Summary

This study was designed to see how long specially treated red blood cells survive in adults with sickle cell disease who receive regular blood exchange therapy. It was withdrawn before any participants were enrolled, so no results are available. The goal was to better understand the lifespan of these cells to improve future transfusions.
