Talphera to Host Virtual Investor & Analyst Event to Discuss Niyad® for Use in Continuous Renal Replacement Therapy (CRRT), on March 23, 2026

SAN MATEO, Calif., March 18, 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 that it will host a virtual investor and analyst event on Monday, March 23, 2026 at 11:00 AM ET featuring Blaithin McMahon, PhD, MBBChr (Medical University of South Carolina) and Joao Teixeira, MD (University of New Mexico), principal investigators in Talphera's NEPHRO CRRT study evaluating Niyad for continuous renal replacement therapy (CRRT). To register, click here.

The experts will discuss their experience with CRRT, the anticoagulants being used during CRRT today, and how they see Talphera's nafamostat filling a need. Nafamostat is a broad spectrum serine protease inhibitor with anticoagulant, anti-inflammatory, and potential antiviral properties with a variety of applications in medically supervised settings and has been the standard of care for CRRT anticoagulation in Japan and South Korea for over three decades. The Company's lead product candidate, Niyad, a lyophilized form of nafamostat, leverages the ultrashort half-life of nafamostat and its potent anticoagulant effects for potential use as a regional anticoagulant during CRRT in patients who cannot tolerate heparin or who have an increased risk of bleeding. Heparin is the only FDA approved anticoagulant for use in CRRT but it is not safe for patients with a high risk of bleeding or heparin intolerance. Citrate, the only other anticoagulant being used for CRRT, is used off-label, is complex to administer, cannot be used in liver impaired patients, and is principally only used by large academic institutions with the resources to monitor administration.

A live question and answer session will follow the formal presentations.

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. 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 anti-viral treatment, amongst other potential targets.
