Talphera Announces First Patient Enrolled in the Registrational Trial Evaluating Nafamostat for Anticoagulation of the Extracorporeal Circuit

The safety and effectiveness of nafamostat is being assessed in the NEPHRO CRRT registrational trial in 166 patients at up to 14 clinical sites

Primary endpoint in the NEPHRO CRRT study is measured over the first 24 hours, with patients completing the study after 72 hours

Dr. Stuart Goldstein, a world-renowned nephrologist, is the first physician to enroll a patient in the NEPHRO CRRT study

SAN MATEO, Calif., Aug. 19, 2024 /PRNewswire/ -- Talphera, Inc. (Nasdaq: TLPH), ("Talphera"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced the first patient has been enrolled in the NEPHRO CRRT study.

The NEPHRO CRRT registrational study will enroll 166 patients undergoing continuous renal replacement therapy (CRRT) at up to 14 clinical sites across the United States. The primary endpoint of the study is the mean post-filter activated clotting time for circuits infused with nafamostat versus placebo over the first 24 hours.

"We are excited to be able to offer participation in this nafamostat study to our patients requiring CRRT," stated Stuart Goldstein, M.D., Professor of Pediatrics and Director of the Center for Acute Care Nephrology at Cincinnati Children's Hospital Medical Center. "Nafamostat, if approved following this trial, will be a valuable addition to our anticoagulant options for many patients."

"We are pleased the first patient was enrolled in the study last week. Nafamostat has the potential to address disadvantages of the currently available U.S. products used for anticoagulation of the extracorporeal circuit. Enrolling the first patient in the NEPHRO study is the first of what we believe will be several important milestones for Talphera," stated Dr. Shakil Aslam, Chief Development Officer at Talphera. "Nafamostat has been used, and is a standard of care, in Japan and South Korea for over 30 years and we're excited about the prospects of making nafamostat available to healthcare providers in the United States, if approved," continued Dr. Aslam.

About Niyad and nafamostat

Nafamostat is a broad spectrum, synthetic serine protease inhibitor with anticoagulant, anti-inflammatory and potential anti-viral activities. Niyad™ is a lyophilized formulation of nafamostat and is currently being studied under an IDE, as an anticoagulant for the extracorporeal circuit, and has received Breakthrough Device Designation Status from the FDA. Talphera's registrational study of Niyad™ is named the NEPHRO CRRT (Nafamostat Efficacy in Phase 3 Registrational Continuous Renal Replacement Therapy) study. An ICD-10 procedural code, XY0YX37, has been issued for the extracorporeal introduction of nafamostat. The ICD-10 code is a specific/billable code that can be used to indicate a procedure. LTX-608 is a proprietary nafamostat formulation for direct IV infusion that may be investigated and developed for the treatment of acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), acute pancreatitis or as an anti-viral treatment, amongst other potential targets.

About the NEPHRO CRRT Study

The NEPHRO Study, which has received central IRB approval, is designed as a prospective, double-blinded trial to be conducted at up to 14 U.S. hospital intensive care units. The study will enroll and evaluate 166 adult patients undergoing renal replacement therapy, who cannot tolerate heparin or are at risk for bleeding. The primary endpoint of the study is mean post-filter activated clotting time using Niyad versus placebo over the first 24 hours. Key secondary endpoints include filter lifespan, number of filter changes over 72 hours, number of transfusions over 72 hours and dialysis efficacy (based on urea concentration) over the first 24 hours.
