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.

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.

Arms:
arm 1: Niraparib 300 milligrams (mg), capsules, orally, once daily on Days 1 to 28 of each 28-day treatment cycle for up to 50 cycles.

Interventions: intervention 1: Niraparib
Intervention descriptions: intervention 1: Niraparib capsule

STUDY SUMMARY
Name of Sponsor(s):
Takeda Pharmaceutical Company, Ltd.
Compound:
Niraparib (MK-4827)
Title of Protocol:
A phase 2 multicenter, open-label, single-arm study to 
evaluate the safety and efficacy of niraparib in Japanese 
patients with advanced, relapsed, high-grade serous 
epithelial ovarian, fallopian tube, or primary peritoneal 
cancer who have received 3 or 4 previous chemotherapy 
regimens
EudraCT No.:
Not Applicable
Study Number: Niraparib-2002
Phase: 2
Study Design:
This study is a phase 2, multicenter, open-label, single-arm study to evaluate the safety and efficacy of niraparib in the 
homologous recombination deficiency (HRD)-positive Japanese patients with advanced, relapsed, high-grade serous 
epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received 3 or 4 previous chemotherapy 
regimens.
The eligible patients must have received 3 or 4 previous chemotherapy regimens. The study will assess efficacy of 
niraparib by ORR whether treatment with niraparib will benefit HRD positive patients who received 3 or 4 prior 
anti-cancer therapies and are platinum-sensitive (with a continued response of at least 6 months from the last date of 
the treatment) to the last platinum-based therapy. The safety of niraparib will also be assessed in Japanese patients who 
received 3 or 4 prior anti-cancer therapies and are platinum-sensitive to the last platinum- based therapy.
In order to determine eligibility, a tumor sample will be tested for HRD testing. Patients must wait for the results from 
the on-study HRD testing provided by the central laboratory prior to enrollment, unless they have previously detected 
gBRCA mutation. If gBRCAmut is detected by a prior gBRCAmut testing, then it is not necessary to wait for HRD
testing results for enrollment into the study, however confirmatory central HRD testing still needs to be performed.
Eligible subjects will receive 300 mg/day of the study drug orally QD continuously (in 28-day cycles), and the 
treatment will continue until the patient meet a discontinuation criteria specified in the study protocol.
Dose interruption (no longer than 28 days) and dose reductions (maximum reduction to 100 mg/day) will be allowed. 
Dose interruption and/or reduction may be implemented at any time for any grade toxicity considered intolerable by 
the patient. The timing of efficacy or safety evaluations should not be affected by dose interruptions or reductions.
Clinic visits will be weekly during Cycle 1 and then every 4 weeks (±3 days) for subsequent cycles.
Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used for tumor assessment via a 
computed tomography (CT) or magnetic resonance imaging (MRI) scan of abdomen/pelvis and clinically indicated 
areas, which is required at the end of every 2 cycles (8 weeks with a window of ±7 days from date of visit) through 6 
months (ie, Cycle 6), then at the end of every 3 cycles (12 weeks with a window of ±7 days) until Cycle 39, and at the 
end of every 6 cycles (24 weeks with a window of ±7 days) until progression. Copies of scans will be collected for 
future central evaluation if needed. Cycle timing will not be delayed for treatment interruptions, and tumor assessment 
should occur according to this schedule regardless of whether study treatment is interrupted.
All AEs will be collected and recorded for each patient from the day of signing the informed consent form (ICF) until 
30 days after last dose of study treatment administration, or beginning of subsequent anticancer therapy, whichever 
comes first. All AEs and SAEs experienced by a patient, irrespective of the suspected causality, will be monitored 
until the AE or SAE has resolved, any abnormal laboratory values have returned to baseline or normalized, until there 
is a satisfactory explanation for the changes observed, until the patient is lost to follow-up, or until the patient has died. 
The Adverse Events of Special Interest (AESIs) for this study are MDS, AML, secondary cancers (new primary 
malignancies other than MDS/AML), pneumonitis, and embryo-fetal toxicity. AESIs must be reported to the Sponsor 
as soon as the investigator becomes aware of them.

Blood samples for measurements of plasma levels of niraparib will be obtained on Cycle 1 Day 1 predose and 2 hours 
postdose, Cycle 2 Day 1 predose and 2 hours postdose, and Cycle 4 Day 1 predose.
Primary Objectives:
To evaluate the efficacy of niraparib in HRD-positive Japanese patients with advanced, relapsed, high-grade serous 
epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received 3 or 4 prior lines of anti-cancer 
therapy and are platinum-sensitive to the last platinum-based therapy.
Secondary Objectives:
To evaluate the safety of niraparib in HRD-positive Japanese patients with advanced, relapsed, high- grade serous 
epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received 3 or 4 prior lines of anti-cancer 
therapy and are platinum-sensitive to the last platinum-based therapy.
Subject Population: Japanese adult patients with HRD-positive, advanced, relapsed, high- grade serous epithelial 
ovarian, fallopian tube, or primary peritoneal cancer, who have received 3 or 4 prior lines of anti-cancer therapy.
Number of Subjects:
16 subjects
Number of Sites:
Approximately 30 sites in Japan
Dose Level(s):
The study drug will be administered at 300 mg QD, orally,
continuously, in 28-day cycles., and the treatment will 
continue until the patient meet a discontinuation criteria
specified in the study protocol.
Route of Administration:
Oral
Duration of Treatment: Subjects may receive study drug 
until they experience objective PD, experience 
unacceptable toxicity, withdrawal of consent or until study 
discontinuation due to any other reasons specified in the 
study protocol.
Period of Evaluation: The estimated time frame for 
study completion (screening, study drug administration 
and follow-up period) is approximately 26 months.
Main Criteria for Inclusion:
1.
Japanese female patients 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 patient at any time without prejudice
to future medical care.
3.
Patients must agree to undergo tumor HRD testing, and this test result must show that patients 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 patient is likely to meet other eligibility requirements.
Note 2: If historic blood 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.
Patients 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.

INTRODUCTION
4.1 
Background
Niraparib is an orally available, potent, and highly selective PARP1 and PARP2 inhibitor. 
Niraparib was originated by Merck and developed by TESARO for the treatment of a variety of 
cancer types.
DNA repair is accomplished by serval mechanisms in healthy cells including, but not limited to, 
homologous recombination, base excision repair, and nonhomologous end-joining. Some cells are 
incapable of homologous recombination due to the inactivation of genes such as BRCA1, BRCA2, 
ataxia telangiectasia mutated (ATM), and others. In the absence of homologous recombination, 
these cells must rely on alternative DNA repair mechanisms.
A complete loss of function or inactivation of both BRCA alleles occurs commonly in women who 
are carriers of a gBRCAmut. A loss of BRCA function compromises the repair of double-strand 
DNA breaks via the homologous recombination pathway resulting in the use of an alternative 
DNA repair pathway such as NHEJ. Reliance on mechanisms such as NHEJ contributes 
significantly to the accumulation of mutations in ovarian cells and may ultimately promote the 
development of ovarian tumors.[1][2]
PARP1 and PARP2 are zinc-finger DNA-binding proteins that detect damaged DNA and promote 
DNA repair by several mechanisms. After detecting DNA damage, PARP activates the BER 
pathway via an intracellular signaling mechanism. Conversely, PARP inhibitors block DNA repair 
by the BER pathway. In cells incapable of DNA repair via homologous recombination (eg, BRCA1 
and BRCA2 mutations), PARP inhibition leads to irreparable DSB, collapsed replication forks, and 
an increased use of the NHEJ pathway. These disruptions result in genomic instability and 
ultimately cell death. The synergy between cellular defect and drug-induced effect is referred to as 
synthetic lethality.[3] Treatment with PARP inhibitors represents an opportunity to selectively kill 
cancer cells with deficiencies in homologous recombination and other DNA repair mechanisms. 
Recently, it has been reported that, breast cancer gene (BRCA) mutation-negative, wild-type 
tumors, can result in a BRCA1/2 mutation-like state as a result of deficiency in repair of DNA 
double-strand breaks by homologous recombination due to other factors. It is anticipated that 
PARP inhibitors may induce synthetic lethality against such tumor.[4] In ovarian cancer, the 
homologous recombination deficiency (HRD) score has been found useful as an indicator of HRD, 
including such genomic instability.[5]
Based on the results of a TESARO-sponsored overseas phase 3 pivotal study (NOVA study), 
niraparib has been approved in the in March 2017 and in Europe in November 2017, as a 
maintenance therapy for adult patients with relapsed epithelial ovarian, fallopian tube, or primary 
peritoneal cancer who achieved CR or PR to a chemotherapy containing platinum-based 
anticancer agents.
Nonclinical and clinical study result summaries are shown below. For further details, refer to the 
current Investigator’s Brochure and package inserts in regions/countries where niraparib is 
approved.

