uniQure receives Orphan Drug Designation for AMT-191 in Fabry Disease

uniQure announced that the U.S. Food and Drug Administration has granted Orphan Drug Designation to AMT-191, uniQure’s investigational gene therapy for the treatment of Fabry disease, a rare, inherited genetic disease. In August 2024, uniQure announced the dosing of the first patient in its U.S., multi-center, open-label Phase I/IIa trial of AMT-191. The Phase I/IIa clinical trial of AMT-191 will be conducted in the United States. The multicenter, open-label trial consists of two cohorts with up to six adult male patients each: a low-dose cohort of 6×1013 gc/kg and a high-dose cohort of 3×1014 gc/kg delivered through a one-time intravenous infusion. Patients will continue to receive their regular enzyme replacement therapy until the criteria for withdrawal is met and will be followed for a period of 24 months. The trial will explore the safety, tolerability, and early signs of efficacy by measuring the expression of lysosomal enzyme aGLA-A.
