NCT ID NCT05439044
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tracked over 4,200 immunocompromised patients who received monoclonal antibodies to prevent or treat severe COVID-19. Researchers measured how many were hospitalized or died from the virus. The goal was to see if these antibody treatments help protect people whose immune systems don't respond well to vaccines.
