SeaStar Medical Rises on FDA Enrollment Reduction
SeaStar Medical Holding Corp's stock increased by 5.10% as it crossed above the 5-day SMA. This rise follows the FDA's decision to reduce the mandatory enrollment size for the SAVE Surveillance Registry from 300 to 50 patients, indicating confidence in the safety of QUELIMMUNE therapy.
The reduction in patient enrollment is expected to accelerate the market adoption of QUELIMMUNE therapy, which has shown promising survival rates in preliminary results. Among the first 21 patients, the therapy reported zero device-related adverse events and a 70% survival rate at 90 days, providing hope for pediatric patients suffering from acute kidney injury.
This development not only enhances SeaStar Medical's revenue potential by facilitating smoother adoption of QUELIMMUNE therapy but also positions the company to capture a share of the estimated $100 million pediatric acute kidney injury market in the U.S.
