SAN MATEO, Calif., March 2, 2026 /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 50% patient enrollment of the NEPHRO-CRRT clinical trial.
"Over the course of 2025, with agreement from the FDA, we implemented significant changes to the NEPHRO CRRT clinical trial, including a nearly 60% reduction in the total number of patients to be enrolled and revising other enrollment criteria. In addition, we reviewed and updated our target profile for clinical sites to focus on medical ICUs and having nephrologists as our principal investigators. These changes have yielded positive results in enrollment rates, allowing us to achieve our 50% enrollment milestone with more than 90% of the patients from our new sites," said Vince Angotti, CEO of Talphera. "We're looking forward to completing the study, and anticipate filing our PMA this year to potentially have the only FDA approved regional anticoagulant for CRRT. We continue to receive feedback from physicians— that they desperately need a better CRRT anticoagulant. In just a few weeks, we are excited to have two key experts share their deep experience with CRRT at our planned virtual investor and analyst day," continued Angotti.

About the NEPHRO CRRT Study
The NEPHRO CRRT Study 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 70 adult patients undergoing renal replacement therapy, who cannot tolerate heparin or are at risk of bleeding. The primary endpoint of the study is the mean post-filter activated clotting time on Niyad versus placebo over the first 24 hours. Key secondary endpoints include the mean post-filter activated clotting time over 72 hours, 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.
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.