4.1.1 Nonclinical Studies
In animal models, maximal in vivo efficacy was achieved in mutant breast cancer susceptibility 
gene (BRCA) 1 (BRCA1mut) ovarian tumor models with once daily (QD) oral administration of 
niraparib at a dose sufficient to suppress approximately 90% of the PARP-enzymatic activity in 
the tumor at 8 hours postdose. The same dose translated to a >50% inhibition of PARP activity in 
peripheral blood mononuclear cells (PBMCs) at 8 hours postdose.
Data from nonclinical experiments demonstrate that tumors containing BRCA mutations or that are 
otherwise positive by commercially available homologous recombination deficiency (HRD) tests 
regressed in response to niraparib treatment. Moreover, tumor growth inhibition was observed in a 
subset of HRD-negative (HRDneg) models, suggesting that there is a gradient of response to 
niraparib that is observed on a population basis by use of different biomarkers.
4.1.2 Clinical Studies
Niraparib clinical studies have been conducted in Japan and overseas countries, and the safety and 
tolerability of niraparib has been evaluated in over 1214 patients with advanced cancer who have 
received at least 1 dose of niraparib. The highest dose studied in the overseas Phase 1 trials was 
400 mg QD, and the dose-limiting toxicity at this dose was thrombocytopenia. The recommended 
phase 2 dose for niraparib monotherapy was 300 mg QD, and this dose was subsequently approved 
for the treatment of ovarian cancer (OC) in the United States (US) and European Union (EU), 
based on the result of overseas phase 3 study. In addition, based on the results of Study
PR-30-5020-C (QUADRA study), an overseas phase 2 study of niraparib in patients with 
advanced, relapsed, high-grade serous epithelial OC who have received three or more lines of 
chemotherapy regimens, TESARO is planning to apply for additional indication of niraparib in the 
U.S. within this year.
4.1.2.1 Study PR-30-5020-C (QUADRA) (Overseas Phase 2)
This study is a phase 2, multicenter, open-label, single-arm study to evaluate the safety and 
efficacy of niraparib in patients with advanced, relapsed, high-grade serous epithelial ovarian, 
fallopian tube, or primary peritoneal cancer who have received three or four previous 
chemotherapy regimens. Niraparib 300 mg was administered orally once daily continuously 
beginning on Day 1 and every cycle (28 days) thereafter until the patient the patient met a 
discontinuation criteria specified in the study protocol.
At the time of study initiation, patients must have completed at least 3 previous lines of plat inum 
containing therapy (regardless of platinum sensitivity) and agreed that they would receive HRD 
and gBRCA test. Later, the study protocol has been revised to intensively enroll patients with 
HRD-positive tumor. The HRD-positive subjects were determined in advance based on the results 
of MyChoice®HRD analysis (Myriad Genetics, U.S.) (hereinafter referred to as "Myriad").

In this study, the initial dose of niraparib is determined as 300 mg, based on the maximum dose at 
which tolerability was observed in Japanese patients. Given the overseas clinical data indicated 
that the patient body weight can affect the occurrence of study drug-related TEAEs, it is important 
to examine the safety of niraparib in Japanese patients because the body weight of Japanese 
patients is generally lower than that of patients in US or EU.

STUDY DESIGN
6.1 
Overview of Study Design
This study is a phase 2, multicenter, open-label, single-arm study to evaluate the safety and 
efficacy of niraparib in patients with advanced, relapsed, high-grade serous epithelial ovarian, 
fallopian tube, or primary peritoneal cancer who have received 3 or 4 previous chemotherapy 
regimens.
Patients must have received 3 or 4 previous chemotherapy regimens. The study will assess by 
ORR whether treatment with niraparib will benefit HRD positive patients who received 3 or 4 
prior anti-cancer therapies and are platinum-sensitive to the last platinum-based therapy. The 
safety of niraparib will also be assessed in Japanese patients who received 3 or 4 prior anti-cancer 
therapies and are platinum-sensitive to the last platinum- based therapy.
In order to determine eligibility, a tumor sample will be tested for HRD testing. Archival or fresh 
tissue is required in order to enroll in the study. The sample may be tested in advance of the 
protocol-defined screening period (ie, within 40 days before Cycle 1 Day 1) if the consent has been 
obtained, in order to facilitate the screening and enrollment process. Patients must wait for the 
results from the on-study HRD testing provided by the central laboratory prior to enrollment, 
unless they have previously detected gBRCA mutation. If gBRCAmut is detected by a prior 
gBRCAmut testing, then it is not necessary to wait for HRD testing results for enrollment into the 
study, however confirmatory HRD testing still needs to be performed.
Eligible subjects will receive 300 mg/day of the study drug orally QD continuously (in 28-day 
cycles) and the treatment will continue until the patient meet a discontinuation criteria specified in 
the study protocol.
Dose interruption (no longer than 28 days) and dose reductions (maximum reduction to 
100 mg/day) will be allowed. Dose interruption and/or reduction may be implemented at any time 
for any grade toxicity considered intolerable by the patient. The timing of efficacy or safety 
evaluations should not be affected by dose interruptions or reductions.
Clinic visits will be weekly during Cycle 1 and then every 4 weeks (±3 days) for subsequent 
cycles. Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used for tumor 
assessment via a computed tomography (CT) or magnetic resonance imaging (MRI) scan of 
abdomen/pelvis and clinically indicated areas, which is required at the end of every 2 cycles (8 
weeks with a window of ±7 days from date of visit) through 6 months (ie, Cycle 6), then at the end 
of every 3 cycles (12 weeks with a window of ±7 days) until Cycle 39, and at the end of every 6 
cycles (24 weeks with a window of ±7 days) until progression. Copies of scans will be collected 
for future central evaluation if needed. Cycle timing will not be delayed for treatment 
interruptions, and tumor assessment should occur according to this schedule regardless of whether 
study treatment is interrupted.
All AEs will be collected and recorded for each patient from the day of signing the informed 
consent form (ICF) until 30 days after last dose of study treatment administration, or beginning of

subsequent anticancer therapy, whichever comes first. All AEs and SAEs experienced by a patient, 
irrespective of the suspected causality, will be monitored until the AE or SAE has resolved, any 
abnormal laboratory values have returned to baseline or normalized, until there is a satisfactory 
explanation for the changes observed, until the patient is lost to follow-up, or until the patient has 
died. The Adverse Events of Special Interest (AESIs) for this study are MDS, AML, secondary 
cancers (new primary malignancies other than MDS/AML), pneumonitis, and embryo -fetal 
toxicity. AESIs must be reported to the Sponsor as soon as the investigator becomes aware of 
them.
Blood samples for measurements of plasma levels of niraparib will be obtained on Cycle 1 Day 1 
predose and 2 hours postdose, Cycle 2 Day 1 predose and 2 hours postdose, and Cycle 4 Day 1 
predose.
6.2 
Number of Patients
Approximately 16 patients will be enrolled in this study from approximately 30 study centers in 
Japan. Enrollment is defined as the time when the sponsor sends an enrollment sheet back to the 
investigational site (see Section 9.4.12).
6.3 
Duration of Study
6.3.1 Duration of an Individual Patient’s Study Participation
Patients may receive study drug until they experience PD, unacceptable toxicity, withdrawal of 
consent, or for any of the other reasons outlined in Section 9.8. The OS follow-up should be 
performed until any of reason for withdrawal of patients from study (described in Section 9.9) 
including death occur.
6.3.2 End of Study/Study Completion Definition and Planned Reporting
End of study is defined as a date that last patient complete post treatment assessments.
Primary Analysis

STUDY DRUG
8.1 
Study Drug Administration
The study drug will be administered at 300 mg QD, orally, continuously, in 28-day cycles. 
Niraparib will be administered until subjects experience objective PD, experience unacceptable 
toxicity, withdrawal of consent or until study discontinuation due to any other reasons specified in 
the study protocol.
The study drug should be administered at approximately the same time every day. In the event of 
missed doses or vomited doses, the dose will not be re-administered. The study drug should not be 
chewed before swallowing. The study drug may be taken with water.
Patients will be provided dosing diary and instructed to record any dose of study drug and the time 
of administration in their dosing diary in study treatment period.
8.2 
Dose Modification Guidelines
8.2.1 Criteria for Dose Reduction, Interruption, and Discontinuation
Dose interruption and/or reduction may be implemented at any time for any grade toxicity if the 
investigator or subinvestigator deems that the toxicity is intolerable by the patient.
All dose interruptions and reductions (including any missed doses), and the reasons for the 
reductions/interruptions, are to be recorded in the electronic case report from (eCRF).
(1) Dose Modifications for Non-Hematologic Toxicities
Treatment must be interrupted for any NCI CTCAE (v.4.03) Grade 3 or 4 non-hematologic 
toxicity which the investigator or subinvestigator considers to be related to administration of 
niraparib. If the Grade 3 or 4 non-hematologic toxicity is appropriately resolved to baseline or 
Grade 1 or less within 28 days following interruption, the patient may restart treatment with 
niraparib at the same dose level. However, if prophylaxis is not considered feasible, treatment with 
niraparib should be restarted with a dose level reduction according to Table 8.a. After the restart, if 
the event recurs at the same or worse grade, treatment should be interrupted again and, upon 
resolution, treatment with niraparib should be restarted with a dose level reduction according to 
Table 8.a.
Dose reductions to 200 mg/day and subsequently to 100 mg/day will be allowed. No further dose 
reduction will be allowed. If the toxicity requiring dose interruption has not resolved completely or 
to NCI CTCAE Grade 1 during the maximum 4-week (28-day) dose interruption period, and/or the 
patient has already undergone the maximum dose reductions, the patient must permanently 
discontinue study treatment.

