Phase I Trial Of Escalating Oral Doses Of SCH 66336 In Pediatric Patients With Refractory Or Recurrent Brain Tumors


- Determine the qualitative and quantitative toxicity of SCH 66336 in children with
recurrent or progressive brain tumors.

- Estimate the maximum tolerated dose of this drug in these patients.

- Describe the pharmacokinetics of this drug with and without dexamethasone in these

- Investigate the efficacy of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive oral SCH 66336 twice daily. Treatment repeats every 4 weeks for a total of
26 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 1-6 patients receive escalating doses of SCH 66336 until the maximum tolerated
dose (MTD) is determined. The MTD is defined as the dose at which it is predicted that 20%
of patients may experience dose-limiting toxicity. An additional 6 patients are treated at
the determined MTD.

Patients are followed within 30 days of the last administration of the study drug and then
for up to 3 months.

PROJECTED ACCRUAL: Approximately 25 patients will be accrued for this study.
