Nafamostat Efficacy in Phase 3 Registrational CRRT Study (NEPHRO)

October 13, 2025 updated by: Talphera, Inc

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

A prospective, randomized, placebo-controlled clinical study to investigate the safety and efficacy of Niyad (nafamostat mesylate) for anticoagulation of extracorporeal blood circulating through a dialysis filter in patients undergoing CRRT who cannot tolerate heparin or are at higher risk for bleeding.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients in intensive care units with acute kidney injury are often too frail to undergo the rapid fluid shifts that accompany intermittent hemodialysis. Continuous renal replacement therapy (CRRT) allows a more gentle continual dialysis, more similar to regular kidney function. Anticoagulation of the CRRT circuit can reduce clotting of the filter, which can lead to less filter changes and possibly less transfusions. Niyad (nafamostat mesylate), an anticoagulant with an ultra-short half-life of 8 minutes, is approved for use in South Korea and Japan for anticoagulation of the CRRT circuit. For patients who cannot tolerate heparin or who are at a high risk of bleeding, nafamostat may be an optimal anticoagulant to infuse into the CRRT circuit as the short half-life should minimize patient exposure. The primary objective of this study is to measure the anticoagulation efficacy of Niyad in the CRRT circuit versus placebo. Evaluation of the safety of Niyad in patients undergoing CRRT versus placebo will also be performed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