(a) Dose not to be decreased below 100 mg QD.
(2) Dose Modification for Hematologic Toxicities
The dose interruption/modification criteria for hematologic parameters will be based on blood 
counts and are outlined in Table 8.b.
If the hematologic toxicity has not recovered to the specified levels within 4 weeks (28 days) of the 
dose interruption period, and/or the patient has already undergone a maximum reduction(s), the 
patient must permanently discontinue treatment with niraparib.
Table 8.b
Dose Interruption, Resume or Reduction for Hematologic Toxicities
Finding
Modification
Platelet count 75,000-99,999/μL
(1st occurrence)
Study medications must be interrupted until platelet counts are ≥100,000/μL, 
with weekly blood counts for CBC monitored until recovery. Study medication 
may then be resumed at same dose or reduced dose based on clinical judgment.
Platelet count 75,000-99,999/μL
(2nd occurrence after resolution)
Study medications must be interrupted until platelet counts are ≥100,000/μL, 
with weekly blood counts for CBC monitored until recovery. Study medication 
may then be resumed at a reduced dose.
Platelet count <75,000/μL*
Study medications must be interrupted until platelet counts are ≥100,000/μL, 
with weekly blood counts for CBC monitored until recovery. Study medication 
may then be resumed at a reduced dose.
Neutrophil <1,000/μL
Study medications must be interrupted until neutrophil counts ≥1,500/μL, with 
weekly blood counts for CBC monitored until recovery. Study medication may 
then be resumed at a reduced dose.
Hemoglobin <8 g/dL
Study medications must be interrupted until hemoglobin is ≥9 g/dL, with weekly 
blood counts for CBC monitored until recovery. Study medication may then be 
resumed at a reduced dose.
CBC: complete blood cell count.
*For patients with platelet count ≤10,000/μL prophylactic platelet transfusion per guidelines may be considered. For 
patients taking anticoagulation or antiplatelet drugs consider of interrupting these drugs and/or prophylactic 
transfusion at an alternate threshold, such as ≤20,000/μL (before platelet count decreased ≤10,000/μL).
If dose interruption or modification is required at any point on study because of hematologic 
toxicity, weekly blood draws for CBC will be monitored until the AE resolves. When the treatment 
is re-started after the AE resolution, weekly blood draws for CBC will be also required for an

additional 4 weeks to ensure safety of the restarted dose. Monitoring every 4 weeks may resume
thereafter.
Any patient requiring transfusion of platelets or red blood cells (1 or more units) or hematopoietic
growth factor support must undergo a dose reduction upon recovery if study treatment is resumed.
The patient must be referred to a hematologist for further evaluation (1) if transfusions are required
on 1 or more occasions or (2) if the treatment-related hematologic toxicities have not recovered to
NCI CTCAE Grade 1 or less after 4 weeks interruption with sufficient supportive care. If a 
diagnosis of myelodysplastic syndrome (MDS)/acute myeloblastic leukemia (AML) is confirmed 
by a hematologist, the patient must permanently discontinue study treatment.
(3) Other
If a secondary cancer (new malignancies other than MDS/AML) is diagnosed while on study, the 
patient must permanently discontinue study treatment.
For major surgery while on treatment, up to 28 days of drug interruption is allowed.
Re-Escalation After Dose Reduction
8.2.2
Once the dose of study treatment has been reduced, any re-escalation must be discussed with the
medical monitor.
Criteria for Beginning or Delaying a Subsequent Treatment Cycle
8.2.3
Niraparib will be administered in continuous cycles; therefore, study drug should be administered
continuously unless TEAEs occur that meet the dose modification criteria outlined in 
Section 8.2.1.
If dose interruption was required due to TEAE at the beginning of a Cycle, the Cycle should not be
postponed. Once the patient recovers from the TEAE, the study treatment will be resumed in the
middle of the cycle, without waiting for the first day of the next Cycle.
However, the timing of efficacy and safety evaluations will not be affected by the dose interruption
or dose reduction.
8.3
Excluded Concomitant Medications and Procedures
The following medications, procedures and foods are prohibited from 4 weeks prior to the first 
administration of study drug through the treatment discontinuation visit:

Other anticancer therapies other than study treatment, with the exception as follows:
–
The patient can receive a stable dose of corticosteroids during the study as long as these
were started at least 4 weeks prior to enrollment for the treatment of brain or
leptomeningeal metastases or other diseases (Section 7.2, Exclusion Criteria 5).
Temporary steroid use will be permitted for treatment of AEs or for prophylaxis. Of note,

topical steroids such as intraarticular, intranasal, eye-drops, and inhalation are permitted 
without limitation.
–
Palliative radiotherapy (except pelvis and/or palliative radiotherapy encompassing >20%
of the bone marrow within 1 week of the first dose of study treatment) is allowed for
pre-existing small areas of painful metastases that cannot be managed with local or
systemic analgesics as long as no evidence of PD is present.

Conventional chemotherapy drugs, live virus and bacterial vaccines increased risk of infection
have been observed. Effects with niraparib are unknown and therefore they should not be
administered to patients 4 weeks before initial administration of niraparib and during the study.

Prophylactic cytokine (granulocyte colony-stimulating factor [GCSF]) administration should
not be given in Cycle 1. Prophylactic cytokine may be administered in Cycle 2 onwards
according to local guidelines, etc.
The following medications, procedures, and foods should be used with caution during the study
treatment period:

Drugs that are substrates for cytochrome P450 (CYP) 1A2 (Appendix F) (niraparib is a
CYP1A2 inducer).

Drugs that are inhibitors or substrates for P-glycoprotein (P-gp) (niraparib is a substrate for
P-gp).

Anticoagulation and antiplatelet drugs (niraparib potential risk includes thrombocytopenia).

Drugs associated with QT interval (QTc) prolongation (Appendix G) (Niraparib has been
associated with QT prolongation when co-administered with medications known to cause QTc
prolongation.)


If they are of childbearing potential*, agree to practice 1 highly effective method and 1
additional effective (barrier) method of contraception** at the same time, from the time of
signing of the ICF through 180 days after the last dose of study drug, or

Agree to practice true abstinence from the time of signing of the ICF through 180 days after the
last dose of study drug, when this is in line with the preferred and usual lifestyle of the subject.
(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.)
*Women of childbearing potential are defined as any sexually active female subjects who meet
both of the following criteria:

Those who have not undergone hysterectomy or bilateral oophorectomy.

Those who have not had natural menopause for 12 consecutive months or longer.
Note: A postmenopausal state is defined as no menses for 12 months without an alternative
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range
may be used to confirm a postmenopausal state in women not using hormonal contraception or
hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single
FSH measurement is insufficient.
**Examples of highly effective contraception methods are listed below:

Hormonal birth control pills.

Intrauterine device.

Intrauterine hormone-releasing system.

Informed Consent
9.4.1
Each patient must provide written informed consent before any study-required procedures are 
conducted, unless those procedures are performed as part of the patient’s standard care.
Patient Demographics
9.4.2
The date of birth, race and sex of each subject are to be recorded during the Screening period. If
available, the data on whether individual subjects have BRCA mutations will also be collected.
Medical History
9.4.3
During the Screening period, all concurrent conditions will be collected for each subject. Also,
medical histories that are considered to be clinically useful by the investigator will be collected.
As the information about the underlying disease, the following data will be collected and recorded
specifically: the date of initial diagnosis, the type of tumor, the stage of disease at the initial
diagnosis, the results of histology at diagnosis and grade.
During screening, the following medications are to be recorded as prior medications based on
hearing from the subjects:


and end dates and the best response to each treatment.

All prior surgeries for the underlying disease.
9.4.4 Collection of Tumor Sample for HRD Test
A tumor sample (archival or fresh tissue) will be collected and tested by a centralized laboratory 
for HRD testing before initial administration of study drug. Patients must wait for the results from 
the on-study centralized HRD testing provided by the central laboratory prior to enrollment, unless 
they have previously detected gBRCA mutation. If gBRCAmut is detected by a prior gBRCAmut 
testing, then it is not necessary to wait for HRD testing results for enrollment into the study, 
however confirmatory HRD testing still needs to be performed. Sites are encouraged to send tumor 
samples for HRD testing as soon as a consent is obtained from patient. Archival or fresh tissue is 
required to send immediately after the consent is obtained in order to enroll in the study. The 
sample may be tested in advance of the protocol-defined screening period (ie, within 40 days 
before Cycle 1 Day 1) if the consent has been obtained, in order to facilitate the screening and 
enrollment process. Remaining tumor samples, if available, will be stored and may be used at a 
later time for development of new HRD test. It is optional whether the patients will provide their 
remaining specimens for the development of new HDS test.
If possible, additional tumor samples (archival or fresh tissue) will be collected and stored, and 
may be used at a later time for development of new HRD test.
Details on tissue sample collection can be found in the Laboratory Manual.
9.4.5 Physical Examination
A physical examination will be completed per standard of care at the times specified in the 
Schedule of Events (Appendix A).
9.4.6 Patient Height
Height will be measured at screening only. Weight will be measured at the times specified in the 
Schedule of Events (Appendix A).
9.4.7 Vital Signs
Vital signs include diastolic and systolic blood pressure, pulse rate and body temperature (axillary) 
measured at the times specified in the Schedule of Events (Appendix A). Subjects must be resting 
in a sitting position for 10 minutes prior to obtaining vital signs. This measurement method will be 
used throughout the study. To determine the effects of niraparib on the cardiovascular system, 
blood pressure will be measured prior to obtaining blood samples.
If blood pressure exceeds 150/100 mmHg or diastolic blood pressure exceeds 20 mmHg from 
baseline despite the subject has no history of hypertension, blood pressure must be re -measured 
within 10 minutes for confirmation.

If there was a change in blood pressure from prior to study drug administration, which was judged 
by the investigator as an AE, such change will be recorded in the eCRF.
9.4.8 ECOG Performance Status
ECOG performance status will be assessed and recorded according to (Appendix E) at the times 
specified in the Schedule of Events (Appendix A).
The investigator will evaluate the performance status.
9.4.9 Pregnancy Test
A serum pregnancy test will be performed for women of childbearing potential (defined in 
Section 8.5.1) within 7 days before Cycle 1 Day 1, and negative results must be obtained before 
the first dose of study drug. Subsequently, serum or urine pregnancy tests will be performed every 
three cycles during the study treatment, and negative results must be obtained before the study 
drug administration.
9.4.10 Concomitant Medications and Procedures
Medications used by the subject and therapeutic procedures completed by the subject will be 
recorded in the eCRF from the time of signing the informed consent through 30 days after the last 
dose of study drug or the start of subsequent antitumor therapy, whichever comes first. See 
Section 8.3 and Section 8.4 for medications and therapies that are prohibited or allowed during the 
study.
All medications other than the study drug (including Chinese herbal medicine and other
non-traditional remedies) and treatment used by subjects during the study period should be 
investigated and recorded by hearing from the subjects. For each medication, the nonproprietary 
name, the start and end date and the purpose of use will be recorded.
9.4.11 Adverse Events
Monitoring of AEs, serious and nonserious, will be conducted throughout the study as specified in 
the Schedule of Events (Appendix A). Refer to Section 10.0 for details regarding definitions, 
documentation, and reporting of AEs and serious AEs (SAEs).
For any suspected case of MDS/AML or second primary malignancies other than MDS/AML 
reported while a patient is receiving treatment or being followed for post -treatment assessments, 
bone marrow aspirate and biopsy testing must be completed by a local hematologist. Testing 
completed as part of standard of care is sufficient as long as the methods are acceptable to the 
Sponsor's Medical Monitor. The study site must receive a copy of the hematologist’s report of 
aspirate/biopsy findings, which must include a classification according to World Health 
Organization (WHO) criteria, and other sample testing reports related to MDS/AML or secondary 
cancer (new malignancies other than MDS/AML).

