GENOCARE: A Prospective, Randomized Clinical Trial of Genotype-Guided Dosing Versus Usual Care

This is a prospective, randomized study designed to compare genotype-guided dosing to usual care in patients with pancreas cancer and colorectal cancer who are UGT1A1 intermediate metabolizers (*1/*28) (heterozygotes) and usual UGT metabolizers (*1/*1). All patients will be assessed for UGT1A1 genotype at screening and those with intermediate or usual UGT1A1 genotypes (*1/*28, *1/*1) will be randomized to genotype-guided dosing versus usual care.
