Summary

Hypothesis:

Patients with TYMS 2R/2R or 2R/3R appear to be more sensitive to fluoropyrimidines, conferring a higher risk of grade 3-4 fluoropyrimidine related toxicity and a higher response rate compared with 3R/3R. The genotype 3R/3R is more common in East Asia and is associated with greater tolerability to fluoropyrimidine as measured by lower toxicity but also lower response rates. As sensitivity to fluoropyrimidine appears to be affected by TYMS genotype, we hypothesise that patients with TYMS 3R/3R are more tolerant to standard doses of capecitabine and require higher doses to overcome fluoropyrimidine resistance. We designed this study to develop TYMS genotype specific dosing of capecitabine.

Aims:

1. To determine the maximal tolerated dose (MTD) of capecitabine twice a day for two weeks followed by one week rest period (intermittent schedule) in patients with the advanced/ and or metastatic cancer based on TYMS genotype.
2. To determine a suitable phase II dose of intermittent schedule capecitabine.
3. To determine the safety and toxicity of this regimen.
4. To perform plasma pharmacokinetics of capecitabine.
5. To determine the relationship between genes of relevance in the fluoropyrimidine pathway with pharmacokinetics and toxicity.

DRUG

Capecitabine

Capecitabine (XELODA) is supplied as biconvex, oblong film-coated tablets for oral administration and will be obtained from NUH Cancer Centre pharmacy. Each light peach-colored tablet contains 150 mg capecitabine and each peach-colored tablet contains 500 mg capecitabine. Capecitabine is to be administered orally within 30 minutes after the end of a meal (breakfast, dinner). Tablets should be swallowed with about 200 mL of water (not fruit juices). Capecitabine will be administered for 14 days followed by a 7 day rest period.
