3-AP in Treating Patients With Advanced or Metastatic Solid Tumors

Phase 1
Completed
Conditions
Unspecified Adult Solid Tumor, Protocol Specific
Interventions
Other: pharmacological study
Procedure: laboratory biomarker analysis
Registration Number
NCT00390052
Lead Sponsor
National Cancer Institute (NCI)
Brief Summary

This phase I trial is studying the side effects and best dose of 3-AP in treating patients with advanced or metastatic solid tumors. 3-AP may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description

OBJECTIVES:

I. Determine the safety, tolerability, and toxicity of oral 3-AP in patients with advanced solid tumors.

II. Determine the maximum tolerated dose and recommended phase II dose of this drug in these patients.

III. Determine the oral bioavailability and pharmacokinetics of this drug. IV. Assess tumoral expression of genes involved in response and resistance to 3-AP.

V. Observe and record any tumor response in these patients.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive a one time dose of 3-AP IV over 2 hours on day -7. Patients then receive oral 3-AP twice daily on days 1-3, 8-10, and 15-17. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of oral 3-AP 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 samples for pharmacokinetic analysis are collected periodically over 8 hours after the IV dose of 3-AP and after the first oral dose of 3-AP during course 1.

After completion of study treatment, patients are followed periodically.

Arm ItriapinePatients will receive a 2-hour infusion of 3-AP once in week 1. Beginning in week 2, they will receive 3-AP by mouth twice a day 3 days a week for 3 weeks. Treatment with 3-AP by mouth may repeat every 4 weeks for as long as benefit is shown.

Primary Outcome Measures
NameTimeMethod
Maximum tolerated dose of oral 3-AP determined by dose-limiting toxicities graded according to the NCI CTCAE version 3.028 days
Secondary Outcome Measures
NameTimeMethod
Serum pharmacokinetics of oral triapineBaseline, day 4, and day 8

Summary statistics of the pharmacokinetic parameters will be tabulated using the logarithmic scale where appropriate. The relationship of the AUC to the dose will be assessed by least-square regression analysis.
