10-Propargyl-10-Deazaaminopterin Plus Probenecid in Treating Patients With Advanced Solid Tumors

Basic Trial Information

Objectives

1. Determine the maximum tolerated dose of 10-propargyl-10-deazaaminopterin and probenecid in patients with advanced solid tumors.
2. Determine the therapeutic activity of this regimen in these patients.
3. Determine the toxic effects of this regimen in these patients.
4. Determine the pharmacokinetics of this regimen in these patients.

Expected Enrollment

A total of 35-40 patients will be accrued for this study.

Outline

This is a dose-escalation study of 10-propargyl-10-deazaaminopterin (PDX) and probenecid.

Patients receive probenecid IV and PDX IV on day 1. Treatment repeats every 2 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive sequentially escalating doses of probenecid and PDX until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 of 6 patients experience dose-limiting toxicity.
