SeaStar Medical Holding Corporation announces that the National Institutes of Health’s (NIH) National Heart, Lung, and Blood Institute has awarded a $3.6 million grant for a clinical trial to evaluate the Selective Cytopheretic Device Adult (SCD-ADULT.
DENVER, April 30, 2024 (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 that the National Institutes of Health’s (NIH) National Heart, Lung, and Blood Institute has awarded a $3.6 million grant for a clinical trial to evaluate the Selective Cytopheretic Device Adult (SCD-ADULT, a member of the Company’s Quelimmune™ product family) as a bridging strategy to left ventricular assist device (LVAD) implantation in patients with chronic heart failure (CHF) who have progressed to acute decompensated heart failure (ADHF). This grant award follows a Breakthrough Device Designation for cardiorenal syndrome granted by the U.S. Food and Drug Administration (FDA’s) Center for Biologics Evaluation and Research (CBER) in September 2023.
With current standard of care treatment, ADHF can accelerate worsening renal function in a feedback loop known as cardiorenal syndrome, which is associated with a poor prognosis. These patients are often ineligible for lifesaving LVAD implantation due to the severity of their condition.
This grant was awarded to Innovative BioTherapies (IBT), which is led by SCD inventor H. David Humes, M.D., Professor, Division of Nephrology, Internal Medicine, University of Michigan and SeaStar Medical Scientific Advisor. SeaStar Medical is expected to directly receive approximately one-quarter of the grant for serving as the contract research organization for the trial, which can be leveraged for other indications. The trial is expected to enroll 20 ICU patients with ADHF at four sites who are ineligible for LVAD or cardiac transplantation in order to determine whether the SCD-ADULT can improve these patients’ condition such that they are able to bridge to LVAD implantation. If successful, this study could pave the way for a marketing application to FDA.
In February 2024, SeaStar Medical announced publication of a manuscript titled “New opportunity for targeting systemic inflammation in patients with heart failure through leucocyte immunomodulation” in the peer-reviewed European Journal of Heart Failure (Pitt, B., Iyer, S.P.N. and Humes, H.D.). The manuscript reviews the role of chronic dysregulated systemic inflammation in heart failure and the potential application of SCD-ADULT in enabling previously ineligible patients with severe disease to receive an LVAD or heart transplant. The NIH grant is based upon the first-in-human case study discussed in the manuscript, as well as improved cardiac contractility in a canine model of CHF following treatment with the SCD. Those results were published in the peer-reviewed journal PLOS One in April 2023, and also served as the basis for SeaStar Medical’s Breakthrough Device Designation for cardiorenal syndrome.
“Several other therapeutic agents tested in large prospective trials of patients with ADHF have demonstrated no clinically relevant efficacy outcomes and often had unacceptable adverse events,” said Dr. Humes. “In contrast, SCD therapy, which immunomodulates activated circulating leukocytes, represents a novel approach to treating cardiorenal syndrome that could address the critical limitation of other therapeutic strategies tested to date.”
“This grant will fund a single clinical trial that could support FDA approval of SCD-ADULT for ADHF,” said Eric Schlorff, SeaStar Medical CEO. “We are encouraged by the NIH’s support and appreciate Dr. Humes and his team’s oversight of this trial while we pursue the SCD-ADULT’s approval in adult acute kidney injury and evaluate additional applications in high-value, unmet medical needs where hyperinflammation plays a role.”
On February 22, 2024, SeaStar Medical announced the Humanitarian Device Exemption (HDE) FDA Approval Order for Quelimmune for use in children weighing 10 kilograms or more with acute kidney injury due to sepsis or a septic condition requiring kidney replacement therapy (KRT). SeaStar Medical also has an ongoing pivotal study evaluating treatment with the SCD in adults in the ICU with acute kidney injury.
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
The Selective Cytopheretic Device (SCD) is a patented cell-directed extracorporeal device that employs immunomodulating technology to selectively target proinflammatory neutrophils and monocytes during continuous KRT (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. The SCD 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. At this time Quelimmune is specifically branded for pediatric acute kidney injury (AKI).
About Innovative BioTherapies
IBT is a privately held biotechnology company founded to facilitate the commercialization of technology developed in Dr. H. David Humes’ academic laboratory. IBT’s research and development program is primarily supported by federal grants and contracts that focus on developing cell therapy devices utilizing human progenitor cells, biomimetic materials, and micro-electromechanical systems (MEMs) technology.

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.