9.4.14.2 Serum CA-125 Assessment
Blood samples for analysis of the serum CA-125 assessment will be obtained on the same day, 
before administration of the study drug, as specified in the Schedule of Events (Appendix A).
If CA-125 samples for screening assessment are collected within 72 hours prior to the first dose on 
Cycle 1 Day 1, repeat testing is not required for Cycle 1 Day 1.
9.4.15 Disease Assessment
Subjects will undergo computed tomography (CT) with contrast as appropriate to monitor and 
assess PD, using modified RECIST criteria (Version 1.1) (Appendix E). Specific disease sites that 
cannot be adequately imaged by CT with contrast may be documented by magnetic resonance 
imaging (MRI). Bone scans may be performed on subjects with bone metastases rather than 
contrast enhanced CT or MRI.
During the study, anatomical measurements will be collected for each target lesion using an 
imaging modality consistent with that used at Screening. The same method (CT with contrast, 
MRI or bone scan) must be consistently used on a subject throughout the study.
Objective assessments will be performed at each time point as described in the Schedule of Events 
(Appendix A). When possible, the same qualified physician will interpret the results to reduce 
variability.
Appropriate imaging evaluation at screening should include a CT/MRI of the chest, abdomen and 
pelvis. Imaging evaluations of other body parts are not necessary unless clinically indicated.
If the chest CT/MRI is clear at screening, repeat chest imaging is not required in the absence of 
lesions to be followed or in the absence of clinical indication requiring follow-up.
The sizes of visible lesions will be recorded using a ruler. The sizes of palpable lesions will be 
recorded in the subject's source documents at the physical examination. The tumor status will be

compared with that at screening, using physical findings, imaging results and ECOG performance 
status.
In this study, confirmation of complete or partial response is required. Complete or partial 
responses may be claimed only if the criteria for each are met 4 weeks or more later.
Radiographic images will be maintained at each site, and test results and physicians’ findings will 
be filed in subject's source documents. The sponsor may request electronic images for those 
subjects who demonstrate tumor reduction.
ORR
9.4.16
ORR is defined as the proportion of patients achieving complete response CR or PR as assessed by 
the investigator per RECIST (v.1.1) (Appendix E).
DOR
9.4.17
DOR is measured from the time measurement criteria are met for CR or PR (whichever is first 
recorded) until the first date that recurrent or progressive disease is objectively documented 
(taking as reference for progressive disease the smallest measurements recorded since the 
treatment started).
DCR
9.4.18
DCR is defined as the proportion of patients achieving CR, PR, or stable disease (SD) as assessed 
by the investigator per RECIST (v.1.1) (Appendix E).
PFS (Definition of PD)
9.4.19
PFS is defined as the time from the date of first dose to the earlier date of progression assessed by 
the investigator per RECIST (v.1.1) (Appendix E) or clinical criteria, or death by any cause.
PFS will be determined based on a tumor assessment by the investigator and the criteria of CA-125 
progression. The date of progressive disease (PD) will be determined based on imaging 
assessment according to RECIST v.1.1 (Appendix E) criteria, preferentially. Because of the pelvic 
location of the primary tumor and the frequent occurrence of peritoneal disease, imaging may not 
always be reliable for documentation of PD.
Criteria other than RECIST may be applicable to define PD. PD will be determined if at least 1 of 
the following criteria is met:
1. Tumor assessment by CT/MRI unequivocally shows PD according to RECIST v.1.1 criteria
(Appendix E).
a. If a patient had a CT/MRI of the abdomen/pelvis and clinically indicated areas within the
28-day screening window before Cycle 1 Day 1 but prior to signing the main ICF, the
patient is not required to complete an additional CT/MRI scan for study screening. CT/MRI
scans completed during screening prior to signing the ICF must have been performed under
same condition during the study and be able to be submitted.

2. Additional diagnostic tests (eg, histology/cytology, ultrasound techniques, endoscopy,
positron emission tomography) identify new lesions or determine existing lesions qualify for
unequivocal PD AND CA-125 progression according to Gynecologic Cancer Intergroup
(GCIG)-criteria (below).
3. Definitive clinical signs and symptoms of PD unrelated to non-malignant or iatrogenic causes
([1] intractable cancer-related pain; [2] malignant bowel obstruction/worsening dysfunction;
or [3] unequivocal symptomatic worsening of ascites or pleural effusion) AND CA-125
progression according to GCIG criteria (below).
PD will not be diagnosed in case of CA-125 progression in the absence of at least 1 of the criteria 
defined above.
The investigator will describe why PD was diagnosed in the eCRF. The date of PD is defined as 
the earliest time point when one of the PD criteria is met. When required to determine progression, 
CA-125 levels should be evaluated ±2 weeks from the primary PD assessments (ie, diagnostic test 
or clinical parameters) and must be confirmed by a second determination ≥7 days later. In case 
assessments of CA-125 levels occur greater than 2 weeks from the primary PD assessments, the 
date of the primary assessment of PD will be used to define the date of PD. GCIG criteria for 
CA-125 progression are as follows: (Note: CA-125 progression alone will not be considered 
disease progression.)
CA-125 progression according to GCIG criteria
1. Patients with elevated CA-125 pretreatment and normalization of CA-125 must show evidence
of CA-125 ≥2 x ULN on 2 occasions at least 1 week apart, OR
2. Patients with elevated CA-125 pretreatment, which never normalizes must show evidence of
CA-125 ≥2 x the nadir value on 2 occasions at least 1 week apart, OR
3. Patients with CA-125 in the normal range pretreatment must show evidence of CA-125 ≥2 x
ULN on 2 occasions at least 1 week apart.
If CT/MRI shows existing (baseline) lesions which only equivocally suggest PD and additional 
diagnostic tests are required to determine unequivocal PD, the official date of PD will be the date 
PD was unequivocally determined. Alternatively with new lesions (except ascites and effusions) 
that are initially equivocal that are later unequivocally determined, the date of progression will be 
the date the lesion was initially identified.
Note: If the investigator determines clinical PD, they can consult an imaging clinician at the 
investigational site prior to receiving results from the central reader. Pursuant to consultation with 
the clinician, the investigator can keep the patient on study treatment as long as it is considered 
safe, or the investigator can discontinue the patient.
9.4.20 OS
OS is defined as the time from the date of the first dose to the date of death by any cause. 
Following the treatment discontinuation visit, survival status will be collected for all patients using

acceptable means including telephone contact. New malignancy information will also be collected 
as part of this assessment.
Pharmacokinetic Measurements
9.4.21
Blood samples for PK analysis of niraparib will be serially collected at the time points specified in
the Schedule of Events (Appendix A). The exact dates and times of administration of niraparib 
before collection of the blood sample for PK analysis and the exact dates and times of collection of 
the blood sample for PK analysis will be recorded on the eCRF.
9.5
Records of Patients who Discontinued the Study After Enrollment and Before the 
First Administration of Study Drug
The investigator or subinvestigator is responsible for documenting the records of all patients who 
signed the ICF.
The investigator or subinvestigator is responsible for the eCRF data entry, even if the patient 
turned out to be ineligible after enrollment and before the first administration of study drug.
The primary reason of study discontinuation after enrollment and before the first administration of 
study drug will be recorded in the eCRF, under the following categories:

Death.

Adverse event.

Screen failure (the subject did not meet the inclusion criteria or did meet the exclusion criteria) .

Protocol deviation.

Lost to follow-up.

Consent withdrawal by patient.

Termination of the whole study by sponsor.
The subject identification number of the patient who discontinued the study before the first study 
drug administration will not be reused.
9.6 
Completion of Study Treatment (for Individual Patients)
Patients will be considered to have completed treatment if they discontinue treatment with study 
drug for any of the reasons outlined in Section 9.8.
Treatment will continue until PD, unacceptable toxicities, or withdrawal due to other reasons.
9.7 
Completion of Study (for Individual Patients)
Patients will be considered to have completed the study based on the patient being followed until a 
specific event, eg, death or until study termination, and complete the safety follow-up.


AE.
–
Any treatment-related NCI CTCAE (ver. 4.03) Grade 3 or 4 non-hematologic toxicity that
have not reverted to CTCAE Grade 1 or better within 28 days of dose interruption.
–
Any hematologic toxicity that have not retreated to the pre-specified level within 28 days
following study drug interruption.
–
Any treatment emergent adverse event that lead to study drug interruption and restart with
dose reduction occurred in a patient who has already received a minimum dose of niraparib
(100 mg QD) after prior study drug interruption due to adverse event.

Protocol deviation.

PD.


Other.
Once study drug has been discontinued, all study procedures outlined for the end-of-treatment visit 
will be completed as specified in the Schedule of Events (Appendix A). The primary reason for 
study drug discontinuation will be recorded on the eCRF.
Note that some patients may discontinue study drug for reasons other than progressive disease 
before completing the full treatment course; these patients will remain in the study for 
posttreatment assessments as outlined in the Schedule of Events until disease progression occurs.
9.9
Withdrawal of Patients From Study
A subject may be withdrawn from the study for any of the following reasons. However, subjects
may withdraw their consent to participate in the study at any time without prejudice.

