RATIONALE: CEP-701 may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
PURPOSE: This phase I trial is studying the side effects and best dose of CEP-701 in treating young patients with recurrent or refractory high-risk neuroblastoma.
Full description
OBJECTIVES:
Primary
Secondary
OUTLINE: This is an open-label, dose-escalation, multicenter study.
Patients receive oral CEP-701 twice daily* on days 1-5, 8-12, 15-19, and 22-26. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
NOTE: *On day 1 of course 1 only, patients receive oral CEP-701 once instead of twice.
Cohorts of 3-6 patients receive escalating doses of CEP-701 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, the dose level is expanded up to 9 patients.
PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.
