SeaStar Medical Reports 65.1% Survival Rate At Day 90 In Its QUELIMMUNE SAVE Registry Analysis Presented At ASN Kidney Week 2026

SeaStar Medical Holding Corporation (NASDAQ:ICU), a commercial-stage healthcare company focused on transformational treatments for critically ill patients facing organ failure and potential loss of life, announced today new positive data from the late-breaking presentation at ASN Kidney Week 2026 in Denver, Colorado.

The primary exposure-defined analysis at Day 90 resulted in a statistically significant increase in survival of the QUELIMMUNE (SCD-PED) cohort achieving 65.1% survival compared to 47.4% for the KID cohort (P = 0.043), representing more than double the odds of survival for QUELIMMUNE (SCD-PED)-treated patients (odds ratio [OR] 2.07; 95% confidence interval, [CI] 1.04-4.11). The Bayesian probability of higher survival in QUELIMMUNE (SCD-PED) patients was 98.2%. A second landmark sensitivity analysis favored the QUELIMMUNE (SCD-PED) cohort achieving 63.8% Day 90 survival, an increase of 15.1 percentage points over the KID cohort survival of 48.7% (P= 0.074), representing 86% higher estimated odds of survival (OR 1.86; 95% CI, 0.96-3.60). The Bayesian probability of higher survival in the QUELIMMUNE (SCD-PED) landmark cohort was 96.8%.
