Summary
This study follows 160 children and adults with beta-thalassemia or sickle cell disease who received a one-time treatment of their own CRISPR-edited stem cells (CTX001). Researchers will monitor participants for years to check for side effects, new cancers, and how well the therapy controls their disease. The goal is to understand the long-term safety and lasting benefits of this gene-editing approach.
