Brief summary:
This is an open-label, single-arm pilot study evaluating the antitumor activity and safety of niraparib as neoadjuvant therapy in participants with Human epidermal growth factor receptor 2 (HER2)-negative and breast cancer susceptibility gene mutant (BRCAmut) localized breast cancer (primary tumor \>=1 centimeters \[cm\]). Breast magnetic resonance imaging (MRI), breast ultrasound, and tumor core biopsy will be performed at the screening (Days -28 to -1). Participants will receive niraparib (200 milligrams \[mg\] orally \[PO\]) treatment daily for 28 days (Cycle 1) and then will undergo breast ultrasound at the end of Cycle 1 on Day 28. Based on breast ultrasound reports, the participants will either discontinue the study (disease progression) or will continue niraparib treatment (complete response \[CR\], partial response \[PR\] or stable disease \[SD\]) for an additional cycle (Cycle 2). A breast MRI and breast ultrasound will be performed at the end of Cycle 2. Approximately 21 participants will be enrolled in this study and the study duration will be approximately 2 years.

Detailed description:

Arms:
arm 1: Participants with HER2-negative and BRCAmut localized breast cancer (primary tumor \>=1 cm) will receive niraparib (200 mg PO).

Interventions: intervention 1: Niraparib
Intervention descriptions: intervention 1: Niraparib is a potent, orally active, highly selective poly adenosine diphosphate (\[ADP\]-ribose) polymerase 1 (PARP1) and PARP2 inhibitor.

Name of Active Ingredient: Niraparib 
Title of Study: An Open-Label, Single-arm Pilot Study Evaluating the Antitumor Activity and 
Safety of Niraparib as Neoadjuvant Treatment in Localized, HER2-negative, BRCA-mutant 
Breast Cancer Patients  
Study center(s): North America (multicenter) 
Studied period (years):  
Estimated date first patient enrolled: April 2018 
Estimated date last patient completed: TBD 
Phase of development:  
Pilot Study 
Objectives:  
Primary: 
• 
To evaluate the preliminary antitumor activity of niraparib assessed as the tumor response 
rate based on the change in tumor volume as measured by breast MRI, observed after 
treatment with niraparib in the neoadjuvant treatment of localized, human epidermal 
growth factor receptor 2 (HER2)-negative, breast cancer susceptibility gene (BRCA) 
mutant (BRCAmut) breast cancer patients.  
Secondary: 
• 
To evaluate the preliminary antitumor activity of niraparib assessed by: 
− 
Presence of pathological complete response (pCR) defined as ypT0/Tis ypN0 by 
receipt of pre-operative chemotherapy (Yes versus No) 
− 
Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment by MRI and ultrasound 
− 
Tumor response rate based on the change in tumor volume as measured by breast 
ultrasound 
• 
To evaluate safety and tolerability of niraparib per the current version of the National 
Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03 
criteria  
Exploratory: 
• 
To evaluate niraparib-induced changes in immune responses 
• 
To explore intra-tumoral niraparib concentration and correlation with blood  
• 
To estimate the preliminary antitumor activity of niraparib in BRCAmut triple-negative breast 
cancer (TNBC) patients and BRCAmut hormone-positive patients 
• 
To evaluate pharmacodynamic inhibition of PARP activity in the tumor

• 
To explore molecular biomarkers related to disease biology or response to treatment 
using tumor tissue or liquid biopsy approaches (e.g. ctDNA) 
Methodology:  
This is an open-label, single-arm pilot study evaluating the antitumor activity and safety of niraparib 
as neoadjuvant therapy in patients with HER2-negative and BRCAmut localized breast cancer 
(primary tumor ≥1 cm). The study design is summarized in the schema below. If antitumor activity in 
the BRCAmut cohort is demonstrated, the protocol may be amended to add a homologous 
recombination deficiency (HRD)-positive, BRCA-wild type cohort. 
Study Schema 
 
 
1Patients may receive up to 6 months of niraparib (see Section 7). 
2Breast ultrasounds are performed at the end of each month for those patients receiving additional 
cycles. 
3Core biopsy will be obtained preferably within 24 hours of the last dose of niraparib in cycle 2 and 
prior to any subsequent anticancer therapy or procedure. A surgical biopsy may be used in lieu of a 
core biopsy provided that surgery occurs within 24 hours of the last dose of niraparib in Cycle 2. 
4Tumor size cut-off for pre-surgery chemotherapy will be determined by investigator discretion.  
5Off-study visit is for the collection of pCR results for patients for whom the Safety Follow-up/EOT 
Visit occurred prior to surgery; for all other patients the Safety Follow-up/EOT Visit will act as the 
off-study visit. 
Breast magnetic resonance imaging (MRI), breast ultrasound, and tumor core biopsy will be 
performed at the Screening (-28 to -1 Day 1). 
Patients will receive niraparib (200 mg orally [PO]) treatment daily for 28 days (Cycle 1) and then 
will undergo breast ultrasound at the end of Cycle 1 on Day 28: 
• 
If breast ultrasound shows disease progression defined as an increase in tumor volume by 
greater than 20% by Investigator assessment, the patient will discontinue the study. If 
breast ultrasound shows complete response, partial response, or stable disease by 
Investigator assessment, the patient will continue niraparib treatment 200 mg PO for an 
additional cycle (Cycle 2). Patients may receive up to 6 months of niraparib treatment if, 
in the opinion of the Investigator and Sponsor, and agreed upon by the Sponsor, the 
patient would benefit from additional treatment.

A breast MRI and breast ultrasound will be performed at the end of Cycle 2. The investigational team 
will determine if the patient will proceed to surgery or to neoadjuvant chemotherapy.  
A core biopsy will be performed at the end of Cycle 2, which should occur within 24 hours of the last 
dose of niraparib. Niraparib treatment may be extended up to an additional 7 days after Cycle 2 Day 
28 to allow for scheduling of surgery or the core biopsy: 
• 
For those patients proceeding directly to surgery at the end of Cycle 2, a surgical biopsy may 
be obtained at the time of surgery provided that surgery occurs within 24 hours of the last 
dose of niraparib on Cycle 2 Day 28 (+7 days).  
• 
For all other patients, provided that their tumors are amenable to biopsy, a core biopsy should 
be obtained within 24 hours of the last dose of niraparib on Cycle 2 Day 28 (+7 days). The 
biopsy should be performed after the MRI and ultrasound and prior to any subsequent 
anticancer therapy.  
At the completion of all neoadjuvant therapy, patients will proceed to surgery and/or other local 
treatment as deemed appropriate by the investigator. For those patients who receive neoadjuvant 
therapy (niraparib alone or niraparib followed by chemotherapy), a pCR assessment will be made at 
the time of surgery. 
Patients shall discontinue treatment in case of unacceptable toxicity or withdrawal of consent. 
All adverse events (AEs) will be collected and recorded for each patient from the day of signing the 
informed consent form until 30 days after last study drug administration. 
Selected non-serious AEs and serious adverse events (SAEs) are also known as adverse events of 
special interest (AESI) and must be recorded as such on the electronic case report form (eCRF) and 
reported within 24 hours to the Sponsor as soon as the Investigator becomes aware of them. 
SAEs are required to be captured through 90 days after the last dose of study drug (or to a minimum 
of 30 days post treatment if the patient starts alternate anticancer therapy). All SAEs assessed by the 
Investigator as related to the study drug and AESIs will be collected and reported until study closeout. 
Any pregnancies that occur up to and including 180 days post-treatment will be reported. Pregnancies 
occurring more than 180 days after last dose, with an associated SAE (considered causally related to 
the study drug by the Investigator) will follow the SAE reporting requirements. 
All AEs and SAEs experienced by a patient, irrespective of the suspected causality, will be monitored 
until the AE or SAE has resolved, until 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. 
Number of patients (planned): Approximately 20 
Diagnosis and main criteria for inclusion:

Duration of treatment:  
Approximately 56 days. 
Reference therapy, dosage and mode of administration:  
Not applicable 
Criteria for evaluation: 
Efficacy: 
The primary efficacy endpoint is: 
• 
Tumor response rate based on the change in tumor volume as measured by breast MRI; a 
response is considered ≥30% reduction of tumor volume from baseline after 2 months of 
niraparib treatment. Tumor volume will be calculated as (length × width × height × π)/6. 
The secondary efficacy endpoints are: 
• 
pCR rate: pCR is defined as ypT0/Tis ypN0 by receipt of pre-operative chemotherapy (Yes vs. 
No). Pathological complete response (pCR) is defined as the absence of residual invasive 
cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all 
sampled regional lymph nodes following completion of neoadjuvant systemic therapy (i.e., 
ypT0/Tis ypN0 in the current AJCC staging system1). 
• 
Tumor response rate based on the change in tumor volume as measured by breast ultrasound; 
a response is considered ≥30% reduction of tumor volume from baseline after 2 months of 
niraparib treatment. Tumor volume will be calculated as (length × width × height × π)/6. 
• 
Percentage change in tumor volume from baseline after 2 months of niraparib treatment as 
measured by ultrasound. Tumor volume will be calculated as (length × width × height × π)/6. 
• 
Percentage change in tumor volume from baseline after 2 months of niraparib treatment as 
measured by MRI. Tumor volume will be calculated as (length × width × height × π)/6. 
The exploratory endpoints are: 
• 
Immune-related changes in gene expression profiles and cellular composition (eg, T-cells, 
myeloid cells, and natural killer cells) in pre vs. post niraparib treatment tumor samples 
• 
Niraparib concentration in post treatment tumor samples and correlation with PK in 
peripheral blood 
• 
Estimation of change in tumor volume in BRCAmut TNBC patients and in BRCAmut 
hormone-positive patients 
• 
Comparison of PARP enzymatic activity (eg, PARylation), DNA damage and repair (eg, 
phosphorylated histone H2AX, RAD51), proliferation (eg, Ki67) and survival (eg, Caspase 3) 
in pre vs. post niraparib treatment tumor samples 
• 
Potential biomarkers of sensitivity or resistance (e.g. BRCA reversion mutations, loss of 
heterozygosity [LOH]) in ctDNA or tumor tissue 
• 
Targeted (or whole exome) sequencing for other disease related molecular alterations with 
remaining blood or tumor samples

Statistical methods: 
No formal sample size calculation is done for this study. The sample size is determined based on the 
clinical considerations only.  
A total of approximately 20 evaluable patients will be enrolled. This sample size should be sufficient 
for signal finding prior to initiating a larger study. For example, it will provide approximately 80% 
power with 1-sided significance level of 0.15 to differentiate a response rate of 80% from a minimum 
response rate of 60%. Other examples are provided below.

The safety population includes all patients who received any dose of study medication. The safety 
population will be the primary analysis population for the safety analyses. 
The efficacy evaluable population includes all patients who completed 2 cycles of treatment. The 
efficacy evaluable population will be the primary analysis population for the efficacy analyses. 
No formal statistical testing will be done for this study. Data will be summarized in a descriptive 
nature. Categorical variables will be summarized by frequency distributions (number and percentage 
of patients). Continuous variables will be summarized by the mean, standard deviation, median, 
minimum, maximum, first quartile and third quartile.  
Tumor response rate will be tabulated together with its 95% binomial exact confidence interval (CI). 
The change in tumor volume from baseline will be summarized using descriptive statistics. Data from 
patients who received neoadjuvant niraparib only will be analyzed separately from those who 
received neoadjuvant niraparib followed by neoadjuvant chemotherapy. 
Summary statistics will be provided for safety endpoints including TEAEs, clinical laboratory 
evaluations (hematology, chemistry, and urinalysis), vital signs, electrocardiograms, physical 
examinations, and use of concomitant medications.

