SeaStar Medical Reports Enrollment Momentum in Its Pivotal Adult AKI Trial

DENVER, Sept. 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 the enrollment of four additional subjects in a 10-day period in its pivotal NEUTRALIZE-AKI trial, bringing total trial enrollment to 46. This trial is evaluating the safety and efficacy of SeaStar Medical's proprietary therapeutic Selective Cytopheretic Device (SCD) in adults with acute kidney injury (AKI) in the intensive care unit (ICU) receiving continuous kidney replacement therapy (CKRT).

"We are encouraged to see a recent uptick in enrollment following a slow summer period due to low census across many of the ICUs participating in this trial," said Kevin Chung, MD, Chief Medical Officer of SeaStar Medical. "Finishing this pivotal trial is a major priority for our company and will bring us one step closer to commercialization of what we believe is a practice-changing therapy in critically ill adults. Our next major step is an interim analysis at the halfway point, which will help inform our Data and Safety Monitoring Board (DSMB) that can recommend concluding the study early if statistical significance is reached. Regardless, we are working to expand the number of trial sites by more than a dozen to accelerate towards our original goal of enrolling 200 subjects as quickly as possible."

NEUTRALIZE-AKI Pivotal Trial

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

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-Pediatric device, brand named QUELIMMUNE^™, is being commercialized following earning 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.

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.
