Effect of Free Ticagrelor Fraction on Platelet Membrane Post MI (PLATIME)
Population-Based Pharmacokinetic / Pharmacodynamic Modeling of the Effect of Free Ticagrelor Fraction on the Platelet Membrane in Post Myocardial Infarction Patients
The purpose of this study is to assess:
- the population pharmacokinetics of unbound ticagrelor and its metabolite in acute coronary syndrome patients treated by ticagrelor
- ticagrelor and its metabolite levels by LC-MS/MS
연구 개요
상세 설명
Ticagrelor is an anti-platelet agent of the cyclopentyltriazolopyrimidine class. It is administered by the oral route, rapidly absorbed (2-3 hours), and has a bio-availability estimated at around 36%. Contrary to other P2Y12 inhibitors, ticagrelor is not a pro-drug and does not need to be metabolized to exert is pharmacodynamic effect. It had been previously showed that stimulation of platelets by ADP or inhibitors of platelets by ticagrelor modified the organisation of the platelet membrane, with a re-distribution of cholesterol and P2Y12 receptors towards the lipid rafts. This suggests that lipid membranes and cholesterol may play an important role in the anti-platelet activity of ticagrelor.
In this context, the aim of the study is to assess:
- the population pharmacokinetics of unbound ticagrelor and its metabolite in acute coronary syndrome patients treated by ticagrelor
- ticagrelor and its metabolite levels by LC-MS/MS.

Study cohort
Adult (>18 years, <90 years) patients admitted and treated for acute myocardial infarction, and whose treatment includes ticagrelor in association with aspirin. Blood samples will be taken at 3 timepoints between two doses of ticagrelor (taken at 12 hours interval). |
3 blood samples, for a maximum of 60mL, will be taken at 0-3h, 3-6h and >6h, between two doses of ticagrelor (taken at 0 and 12 hours).
