Chronic hemodialysis patients exhibit an excessive cardiovascular risk and a marked increase in both thromboembolism and bleeding episodes. Factor XI inhibition may provide anticoagulation, with a low risk of bleeding, and several factor XI inhibitors, including fesomersen, an antisense oligonucleotide, are under development. Recently, a phase 2 study of fesomersen showed a good safety profile in chronic hemodialysis patients and suggested that clotting rates of the arteriovenous fistula and the dialysis circuit are lower.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