INTRODUCTION 
5.1. 
Background 
5.1.1. 
Breast Cancer 
Breast cancer is the most common cancer in women worldwide, with nearly 1.7 million new 
cases diagnosed in 2012 (second most common cancer overall). This represents about 12% of all 
new cancer cases and 25% of all cancers in women.2 In the United States of America (U.S.), 
approximately 1 in 8 women (about 12%) will develop invasive breast cancer over the course of 
her lifetime. In the U.S. alone, it is estimated that there will be 252,710 new cases of female 
breast cancer and an estimated 40,610 people will die of this disease in 2017.3 In Europe, more 
than 464,000 new cases of breast cancer were estimated to have been diagnosed in 2012.4 
Approximately 20 to 25 % of hereditary breast cancers and 5 to 10% of all breast cancers are 
associated with pathogenic germline alterations in breast cancer susceptibility gene (BRCA)1 and 
BRCA2.5,6 Women with BRCA mutations have a lifetime risk of developing breast cancer of 45 
to 75%.7-9 BRCAmut breast cancer is characterized by more aggressive phenotype than sporadic 
breast cancer, with BRCA1-mutated breast cancer being more frequently high grade and triple 
negative, and BRCA2-mutated breast cancer being on average of higher histological grade than 
sporadic cases.7,10,11 BRCA1 mutation carriers have worse overall survival (OS) than 
BRCA-wildtype cases (hazard ratio [HR]: 1.30, 95% CI: 1.11–1.52) and worse breast 
cancer-specific survival (BCSS) than sporadic/BRCA-wildtype cases among patients with stage 
I–III breast cancer (HR 1.45, 95% CI: 1.01–2.07). BRCA2 mutation carriers have worse BCSS 
than sporadic/BRCA-wildtype cases (HR 1.29, 95% CI: 1.03–1.62), although they have similar 
OS. Among Ashkenazi Jewish women, BRCA1/2 mutation carriers presented higher risk of death 
from breast cancer (HR 1.44, 95% CI: 1.05–1.97) and of distant metastases (HR 1.82, 95% CI: 
1.05–3.16) than sporadic/BRCA-wildtype patients.12 
BRCA1/2-mutant cells are hypersensitive to inactivation of poly (ADP-ribose) polymerase 1 
(PARP-1), garnering great interest in the treatment of breast cancer patients with 
BRCA1/2-mutant disease via PARP inhibition. The PARP inhibitor olaparib was assessed for 
efficacy and safety in women with BRCA1 or BRCA2-mutant advanced breast cancer.13 In this 
proof-of concept phase 2 study, women were assigned to two sequential cohorts, the first cohort 
(n = 27) was given continuous oral olaparib at the maximum tolerated dose (400 mg twice daily), 
and the second (n = 27) was given a lower dose (100 mg twice daily). The primary objective was 
objective response rate (ORR); ORR was 11 (41%) of 27 patients (95% CI 25–59) in the cohort 
assigned to 400 mg twice daily, and 6 (22%) of 273,12,14,15 in the cohort assigned to 100 mg twice 
daily. The results of this study provided proof of concept for PARP inhibition in BRCAmut 
breast cancers and shows a favorable therapeutic index for a novel targeted treatment strategy in 
patients with tumors that have genetic loss of function of BRCA1-associated or 
BRCA2-associated deoxyribonucleic acid (DNA) repair. 
More recently, the ABRAZO study was initiated to investigate the use of PARP inhibitor 
talazoparib in patients with gBRCA1/2 mutation previously exposed to platinum or multiple prior 
cytotoxic regimens (Turner et al 2017).16 This study is a 2-cohort, 2-stage phase 2 study of 
talazoparib following platinum-based therapy (Cohort 1 [C1]) or ≥ 3 platinum-free 
cytotoxic-based regimens (Cohort 2 [C2]) in patients with locally advanced or metastatic breast

cancer and gBRCA1/2 mutation. Five responses per cohort were required in ≤ 35 patients to 
progress to stage 2. The primary endpoint was confirmed ORR by independent radiology facility. 
As of Sep 2016, 84 patients had enrolled (C1, n = 49; C2, n = 35). Both cohorts proceeded to 
stage 2 before enrollment closed. Triple negative breast cancer (TNBC)/human epidermal growth 
factor receptor 2 (HER2)-positive (TNBC/HER2-positive) breast cancer incidence in C1 and C2 
was 59%/41% and 17%/83%, respectively. ORR for BRCA1/BRCA2 was 24%/34%, and ORR by 
for TNBC/HER2-positive was 26%/29%. Based on these data, the phase 3 EMBRACA trial was 
initiated to test the use of talazoparib versus physician’s choice of treatment in 
gBRCA1/2-mutated metastatic breast cancer. 
The efficacy and tolerability of the PARP inhibitor veliparib was tested in combination with 
carboplatin and paclitaxel versus placebo given with carboplatin and paclitaxel in patients with 
BRCA1 or BRCA2 mutations and metastatic breast cancer in the BROCADE study.17 In this 
randomized, phase 2 study, 290 patients with BRCA1 or BRCA2 mutation were randomized to 
three arms: 97 were randomized to veliparib plus carboplatin and paclitaxel, 99 to placebo plus 
carboplatin and paclitaxel, and 94 to veliparib plus temozolomide. The overall response rate for 
the veliparib arm was 77.8%, compared with 61.3% for the placebo arm. The improvement in 
progression-free survival in the veliparib arm (14.1 vs 12.3 months) was not statistically 
significant. The trend to improved overall survival was also not statistically significant (28.3 vs 
25.9 months). These results indicate that not all PARP inhibitors can be expected to be effective 
in the treatment of BRCA1/2-mutant breast cancer, thus requiring careful investigation for the 
optimal treatment of these patients in each setting. 
Most recently and importantly, the benefit of treatment with olaparib was confirmed in the 
phase 3 OlympiAD study, which included 302 patients with HER2-negative metastatic breast 
cancer who harbored germline BRCA1 or BRCA2 mutations. Patients were randomized to 
olaparib (300 mg twice daily) or physician’s choice of standard chemotherapy (capecitabine, 
vinorelbine, or eribulin). The primary endpoint of the trial was progression free survival (PFS) 
per a blinded independent review. Results showed a statistically-significant and 
clinically-meaningful improvement in PFS for patients treated with olaparib tablets compared to 
treatment with physician’s choice of a standard of care chemotherapy. In addition to meeting its 
primary endpoint, the trial showed that patients treated with olaparib had a 42% reduction in risk 
of their disease worsening or death (HR 0.58; 95% CI 0.43-0.80; p=0.0009; median 7.0 vs 
4.2 months) compared to those who received chemotherapy (capecitabine, vinorelbine, 
eribulin).18 Secondary endpoints showed an improvement in time until second progression or 
death (PFS2) in the olaparib arm of the trial versus those treated with chemotherapy (HR 0.57; 
95% CI: 0.40-0.83). In addition, the ORR was more than doubled, with 59.9% of patients in the 
olaparib arm showing response to treatment, compared to 28.8% of patients treated with 
chemotherapy. Notably, there was a lower incidence of grade ≥3 adverse events (AEs) in the 
olaparib arm compared to the chemotherapy arm (36.6% vs 50.5% respectively). This study 
establishes PARP inhibition with olaparib as effective in the treatment of BRCA1/2-mutant breast 
cancer. 
Originally developed for patients with locally advanced breast cancer, neoadjuvant 
chemotherapy is now frequently administered to patients with operable breast cancers. The 
outcomes of neoadjuvant chemotherapy were demonstrated in a 2007 meta-analysis that included 
data from 5500 women participating in 1 of 14 trials reported between 1991 and 2001.3 


Niraparib

Compared with adjuvant chemotherapy, neoadjuvant chemotherapy resulted in a reduction in the 
risk of having a modified radical mastectomy performed (hazard ratio [HR] 0.71, 95% CI 
0.67-0.75), but equivalent OS (HR 0.98, 95% CI 0.87-1.09) and disease free survival (DFS) (HR 
0.97, 95% CI 0.89-1.07). Among patients treated with neoadjuvant chemotherapy, a documented 
pathologic complete response (pCR) at surgery was prognostically significant in that these 
patients had significant improvements in both OS (HR 0.48, 95% CI 0.33-0.69) and DFS (HR 
0.48, 95% CI 0.37-0.63) compared with patients with residual invasive disease.14,15,19 These 
differences are more pronounced in patients with more proliferative breast cancer subtypes, 
including triple-negative breast cancer (TNBC; event-free survival [EFS] HR 0.24 for pCR 
versus not) and HER2-positive breast cancer (EFS HR 0.39 for pCR versus not).15 Commonly 
used regimens for patients with HER2-negative disease include anthracycline-based regimens 
such as doxorubicin and cyclophosphamide followed or preceded by a taxane (docetaxel or 
paclitaxel) and nonanthracycline-containing regimens such as docetaxel and cyclophosphamide, 
amongst others.  
In an effort to improve outcomes, additions to these agents, including antiangiogenesis agents 
have been investigated. The GeparQuinto phase 3 study was initiated in part to investigate 
subtype-specific treatment approaches for patients with HER2-negative primary breast cancer 
(group 1).20 In this group, the rates of pCR after neoadjuvant chemotherapy with or without 
bevacizumab was evaluated. Results from this prespecified subgroup analyses suggested that the 
effect of bevacizumab derived mainly from patients with triple-negative breast cancer (odds 
ratio, 1.67). However, the test for interaction was not significant (P = 0.07) in this study, which 
was not powered to show these differential effects. In the National Surgical Adjuvant Breast and 
Bowel Project B-40 study a numerical but statistically nonsignificant increase in the rate of pCR 
was reported with the use of bevacizumab in the subgroup of 490 patients with triple-negative 
breast cancer.21 In both studies, higher rates of bleeding, thromboembolic events, and 
postsurgical complications (early and late) were seen with the addition of bevacizumab therapy. 
The use of PARP inhibitors has also been investigated in combination with chemotherapy in the 
neoadjuvant setting. Most recently, a pilot study of talazoparib for early-stage breast cancer 
patients with a BRCA mutation was initiated22. Thirteen patients were enrolled in initial stage of 
the study, BRCA1-mutant=10; BRCA2-mutant=3. Eight had hormone receptor negative and 4 had 
hormone receptor positive breast cancer, and 1 metaplastic. Two had clinical stage III, 9 had 
clinical stage II, and 2 had clinical stage I cancers. Decreases in tumor volume occurred in all 
13 patients following 2 months of talazoparib monotherapy, with an average volume loss of 78% 
(range 30-98%). Talazoparib was well tolerated with no grade 4 toxicities and only one patient 
requiring dose reduction due to grade 3 neutropenia. Given the profound clinical response with 
only 2 months of therapy and favorable toxicity profile, the pilot study was discontinued early 
and an expansion cohort to estimate pathologic response to talazoparib alone with 4 to 6 months 
is underway. This small study provides early evidence of proof-of-concept in the treatment of 
BRCA1/2-mutant breast cancer with PARP inhibition. 
5.1.1.1. 
Niraparib: Pre-Clinical Summary 
Niraparib is a potent and selective PARP-1 and PARP-2 inhibitor with half maximal inhibitory 
concentration of control (IC50) of 3.8 and 2.1 nM, respectively, and is at least 100-fold selective 
over other PARP-family members. Niraparib inhibits PARP activity stimulated as a result of

