Primary Outcome Measures:
  • Survival [ Time Frame: Length of study ] [ Designated as safety issue: Yes ]
    To estimate the maximum tolerated dose (MTD) of STI571 administered orally once daily without interruption to children with recurrent Ph+ leukemia.


Secondary Outcome Measures:
  • Dose-limiting toxicities [ Time Frame: Length of study ] [ Designated as safety issue: Yes ]
    To determine the dose-limiting toxicities (DLT) of STI571 given on this schedule.

  • Characterize the pharmacokinetic behavior [ Time Frame: Length of study ] [ Designated as safety issue: Yes ]
    To characterize the pharmacokinetic behavior of STI571 in children with recurrent Ph+ leukemia.

  • Define the anti-leukemic activity of STI571 [ Time Frame: Length of study ] [ Designated as safety issue: No ]
    To preliminarily define the anti-leukemic activity of STI571 within the confines of a Phase I study.

Detailed Description:

OBJECTIVES:

  • Determine the maximum tolerated dose and dose-limiting toxicity of imatinib mesylate in patients with recurrent Philadelphia chromosome-positive leukemia.
  • Characterize the pharmacokinetic behavior of this drug in this patient population.
  • Determine preliminarily the antileukemic activity of this drug in these patients.

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

Patients receive oral imatinib mesylate (STI571) once daily for 28 days. Treatment continues in the absence of unacceptable toxicity or disease progression.

Cohorts of 3-6 patients receive escalating doses of STI571 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Patients are followed every 6 months for 4 years and then annually thereafter.

PROJECTED ACCRUAL: A maximum of 32 patients will be accrued for this study within 3.5 years.
