Recent history shows sharp negative reactions to corporate and financing-related events (reverse split, CFO appointment, earnings), while clearly positive regulatory news, such as FDA actions around QUELIMMUNE, drew favorable responses.
Over the last few months, ICU navigated capital markets actions and early commercialization. A 1-for-10 reverse split and proxy filings addressed Nasdaq bid-price compliance, while at-the-market offerings supplemented cash. Operationally, QUELIMMUNE gained FDA support via reduced SAVE registry enrollment and showed encouraging survival data, and a new CFO with public-market experience joined. The current 2026 milestone update builds on these steps, focusing on expanding pediatric AKI adoption and advancing pivotal trials in adult AKI and cardiorenal indications.
Market Pulse Summary
This announcement outlines SeaStar Medical’s 2026 focus on scaling QUELIMMUNE in pediatric AKI, targeting about $2 million in net product revenue and adding 15 leading centers. It also emphasizes progressing the 339-patient NEUTRALIZE-AKI pivotal trial and initiating pivotal work in CHF with cardiorenal syndrome. Investors may watch enrollment pace, real‑world survival outcomes, and regulatory interactions, alongside the company’s ability to fund these programs given its small market capitalization.

Drive adoption of QUELIMMUNE for ultra-rare pediatric AKI, expanding revenue and doubling the customer base
Advance SeaStar Medical’s first-in-class SCD therapy for the adult AKI indication – a potential
Progress the clinical development of the SCD therapy in patients with severe heart failure
Leverage rapid pathways to commercialization of the SCD therapy through additional FDA Humanitarian Use and Breakthrough Device Designations
DENVER, Jan. 07, 2026 (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 its key milestones for 2026.
“Our first full year as a commercial company provided a clear demonstration that the Selective Cytopheretic Device (SCD) therapy can save lives and spare organ function, with major pediatric medical institutions, such as Cincinnati Children’s Hospital, Stanford Medical Center, UCSF Benioff Children’s Hospitals, and University of Michigan, adopting the therapy and reporting their findings,” said Eric Schlorff, CEO of SeaStar Medical. “Beyond the pediatric acute kidney injury (AKI) patient population, there are hundreds of thousands of patients that experience the life-threatening consequences of uncontrolled destructive hyperinflammation with no viable treatment options today. We are already evaluating the potential broad applicability of our SCD therapy in adult patients with AKI and also in patients with chronic heart failure (CHF) awaiting a left ventricular assist device (LVAD) implantation. These indications represent a potential multi-billion-dollar market opportunity in the U.S. alone. The ability to expand the SCD therapy to additional indications and therapeutic areas could extend this opportunity even further.”
Mr. Schlorff continued, “We believe 2026 will be a major pivot point for the company. With continued adoption of the QUELIMMUNE therapy, we believe we can save more children’s lives and spare damage to their organs. We also plan to accelerate enrollment in our NEUTRALIZE-AKI pivotal trial to complete enrollment near the end of 2026. Provided a successful outcome of the trial, we will submit our Premarket Approval application (PMA) in 2027 in hopes of a rapid approval and strong early adoption, given our established commercial infrastructure.”
Key 2026 milestones for SeaStar Medical include the following:
- Broaden QUELIMMUNE adoption to include 15 additional top-ranked children’s medical centers, more than doubling the total number of sites and building increased depth in customer orders. SeaStar Medical anticipates achieving approximately
$2 million in net product revenue in 2026. - Advance the SCD therapy for the adult AKI indication through completion of enrollment in the NEUTRALIZE-AKI pivotal trial near the end of 2026 and initiation of a modular PMA process. SeaStar Medical has been granted Breakthrough Device Designation by the FDA for this indication, which is designed to expedite the PMA approval process for novel devices that will save lives and treat debilitating diseases. The modular PMA process may also speed the review and approval process.
- Evaluate broader applicability of the SCD therapy through the conduct of a pivotal trial of the SCD therapy in patients with acute CHF with cardiorenal syndrome (CRS) awaiting LVAD implantation. SeaStar Medical has also been granted Breakthrough Device Designation by the FDA for this indication given the severity of the disease and lack of current effective treatments.
