Brief Summary:
This is an open label, multi-center study to evaluate the safety and Efficacy of ET-01 Transplantation in subjects with Transfusion Dependent β-Thalassaemia.

Condition or disease Intervention/treatment Phase
Transfusion Dependent Beta-Thalassaemia Biological: ET-01 Not Applicable

Detailed Description:
After the proper subject is recruited, subject will go through steps generally as stem cell mobilization, apheresis, conditioning and ET-01 infusion to complete therapy. Two years follow-up will be carried out post-transplantation and related data will be collected. Subjects who have been treated by ET-01 will be asked to participate in a long-term follow up study. Monitoring the long-term efficacy and safety up to 15 years after ET-01 transplant.
