Criteria

Inclusion Criteria:

1. 18 years of age or older, female, any race

2. Histologically diagnosed ovarian cancer, fallopian tube cancer or primary peritoneal cancer

3. High grade (or grade 3) serous histology or known to have gBRCAmut

4. Has received at least 2 previous lines of platinum-containing therapy (not necessarily consecutive), and has disease that was considered platinum sensitive following the penultimate platinum line (more than 6-months period between penultimate platinum regimen and progression of disease)

5. Has responded to the last platinum line (PR or CR)

6. No more than 8 weeks have elapsed from completion of the last platinum regimen and the patient is still not progressing after response

7. Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1

8. Adequate bone marrow, kidney and liver function, defined as follows:

1. Absolute neutrophil count ≥ 1,500/µL

2. Platelets ≥ 100,000/µL

3. Hemoglobin ≥ 9 g/dL

4. Serum creatinine ≤ 1.5 x upper limit of normal (ULN) or calculated creatinine clearance ≥ 30 mL/min using the Cockcroft-Gault equation

5. Total bilirubin ≤ 1.5 x ULN (≤2.0 in patients with known Gilberts syndrome) OR direct bilirubin ≤ 1 x ULN

6. Aspartate aminotransferase and alanine aminotransferase ≤ 2.5 x ULN unless liver metastases are present, in which case they must be ≤ 5 x ULN

9. Patient receiving corticosteroids may continue as long as their dose is stable for least 4 weeks prior to initiating protocol therapy.

10. Patient must have a negative urine or serum pregnancy test within 7 days prior to taking study treatment if childbearing potential and agrees to abstain from activities that could result in pregnancy from screening through 180 days after the last dose of study treatment or use adequate barrier methods throughout the study. Non-childbearing potential is defined as follows (by other than medical reasons): ≥45 years of age and has not had menses for >1 year; patients with amenorrhea for <2 years without history of a hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation; Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records, otherwise the patient must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 180 days after the last dose of study treatment.

11. Patient must agree to not breastfeed during the study or for 180 days after the last dose of study treatment.

12. Patient must be able to understand the study procedures and agree to participate in the study by providing written informed consent.

13. Patients must have normal blood pressure or adequately treated and controlled hypertension. (i.e. systolic BP ≤ 140 mmHg and diastolic BP ≤ 90 mmHg)

Exclusion Criteria:

1. Patient simultaneously enrolled in any interventional clinical trial

2. Invasive cancer other than ovarian cancer within 2 years (except basal or squamous cell carcinoma of the skin that has been definitely treated)

3. Patient with known, symptomatic brain or leptomeningeal metastases

4. Patient with immunocompromised status

5. Patient with known active hepatic disease

6. Prior treatment with a known PARP inhibitor

7. Patient who has had major surgery ≤ 3 weeks prior to initiating protocol therapy and participant must have recovered from any surgical effects.

8. Patient who has received investigational therapy ≤ 4 weeks, or within a time interval less than at least 5 half-lives of the investigational agent, whichever is shorter, prior initiating protocol therapy.

9. Patient has had radiation therapy encompassing >20% of the bone marrow within 2 weeks prior to day 1 of protocol therapy

10. Patient has had any radiation therapy within 1 week prior to day 1 of protocol therapy.

11. Patient with known hypersensitivity to niraparib components or excipients.

12. Patient has received a transfusion (platelets or red blood cells) ≤ 4 weeks prior to initiating protocol therapy.

13. Patient has received colony stimulating factors (e.g., granulocyte colony-stimulating factor, granulocyte macrophage colony stimulating factor, or recombinant erythropoietin) within 4 weeks prior initiating protocol therapy.

14. Patient has had any known Grade 3 or 4 anemia, neutropenia or thrombocytopenia due to prior chemotherapy that persisted > 4 weeks and was related to the most recent treatment.

15. Patient with any known history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)

16. Patient with a serious, uncontrolled medical disorder. Examples include, but are not limited to, nonmalignant systemic disease, active, uncontrolled infection, uncontrolled ventricular arrhythmia, recent (within 90 days) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, or any psychiatric disorder that prohibits obtaining informed consent
