Trial Information

Phase II Trial of Irinotecan in Children With Refractory Solid Tumors


I. Determine the efficacy of irinotecan in children with refractory CNS or solid tumors.

II. Assess the toxicity, pharmacokinetics, and pharmacodynamics of this regimen in this
patient population.

III. Determine patient UGT1A1 genotype and correlate genotype with toxicity and
pharmacokinetic parameters of this regimen in these patients.

OUTLINE: Patients are stratified according to type of solid tumor (Ewings/PNET vs
neuroblastoma vs osteosarcoma vs rhabdomyosarcoma vs other solid tumors excluding lymphomas
and brain tumors) or brain tumor (medulloblastoma/PNET vs brain stem glioma vs ependymoma vs
other CNS tumors).

Patients receive irinotecan IV over 60 minutes on days 1-5. Treatment repeats every 3 weeks
for at least 2 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed every 6 months for 4 years and then annually thereafter until death or
until patient enters another POG study.

Inclusion Criteria:

- Histologically or cytologically confirmed CNS or solid tumors recurrent or refractory
to standard therapy

- Platelet count greater than 100,000/mm^3

- Hemoglobin greater than 8 mg/dL

- Inadequate peripheral blood counts due to bone marrow infiltration allowed

- Bilirubin no greater than 1.5 mg/dL

- SGPT less than 5 times normal

- Creatinine normal

- Glomerular filtration rate at least 70 mL/min

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception during and for 6 months after study

- At least 3 weeks since prior immunotherapy and recovered

- No concurrent biologic therapy

- At least 3 weeks since prior chemotherapy (8 weeks since prior nitrosoureas) and

- No more than 2 prior chemotherapy regimens

- No other concurrent chemotherapy

- Prior topotecan allowed

- No prior irinotecan

- Concurrent dexamethasone for brain tumor patients allowed if on a stable or
decreasing dose for at least 2 weeks prior to study

- At least 3 weeks since prior endocrine therapy

- No other concurrent endocrine therapy

- See Disease Characteristics

- At least 8 weeks since prior extended radiotherapy (including evaluable lesions) and

- No prior total body radiotherapy

- No concurrent radiotherapy

- See Disease Characteristics

- At least 3 weeks since prior investigational agents

- No other concurrent investigational agents

- No concurrent anticonvulsants

- No concurrent medications that would interfere with the P-450 enzyme system function
(e.g., erythromycin, cimetidine, fluconazole)
