SeaStar Medical Adds Second Hospital Customer for QUELIMMUNE

DENVER, Oct. 31, 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, has shipped QUELIMMUNE™ directly to a second hospital customer. QUELIMMUNE is the Company’s Selective Cytopheretic Device (SCD) for treating critically ill children in the intensive care unit (ICU) with acute kidney injury (AKI) and sepsis. QUELIMMUNE was granted U.S. Food and Drug Administration (FDA) approval under a Humanitarian Device Exemption (HDE).

“We are excited to add a second hospital customer, which is our first since we transitioned to a direct sales model earlier this month. Under this new model, SeaStar Medical recognizes 100% of revenue generated from commercial sales of QUELIMMUNE,” said Tim Varacek, SeaStar Medical Senior Vice President, Commercial & Business Operations. “Our team worked seamlessly with our customer to ship QUELIMMUNE directly to this hospital. We have capacity to add additional new customers under HUD requirements and fulfill their orders. Our team is working diligently to secure additional HUD clearances with the institutional review boards (IRBs) of various hospitals where we have established relationships and have received in-bound inquiries.”

“The health care economic data we presented at last week’s ASN Kidney Week conference highlights a compelling opportunity for widespread adoption of QUELIMMUNE by hospitals to reduce costs while providing access to our potentially lifesaving therapeutic device to very sick children,” said Eric Schlorff, SeaStar Medical CEO. “Our goal is to have QUELIMMUNE commercially available in the ICUs of four to five leading pediatric hospitals by the end of 2024.”

QUELIMMUNE

QUELIMMUNE is SeaStar Medicals’ Selective Cytopheretic Device (SCD-PED) approved for the treatment of patients weighing 10 kilograms or more with AKI and sepsis or a septic condition on antibiotic therapy and requiring renal replacement therapy (CRRT). A poster presentation at ASN Kidney Week 2024 showed data from the Kids’ Inpatient Database indicating that the cost of treating pediatric patients with AKI on CRRT, a majority of whom were septic, was more than $460,000 per hospitalization. An analysis based on the Company’s SCD-PED studies of critically ill children on CRRT treated with QUELIMMUNE showed a projected cost savings of approximately $30,000 per hospitalization, principally driven by the lower expected death rate and shorter length of hospital stay versus standard of care.

QUELIMMUNE consists of an SCD-PED cartridge and blood tubing set that are connected in-line to an existing hemodialysis delivery system’s extracorporeal CRRT circuit in a process that takes about 15 minutes. The Company expects that, on average, a full course of treatment for children with AKI will require three to seven days, with the disposable SCD-PED cartridge being replaced every 24 hours.

As a HUD device, QUELIMMUNE is required to gain IRB approval from each hospital prior to a commercial sale, with IRBs signing off on the protocol for using the device within their facility, as well as additional hospital clearances, training of critical care teams on integrating the QUELIMMUNE device into existing hemodialysis equipment and a patient registry.

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 (SCD)

QUELIMMUNE is the brand name of the SeaStar Medical’s SCD-PED. It was approved in February 2024 under an HDE application, having met the applicable criteria with clinical results showing safety and probable clinical benefit in a limited patient population who have few treatment options. The SCD is a patented cell-directed extracorporeal device that employs immunomodulating technology to selectively target proinflammatory neutrophils and monocytes during CRRT. 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 RRT, including dialysis.

SeaStar Medical is conducting the NEUTRALIZE-AKI pivotal trial to evaluate the safety and effectiveness of the SCD in the larger patient population of adults with AKI in the ICU receiving CRRT. The SCD-ADULT device has received FDA Breakthrough Device Designation for this indication, which is awarded to 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. The Company is exploring the SCD’s application across a range of acute and chronic indications involving dysregulated immune processes where proinflammatory activated neutrophils and monocytes may contribute to disease progression or severity.

About SeaStar Medical

SeaStar 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.
