Summary

The purpose of this study is:

1. To determine the proportion of Asian patients achieving a target area under the curve (AUC) of 20-24 mg.h/L using a pharmacokinetically guided 5-fluorouracil (5-FU) dose
2. To determine the safety and tolerability of dose adjusted 5-FU
3. To correlate 5-FU pharmacokinetics with gene variants associated with the 5-FU pathway and with clinical outcomes

Based on Western data, levels of 5-FU are highly variable when doses are based on BSA. A relationship between systemic plasma levels of 5-FU and treatment toxicity and efficacy exists. Whilst pharmacokinetically-guided dose management has been shown to improve 5-FU efficacy and tolerance, there is currently no data in Asian patients using this approach. Using pharmacokinetically guided 5-FU-dose adjustment, the investigators hypothesize the proportion of Asian patients achieving a target AUC of 20-24 mg.h/L is similar to that of Caucasians.

METHODS:

This is an open, non-randomised single center Phase II study evaluating dose adjusted 5-FU in patients receiving de Gramont, FOLFIRI or mFOLFOX-6 schedules.

Conditions

  • Cancer (Advanced Stage)

Interventions

DRUG

5-Fluorouracil

Chemotherapy will be one of the following: 1. de Gramont: folinic acid 400mg/m2 day 1, 5-FU 400 mg/m2 bolus on day 1 followed by 46 hour continuous infusion of 5-FU 2400mg/m2. 2. FOLFIRI: Irinotecan 180mg/m2 on day 1, folinic acid 400mg/m2 day 1, 5-FU 400 mg/m2 bolus on day 1 followed by 46 hour continuous infusion of 5-FU 2400mg/m2. 3. Modified FOLFOX-6: Oxaliplatin 85mg/m2 on day 1, folinic acid 400mg/m2 day 1, 5-FU 400 mg/m2 bolus on day 1 followed by 46 hour continuous infusion of 5-FU 2400mg/m2.
