subject is receiving anticoagulant therapy as long as PT or partial thromboplastin
time (PTT) is within therapeutic range of intended use of anticoagulants (within 28
days of cycle 1 day 1)
- Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless participant is
receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of
intended use of anticoagulants (within 28 days of cycle 1 day 1)
- 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
- Female subjects of childbearing potential must be willing to use an adequate method of
contraception; contraception, for the course of the study until at least 12 months
after the last dose of study medication
**Note: Abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the subject
- Male subjects of childbearing potential must agree to use an adequate method of
contraception starting with the first dose of study therapy until at least 12 months
after the last dose of study therapy
- Note: Abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the subject
Exclusion Criteria:

of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment
- 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, except for physiologic corticosteroid replacement therapy for adrenal or
pituitary insufficiency which is permitted
- Has a known history of active TB (Bacillus tuberculosis)
- Hypersensitivity to pembrolizumab or any of its excipients
- 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
- Prior allogeneic transplant, within the last 5 years
- 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
- 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
- Has known active central nervous system (CNS) metastases and/or lymphomatous
meningitis; subjects with previously treated brain metastases or lymphomatous
meningitis 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
- Has active autoimmune disease that has required systemic treatment in the past 2 years

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

pneumonitis/interstitial lung disease
- Has an active infection requiring systemic therapy
- Has a history or current evidence of any condition, therapy, or laboratory abnormality

the subject to participate, in the opinion of the treating investigator
- Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial

vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist)
