Case Series of Three Critically Ill Children with Acute Kidney Injury Safely Treated with SeaStar Medical’s Selective Cytopheretic Device Published in the Journal Blood Purification

DENVER, Aug. 29, 2023 (GLOBE NEWSWIRE) — SeaStar Medical Holding Corporation (Nasdaq: ICU), a medical device company developing proprietary solutions to reduce the consequences of hyperinflammation on vital organs, announces the publication of a case series of three critically ill children with Shiga-toxin-associated hemolytic uremic syndrome (STEC-HUS), a severe cause of acute kidney injury (AKI), who were safely treated with SeaStar Medical’s Selective Cytopheretic Device for children (SCD-PED).

All three children were in the ICU at two different hospitals and treated with continuous kidney replacement therapy (CKRT). Each show gradual improvement following treatment with the SCD-PED and normalization or near normalization of kidney function at 60-day follow up. The article, “Hemolytic Uremic Syndrome-Induced Acute Kidney Injury Treated via Immunomodulation with the Selective Cytopheretic Device: Cases of STEC-HUS Treated with Immunomodulation via SCD CRRT Filter,” (H. Rhodes Hambrick, et al.) was published in the peer-reviewed journal Blood Purification. An abstract of the article is available here.

“Although most critically ill children with STEC-HUS-associated AKI with multiorgan failure recover kidney function, about 5% die and 30% develop chronic renal morbidity,” said Stuart Goldstein, MD, Director of the Center for Acute Care Nephrology at Cincinnati Children’s Hospital and senior author of the paper. “HUS pathophysiology includes activated neutrophils damaging vascular endothelial cells. We found that immunomodulatory treatment with the SCD-PED in these three cases was associated with improvements in multisystem disease of STEC-HUS-induced AKI and was well-tolerated without any device-related adverse events.”

“The continued observation of favorable experience with the SCD-PED for critically ill children with AKI is highly encouraging,” said Kevin Chung, MD, Chief Medical Officer of SeaStar Medical. “We are working diligently to make this potentially life-saving therapy more broadly available to critically ill children with AKI and achieving our corporate goal of improving patient outcomes and saving lives.”

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. Unlike pathogen removal and other blood-purification tools, the SCD selectively targets the most highly activated proinflammatory neutrophils and monocytes. The Company has observed that these most highly activated immune cells are turned off in a low calcium environment. The SCD therapy mimics nature by creating a unique micro-environment, attracting these highly activated effector cells and neutralizing them in such an environment. These cells are then returned back into the body through the blood, and the body is signaled to focus on repair.

About SeaStar Medical

SeaStar Medical is a medical technology company that is redefining how extracorporeal therapies may reduce the consequences of excessive inflammation on vital organs. SeaStar Medical’s novel technologies rely on science and innovation to provide life-saving solutions to critically ill patients. The Company is developing and commercializing cell-directed extracorporeal therapies that target the effector cells that drive systemic inflammation, causing direct tissue damage and secreting a range of pro-inflammatory cytokines that initiate and propagate imbalanced immune responses.
