Evaluating Nafamostat Mesylate for Dialysis Patients at High Risk of Bleeding

The Safety of Nafamostat Mesylate for Patients With High Risk Bleeding Diathesis Undergoing Hemodialysis: A Pilot Study

NA · Wonju Severance Christian Hospital · NCT05874674

What this trial studies

This pilot study compares the safety and efficacy of Nafamostat Mesylate to low molecular weight heparin in patients undergoing hemodialysis who are at high risk for bleeding complications. The study aims to determine whether Nafamostat can provide a safer alternative for anticoagulation in this vulnerable population. Participants will be monitored for bleeding events and other complications during the treatment period. The study focuses on patients with specific bleeding risks, including those with low platelet counts and recent major surgeries.

Who should consider this trial

Good fit: Ideal candidates include dialysis patients with significant bleeding risks, such as low platelet counts and recent major surgeries.

Not a fit: Patients with active bleeding in major organs, cancer, liver cirrhosis, or those who are pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer anticoagulation options for dialysis patients at high risk of bleeding.

How similar studies have performed: While there is limited data on Nafamostat specifically in this context, similar studies have explored alternative anticoagulants in high-risk populations with varying degrees of success.
