Imapct of bioMarkers on Pharmacodynamics and Bleeding Risk of Direct Oral AntiCoagulants and Ticagrelor Study II (IMPACT 2)

Individual differences in drug efficacy and adverse reactions are common in the clinical application of drugs. Individual differences are caused by many factors, among which genetic factors account for more than 20%. Novel oral anticoagulant drugs (NOACs, including rivaroxaban, apixaban, edoxaban, dabigatran, etc.) and novel antiplatelet drug ticagrelor have the advantages of convenient use and no need for monitoring. But novel oral antithrombotic drugs also increase the risk of bleeding, and there is currently a lack of effective antagonists when antithrombosis is excessive or emergency surgery is required. At present, there are few studies on the causes of individual differences in novel antithrombotic drugs, and there is a lack of predictable biomarkers or drug genotypes, especially in China. Therefore, on the basis of previous studies on NOACs and ticagrelor individualized medication cohorts, this study plans to establish a validation cohort for novel antithrombotic drugs bleeding related biomarkers, conduct multi-omics testing and long-term follow-up, and explore markers related to pharmacodynamics of antithrombotic drugs, adverse bleeding reactions and clinical outcomes.
