PR-104 in Treating Patients With Advanced Solid Tumors

Phase 1
Completed
Conditions
Unspecified Adult Solid Tumor, Protocol Specific
Interventions
Other: laboratory biomarker analysis
Other: pharmacological study
Registration Number
NCT00349167
Lead Sponsor
Proacta, Incorporated
Brief Summary

RATIONALE: Drugs used in chemotherapy, such as PR-104, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase I trial is studying the side effects and best dose of PR-104 in treating patients with advanced solid tumors.

Detailed Description

OBJECTIVES:

Primary

* Evaluate the safety and tolerability of PR-104 in patients with advanced solid tumors.

* Determine the maximum tolerated dose of PR-104 in these patients.

Secondary

* Characterize the pharmacokinetics of PR-104 and its alcohol metabolite in these patients.

* Assess evidence of antitumor activity of this drug in these patients.

Tertiary

* Examine metabolic changes in tumors of these patients using fludeoxyglucose F 18 positron emission tomography scanning.

OUTLINE: This is a multicenter, open-label, prospective, uncontrolled, dose-escalation study.

Patients receive PR-104 IV over 60 minutes on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of PR-104 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Blood is collected at baseline and then periodically during study treatment for pharmacokinetic and tumor marker studies. Patients undergo fludeoxyglucose F 18 positron emission tomography scanning before beginning study treatment and after completion of course 2 to assess metabolic activity of the tumor.

After completion of study treatment, patients are followed at 30 days.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
