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.

Condition Intervention Phase
Unspecified Adult Solid Tumor, Protocol Specific
Drug: irinotecan hydrochloride
Other: pharmacogenomic studies
Other: pharmacological study
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: Phase I Study to Investigate Genotype-based Dose Individualization of Irinotecan in Asian Cancer Patients

Arms Assigned Interventions
Four Regimens

The study has four type of regimens, and dosing of irinotecan depends on genotype of patient.

Four Regimens are:

  1. Weekly Irinotecan (Irinotecan given at day 1, 8 and 15) every four weekly
  2. Weekly Xeliri ( Irinotecan given at day 1, 8 and 15)+ (Xeloda tabs 2000mg/m2 consumed over 14 days) every three weekly
  3. Three-weekly Xeliri (Irinotecan given at day 1 only) + (Xeloda tabs 2000mg/m2 consumed over 14 days) every three weekly
  4. Two-weekly FOLFIRI (Irinotecan given at day 1 only) + (CI Fluorouracil 600mg/m2 over 22hrs, IV Folinic Acid 200mg/m2 over 2hrs and IVP Fluorouracil 400mg/m2) every two weekly
Drug: irinotecan hydrochloride Other: pharmacogenomic studies Other: pharmacological study

Detailed Description:



  • To determine the dose-limiting toxicity and maximum tolerated dose of irinotecan hydrochloride according to the genotype status of Asian patients with solid tumors.


  • 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.
