A Pharmacokinetic/Pharmacodynamic Study With a Phase I Run-In With a PARP Inhibitor (Olaparib) in Combination With Carboplatin for Refractory or Recurrent Women's Cancers

Inclusion Criteria

- INCLUSION CRITERIA:

- Patients must have confirmed at the NCI, histologically or cytologically
recurrent/refractory gynecologic cancers such as but not restricted to epithelial
ovarian, fallopian, primary peritoneal, uterine papillary serous cancer, cervix
cancer, malignant mixed mullerian tumors, or any type of breast cancer that is
metastatic or unresectable and for whom curative therapies do not exist.

- All patients must have measurable and/or evaluable disease; biomarker-only disease is
not considered measurable or evaluable; eligibility of bone only disease is a PI
decision on an individual patient basis.

- Breast cancer patients with locally advanced, unresectable disease must have been
previously treated with standard therapy.

- Breast cancer patients with deleterious mutation in DNA repair enzymes with locally
advanced or metastatic disease do not have to have had prior therapy for their
progressive disease. Men with BRCA1/2 mutation and metastatic breast cancer will be
eligible for study. Ovarian or endometrial cancer patients with deleterious mutation
in DNA repair enzymes may be treated in first recurrence independent of
platinum-sensitivity history.

- There is no limit on number of prior therapies. Patients must be at least 6 months
from their last platinum exposure and platinum-resistant patients may participate.

- Age greater than or equal to 18 years

- ECOG performance status less than or equal to 2

- Patients must have normal organ and marrow function as defined below:

Absolute neutrophil count greater than or equal to 1,500/mm3

Platelets greater than or equal to 100,000/mm3

Serum Creatinine less or than or equal to 1.5 mg/dL or if low, Cr Cl greater than 60
mL/min

Total bilirubin less than or equal to 1.5 times the limit of normal (ULN) in the absence
of Gilbert's syndrome

AST(SGOT0/ALT(SGPT) less than or equal to 3 times the ULN (CTCAE4.0 grade 2)

- Women of child-bearing potential 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 three months following the last
dose of experimental therapy.

- Women of childbearing potential must have a negative urine or serum pregnancy test
within 7 days prior to the start of the study.

- Ability to understand and the willingness to sign a written informed consent document

- Inclusion of Women and Minorities: Women and members of all races and ethnic groups
are eligible for this trial.

EXCLUSION CRITERIA:

- Patients who have had treatment for their disease, such as chemotherapy, biological
therapy, radiotherapy, surgery, or complementary and alternative therapy within 4
weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study.

- Patients who were treated with other PARP inhibitors greater than 28 days prior to
study are eligible.

- Must be at least 2 weeks from the last phase 0 intervention (longer at the discretion
of the PI) and at least 1 day from non-cancer-related complementary and alternative
medicine prior to entering the study.

- Previous treatment with olaparib (AZD2281).

- Invasive cancer, other than co-existent breast/gynecologic cancers, within the past 2
years. Noninvasive nonmelanoma skin cancers are not exclusions.

- Patients with known brain metastases diagnosed within 1 year will be excluded from
this clinical trial because of their poor prognosis and because they often develop
progressive neurologic dysfunction that would confound the evaluation of neurologic
and other adverse events.

- Patients with brain metastases diagnosed greater than 1 year prior to study entry may
be considered if they received sterilizing therapy to the CNS (resection or
radiation) and have been CNS recurrence-free for a full 1-year period

- History of grade 4 allergic reactions to platinums:

Patients with allergic reaction to platinums (up to and including grade 3 without a
reaction protocol, and up to and including grade 2 in the face of aggressive
pre-treatment) may be eligible pending review of experience, and PI approval.

Patients who have not been rechallenged after a severe reaction may be eligible on a
case-by-case basis.

- Clinically significant GI bleeding or hemoptysis within 28 days prior to the start of
the study

- Inability to swallow pills

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection (no antibiotics prior to entering the study within 7 days), symptomatic
congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or
psychiatric illness/social situations that would limit compliance with study
requirements.

- Pregnant and breast-feeding women: If a woman becomes pregnant or suspects she is
pregnant while participating in this study, she should inform her treating physician
immediately.

- HIV-positive patients on combination antiretroviral therapy are ineligible because of
the potential for pharmacokinetic interactions with AZD2281. In addition, these
patients are at increased risk of lethal infections when treated with
marrow-suppressive therapy such as carboplatin. HIV- positive patients who are not on
combination antiretroviral therapy but with CD4 counts > 500, eligibility is a PI
decision on an individual patient basis.

- Major surgery within the past 28 days
