Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
What this trial is testing
The companion study to the sickle cell trial, in people with beta thalassemia who needed regular blood transfusions to live. The question was whether editing their own stem cells would let them stop. Most participants became transfusion-independent.
An open-label, single-arm Phase 2/3 study of exagamglogene autotemcel in patients aged 12–35 with transfusion-dependent beta thalassemia. The primary endpoint was transfusion independence, defined as maintaining a weighted average haemoglobin of at least 9 g/dL without transfusion for at least 12 consecutive months.

What a trial result does and does not mean
Early-phase results come from small numbers of participants and short follow-up. They can change with more people and more time, and a trial that is recruiting, active or even completed has not established that a treatment works. Enrolment criteria are strict; eligibility is decided by the trial site, never by a website.