Page 23 of 77 
 
 
DNA damage caused by addition of hydrogen peroxide in various cell lines with an IC50 and a 
90% inhibitory concentration of control (IC90) of about 4 and 50 nM, respectively.23 
Niraparib demonstrates selective anti-proliferative activity for cancer cell lines that have been 
silenced for BRCA1 or BRCA2 or carry BRCA1 or BRCA2 mutations as compared to their wild 
type counterparts. Niraparib demonstrates weak activity on normal human cells. 
Niraparib displayed strong antitumor activity in in vivo studies with BRCA1 mutant breast cancer 
(MDA-MB-436), BRCA2 mutant pancreatic cancer, ataxia telangiectasia-mutant mantle cell 
lymphoma (GRANTA- 519), serous ovarian cancer (OVCAR3), and colorectal cancer (HT29 
and DLD-1) xenograft models and with patient-derived Ewing’s sarcoma mice models. 
Moreover, Murai et al demonstrated in 2012 that niraparib is the most potent amongst a series of 
5 PARP inhibitors in trapping PARP.24  
Nonclinical testing of niraparib did not indicate any untoward effects that would prevent clinical 
investigation in the human setting. Nonclinical pharmacology studies with niraparib have 
generated sufficient data to support its clinical evaluation as a monotherapy for patients with 
advanced/metastatic breast cancer with BRCA mutation. 
Details of the nonclinical studies conducted with niraparib can be found in the current 
Investigator’s Brochure. 
5.1.1.2. 
Niraparib: Clinical Summary 
Clinical studies have shown that PARP inhibitors are active in recurrent ovarian cancer.25-31  
PARP inhibition appears to be most active in patients with germline breast cancer susceptibility 
gene (gBRCA) mutation and in patients who are sensitive to platinum-containing therapy. 
However, clinical benefit has also been observed in gBRCA wild-type.27-30 Maintenance 
treatment of high-grade serous ovarian cancer patients with recurrent platinum sensitivity 
showed that the PARP1/2 inhibitor niraparib significantly improved PFS in gBRCAmut patients 
(21 months for niraparib vs. 5.5 months for control). Furthermore, in the gBRCA wild-type 
population, significant improvement in PFS also was observed (9.3 months for niraparib versus 
3.9 months for placebo, HR = 0.45, p<0.0001).31,32 Zejula™ (niraparib) has been recently 
approved for the maintenance treatment of adult patients with recurrent epithelial ovarian, 
fallopian tube, or primary peritoneal cancer. For more details, refer to Zejula label.33 
There are 3 ongoing Phase 3 niraparib studies, Study PR-30-5010-C (BRAVO), Study 
PR-30-5017-C (PRIMA), and Study PR-30-5011-C (NOVA). There is also 1 ongoing Phase 1/2 
study, Study 3000-PN162-01-001 (TOPACIO) and 1 ongoing Phase 2 study, Study 
PR-30-5020-C (QUADRA). 
NOVA is a double-blind, placebo-controlled study in patients with platinum-sensitive ovarian 
cancer who have received at least 2 platinum-based regimens.32  A total of 553 patients were 
categorized according to the presence or absence of a gBRCAmut (gBRCA cohort and 
non-gBRCA cohort) and the type of non-gBRCAmut, and were randomly assigned in a 2:1 ratio 
to receive niraparib (300 mg) or placebo once daily (QD). The primary endpoint was PFS. The 
study enrolled 203 patients in the gBRCAmut cohort and 350 patients in the non-gBRCAmut 
cohort. Among the 350 patients in the non-gBRCAmut cohort, 162 had tumors that were defined 
as HRD positive and 134 had tumors that were HRD negative. HRD status was not determined 
for 54 patients.

Demographic and baseline characteristics were well balanced. Table 3 shows the results for the 
PFS primary endpoint for each of the 3 primary efficacy populations (ie, gBRCA-mutant cohort, 
HRD positive cohort, and overall non-gBRCAmut cohort). In addition, median PFS in patients 
with HRD negative tumors was 6.9 months (95% CI: 5.6, 9.6) in the niraparib arm vs. 
3.8 months (95% CI: 3.7, 5.6) in the placebo arm, with an HR of 0.58 (95% CI: 0.361, 0.922) 
(p=0.0226).

The primary data to support the safety of treatment with niraparib are derived from the NOVA 
main study in which a total of 546 patients received study drug. All 367 patients who received 
niraparib and 171 (96%) of 179 patients who received placebo experienced at least 
1 treatment-emergent adverse event (TEAE). The high rate of TEAEs in the placebo group 
indicates the burden of prior chemotherapy and the patient’s underlying ovarian cancer. Review 
of the data across study cohorts for TEAE incidence showed that, in general, the results were 
similar in the gBRCAmut and non-gBRCAmut cohorts. In the overall safety population, for the 
niraparib vs. placebo treatment arms, the incidences of Grade 3 to 4 TEAEs (74% vs. 23%), 
serious adverse events (SAEs) (30% vs. 15%), TEAEs leading to treatment interruption (69% vs. 
5%), TEAEs leading to dose reduction (67% vs. 15%), and TEAEs leading to treatment 
discontinuation (15% vs 2%) were higher for niraparib. There were no on-treatment deaths 
reported. 
The most commonly observed nonhematologic TEAEs (all grades) observed in niraparib 
compared to placebo-treated patients were nausea (74% vs. 35%), fatigue (46% vs. 32%), 
constipation (40% vs. 20%), and vomiting (34% vs. 16%). The majority of the nonhematological 
TEAEs were mild to moderate in severity. The most commonly observed hematologic TEAEs 
(all grades) of niraparib were anemia (49%), thrombocytopenia (46%), and neutropenia (18%). 
Although Grade 3 to 4 hematologic laboratory events were common at the initiation of treatment, 
no severe clinical sequelae were observed, and relatively few patients discontinued due to these 
AEs. Dose adjustment based on individual tolerability during the first 3 cycles substantially 


Niraparib

Page 25 of 77 
 
 
reduced the incidence of these events beyond Cycle 3, indicating the overall effectiveness of the 
approach to dose modification. These TEAEs can be monitored routinely using standard 
assessments of hematological laboratory parameters, as is routine for patients with ovarian 
cancer receiving anticancer therapies. In the NOVA study, niraparib dose adjustment tended to 
occur early with most patients reaching their individual adjusted dose level at the end of Month 3 
(ie, Cycle 3) of treatment. Approximately 36% patients were kept on 300 mg and approximately 
64% patients had dose adjustments after 3 cycles in NOVA. However, in the Phase 1 portion of 
the TOPACIO study (combination of niraparib and pembrolizumab), no patients were able to 
tolerate the 300 mg dose of niraparib. 
Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) are potential adverse 
class effects associated with PARP inhibitors.34 MDS and AML therefore represent a potential 
risk to patients receiving niraparib. In the Phase 3 NOVA study, the incidence of MDS/AML in 
patients who received niraparib (5 of 367; 1.4%) was similar to its incidence in patients who 
received placebo (2 of 179; 1.1%). Guidance on monitoring patients for new events of 
MDS/AML and the follow-up of patients with suspected MDS/AML is provided in 
Section 13.1.8.  
Study PR-30-5011-C1 (NOVA corrected QT interval [QTc] substudy n = 26) was an open-label 
evaluation of the effects of niraparib on QTc measurements in patients with histologically 
diagnosed ovarian cancer, fallopian tube cancer, or primary peritoneal cancer. There were no 
reports of clinically significant abnormal electrocardiogram (ECG) changes, including QTc 
interval prolongation, attributed to niraparib. Administration of niraparib at the therapeutic dose 
did not prolong the QT interval. There was no correlation between the exposure level (ie, plasma 
concentration) of niraparib and QTc changes (ie, changes in QTc using Fridericia’s formula). 
MDS and AML have been observed in patients receiving treatment with olaparib, a PARP 
inhibitor; given the common mechanism of action, MDS and AML therefore represent a 
potential risk to patients receiving niraparib.  
Details of the clinical studies conducted with niraparib can be found in the current Investigator's 
Brochure. 
5.1.1.3. 
Study Rationale 
This study aims to investigate the preliminary antitumor activity of niraparib assessed as the 
change in tumor volume observed after treatment with niraparib in the neoadjuvant treatment of 
localized, HER2-negative, BRCAmut breast cancer patients.

TRIAL OBJECTIVES AND PURPOSE 
6.1. 
Primary Objective 
• To evaluate the preliminary antitumor activity of niraparib assessed as the tumor response 
rate based on the change in tumor volume as measured by breast MRI, observed after 
treatment with niraparib in the neoadjuvant treatment of localized, human epidermal 
growth factor receptor 2 (HER2) negative, breast cancer susceptibility gene (BRCA) 
mutant breast cancer patients. 
6.2. 
Secondary Objectives 
• To evaluate the preliminary antitumor activity of niraparib assessed by:  
− Presence of pCR defined as ypT0/Tis ypN0 by receipt of pre-operative 
chemotherapy (Yes versus No) 
− Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment 
− Tumor response rate based on the change in tumor volume as measured by breast 
ultrasound 
• To evaluate safety and tolerability of niraparib per National Cancer Institute-Common 
Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03 criteria 
6.3. 
Exploratory Objectives 
• To evaluate niraparib-induced changes in immune responses 
• To explore intra-tumoral niraparib concentration and correlation with blood  
• To estimate the preliminary antitumor activity of niraparib in BRCAmut TNBC 
patients and BRCAmut hormone-positive patients 
• To evaluate pharmacodynamic inhibition of PARP activity in the tumor 
• To explore molecular biomarkers related to disease biology or response to treatment 
using tumor tissue or liquid biopsy approaches (e.g. ctDNA)

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This is an open-label, single-arm pilot study evaluating the antitumor activity and safety of 
niraparib as neoadjuvant therapy in patients with HER2-negative and BRCAmut localized breast 
cancer (primary tumor ≥1 cm). The study design is summarized in Figure 1. If antitumor activity 
in the BRCAmut cohort is demonstrated, the protocol may be amended to add an HRD-positive, 
BRCA-wild type cohort. 
Figure 1: 
Study Schema 
 
 
1Patients may receive up to 6 months of niraparib (see Section 7). 
2Breast ultrasounds are performed at the end of each month for those patients receiving additional cycles. 
3Core biopsy will be obtained preferably within 24 hours of the last dose of niraparib in cycle 2 and prior to any subsequent 
anticancer therapy or procedure. A surgical biopsy may be used in lieu of a core biopsy provided that surgery occurs within 24 
hours of the last dose of niraparib in Cycle 2. 
4Tumor size cut-off for pre-surgery chemotherapy will be determined by investigator discretion.  
5Off-study visit is for the collection of pCR results for patients for whom the Safety Follow-up/EOT Visit occurred prior to 
surgery; for all other patients the Safety Follow-up/EOT Visit will act as the off-study visit. 
Breast magnetic resonance imaging (MRI), breast ultrasound, and tumor core biopsy will be 
performed at the Screening (Day -28 to Day -1). 
Patients will receive niraparib (200 mg orally [PO]) treatment daily for 28 days (Cycle 1) and 
then will undergo breast ultrasound at the end of Cycle 1 on Day 28: 
• If breast ultrasound shows disease progression defined as an increase in tumor 
volume by greater than 20% by Investigator assessment, the patient will discontinue 
study. If breast ultrasound shows CR, PR or stable disease (SD) by Investigator 
assessment (please see Appendix 2), the patient will continue niraparib treatment 
200 mg PO for an additional cycle (Cycle 2). Patients may receive up to 6 months of 
niraparib treatment if, in the opinion of the Investigator and Sponsor, and agreed upon 
by the Sponsor, the patient would benefit from additional treatment. 
A breast MRI and breast ultrasound will be performed at the end of Cycle 2. The investigational 
team will determine if the patient will proceed to surgery or to standard of care neoadjuvant 
chemotherapy.  


