This trial is active, not recruiting.

Condition unspecified adult solid tumor, protocol specific
Treatments irinotecan hydrochloride, pharmacogenomic studies, pharmacological study
Phase phase 1
Sponsor National Cancer Centre, Singapore
Start date June 2008
Trial size 18 participants
Trial identifier NCT00731276, CDR0000601207, SINGAPORE-NCC0703


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.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
The study has four type of regimens, and dosing of irinotecan depends on genotype of patient. Four Regimens are: Weekly Irinotecan (Irinotecan given at day 1, 8 and 15) every four weekly Weekly Xeliri ( Irinotecan given at day 1, 8 and 15)+ (Xeloda tabs 2000mg/m2 consumed over 14 days) every three weekly Three-weekly Xeliri (Irinotecan given at day 1 only) + (Xeloda tabs 2000mg/m2 consumed over 14 days) every three weekly 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

Additional Information

Official title Phase I Study to Investigate Genotype-based Dose Individualization of Irinotecan in Asian Cancer Patients
Principal investigator Su Pin Choo, MD
Description 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.
