Genetics of Response to Canagliflozin

Summary

Five daily doses of canagliflozin (300 mg) will be administered to healthy volunteers. Pharmacodynamic responses to canagliflozin will be assessed both at 2 days and 6 days after administration of the first dose of canagliflozin. A genome-wide association study (GWAS) will be conducted to search for genetic variants that are associated with each of the pharmacodynamic responses to canagliflozin.
