 I. Measuring tissue intermediate endpoint biomarkers such as EGF-R mutations EGFR vIII, exon 19-21, Ki67, activated Caspase 3, Akt, P-Akt, MAP kinase, P-MAP kinase, COX-2, survivin, and BLCA-4 and we will also determine survivin and BLCA-4 levels in urine specimens as surrogate tumor markers. Biomarkers associated with the EGF-R pathway, including Akt and P-Akt will be studied by immunohistochemistry. Additionally, Ki67, activated Caspase 3 as a marker of apoptosis, and COX-2 will serve as biological endpoint biomarkers to measure the effects of G-2535 on proliferation, apoptosis, and other processes and molecules relevant to bladder cancer. These studies will be performed on tumors as well as adjacent and remote normal urothelium. II. Safety will also be studied.
