Assessing Pharmacokinetics and Pharmacodynamics of Daily Enteric-coated Aspirin in Patients With StablE Diabetes II
Montreal Heart Institute
30 participants

INTERVENTIONAL
Conditions
Summary
This phase 2 study will include patients suffering from type 2 diabetes mellitus and will first study their response to enteric coated aspirin at a dose of 80 mg per day for a 7-day period. Participants with an incomplete platelet inhibition after exposure to EC aspirin at doses of 80 mg once daily will be randomized to a random order of 3 different ASA regimens: EC ASA 162 mg once daily, EC ASA 81 mg twice daily and chewable ASA 40 mg twice daily. The aims are to determine the feasibility of a larger scale trial, and to determine the regimen associated with the lowest proportion of non-responders after randomization. Platelet function will be assessed at baseline and at day 7 of each arms of the study.
