| Eligibility |
Inclusion Criteria:
- Patients PRE-identified as having either a germline deleterious mutation or tumor
expression of a deleterious mutation) as determined by Next-generation DNA sequencing
only, in at least one gene involved in DNA damage repair through homologous
recombination including but not limited to: ARID1A, ATM, ATRX, MRE11A, NBN, PTEN,
RAD50/51/51B, BARD1, BLM, BRCA1, BRCA2, BRIP1, FANCA/C/D2/E/F/G/L, PALB2, WRN, CHEK2,
CHEK1, BAP1, FAM175A, SLX4, MLL2 or XRCC.
- Patients with somatic mutations will be PRE-identified as having a homologous
recombination mutation based on NGS done in a CLIA certified, CAP tested and
bioinformatics-validated testing lab PRIOR to enrollment in this current protocol. The
testing may have been done at any time prior to enrollment. HOWEVER, if any patient
has had NGS testing more than 3 months prior to enrollment, or if there has been
intervening therapy, then a repeat NGS test must be done and the deleterious somatic
mutation must be re-identified for inclusion.
- The determination of a deleterious mutation must be supported in the documentation
included in the testing, and should include clinical, or pre-clinical literature to
support the finding that a specific mutation results in impaired function of the gene,
and thus impaired DNA repair through homologous recombination. Variants of unknown
significance will not be eligible.
- Patients with germline deleterious mutations may have been identified at any time
point prior to inclusion in the protocol and do NOT need to have this genetic testing
repeated regardless of time frame and intervening therapy.

image on computed tomography (CT) or magnetic resonance imaging (MRI) and/or lymph
node(s) = 1.5 cm in short axis on CT or MRI) on baseline imaging
- ECOG performance status (PS) of 0 to 1 (Table 10, Appendix A)
- Patients who have received and failed, or have been intolerant to, standard first line
therapies known to confer clinical benefit. Patients who refuse standard therapy would
also be eligible, as long as their refusal is documented.
- Patients with a standard 12-lead electrocardiogram (ECG) with the following parameters
at screening (defined as the mean of the triplicate ECGs):
1. QTc interval at screening < 481 msec
2. Resting heart rate 50-90bpm

- Bone Marrow: Absolute neutrophil count (ANC) = 1,500/mm3; Platelets = 100,000/mm3;
Hemoglobin = 9.0 g/dL. Patients must be able to meet the criteria without transfusion
or receipt of colony stimulating factors within 2 weeks before obtaining sample
- Renal function: Serum creatinine = 2.0 mg/dL OR creatinine clearance = 50 mL/min/1.73
m2
- Hepatic function: aspartate aminotransferase (AST) and alanine aminotransferase (ALT)
= 2.5 × the upper normal limit of institution's normal range. Total bilirubin = 1.5 ×
the upper normal limit of institution's normal range. For subjects with liver
metastases, AST and ALT < 5 × the upper normal limit of institution's normal range,
and total bilirubin >1.5 - 3.0 x the upper normal limit of institution's normal range
are acceptable as long as there is no persistent nausea, vomiting, right upper
quadrant pain or tenderness, fever, rash, or eosinophilia
- Prothrombin Time (PT) and Partial Thromboplastin Time (PTT) must be = 2 X the upper
limit of the institution's normal range and International Normalized Ratio (INR) < 2.
Subjects on anticoagulation (such as coumadin) will be permitted to enroll as long as the
INR is in the acceptable therapeutic range as determined by the investigator
- Patients may have received an unlimited number of prior therapies
- Patients must have fully recovered from all effects of surgery. Patients must have had
at least two weeks after minor surgery and four weeks after major surgery before
starting therapy. Minor procedures requiring conscious sedation such as endoscopies or
mediport placement may only require a 24-hour waiting period, but this must be
discussed with an investigator
- Women of childbearing potential must have a negative serum pregnancy test within 14
days prior to initiation of treatment and/or postmenopausal women must be amenorrheic
for at least 12 months to be considered of non-childbearing potential
- Patient is capable of swallowing pills whole
- Subject is capable of understanding and complying with parameters as outlined in the
protocol and able to sign and date the informed consent, approved by the IRB, prior to
the initiation of any screening or study-specific procedures
Exclusion Criteria:
- Prior disease progression while receiving platinum chemotherapy or platinum
chemotherapy within the last 6 months
- For patients who received platinum-based adjuvant chemotherapy, at least 6 months must
have passed between the last dose of platinum-based therapy and the development of
metastatic disease. For breast cancer patients, at least 12 months must have passed
between the last dose of platinum-based therapy and the development of metastatic
disease
- Prior PARP inhibitor-based therapy
- Known or suspected CNS metastases, unless at least one month has passed since last
local CNS therapy and there is no evidence for recurrent or progressive CNS disease on
follow up imaging. Participants may remain on steroids for CNS disease if they are
taking a stable dose
- Active severe infection, or known chronic infection with HIV or hepatitis B virus
(testing not required prior to enrollment)
- Patients with chronic Hepatitis C virus may be enrolled if there is no
clinical/laboratory evidence of cirrhosis AND the patient's liver function tests fall
within the parameters set in Section 3.2.8.3, Inclusion Criteria, Hepatic function
- Cardiovascular disease problems including unstable angina, therapy for
life-threatening ventricular arrhythmia, or myocardial infarction, stroke, or
congestive heart failure within the last 6 months. Additionally, patients must not
have QT prolongation greater than or equal to 481 milliseconds
- Life-threatening visceral disease or other severe concurrent disease that would, in
the investigator's judgment, cause unacceptable safety risks, contraindicate patient
participation in the clinical study or compromise compliance with the protocol (e.g.
chronic active hepatitis, active untreated or uncontrolled fungal, bacterial or viral
infections, etc.)
- Patient has impairment of gastrointestinal (GI) function or GI disease that may
significantly alter the absorption of the study drugs (e.g., ulcerative diseases,
uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel
resection)
- Presence of a psychiatric illness or social situation that would limit compliance with
study requirements
- Women who are pregnant or breastfeeding
- The subject must not have had diagnosis, detection, or treatment of another type of
cancer =2 years prior to randomization (except basal or squamous cell carcinoma of the
skin that has been definitively treated). Questions regarding the inclusion of
individual subjects should be directed to the Principal Investigators, Dr. Isaacs and
Dr. Pishvaian.

NCI CTCAE v4.0) as grade 2 or greater neurosensory or neuromotor toxicity)
- Patients must not have had investigational therapy administered =4 weeks, or within a
time interval less than at least 5 half-lives of the investigational agent, whichever
is longer, prior to the first scheduled day of dosing in this study
- Patients must not have had radiotherapy encompassing >20% of the bone marrow
- Patients must not have a known hypersensitivity to the components of niraparib or the

- Patients must not have had any known, persistent > Grade 2 toxicity from prior cancer
therapy
- Patient must not have had any known, persistent (>4 weeks), =Grade 3 hematological
toxicity or fatigue from prior cancer therapy
- Patients must not have current evidence of any condition, therapy, or laboratory
abnormality (including active or uncontrolled myelosuppression [ie, anemia,
leukopenia, neutropenia, thrombocytopenia]) that might confound the results of the
study or interfere with the patient's participation for the full duration of the study
treatment or that makes it not in the best interest of the patient to participate
- Patients must not be considered a poor medical risk due to a serious, uncontrolled
medical disorder, nonmalignant systemic disease, or active, uncontrolled infection.
Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent
(within 90 days) myocardial infarction, uncontrolled major seizure disorder, unstable
spinal cord compression, superior vena cava syndrome, or any psychiatric disorder that
