NameTypeDescription
AMT-191DRUGA recombinant serotype 5 based adeno-associated viral vector (AMT-191) for one-time intravenous (IV) administration will be investigated in this study. This recombinant AAV5-based vector contains a coding deoxyribonucleic acid (DNA) sequence for human α-galactosidase A. Delivery of AMT-191 to the systemic circulation is expected to result in a therapeutic effect by promoting the liver expression of the lysosomal enzyme GLA in plasma levels in patients with Fabry disease.