Niraparib

A core biopsy will be performed at the end of Cycle 2, which should occur within 24 hours of the 
last dose of niraparib. Niraparib treatment may be extended up to an additional 7 days after 
Cycle 2 Day 28 to allow for scheduling of surgery or the core biopsy: 
• For those patients proceeding directly to surgery at the end of Cycle 2, a surgical biopsy 
may be obtained at the time of surgery provided that surgery occurs within 24 hours of 
the last dose of niraparib on Cycle 2 Day 28 (+7 days).  
• For all other patients, provided that their tumors are amenable to biopsy, a core biopsy 
should be obtained within 24 hours of the last dose of niraparib on Cycle 2 Day 28 
(+7 days). The biopsy should be performed after the MRI and ultrasound and prior to any 
subsequent anticancer therapy.  
At the completion of all neoadjuvant therapy, patients will proceed to surgery and/or other local 
treatment as deemed appropriate by the investigator. For those patients who receive neoadjuvant 
therapy (niraparib alone or niraparib followed by chemotherapy), a pCR assessment will be made 
at the time of surgery. 
Patients shall discontinue treatment in case of unacceptable toxicity or withdrawal of consent. 
AEs, regardless of the source of identification (eg, physical examination, laboratory assessment, 
ECG, or reported by patient), will be collected and recorded in the electronic case report form 
(eCRF) for each patient from the day of signed informed consent form until 30 days after last 
dose of study treatment. 
SAEs and adverse events of special interest (AESIs) concerning hypertension and hematologic 
toxicities will be collected and recorded in the eCRF and on an SAE report form for each patient 
from the date of signed informed consent until 90 days after the last dose of study drug (or until 
the start of alternate anticancer therapy, whichever occurs first). 
Related SAEs (assessed as related to study drug by the Investigator) will be collected for each 
patient from the date of signed informed consent until study closeout. 
AESIs concerning MDS/AML, secondary cancers, pneumonitis, and embryo-fetal toxicity must 
be collected and reported to the Sponsor for each patient from the date of signed informed 
consent until study closeout. 
Any pregnancies that occur up to and including 180 days post treatment will be reported. 
Pregnancies occurring more than 180 days after last dose, with an associated SAE (considered 
causally related to the study drug by the Investigator) will follow the SAE reporting 
requirements. 
7.1.1. 
General Study Conduct 
This study will consist of a Screening Period (Day -28 to Day -1), a Treatment Period, 
Presurgery chemotherapy (if appropriate), Surgery, a Safety Follow-up/EOT visit occurring 
30 days (+7 days) after the last dose of study medication, and an Off-Study Visit for the purposes 
of collecting the pCR results for patients for whom the Safety Follow-up/EOT Visit occurred 
prior to surgery; for all other patients the Safety Follow-up/EOT Visit will act as the off-study 
visit.

Following informed consent, all patients will undergo screening procedures within 28 days prior 
to the first dose of study drug to determine eligibility for study entry. Screening procedures 
include medical, surgical, cancer, and medication history; complete physical examination, 
including vital signs, height, and weight; Eastern Cooperative Oncology Group (ECOG) 
performance status; clinical laboratory assessments (complete blood count [CBC], serum 
chemistry, and urinalysis); pregnancy test for women of childbearing potential; and ECG. 
Patients must have a baseline tumor assessment by ultrasound and MRI to determine extent of 
disease and confirm presence of measurable disease. Tumor volume will be calculated at 
baseline and after Cycle 2 via MRI and ultrasound as follows: (length × width × height × π)/6.35 
Patients will also undergo core biopsy at baseline and at the end of Cycle 2 obtained preferably 
within 24 hours of the last dose of niraparib, after the MRI and ultrasound, and prior to any 
subsequent anticancer therapy. A surgical biopsy may be used in lieu of a core biopsy provided 
that surgery occurs within 24 hours of the last dose of niraparib in Cycle 2. Niraparib treatment 
may be extended up to an additional 7 days after Cycle 2 Day 28 to allow for scheduling of 
surgery or the core biopsy. During treatment, patients will undergo a breast ultrasound at the end 
of each 28-day cycle. If the breast ultrasound shows disease progression defined as an increase in 
tumor volume by greater than 20% by Investigator assessment, the patient will discontinue the 
study. If the breast ultrasound shows CR, PR, or SD by Investigator assessment (please see 
Appendix 2) at the end of Cycle 1, the patient will continue niraparib treatment 200 mg PO for 
an additional cycle (Cycle 2). Patients may receive up to 6 months of niraparib treatment if, in 
the opinion of the Investigator and Sponsor, and agreed upon by the Sponsor, the patient would 
benefit from additional treatment. 
At the completion of neoadjuvant treatment with niraparib, patients will be assessed for 
presurgery neoadjuvant chemotherapy, the appropriateness of which is up to the Investigator’s 
clinical judgment. For those patients who receive neoadjuvant therapy (niraparib alone or 
niraparib followed by chemotherapy), a pCR assessment will be made at the time of surgery. 
Pathological complete response (pCR) is defined as the absence of residual invasive cancer on 
hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional 
lymph nodes following completion of neoadjuvant systemic therapy (i.e., ypT0/Tis ypN0 in the 
current AJCC staging system). 
Safety assessments conducted throughout the study include symptom-directed physical 
examination, vital signs, ECOG performance status, clinical laboratory assessments (CBC, serum 
chemistry, and urinalysis) (Table 6). 
Blood samples will be collected predose on Day 1 of Cycles 1 and 2, and at 2 and 4 hours post 
dose, and in conjunction with the post-treatment core biopsy to evaluate PK of niraparib. 
Blood samples for the analysis of circulating tumor DNA (ctDNA) will be collected at 
Screening, on Cycle 1/Day 28 predose, on Cycle 2/Day 28 predose, and at presurgery 
assessment. BRCA, HER2,estrogen receptor (ER), progesterone (PR) status must be available for 
all patients. All patients will undergo a Safety Follow-up/EOT Visit occurring 30 days (+7 days) 
post treatment.

7.2. 
Number of Patients 
A total of approximately 20 evaluable patients will be enrolled. This sample size should be 
sufficient for signal finding prior to initiating a larger study. For example, it will provide 
approximately 80% power with 1-sided significance level of 0.15 to differentiate a response rate 
of 80% from a minimum response rate of 60%. 
7.3. 
Treatment Assignment 
All patients in this single-arm study will receive neoadjuvant treatment with niraparib for 
2 cycles and up to 6 cycles if, in the opinion of the Investigator and Sponsor, and agreed upon by 
the Sponsor, the patient would benefit from additional treatment. 
7.4. 
Dose Adjustment Criteria 
Dose interruption and/or reduction may be implemented at any time for any grade toxicity 
considered intolerable by the patient. In addition, protocol-defined criteria for dose modification 
are discussed below. 
Treatment must be interrupted for any treatment- related non-hematologic Common 
Terminology Criteria for Adverse Events v 4.03 (CTCAE), Grade 3 or 4 AE or SAE that the 
Investigator considers to be related to the administration of niraparib. If the toxicity is resolved to 
baseline or  Grade ≤1 within 28 days, the patient may restart treatment with niraparib but with a 
dose level reduction unless prophylaxis is considered feasible (Table 4). If the event recurs at a 
similar or worse grade, treatment should be interrupted again, and upon resolution, a further dose 
reduction must be made. If upon rechallenging with niraparib at the lowest allowable dose, any 
CTCAE Grade 3 or 4 AEs recur, the patient must be discontinued. At the Investigator’s 
discretion, following dose interruption (no longer than 28 days), patients may be considered for a 
dose reduction (no more than 1 dose reduction will be permitted). For major surgery, up to 
28 days of drug interruption is allowed. 
In the case of dose interruptions, the next cycle will follow the patient's original calendar 
schedule. Cycle timing will not be delayed for treatment interruptions, and tumor assessment 
should occur according to this schedule regardless of whether study drug is interrupted. 
Additional laboratory work-up prior to next treatment initiation should also be performed at the 
physician's discretion. Missed doses of niraparib (ie, any dose that is not administered within the 
protocol-defined administration window) will not be taken at a later date. 
If the toxicity requiring dose interruption has not resolved completely or has not been reduced to 
NCI-CTCAE v.4.03 criteria Grade ≤1 during a maximum of 4 weeks (28 days) of dose 
interruption period, and/or the patient has already undergone a maximum of one dose reduction 
(to a minimum dose of 100 mg QD), the patient must permanently discontinue treatment with 
niraparib.

Management of hematologic toxicities is described in Table 5. For Grade 3 or 4 neutropenia, 
thrombocytopenia, or anemia, treatment with niraparib must be interrupted with weekly blood 
counts monitored until recovery (neutrophils ≥1,500/μL, platelets ≥100,000/μL, or hemoglobin 
≥9.0 g/dL, respectively). Niraparib should be resumed with a dose level reduction at that time. 
Cytokines (granulocyte colony stimulating factor) may be administered as clinically indicated 
according to local standard of care.  
For major surgery not related to the breast tumor, up to 28 days of drug interruption is allowed. 
Thrombocytopenia is an expected event associated with the use of niraparib and is described in 
the Investigator’s Brochure. Thrombocytopenia associated with the use of niraparib resolved 
upon treatment interruption and/or dose reduction. The occurrence of thrombocytopenia during 
Cycle 1 requires additional patient monitoring in order to identify hematologic changes early and 
prevent higher grade thrombocytopenic events. A weekly monitoring of CBC during the first 
month is considered mandatory. 
If a patient completes the first cycle with no incidence of hematologic toxicity requiring dose 
interruption or modification, then CBC monitoring will proceed according to protocol every 
3 weeks, thereafter. If dose interruption or modification is required at any point on study, weekly 
CBC will be required for another 4 weeks after the AE has been resolved, to ensure safety of the 
new dose, after which monitoring every 3 weeks may resume. 
Any patient requiring transfusion of platelets or red blood cells (on two different occasions) or 
hematopoietic growth factor support must undergo a niraparib dose reduction upon recovery if 
study drug is resumed. 
It is strongly recommended to refer the patient to the hematologist for further evaluation if (1) 
transfusions are required on more than 2 occasions in the absence of non-treatment related causes 
or (2) the treatment-related hematologic toxicities have not recovered to allow retreatment with 
niraparib after 4 weeks. If a diagnosis of MDS/AML is confirmed by a hematologist, the patient 
must permanently discontinue study drug.

8.4. 
Patient Withdrawal Criteria 
8.4.1. 
Discontinuation from Treatment 
Patients may be discontinued from study drug at any time. Specific reasons for discontinuing all 
study drugs include the following: 
• Unacceptable toxicity that cannot be managed by dose modification 
• Disease progression as outlined per Response Evaluation Criteria in Solid Tumors 
v1.136 
• In the best interest of the patient as judged by the Investigator and/or Sponsor 
• Severe noncompliance with the protocol as judged by the Investigator and/or Sponsor 
• Withdrawal of consent  
− Note: All reasonable efforts should be made to encourage patients to remain on 
study even if they withdraw from treatment.  
• Patient becomes pregnant 
• Sponsor decision to terminate study 
• Death 
Details of required niraparib dose modifications, including interruptions, dose reductions, and 
permanent discontinuations, related to toxicity, are provided in Section 7.4 . 
Patients who discontinue from study drug will continue to receive follow-up assessments 
(Table 6) as part of the study unless they are discontinued from the study. 
8.4.2. 
Discontinuation from the Study 
Patients may be discontinued from the study for any of the following reasons: 
• Withdrawal of consent by the patient, who is at any time free to discontinue their 
participation in the study 
• Death from any cause 
• Lost to follow-up 
• Sponsor decision to terminate study 
Patients who withdraw from study drug will be asked to continue the study visits and 
assessments as outlined in the Schedule of Events (Section 7.1.1, Table 6). If a patient is lost to 
follow-up, attempts should be made to contact the patient to determine the reason for 
discontinuation. For patients who are lost to follow-up, at least three documented attempts, 
including one via certified mail, should be made to contact the patient before considering the 
patient lost to follow-up. 
If a patient discontinues study drug prior to the second MRI assessment of disease (scheduled 
radiological assessment at the end of Cycle 2), the patient may be replaced for the purposes of

Concomitant Medications 
Any medication the patient takes during the study other than the study drugs, including herbal 
and other nontraditional remedies, is considered a concomitant medication. All concomitant 
medications must be recorded in the eCRF. The following information must be recorded in the 
eCRF for each concomitant medication: generic name, route of administration, start date, stop 
date, dosage, and indication. Any changes in the dosage or regimen of a concomitant medication 
must be recorded in the eCRF. 
At screening, patients will be asked what medications they have taken during the last 30 days. At 
each subsequent study visit, patients will be asked what concomitant medications they are 
currently taking or have taken since the previous visit. 
Niraparib weakly induces cytochrome P450 (CYP)1A2 in vitro and is an insensitive substrate for 
P-glycoprotein (P-gp); therefore, investigators should be advised to use caution with drugs that 
are the sensitive substrates for CYP1A2 with a narrow therapeutic range, i.e. theophylline and 
tizanidine. 
9.2.1. 
Prohibited Medications 
Patients are prohibited from receiving the following therapies during the screening and treatment 
phase of this study: 
• Antineoplastic systemic chemotherapy or biological therapy 
• Radiation therapy or immunotherapy  
• Chemotherapy during niraparib treatment 
• Investigational agents other than niraparib  
• Live vaccines within 30 days prior to the first dose of study drug and while 
participating in the study. Examples of live vaccines include, but are not limited to, 
the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, Bacille 


