RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of aminopterin in treating patients who have refractory leukemia.

Condition Intervention Phase
Drug: aminopterin
Drug: leucovorin calcium
Phase 2

Study Type: Interventional

Study Start Date: July 1997
Study Completion Date: September 2007
Detailed Description:

OBJECTIVES: I. Determine the maximum tolerated dose of aminopterin in patients with refractory leukemia and minimal previous exposure to antifolate agents. II. Determine the antileukemic activity of aminopterin in adults and children with acute myelogenous and acute lymphoblastic leukemia for whom conventional therapy has failed. III. Confirm that aminopterin can be administered for four consecutive weeks when followed with minimal leucovorin calcium rescue and determine the minimal amount of leucovorin calcium required for each patient. IV. Confirm bioavailability data on oral aminopterin by performing limited sampling pharmacokinetics. V. Correlate blast uptake of aminopterin in vitro with clinical response.

OUTLINE: This is an open label study. Patients are stratified according to age and type of leukemia: Stratum I: Under 20 years old with acute lymphoblastic leukemia (ALL) in second or greater relapse Stratum II: Greater than 20 years old with ALL in first or greater relapse Stratum III: Patients of any age with acute myelogenous leukemia (AML) in first or greater relapse Patients receive aminopterin every 12 hours for 2 doses weekly for 4 weeks. Aminopterin is administered intravenously over 20 minutes for the first, second, and fourth doses, and orally for the third dose. The fifth and all subsequent doses are administered orally if bioavailability is acceptable. Patients receive oral leucovorin calcium every 12 hours for 2 doses beginning 24 hours after the last dose of aminopterin each week. If toxicity is limited for 2 consecutive weeks, the dose of leucovorin calcium is decreased to 1 dose administered 24 hours after the last dose of aminopterin each week. If this schedule is tolerated for 2 consecutive weeks, then leucovorin calcium is discontinued. Patients continue therapy for up to 15 months in the absence of disease progression or unacceptable toxicity. Patients are followed every 6 months.

PROJECTED ACCRUAL: This study will accrue a maximum of 25 patients per stratum, for a total of 75 patients, within 3 years.
