Brief Summary:
The purpose of this study is to evaluate the safety and efficacy of niraparib in participants with advanced, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received 3 or 4 previous chemotherapy regimens.

Condition or disease Intervention/treatment Phase
Ovarian Cancer Fallopian Tube Cancer Primary Peritoneal Cancer Drug: Niraparib Phase 2

Detailed Description:

The drug being tested in this study is called niraparib. Niraparib is being tested to treat people who have the homologous recombination deficiency (HRD)-positive, advanced, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer. This study will look at the efficacy and safety of niraparib in Japanese participants.

The study will enroll approximately 16 participants. Participants will be enrolled to one group and after that will be asked to take niraparib capsules at the same time each day throughout the study:

- Niraparib 300 mg

This multi-center trial will be conducted in Japan. The overall time to participate in this study is approximately 23 months. Participants will make multiple visits to the clinic in the treatment period, and the post-treatment period including follow-up assessments after the last dose of the study drug.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: Until disease progression or death (Up to 3.8 years) ]
    ORR was defined as the percentage of participants achieving CR or PR as assessed by the Investigator per RECIST v.1.1. CR was defined as disappearance of all target lesions and PR was defined as at least a 30% decrease in SoD of target lesions, taking as a reference the Baseline SoD.


Secondary Outcome Measures :
  1. Duration of Response (DOR) [ Time Frame: Until disease progression or death (Up to 3.8 years) ]
    DOR was defined as the time from the first documented CR or PR per RECIST v.1.1 to disease recurrence or objective disease progression whichever occurs first. CR was defined as disappearance of all target lesions and PR was defined as at least a 30% decrease in SoD of target lesions, taking as a reference the Baseline SoD.

  2. Disease Control Rate (DCR) [ Time Frame: Until disease progression or death (Up to 3.8 years) ]
    DCR was defined as the percentage of participants achieving CR, PR or SD as assessed by the Investigator per RECIST v.1.1. CR was defined as disappearance of all target lesions and PR was defined as at least a 30% decrease in SoD of target lesions, taking as a reference the Baseline SoD. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD was defined as at least a 20% increase in the SoD of target lesions, taking as a reference the smallest (nadir) SoD since (and including) Baseline.

  3. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An adverse event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE was defined as an adverse event with an onset that occurs after receiving study drug.

  4. Number of Participants With Grade 3 or Higher TEAEs [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A TEAE was defined as an adverse event with an onset that occurs after receiving study drug. A severity grade was defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4.03. As per NCI-CTCAE, Grade 1 scales as Mild; Grade 2 scales as Moderate; Grade 3 scales as severe or medically significant but not immediately life threatening; Grade 4 scales as life-threatening consequences; and Grade 5 scales as death related to AE.

  5. Number of Participants With Serious TEAEs [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) was any AE that results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in significant disability or incapacity, is a congenital anomaly/birth defect or is a medically important event. TEAE was defined as an adverse event with an onset that occurs after receiving study drug.

  6. Number of Participants With TEAEs Leading to Drug Discontinuation [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A TEAE was defined as an adverse event with an onset that occurs after receiving study drug.

  7. Number of Participants With TEAEs Leading to Dose Interruption [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A TEAE was defined as an adverse event with an onset that occurs after receiving study drug.

  8. Number of Participants With TEAEs Leading to Dose Reduction [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    An AE was defined as any untoward medical occurrence in a participant who has enrolled in a study; it does not necessarily have a causal relationship with this treatment. A TEAE was defined as an adverse event with an onset that occurs after receiving study drug.

  9. Progression Free Survival (PFS) [ Time Frame: Until disease progression or death (Up to 3.8 years) ]
    PFS was defined as the time in months from the date of first study drug administration to the date of first documentation of PD or death as assessed by the RECIST v.1.1. Per RECIST 1.1, PD was defined as at least a 20% increase in the SoD of target lesions, taking as a reference the smallest (nadir) SoD since (and including) Baseline.

