Study Endpoints

Primary Endpoints

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Baseline to Follow-up (Week 628)

An AE is any noxious, pathologic, or unintended change in anatomical, physiologic, or metabolic function as indicated by physical signs, symptoms, or laboratory changes occurring in any phase of a clinical study, whether or not considered investigational drug product-related. TEAEs are defined as all AEs occurring or worsening at or after the first dose of investigational drug product in HGT-MLD-071 or ongoing from HGT-MLD-070 at the time of enrollment into HGT-MLD-071.

Presence of Anti-HGT-1110 Antibodies in Cerebrospinal Fluid (CSF) and Serum
Baseline until end of the study (Week 624)

The presence of anti-HGT-1110 antibodies in CSF and serum will be assessed.
