Registration Number
NCT03759587
Lead Sponsor
Takeda
Brief Summary

The purpose of this study is to evaluate the safety and efficacy of niraparib in Japanese participants with platinum-sensitive, relapsed ovarian cancer, fallopian tube cancer, or primary peritoneal cancer who achieved complete response (CR) or partial response (PR) in the last chemotherapy containing platinum-based anticancer agents.

Detailed Description

The drug being tested in this study is called niraparib. Niraparib is being tested to treat people who have platinum-sensitive, relapsed ovarian cancer, fallopian tube cancer, or primary peritoneal cancer. This study will look at the safety and efficacy of niraparib in Japanese participants.

The study will enroll approximately 15 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 28 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.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Grade 3 or 4 Thrombocytopenia Occurring Within 30 Days After Initial Administration of NiraparibUp to 30 days after the first dose

An adverse event of 'thrombocytopenia' was collected and graded as per the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4.03.As per the 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 Adverse Events (AE).

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)From the day of signing the informed consent form (ICF) until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An AE is 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 is defined as an adverse event with an onset that occurs after receiving study drug.

Number of Participants With Grade 3 or Higher TEAEsFrom the day of signing the ICF until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An AE is 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 is defined as an adverse event with an onset that occurs after receiving study drug. A severity grade is defined by the 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.

Number of Participants With Serious Adverse Events (SAEs)From the day of signing the ICF until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An SAE is 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.

Number of Participants With TEAEs Leading to Drug DiscontinuationFrom the day of signing the ICF until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An AE is 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 is defined as an adverse event with an onset that occurs after receiving study drug.

Number of Participants With TEAEs Leading to Dose InterruptionFrom the day of signing the ICF until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An AE is 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 is defined as an adverse event with an onset that occurs after receiving study drug.

Number of Participants With TEAEs Leading to Dose ReductionFrom the day of signing the ICF until 30 days after last dose of study drug administration or beginning of subsequent anticancer therapy, whichever comes first (up to 48 months).

An AE is 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 is defined as an adverse event with an onset that occurs after receiving study drug.

Progression Free Survival (PFS)From first study drug administration until disease progression or death (up to 48 months)

PFS is defined as the time in months from the date of first study drug administration to the date of first documentation of progressive disease (PD) or death as assessed by the Investigator per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Per RECIST 1.1, PD is defined as at least a 20% increase in the SoD (Sum of Diameters) of target lesions, taking as a reference the smallest (nadir) SoD since (and including) baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 mm.

Overall Survival (OS)Up to 48 months

OS is defined as the time from the study enrollment to death due to any cause.

Overall Response Rate (ORR)Up to 48 months

ORR is defined as the proportion of participants achieving Complete Response (CR) or Partial Response (PR) as assessed by the investigator per RECIST (v.1.1). Per RECIST 1.1, CR is defined as disappearance of all target lesions; PR is defined as atleast 30% decrease in sum of diameters (SoD) of target lesions.