The sponsor should be notified of all subject withdrawals from the study as soon as possible. If a 
subject withdraws consent to participate in the study, no study data will be collected or data added 
to the database for this subject thereafter. However, every effort will be made to follow all subjects 
for safety.
9.10 
Study Compliance
Study drug will be administered or dispensed only to eligible patients under the supervision of the 
investigator or identified subinvestigator(s). The appropriate study personnel will maintain records 
of study drug receipt and dispensing.
Subjects will receive a sufficient quantity of study drugs for each treatment cycle and provided a 
diary where the date of study drug administration will be recorded. The study site staff will check 
the patient diary versus the subject's supply of remaining niraparib at each study visit to ensure 
proper compliance with dosing. Subjects who are not compliant with the dosing schedule may be 
withdrawn from the study.
Tests and procedures should be performed on schedule. However, except Cycle 1 Day 1, Cycle 2 
Day 1, Early Termination and follow-up 30 days after the last dose, occasional changes are 
allowable within a 3-day window for holidays, vacations, and other administrative reasons. If 
extenuating circumstances prevent a subject from beginning treatment or completing a planned 
procedure or assessment within 3 days of the scheduled time, the subject may continue the study at 
the discretion of the investigator and after consultation with the sponsor's medical monitor or 
designee. However, the timing of PK assessment as specified in the Schedule of Events (Appendix 
A) is not flexible.
The observation and test specified in the Study Treatment Discontinuation visit will be conducted 
within 7 days after last dose of niraparib. The observation and test specified in the 30 days after the 
last dose visit will be conducted at 30 days (+7 days) after the last dose of study drug 
administration, or beginning of subsequent anticancer therapy, whichever comes first, and the 
follow-up assessments will be conducted every 90 days (±7 days) from the termination day of the 
study drug administration.
9.11 
Thirty Days Follow-up After the Last Dose
All AEs (including laboratory data specified in the schedule) and concomitant medications will be 
collected and recorded for each patient from the day of signing the ICF until 30 days (+7 days) 
after last dose of study treatment administration, or beginning of subsequent anticancer therapy, 
whichever comes first.
All AEs and SAEs which occurred until the visit of 30 days follow-up after the last dose will be 
recorded and monitored appropriately.

Posttreatment Follow-up Assessments (Progression-Free Survival and Overall 
Survival)
If a patient discontinues treatment for the reason other than PD, withdrawal by subject, and lost to 
follow-up, scans and CA-125 testing will continue to be collected for PFS evaluation.
The PFS evaluation after study treatment discontinuation will be performed at the protocol 
specified intervals (ie, same as an interval during study treatment) from study treatment 
discontinuation until progression is confirmed or until the start of subsequent anticancer treatment.
If a patient discontinues treatment for PD, follow-up information will continue to be collected for 
OS assessment. The OS assessment will be performed every 90 days (±7 days) following study 
treatment discontinuation. Following the treatment discontinuation visit, survival status will be 
collected for all patients using acceptable means (ie, hospital visit is not mandatory). New 
malignancy information will also be collected as part of this assessment.
The following information will be collected in the Post Treatment Assessments:

MDS, AML, and secondary cancers (new malignancies other than MDS/AML) which
occurred after study treatment discontinuation

Treatment-related death
–
The death must be reported by the investigator or subinvestigator to the Takeda Global
Pharmacovigilance Department or designee, same as during study treatment period
(Section 10.2).

Outcome of adverse event that occurred during the study
–
All AEs experienced by a patient will be monitored until the AE has resolved, any
abnormal laboratory values have returned to baseline or normal levels, until there is a
satisfactory explanation for the changes observed, until the patient is lost to follow-up, or
until the patient has died.

ADVERSE EVENTS
10.1
Definitions
AE Definition
10.1.1
AE means any untoward medical occurrence in a patient or subject who has been enrolled in a 
study who has signed informed consent to participate in a study who has signed informed consent 
to participate in a study; the untoward medical occurrence does not necessarily have a causal 
relationship with this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom, or disease temporally associated with the 
use of a medicinal (investigational) product whether or not it is related to the medicinal product. 
This includes any newly occurring event or a previous condition that has increased in severity or 
frequency since the administration of study drug.
An abnormal laboratory value will not be assessed as an AE unless that value leads to 
discontinuation or delay in treatment, dose modification, therapeutic intervention, or is considered 
by the investigator to be a clinically significant change from baseline.
SAE Definition
10.1.2
SAE means any untoward medical occurrence that at any dose:

Results in death.

Is life-threatening (refers to an AE in which the patient was at risk of death at the time of the
event. It does not refer to an event which hypothetically might have caused death if it were
more severe).

Requires inpatient hospitalization or prolongation of an existing hospitalization (see
Section 10.2 on planned hospitalizations).

Results in persistent or significant disability or incapacity. (Disability is defined as a
substantial disruption of a person’s ability to conduct normal life functions).

Is a congenital anomaly/birth defect.

Is a medically important event. This refers to an AE that may not result in death, be
immediately life-threatening, or require hospitalization, but may be considered serious when,
on the basis of appropriate medical judgment, it may jeopardize the patient, require medical or
surgical intervention to prevent one of the outcomes listed above, or involves suspected
transmission via a medicinal product of an infectious agent. Examples of such medical events
include allergic bronchospasm requiring intensive treatment in an emergency room or at home,
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the
development of drug dependency or drug abuse; any organism, virus, or infectious particle
(eg, prion protein transmitting transmissible spongiform encephalopathy), pathogenic or
nonpathogenic, is considered an infectious agent.

Protocol Amendment 03
09 November 2021
In this study, intensity for each AE, including any lab abnormality, will be determined using the 
NCI CTCAE, version 4.03, effective 14 June 2010[6]. Clarification should be made between an 
SAE and an AE that is considered severe in intensity (Grade 3 or 4) because the terms serious and 
severe are NOT synonymous. The general term severe is often used to describe the intensity 
(severity) of a specific event; the event itself, however, may be of relatively minor medical 
significance (such as a Grade 3 headache). This is NOT the same as serious, which is based on 
patient/event outcome or action criteria described above and is usually associated with events that 
pose a threat to a patient’s life or ability to function. A severe AE (Grade 3 or 4) does not 
necessarily need to be considered serious. For example, a white blood cell count of 1000/mm3 to 
less than 2000/mm3 is considered Grade 3 (severe) but may not be considered serious. Seriousness 
(not intensity) serves as a guide for defining regulatory reporting obligations.
10.2
Procedures for Recording and Reporting AEs and SAEs
All AEs spontaneously reported by the patient or in response to an open question from study 
personnel or revealed by observation, physical examination, or other diagnostic procedures will be 
recorded on the appropriate page of the eCRF (see Section 10.3 for the period of observation). Any 
clinically relevant deterioration in laboratory assessments or other clinical finding is considered an 
AE. When possible, signs and symptoms indicating a common underlying pathology should be 
noted as a single comprehensive event.
Regardless of causality, SAEs must be reported by the investigator or subinvestigator to the 
Takeda Global Pharmacovigilance Department or designee (contact information provided below)
(see Section 10.3 for the period of observation). This should be done by faxing, calling or
e-mailing the SAE Form within 24 hours after becoming aware of the event. The SAE Form,
created specifically by Takeda, will be provided to the clinical study site. A sample of the SAE
Form may be found in the Study Manual. SAE report information must be consistent with the data
provided on the eCRF.

Planned hospital admissions or surgical procedures for an illness or disease that existed before the 
patient was enrolled in the trial are not to be considered AEs unless the condition deteriorated in an 
unexpected manner during the trial; eg, surgery was performed earlier or later than planned.
For both serious and nonserious AEs, the investigator or subinvestigator must determine both the 
severity (toxicity grade) of the event and the relationship of the event to study drug administration.
Severity (toxicity grade) for each AE, including any lab abnormality, will be determined using the 
NCI CTCAE, version 4.03, effective 14 June 2010 [6].
Relationship of the event to study drug administration (ie, its causality) will be determined by the 
investigator responding yes (related) or no (unrelated) to this question: Is there a reasonable 
possibility that the AE is associated with the study drug?
10.3
Monitoring of AEs and Period of Observation
AEs, both nonserious and serious, will be monitored throughout the study as follows:

AEs will be reported from the signing of informed consent through 30 days after
administration of the last dose of study drug, whichever comes first, and recorded in the
eCRFs.

SAEs will be reported to the Takeda Global Pharmacovigilance department or designee from
the signing of informed consent through 30 days after administration of the last dose of study
drug, whichever comes first, and recorded in the eCRF. After this period, only related SAEs
must be reported to the Takeda Global Pharmacovigilance department or designee. SAEs
should be monitored until they are resolved or are clearly determined to be due to a patient’s
stable or chronic condition or intercurrent illness(es).
10.4 
Adverse Events of Special Interest
MDS, AML, secondary cancers (new malignancies other than MDS/AML), pneumonitis, and 
embryo-fetal toxicity are Adverse of Special Interest (AESIs) of niraparib. AESIs must be reported 
to the sponsor and recorded as such on the eCRF and on an SAE form; the SAE form must be 
submitted within 24 hours of the investigator becoming aware (Section 10.2). AESI monitoring 
must occur during the study, during follow-up and after study discontinuation.
10.5 
Procedures for Reporting Drug Exposure During Pregnancy and Birth Events
If a woman becomes pregnant or suspects that she is pregnant while participating in this study, she 
must inform the investigator or subinvestigator immediately and permanently discontinue study 
drug. The investigator or subinvestigator must also be contacted immediately by sending a 
completed pregnancy form to the Takeda Global Pharmacovigilance department or designee (see 
Section 10.2). The pregnancy must be followed for the final pregnancy outcome.

