NUWE Newellis Inc

Nuwellis, Inc. (Nasdaq: NUWE), a medical technology company focused on transforming the lives of people with fluid overload, today announced its distribution partner, SeaStar Medical Holding Corporation (Nasdaq: ICU) (SeaStar Medical), has received Humanitarian Device Exemption (HDE) from the U.S. Food and Drug Administration (FDA) for Quelimmune™, its pediatric Selective Cytopheretic Device. Quelimmune provides a new therapy option for children weighing 10 kg or more who have acute kidney injury (AKI) and sepsis or a septic condition requiring continuous kidney replacement therapy (CKRT) in a hospital intensive care unit.

Nuwellis has an exclusive U.S. license and distribution agreement with SeaStar Medical to distribute Quelimmune and will market and distribute the device to nephrologists and intensive care physicians who are trained in pediatric extracorporeal therapy. With FDA HDE in place for Quelimmune, Nuwellis will begin commercial launch activities at targeted medical centers, with further commercial expansion expected later in the first half of 2024.

“Approximately 4,000 pediatric patients are hospitalized with AKI each year in the U.S.1 and these children are at grave risk when their bodies enter an uncontrolled inflammatory response called a cytokine storm. The unique technology behind Quelimmune has demonstrated a 50% mortality rate reduction in children with potentially deadly hyperinflammation,2” said Nestor Jaramillo, Jr., president and chief executive officer of Nuwellis. “The pediatric segment of our business has gained significant traction since the 2020 FDA clearance of our Aquadex device for pediatric patients weighing 20kg or more – growing at a compound annual growth rate (CAGR) of over 30%. The addition of Quelimmune to our current product offering will help save the lives of many pediatric patients and should have a meaningful impact on our revenue trajectory.”

“We’re proud to receive HDE for Quelimmune, designed to address the limitations of today’s therapeutic options for critically ill pediatric patients with cytokine storm-induced hyperinflammation,” said Eric Schlorff, chief executive officer of SeaStar Medical. “Through Nuwellis’ established relationships within pediatric nephrology and critical care, we look forward to bringing Quelimmune to market quickly to the patients who need it most.”

SeaStar Medical’s Quelimmune therapy is a patented, cell-directed extracorporeal device for managing cytokine storm-induced hyperinflammation. The therapy precisely targets and neutralizes activated toxic immune cells that drive cytokine storms (an overreaction of the immune system) that can ultimately cause organ damage and failure for critically ill patients. Clinical studies have demonstrated Quelimmune’s potential to eliminate dialysis dependency, shorten intensive care unit time, and restore the lives of critically ill pediatric patients. A non-controlled pivotal study funded by the FDA Office of Orphan Products Development demonstrated that those treated with Quelimmune had no device related adverse events, a 50% reduction in mortality rate, and no dialysis required at Day 60.2,3,4
