A Drug Interaction Study of Warfarin and Canagliflozin in Healthy Adult Volunteers
- Conditions
- Healthy
- Interventions
- Drug: Canagliflozin/Warfarin
- Registration Number
- NCT01195324
- Brief Summary
The purpose of the study is to assess the effect of multiple oral doses of canagliflozin on a single oral dose of warfarin.
- Detailed Description
This is an open-label (volunteers will know the names of treatments they are assigned) single-center study of canagliflozin (JNJ-28431754) and warfarin in healthy adult volunteers. Canagliflozin is a drug currently under development to lower blood sugar levels in patients with type 2 diabetes mellitus and warfarin is an approved anticoagulant (ie, a drug that stops blood from clotting). After an overnight fast (without eating food) of at least 10 hours, volunteers will receive Sequence 1 (canagliflozin 300 mg, orally, once daily on Days 1-12 with a single, oral 30 mg dose of warfarin on Day 6 \[Treatment A\] followed 14 days later by a single, oral 30 mg dose of warfarin on Day 1 \[Treatment B\]) OR Sequence 2 (Treatment B followed 14 days later by Treatment A).
