This phase II trial studies the side effects of pembrolizumab and to see how well it works in treating participants with bladder cancer who are undergoing surgery to remove the bladder. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread in participants with bladder cancer.
I. To characterize the safety profile of pembrolizumab in patients with urothelial carcinoma
undergoing radical cystectomy.
I. To explore a signal of anti-cancer immunological activity by evaluating surgical specimens
for evidence of post-treatment lymphocytic infiltration and residual tumor compared to
pre-treatment biopsy samples.
II. To explore a signal of biomarker activity by evaluating surgical specimens and blood
samples for established and not-so-established markers of response to pembrolizumab.
III. To report the tumor yield and sufficiency of tumor for immunological and biomarker
Participants receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Courses
repeat every 3 weeks for up to 2 courses in the absence of disease progression or
unacceptable toxicity. About 4 weeks after treatment, participants then undergo radical
cystectomy per standard of care.
After completion of study treatment, participants are followed up every 4 weeks for up to 24

- Have absence of metastatic disease as determined by conventional imaging studies and
be considered a good surgical candidate by the treating physician.

- Creatinine OR calculated creatinine clearance =< 1.5 x upper limit of normal (ULN) OR
>= 60 mL/min for subject with creatinine levels > 1.5 x institutional ULN. Creatinine
clearance should be calculated per institutional standard.
- Total bilirubin =< 1.5 x ULN OR direct bilirubin =< ULN for subjects with total

ULN OR =< 5 x ULN for subjects with liver metastases.
- Albumin > 2.5 mg/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
- 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 for the course of the study through 120 days 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 through 120 days after
the last dose of study therapy. Note: Abstinence is acceptable if this is the usual
lifestyle and preferred contraception for the subject.
- Is currently participating and receiving pembrolizumab or has participated in a study
of an investigational agent and received pembrolizumab or used an investigational
device within 4 weeks of the first dose of study 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 study
- Has a known history of active TB (Bacillus tuberculosis).
- Has a known history of hypersensitivity to pembrolizumab or any of its excipients.
- Has had prior systemic anti-cancer therapy for the treatment of bladder cancer. Prior
intravesical therapies, whether Bacillus Calmette-Guerin (BCG) (including but not
limited to: persistent high-grade disease or recurrence within 6 months of receiving
at least two courses of intravesical BCG [at least five of six induction doses and at
least two of three maintenance doses]; or T1 high-grade disease at the first
evaluation following induction BCG alone [at least five of six induction doses]),
chemotherapy or otherwise, will remain eligible.
- Has any other malignancy diagnosed within 2 years of screening with the exception of
basal or squamous cell skin cancer, or non-invasive cancer of the cervix, or any other
cancer deemed by the treating physician to be of low-risk for progression or patient
morbidity during the study period.
- Has known metastatic disease as determined by conventional staging studies.
- 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 (e.g., thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.
- Has known history of, or any evidence of active, non-infectious pneumonitis.
- Has a clinically significant active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating physician.
- Is pregnant or breastfeeding, or expecting to conceive or father children within the

through 120 days after the last dose\ of trial treatment.
