolic blood pressure >140 mmHg and/or diastolic blood pressure >90 mmHg), or history of hypertensive crisis, or hypertensive encephalopathy or posterior reversible encephalopathy syndrome e. History of stroke or transient ischemic attack ≤6 months before start of study treatment f. Coronary/peripheral artery bypass graft ≤6 months before start of study treatment g. Deep vein thrombosis or thromboembolic events ≤1 month before start of study treatment
- History or evidence of brain metastases or spinal cord compression.
- Known history of MDS or a pre-treatment cytogenetic testing result at risk for a diagnosis of MDS/AML.
- Current, clinically relevant bowel obstruction at the time of randomization.
