Summary

The goal of this open label, single-arm clinical study is to learn about the safety and efficacy of CS-101 in treating patients with β-Thalassemia Major

Detailed description

CS-101 is an autologous CD34+(Cluster of differentiation 34) cell suspension, edited by ex vivo base editing technology, which modifies the BCL11A binding site in HBG(Hemoglobin Subunit Gamma) promoter, so that it loses the ability to bind to BCL11A, which can re-induce the production of γ-globin chain and increase the concentration of HbF(fetal hemoglobin) in the blood, compensating for the function of missing HbA(adult hemoglobin) to achieve clinical cure. The therapy addresses two major challenges in the current treatment of the disease: lack of matching donors and graft-versus-host diseases in allogeneic hematopoietic stem cell transplantation.
