ICU SeaStar Medical Holding Corporation

SeaStar Medical Holding Corporation (Nasdaq: ICU), a commercial-stage medical device company developing proprietary solutions to reduce the consequences of hyperinflammation on vital organs, announces the activation of Brooke Army Medical Center (BAMC) and the United States Army Institute of Surgical Research (USAISR), expanding the number of sites in its NEUTRALIZE-AKI pivotal trial. This trial is evaluating the safety and efficacy of SeaStar Medical’s innovative Selective Cytopheretic Device (SCD) in treating acute kidney injury (AKI) in adult ICU patients receiving continuous kidney replacement therapy (CKRT). With the inclusion of these prestigious military medical facilities, SeaStar Medical now has 11 active clinical sites with 48 subjects enrolled to date.

The SCD has received U.S. Food and Drug Administration (FDA) Breakthrough Device Designation for adults with AKI, which is awarded to the SCD as a therapy to treat a serious or life-threatening condition with preliminary clinical evidence indicating it may demonstrate substantial improvement over available therapies on clinically significant endpoints. In July 2024, the U.S. Centers for Medicare and Medicaid (CMS) granted Category B coverage for certain expenses incurred by medical centers treating Medicare and Medicaid patients enrolled in the NEUTRALIZE-AKI pivotal trial.

“We are delighted that these premier Department of Defense (DoD) facilities have joined our adult AKI trial,” said Kevin Chung, MD, Chief Medical Officer of SeaStar Medical. “BAMC and USAISR are where the most critically ill patients from the DoD and the south Texas region are treated. Having these two sites on board will help us achieve our goal of making this disease-modifying therapy available for all critically ill patients with AKI, regardless of the type of hospital.”

Among other accomplishments, SeaStar Medical began shipping the SCD Pediatric, brand named QUELIMMUNE™, for pediatric patients with AKI and sepsis indications in July 2024, having received Humanitarian Device Exemption (HDE) approval from the FDA earlier in 2024. Additionally, the Company paid-off all interest-bearing debt in September 2024.

NEUTRALIZE-AKI Pivotal TrialThe NEUTRALIZE-AKI (NEUTRophil and monocyte deActivation via SeLective Cytopheretic Device – a randomIZEd clinical trial in Acute Kidney Injury) pivotal trial is expected to enroll up to 200 adults. The trial’s primary endpoint is a composite of 90-day mortality or dialysis dependency of patients treated with SCD in addition to CKRT as the standard of care, compared with the control group receiving only CKRT standard of care. Secondary endpoints include mortality at 28 days, ICU-free days in the first 28 days, major adverse kidney events at Day 90 and dialysis dependency at one year. The study will also include subgroup analyses to explore the effectiveness of SCD therapy in AKI patients with sepsis and acute respiratory distress syndrome.

Acute Kidney Injury (AKI) and HyperinflammationAKI is characterized by a sudden and temporary loss of kidney function and can be caused by a variety of conditions such as COVID-19, sepsis, severe trauma and surgery. AKI can cause hyperinflammation, which is the overproduction or overactivity of inflammatory effector cells and other molecules that can be toxic. Damage resulting from hyperinflammation in AKI can progress to other organs, such as the heart or liver, and potentially to multi-organ dysfunction or even failure that could result in worse outcomes, including increased risk of death. Even after resolution, these patients may face chronic kidney disease or end-stage renal disease requiring dialysis, among other complications. Hyperinflammation may also contribute to added healthcare costs, such as prolonged ICU stays and increased reliance on dialysis and mechanical ventilation.

Selective Cytopheretic DeviceThe Selective Cytopheretic Device (SCD) is a patented cell-directed extracorporeal device that employs immunomodulating technology to selectively target proinflammatory neutrophils and monocytes during CKRT and reduces the hyperinflammatory milieu including the cytokine storm. Unlike pathogen removal and other blood-purification tools, the SCD 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. This unique immunomodulation approach may promote long-term organ recovery and eliminate the need for future KRT, including dialysis.

The SCD-Pediatric device, brand named QUELIMMUNE™, is being commercialized following earning FDA approval for children with AKI and sepsis or septic condition weighing 10 kilograms or more who are being treated in the ICU with KRT. QUELIMMUNE was approved in February 2024 under a Humanitarian Device Exemption (HDE) application, having met the applicable criteria with clinical results showing safety and probable clinical benefit in a limited population of critically ill children with AKI who have few treatment options.

About SeaStar MedicalSeaStar Medical is a commercial-stage 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.
