New stem cell therapy aims to free patients from lifelong blood transfusions
NCT ID NCT04390971
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new treatment called ET-01 in 3 people with transfusion-dependent beta-thalassemia, a blood disorder that requires regular blood transfusions. The treatment uses the patient's own stem cells, which are modified and then transplanted back. The goal was to see if it is safe and can reduce or eliminate the need for transfusions by helping the body produce healthy red blood cells.
