  2. Mucopolysaccharidosis II
  3. NCT06075537

An Extension Study of the Long-Term Safety, Tolerability, and Efficacy of Tividenofusp Alfa (DNL310) in Participants With Mucopolysaccharidosis Type II (MPS II) From Study DNLI-E-0002 or Study DNLI-E-0007

Mucopolysaccharidosis II Clinical Trial

Official title:
An Open-Label Extension to Investigate the Long-Term Safety, Tolerability, and Efficacy of DNL310 in Patients With Mucopolysaccharidosis Type II (MPS II) From Study DNLI-E-0002 or Study DNLI-E-0007

Clinical Trial Summary

This is a multiregional open-label extension (OLE) to assess the safety, tolerability, and efficacy of long-term treatment with tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant intravenous (IV) enzyme replacement therapy (ERT) for Hunter syndrome (MPS II). Participants who complete at least through the Week 49 visit in Study DNLI-E-0002 and do not discontinue study intervention early and participants who complete Study DNLI-E-0007 will be enrolled in this OLE. All participants will receive DNL310 for up to 5 years from the time of entry in this OLE. Participants, site staff, and the Sponsor will remain blinded to the original treatment assignment for participants entering this OLE from Study DNLI-E-0007.
