| Eligibility |
Inclusion Criteria:
- Be willing and able to provide written informed consent for the trial.
- Over 18 years of age on day of signing informed consent.
- ECOG PS = 2; please see protocol for specific details regarding ECOG PS for each
cohort.
- Have histologically confirmed muscle invasive disease of the urinary bladder. For
subjects who have tumors limited to the upper tract including renal pelvis or ureters,
muscle invasive disease does not need to be pathologically proven, and a CT urogram
must be performed (MRI is not acceptable to meet this criterion). To be eligible,
subjects with upper tract tumors of the renal pelvis and ureter(s) must meet a high
risk assessment defined as: tumor = 1cm and/or hydronephrosis and/or high grade
pathology and/or multifocal disease, where a radical NU approach to treat localized
disease is warranted.
- Histology must be urothelial carcinoma (transitional cell carcinoma) or urothelial
carcinoma with mixed histology/features.
- Clinical stage cT2-4aN0M0. Please see exclusion criteria for acceptable N0
determination/lymph node size.
- Have a surgical evaluation that documents the plan for multimodality therapy with a
consolidative radical cystectomy or nephroureterectomy.
NOTE on surgical intent: Criteria for acceptable surgical risk are not defined and per
treating urologist. Minimum guidance on surgical intent includes subjects who do not have
significant cardiovascular disease such as NHYA class III or IV heart failure, unstable
arrhythmias or angina, active CAD, and/or EF<25%. Specific diagnostic testing to determine
surgical intent is not required and per treating urologist or oncologist discretion.
- Having an archived tumor block available to submit 11 unstained slides for PD-L1
expression, basal and luminal subtype analysis is MANDATORY for subjects with bladder
cancer (optional for those with tumors limited to the upper tract if sufficient tissue
is not available). If slides are not available, a biopsy is strongly encouraged to
obtain tissue for submission (See Study Procedures Manual for collection, labeling and
shipping instructions).
- Subjects on full dose anticoagulants must be on a stable regimen of warfarin or low
molecular weight heparin (LMWH) for at least two weeks.
- Demonstrate adequate organ function as defined below: All screening labs should be
performed within 28 days of study registration.

unless subject is receiving anticoagulant therapy as long as PT or PTT is
within therapeutic range of intended use of anticoagulants

receiving anticoagulant therapy and as long as PT or PTT is within
therapeutic range of intended use of anticoagulants
- Female subjects of childbearing potential must have a negative urine or serum
pregnancy test within 72 hours prior to study registration. If the urine test is
positive or cannot be confirmed as negative, a serum pregnancy test is required.
- Female subjects of childbearing potential must be willing to use 2 methods of birth
control, be surgically sterile, or abstain from heterosexual intercourse for the
course of the study and through 120 days after the last dose of study medication.
NOTE: Subjects of childbearing potential are those who have not been surgically
sterilized or have not been free from menses for > 1 year.
- Male subjects must agree to use a barrier method of male contraception starting with
the first dose of study therapy and through 120 days after the last dose of study
therapy.
COHORT I - CISPLATIN-ELIGIBLE:
In addition to the inclusion criteria listed above, Cohort I subjects must satisfy all of
the following criteria:
- Glomerular filtration rate (GFR) or creatinine clearance (Ccr) = 50 mL/min. (24 hour
urine preferred). The cisplatin dose will be split over two days for values between
50-59 mL/min
- ECOG PS 0, 1 (and not 2)
- Hearing impaired = grade 1 (may or may not be enrolled in a monitoring program)
- Peripheral neuropathy =grade 1
COHORT II - CISPLATIN-INELIGIBLE:
In addition to the inclusion criteria listed above, Cohort II subjects must also meet any
ONE of the following criteria:
- GFR or Ccr: 30-49 (24 hour urine preferred).
- ECOG PS 2
- Hearing impaired =grade 2 as assessed by treating physician (may or may not be
enrolled in a monitoring program).
- Peripheral neuropathy of Grade 2-4
Exclusion Criteria:
Subjects may not have any of the following:
- A non-surgical approach recommended by the treating urologist due to any reason.
Criteria for surgical intent are not defined and, rather, suitability is determined
and documented by the subject's treating urologist. Minimum guidance on surgical
intent includes subjects who do not have significant cardiovascular disease such as
NHYA class III or IV heart failure, unstable arrhythmias or angina, active CAD, and/or
EF<25%. Specific cardiopulmonary diagnostic testing to determine surgical intent is
not required and per treating urologist or oncologist discretion.
- Has abdomino-pelvic short axis lymph node of =15mm without biopsy. NOTE: A subject
with a staging biopsy proving a non-neoplastic process/N0 will meet inclusion.
- Subjects with disease that is limited to the upper tract urothelial cancer and is
considered low risk defined as: unifocal disease and tumor size <1cm, and low grade
cytology, and without an invasive aspect on CT-urography.
- Is currently participating in or has participated in a study of an investigational
agent or using an investigational device within 28 days prior to study registration.
- Has a diagnosis of immunodeficiency or received systemic steroid therapy or any other
form of immunosuppressive therapy within 7 days prior to study registration. Subjects
on steroids for physiologic replacement due to a non-cancer related cause would not be
excluded.

meningitis. Brain imaging is not required and per discretion of treating physician.
- Has an active autoimmune disease requiring systemic treatment within the past 3 months
or a documented history of clinically severe autoimmune disease, or a syndrome that
requires systemic steroids or immunosuppressive agents. NOTE: Subjects with vitiligo
or resolved childhood asthma/atopy would be an exception. Subjects that require
intermittent use of bronchodilators or local steroid injections would not be excluded
from the study. Subjects with hypothyroidism stable on hormone replacement or
Sjogren's syndrome will not be excluded from the study.
- Has known evidence of interstitial lung disease or active, non-infectious pneumonitis.
- Has an active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality

through 120 days after the last dose of trial treatment.
- Has received therapy with hematopoietic growth factor such as G-CSF or GM-CSF in the
