Brief Summary
The goal of this open label, single-arm clinical study is to learn about the safety and efficacy of CS-101 in treating β-thalassemia.
Detailed Description
CS-101 is an autologous CD34+ cell suspension, edited by ex vivo base editing technology, which modifies the BCL11A binding site in HBG promoter, so that it loses the ability to bind to BCL11A, which ...

- Previously received allogeneic hematopoietic stem cell transplantation or gene(edited) therapy.
- Subjects have available related fully matching donors and are eligible and prepared for allogeneic hematopoietic stem cell transplantation.
- Those with active infections, including but not limited to: HIV, hepatitis B, hepatitis C, cytomegalovirus, Epstein-Barr virus and treponema pallidum test positive, or known tuberculosis, parasitic infection, etc. who are judged by the investigator to be unsuitable to participate in this study.
