Key result

Factor XI/XIa inhibitors show promise for preventing clots without increasing bleeding vs standard anticoagulants.

Why the study?

Modern-day anticoagulants predispose patients to pathological bleeding, prompting research into Factor XI/XIa inhibitors to minimize bleeding risks while preventing clot formation.

Do Factor XI/XIa inhibitors prevent blood clot formation without increasing bleeding compared to modern-day anticoagulants in patients requiring anticoagulation?

Overview

May support enrollment in phase III trials for high-risk patients; leaves open net clinical benefit versus current anticoagulants.

Structured PICO

Do Factor XI/XIa inhibitors prevent blood clot formation without increasing bleeding compared to modern-day anticoagulants in patients requiring anticoagulation?

P
Population
Patients taking or requiring anticoagulants
I
Intervention
Factor XI/XIa (FXI) inhibitors
C
Comparator
Modern-day anticoagulants
O
Outcome
Prevention of blood clot formation and instances of spontaneous and/or pathological bleeding eventssafety

Factor XI/XIa inhibitors represent a novel approach to anticoagulation that may decouple thrombosis prevention from bleeding risk.

Cite This Study

Whiteson et al. (2023) conducted a review in Cardiovascular disease requiring anticoagulation. Factor XI/XIa inhibitors was evaluated. Factor XI/XIa inhibitors are an emerging class of anticoagulants in phase II and III trials that show promise in preventing blood clot formation without increasing bleeding events.
