Développement clinique des thérapeutiques anti-facteur XII ciblant la thrombo-inflammation

The history of anticoagulation has evolved considerably, from non-specific drugs to molecules that directly target specific coagulation factors, such as direct oral anticoagulants (DOACs). Since last decade, DOACs are widely used in clinical practice because of their ease to use with favorable pharmacological profile and not requiring monitoring. New therapeutics targeting the contact phase of coagulation are currently under development, and could make it possible to prevent thrombotic risk without altering hemostasis, thereby reducing the risk of bleeding. Factor XII, being at the crossroads between hemostasis and inflammation, appears to be an interesting target that could limit thrombo-inflammation without increasing bleeding risk. The aim of this article is to summarize the main information concerning FXII inhibitors and to review the results of various clinical trials available to date, focusing on applications beyond hemostasis, such as in the management of hereditary angioedema.
