A new gene therapy has been approved in Europe, paving the way for its use in patients with beta-thalassaemia, a rare blood disorder. The treatment, Zynteglo, uses a lentiviral vector to deliver functional copies of a beta-globin gene into a patient’s haematopoietic stem cells in order to correct for a shortage of beta-globin. It was given a positive opinion by the European Medicines Agency on 29 March and a conditional approval by the European Commission on 29 May.
