Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT01129427
Lead Sponsor
Sanofi
Brief Summary

Primary objective:

* Assess the effects of clopidogrel (300 mg loading dose followed by 4 days 75 mg/day) on Adenosine diphosphate (ADP)-induced platelet aggregation when given concomitantly with pantoprazole 80 mg/day compared to given alone in healthy male subjects

* Compare the pharmacokinetic profiles of clopidogrel active metabolite when clopidogrel is given either alone or concomitantly with pantoprazole

Secondary Objective:

* Compare the pharmacokinetic profiles of clopidogrel when clopidogrel is given either alone or concomitantly with pantoprazole

Detailed Description

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

* Screening: 2 to 21 days before the first dosing

* Period clopidogrel/placebo: 7 days including 5 days treatment

* Period clopidogrel/placebo + pantoprazole: 14 days including 12 days treatment

* Washout between periods: at least 14 days after last dosing with respect to clopidogrel treatment

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