SeaStar Medical Ships First QUELIMMUNE Product Order to U.S. Distribution Partner

DENVER, July 12, 2024 (GLOBE NEWSWIRE) -- SeaStar Medical Holding Corporation (Nasdaq: ICU) (SeaStar Medical) reports the initial commercial sale of QUELIMMUNE^™-Pediatric to its U.S. license and distribution partner, Nuwellis, Inc. QUELIMMUNE is SeaStar Medical’s Selective Cytopheretic Device-Pediatric (SCD-PED), a patented cell-directed extracorporeal therapy that selectively targets the most highly activated neutrophils and monocytes responsible for hyperactive immune response. QUELIMMUNE is approved by the U.S. Food and Drug Administration (FDA) as a Humanitarian Use Device (HUD) under a Humanitarian Device Exemption (HDE) to treat pediatric acute kidney injury (AKI) in patients weighing 10 kilograms or greater with sepsis or a septic condition requiring kidney replacement therapy (KRT).

“It’s highly gratifying to ship our first commercial QUELIMMUNE product order to Nuwellis for these patients,” said Eric Schlorff, CEO of SeaStar Medical. “QUELIMMUNE is a best-in-class therapy that across two pediatric clinical studies has been shown to have a probable benefit of reducing mortality and decreasing dialysis dependency in these severely ill children. We expect prestigious pediatric hospitals to meet the HDE requirements this quarter, with a more robust commercial rollout in the fourth quarter of 2024.”

QUELIMMUNE consists of a SCD-PED cartridge and blood tubing set that are connected in-line to an existing hemodialysis delivery system’s extracorporeal continuous KRT circuit in a process that takes about 15 minutes. The Company expects that, on average, a full course of treatment for children with AKI will require three to seven days of treatment with the disposable SCD-PED cartridge being replaced every 24 hours.

Each year in the U.S., approximately 4,000 children with AKI require continuous KRT, with a mortality rate of approximately 50%. Many of those who survive experience long-term complications that can include chronic kidney disease and a lifetime of dialysis. Pooled analysis from two non-controlled studies, one of which was funded by the FDA office of Orphan Products Development, showed that children with AKI weighing 10 kilograms or more requiring continuous KRT treated with QUELIMMUNE had a 77% survival rate with no dialysis dependency at 60 days, and had no device-related serious adverse events or device-related infections.

SeaStar Medical is actively enrolling patients in the pivotal adult NEUTRALIZE-AKI clinical trial. The adult AKI population is 50 times greater than the pediatric population, which the Company believes represents a multibillion-dollar market opportunity.

About Hyperinflammation

Hyperinflammation is the overproduction or overactivity of inflammatory cells that can lead to damage of vital organs. It occurs when the body overproduces inflammatory effector cells and other molecules that can be toxic, damaging to vital organs and result in multi-organ failure and even death. This is known as the cytokine storm.

About the Selective Cytopheretic Device (SCD)

The SCD is a patented cell-directed extracorporeal device that employs immunomodulating technology to selectively target proinflammatory neutrophils and monocytes during continuous kidney renal therapy (CKRT) and reduces the hyperinflammatory milieu including the cytokine storm that causes inflammation, organ failure and possible death in critically ill patients. Unlike pathogen removal and other blood-purification tools, the device is integrated with CKRT hemofiltration systems to selectively target and transition proinflammatory monocytes to a reparative state and promote activated neutrophils to be less inflammatory. QUELIMMUNE selectively targets the most highly activated proinflammatory neutrophils and monocytes. These cells are then returned back into the body through the blood, and the body is signaled to lower its inflammatory environment and focus on repair. This unique immunomodulation approach may promote long-term organ recovery and eliminate the need for future KRT, including dialysis.
