APPEASED is a phase 1 open-label single arm pilot trial, aiming to determine the feasibility of a larger confirmatory randomized trial, and to characterize the prevalence of incomplete platelet inhibition after exposure to EC aspirin at doses of 80 mg once daily in patients with type 2 diabetes. The primary endpoint will be incomplete platelet aggregation in response to arachidonic acid at a concentration of 1mM, measured by LTA (Light Transmission Agregometry). For every platelet function assessment, serum salicylate concentration will also be measured. Upon the screening visit (day 0), blood will be drawn and baseline platelet function will be assessed. A 7 day supply of aspirin will be given to participants meeting the eligibility criteria. Participants will be instructed to take 1 dose of 80 mg of enteric coated aspirin per day at the same time every day. Upon day 7, participants will return for a second visit before the intake of their daily aspirin, and therefore 24 hours after the previous dose of aspirin was taken. Blood will be drawn and platelet function will be assessed in the same manner as described previously. Participants will then take their final dose of aspirin under supervision, and a final blood sample will be collected and platelet function will be assessed two hours later.
This phase 1 study will include patients suffering from type 2 diabetes mellitus and will study their response to enteric coated aspirin at a dose of 80 mg per day for a 7-day period. The aims are to determine the feasibility of a phase 2 larger scale trial, and to characterize the prevalence of incomplete platelet inhibition after exposure to EC aspirin at doses of 80 mg once daily. Platelet function will be assessed at baseline and a day 7.
