SeaStar Medical (Nasdaq: ICU) has expanded its customer base by shipping QUELIMMUNE™ to a fifth hospital, a California medical center known for pediatric research. QUELIMMUNE, their Selective Cytopheretic Device (SCD), treats critically ill children in ICU with acute kidney injury (AKI) and sepsis.
The company is actively pursuing additional hospital clearances through institutional review board (IRB) approvals, with more than a dozen new medical centers in discussion and seven advancing in the IRB process. Several existing customers have already placed reorders in 2025.
QUELIMMUNE operates under FDA approval through a Humanitarian Device Exemption for children weighing 10kg or more requiring renal replacement therapy. The device uniquely targets proinflammatory neutrophils and monocytes during continuous renal replacement therapy, potentially promoting long-term organ recovery and eliminating future dialysis needs. The SCD has received FDA Breakthrough Device Designation in four indications.
SeaStar Medical (Nasdaq: ICU) has activated its 15th site, Mayo Clinic, for the NEUTRALIZE-AKI pivotal trial, which is evaluating the safety and efficacy of its Selective Cytopheretic Device (SCD) in treating acute kidney injury (AKI). The trial has currently enrolled 76 subjects, with 6 new enrollments since the start of 2024.
The study aims to evaluate 200 adults with AKI in ICU receiving continuous renal replacement therapy (CRRT). The primary endpoint focuses on 90-day mortality or dialysis dependency compared to standard CRRT care. The company expects a Data Safety Monitoring Board recommendation on interim results by mid-2025 after analyzing the first 100 subjects.
The SCD, which has FDA Breakthrough Device Designation for adults with AKI, targets proinflammatory neutrophils and monocytes during CRRT to reduce hyperinflammation. SeaStar Medical estimates the annual U.S. market opportunity for SCD in adult AKI at $4.7-6.3 billion.
SeaStar Medical (Nasdaq: ICU) received FDA approval for an investigational device exemption (IDE) to study their Selective Cytopheretic Device (SCD-ADULT) in reducing inflammation in adult patients with acute heart failure and worsening renal function. The feasibility study will enroll 20 patients across up to five clinical sites, funded by a $3.6 million NIH grant awarded to Innovative BioTherapies.
The study will be led by SCD inventor Dr. H. David Humes, with SeaStar Medical acting as clinical research organization. The device received Breakthrough Device Designation from FDA's CBER in September 2023 for cardiorenal syndrome with LVAD. The company estimates the total addressable U.S. market for SCD-ADULT in cardiorenal syndrome at over $1 billion annually.
SeaStar Medical (Nasdaq: ICU) has expanded its commercial reach by shipping its QUELIMMUNE™ device to a fourth hospital customer, a prominent academic medical center. QUELIMMUNE is a Selective Cytopheretic Device (SCD) designed to treat critically ill children in ICU with acute kidney injury (AKI) and sepsis.
The device, approved by FDA under Humanitarian Device Exemption, has shown clinical benefits in reducing mortality and decreasing dialysis dependency. According to company data, AKI patients treated with SCD showed no dialysis dependency 60 days post-treatment, potentially saving approximately $100,000 per patient annually in dialysis costs. The average hospital cost per pediatric ICU patient with AKI requiring continuous renal replacement therapy exceeds $350,000.
QUELIMMUNE is approved for children weighing 10 kilograms or more who require renal replacement therapy. The SCD technology uniquely targets proinflammatory neutrophils and monocytes during continuous renal replacement therapy, potentially promoting long-term organ recovery.
SeaStar Medical (Nasdaq: ICU) has activated its 14th hospital site for the NEUTRALIZE-AKI pivotal trial, evaluating their Selective Cytopheretic Device (SCD) in acute kidney injury patients. Currently, 70 of 200 planned subjects are enrolled, with 24 in Q4. The company expects Data Safety Monitoring Board interim results by mid-2025 after the first 100 subjects complete the 90-day primary endpoint.
The company estimates the U.S. addressable market for SCD in adult AKI at $4.7-6.3 billion, with trial costs around $15 million. The SCD has FDA Breakthrough Device Designation for adults with AKI, and received Category B coverage from CMS for certain expenses in July 2024. The trial's primary endpoint focuses on 90-day mortality or dialysis dependency comparing SCD plus CRRT versus CRRT alone.
