本试验正在测试什么
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.

试验结果意味着什么，又不意味着什么
早期试验结果来自少量参与者和较短的随访周期，随着人数增加和时间延长，结论可能发生变化。正在招募、进行中甚至已完成的试验，并不代表某种疗法已被证实有效。入组标准十分严格，是否符合条件由试验机构决定，而非由网站判断。
