Study Description

Brief Summary: Diagnostic procedures using the drug EF5 to detect the presence of oxygen in tumor cells may help to plan effective treatment for solid tumors. This phase I trial is studying how well EF5 works in detecting the presence of oxygen in tumor cells in patients with solid tumors that can be biopsied or removed by surgery

Detailed Description: PRIMARY OBJECTIVES: I. Determine the optimal dose of etanidazole derivative EF5 that is safely tolerated and provides optimal signal-to-noise ratio in patients with solid tumors. II. Determine the toxic effects of EF5 in this patient population. III. Determine the pharmacokinetics of EF5 in this patient population. IV. Determine the dose of EF5 that provides a mean signal-to-noise ratio (maximum binding in anoxia to minimum binding) of 75. V. Determine the relationship between tumor oxygenation by EF5 binding and needle electrode measurements. VI. Compare the levels of EF5 binding in regions of low and high blood flow. OUTLINE: This is a dose-escalation study. Patients receive etanidazole derivative EF5 IV over 1-2 hours beginning approximately 24 hours prior to surgery. Tumors are then resected or biopsied after Eppendorf needle electrode measurements. Cohorts of 6 patients receive escalating doses of EF5 until the maximum tolerated dose (MTD) or optimal dose is determined. The MTD is defined as the dose preceding that at which 2 or more patients experience dose-limiting toxicity. The optimal dose is defined as the dose level at or below the MTD and results in a signal-to-noise ratio of 75 or greater. Thirty additional patients are treated at the optimal dose. Patients are followed at 30-45 days post EF5 infusion. PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.
