TNF-Bound Colloidal Gold in Treating Patients With Advanced Solid Tumors

Phase 1
Completed
Conditions
Unspecified Adult Solid Tumor, Protocol Specific
Registration Number
NCT00356980
Lead Sponsor
National Institutes of Health Clinical Center (CC)
Brief Summary

RATIONALE: Biological therapies, such as TNF-bound colloidal gold, may stimulate the immune system in different ways and stop tumor cells from growing.

PURPOSE: This phase I trial is studying the side effects and best dose of TNF-bound colloidal gold in treating patients with advanced solid tumors.

Detailed Description

OBJECTIVES:

Primary

* Determine the maximum tolerated dose of TNF-bound colloidal gold (CYT-6091) in patients with advanced solid tumors.

* Determine the toxicities of CYT-6091 in these patients.

Secondary

* Determine the pharmacokinetics of CYT-6091 in these patients.

* Evaluate biopsy samples of tumor and adjoining normal tissue for levels of CYT-6091.

* Determine if antitumor effects of CYT-6091 occur in these patients.

OUTLINE: This is an open-label, sequential cohort, dose-escalation study.

Patients receive TNF-bound colloidal gold (CYT-6091) IV on days 1 and 15 (course 1). Approximately 4-6 weeks later, patients are re-staged and responding patients may receive another course of therapy. Patients may receive up to 3 re-treatment courses.

Cohorts of 3-6 patients receive escalating doses of CYT-6091 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 6 patients experience dose-limiting toxicity.

Blood samples are collected at baseline and periodically during the first course of therapy for pharmacokinetic and pharmacodynamic analyses.

After completion of study treatment, patients are followed every 3 months for 1 year, every 4 months for the next year, and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
