Brief Summary
Multicenter, randomized, open label study including patients with advanced HRDpositive high-grade ovarian cancer, fallopian tube cancer, primary peritoneal cancer and clear cell carcinoma of the ovary with no residual tumor mass following primary tumor debulking to determine recurrence free survival in patients treated with 3 cycles carboplatin + paclitaxel and maintenance therapy with niraparib vs. 6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib.

Study Arms (2)
Arm A (3 cycles of chemotherapy + maintenance therapy with niraparib)
EXPERIMENTAL3 cycles carboplatin + paclitaxel maintenance therapy with niraparib (starting dose 200 mg QD or 300 mg QD); maintenance continues until disease progression and/or death, unacceptable adverse event/s, patient and/or investigator decision, other protocol stopping criteria.
Arm B (6 cycles of chemotherapy + maintenance therapy with niraparib)
ACTIVE COMPARATOR6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib (starting dose 200 mg QD or 300 mg QD); maintenance continues until disease progression and/or death, unacceptable adverse event/s, patient and/or investigator decision, other protocol stopping criteria.
Interventions
We hypothesise that recurrence free survival in patients receiving 3 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.
Standard chemotherapy as comparator
Eligibility Criteria
You may qualify if:
- Written informed consent and obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.
- 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 HRDpositive defined as BRCAmut independent of NOGGO GIS Score OR NOGGO GIS Score \>83 independent of BRCA status, based on these results.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
- Patients must be able to take oral medications.
- Synchronous and secondary malignancies are allowed if the prognosis of the ovarian cancer is not affected. The investigator must contact the medical monitoring team before enrolling the patient in the clinical trial.
- Patients must have normal organ and bone marrow function:
- Hemoglobin ≥ 10.0 g/dL independent of transfusion ≤ 14 days prior to screening hemoglobin assessment
- Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
- Platelet count ≥ 100 x 109/L
- Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN); \< 2 × ULN if hyperbilirubinemia is due to Gilbert's syndrome
- Aspartate aminotransferase /Serum Glutamic Oxaloacetic Transaminase (ASAT/SGOT)) and Alanine aminotransferase /Serum Glutamic Pyruvate Transaminase (ALAT/SGPT)) ≤ 2,5 x ULN
- Serum creatinine ≤ 1.5 x institutional ULN and creatinine clearance \> 30 mL/min.
- +5 more criteria
You may not qualify 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.
- Low-grade ovarian, fallopian tube or peritoneal cancer.
- Has known hypersensitivity to any of the study drugs or any of the excipients of any of the study drugs.
- Has known hypersensitivity to platin-containing compounds other than carboplatin.
- Patients posttransplant, including previous allogeneic bone marrow transplant.
- Has undergone interval debulking of the tumor.
- Has received any anti-cancer therapy for ovarian cancer other than primary surgery.
- Administration of other simultaneous chemotherapy drugs, any other anti-cancer therapy or anti-neoplastic hormonal therapy, or simultaneous radiotherapy during the trial treatment period (hormonal replacement therapy is permitted as are steroidal antiemetics).
- Has received prior treatment with a PARP inhibitor or has participated in a trial where any treatment arm included the administration of a PARP inhibitor.
- Bevacizumab is planned to be given together with first line chemotherapy or as maintenance.
- Clinically significant cardiovascular disease:
- Cerebrovascular accident or myocardial infarction or unstable angina ≤6 months before start of study treatment
- Severe cardiac arrhythmia (recent event or active or uncontrolled)
- New York Heart Association grade ≥2 congestive heart failure
- 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
