Gene therapy for thalassemia ends need for transfusions in young children

Over 90 percent of patients with transfusion-dependent thalassemia, an inherited blood disorder, no longer needed monthly blood transfusions years after receiving gene therapy, according to an international Phase 3 clinical trial that for the first time included children younger than 12 years of age. Twenty-two patients were evaluated (ranging in age 4-34 years), including pediatric patients.
