| Eligibility |
Inclusion Criteria:
- Patients must have platinum-sensitive, recurrent high-grade serous or high-grade
endometrioid (grade 3) ovarian, primary peritoneal, or fallopian tube cancer. Patients
with other histologies are also eligible, provided that the patient has a known
deleterious germline or somatic BRCA1 or BRCA2 mutation identified through testing at
a clinical laboratory. Submission of BRCA testing results (germline and/or somatic) is
required for all patients.
- Platinum-sensitive disease defined as no clinical or radiographic evidence of disease
recurrence for > 6 months (or 182 days) after last receipt of platinum-based therapy.
The date should be calculated from the last administered dose of platinum therapy.
- Patients must have had response (complete or partial) to their prior line of platinum
therapy and cannot have had progression through prior platinum-based therapy.
- Patients must have RECIST 1.1 measurable disease. Patients with biochemical recurrence
based on CA125 levels alone are not eligible.
- Prior therapy:
- Prior chemotherapy must have included a first-line platinum-based regimen with or
without consolidation chemotherapy.
- Prior bevacizumab therapy as a component of frontline or recurrent treatment is
permitted.
- Patients may have received an unlimited number of platinum-based therapies in the
recurrent setting.
- Patients may have received up to one non-platinum-based line of therapy in the
recurrent setting. Prior hormonal therapy will not be counted as this
non-platinum-based line.
- Prior treatment with a PARP inhibitor:
- Patients may not have had a prior PARP inhibitor in the recurrent setting.
- Prior use of a PARP inhibitor in the upfront maintenance setting is allowed
for women with a confirmed BRCA1 or BRCA2 germline or somatic mutation.

setting must have received at least one other chemotherapy regimen for
recurrence prior to enrolling on this trial.

- Patients must be able to swallow and retain oral medications and not have
gastrointestinal illnesses that would preclude absorption of olaparib as judged by the
treating physician.
- Evidence of post-menopausal status or negative urinary or serum pregnancy test for
pre-menopausal patients. Women will be considered post-menopausal if they have been
amenorrheic for 12 months without an alternative medical cause. The following
age-specific requirements apply:
- Women < 50 years of age would be considered post-menopausal if they have been
amenorrheic for 12 months or more following cessation of exogenous hormonal
treatments and if they have luteinizing hormone and follicle-stimulating hormone
levels in the post-menopausal range for the institution or underwent surgical
sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
- Women >= 50 years of age would be considered post-menopausal if they have been
amenorrheic for 12 months or more following cessation of all exogenous hormonal
treatments, had radiation-induced menopause with last menses > 1 year ago, had
chemotherapy-induced menopause with last menses > 1 year ago, or underwent
surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or
hysterectomy).
- Administration of study drugs (olaparib, tremelimumab) may have an adverse effect
on pregnancy and poses a risk to the human fetus, including embryo-lethality.
Women of childbearing potential (WOCBP) must agree to use two (2) highly
effective forms of contraception from up to 14 days prior to enrollment (for oral
contraceptives), during treatment, and for 6 months after the last dose of study
medication.
- Life expectancy >= 12 weeks.
- Patients with brain metastases are eligible if follow-up brain imaging after central
nervous system (CNS)-directed therapy shows no evidence of progression. Imaging
studies must have been completed no later than 14 days prior to enrollment. In
addition, patients must have been successfully weaned off steroid support. Patients
should not have received steroids for the treatment of brain metastases within 14 days
prior to enrollment.
- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral
therapy with undetectable viral load within 6 months are eligible for this trial
- The patient or a legally authorized representative must provide study-specific
informed consent prior to study entry and, for patients treated in the United States
(U.S.), authorization permitting release of personal health information.
Exclusion Criteria:
- Active infection requiring antibiotic therapy (except for uncomplicated urinary tract
infections), including tuberculosis.
- Known clinically significant liver disease, including active viral, alcoholic, or
other hepatitis; and cirrhosis. For patients with evidence of chronic hepatitis B
virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy,
if indicated. Patients with a history of hepatitis C virus (HCV) infection must have
been treated and cured. For patients with HCV infection who are currently on
treatment, they are eligible if they have an undetectable HCV viral load.
- Hormonal therapy directed at treatment for the cancer must be discontinued at least 28
days prior to enrollment. Hormone replacement therapy for symptom management is
permitted.

tomography [CT] scan contrast allergy premedication).
- Patients with active autoimmune disease that has required systemic treatment in the
past 2 years (i.e., with use of disease modifying agents, corticosteroids, or
immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or
physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency,
etc.) is not considered a form of systemic treatment.
- Patients with autoimmune disease (e.g., psoriasis, extensive atopic dermatitis,
severe asthma, inflammatory bowel disease [IBD], multiple sclerosis [M.S.],

permitted.
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to olaparib or tremelimumab.

situations that would limit compliance with study requirements, substantially increase
risk of incurring adverse events (AEs) or compromise the ability of the patient to
give written informed consent.
