excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained
up to 4 weeks (28 days) prior to initiation of treatment on Day 1. Subjects from whom
newly-obtained samples cannot be provided (e.g. inaccessible or subject safety
concern) may submit an archived specimen only upon agreement from the Principal
Investigator.
6. Have a performance status of 0 or 1 on the ECOG Performance Scale.
7. Demonstrate adequate organ function, all screening labs should be performed within 14
days of treatment initiation. Hematological: Absolute neutrophil count (ANC) >/= 1,500
/mcL; Platelets >/= 100,000 / mcL; Hemoglobin >/= 9 g/dL or >/= 5.6 mmol/L without
transfusion or EPO dependency (within 7 days of assessment). Renal: Serum creatinine
</= 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance
>/= 60mL/min for subjects with creatinine levels > 1.5 X ULN. Hepatic: Serum total
bilirubin </= 1.5 X ULN or direct bilirubin </= ULN for subjects with total bilirubin
levels > 1.5 ULN; AST (SGOT) and ALT (SGPT) 9 </= 2.5 X ULN OR </= 5 X ULN for
subjects with liver metastases.
8. contd from #7. Albumin >/= 2.5 g/dL. Coagulation: International Normalized Ratio (INR)
or Prothrombin Time (PT) Activated Partial Thromboplastin Time (aPTT) </=1.5 X ULN
unless subject is receiving anticoagulant therapy as long as PT or PTT is within
therapeutic range of intended use of anticoagulants </= 1.5 X ULN unless subject is
receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of
intended use of anticoagulants
9. Female subject of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to receiving the first dose of study medication. If
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required.
10. Female subjects of childbearing potential should be willing to use 2 methods of birth
control or be surgically sterile, or abstain from heterosexual activity for the course
of the study through 120 days after the last dose of study medication. Subjects of
childbearing potential are those who have not been surgically sterilized or have not
been free from menses for > 1 year.
11. Male subjects should agree to use an adequate method of contraception starting with
the first dose of study therapy through 120 days after the last dose of study therapy.
Exclusion Criteria:

of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment.
2. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment.
3. Has a known history of active TB (Bacillus Tuberculosis)
4. Hypersensitivity to pembrolizumab, azacitidine, mannitol, or any of their excipients.
5. Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study
Day 1 or who has not recovered (i.e., </= Grade 1 or at baseline) from adverse events
due to agents administered more than 4 weeks earlier.
6. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy
within 2 weeks prior to study Day 1 or who has not recovered (i.e., </= Grade 1 or at
baseline) from adverse events due to a previously administered agent. - Note: Subjects
with = Grade 2 neuropathy are an exception to this criterion and may qualify for the
study. - Note: If subject received major surgery, they must have recovered adequately
from the toxicity and/or complications from the intervention prior to starting
therapy.
7. Has a known additional malignancy that is progressing or requires active treatment.
Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the
skin that has undergone potentially curative therapy or in situ cervical cancer.
8. Has known active central nervous system (CNS) metastases and/or carcinomatous
meningitis. Subjects with previously treated brain metastases may participate provided
they are stable (without evidence of progression by imaging for at least four weeks
prior to the first dose of trial treatment and any neurologic symptoms have returned
to baseline), have no evidence of new or enlarging brain metastases, and are not using
steroids for at least 7 days prior to trial treatment. This exception does not include
carcinomatous meningitis, which is excluded regardless of clinical stability.
9. Has 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 (eg., thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.
10. Has known history of, or any evidence of active, non-infectious pneumonitis.

16. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent [for Arm
A only].