Safety Reporting to Investigators, IRBs, and Regulatory Authorities
The sponsor will be responsible for reporting all suspected unexpected serious adverse reactions 
(SUSARs) and any other applicable SAEs to regulatory authorities, investigators, and IRBs and 
the head of the institution, as applicable, in accordance with national regulations in the countries 
where the study is conducted. Relative to the first awareness of the event by/or further provision to 
the sponsor or sponsor’s designee, SUSARs will be submitted to the regulatory authorities as 
expedited reports within 7 days for fatal and life-threatening events and within 15 days for other 
serious events, unless otherwise required by national regulations. The sponsor will also prepare an 
expedited report for other safety issues where these might materially alter the current benefit-risk 
assessment of an investigational medicinal product or that would be sufficient to consider changes 
in the investigational medicinal product’s administration or in the overall conduct of the trial.

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the data management plan. 
AEs, medical history, and concurrent conditions will be coded using the Medical Dictionary for 
Regulatory Activities (MedDRA). Drugs will be coded using the World Health Organization 
(WHO) Drug Dictionary.
12.1 
eCRFs 
Completed eCRFs are required for each subject who has been enrolled in the study.
The sponsor or its designee will supply investigative sites with access to eCRFs and will make 
arrangements to train appropriate site staff in the use of the eCRF. These forms are used to transmit 
the information collected in the performance of this study to the sponsor, CRO partners, and 
regulatory authorities. Investigative sites must complete eCRFs in English.
After completion of the entry process, computer logic checks will be run to identify items such as 
inconsistent dates, missing data, and questionable values. Queries may be issued by Takeda 
personnel (or designee) and will be answered by the site.
Any change of, modification of, or addition to the data on the eCRFs should be made by the 
investigator, subinvestigator or appropriate site personnel. Corrections to eCRFs are recorded in 
an audit trail that captures the old information, the new information, identification of the person 
making the correction, the date the correction was made, and the reason for the change.
The principal investigator must review the eCRFs for completeness and accuracy and must sign 
and date the appropriate eCRFs as indicated. Furthermore, the principal investigator must retain 
full responsibility for the accuracy and authenticity of all data entered on the eCRFs.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by study monitors. The sponsor or designee will be permitted to review the subject’s medical and 
hospital records pertinent to the study to ensure accuracy of the eCRFs. The completed eCRFs are 
the sole property of the sponsor and should not be made available in any form to third parties, 
except for authorized representatives of appropriate governmental health or regulatory authorities, 
without written permission of the sponsor.
12.2 
Record Retention
The investigator and the head of the institution agree to keep the records stipulated in Section 12.1 
and those documents that include (but are not limited to) the study-specific documents, the 
identification log of all participating subjects, medical records, temporary media such as 
thermal-sensitive paper, source worksheets, all original signed and dated ICFs, subject 
authorization forms regarding the use of personal health information (if separate from the ICFs), 
electronic copies of eCRFs including the audit trails, and detailed records of drug disposition to 
enable evaluations or audits from regulatory authorities and the sponsor or designees. Any source 
documentation printed on degradable thermal-sensitive paper should be photocopied by the site 
and filed with the original in the subject’s chart to ensure long-term legibility. Furthermore, ICH

QUALITY CONTROL AND QUALITY ASSURANCE
14.1 
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator guarantee access to source documents by the sponsor or its designee (CRO) and 
by the IRB.
All aspects of the study and its documentation will be subject to review by the sponsor or designee 
(as long as blinding is not jeopardized), including but not limited to the investigator’s binder, study 
medication, subject medical records, informed consent documentation, and review of eCRFs and 
associated source documents. It is important that the investigator, subinvestigator, and other study 
personnel are available during the monitoring visits and that sufficient time is devoted to the 
process.
14.2 
Protocol Deviations
The investigator or subinvestigator can deviate and change from the protocol for any medically 
unavoidable reason, for example, to eliminate an immediate hazard to study subjects, without prior 
written agreement with the sponsor or prior approval from IRB. In the event of a deviation or 
change, the principal investigator should notify the sponsor and the head of the site of the deviation 
or change and its reason in a written form, and then retain a copy of the written form. When 
necessary, the principal investigator may consult and agree with the sponsor on a protocol 
amendment. If the protocol amendment is appropriate, the amendment proposal should be 
submitted to the head of the site as soon as possible, and approval from IRB should be obtained.
The investigator or subinvestigator should document all protocol deviations.
14.3 
Quality Assurance Audits and Regulatory Agency Inspections
The study site also may be subject to quality assurance audits by the sponsor or designees. In this 
circumstance, the sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the medication is stored and prepared, and any other facility used during the study. In 
addition, there is the possibility that this study may be inspected by regulatory agencies, including 
those of foreign governments (eg, the United States [US] Food and Drug Administration [FDA], 
the United Kingdom [UK] Medicines and Healthcare products Regulatory Agency [MHRA], the 
Pharmaceuticals and Medical Devices Agency of Japan [PMDA]). If the study site is contacted for 
an inspection by a regulatory body, the sponsor should be notified immediately. The investigator 
and institution guarantee access for quality assurance auditors to all study documents as described 
in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This study will be conducted with the highest respect for the individual participants (ie, subjects) 
according to the protocol, the ethical principles that have their origin in the Declaration of 
Helsinki, and the ICH Harmonised Tripartite Guideline for GCP. Each investigator will conduct 
the study according to applicable local or regional regulatory requirements and align his or her 
conduct in accordance with the responsibilities of the investigator that are listed in Appendix B. 
The principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
15.1 
IRB Approval
IRBs must be constituted according to the applicable local requirements of each participating 
region. The sponsor or designee will require documentation noting all names and titles of members 
who make up the respective IRB. If any member of the IRB has direct participation in this study, 
written notification regarding his or her abstinence from voting must also be obtained.
The sponsor or designee will supply relevant documents for submission to the respective IRB for 
the protocol’s review and approval. This protocol, the investigator’s brochure, a copy of the ICF, 
and, if applicable, subject recruitment materials and advertisements and other documents required 
by all applicable laws and regulations must be submitted to a central or local IRB for approval. The 
IRB’s written approval of the protocol and subject informed consent must be obtained and 
submitted to the sponsor or designee before commencement of the study, (ie, before shipment of 
the sponsor-supplied drug). The IRB approval must refer to the study by its exact protocol title, 
number, and version date; identify versions of other documents (eg, ICF) reviewed; and state the 
approval date. The sponsor will notify site once the sponsor has confirmed the adequacy of site 
regulatory documentation and, when applicable, the sponsor has received permission from the 
competent authority to begin the trial. Until the site receives notification, no protocol activities, 
including screening, may occur.
Sites must adhere to all requirements stipulated by their respective IRB. This may include 
notification to the IRB regarding protocol amendments, updates to the ICF, recruitment materials 
intended for viewing by subjects, local safety reporting requirements, reports and updates 
regarding the ongoing review of the study at intervals specified by the respective IRB, and 
submission of the investigator’s final status report to IRB. All IRB approvals and relevant 
documentation for these items must be provided to the sponsor (or designee).
Subject incentives should not exert undue influence for participation. Payments to subjects must 
be approved by the IRB and sponsor.
15.2 
Subject Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in the 
Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance with all 
applicable laws and regulations. The ICF describe the planned and permitted uses, transfers, and 
disclosures of the subject’s personal and personal health information for purposes of conducting

the study. The ICF further explain the nature of the study, its objectives, and potential risks and 
benefits, and the date informed consent is given. The ICF will detail the requirements of the 
participant and the fact that he or she is free to withdraw at any time without giving a reason and 
without prejudice to his or her further medical care.
The investigator is responsible for the preparation, content, and IRB approval of the ICF. The ICF 
must be approved by the IRB and the sponsor before use.
The ICF must be written in a language fully comprehensible to the prospective subject. It is the 
responsibility of the investigator or subinvestigator to explain the detailed elements of the ICF to 
the subject. Information should be given in both oral and written form whenever possible and in 
the manner deemed appropriate by the IRB.
The subject must be given ample opportunity to (1) inquire about details of the study and (2) 
decide whether to participate in the study. If the subject determines that he or she will participate in 
the study, then the ICF and subject authorization form (if applicable) must be signed and dated by 
the subject, at the time of consent and before the subject enters into the study. The subject should 
be instructed to sign using their legal names, not nicknames, using a ballpoint pen with either blue 
or black ink. The investigator or subinvestigator must also sign and date the ICF at the time of 
consent and before the subject enters into the study.
Once signed, the original ICF will be stored in the investigator’s site file. The investigator or 
subinvestigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed ICF shall be given to the subject.
All revised ICFs must be reviewed and signed by relevant subjects in the same manner as the 
original informed consent. The date the revised consent was obtained should be recorded in the 
subject’s medical record, and the subject should receive a copy of the revised ICF.
15.3 
Subject Confidentiality
The sponsor and designees affirm and uphold the principle of the subject’s right to protection 
against invasion of privacy. Throughout this study, a subject’s source data will be linked to the 
sponsor’s clinical study database or documentation only via a unique identification number. As 
permitted by all applicable laws and regulations, limited subject attributes, such as sex, age and 
date of birth may be used to verify the subject and accuracy of the subject’s unique identification 
number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit its monitor or designee’s monitor, representatives from any 
regulatory authority (eg, US FDA, UK MHRA, Japan PMDA), the sponsor’s designated auditors, 
and the appropriate IRBs to review the subject’s original medical records (source data or 
documents) including, but not limited to, laboratory test result reports, ECG reports, admission and 
discharge summaries for hospital admissions occurring during a subject’s study participation, and 
autopsy reports. Access to a subject’s original medical records requires the specific authorization 
of the subject as part of the informed consent process (see Section 15.2).

