Evaluating nafamostat for anticoagulation in patients with acute kidney injury undergoing dialysis

A Randomized, Placebo-controlled, Double-blind, Multi-center Study of the Safety and Efficacy of Niyad in Patients Undergoing Continuous Renal Replacement Therapy (CRRT) Who Cannot Tolerate Heparin or Are at a Higher Risk for Bleeding

Not applicable Interventional Talphera, Inc · NCT06150742

What this trial studies

This clinical trial investigates the safety and efficacy of nafamostat mesylate (Niyad) as an anticoagulant in patients undergoing continuous renal replacement therapy (CRRT) who cannot tolerate heparin or are at higher risk for bleeding. The study is a prospective, randomized, placebo-controlled design, focusing on patients in intensive care units with acute kidney injury. By using nafamostat, which has a very short half-life, the trial aims to minimize patient exposure while effectively preventing clotting in the CRRT circuit. The primary objective is to compare the anticoagulation efficacy of nafamostat against a placebo, along with evaluating its safety profile.

Who should consider this trial

Good fit: Ideal candidates for this study are patients in intensive care units requiring CRRT who cannot tolerate heparin or are at high risk for bleeding.

Not a fit: Patients weighing less than 50 kg, those receiving systemic anticoagulation, or those with active bleeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer anticoagulation option for critically ill patients undergoing dialysis, potentially reducing complications associated with heparin.

How similar studies have performed: While nafamostat is already approved for use in South Korea and Japan, this study represents a novel application in the context of CRRT in the United States.
