Brief Summary:
This is a single center, single arm, open-label study to determine the safety and efficacy of β-globin restored autologous hematopoietic stem cells in β-thalassemia major patients with CVS-654 mutation.

Condition or disease Intervention/treatment Phase
Thalassemia Major Biological: β-globin restored autologous HSC Not Applicable

Detailed Description:
β-globin restored autologous hematopoietic stem cells will be manufactured using Crispr/Cas9 gene editing system. Subject participation for this study will be 1 year. Subjects who enroll in this study will be asked to participate in a subsequent long-term follow up study that will monitor the safety and efficacy of the treatment they receive for up to 15 years post-transplant.

Primary Outcome Measures :
  1. Incidence and Severity of Adverse Events as a Measure of Safety and Tolerability Adverse events assessed according to NCI-CTCAE v4.03 criteria [ Time Frame: up to 6 months post transplant ]

Secondary Outcome Measures :
  1. efficacy of β-globin restored autologous hematopoietic stem cells [ Time Frame: 12 months post transplant ]
    Independence on blood transfusion post transplant; Or, The amount of red cell transfusion in a year post transplant reduced 50% than that of the last year.
