Study of the Effect of Dapagliflozin on the Pharmacokinetics of Warfarin or Digoxin in Healthy Subjects

• Status: Completed
• Trial end date: 2009-08-01

Summary

The purpose of this study is determine that Dapagliflozin has no effect on the pharmacokinetics (PK) or pharmacodynamics (PD) of warfarin when dapagliflozin is coadministered with warfarin. Also, that Dapagliflozin has no effect on the PK of digoxin when dapagliflozin is coadministered with digoxin.

• Glucosuria at screening or dosing

• Abnormal liver functions tests (ALT, AST or total bilirubin > 10% above ULN) at screening or dosing

• History of diabetes mellitus

• History of heart failure

• History of renal insufficiency

• History of recurrent (defined as 3 occurrences per year) or recent vulvovaginal mycotic infections

• Positive urine screen for drugs of abuse either at screening or before dosing
