New Anticoagulant with less Bleeding Risk―Asundexian Factor XI (Bayer)
Today’s anticoagulants (DOACs-Direct Oral Anticoagulants) have a residual risk of major bleeding of 1.5-3.6%/year. That means that after stopping a DOAC anticoagulant, the effects can continue to affect you for 1½ to 3½ years afterward.
The result is you continue to be at a higher risk of major bleeding even though you are no longer taking the anticoagulant.
Alarming, bleeding events remain a high risk for you.
These bleeding events are associated with increased mortality, high costs, and compromised adherence to treatment. Especially for patients 65 and older, anticoagulants increase the risk of hemorrhagic-type strokes. (For more about anticoagulants, see my post: Anticoagulants Increase Risk of Hemorrhagic-Type Strokes.)

Pacific-AF clinical trials
Drug to Reduce Bleeding Event in Clinical Trial
Currently the PACIFIC-AF clinical trials is studying Asundexian, a new anticoagulant. Asundexian is an oral factor XI (FXIa inhibitor). Early clinical results indicate that FXIa inhibition works to prevent stroke with reduced bleeding risk. Clinical trials and phases are continuing.
If FXIa inhibition proves to be safer and as effective as existing DOACs, it would be a major advance in stroke-prevention therapy.
