A Drug Interaction Study of Warfarin and Canagliflozin in Healthy Adult Volunteers

Phase 1
Completed
Conditions
Healthy
Interventions
Drug: Canagliflozin/Warfarin
Registration Number
NCT01195324
Lead Sponsor
Johnson & Johnson Pharmaceutical Research & Development, L.L.C.
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).
