Impact of Anti-platelet Drug Exposure on Platelet mRNA Splicing in Healthy Subjects

Investigation of Anti-platelet Drug Single Dose Exposure on Platelet mRNA Splicing in Healthy Subjects

The purpose of this pilot study is to determine how the anti-platelet drug, ticagrelor, impacts platelet mRNA splicing after a single loading dose in 10 healthy participants. These results will be valuable in that they will help inform our analysis of platelet RNA splicing after a thrombotic event.

There is nothing known on how differential splicing in platelets is impacted by of P2Y12 inhibition by anti-platelet agents. Consequently, the focus of this longitudinal pilot study will be to determine the impact of a single ticagrelor loading dose (180 mg), our "model" anti-platelet drug, on platelet RNA splicing in 10 healthy individuals.

It will test the hypothesis that ticagrelor exposure does not significantly alter platelet mRNA splicing. It will involve administering a single loading dose (180 mg) of ticagrelor to healthy volunteers.
