Material event and changes
- The U.S. Food and Drug Administration cleared Passage Bio’s Investigational New Drug application for PBML04.
- PBML04 is an adeno-associated virus delivery gene therapy being studied for infantile-onset MLD, a fatal inherited disease caused by mutations in the ARSA gene.
