Brief Summary:
This is an open label, single site 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 proper subject is recruited, subject will go through steps generally as stem cell mobilization, apheresis, conditioning and ET-01 infusion to complete therapy. 2 years' follow up visits will be carried out post-transplantation and related data will be collected.

Primary Outcome Measures :
  1. Frequency and severity of AEs & SAEs identified according to NCI CTCAE 5.0. [ Time Frame: from ET-01 infusion to 104 weeks post-transplant ]
  2. Incidence of abnormal laboratory test results after transplant [ Time Frame: from ET-01 infusion to 104 weeks post-transplant ]
  3. Incidence of abnormal vital signs after transplant [ Time Frame: from ET-01 infusion to 104 weeks post-transplant ]
  4. Incidence of clinical significant abnormal vital signs. [ Time Frame: from ET-01 infusion to 60mins after ET-01 infusion ]
  5. Proportion of subjects with clinical significant abnormal vital signs. [ Time Frame: from ET-01 infusion to 60mins after ET-01 infusion ]
  6. Mortality after ET-01 infusion. [ Time Frame: within 100 days post-transplant ]

Secondary Outcome Measures :
  1. Engraftment of ET-01 in subjects. [ Time Frame: within 42 days post-transplant ]
    neutrophil count [ANC] >500 /mm3 for 3 consecutive days or platelet count [PLT] >20000/mm3 for 7 consecutive days

  2. Change in total hemoglobin from baseline. [ Time Frame: within 104 weeks post-transplant ]
  3. Change in HbF from baseline. [ Time Frame: within 104 weeks post-transplant ]
  4. Change in HbA from baseline. [ Time Frame: within 104 weeks post-transplant ]
  5. Change in proportion of HbF/HbA. [ Time Frame: within 104 weeks post-transplant ]
  6. Change in frequency of packed RBC transfusions. [ Time Frame: from 6 months before recruitment to 104 weeks post-transplant ]
  7. Change in volume of packed RBC transfusions. [ Time Frame: from 6 months before recruitment to 104 weeks post-transplant ]
