SeaStar’s QUELIMMUNE Therapy Shows Promise in Halving Pediatric Sepsis Mortality Rates

In Press Release
June 27, 2025

SeaStar Medical Holding Corp. has announced significant advancements in the treatment of pediatric patients suffering from acute kidney injury (AKI) due to sepsis, with its QUELIMMUNE therapy. This humanitarian medical device, which received U.S. Food and Drug Administration approval in 2024, has been shown in clinical trials to reduce mortality rates from 50% to 25% among pediatric patients. The therapy targets the dysregulated innate immune response, specifically the cytokine storm, which is a critical factor in the progression of sepsis.

Dr. Kevin Chung, MD, Chief Medical Officer at SeaStar Medical, explained the mechanism behind QUELIMMUNE’s effectiveness. The device is designed to directly address the cytokine storm at its source, leading to significantly improved outcomes, particularly in the pediatric population. This breakthrough offers a new hope for families and healthcare providers dealing with the devastating effects of sepsis in children.

The impact of QUELIMMUNE was vividly illustrated in the case of Kurt, a young patient who faced a near-death experience due to complications from surgery. Treated at Cincinnati Children’s Hospital Medical Center, Kurt’s condition rapidly improved after receiving QUELIMMUNE therapy, allowing him to avoid more invasive treatments and eventually return to his normal activities, including golf. His recovery, described as ‘dramatic’ by Dr. Stuart L. Goldstein, MD, highlights the potential of QUELIMMUNE to change the trajectory of severe pediatric cases.

Kurt’s father, David, shared his family’s emotional journey, recalling how QUELIMMUNE therapy became their last hope. The improvement in Kurt’s condition was swift, with inflammatory markers showing daily progress, culminating in what David described as a ‘Christmas miracle’ when Kurt awoke from his coma. This personal story underscores the profound difference QUELIMMUNE can make in the lives of patients and their families.

Beyond its immediate life-saving potential, QUELIMMUNE also offers long-term benefits by reducing the need for chronic dialysis in survivors of AKI episodes, a common outcome in pediatric cases. Dr. Goldstein’s observations suggest that QUELIMMUNE could represent a significant advancement in pediatric critical care, with implications for treating a wider range of conditions in the future.