- Explore rapid regulatory pathways to commercialization of the SCD therapy as a first-in-class therapy, designed to save lives and spare organ function in numerous destructive hyperinflammatory conditions. SeaStar Medical will seek additional Humanitarian Use and Breakthrough Device Designations to potentially provide lifesaving support to these patients as rapidly as possible.
SeaStar Medical’s 2026 milestones are built on the foundation of achievements from 2025 including:
- Expanded the QUELIMMUNE customer base to 10 customers from top-rated children’s hospitals, building increased depth in the number of customers ordering QUELIMMUNE. This ultra-rare pediatric AKI market represents SeaStar Medical’s first approved product that employs its SCD technology. Product line extensions represent significantly larger market opportunities.
- Presented real-world pediatric patient survival data from the commercial use of the QUELIMMUNE therapy that showed no device related safety events with the QUELIMMUNE therapy, with
76% of patients surviving through 60 days and71% surviving through 90 days. These new data from the SAVE Surveillance Registry of 21 critically ill pediatric patients with life-threatening AKI and sepsis or a septic condition were presented at the 5th International Symposium on Acute Kidney Injury in Children. These results are on track to validate a nearly50% reduction in loss of life compared to historical data, as reported previously in Kidney Medicine. - Announced a successful interim analysis of the NEUTRALIZE-AKI trial by the independent Data Safety Monitoring Review Board (DSMB), providing a positive signal toward efficacy and zero device-related safety issues. This pivotal clinical trial is designed to evaluate the safety and efficacy of the SCD therapy in 339 adults with AKI in the ICU receiving continuous renal replacement therapy (CRRT).
- Initiated the NEUTRALIZE-CRS clinical trial to treat patients with acute CHF with cardiorenal syndrome (CRS) awaiting LVAD implantation. The trial is expected to enroll 20 patients in the ICU setting with CHF and CRS who are ineligible for LVAD or heart transplantation.
About QUELIMMUNE
The QUELIMMUNE (SCD-PED) therapy is SeaStar Medical’s first commercial product based on its patented Selective Cytopheretic Device (SCD) technology. The QUELIMMUNE™ therapy is being commercialized for children (age 22 or younger) with AKI and sepsis or a septic condition weighing 10 kilograms or more who are on antibiotics and being treated in the ICU with Renal Replacement Therapy (RRT). It was approved in February 2024 under a Humanitarian Device Exemption application that requires medical institutions to also participate in the SAVE Surveillance Registry and complete Institutional Review Board approvals prior to adoption and use of the QUELIMMUNE therapy. This prolongs the adoption timeline by medical institutions but provides important data on the use of QUELIMMUNE in the “real-world” setting.
Data from two clinical studies of the QUELIMMUNE therapy, published in Kidney Medicine, showed a
In January 2025, SeaStar Medical was awarded the 2025 Corporate Innovator Award by the National Kidney Foundation for its significant contribution to improving the lives of pediatric patients with AKI based on the approval and introduction of the QUELIMMUNE therapy.
About 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 evaluating the safety and efficacy of the SCD therapy in 339 adults with AKI in the ICU receiving CRRT. 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. 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 the SCD therapy in AKI patients with sepsis and acute respiratory distress syndrome.
About 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 sepsis, severe trauma, surgery and COVID-19. AKI can cause destructive hyperinflammation, which is the overproduction or overactivity of inflammatory effector cells and other molecules that can be toxic. Damage resulting from this destructive 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 complications including chronic kidney disease or end-stage renal disease (ESRD) requiring dialysis. Extreme hyperinflammation may also contribute to added healthcare costs, such as prolonged ICU stays and increased reliance on dialysis and mechanical ventilation.
About the SeaStar Medical Selective Cytopheretic Device (SCD) Therapy
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 SCD therapy is designed for broad applications in multiple acute and chronic kidney and cardiovascular diseases, representing patients who today have no FDA-approved options for treating their disease. Unlike pathogen removal and other blood-purification tools, the SCD therapy is integrated with an existing continuous renal replacement therapy (CRRT) hemofiltration system 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, eliminate the need for future CRRT, including dialysis, and prevent loss of life.
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. The QUELIMMUNE (SCD-PED) therapy is SeaStar Medical’s first commercial product based on its patented Selective Cytopheretic Device (SCD) technology. The QUELIMMUNE (SCD-PED) therapy 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 Medical’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 the NEUTRALIZE-AKI pivotal clinical 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.
