An Open-label Study of a Gene Therapy Product (Vebeglogene Autotemcel) in Transfusion Dependent Beta-Thalassemia
Trial Parameters
Brief Summary
This is an interventional study to evaluate the safety and efficacy of autologous Hematopoietic Stem and Progenitor Cells (HSPCs) transduced with lentiviral vector encoding functional hemoglobin subunit beta (HBB) gene in patients with transfusion-dependent beta-thalassemia.
Eligibility Criteria
Inclusion Criteria: * Patients or parent(s)/legal guardian(s) willing and able to complete the informed consent process and comply with study procedures and visit schedules. * Diagnosis of beta-thalassemia and a history of RBCs transfusions. * Documented baseline, or pretransfusion, Hb≤7 g/dL. * Availability of an adequate and well-documented transfusion history. Exclusion Criteria: * Active bacterial, viral, fungal, or parasitic infection. * A white blood cell (WBC) counts\<3×10\^9/L, and/or platelet counts\<100×10\^9/L not related to hypersplenism. * Uncorrected bleeding disorder. * Presence of severe diseases that judged not compatible with the study procedures, such as severe hepatic disease, kidney disease, lung disease, and/or cardiovascular disease. * Uncontrolled seizure disorder. * Any evidence of severe iron overload that, in the investigator's opinion, warrants exclusion. * Prior autologous hematopoietic stem cell transplantation. * Prior receipt of gene therapy.
