EF5 in Detecting Oxygen Level and Blood Vessels in Tumor Cells of Patients Undergoing Photodynamic Therapy for Intraperitoneal or Pleural Cancer

The Detection of Tumor Hypoxia and Vascularity in Patients Undergoing Intraperitoneal Photodynamic Therapy

This phase II trial is studying how well EF5 works in detecting oxygen level and blood vessels in tumor cells of patients who are undergoing photodynamic therapy for intraperitoneal or pleural cancer. Diagnostic procedures using EF5 to detect oxygen level and blood vessels in tumor cells may help to improve the way photodynamic therapy is given

Study Overview

• Status: Terminated
• Conditions: Primary Peritoneal Cavity Cancer; Malignant Ascites; Recurrent Malignant Mesothelioma; Advanced Malignant Mesothelioma; Localized Malignant Mesothelioma
• Intervention / Treatment: Other: laboratory biomarker analysis; Procedure: therapeutic conventional surgery; Drug: etanidazole

Detailed Description

OBJECTIVES:

I. Determine the level of hypoxia through etanidazole derivative EF5 binding in patients with intraperitoneal or pleural malignancies treated with photodynamic therapy.

II. Determine the microvascular density in this patient population. III. Determine the relationships between levels of hypoxia, measures of microvascular density, and photosensitizer levels in this patient population.

IV. Correlate hypoxia and photosensitizer levels with clinical outcome in this patient population.

V. Determine the toxic effects of EF5 in this patient population.

OUTLINE: This is a multicenter study.

Patients receive etanidazole derivative EF5 IV over 1-2 hours. Approximately 48 hours after EF5 administration, patients with intraperitoneal tumors undergo surgical resection. Patients with pleural tumors undergo surgical resection approximately 24 hours after EF5 administration. Tumors are then analyzed for EF5 binding and microvascular density by immunohistochemistry and fluorescent antibody techniques.

Patients are followed at 2 weeks and at 30-45 days post EF5 infusion.

PROJECTED ACCRUAL: A total of 80 patients (50 with intraperitoneal malignancy and 30 with pleural malignancy) will be accrued for this study within 2.5 years. Patients are stratified by disease (intraperitoneal malignancy vs pleural malignancy).

Intervention / Treatment

Experimental: Diagnostic (etanidazole); Patients receive etanidazole derivative EF5 IV over 1-2 hours. Approximately 48 hours after EF5 administration, patients with intraperitoneal tumors undergo surgical resection. Patients with pleural tumors undergo surgical resection approximately 24 hours after EF5 administration. Tumors are then analyzed for EF5 binding and microvascular density by immunohistochemistry and fluorescent antibody techniques.

Other: laboratory biomarker analysis; Correlative studies; Procedure: therapeutic conventional surgery; Undergo surgery; Drug: etanidazole; Given IV; Other Names: 2-nitro-imidazole derivative; SR-2508

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Level of hypoxia in tumor nodules	Exploratory techniques will be used to describe patterns of EF5 binding as well as MVD within and among patients.	At the completion of surgery
Inter- and intra-patient variability of hypoxia by EF5 binding	Inter- and intra-subject variability can be estimated using summary statistics (standard deviations, or the range of data).	At the completion of surgery
Levels of microvascular density by PECAM/CD31 staining	Distributions of the four EF5 binding variables and MVD will be examined graphically we anticipate that certain variables may have a Poisson distribution.	At the completion of surgery
Relationships among levels of hypoxia, microvascular density, and photosensitizer levels		At the completion of surgery
Associations between hypoxia and photosensitizer levels in tumor nodules with clinical outcome periodically until disease recurrence		Not Provided

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Toxicity of EF5 administration	All observed toxicities will be graded, tabled for each stratum (IP study) and for the entire study and summarized by frequencies and percentages.	Up to 45 days after EF5 infusion
