Detailed Description:

OBJECTIVES:

Primary

  • Determine the maximum tolerated dose and toxicity profile of tipifarnib in pediatric patients with refractory leukemia.
  • Determine the pharmacokinetics of this drug in these patients.
  • Determine the toxicity profile of this drug in these patients.

Secondary

  • Analyze the gene expression profile of leukemic blasts from these patients before and after treatment with this drug.
  • Determine circulating levels of nerve growth factor and correlate these levels with clinical neurotoxicity from this drug in these patients.

OUTLINE: This is an open-label, dose-escalation study.

Patients receive oral tipifarnib every 12 hours on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of tipifarnib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. At least 9 additional patients are treated at the MTD.

PROJECTED ACCRUAL: A total of 12-34 patients will be accrued for this study within 1-2 years.
