SeaStar Medical Announces CMS Coverage for Medicare and Medicaid Eligible Patients with Cardiorenal Syndrome Awaiting LVAD in Investigational Trial of SCD Therapy

Coverage marks SeaStar Medical’s second award by CMS for reimbursement of medical expenses for Medicare and Medicaid patients in a clinical trial Stands out as rare award with less than 100 clinical trials covered annually DENVER, May 28, 2025 (GLOBE NEWSWIRE) -- SeaStar Medical Holding Corporation (Nasdaq: ICU), a commercial-stage healthcare company focused on transforming treatments for critically ill patients facing organ failure and potential loss of life, announced today that the U.S. Centers for Medicare & Medicaid Services (CMS) has agreed to pay for certain expenses incurred by medical centers treating patients covered by Medicare or Medicaid who are enrolled in the NEUTRALIZE-CRS investigational clinical trial. This follows the company’s first award for reimbursement by the CMS that was granted in July 2024 for qualified patients treated in the ongoing NEUTRALIZE-AKI pivotal clinical trial. “To receive CMS coverage of certain expenses for patients in a clinical trial is rare, with less than 100 per year, and we believe reflects the life-saving potential of our technology,” said Eric Schlorff, SeaStar Medical CEO. “We fulfilled multiple criteria set forth by the CMS for this award, including ten study criteria elements that included assessment of how we could improve health outcomes, how generalizable the Selective Cytopheretic Device (SCD) therapy would be to the Medicare population, and how the study results would not duplicate existing knowledge.” Mr. Schlorff continued, "As we initiate our pre-commercialization efforts for our SCD therapy in patients with Acute Kidney Injury (AKI), we recognize that CMS coverage in the commercial setting will be a key element to bringing our potential organ-sparing and life-saving therapies to more patients. We have already engaged a third-party reimbursement policy expert to analyze the feasibility of obtaining reimbursement coverage upon a potential FDA approval for our SCD therapy in adult patients with AKI. Based on the results of the analysis, the high unmet need, and Healthcare Economics and Outcomes Research (HEOR) data supporting reduced healthcare costs, we are building a compelling case that should enable CMS and private payers to understand the value of the SCD therapy in adult patients with AKI." The NEUTRALIZE-AKI pivotal clinical trial and NEUTRALIZE-CRS investigational clinical trial are evaluating the ability of SeaStar Medical’s SCD therapy to neutralize destructive hyperinflammation to improve health outcomes. The SCD therapy is designed as a disease-modifying device that neutralizes over-active immune cells and stops the cytokine storm that yields destructive hyperinflammation and creates a cascade of events that wreak havoc in the patient’s body. The NEUTRALIZE-AKI pivotal trial was granted CMS coverage in July 2024 for qualified patients. The trial is evaluating the safety and efficacy of the SCD therapy in 200 adults with AKI in the ICU receiving CRRT. It is currently 50% enrolled, with full enrollment anticipated near the end of 2025. The trial’s primary endpoint is a composite of 90-day mortality or dialysis dependency of patients treated with the SCD therapy in addition to CRRT as the standard of care, compared with the control group receiving only CRRT standard of care. The FDA has granted Breakthrough Device Designation for the SCD therapy in adult patients with AKI and CRRT. The NEUTRALIZE-CRS trial is designed to evaluate the safety and initial efficacy of the SCD therapy in reducing destructive hyperinflammation in adult patients with acute heart failure with worsening renal function due to cardiorenal syndrome or severe right ventricular failure awaiting a left ventricular assist device (LVAD) implantation. The trial is expected to enroll 20 patients at up to five clinical sites and will be funded by a previously announced $3.6 million National Institutes of Health (NIH) grant awarded to Innovative BioTherapies (IBT), which is led by SCD inventor H. David Humes, MD, Professor, Division of Nephrology, Internal Medicine, University of Michigan and SeaStar Medical Scientific Advisor. Dr. Humes will serve as lead investigator for the study and SeaStar Medical will act as clinical research organization (CRO). The FDA has granted Breakthrough Device Designation for the SCD in cardiorenal syndrome awaiting LVAD implantation. About SeaStar Medical SeaStar Medical is a commercial-stage healthcare company focused on transforming treatments for critically ill patients facing organ failure and potential loss of life. SeaStar’s first commercial product, QUELIMMUNE (SCD-PED), was approved in 2024 by the U.S. Food and Drug Administration (FDA). It is the only FDA approved product for the ultra-rare condition of life-threatening acute kidney injury (AKI) due to sepsis or a septic condition in critically ill pediatric patients. SeaStar’s Selective Cytopheretic Device (SCD) therapy has been awarded Breakthrough Device Designation for six therapeutic indications by the FDA, enabling the potential for a speedier pathway to approval and preferable reimbursement dynamics at commercial launch. The company is currently conducting a pivotal trial of its SCD therapy in adult patients with AKI requiring continuous renal replacement therapy (CRRT), a life-threatening condition with no effective treatment options that impacts over 200,000 adults in the U.S. annually.
