Tests treatment safety and results for β-thalassemia
Official title Safety and Efficacy of Gene Modified Autologous Hematopoietic Stem Cells to Treat Transfusion-dependent Beta-thalassemia
ClinicalTrials.gov ID: NCT05773729
What this study is testing
What is BD211?
BD211 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for β-thalassemia.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study will be intented to evaluate the safety, tolerability, and engraftment efficacy after myeloablative preconditioning and transplantation of autologous CD34+ hematopoietic stem cells transduced with a lentiviral vector encoding the human βA-T87Q-globin gene in patients with transfusion-dependent (TDT) β-thalassemia.
