SeaStar Medical Announces Activation of First Clinical Site in Pivotal Trial with Selective Cytopheretic Device in Critically Ill Adults with Acute Kidney Injury

DENVER, April 19, 2023 (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 the activation of Good Samaritan Regional Medical Center in Corvallis, Oregon, as the first clinical site in its pivotal NEUTRALIZE-AKI trial. This trial, expected to include up to 30 U.S. sites, is evaluating the safety and efficacy of SeaStar Medical’s patented, first-in-class, cell-directed Selective Cytopheretic Device (SCD) extracorporeal therapy in critically ill adults with acute kidney injury (AKI) requiring continuous kidney replacement therapy (CKRT).

“We recently received FDA approval to begin this pivotal trial and activated the first clinical site in record time, with many more sites expected to come onboard in the near term,” said Kevin Chung, MD, Chief Medical Officer of SeaStar Medical. “Previous clinical studies with the SCD have demonstrated reduced mortality and dialysis dependency in these critically ill patients, and we look forward to rapid enrollment of eligible patients into the NEUTRALIZE-AKI trial to validate these results.”

“We are honored to be the first clinical site activated in the NEUTRALIZE-AKI clinical study and are eager to evaluate the SCD therapy’s potential to improve outcomes for these critically ill patients,” said Brian Delmonaco, MD, FACEP, Medical Director of Samaritan Health Services Pulmonology and Critical Care Medicine and the principal investigator for Good Samaritan Regional Medical Center.

Four non-COVID completed studies evaluating the safety and feasibility of the SCD in adults and pediatric patients with AKI requiring CKRT showed Day 60 reductions in mortality of up to 50% and no dialysis dependency, compared with 15% to 25% dialysis dependency in historical controls.

The NEUTRALIZE-AKI (NEUTRophil and monocyte deActivation via SeLective CytopheretIic Device - a randomiZEd clinical trial in Acute Kidney Injury) pivotal trial is expected to enroll up to 200 patients. 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.

An estimated six million American adults and children are diagnosed with AKI each year, and more than 200,000 require CKRT as part of their care. In 2022 the SCD received FDA Breakthrough Device Designation for adult use. This designation is awarded to a therapy to treat a serious or life-threatening condition with preliminary clinical evidence indicating the therapy may demonstrate substantial improvement on clinically significant endpoints over available therapies. Breakthrough therapies receive many benefits, including a commitment by the FDA to expedite development and review.

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. Unlike pathogen removal and other blood-purification tools, the SCD selectively targets the most highly activated proinflammatory neutrophils and monocytes. The Company has observed that these most highly activated immune cells are turned off in a low calcium environment. The SCD therapy mimics nature by creating a unique micro-environment, attracting these highly activated effector cells and neutralizing them in such an environment. These cells are then returned back into the body through the blood, and the body is signaled to focus on repair.

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.