Copies of any subject source documents that are provided to the sponsor must have certain 
identifying personal information removed, (eg, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).
15.4 
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with 
this section and the clinical study site agreement. In the event of any discrepancy between the 
protocol and the clinical study site agreement, the clinical study site agreement will prevail.
15.4.2 Clinical Trial Registration
To ensure that information on clinical trials reaches the public in a timely manner and to comply 
with applicable laws, regulations, and guidance, Takeda will, at a minimum, register interventional 
clinical trials it sponsors anywhere in the world on ClinicalTrials.gov or other publicly accessible 
websites on or before start of study, as defined by Takeda policy/standards. Takeda contact 
information, along with facility name, investigator’s city, state (for Americas investigators), 
country, and recruiting status will be registered and available for public viewing.
As needed, Takeda and investigator/site contact information may be made public to support 
participant access to trials via registries. In certain situations/registries, Takeda may assist 
participants or potential participants in finding a clinical trial by helping them locate trial sites 
closest to their homes by providing the investigator name, address, and phone number via 
email/phone or other methods preferred by callers requesting trial information. Once subjects 
receive investigator contact information, they may call the site requesting enrollment into the trial. 
The investigative sites are encouraged to handle the trial inquiries according to their established 
subject screening process. If the caller asks additional questions beyond the topic of trial 
enrollment, they should be referred to the sponsor.
Any investigator who objects to Takeda providing this information to callers must provide Takeda 
with a written notice requesting that their information not be listed on the registry site.

Takeda will post the results of clinical trials on ClinicalTrials.gov, and other publicly accessible 
websites (including the Takeda corporate site) and registries, as required by Takeda 
policy/standards, applicable laws, and/or regulations.
Data Sharing
The sponsor is committed to responsible sharing of clinical data with the goal of advancing 
medical science and improving patient care. Qualified independent researchers will be permitted 
to use data collected from patients during the study to conduct additional scientific research, which 
may be unrelated to the study drug or the patient’s disease. The data provided to external 
researchers will not include information that identifies patients personally.
15.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the clinical study site agreement regarding the sponsor’s policy on subject compensation 
and treatment for injury. If the investigator has questions regarding this policy, he or she should 
contact the sponsor or sponsor’s designee.

evaluation criteria in solid tumours: Revised RECIST guideline (version 1.1). Eur J Cancer 
2009;45:228-247.
Measurability of Tumor at Baseline
Measureable
Tumor lesions
Must be accurately measured in at least one dimension (longest diameter in the plane of 
measurement is to be recorded) with a minimum size of:

10 mm by CT scan (CT scan slice thickness recommended to be no greater than 5 mm. For a
study site which defines that the slice thickness greater than 5 mm is medically acceptable, the
minimum size for a measurable lesion at baseline should be twice the slice thickness used for
imaging).

10 mm caliper measurement by clinical exam (lesions which cannot be accurately measured
with calipers should be recorded as non-measurable).

20 mm by chest X-ray.
Malignant lymph nodes
To be considered pathologically enlarged and measurable, a lymph node must be ≥15 mm in short 
axis when assessed by CT scan (CT scan slice thickness recommended to be no greater than
5 mm). At baseline and in follow-up, only the short axis will be measured and followed.
Non-measurable
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes 
with ≥10 to <15 mm short axis) as well as truly non-measurable lesions. Lesions considered truly 
non-measurable include: leptomeningeal disease, ascites, pleural or pericardial effusion, 
inflammatory breast disease, lymphangitic involvement of skin or lung, abdominal 
masses/abdominal organomegaly identified by physical exam that is not measurable by 
reproducible imaging techniques.
Tumor Response Evaluation
Target lesions

When more than one measurable lesion is present at baseline, all lesions up to a maximum of
five lesions total (and a maximum of two lesions per organ) representative of all involved
organs should be identified as target lesions and will be recorded and measured at baseline (this
means, for instance, where patients have only one or two organ sites involved a maximum of
two and four lesions, respectively, will be recorded).

Protocol Amendment 03
09 November 2021

Target lesions should be selected on the basis of their size (lesions with the longest diameter),
be representative of all involved organs, but in addition should be those that lend themselves to
reproducible repeated measurements. It may be the case that, on occasion, the largest lesion
does not lend itself to reproducible measurement in which circumstance the next largest lesion
which can be measured reproducibly should be selected

Pathological nodes which are defined as measurable and may be identified as target lesions
must meet the criterion of a short axis of ≥15 mm by CT scan. Only the short axis of these
nodes will contribute to the baseline sum.

A sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all
target lesions will be calculated and reported as the baseline sum diameters.
Non-target lesions
All other lesions (or sites of disease) including pathological lymph nodes should be identified as 
non-target lesions and should also be recorded at baseline. Measurements are not required and 
these lesions should be followed as “present”, “absent”, or in rare cases “unequivocal 
progression”.
Response Criteria
Evaluation of target lesions

CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or
non-target) must have reduction in short axis to <10 mm.

PR: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference
the baseline sum diameters.

PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the
smallest sum on study (this includes the baseline sum if that is the smallest on study). In
addition, the sum must also demonstrate an absolute increase of at least 5 mm.

Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to
qualify for PD, taking as reference the smallest sum diameters while on study.
Evaluation of non-target lesions

CR: Disappearance of all non-target lesions and normalization of tumor marker level. All
lymph nodes must be non-pathological in size (<10 mm short axis).

Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or maintenance of
tumor marker level above the normal limits.

PD: Appearance of unequivocal progression of existing non-target lesions. Unequivocal
progression should not normally trump target lesion status. It must be representative of overall
disease status change, not a single lesion increase.

Protocol Amendment 03
09 November 2021
New lesions

There are no specific criteria for the identification of new radiographic lesions; however, the
finding of a new lesion should be unequivocal.

A lesion identified on a follow-up study in an anatomical location that was not scanned at
baseline is considered a new lesion and will indicate PD.

If a new lesion is equivocal, for example, because of its small size, continued therapy and
follow-up evaluation will clarify if it represents truly new disease. If repeat scans confirm there
is definitely a new lesion, then progression should be declared using the date of the initial scan.
Evaluation of Best Overall Response

The best overall response is the best response recorded from the start of the study treatment
until the end of treatment taking into account any requirement for confirmation.

The patient’s best overall response assignment will depend on the findings of both target and
non-target disease and will also take into consideration the appearance of new lesions.

The best overall response across all time points is determined once all the data for the patient is
known.

In this study, confirmation of complete or partial response is required. Complete or partial
responses may be claimed only if the criteria for each are met 4 weeks or more later (Table 1).
In this circumstance, the best overall response can be interpreted as in Table 3.

When SD is believed to be best response, SD criteria must be met within 4 weeks or more from
baseline (minimum time interval).

(a) If a CR is truly met at first time point, then any disease seen at a subsequent time point, even disease meeting PR
criteria relative to baseline, makes the disease PD at that point (since disease must have reappeared after CR). Best
response would depend on whether minimum duration for SD was met. However, sometimes ‘CR’ may be claimed
when subsequent scans suggest small lesions were likely still present and in fact the patient had PR, not CR at the first
time point. Under these circumstances, the original CR should be changed to PR and the best response is PR.

The duration of overall response is measured from the time measurement criteria are first met
for CR/PR until the first date that recurrent or progressive disease is objectively documented as
assessed per RECIST (v.1.1) or clinical criteria (taking as reference for progressive disease the
smallest measurements recorded on study).

Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used for tumor 
assessment via a computed tomography (CT) or magnetic resonance imaging (MRI) scan of 
abdomen/pelvis and clinically indicated areas, which is required at the end of every 2 cycles (8 
weeks with a window of ±7 days from date of visit) through 6 months (ie, Cycle 6), then at the end 
of every 3 cycles (12 weeks with a window of ±7 days) until progression. Copies of scans will be 
collected for future central evaluation if needed. Cycle timing will not be delayed for treatment 
interruptions, and tumor assessment should occur according to this schedule regardless of whether

used according to RECIST guidelines. Cycle timing will not be delayed for treatment 
interruptions, and tumor assessment should occur according to this schedule regardless of whether 
study treatment is interrupted. If a patient discontinues treatment other than disease progression 
that specified in the protocol, death, consent withdrawn or lost to follow-up, scans and CA-125 
testing should continue at the protocol specified intervals until progression is confirmed or until 
the start of subsequent anticancer therapy as post-treatment. If a patient had a CT/MRI of the 
abdomen/pelvis and clinically indicated areas within the 28-day screening window before Cycle 1 
Day 1 but prior to signing the ICF, the patient is not required to complete an additional CT/MRI 
scan for study screening. CT/MRI scans completed during screening prior to signing the ICF must 
have been performed and be able to be submitted per the image acquisition guidelines. 
Radiographic images will be maintained at each site, and test results and physicians’ findings will 
be filed in subject's source documents. The sponsor may request electronic images for those 
subjects who demonstrate tumor reduction.

OBJECTIVES 
4.1 
Primary Objectives 
To evaluate the efficacy of niraparib in HRD-positive Japanese patients with advanced, relapsed, 
high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have 
received 3 or 4 prior lines of anti-cancer therapy and are platinum-sensitive to the last 
platinum-based therapy. 
4.2 
Secondary Objectives 
To evaluate the safety of niraparib in HRD-positive Japanese patients with advanced, relapsed, 
high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have 
received 3 or 4 prior lines of anti-cancer therapy and are platinum-sensitive to the last 
platinum-based therapy. 
4.3 
Additional Objectives 
To evaluate the pharmacokinetics of niraparib in HRD-positive Japanese patients with advanced, 
relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer, who 
have received 3 or 4 prior lines of anti-cancer therapy and are platinum-sensitive to the last 
platinum-based therapy. 
4.4 
Study Design 
This study is a phase 2, multicenter, open-label, single-arm study to evaluate the safety and 
efficacy of niraparib in patients with advanced, relapsed, high-grade serous epithelial ovarian, 
fallopian tube, or primary peritoneal cancer who have received 3 or 4 previous chemotherapy 
regimens. 
Patients must have received 3 or 4 previous chemotherapy regimens. The study will assess by 
ORR whether treatment with niraparib will benefit HRD positive patients who received 3 or 
4 prior anti-cancer therapies and are platinum-sensitive to the last platinum-based therapy. The 
safety of niraparib will also be assessed in Japanese patients who received 3 or 4 prior anti-
cancer therapies and are platinum-sensitive to the last platinum- based therapy. 
In order to determine eligibility, a tumor sample will be tested for HRD testing. Archival or fresh 
tissue is required in order to enroll in the study. The sample may be tested in advance of the 
protocol-defined screening period (ie, within 40 days before Cycle 1 Day 1) if the consent has 
been obtained, in order to facilitate the screening and enrollment process. Patients must wait for 
the results from the on-study HRD testing provided by the central laboratory prior to enrollment, 
unless they have previously detected gBRCA mutation. If gBRCAmut is detected by a prior 
gBRCAmut testing, then it is not necessary to wait for HRD testing results for enrollment into the 
study, however confirmatory HRD testing still needs to be performed.

