Improving the Safety of Fluoropyrimidine-based Chemotherapy by Combined DPYD Genotype-guided and DPD Phenotype-guided Dose Individualization: The ALPE2U Study

Intervention Type: Drug
Study Type: Interventional
Sponsors: The Netherlands Cancer Institute, Leiden University Medical Center
Participants: 1440
In this study it will be determined whether the rate of severe toxicity associated with fluoropyrimidine treatment (capecitabine or 5-fluorouracil) can be significantly diminished by individualized dosing of fluoropyrimidines based on upfront phenotypic assessment of dihydropyrimidine dehydrogenase (DPD) deficiency.
