Inclusion Criteria:

Endometrioid adenocarcinoma, serous adenocarcinoma, undifferentiated carcinoma,
dedifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma,
adenocarcinoma not otherwise specified (N.O.S.), mucinous adenocarcinoma, squamous
cell carcinoma, and transitional cell carcinoma) or endometrial carcinosarcoma).
Histologic documentation of diagnosis of carcinoma is required. MSI-high patients will
be identified based on immunohistochemistry or MSI testing of archival tumor specimens
by department of pathology or via known mutations found in mismatch repair genes via
the Integrated Mutation Profiling of Actionable Cancer Targets (IMPACT) assay through
MSKCC IRB# 12-245.
- All patients must have measurable disease. Measurable disease is defined by RECIST
(version 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.
- Patients must have at least one "target lesion" to be used to assess response on this
protocol as defined by RECIST version 1.1. Tumors within a previously irradiated field
will be designated as "non-target" lesions unless progression is documented or a
biopsy is obtained to confirm persistence at least 90 days following completion of
radiation therapy.

- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Resolution of (non-laboratory) adverse effects of recent surgery, radiotherapy, or
chemotherapy to Grade =1 prior to first study treatment (with the exception of
alopecia or neuropathy).
- Patients must have had one prior platinum-based chemotherapeutic regimen for
management of endometrial carcinoma or carcinosarcoma. Initial treatment may include
chemotherapy, chemotherapy and radiation therapy, and/or consolidation/maintenance
therapy. Chemotherapy administered in conjunction with primary radiation as a
radio-sensitizer WILL be counted as a systemic chemotherapy regimen.
- Patients are allowed to receive, but are not required to receive, three additional
cytotoxic regimen for management of recurrent or persistent disease. Hormonal
therapies will not count toward the prior regimen limit.
- Adequate normal organ and marrow function defined by the following laboratory results
obtained within 14 days prior to first treatment:
- Absolute neutrophil count (ANC) = 1.5 x 10^9/L (> 1500 per mm^3)
- Platelet = 100 x 10^9/L (>100,000 per mm^3)
- Hemoglobin = 9.0 g/dL
- Serum bilirubin = 1.5 x institutional upper limit of normal (ULN). (Unless
Gilbert's Syndrome,for which Bilirubin = 3 x institutional upper limit of normal
(ULN) without concurrent clinically significant liver disease)
- AST (SGOT)/ALT (SGPT) = 3 x institutional upper limit of normal unless (ULN)
unless liver metastases are present, in which case it must be = 5x ULN
- Serum creatinine = 1.5 x institutional upper limit of normal (ULN)
- Female subjects must either be of non-reproductive potential (ie, post-menopausal by
history: =55 years old and no menses for =1 year without an alternative medical cause;
OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of
bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.
- Subject is willing and able to comply with the protocol for the duration of the study
including undergoing treatment and scheduled visits and examinations including follow
up.
- Patients must have been enrolled, or agree to consent to the companion genomic
profiling study MSKCC IRB# 12-245. Results must be available before starting treatment
on protocol.
- Patients must have signed an approved informed consent and authorization permitting
release of personal information.
Exclusion Criteria:
- Involvement in the planning and/or conduct of the study (applies to both AstraZeneca
staff and/or staff at the study site); Previous enrollment in the present study.
- Participation in another clinical study with receipt of an investigational product
during the last 4 weeks
- Any previous treatment with a PD-1 or PD-L1 inhibitor, including durvalumab or any
anti-CTLA4, including tremelimumab.
- History of another primary malignancy except for:
- Malignancy treated with curative intent and with no known active disease =3 years
before the first dose of study drug and of low potential risk for recurrence
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence
of disease
- Adequately treated carcinoma in situ without evidence of disease (eg, cervical
cancer in situ)
- Adequately treated stage 1 breast cancer.
- Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, targeted
therapy, biologic therapy, tumor embolization, monoclonal antibodies) < 21 days prior
to the first dose of study drug. Receipt of the last dose of hormonal therapy within <
7 days prior to the first dose of study drug.
- Any prior radiation therapy must be discontinued at least four weeks prior to
registration.
- At least 4 weeks must have elapsed since the patient underwent any major surgery
(e.g., major: laparotomy, laparoscopy) There is no delay in treatment for minor
procedures (e.g., central venous access catheter placement).
- Mean QT interval corrected for heart rate (QTc) =470 ms calculated from 3
electrocardiograms (ECGs)
- Current or prior use of immunosuppressive medication within 28 days before the first
dose of durvalumab or durvalumab and tremelimumab, with the exceptions of intranasal
and inhaled corticosteroids or systemic corticosteroids at physiological doses, which
are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Patients
who have received acute, low dose, systemic immunosuppressant medications (e.g.,
dexamethasone for nausea or steroids as CT scan contrast premedication) may be
enrolled.
- Any prior Grade =3 immune-related adverse event (irAE) while receiving any previous
immunotherapy agent, or any unresolved irAE > Grade 1
- Active or prior documented autoimmune disease within the past 2 years NOTE: Subjects
with vitiligo, Grave's disease, or psoriasis not requiring systemic treatment (within

angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, active
bleeding diatheses including any subject known to have evidence of acute or chronic
hepatitis B, hepatitis C or human immunodeficiency virus (HIV), or psychiatric
illness/social situations that would limit compliance with study requirements or
compromise the ability of the subject to give written informed consent

- History of leptomeningeal carcinomatosis
- Receipt of live attenuated vaccination within 30 days prior to study entry or within
30 days of receiving durvalumab or tremelimumab.
