Summary

This study tested a gene therapy called SB-525 in 13 adults with severe hemophilia A. The goal was to see if a single infusion could help their bodies produce the missing clotting factor, reducing or eliminating the need for regular factor injections. Participants were followed for up to 5 years to check safety and how long the effect lasted.
