A feasibility study of Irinotecan (CPT-11) by groups of Uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) polymorphisms in patients with metastatic colorectal cancer.

ABSTRACT: Interventions: Patients receive FOLFIRI with bevacizumab fixed 5mg/kg. (Treatment will be continued unless the disease progression, unacceptable toxicity, or consent withdrawal.) Definision of UGT1A1 polymorphisms groups: The homozygous group is patient with homozygous genotype of UGT1A1*28/*28 or UGT1A1*6/*6, with combined heterozygous genotypes of UGT1A1*28 and UGT1A1*6. The heterozygous group is patient with heterozygous genotype of either UGT1A1*28 or UGT1A1*6. The wild group is patients with no UGT1A1*28 and UGT1A1*6 mutation. CPT-11 dosage is wild and heterozygous:CPT-11 150mg/m2 homozygous:CPT-11 100mg/m2 Primary outcome(s): 1)incidence of adverse events 2)frequency of severe toxicity Study Design: Single arm Non-randomized

A genotype directed dose-finding study of Irinotecan (CPT-11) by groups of Uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) polymorphisms in patients with advanced metastatic colorectal cancer and gastric cancer.

Project description:Interventions: Administraion of CPT-11 is twice for 4 weeks on days 1 and 15. CPT-11 is reconstituted in >=250 mL of normal saline or 5% dextrose in water and infuse 90min on day 1 for pharmacokinetics, and 90min over on day15. CPT-11 adjusted dosage is determined from 50,75,100,125 or 150mg/sqm in the heterozygous group and the homozygous group by continual reassessment method. CPT-11 dosage is fixed at 150mg/sqm in the wild group.Definision of UGT1A1 polymorphisms groups: The homozygous group is patient with homozygous genotype of UGT1A1*28/*28 or UGT1A1*6/*6, with combined heterozygous genotypes of UGT1A1*28 and UGT1A1*6. The heterozygous group is patient with heterozygous genotype of either UGT1A1*28 or UGT1A1*6. The wild group is patients with no UGT1A1*28 and UGT1A1*6 mutation. Primary outcome(s): Maximum tolerated dose for the heterozygous group and the homozygous group, respectively. Incidence rate of dose limiting toxicities for the wild group. Study Design: Single arm Non-randomized

Study to Evaluate the Efficacy and Safety of FOLFIRI-AD in Patients With Metastatic Colorectal Cancer UGT1A Genotype 1

Project description:This study aims to use the corresponding pharmacogenetic analysis to increase the dose of irinotecan in the schemes commonly used standard chemotherapy in advanced colorectal cancer treatment first. The project aims to improve the therapeutic index of chemotherapy. This optimization is raised based on the administration of different doses of the drug depending on the genotype UGT1A1 gene. The research team proposes this project to demonstrate how the administration of high doses of irinotecan in the FOLFIRI scheme in patients with genotype UGT1A1 favorable (wild homozygous * 1 / * 1 and heterozygous * 1 / * 28), significantly improves the efficiency of the antineoplastic agent without significant increase in toxicity. Secondarily will assess the possible prognostic factors related to tolerance and efficacy. The primary objective is to evaluate the efficacy of high doses of irinotecan in the FOLFIRI scheme in patients with metastatic colorectal cancer with a favorable genotype UGT1A1 (wild homozygous * 1 / * 1 and heterozygous * 1 / * 28).

A multicenter phase II study of FOLFIRI as first-line chemotherapy for metastatic colorectal cancer with reduced starting dose of irinotecan in patients with homozygous for UGT1A1(FLIGHT1)

Project description:Interventions: On Day 1, patients treated with FOLFIRI therapy received a 2-hour intravenous infusion of CPT-11 (150 mg/m2) combined with 1-LV (200 mg/m2), followed by a rapid intravenous infusion of 5-FU (400 mg/m2), and then a 46-hour continuous infusion of 5-FU (2,400 mg/m2). This regimen comprised one course of therapy and was repeated once every 2 weeks. Cycles of treatment will be continued for this study until disease progression (PD) occurs. Patients will undergo UGT1A1 genotyping before starting to receive the protocol treatment. As recommended in the US prescribing information for Camptosar;, the starting dose of CPT-11 will be reduced to 100 mg/m2 in patients who are homozygous for the *28 allelic variant of UGT1A1 (further reduced to 75 mg/m2 in such patients aged 76-80 years). No dose adjustments will be made in patients who undergo UGT1A1 genotyping after starting to receive the protocol treatment. Primary outcome(s): (1)response rate (2)incidence and severity of adverse events Study Design: Single arm Non-randomized
