Thromboembolic diseases are diseases caused by abnormal blood clots formed in blood vessels of humans and animals during survival, and clinically may be manifested as myocardial infarction, stroke, deep Vein Thrombosis (DVT), pulmonary embolism, atrial fibrillation, cerebral infarction, etc., taking millions of people worldwide each year. Factor XI (FXI) is a plasma serine protease zymogen necessary for maintaining the endogenous pathway, and activated to form activated factor XIa (FXIa) plays a key role in the amplification of the coagulation cascade. Therefore, drugs against FXIa targets block endogenous pathways and inhibit amplification of the coagulation cascade, thus having antithrombotic effects.
The reported FXIa inhibitors mainly comprise monoclonal antibodies, antisense oligonucleotides, chemical small molecules, polypeptides or protein or polypeptide mimics and the like. Currently, milvexin, developed in conjunction with robustly, has completed clinical phase II trials, which have shown less risk of bleeding. Phase I clinical trials of the intravenous injection of the small molecule FXIa inhibitor BMS-962122 have been completed and development has been suspended. The small molecule oral FXIa inhibitor ONO-7684 developed by Japan Kochia company enters clinical phase I study. BAY-2433334 developed by Bayer has completed a clinical phase II trial and is currently the most promising small molecule FXIa inhibitor. The monoclonal antibody and the antisense oligonucleotide need to be injected and administrated, and have the defects of high price, slow effect, possibly difficult control and the like, and the chemical small molecules have the advantages of relatively good oral bioavailability, better patient compliance and the like.
Therefore, the research and development of new FXIa small molecule inhibitor drugs with safety, effectiveness, good specificity and strong activity can be used for overcoming the defect that the current clinical anticoagulation anti-thrombus drugs are easy to cause bleeding complications and meeting the clinical unmet demands.
