Summary: This article discusses the use of coagulation factor XI inhibitors in the treatment of patients with venous thromboembolism (clot; VTE).

Conclusion: In patients with venous thromboembolism (clot), treatment with coagulation factor XI inhibitors is safe and effective.


Thrombosis is the main cause of the development and progression of venous thromboembolism(VTE). Anticoagulant therapy is the cornerstone for the prophylaxis and treatment of VTE, and it has evolved mainly through indirect thrombin inhibitors, direct thrombin inhibitors, vitamin K antagonists and new oral anticoagulants. Although safety is improving, the risk of bleeding remains a non-negligible side effect of current anticoagulation therapy, especially in patients with higher bleeding risk. Studies of the coagulation pathway have found that FXI is not involved in the initiation of hemostasis, but promotes thrombus growth and stabilization primarily through feedback activation of FⅪ by thrombin. Further studies have found that inhibition of FⅪ significantly inhibits thrombus formation and only affects hemostasis slightly. Recent studies have confirmed the efficacy and safety of FⅪ inhibitors in the prevention of VTE in patients after knee replacement. In addition, the safety of FⅪ inhibitors has been further confirmed by the studies of FⅪ inhibitors in people with higher bleeding risk. FⅪ inhibitors may be the most promising anticoagulant drugs in the next decade.
