This is a single arm two-stage phase II study with crizotinib (Xalkori®) in the treatment of subjects with metastatic urothelial cancer of the bladder, upper (ureter or renal pelvis) or lower (urethra) urinary tracts. The purpose of this study is to see if this experimental drug has a potential benefit in subjects with stage 4 urothelial cancer. This study tests crizotinib used alone in subjects with urothelial cancer, previously treated with chemotherapy, and whose tumors have certain proteins. Proteins are complex natural substances essential to the structure and function of all living cells. These proteins, c-MET or RON, may trigger molecular pathways that are involved in the growth and spread of bladder or upper urinary tract cancer. Crizotinib is a drug taken by mouth that blocks these pathways. Early laboratory research suggests that crizotinib may benefit patients with urothelial and other cancers with these molecular pathways.
This is a single arm two-stage phase II study designed to evaluate the objective response
rate in subjects with metastatic urothelial cancer demonstrating c-MET or RON overexpression
who have received prior therapy with a cisplatin or carboplatin containing regimen.
Subjects will be recruited at Levine Cancer Institute (LCI) and other participating sites.
Immunohistochemistry will be utilized to define tumor sample c-MET and RON protein expression
patterns for assignment into molecular cohorts as described in section 12.1.
In the first stage of this study, subjects will be enrolled in parallel to three molecularly
defined cohorts as follows:
1. c-MET high (>50%), RON null (0-9%) (n = 14 subjects)
2. c-MET-positive (10-100%), RON-positive (10-100%) (n = 7 subjects)
3. c-MET null (0-9%), RON-positive (10-100%) (n = 7 subjects)
All enrolled subjects will continue with study treatment until criteria for treatment
discontinuation has been met.
If Stage 1 response criteria are met in a cohort, the cohort may be considered for expansion,
and additional subjects (16 in Cohort 1 or 25 in Cohorts 2 or 3) may then be enrolled into
that cohort in Stage 2. An expansion cohort will be defined by the Sponsor- Investigator
following review of all available trial data which will be conducted after the first Stage 1
cohort has completed accrual and at least every six months thereafter until all Stage 1
cohorts have completed accrual.
If more than one cohort meets Stage 1 response criteria (2 responses out of 14 subjects for
Cohort 1 or 1 response out of 7 subjects for each of Cohorts 2 and 3), then the cohort
showing the highest response rate will be given highest consideration for expansion.

Primary Outcome 1 - Measure: Overall response rate
Primary Outcome 1 - Time Frame: Through study completion, an average of 1 year.
Subjects must meet all of the following criteria:
1. Histologically confirmed stage IV urothelial carcinoma of the bladder, upper urinary
tract or urethra.
2. Prior treatment for metastatic disease with at least one cisplatin or
carboplatin-based multi-agent chemotherapeutic regimen. Prior immunotherapy with
anti-PD-L1 or anti-PD1 agents is allowed.
o Chemotherapy received peri-operatively for non-metastatic bladder cancer will be
considered a prior regimen if less than 24 months have elapsed since treatment.
3. Measurable disease per RECIST 1.1. See Section 10 for the evaluation of measurable
4. Tissue Pre-screen: Archived tissue must have been obtained within 60 months of subject
signing tissue pre-screen consent. Biopsy accessible disease if adequate archival
tissue does not exist for molecular characterization.
Treatment: Available tumor specimen C-MET/RON expression results that meet the
criteria for one of the three molecularly defined cohorts per Section 4.2
5. Age ≥ 18 years
6. ECOG performance status ≤ 2
7. Adequate liver function: AST and ALT ≤ 2x upper limit of normal, bilirubin ≤ 1.5x
upper limit of normal
8. Adequate bone marrow function: Platelets ≥ 100,000 cells/mm3, hemoglobin > 8.0 g/dL
and ANC ≥ 1,500 cells/mm3
9. Adequate renal function with a creatinine clearance (based on Cockgroft-Gault formula)
≥ 45 mL/min
10. Ability to understand and the willingness to sign a written informed consent document
11. Able to swallow oral medication
Subjects must not meet any of the following criteria
1. Currently receiving any other investigational agents, a prior c-MET inhibitor, or
2. Pregnant or breast feeding, because crizotinib can cause fetal harm
3. Uncontrolled and current illness including, but no limited to:
- Ongoing or active infection
- Symptomatic congestive heart failure
- Unstable angina pectoris
- Cardiac arrhythmia, or
- Psychiatric illness/social situations that would limit compliance with study
4. Presence of any of the following within the previous 3 months of treatment consent:
- Myocardial infarction
- Severe/unstable angina
- Coronary/peripheral artery bypass graft
- Congestive heart failure, or
- Cerebrovascular accident including transient ischemia attack

Sleep apnea considered to be a sleep disorder (and not a pulmonary disorder) by the
investigator will be allowed.
8. Subjects receiving any medications or substances that are strong inhibitors or
inducers of CYP3A are ineligible. Because the lists of these agents are constantly
changing, it is important to regularly consult a frequently updated list such as
http://medicine.iupui.edu/clinpharm/ddis/table/aspx; medical reference texts such as
the Physicians' Desk Reference may also provide this information. As part of the
enrollment/informed consent procedures, the subject will be counseled on the risk of
interactions with other agents, and what to do if new medications need to be
prescribed or if the subject is considering a new over-the-counter medicine or herbal
