Brief Summary: Phase I trial to study the effectiveness of raltitrexed in treating children with refractory acute leukemia Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die
Detailed Description: OBJECTIVES
I Determine the maximum tolerated dose and dose limiting toxicity of raltitrexed given for three weeks to children with refractory acute leukemia
II Determine the incidence and severity of other toxic effects of this regimen in these patients
III Determine a safe and tolerable dose of raltitrexed administered in this manner to be used in phase II studies
IV Determine the pharmacokinetics of this regimen in these patients V Determine if plasma 2 deoxyuridine concentrations are associated with raltitrexed toxicity or pharmacokinetics
VI Evaluate the antitumor activity of raltitrexed against recurrent leukemia
OUTLINE This is a dose escalation study
Patients receive raltitrexed intravenously over 15 minutes once weekly for 3 weeks followed by 1 week of rest Treatment continues in the absence of disease progression and unacceptable toxicity
In the absence of dose-limiting toxicity DLT in the first cohort of 6 patients treated subsequent cohorts of 6 patients each receive escalating doses of raltitrexed on the same schedule If DLT occurs in 2 of 6 patients at a given dose level then dose escalation ceases and the next lower dose is declared the maximum tolerated dose
Patients are followed every 6 months for 4 years then annually thereafter
