A Drug-Drug Interaction Study Between AZD9668 and Warfarin to Study the Effect of AZD9668 on the Metabolism and Effect of Warfarin

A Phase I, Open Label, Fixed Sequence, Single Centre Study in Healthy Volunteers to Investigate the Effects of Repeated Oral Doses AZD9668 on the Pharmacokinetics and Pharmacodynamics of a Single Dose of Warfarin

The primary purpose of this study is to determine whether the treatment with AZD9668 will affect the metabolism and effect of Warfarin.

Inclusion Criteria:

• Be a non-smoker or ex-smoker who has stopped smoking for >6 months prior to Visit 1.

Exclusion Criteria:

• Any clinically significant disease or disorder
• Subject predicted to have high sensitivity to warfarin based on CYP2C9 and VKORC1 genotypes
• Any clinically relevant abnormal findings in physical examination
