• Data illustrate the potential of QUELIMMUNE^™️ with cost neutrality starting at 6 days of therapy and a significant reduction in total hospitalization costs in children with acute kidney injury
• SeaStar Medical’s SCD was featured in four Company presentations at the premier nephrology conference

CORRECTION: “Importantly, our findings underscore the opportunity for widespread adoption by hospitals to generate cost savings, while also saving lives”

DENVER, Oct. 25, 2024 (GLOBE NEWSWIRE) -- 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 that for the first time new data highlighting the cost savings of its first-in-class, cell-directed Selective Cytopheretic Device (SCD) Pediatric therapeutic device, QUELIMMUNE, were presented yesterday at the American Society of Nephrology’s (ASN) Kidney Week 2024, underway in San Diego.

“We are thrilled to present a high-quality analysis highlighting the significant potential cost-saving benefits of QUELIMMUNE to the healthcare system in treating critically ill children with acute kidney injury (AKI) at this renowned nephrology conference," said Eric Schlorff, CEO of SeaStar Medical. “QUELIMMUNE is another tool in the arsenal for hospitals to defeat pediatric AKI with sepsis. Sepsis is a big challenge, which is why the Centers for Medicare & Medicaid Services (CMS) developed the SEP-1 protocol and quality metric for hospital systems to perform against.

“Importantly, our findings underscore the opportunity for widespread adoption by hospitals to generate significant cost savings while also saving lives,” he added. “Utilization of QUELIMMUNE is also operationally efficient. It fits directly into existing continual renal replacement therapy (CRRT) circuits.”

The poster, titled Cost Impact of An Immunomodulatory Selective Cytopheretic Device in Pediatrics (SCD-PED) in AKI due to Sepsis (AKI-S), presents an analysis of the Kids’ Inpatient Database (KID) revealing that the hospitalization cost of pediatric patients with AKI requiring CRRT, a majority of whom were septic, was $461,736 per hospitalization, highlighting an exceptionally high financial burden on institutions and the healthcare system. Data from KID and SeaStar Medical’s SCD-PED studies indicate that hospitalization costs were significantly lower for critically ill children with AKI on CRRT who were treated with QUELIMMUNE, a majority of whom were septic, compared with historical average hospital costs for children not treated with QUELIMMUNE. Treatment with QUELIMMUNE results in a projected cost savings of approximately $30,000 per hospitalization principally driven by the lower expected death rate and shorter length of stay versus standard of care.

Additional benefits of QUELIMMUNE included a cost-effective solution for institutions starting at 6 days of QUELIMMUNE therapy, which produced cost neutrality for QUELIMMUNE afforded by the high survival rate of 77% in children ≥10 kg and age ≤22 years with AKI requiring CRRT treated with QUELIMMUNE, versus the control survival rate of approximately 50%. Further, the combined observed outcomes of 0% dialysis dependence at day 60 from the SCD PED-01 and SCD-PED-02 studies illustrate the durability of QUELIMMUNE therapy.  

The SeaStar Medical team has a significant presence at Kidney Week 2024, with a total of four posters being presented by the Company. A second poster describes the mechanistic effects of reducing hyperinflammatory markers in patients with AKI. Additional SeaStar Medical posters that highlight the design of the ongoing NEUTRALIZE-AKI pivotal trial and the upcoming NEUTRALIZE-CRS trial are summarized below:  

• NEUTRALIZE-AKI: A Multicenter, Randomized, Controlled Pivotal Study to Assess the Safety and Efficacy of a Selective Cytopheretic Device in Patients with AKI Requiring Continuous Kidney Replacement Therapy (L. Yessayan, et al.) The ongoing NEUTRALIZE-AKI trial aims to evaluate the safety and efficacy of the SCD in adults with AKI requiring CKRT.
  
  
• NEUTRALIZE-CRS: A Multicenter, Single-Arm, Open-Label Study to Assess a Selective Cytopheretic Device in Bridging Severe Heart Failure Patients to Left Ventricular Assist Device (LVAD) Implantation (L. Yessayan, et al.). This study is designed to evaluate SCD treatment in cardiorenal syndrome (CRS) patients and its effectiveness in bridging them to LVAD. The study aims to enroll 20 ICU patients with acute or chronic systolic heart failure and worsening renal function due to CRS who are awaiting LVAD implantation. Key outcomes include safety of the SCD, reversal of cardiac and renal dysfunction and the number of patients successfully transitioned to LVAD.

ASN Kidney Week

ASN Kidney Week is the world’s premier nephrology meeting with more than 12,000 kidney professionals from across the globe expected to attend the 2024 event. ASN Kidney Week provides participants exciting and challenging opportunities to exchange knowledge, learn the latest scientific and medical advances, and listen to engaging and provocative discussions with leading experts in the field.  

Acute Kidney Injury (AKI) and Hyperinflammation

AKI 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 Device

The 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 has been awarded U.S. Food and Drug Administration (FDA) Breakthrough Therapy Designation in three indications:

• Cardiorenal Syndrome – Left Ventricular Assist Device (CRS-LVAD)
• Adult Acute Kidney Injury (AKI)
• Hepatorenal Syndrome (HRS)

QUELIMMUNE, the SCD-Pediatric device, is being commercialized following 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.
