Clinical Trial: EF5 in Treating Patients With Solid Tumors
This study is currently recruiting patients.
Purpose
RATIONALE: Diagnostic procedures using the drug EF5 to detect the presence of oxygen in tumor cells may help to plan effective treatment for solid tumors.
PURPOSE: 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.
| Condition | Treatment or Intervention | Phase |
|---|---|---|
| unspecified adult solid tumor, protocol specific | Drug: EF5 Procedure: conventional surgery Procedure: diagnostic test Procedure: fluorescent antibody technique Procedure: surgery | Phase I |

Official Title: Phase I Study of the Etanidazole Derivative EF5 for the Detection of Hypoxia in Patients With Solid Tumors
OBJECTIVES:
- Determine the optimal dose of etanidazole derivative EF5 that is safely tolerated and provides optimal signal-to-noise ratio in patients with solid tumors.
- Determine the toxic effects of EF5 in this patient population.
- Determine the pharmacokinetics of EF5 in this patient population.
- Determine the dose of EF5 that provides a mean signal-to-noise ratio (maximum binding in anoxia to minimum binding) of 75.
- Determine the relationship between tumor oxygenation by EF5 binding and needle electrode measurements.
- 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.