Eligible subjects will receive 300 mg/day of the study drug orally QD continuously (in 28-day 
cycles) and the treatment will continue until the patient meet a discontinuation criteria specified 
in the study protocol. 
Dose interruption (no longer than 28 days) and dose reductions (maximum reduction to 
100 mg/day) will be allowed. Dose interruption and/or reduction may be implemented at any 
time for any grade toxicity considered intolerable by the patient. The timing of efficacy or safety 
evaluations should not be affected by dose interruptions or reductions. 
Clinic visits will be weekly during Cycle 1 and then every 4 weeks (±3 days) for subsequent 
cycles. Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used for 
tumor assessment via a computed tomography (CT) or magnetic resonance imaging (MRI) scan 
of abdomen/pelvis and clinically indicated areas, which is required at the end of every 2 cycles 
(8 weeks with a window of ±7 days from date of visit) through 6 months (ie, Cycle 6), then at the 
end of every 3 cycles (12 weeks with a window of ±7 days) until progression. Copies of scans 
will be collected for future central evaluation if needed. Cycle timing will not be delayed for 
treatment interruptions, and tumor assessment should occur according to this schedule regardless 
of whether study treatment is interrupted. 
All AEs will be collected and recorded for each patient from the day of signing the informed 
consent form (ICF) until 30 days after last dose of study treatment administration, or beginning 
of subsequent anticancer therapy, whichever comes first. All AEs and SAEs experienced by a 
patient, irrespective of the suspected causality, will be monitored until the AE or SAE has 
resolved, any abnormal laboratory values have returned to baseline or normalized, until there is a 
satisfactory explanation for the changes observed, until the patient is lost to follow-up, or until 
the patient has died. The Adverse Events of Special Interest (AESIs) for this study are MDS, 
AML, secondary cancers (new primary malignancies other than MDS/AML), pneumonitis, and 
embryo-fetal toxicity. AESIs must be reported to the Sponsor as soon as the investigator 
becomes aware of them. 
Blood samples for measurements of plasma levels of niraparib will be obtained on Cycle 1 Day 1 
predose and 2 hours postdose, Cycle 2 Day 1 predose and 2 hours postdose, and Cycle 4 Day 1 
predose.

METHODS OF ANALYSIS AND PRESENTATION 
7.1 
General Principles  
7.1.1 Study Definitions 
The following definitions and calculation formulas will be used. 
• Treatment-emergent adverse event (TEAE): An adverse event whose date of onset occurs on 
or after the start of study drug and within 30 days after the date of last dose. 
• Pretreatment event (PTE): Any untoward medical occurrence in a clinical investigation 
subject who were enrolled in a study but prior to administration of study drug. 
• Descriptive statistics: Number of subjects, mean, standard deviation, maximum, minimum, 
and quartiles. 
• Dose Level: 300 mg, 200 mg, 100 mg. 
• Total Study Duration (days): Last visit date or date of death - Enrollment date + 1. 
• Overall Treatment Exposure (days): Date of last dose - date of first dose + 1 
• Dose intensity (mg/day): Sum of the total daily doses ingested divided by Overall Treatment 
Exposure. 
• Relative Dose Intensity (%): Dose intensity (mg/day) divided by intended dose intensity 
(mg/day) multiplied by 100, where intended dose intensity is 300 (mg/day). 
• Dose reduction regardless of causality: Dose consumed is less than prescribed for any reason. 
• Dose interruptions regardless of causality: Dose consumed is 0 mg for any reason (includes 
missed doses). 
• Dose interruptions due to AE: Dose consumed is 0 mg due to AE. 
• Initial dose level for each cycle: Dose level on the first date when dose is not 0 mg for each 
cycle. 
• DCR: The proportion of patients achieving best overall response of CR, PR, or stable disease 
(SD) as assessed by the Investigator per RECIST (v1.1).  
• DOR: The time from the earliest date of initial response date of confirmed CR or PR until the 
earlier date of radiological progressive disease (PD) or death by any cause. The DOR (months) 
will be calculated as: (Earliest date of radiological PD or Death – Earliest of (Date of 
confirmed CR or PR) + 1) / 30.4375.  
General censoring rules for the analysis of DOR will be as follows: 
– Patients known to be alive and known not to have started new (non-protocol) anti-cancer 
treatment, who are progression-free, and who have a baseline and at least 1 post-dosing

CONFIDENTIAL 
radiological assessment, are censored at the date of the last radiological assessment that 
verified lack of PD. 
– Patients starting new anti-cancer treatment prior to or on progression or death are 
censored at the date of last radiological assessment documenting no progression prior to 
the new anti-cancer treatment. 
• PFS: The time from the date of first dose of study treatment to the earlier date of assessment 
of radiological progression or death by any cause. Progression-free survival (months) will be 
calculated as: (Earlier of (Date of radiological PD or Death) - First dose date + 1) / 30.4375.  
General censoring rules for the analysis of PFS will be as follows: 
– No adequate post-baseline radiological assessments and no death; therefore PFS is 
censored at the date of the first dose unless death occurred. 
– Patients known to be alive and known not to have started new (non-protocol) anti-cancer 
treatment, who are progression-free, and who have a baseline and at least 1 post-dosing 
radiological assessment, are censored at the date of the last radiological assessment that 
verified lack of PD. 
– Patients starting new anti-cancer treatment prior to progression or death are censored at 
the date of last radiological assessment documenting no progression prior to the new anti-
cancer treatment. 
• OS: The time from the date of first dose of study treatment to the date of death by any cause. 
Patients known to be alive will be censored at the last known survival follow-up date. The 
OS (months) will be calculated as: (Death date - First dose date + 1) / 30.4375. 
• TFST: The date of first dose of study treatment in the current study to the earlier date of first 
dose of first new anti-cancer treatment or death. Patients who are alive without a new anti-
cancer treatment will be censored on the last contact date. TFST (months) will be calculated 
as: (Earlier of (First dose of first new anti-cancer treatment or death – First dose date + 1) / 
30.4375. 
• For waterfall plot of best percent change in target lesion size (section 7.9.3.1) and subgroup 
analysis (section 7.9.4.7), tumor BRCA1/BRCA2 mutation status will be dichotomized as 
“Positive” or “Negative” (“Negative” or “Unknown”); “Unknown” is combined with 
“Negative”. 
• TEAE leading to study drug modification: Any TEAE leading to dose reduction, dose 
interruption or dose discontinuation. 
7.1.2 Definition of Study Days 
The following definitions and calculation formulas will be used. 
• Study Day: The day before the first dose of the study drug will be defined as Study Day -1 
and the day of the first dose will be defined as Study Day 1. If the date of the observation is

CONFIDENTIAL 
on the same date or after the day of the first dose, Study Day will be calculated relative to 
Study Day 1. Otherwise, Study Day will be calculated relative to Study Day -1. 
• Follow-up Day: The day after the last dose of the study drug will be defined as Follow-up 
Day 1. Follow-up Day will be calculated relative to Day 1. 
7.1.3 Definition of Study Visit Windows 
When calculating Study Day relative to a reference date (ie, date of first dose [Day 1]), if the 
date of the observation is on the same date or after the reference date, it will be calculated as: 
date of observation - reference date + 1; otherwise, it will be calculated as: date of observation - 
reference date. Hence, reference day is always Day 1 and there is no Day 0.  
When calculating Follow-up Day relative to a reference date (ie, date of last dose [Follow-up 
Day 0]), it will be calculated as: date of observation - reference date. Hence, reference day is 
always Follow-up Day 0. 
All evaluable data (ie, non-missing data) will be handled according to the following rules. 
For each visit, observation obtained in the corresponding time interval will be used. If more than 
one observation lies within the same visit window, the observation with the closest Study Day to 
the scheduled Study Day will be used. If there are two observations equidistant to the scheduled 
Study Day, the earlier observation will be used. 
If multiple observations exist on the same date, the observation whose Hemoglobin value is 
lower (the value before transfusion) will be used for analysis.

7.1.4 Significance Level and Confidence Coefficient 
• Significance level: 5% (one-sided test). 
• Confidence coefficient: 
– Analysis for ORR: 90% (two-sided). 
– Analysis for other endpoints: ORR 95% (two-sided). 
7.1.5 Conventions for Missing Dates 
When calculating the “Duration between the End Date of the Last Chemotherapy Regimen and 
the First Dose of Study Treatment (months)”, missing the day or day and month of the end date 
of last chemotherapy will be set as follows. If the day is missing, the day will be assumed to be 
the first date of the month when the last chemotherapy was used. If the imputed date of the end 
of the last chemotherapy is earlier than the end date of the previous chemotherapy, the imputed 
date is set to the next day of the end date of the previous chemotherapy. If the day and month are 
both missing, the day and month will be assumed to be January 1. If the imputed date of the end 
of the last chemotherapy is earlier than the end date of the previous chemotherapy, the imputed 
date is set to the next day of the end date of the previous chemotherapy. 
When calculating the “Time from First Diagnosis to First Dose (years)”, missing the day or day 
and month of the date of the first diagnosis will be set as follows. If the day is missing, the day 
will be assumed to be the first date of the month when the subject was first diagnosed. If the day 
and month are both missing, the day and month will be assumed to be January 1.
