Irinotecan in Treating Asian Patients With Solid Tumors
Phase I Study to Investigate Genotype-based Dose Individualization of Irinotecan in Asian Cancer Patients
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan in treating Asian patients with solid tumors.

Detaljerad beskrivning
OBJECTIVES:
Primary
- To determine the dose-limiting toxicity and maximum tolerated dose of irinotecan hydrochloride according to the genotype status of Asian patients with solid tumors.
Secondary
- To investigate the pharmacokinetics of irinotecan hydrochloride and its metabolites SN-38 and SN-38G.
- To evaluate time to tumor response, response duration, and time to progression in these patients.
OUTLINE: Patients are stratified according to genotype status (UGT1A1*28 vs UGT1A1*6)
Patients receive irinotecan hydrochloride IV once weekly for 3 weeks. Treatment repeats every 4 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Patients undergo blood sample collection periodically for pharmacogenetic, pharmacokinetic, and pharmacodynamic studies.