Niraparib

Calmette-Guerin, and typhoid (PO) vaccine. Seasonal influenza vaccines for injection 
are generally killed virus vaccines and are allowed. However, intranasal influenza 
vaccines (eg, Flu-Mist®) are live attenuated vaccines and, therefore, are not allowed. 
• Prophylactic cytokines (granulocyte colony-stimulating factor) should not be 
administered in the first cycle of the study but may be administered in subsequent 
cycles according to current American Society of Clinical Oncology guidelines.37 
If there is a clinical indication for any medication or vaccination specifically prohibited during 
the study, discontinuation from study drug may be required. The Investigator should discuss any 
questions regarding this with the Sponsor. The final decision on any supportive therapy or 
vaccination rests with the Investigator and/or the patient’s primary physician. The decision to 
continue the patient on study drug, however, requires the mutual agreement of the Investigator, 
the Sponsor, and the patient. 
9.2.2. 
Contraception 
Niraparib is known to have properties that require the patient to use contraception. For details on 
niraparib, please refer to the Investigator’s Brochure. 
The following are considered adequate barrier methods of contraception: diaphragm, condom (by 
the partner), copper intrauterine device, sponge, or spermicide per local regulations or guidelines. 
Appropriate hormonal contraceptives will include any registered and marketed contraceptive 
agent that contains an estrogen and/or a progestational agent (including PO, subcutaneous, 
intrauterine, or intramuscular agents). Abstinence is acceptable if this is the established and 
preferred contraception for the patient. 
Patients should be informed that taking the study medication may involve unknown risks to the 
fetus if pregnancy were to occur during the study. In order to participate in the study female 
patients must adhere to the contraception requirement (described above) for the duration of the 
study and through 180 days after the last study drug. Male patients should not donate sperm or 
father children from screening throughout the duration of the study up to 120 days after the last 
dose of study drug is received. If there is any question that a patient will not reliably comply with 
the requirements for contraception, that patient should not be entered into the study. 
9.2.3. 
Other Study Restrictions 
Patients who are blood donors should not donate blood during the study and for 90 days after the 
last dose of study drug. 
Patients should maintain a normal diet unless modifications are required to manage an AE such 
as diarrhea, nausea, or vomiting. 
9.3. 
Treatment Compliance 
Compliance with inclusion and exclusion criteria will be assessed as outlined in Section 8 and 
Section 8.2, respectively. 
Niraparib will be administered by site personnel at study sites as detailed in Section 10.5. 
Study drug accountability will be monitored as detailed in Section 10.7.

10.6. 
Presurgery Chemotherapy 
The decision to proceed to surgery or to pursue neoadjuvant chemotherapy following treatment 
with niraparib will be at the discretion of the treating investigator. Details regarding neoadjuvant 
chemotherapy, including agents, start and stop dates, will be recorded in the eCRF. 
10.7. 
Study Drug Accountability 
The Investigator or designee is responsible for maintaining accurate dispensing records of the 
study treatments throughout the clinical study. Study drug accountability should be maintained 
by each site based on the capsules dispensed versus returned to the clinic at each visit and the 
number of days since the last visit. 
Details of maintaining drug accountability, including information on the accountability log, will 
be provided in the Pharmacy Manual. 
All dispensation and accountability records will be available for the Sponsor review. The Study 
Monitor will assume the responsibility to reconcile the study treatment accountability log. The 
pharmacist will dispense study treatment for each patient according to the protocol and the 
Pharmacy Manual, if applicable.

ASSESSMENT OF EFFICACY 
11.1. 
Efficacy Endpoints 
11.1.1. 
Primary Endpoint 
• Tumor response rate based on the change in tumor volume as measured by breast 
MRI.; a response is considered at least >30% reduction of tumor volume from 
baseline after 2 months of niraparib treatment. Tumor volume will be calculated as 
(length × width × height × π)/6.35 
11.1.2. 
Secondary Endpoints 
• pCR: pCR is defined as ypT0/Tis ypN0 by receipt of pre-operative chemotherapy 
(Yes vs. No). pCR is defined as the absence of residual invasive cancer on 
hematoxylin and eosin evaluation of the complete resected breast specimen and all 
sampled regional lymph nodes following completion of neoadjuvant systemic therapy 
(i.e., ypT0/Tis ypN0 in the current AJCC staging system1). 
• Tumor response rate based on the change in tumor volume as measured by breast 
ultrasound; a response is considered ≥30% reduction of tumor volume from baseline 
after 2 months of niraparib treatment. Tumor volume will be calculated as 
(length × width × height × π)/6.35 
• Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment as measured by ultrasound. Tumor volume will be calculated as 
(length × width × height × π)/6.35 
• Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment as measured by MRI. Tumor volume will be calculated as 
(length × width × height × π)/6.35 
11.2. 
Exploratory Endpoints 
• Immune-related changes in gene expression profiles and cellular composition (eg, 
T-cells, myeloid cells, and natural killer cells) in pre vs. post niraparib treatment tumor 
samples 
• Niraparib concentration in post treatment tumor samples and correlation with PK in 
peripheral blood 
• Estimation of change in tumor volume in BRCAmut TNBC patients and in BRCAmut 
hormone-positive patients 
• Comparison of PARP enzymatic activity (eg, PARylation), DNA damage and repair (eg, 
phosphorylated histone H2AX, RAD51), proliferation (eg, Ki67) and survival (eg, 
Caspase 3) in pre vs. post niraparib treatment tumor samples 
• Potential biomarkers of sensitivity or resistance (e.g. BRCA reversion mutations, LOH) in 
ctDNA or tumor tissue

TRANSLATIONAL RESEARCH 
The overall aims of translational research are the following: to evaluate the effect of niraparib 
treatment on the tumor immune contexture, as well as PD changes in the tumor; to explore molecular 
mechanisms mediating resistance to niraparib; and to assess the potential of blood-based predictive 
biomarkers, such as circulating tumor DNA. 
12.1. 
Effect of Niraparib Treatment on the Tumor Immune Contexture 
and Pharmacodynamic Changes in Tumor Cells 
12.1.1. 
Tumor Immune Contexture 
The immunologic underpinnings of a tumor play an important role in disease progression and 
response to anticancer therapies. However, the effect of PARP inhibitor treatment on the cancer 
immune response has not been well characterized. There is an emerging evidence suggesting that 
niraparib treatment may affect the tumor immune contexture, turning a cold (non-inflamed) 
tumor into a hot (inflamed) one. The effect may manifest as changes in immune-related gene 
expression profiles, cellular composition of tumor infiltrating immune cells (eg, T cells, myeloid 
cells, NK cells), as well as signaling pathways (eg, STING/IFN a/b), and chemokine/cytokine 
profiles. Better understanding of the immune modulatory effect of niraparib will help the 
development of more effective combination therapies. Tumor biopsies, collected in formalin-
fixed paraffin embedded (FFPE) before and after niraparib treatment, will be analyzed for 
biomarkers related to breast cancer biology, PARP inhibition, or immune oncology (eg, gene 
expression profiling), as well as immune phenotyping using multiplex immunofluorescence 
techniques. 
12.1.2. 
Intra-tumoral Niraparib Concentration 
Efficient tumor penetration is essential for achieving complete inhibition of PARP activity in all 
malignant cells within a tumor nodule. Preclinical data showed that niraparib has excellent tumor 
penetrance property. To evaluate concentration of niraparib in tumors, a post-treatment biopsy, 
collected within 24 hours after last dose of niraparib is needed. Niraparib concentration in tumor 
will be correlated with blood PK parameters, PD endpoints, and efficacy outcomes. 
12.1.3. 
Pharmacodynamic Changes 
Niraparib is a potent and selective inhibitor of PARP1 and PARP2. In tumors with deficiency in 
homologous recombination, the inhibition of PARP activity will lead to accumulation of 
unrepaired DNA damage and cell death. Fresh frozen tumor biopsies, collected before and after 
niraparib treatment, will be analyzed for PARP enzymatic activity (eg, PARylation assay). In 
addition, the FFPE biopsies will be analyzed for DNA damage and repair (eg, γH2AX, RAD51), 
proliferation (eg, Ki67), and cell death (eg, Cleaved Caspase 3)-related biomarkers. 
The studies detailed above will be conducted on frozen and FFPE core biopsies collected during 
the Screening and again at the end of Cycle 2. The biopsy at the end of Cycle 2 should be taken 
within 24 hours of the last dose of niraparib, whenever possible, to preserve the effects induced 
by niraparib treatment. A surgical biopsy may be used in lieu of a core biopsy provided that 
surgery occurs within 24 hours of the last dose of niraparib in Cycle 2.

12.1.4. 
Molecular Mechanisms Mediating Resistance to Niraparib in BRCAmut 
Population 
BRCAmut leads to malignancies deficient in homologous recombination and responsiveness to 
PARP inhibitors. However, many changes within the tumor (eg, BRCA reversion mutation, loss 
of 53BP1 expression) can partially restore homologous recombination function and cause 
resistance to PARP inhibitors. In addition, it has been shown that, in ovarian cancer patients with 
germline BRCA mutations, loss of heterozygosity (LOH) in the tumor is correlated with stronger 
clinical benefit from platinum based therapies. To study these sensitivity/resistance mechanisms, 
tumor sample from surgery may be deep sequenced to look for coexistent genomic alternations. 
If enough RNA can be extracted, gene expression of these tumors may be evaluated by 
sequencing technology or alternative methods.

Assessment of Blood-based Predictive Biomarkers for Niraparib 
Efficacy and Resistance 
12.2.1. 
BRCA Status and Other Biomarker Analysis of Circulating Tumor DNA 
Plasma of most cancer patients contains ctDNA that carries information on tumor mutations and 
tumor burden. This information can be reliably retrieved with deep sequencing technology and 
may be useful as a minimally-invasive way of monitoring cancer genomic alterations (mutations, 
rearrangements). A next-generation sequencing (NGS)-based ctDNA panel, which includes both 
BRCA1 and BRCA2, has been developed and validated for investigational use only. This test can 
be used to identify patients with BRCA1/2 mutations for enrollment into this study. In addition, 
ctDNA analyses may allow tracking and monitoring of tumor dynamics during treatment, as well 
as the emergence of resistant subclones. ctDNA analysis will be conducted to evaluate genomic 
alternations, such as BRCA reversion mutations, LOH, and their correlation with response to 
treatment.

Adverse Events and Special Situations 
13.2.1. 
Definition  
13.2.1.1. Adverse Event (AE) 
Any untoward medical occurrence in a patient or clinical investigation subject administered a 
medicinal product and which does not necessarily have to have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including a clinically 
significant abnormal laboratory finding, for example), symptom, or disease temporally 
associated with the use of study treatment, whether or not considered related to the study 
treatment.  
AEs may include the onset of new illness and the exacerbation of pre-existing medical 
conditions. An AE can include an undesirable medical condition occurring at any time after the 
time of randomization and/or treatment assignment, including baseline or washout periods, even 
if no study treatment has been administered.  (See Section 13.2.3 for information about AE 
collecting and reporting.)

