Insights
New Factor XI (FXI) inhibitors offer a novel anticoagulant approach to prevent stroke. These agents target the coagulation contact pathway, addressing unmet needs in stroke prevention and bleeding risk.
Area of Science:
- Cardiovascular Medicine
- Hematology
- Neurology
Background:
- Stroke is a leading cause of death and disability globally.
- Antithrombotic therapies, including anticoagulants and antiplatelets, are crucial for stroke prevention.
- Current treatments face limitations regarding residual risk and bleeding complications.
Purpose of the Study:
- To review the evidence and future prospects of Factor XI (FXI) inhibitors.
- To explore FXI inhibitors as a novel anticoagulant strategy for stroke prevention.
- To evaluate their potential in managing cardioembolic and non-cardioembolic ischemic stroke.
Main Methods:
- Review of current scientific literature on FXI and FXII inhibitors.
- Analysis of the selective inhibition of the coagulation contact pathway.
- Examination of therapeutic implications for stroke prevention.
Main Results:
- Factor XI (FXI) and Factor XII inhibitors represent a new class of anticoagulants.
- Selective inhibition of the contact pathway offers a targeted approach.
- These agents show promise in addressing limitations of existing antithrombotic therapies.
Conclusions:
- FXI inhibitors may offer an additional therapeutic option for ischemic stroke prevention.
- They hold potential for both primary and secondary prevention in various stroke types.
- Further research is needed to establish their role in challenging clinical scenarios.
Abstract:
Stroke is one of the most common causes of mortality and disability worldwide. Antithrombotic therapy represents the mainstay in primary and secondary prevention, both in cardioembolic and non-cardioembolic stroke. Particularly, direct oral anticoagulants play a crucial role in atrial fibrillation, the most common cause of cardioembolic stroke, whereas single or dual antiplatelet therapy is preferred in non-cardioembolic stroke. However, the limitations related to the residual risk of cardioembolic or cerebrovascular events, and the risk of major bleeding, still represent unmet medical needs. To overcome them, new drugs inhibiting Factor XI (FXI) and Factor XII have been proposed, with a selective inhibition of contact pathway of coagulation, delineating a new anticoagulant approach. This review provides a summary of the currently available evidence and future perspectives on FXI inhibitors, that can represent an additional therapeutic option in the primary and secondary prevention of cardioembolic and non-cardioembolic ischemic stroke, also in challenging therapeutic contexts.
