Inclusion Criteria:
1. Volunteers must have clinical and radiographic evidence of newly detected FIGO stage
II, III or IV epithelial ovarian, primary peritoneal or fallopian tube cancer, deemed
by a gynecologic oncologist as not amenable to an R0 resection at presentation.
2. Institutional confirmation of Müllerian epithelial adenocarcinoma
3. Histologic epithelial cell types: high grade serous carcinoma, high grade endometrioid
carcinoma, or a combination of these.
4. Documented mutation in BRCA1 or BRCA2 by genetic or commercial somatic testing.
Reports will require submission at the time of enrollment.
5. Measurable disease as defined by RECIST 1.1. Measurable disease is defined as at least
one lesion that can be accurately measured in at least one dimension (longest diameter
to be recorded). Each lesion must be ≥ 10 mm when measured by CT, MRI or caliper
measurement by clinical exam; or ≥ 20 mm when measured by chest x-ray. Lymph nodes
must be ≥ 15 mm in short axis when measured by CT or MRI.
6. Age ≥ 18
7. Female sex at birth
8. Adequate hematologic function determined within 28 days of consent as follows:
- ANC greater than or equal to 1,500/mcl. NOTE: ANC cannot have been induced by
granulocyte colony stimulating factors.
- Platelets greater than or equal to 100,000/mcl
- Hemoglobin greater than 10 mg/dl (transfusions are permitted to achieve baseline
hemoglobin level. Note: may not have transfusion within 14 days prior to
obtaining baseline screening labs)
9. Serum Creatine<1.5 ULN
10. Adequate hepatic function within 14 days prior to registration defined as follows:
- Bilirubin ≤ 1.5 x ULN
- ALT and AST ≤ 2.5 x ULN
- Alkaline phosphatase ≤ 2.5 x ULN
11. Neurologic function: Neuropathy (sensory and motor) less than or equal to CTCAE Grade
1.
12. Ability to swallow and retain oral medication. Adequate gastrointestinal absorption
with no use of parenteral nutrition within two weeks of trial enrollment and no
evidence of bowel obstruction.
13. The volunteer must provide study-specific informed consent prior to study entry.
Exclusion Criteria:
1. Suspected non-gynecologic malignancy, evidence by tumor markers and/or histologic
evaluation.
2. Prior history of other invasive malignancies, with the exception of nonmelanoma skin
cancer and other specific malignancies are excluded if there is any evidence of other
malignancy being present within the last three years (2 years for breast cancer).
Volunteers are also excluded if their previous cancer treatment contraindicates this
protocol therapy.
3. Prior chemotherapy for any abdominal or pelvic tumor within the last three years is
excluded. Volunteers may have received prior adjuvant chemotherapy and radiotherapy
for localized breast cancer, provided that it was completed more than 2 years prior to
registration, the volunteer remains free of recurrent or metastatic disease and
hormonal therapy has been discontinued.
4. Prior radiotherapy to any portion of the abdominal cavity or pelvis or thoracic cavity
within the last three years are excluded. Prior radiation for localized cancer of the
head and neck or skin is permitted, provided that it was completed more than three
years prior to registration, and the volunteer remains free of recurrent or metastatic
disease.
5. Synchronous primary endometrial cancer, or a past history of primary endometrial
cancer, unless all of the following conditions are met: Stage not greater than I-A,
grade 1 or 2, no more than superficial myometrial invasion, without vascular or
lymphatic invasion; no poorly differentiated subtypes, including serous, clear cell or
other FIGO grade 3 lesions.
6. Severe, active co-morbidity defined as follows:
- Chronic or current active infectious disease requiring systemic antibiotics,
antifungal or antiviral treatment
- Known brain or central nervous system metastases or history of uncontrolled
seizures
- Clinically significant cardiac disease including unstable angina, acute
myocardial infarction within 6 months from enrollment, New York Heart Association
Class III or IV congestive heart failure, and serious arrhythmia requiring
medication (this does not include asymptomatic atrial fibrillation with
controlled ventricular rate).
- Partial or complete gastrointestinal obstruction
7. Volunteers who are not candidates for major abdominal surgery due to known medical
comorbidities.
8. Volunteers with any condition that in the judgment of the investigator would
jeopardize safety or volunteer compliance with the protocol.
9. Concurrent anticancer therapy (e.g. chemotherapy, radiation therapy, biologic therapy,
immunotherapy, hormonal therapy, investigational therapy).
10. Receipt of an investigational study drug for any indication within 30 days or 5
half-lives (whichever is longer) prior to Day 1 of protocol therapy.
11. No prior exposure to a PARP inhibitor.
- The criteria for premenopausal women are as follows:
- Any female who has experienced menarche and who has not undergone surgical
sterilization (hysterectomy and/or bilateral oophorectomy) or who is not
postmenopausal. Menopause is defined clinically as 12-month amenorrhea in a woman
over 45 in the absence of other biological or physiological causes.
- Volunteers who are pregnant or nursing. Volunteers must agree to use adequate
contraception (hormonal or barrier method of birth control; abstinence) prior to
study entry, for the duration of study participation, and for at least 7 months
after completing therapy.
- WOCBP must have a screening negative serum or urine pregnancy test within 14 days
of registration. A second pregnancy test must be done within 24 hours prior to
the start of the first cycle of study treatment.