Page 56 of 77 
 
 
13.2.1.2. Serious Adverse Event (SAE) 
Any untoward medical occurrence that, at any dose; 
• Results in death;  
• Is life threatening (i.e., an event in which the patient was at risk of death at the time of 
the event; it does not refer to an event that hypothetically might have caused death if 
it were more severe);  
• Requires inpatient hospitalization* or prolongation of existing hospitalization;  
• Results in persistent or significant disability/incapacity;  
• Is a congenital anomaly/birth defect; or 
• Is an important medical event** 
*Exception: Preplanned (at time of informed consent) hospitalization for elective procedures, for 
protocol compliance or social reasons, or for observation will not be considered criteria for an 
SAE. The reason for the planned hospitalization should be captured in medical history section in 
the eCRF. Complications experienced during these hospitalizations must be reported as AEs (or 
SAEs, if hospitalization is prolonged due to the AE).  
**Medical and scientific judgment should be exercised in determining whether situations or 
events should be considered serious adverse events:  an important medical event may not be 
immediately life-threatening or result in death or require hospitalization but may jeopardize the 
patient or require intervention to prevent one of the above outcomes.  Examples of such events 
are allergic bronchospasm, blood dyscrasias, or convulsions that may require intensive treatment 
in an emergency room or at home but do not result in hospitalization, development of drug 
dependency or drug abuse, and transmission of disease associated with the administration of the 
study drug. (See Section 13.2.5 for information about SAE reporting.) 
13.2.1.3. Treatment-Emergent Adverse Event (TEAE) 
Any event that was not present prior to the initiation of study treatment or any event already 
present that worsens in either intensity or frequency following exposure to study treatment. 
13.2.1.4. Adverse Event of Special Interest (AESI) 
Any AE (serious or non-serious) that is of scientific and medical concern specific to the study 
treatment, for which ongoing monitoring and rapid communication by the Investigator to the 
Sponsor is appropriate. 
13.2.1.5. Special Situations: Abuse, Misuse, Medication Errors, Overdose, and Accidental 
or Occupational Exposure 
• Abuse:  is the persistent or sporadic, intentional excessive use of the study treatment 
which is accompanied by harmful physical or psychological effects.  
• Misuse: medicinal product is intentionally and inappropriately used not in accordance 
with the authorized/approved product information. 


Niraparib 
 
 
Clinical Study Protocol 3000-01-005 Version 2.0

Page 57 of 77 
 
 
• Medication error:  is any preventable incident that may cause or lead to 
inappropriate study treatment use or patient harm while the study treatment is in the 
control of the health care professionals or patients. Such incident may be due to 
health care professional practice, product labeling, packaging and preparation, 
procedures for administration, and systems, including the following: prescribing, 
order communication, nomenclature, compounding, dispensing, distribution, 
administration, education, monitoring, and use. 
• Overdose:  is a deliberate or accidental administration of study treatment to a study 
patient, at a dose greater than that which was assigned to that patient per the study 
protocol and under the direction of the Investigator.  If an overdose occurs, the 
Investigator and the Sponsor should be notified immediately, and the patient should 
be observed closely for AEs. Associated AEs should be treated and monitored by the 
Investigator. The dosage of study drug administered, any associated AEs, and/or 
treatment provided to the patient because of the overdose, should be documented on 
the applicable sections within the eCRF. An overdose (including an AE or SAE 
resulting from the overdose, if any) will be reported as described in Section 13.2.5. 
• Accidental /Occupational exposure:  is the unintentional exposure to a study 
treatment as a result of one’s professional or non-professional occupation, or 
accidental exposure to a non-professional to whom exposure was not intended (i.e., 
study product given to wrong patient).  
Reporting Special Situations:  All occurrences of abuse, misuse, medication error, overdose, and 
accidental or occupational exposure with any study treatment must be reported on an SAE 
Report Form [or designated Special Form] to the Sponsor regardless of whether or not an AE or 
SAE has occurred. If the abuse, misuse, medication error, overdose, or accidental / occupational 
exposure is associated with an SAE, an SAE report form must be submitted to the Sponsor 
within 24 hours of awareness. If there is no AE or SAE, the occurrence must be submitted on the 
designated Special Form (indicate ‘no AE has occurred’) as soon as possible. 
13.2.2. 
Assessment of Adverse Events 
13.2.2.1. Severity Assessment 
All AEs will be assessed by the Investigator for severity* according to Common Terminology 
Criteria for Adverse Events (CTCAE) v4.03: 14 June 2010; National Institutes of Health (NIH), 
National Cancer Institute (NCI). The CTCAE severity grades 1 through 5 provide unique clinical 
descriptions of severity of each adverse event. The CTCAE v4.03 is available on the NCI/NIH 
website. 
Please note that there is a distinction between serious and severe AEs: Severity is a measure of 
intensity whereas seriousness is defined by the criteria in Section 13.2.1.2.  For example, a mild 
degree of gastrointestinal bleeding requiring an overnight hospitalization for monitoring 
purposes may be considered an SAE but is not necessarily severe.

13.2.2.2. Relationship to Study Intervention 
The Investigator must provide a causality assessment regarding the relationship of the event with 
the study drug and/or study procedure for all AEs.  One of the following categories should be 
selected based on medical judgment, considering all contributing factors: 
• Related: A causal relationship between the medicinal product (and/or study 
procedures) and AE is a reasonable possibility. For example, the occurrence of the 
AE cannot be explained by other causative factors. The AE, however, can be 
explained by pharmacological effect of the medicinal product such as a similar event 
having been reported previously, alteration of the dose effect, or the timing or 
seriousness of the AE, etc. Positive rechallenge/dechallenge is supportive.  
• Not Related: A causal relationship between the medicinal product (and/or study 
procedures) and AE is not a reasonable possibility: there is no temporal relationship 
between the medicinal product and event, or an alternative etiology is more 
reasonable.  
13.2.2.3. Expectedness 
The Sponsor will be responsible for determining whether an adverse event is ‘expected’ or 
‘unexpected’.  An AE will be considered unexpected if the nature, severity, or frequency of the 
event is not consistent with the risk information provided in the Reference Safety Information of 
the effective niraparib Investigator Brochure (IB). 
13.2.3. 
Collection and Recording Adverse Events 
AEs may be volunteered spontaneously by the study patient, or discovered by the study staff 
during physical examinations or by asking an open, nonleading question such as, “How have you 
been feeling since your last study visit?” The Investigator will document the nature of AE, date 
of onset of the AE (and time, if known), date of outcome of the AE (and time, if known), 
severity of the AE, action taken with study drug as a result of the AE, assessment of the 
seriousness of the AE, and assessment of the causal relationship of the AE to study drug and/or 
study procedure. 
AEs, including laboratory abnormalities that are assessed as clinically significant or require 
intervention, should be described using a diagnosis whenever possible, rather than individual 
underlying signs and symptoms. When a clear diagnosis cannot be identified, each sign or 
symptom should be recorded as a separate AE. 
All SAEs will be collected from the signing of the ICF for this study through 90 days after the 
last dose of study drug (or to a minimum of 30 days post treatment if the patient starts alternate 
anticancer therapy and recorded in the eCRF. SAEs will also be reported on an SAE form as 
described in Section 13.2.5 of this protocol. SAEs considered by the Investigator to be related to 
study medication are reported until study closeout. 
All AEs, regardless of the source of identification (e.g., physical examination, laboratory 
assessment, ECG, or reported by patient), will be collected and recorded in the eCRF for each 
patient from the signing of the ICF for this study until 30 days after last study drug 
administration.

Clinical Study Protocol 3000-01-005 Version 2.0 
 
Confidential 
 
Page 59 of 77 
 
 
Concomitant illnesses that existed before entry into the study will not be considered AEs unless 
the illness worsens during the Treatment Period. Pre-existing conditions will be recorded as 
Medical History in the eCRF and on the SAE Report Form. 
Disease progression is an efficacy criterion and is therefore not considered an AE or SAE (even 
if fatal). Disease progression should be reported within the eCRF. If AEs/SAEs occur in relation 
to disease progression that are not consistent with the natural progression of the patient’s disease, 
these AEs/SAEs must be reported per AE/SAE reporting requirements described in 
Section 13.2.5.  
13.2.4. 
Follow-Up of Adverse Events 
All AEs experienced by a patient, regardless of the suspected causality, will be monitored until 
the AE or SAE has resolved, until any abnormal laboratory values have returned to baseline or 
normal levels, until stabilized with a satisfactory explanation for the changes observed, until the 
patient is lost to follow-up, or until the patient has died. 
If an Investigator becomes aware of an SAE after the specified follow-up period and considers 
the SAE related to the study drug, the Investigator should report the SAE to the Sponsor 
according to timelines for reporting SAEs described in Section 13.2.5.   
13.2.5. 
Reporting 
The Investigator must report all SAEs, and all follow up information to the Sponsor on an SAE 
Report Form within 24 hours of becoming aware of the initial event or follow-up information. 
The Investigator must provide a causality assessment and must sign and date all SAE Report 
Forms.   
It is the responsibility of the Investigator to review source documentation and describe pertinent 
information on the SAE Report Form.  If supporting documentation is requested (e.g., hospital 
reports, consultant reports, death certificates, autopsy reports, etc.), the Investigator should 
highlight all relevant and pertinent information within such documents, ensure that any patient’s 
personal identifiers (including Medical Record number) are removed, and submit the documents 
with the SAE Form to the Sponsor. The Sponsor (or designee) will return a confirmation of 
receipt for all email reports (if received from other than a “no reply” domain) within 1 business 
day.  
After receipt of the initial report, the Sponsor (or designee) will review the information and, if 
necessary, contact the Investigator to obtain further information. The Investigator must promptly 
respond to queries from the Sponsor. 
13.2.6. 
Submission and Distribution of Serious Adverse Event Reports 
Per regulatory requirements, if an event is assessed by the Sponsor as a Serious Unexpected 
Adverse Reaction (SUSAR), it is the responsibility of the Sponsor to submit the SUSAR 
Regulatory Authorities according to applicable regulations. 
In addition, the SUSAR will be distributed to the Investigators/sites, utilizing a Council for 
International Organizations of Medical Sciences (CIOMS) report form, or the MedWatch 3500A 
form). The Investigator/site will submit a copy of the report to their respective Institutional

Review Board (IRB) or Independent Ethics Committee (IEC) per the governing institutional 
requirements and in compliance with local laws and guidelines. 
13.2.7. 
Adverse Events of Special Interest 
Adverse Events of Special Interest (AESI) for niraparib are the following:  
• Myelodysplastic Syndromes (MDS) and Acute Myeloid Leukemia (AML) 
• Secondary cancers (new malignancies [other than MDS or AML]) 
• Pneumonitis 
• Embyro-fetal toxicity 
AESI should be collected and reported as follows: 
• MDS and AML along with other secondary cancers should be reported to the Sponsor 
through 90 days after the last dose of study drug. 
• Pneumonitis should be reported to the Sponsor through 90 days after the last dose of 
study drug (or until the start of alternate anticancer therapy, whichever occurs first). 
• Embryo-fetal toxicity should be reported as outlined in Section 13.2.8  
13.2.8. 
Pregnancy  
Pregnancies occurring while female patients are enrolled in a study, or experienced by a female 
partner of a male patient enrolled in a study, must be reported to the Investigator and followed to 
outcome.  Furthermore, all pregnancies must be reported to the Sponsor. The Sponsor has the 
responsibility to monitor the outcome of all pregnancies reported during the clinical study. 
Each pregnancy must be reported by the Investigator to the Sponsor on an Initial Pregnancy 
Report Form within 24 hours of becoming aware of the pregnancy. Pregnancy is not an AE, and 
therefore does not need to be reported as an AE in the eCRF unless there is a suspicion that the 
study drug may have interfered with the effectiveness of a contraceptive medication. The 
Investigator must follow-up all pregnancies, document the course and the outcome, and report 
this information to the Sponsor on a Pregnancy Outcome Report Form within 24 hours of 
becoming aware - even if the patient was withdrawn from the study or the study has finished. 
An elective abortion without complications should not be regarded as an AE, however, it should 
be reported as the outcome to the pregnancy on the Pregnancy Outcome Report Form. 
Therapeutic abortions should be reported as a treatment procedure; the reason for the therapeutic 
abortion should be reported on the Pregnancy Outcome Report Form and as an AE in the eCRF. 
Hospitalization for normal delivery of a healthy newborn should not be considered an SAE. 
Any SAE that occurs during pregnancy must be recorded on the Pregnancy Outcome Report 
Form, reported as an SAE on the SAE Report Form (e.g., maternal serious complications, 
therapeutic abortion, ectopic pregnancy, stillbirth, neonatal death, congenital anomaly, birth 
defect) and reported to the Sponsor within 24 hours. Hospitalization for normal delivery of a 
healthy newborn should not be considered an SAE.

exposure with any study treatment must be reported on a Special Situations Report Form to the 
Sponsor within 5 calendar days of becoming aware of the occurrence, regardless of whether it is 
categorized as an AE. If the occurrence is associated with an SAE, an SAE Report Form, along 
with the Special Situations Report Form, must be submitted to the Sponsor within 24 hours of 
awareness.

