Food Effect Study on Pharmacodynamic and Bioavailability of Clopidogrel 300/75 mg in Healthy Subjects

Phase 1
Completed
Conditions
Healthy
Interventions
Drug: Matching placebo
Registration Number
NCT01129271
Lead Sponsor
Sanofi
Brief Summary

Primary objective:

* Investigate the potential food effect on Adenosine diphosphate(ADP)-induced platelet aggregation after 5-day repeated doses of clopidogrel (300 mg loading dose followed by 4 days 75 mg/day) in healthy subjects

Secondary objectives are to investigate the potential food effect on:

* ADP-induced platelet aggregation after 300 mg loading dose of clopidogrel

* Pharmacokinetic profiles of clopidogrel and its active metabolite after 5-day repeated doses of clopidogrel

Detailed Description

The total duration per subject is 8-9 weeks broken down as follows:

* Screening: 2 to 21 days before the first dosing

* Fed period: 7 days including 5 treatment days

* Washout: at least 14 days after last dosing

* Fasted period: 7 days including 5 treatment days

* End of study: 7 to 10 days after the last dosing
