Irinotecan in Treating Children With Refractory or Progressive Solid Tumors
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase I trial to study the effectiveness of irinotecan in treating children who have refractory or progressive solid tumors.
Unspecified Childhood Solid Tumor, Protocol Specific
Drug: irinotecan hydrochloride
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Pediatric Phase I and Pharmacokinetic Study of Irinotecan|
|Study Start Date:||September 1998|
|Study Completion Date:||January 2005|
- Determine the maximum tolerated dose and dose-limiting toxicity of irinotecan in children with refractory or progressive solid tumors.
- Determine the pharmacokinetics of this drug and its metabolites (SN-38, SN-38G, and APC) administered with and without concurrent anticonvulsants in this patient population.
- Determine the benefit this drug offers this patient population.
OUTLINE: This is a dose-escalation, multicenter study. Patients are accrued into stratum 1 initially and into stratum 2 if stratum 1 closes due to dose-limiting toxicity of myelosuppression or diarrhea. Patients on anticonvulsants will be accrued into stratum 3 and must meet the eligibility criteria for the stratum that is open (stratum 1 or stratum 2). (Stratum 1 closed as of 2002-09-15).
Patients receive irinotecan IV over 90 minutes weekly for 4 weeks. Treatment repeats every 6 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) with and without anticonvulsants 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.
Patients are followed every 6 months for 4 years and then annually thereafter.
PROJECTED ACCRUAL: Approximately 20-25 patients will be accrued for this study.