STATISTICS 
Details of the statistical analyses presented below will be provided in the Statistical Analysis 
Plan (SAP). A change to the data analysis methods described in the protocol will require a 
protocol amendment only if it alters a principal feature of the protocol. The SAP will be finalized 
prior to database lock. Any changes to the methods described in the plan will be described and 
justified in the final clinical study report. 
No formal statistical testing will be done for this study. Data will be summarized in a descriptive 
nature. Categorical variables will be summarized by frequency distributions (number and 
percentage of patients). Continuous variables will be summarized by the mean, standard 
deviation, median, minimum, maximum, first quartile and third quartile. Further details will be 
provided in the SAP. 
14.1. 
Sample size determination 
No formal sample size calculation has been done for this study. The sample size is determined 
based on the clinical considerations only.  
A total of approximately 20 evaluable patients will be enrolled. This sample size should be 
sufficient for signal finding prior to initiating a larger study. For example, it will provide 
approximately 80% power with 1-sided significance level of 0.15 to differentiate a response rate 
of 80% from a minimum response rate of 60%. Other examples are provided below.

v4.03 will be used to grade the severity of AEs and laboratory abnormalities. Prior/concomitant 
medication and anticancer treatment will be coded using the World Health Organization 
Anatomical Therapeutic Chemical classification system. 
AEs will include the following categories: 
• TEAEs 
− Drug-related TEAEs 
− Grade 3, 4, and 5 TEAEs (presented by grade and overall) 
− Grade 3,4, and 5 drug-related TEAES (presented by grade and overall) 
− TEAEs resulting in study drug discontinuation 
− Most commonly reported TEAEs (ie, those events reported by ≥10% of all 
patients) 
− Treatment-emergent SAEs 
• AESIs 
Details for the safety analysis will be specified in the Statistical Analysis Plan.

DIRECT ACCESS TO SOURCE DATA/DOCUMENTS 
15.1. 
Study Monitoring 
Before an investigational site can enter a patient into the study, a representative of TESARO will 
visit the investigational study site to: 
• Determine the adequacy of the facilities 
• Discuss with the Investigator(s) and other personnel their responsibilities with regard to 
protocol adherence, and the responsibilities of TESARO or its representatives. This will 
be documented in a Clinical Study Agreement between TESARO and the Investigator.

Page 64 of 77 
 
 
During the study, a monitor from TESARO or representative will have regular contacts with the 
investigational site, for the following: 
• Provide information and support to the Investigator(s) 
• Confirm that facilities remain acceptable 
• Confirm that the investigational team is adhering to the protocol, that data are being 
accurately recorded in the case report forms, and that investigational product 
accountability checks are being performed 
• Perform source data verification. This includes a comparison of the data in the case report 
forms with the patient’s medical records at the hospital or practice, and other records 
relevant to the study. This will require direct access to all original records for each patient 
(e.g., clinic charts). 
• Record and report any protocol deviations not previously sent to TESARO 
• Confirm AEs and SAEs have been properly documented on CRFs and confirm any SAEs 
have been forwarded to TESARO and those SAEs that met criteria for reporting have 
been forwarded to the IRB. 
The monitor will be available between visits if the Investigator(s) or other staff needs 
information or advice. 
15.2. 
Audits and Inspections 
Authorized representatives of TESARO, a regulatory authority, an Independent Ethics 
Committee or an Institutional Review Board may visit the site to perform audits or inspections, 
including source data verification. The purpose of a TESARO audit or inspection is to 
systematically and independently examine all study-related activities and documents to 
determine whether these activities were conducted, and data were recorded, analyzed, and 
accurately reported according to the protocol, Good Clinical Practice (GCP) guidelines of the 
International Conference on Harmonization, and any applicable regulatory requirements. The 
Investigator should contact TESARO immediately if contacted by a regulatory agency about an 
inspection. 
15.3. 
Institutional Review Board  
The PI must obtain IRB approval for the investigation. Initial IRB approval, and all materials 
approved by the IRB for this study including the patient consent form and recruitment materials 
must be maintained by the Investigator and made available for inspection.

ETHICS 
17.1. 
Ethics Review 
The final study protocol, including the final version of the Informed Consent Form, must be 
approved or given a favorable opinion in writing by an IRB or IEC as appropriate. The 
Investigator must submit written approval to TESARO before he or she can enroll any 
patient/patient into the study. 
The PI is responsible for informing the IRB or IEC of any amendment to the protocol in 
accordance with local requirements. In addition, the IRB or IEC must approve all advertising 
used to recruit patients for the study. The protocol must be re-approved by the IRB or IEC upon 
receipt of amendments and annually, as local regulations require. 
The PI is also responsible for providing the IRB with reports of any reportable serious adverse 
drug reactions from any other study conducted with the investigational product. TESARO will 
provide this information to the PI. 
Progress reports and notifications of serious adverse drug reactions will be provided to the IRB 
or IEC according to local regulations and guidelines. 
17.2. 
Ethical Conduct of the Study 
The study will be performed in accordance with ethical principles that have their origin in the 
Declaration of Helsinki and are consistent with International Council for Harmonization/Good 
Clinical Practice, applicable regulatory requirements and the TESARO’s policy on Bioethics. 
17.3. 
Written Informed Consent 
The PI(s) at each center will ensure that the patient is given full and adequate oral and written 
information about the nature, purpose, possible risk and benefit of the study. Patients must also 
be notified that they are free to discontinue from the study at any time. The patient should be 
given the opportunity to ask questions and allowed time to consider the information provided. 
The patient’s signed and dated informed consent must be obtained before conducting any study 
procedures. 
The PI(s) must maintain the original, signed Informed Consent Form. A copy of the signed 
Informed Consent Form must be given to the patient.

APPENDIX 2. DISEASE ASSESSMENT CRITERIA  
 
Definition of response  
Response will be assessed by imaging tests (ultrasound and MRI). Disease assessment is to be 
determined by changes in the tumor volume, calculated as length × width × height × π)/6. While 
all measurable lesions will be followed in cases multifocal or multicentric disease, only the 
largest or primary lesion will be used for assessing disease status as follows: 
• Clinical complete response (CR) 
Complete disappearance of all tumor signs in the breast as assessed by imaging test. The 
response of the axillary nodes is not to be considered. 
• Clinical partial response (PR) 
Reduction in the tumor volume of the primary tumor size by ≥30% assessed by palpation 
or imaging test. In patients with multifocal or multicentric disease, the lesion with the 
largest volume should be chosen for follow-up. The response of the axillary nodes is not 
to be considered. 
• Clinical stable disease (SD) 
No significant change in tumor volume during treatment. This category includes no 
change, an estimated reduction of the tumor volume of the primary lesion by less than 
30%, or an estimated increase in the size of the tumor volume of less than 20% measured 
imaging test. 
• Clinical progressive disease (cPD) 
Development of new, previously undetected lesions, or an estimated increase in the size 
of the primary lesion by greater than 20%.

TERMINOLOGY CRITERIA FOR ADVERSE EVENTS 
 
Refer to NCI CTCAE v.4.03 in the Study Reference Manual, or online at the following NCI 
website: http://ctep.cancer.gov/reporting/ctc.html 
 
1. Toxicity grade should reflect the most severe degree occurring during the evaluated 
period, not an average. 
2. When two criteria are available for similar toxicities, the one resulting in the more severe 
grade should be used. 
3. The evaluator must attempt to discriminate between disease/treatment and related 
signs/symptoms. 
 
An accurate baseline prior to therapy is essential.

INTRODUCTION 
This statistical analysis plan (SAP) provides the detailed statistical methods to be used for 
analyses and data presentation for reporting efficacy and safety of investigational drug niraparib 
for TESARO study protocol 3000-01-005.  
The pharmacokinetics and exposure-response analyses will be provided in a separate document. 
The exploration of blood and tumor-based biomarkers that predict sensitivity or resistance to 
niraparib will also be detailed in a separate document.  
This document has been prepared according to Study Protocol Version 2 dated 01 August 2018.

STUDY DESIGN OVERVIEW 
2.1 
Overall Study Design 
This is an open-label, single-arm pilot study evaluating the antitumor activity and safety of 
niraparib as neoadjuvant therapy in patients with human epidermal growth factor receptor 2 
(HER2) negative and breast cancer susceptibility gene mutant (BRCAmut) localized breast cancer 
(primary tumor ≥1 cm). The study design is summarized in the schema below. If antitumor 
activity in the BRCAmut cohort is demonstrated, the protocol may be amended to add a 
homologous recombination deficiency (HRD)-positive, BRCA-wild type cohort.  The study 
design is presented graphically as below.

This study will consist of a Screening Period (Day -28 to Day -1), a Treatment Period, Presurgery 
chemotherapy (if appropriate), Surgery, a Safety Follow-up/EOT visit occurring 30 days (+ 7 days) 
after the last dose of study medication, and an Off-Study Visit for the purposes of collecting the 
pathological complete response (pCR) results for patients for whom the Safety Follow-up/EOT Visit 
occurred prior to surgery; for all other patients the Safety Follow-up/EOT Visit will act as the off-study 
visit.  
 The schedules of assessments are presented in Table 1.

1 If BRCA status is known, it need not be repeated. Results may have been obtained by either local or central laboratory testing.  
2 Can be collected pre-dose Day 1 of the next cycle.  
3 Pre-surgery blood sample is not required for patients proceeding directly to surgery at the end of Cycle 2.  
4 Can be performed +/- 3 days from Day 28, but results must be available prior to the start of the next cycle.  
5 Core biopsy should be obtained on Cycle 2 Day 28 (+7 days) within 24 hours of last dose of niraparib and prior to ultrasound, MRI, and any subsequent anticancer therapy 
or procedure. A surgical biopsy may be used in lieu of a core biopsy provided that surgery occurs within 24 hours of the last dose of niraparib in Cycle 2.  
6 Cycle 1 Day 1 testing not required if screening assessments were performed within 72 hours of Day 1.  
7 A serum pregnancy test will be performed locally for all women of childbearing potential at Screening (within 72 hours prior to the first dose of study drug). The result 
must be negative before the first dose of study drug is administered. If the serum pregnancy result is not available before dosing, a urine pregnancy test may be performed. 
Pregnancy tests may also be repeated during the study if requested by an IEC/IRB or if required by local regulations. 
8 SAEs and AESIs concerning hypertension and hematologic toxicities will be collected and recorded in the eCRF and on an SAE report form for each patient from the 
date of signed informed consent until 90 days after the last dose of study drug (or until the start of alternate anticancer therapy, whichever occurs first). AESIs 
concerning MDS/AML, secondary cancers, pneumonitis, and embryo-fetal toxicity must be collected and reported to the Sponsor for each patient from the date of 
signed informed consent until study closeout.  
9 Samples for PK assessment with be collected on Day 1 of Cycles 1 and 2 predose, 2 (± 30 minutes) and 4 (± 30 minutes) hours post dose, and in conjunction with the post-
treatment core biopsy.

