Trial Information

Identification of Genetic Determinants of Response to Neoadjuvant Cisplatin-based Chemotherapy in Urothelial Cancer

In this trial patients will submit germline (blood) and tumor tissue samples as part of two
existing sample collection protocols for analysis of genetic and molecular markers governing
response to chemotherapy. Pathologic review of tissue samples after neoadjuvant therapy will
allow determination of the complete response rate (pT0 rate) and this will be compared
between patients with "susceptible" and "resistant" genetic/molecular cisplatin
susceptibility variants.

Primary Endpoint: Analysis of whether a small set of previously‐identified germline
"cisplatin susceptibility" polymorphisms associate with achievement of a complete pathologic
response to neoadjuvant cisplatin‐based chemotherapy in urothelial cancer patients.

Secondary Endpoints: To perform companion genetic or molecular analyses of other
previously‐identified gene, SNP, or microRNA "cisplatin susceptibility" candidates in these
patients, using tumor and/or germline tissue.

Exploratory Endpoints: To perform unbiased, hypothesis‐generating SNP, gene, or microRNA
array studies to identify novel germline or tumor determinants which may predict response to
cisplatin‐based chemotherapy.

Inclusion Criteria:

- Patients with clinical T2 through T4 urothelial carcinoma of the bladder or upper

- Patients must be deemed appropriate by the treating physician to require
cisplatin-based neoadjuvant chemotherapy for urothelial cancer. Consideration of
regional nodal status as part of the decision for appropriateness for neoadjuvant
chemotherapy will be left to the treating physician.

- Patients must be scheduled to proceed to definitive urothelial cancer surgery,
including either cystectomy or nephrectomy/ureterectomy, after chemotherapy.

- Age >18 years.

Exclusion Criteria:

- Patients receiving cisplatin‐based chemotherapy for urothelial cancer in the adjuvant
setting or for metastatic disease.