  10. Overall Survival (OS) [ Time Frame: From first dose of study drug up to 30 days after the last dose or beginning of subsequent anticancer therapy, whichever came first (Up to 3.8 years) ]
    OS was defined as the time in months from the study enrollment to death due to any cause.

Criteria

Inclusion Criteria

  1. Japanese female participants aged 20 years or older on the day of signing informed consent.
  2. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the participant at any time without prejudice to future medical care.

  3. Participants must agree to undergo tumor homologous recombination deficiency/deficient (HRD) testing, and this test result must show that participants have an HRD-positive tumor (defined by the presence of a deleterious or suspected deleterious breast cancer gene (BRCA) mutation or be positive for genomic instability) by the central laboratory selected by the sponsor.

    Note 1: The study HRD test result must be received prior to enrollment. The tumor sample may be submitted for HRD testing prior to the screening period (ie, within 40 days before Cycle 1 Day 1) if the consent has been obtained and it appears the participant is likely to meet other eligibility requirements.

    Note 2: If historic blood germline BRCA mutation (gBRCAmut) is detected by a prior gBRCAmut testing, then tumor HRD sample test results are not required prior to enrollment; however, HRD testing still needs to be performed.

  4. Participants must have histologically diagnosed, relapsed, high-grade (Grade 2 or 3) serous epithelial ovarian, fallopian tube, or primary peritoneal cancer with recurrent disease and must have been previously treated with chemotherapy and have not experienced disease progression at least 6 months to the last chemotherapy containing platinum-based anticancer agents.
  5. Participants must have completed 3 or 4 previous chemotherapy regimens. Participants must have completed their last chemotherapy regimen >4 weeks prior to treatment initiation.
  6. Participants must have at least one measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) (v.1.1).
  7. Participants must have performance status of ≤1 on the Eastern Cooperative Oncology Group (ECOG) Performance Status Scale.

    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5×ULN unless liver metastases were present, in which case they had to be ≤5×ULN.
  9. Participants must have formalin-fixed, paraffin-embedded tumor samples available from the primary or recurrent cancer or agree to undergo fresh biopsy prior to study treatment initiation.
  10. Participants must be able to take oral medications.
  11. Female participants of childbearing potential must be negative for pregnancy test (beta-human chorionic gonadotropin [β-hCG]) within 7 days prior to receiving the first dose of study treatment.

  12. Female participants who:

    • Are postmenopausal for at least 1 year before the screening visit, OR
    • Are surgically sterile, OR
    • If they are of childbearing potential, agree to practice 1 highly effective method of contraception and 1 additional effective (barrier) method at the same time, from the time of signing the informed consent through 180 days after the last dose of study drug, OR
    • Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence [eg, calendar, ovulation, symptothermal, postovulation methods], condoms only, withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.)

  4. Participants who have received pelvic radiotherapy as treatment for primary or recurrent disease within 1 year of the first dose of study treatment.

  5. Participants who have symptomatic, uncontrolled brain or leptomeningeal metastases.

    To be considered "controlled," central nervous system (CNS) disease must have undergone treatment (eg, radiation or chemotherapy) at least 1 month prior to study enrollment. The participant must not have had any new or progressive signs or symptoms related to the CNS disease and must have been taking a stable dose of steroids or no steroids (as long as these were started at least 4 weeks prior to enrollment] or no steroids). A scan to confirm the absence of brain metastases at baseline was not required.

  13. Participants who have received a live virus or bacterial vaccines within 4 weeks of the first dose of study treatment.
  14. Participants who have a history or current evidence of any condition, therapy, or lab abnormality (including active or uncontrolled myelosuppression [ie, anemia, leukopenia, neutropenia, thrombocytopenia]) that might confound the results of the study, interfere with the participant's participation throughout the study period, or study participation is not in the best interest of the participant.
  15. Participants who are regular user (including "recreational use") of any illicit drugs at the time of signing informed consent or have a recent history (within the past year) of drug or alcohol abuse.

  16. Participants who are pregnant or breast-feeding or expecting to conceive within the planned duration of the study.
