Brief Summary

This study will be an open-label, single-arm, prospective, exploratory phase II trial to investigate the efficacy and safety of niraparib maintenance retreatment in platinum- sensitive recurrent (PSR) epithelial ovarian cancer (EOC) patients (including patients with primary peritoneal and/or fallopian tube cancer).

Detailed Description

This study will investigate the efficacy and safety of niraparib maintenance re-treatment in patients with PSR non-mucinous EOC, who have previously received maintenance therapy with a Polyadenosine 5'diphosphoribose [poly (ADP ribose)] polymerisation inhibitor (PARPi) and a complete or partial radiological response to subsequent treatment with platinum-based chemotherapy or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy). Patients will be enrolled, given niraparib and anlotinib maintenance treatment until disease progression or untolerated toxicity.

Intervention Type: DRUG

Niraparib 200 or 300mg* QD PO continually;

*The starting dose of niraparib was individualized based on patients' bodyweight and baseline platelet count; 200 mg QD for Patients with baseline body weight <77 kg or platelets count <150,000/μL;300 mg QD for Patients with baseline body weight ≥77 kg and platelets count ≥150,000/μL.

For patients who had experienced grade 4 adverse events from previous use of PARPi, niraparib staring dose was 200 mg QD.

Eligibility Criteria

Inclusion Criteria

• Provision of informed consent prior to any study specific procedures.
• Female patients ≥18 years of age, with histologically diagnosed platinum sensitive recurrent high-grade serous or endometrioid epithelial ovarian cancer (EOC) (including primary peritoneal and/or fallopian tube cancer).
• BRCA mutation status is known.
• Patients must have received one prior PARPi therapy, PARPi therapy includes any agent (including niraparib) used in a maintenance setting and the duration of maintenance treatment ≥6 months.
• Patients had received ≤3 lines of chemotherapy, the time between the penultimate line of platinum-containing chemotherapy and the last platinum-containing chemotherapy was > 6 months. For example, if a patient receives a non-platinum type of chemotherapy between the penultimate line of platinum-containing chemotherapy and the last platinum-containing chemotherapy, patient will be eligible if all the eligibility criteria are met.
• The most recent round of platinum-containing chemotherapy should have included ≥4 cycles of treatment , in the opinion of the investigator, in response (partial or complete radiological response) or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy) .
• Patients must have either CA-125 in the normal range or CA-125 decrease by more than 90% during last line chemotherapy and that is stable for at least 7 days (ie, no increase > 15% from nadir).
• Patients can have received bevacizumab during this course of treatment. Bevacizumab use as part of an earlier line of therapy is permitted.
• Patients must be enrolled within 8 weeks of their last dose of chemotherapy (last dose is the day of the last infusion).
• Patients must have a life expectancy ≥4 months.
• Eastern Cooperative Oncology Group performance status 0-2.
• Patients must have normal organ and bone marrow function, defined as follows: Absolute neutrophil count ≥ 1,500/μL; Platelets ≥ 100,000/μL; Hemoglobin ≥ 10 g/dL; Serum creatinine ≤ 1.5 x upper limit of normal (ULN) or calculated creatinine clearance ≥ 60 mL/min using the Cockcroft-Gault equation; Total bilirubin ≤ 1.5 x ULN OR direct bilirubin ≤ 1 x ULN; Aspartate aminotransferase and alanine aminotransferase ≤ 2.5 x ULN unless liver metastases are present, in which case they must be ≤ 5 x ULN
• Negative serum or urine pregnancy test prior to receiving the first dose of study treatment and willing to use adequate contraception to prevent pregnancy or must agree to abstain from heterosexual activity throughout the study, starting with enrollment through 90 days after the last dose of study treatment; or women of with no potential fertility.
• Ability to comply with protocol.

• Major surgery performed within 3 weeks before enrollment, or any surgical effects that have not recovered from the surgery, or chemotherapy.
