• U.S. total addressable market for five initial indications is $25 to $33 billion
• REMINDER: Business Update Conference Call begins at 4:30 p.m. Eastern time today

DENVER , Dec. 11, 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, estimates a U.S. total addressable market for its proprietary, patented Selective Cytopheretic Device (SCD) in five clinical indications, subject to U.S. Food & Drug Administration (FDA) approvals, of $25 to $33 billion.

The following chart summarizes ranges of the adult SCD total addressable market and estimated clinical trial costs, by indication:

“The estimated size of these U.S. markets versus our projected clinical trial costs clearly warrant pursuing FDA approvals in these indications. The ability to use the SCD as currently configured, without alteration for each new indication, allows us to cost-efficiently approach the total addressable market. Additionally, we expect future commercial sales for the SCD in adult AKI to help cover clinical trial costs,” said Eric Schlorff, SeaStar Medical CEO. “We have already reached a major regulatory milestone in securing approval for the SCD-Pediatric, branded as QUELIMMUNE^™, for treating critically ill children with AKI and sepsis. It is highly unusual for a company to gain approval in a pediatric indication before the adult indication, which we believe provides support for future SCD regulatory approvals.”

The SCD has been awarded FDA Breakthrough Device Designation (BDD) in three of the five indications included in the chart above, namely adult AKI, hepatorenal syndrome and cardiorenal syndrome with LVAD. The SCD was also awarded BDD for chronic dialysis in November 2024. The BDD designation holds numerous benefits including enhanced access to FDA resources resulting in faster development, as well as priority review by the FDA, early access to patients and the potential for differentiated market positioning. The company recently submitted a clinical trial protocol for chronic dialysis to the FDA for review. Feedback from the FDA will provide SeaStar Medical with the information necessary to appropriately estimate the clinical costs and market size for this indication.

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 renal replacement therapy (CRRT) and reduces the hyperinflammatory milieu including the cytokine storm. Unlike pathogen removal and other blood-purification tools, the SCD is integrated with CRRT 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 renal replacement therapy (RRT), including dialysis.

The SCD-Pediatric device, QUELIMMUNE, 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 RRT. 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.

ADULT Acute Kidney Injury Pivotal Trial

The NEUTRALIZE-AKI (NEUTRophil and monocyte deActivation via SeLective Cytopheretic Device – a randomIZEd clinical trial in Acute Kidney Injury) is expected to enroll up to 200 adults with 69 subjects enrolled to date. The trial’s primary endpoint is a composite of 90-day mortality or dialysis dependency among patients treated with SCD in addition to CRRT as the standard of care, compared with the control group receiving only CRRT 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.
