Clinical Trial Summary

The anticoagulants have been developed with new generation for FDA-approved indications including treatment and prevention of venous, pulmonary, and systemic thromboembolism. While the prescription of new oral anticoagulants (NOAC) has increasingly and largely replaced warfarin in accordance of better efficacy and safety, there are still adverse effects, including incidental minor and major bleeding, and inefficacy in thrombosis prevention. The overarching goal of this study is to develop a Pharmacogenomics Platform that is specifically designed for NOACs, in order to optimize and personalize the prescription and to facilitate the precision medicine.


Description:

Pharmaceutical companies have developed new oral anticoagulants (NOACs) to replace warfarin for prevention of systemic thrombo-embolization and embolic stroke in patients with atrial fibrillation or other thromboembolism diseases. The sale of NOACs has been increasing globally as the prevalence of atrial fibrillation increases in countries with aging population. Patients with high thromboembolism risk are also at high risk for major bleeding. The conservative strategy is not good for that more patients on reduced dose of NOACs had stroke. The clinical dilemma is how to justify the efficacy of NOACs in stroke prevention without encountering the incidental major bleeding from side effects. In order to solve this dilemma, the comprehensive evaluation of risk for thromboembolism, risk of bleeding, and genetic background on related to drug pharmacokinetics and response is essential. The primary goal of this project is to combine the clinical data and genetic information to develop a drug response evaluation platform to facilitate personalized and precision medicine for NOACs prescription. Pharmacogenomics elucidates the drug response and side effect on the basis of individual genetic background. This proposed project will enroll clinical patients who have atrial fibrillation and indications for the prescription of NOACs. The information will be collected for clinical demographics, medical history of embolic stroke, thromboembolism events, any bleeding events, and concurrent use of other medicines. Peak level of NOAC in use, and post-drug coagulation test will be performed. The above data will be integrated for the pharmacogenomic analysis with multiple genes (CES1, ABCB1, SLCO1B1, CYP2C9*2, CYP2C9*3, VKORC, CYP3A4, MMP-9, ALOX5AP, MTHFR, FGB and eNOs). The single nucleotide polymorphism (SNPs) of gene clusters will be derived from this clinical study. These output results will be used to optimize the gene-array product that is specifically-designed for NOACs prescription. The NOACs-specific gene-array for a precision prescription will be developed to help physicians to choose the right NOAC and the best dose for individualized patients. This tool will maximize thromboembolism prevention from the NOACs prescription along with the minimization of NOACs side effects. The product will be commercialized with great potential for the global market.