Sample Size 
No formal sample size calculation has been done for this study. The sample size is determined 
based on the clinical considerations only.  
A total of approximately 20 evaluable patients will be enrolled. This sample size should be 
sufficient for signal finding prior to initiating a larger study. For example, it will provide 
approximately 80% power with 1-sided significance level of 0.15 to differentiate a response 
rate of 80% from a minimum response rate of 60%. Other examples are provided below in

STUDY OBJECTIVES 
3.1 
Primary Objective 
The primary objective of this study is:  
• To evaluate the preliminary antitumor activity of niraparib assessed as the tumor 
response rate based on the change in tumor volume as measured by breast MRI, 
observed after treatment with niraparib in the neoadjuvant treatment of localized, 
HER2 negative, breast cancer susceptibility gene mutant (BRCAmut) breast cancer 
patients.  
3.2 
Second Objectives 
The secondary objectives of the study are as follows:  
• To evaluate the preliminary antitumor activity of niraparib assessed by:  
- Presence of pCR defined as ypT0/Tis ypN0 by receipt of pre-operative 
chemotherapy (Yes versus No)  
- Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment by MRI and ultrasound 
- Tumor response rate based on the change in tumor volume as measured by 
breast ultrasound  
• To evaluate safety and tolerability of niraparib per National Cancer Institute-Common 
Terminology Criteria for Adverse Events (NCI-CTCAE) v4.03 criteria  
3.3 
Exploratory Objectives 
• To evaluate niraparib-induced changes in immune responses  
•  To explore intra-tumoral niraparib concentration and correlation with blood  
• To estimate the preliminary antitumor activity of niraparib in BRCAmut triple-
negative breast cancer (TNBC) patients and BRCAmut hormone-positive (HR+) 
patients  
• To evaluate pharmacodynamic inhibition of poly(ADP-ribose) polymerase (PARP) 
activity in the tumor  
• To explore molecular biomarkers related to disease biology or response to treatment 
using tumor tissue or liquid biopsy approaches (e.g. ctDNA)

STUDY ENDPOINTS AND EVALUATIONS 
4.1 
Efficacy Endpoints 
4.1.1 Primary Efficacy Endpoint 
Tumor response rate based on the change in tumor volume as measured by breast MRI; a 
response is considered at least >30% reduction of tumor volume from baseline after 2 months 
of niraparib treatment without any new lesion development. Tumor volume will be calculated 
as (length × width × height × π)/6. The percentage reduction in tumor volume will be set as 
99% if the tumor becomes too small to measure at the post-baseline visit. 
4.1.2 Secondary Efficacy Endpoints 
• pCR is defined as ypT0/Tis ypN0 by receipt of pre-operative chemotherapy (Yes vs. 
No). pCR is defined as the absence of residual invasive cancer on hematoxylin and 
eosin evaluation of the complete resected breast specimen and all sampled regional 
lymph nodes following completion of neoadjuvant systemic therapy (i.e., ypT0/Tis 
ypN0 in the current AJCC staging system [Appendix D]).  
• Tumor response rate based on the change in tumor volume as measured by breast 
ultrasound; a response is considered at least >30% reduction of tumor volume from 
baseline after 2 months of niraparib treatment without any new lesion development. 
Tumor volume will be calculated as (length × width × height × π)/6.  
• Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment as measured by ultrasound. Tumor volume will be calculated as (length × 
width × height × π)/6. The percentage reduction in tumor volume will be set as 99% if 
the tumor becomes too small to measure at the post-baseline visit.  
• Percentage change in tumor volume from baseline after 2 months of niraparib 
treatment as measured by MRI. Tumor volume will be calculated as (length × width × 
height × π)/6. The percentage reduction in tumor volume will be set as 99% if the 
tumor becomes too small to measure at the post-baseline visit.  
4.1.3 Exploratory Efficacy Endpoints 
• Immune-related changes in gene expression profiles and cellular composition (eg, T-
cells, myeloid cells, and natural killer cells) in pre vs. post niraparib treatment tumor 
samples  
• Niraparib concentration in post treatment tumor samples and correlation with PK in 
peripheral blood  
• Estimation of change in tumor volume in BRCAmut TNBC patients and in BRCAmut 
hormone-positive patients

Patient Enrolment and Disposition 
7.2.1 Patient Enrollment  
Number of patients will be provided for each analysis population.  For the Safety population, 
the denominators for percentages are based on number of screened patients. Screened 
population includes all patients who have been consented. 
For other populations, the denominators for percentages are based on number of patients in 
the Safety population. 
Enrollment information will be provided in a data listing. 
7.2.2 Patient Disposition 
Patient disposition will be summarized for the Safety population. The summary will present 
frequency distribution for patients completing the study and discontinuing from the study 
overall and by reason for discontinuation.   
Additionally, the frequency distribution will be provided for patients discontinuing treatment 
niraparib by reason for discontinuation.  
The denominators for calculating the percentages will be based on number of patients in the 
Safety population.  
Discontinued patients will be provided in a data listing. 
7.2.3 Protocol Deviations 
A protocol deviation (PD) is any failure to comply with the study protocol as approved by the 
relevant regulatory authority, ethics committee and/or institutional review board, whether 
planned or unplanned.  
 
PD will be assessed and classified as important or significant. A protocol deviation is 
classified as an important PD if there is the potential to:  
• Impact the completeness, accuracy, and/or reliability of the study data, or

• Affect a subject's rights, safety, or well-being.  
 
Important protocol deviations require review to confirm whether or not they are significant. 
The following are PDs that will always be considered important according to TESARO SOP 
1000-00021-CLN:  
• Failure to obtain informed consent for participation in the clinical trial  
• Enrollment of ineligible subject  
• Subject developed withdrawal criteria during the study but was not withdrawn  
• Subject received incorrect treatment  
• Incorrect or non-compliant dosing of a subject, i.e. dosing that is inconsistent with the 
protocol  
• Administration of an excluded concomitant treatment to a trial subject  
• Incorrect cohort assignment  
 
A protocol deviation is classified as a significant PD if it has been confirmed to:  
• Adversely impact the completeness, accuracy, and/or reliability of the study data  
• Affect a subject’s rights, safety, or well-being.  
 
The TESARO medical monitor in conjunction with other study team members as appropriate 
may determine any PD not listed above to be important or significant based on his/her 
assessment of (potential) impact. Additionally, a PD could be “downgraded.” In this case, the 
rationale for the change should be documented by the TESARO medical monitor.  
 
Criteria for important and/or significant PDs may be updated as needed throughout the 
course of the clinical trial. 
All PDs will be identified and finalized prior to database lock. 
Number and percentage of patients with important or significant protocol deviations will be 
summarized by type of deviation. The denominators for calculating the percentages will be 
based on number of patients in the Safety population.  
All protocol deviations will be listed.

preexisting condition that worsens in severity after the first dose of study treatment.   
The number and percentage of patients who experienced an AE will be summarized. The 
denominator for calculating the percentages will be based on the number of patients in the 
safety population.

statistics. Details of study drug administration, dose modifications and duration of exposure 
will be listed. 
7.7.3 
Clinical Laboratory Evaluations 
Clinical laboratory assessments (CBC and serum chemistry) will be summarized by visit in 
descriptive nature. Descriptive statistics will be provided for continuous laboratory data and 
associated change from baseline. Frequency distribution will be provided for categorical 
laboratory.  
The worst toxicity grades for selected laboratory tests as listed in Appendix B (Table 4) will 
be determined for each patient based on worst abnormal high and abnormal low lab values.  
The shift table from baseline CTCAE grade to the worst NCI CTC grade will be provided. 
Laboratory measurements that are within their institutional limits of normal and are not 
graded as 1-4, per the CTCAE, will be summarized as “Grade 0,” which is defined as normal. 
Additionally, if a lab parameter is graded in both directions (e.g. glucose: hyperglycemia and 
hypoglycemia), then low direction toxicity grades at baseline and post baseline will be set to 
0 when the variables are derived for summarizing high direction toxicity, and vice 
versa.  Hyperglycemia will only be coded to grades ≥ 3 using non-fasting glucose and 
therefore will not be included in shift tables. 
For shift table from baseline to post-baseline visit, the denominators for calculating the 
percentages will be based on the number of patients with non-missing values at both baseline 
and post-baseline analysis visit in the Safety population.

DEFINITIONS AND CONVENTIONS FOR DATA HANDLING  
As a general rule, missing data values are not imputed unless otherwise specified below and, 
in presentation of categorical variables, unknown and missing data may be presented as a 
separate category in some case and the denominator will include unknown or missing values 
as appropriate. 
8.1 
Definition of Baseline 
For all evaluations unless otherwise noted, baseline is defined as the most recent 
measurement prior to the first administration of study drug. Baseline can be the same date as 
first dose, given the measurement is expected prior to first dose when only date information 
is available. 
8.2 
Analysis Visit Window 
For safety parameters excluding clinical laboratory data, measurements collected from 
unscheduled visits will not be included in the by-visit summary tables but will be included in 
the listings.  
8.3 
Efficacy Data Handling 
See Section 4.1.1 and 4.1.2 of the SAP. 
8.4 
Safety Data Handling 
For all safety data, only observed data will be used for analyses, and missing data will not be 
imputed. 
8.4.1 
Handling of Repeated Clinical Laboratory Tests 
The last repeat of laboratory results will be used in the summary tables for that visit. All the 
laboratory test results (original test results and repeated results) will be included in the data 
listings. 
8.4.2 
Handling of Partial Dates for AEs   
When determining the treatment emergent AE, partial dates will be handled as follows.

• If the day of the month is missing, the onset day will be set to the first day of the month 
unless it is the same month and year as study treatment. In this case, the onset date will be 
assumed to be the date of treatment. 
• If the onset day and month are both missing, the month and day will be assumed to be 
January 1 unless the event occurred in the same year as the study treatment. In this case, 
the event onset will be set to the day of treatment to conservatively report the event as 
treatment-emergent.  
• A completely missing onset date will be set as the day of treatment. If the resulting onset 
date is after a reported date of resolution, the onset date will be set equal to the date of 
resolution.   
• Imputation of partial dates is used only to determine whether an event is treatment-
emergent; data listings will present the partial date as recorded in the eCRF. 
8.4.3 
Handling of Partial Dates for Medications  
A medication with a completely missing start date will be considered a prior medication. A 
medication with a completely missing stop date will be considered a concomitant medication.   
When determining prior or concomitant medications, partial start dates of prior and 
concomitant medications will be assumed to be the earliest possible date consistent with the 
partial date. Partial stop dates of prior and concomitant medications will be assumed to be the 
latest possible date consistent with the partial date. In the case of completely missing stop 
date, medication will be assumed to be ongoing. In the case of complete missing start date, 
medication will be assumed to be prior medication.

10 APPENDICE 
Appendix A. Disease Assessment Criteria 
Response will be assessed by imaging tests (ultrasound and MRI). Disease assessment is to 
be determined by changes in the tumor volume, calculated as length × width × height × π)/6. 
While all measurable lesions will be followed in cases multifocal or multicentric disease, 
only the largest or primary lesion will be used for assessing disease status as follows: 
• Clinical complete response (CR) 
Complete disappearance of all tumor signs in the breast as assessed by imaging test. The 
response of the axillary nodes is not to be considered. 
• Clinical partial response (PR) 
Reduction in the tumor volume of the primary tumor size by 30% or more assessed by 
palpation or imaging test. In patients with multifocal or multicentric disease, the lesion 
with the largest volume should be chosen for follow-up. The response of the axillary 
nodes is not to be considered. 
• Clinical stable disease (SD) 
No significant change in tumor volume during treatment. This category includes no 
change, an estimated reduction of the tumor volume of the primary lesion by less than 
30%, or an estimated increase in the size of the tumor volume of less than 20% measured 
imaging test. 
• Clinical progressive disease (cPD) 
Development of new, previously undetected lesions, or an estimated increase in the size 
of the primary lesion by 20% or more.
