Summary

This study followed 24 people with metachromatic leukodystrophy (MLD), a rare and serious brain disease, who were already receiving an experimental drug called HGT-1110. The main goal was to check for side effects and immune reactions over a long period. Researchers wanted to see if the drug remained safe for continued use.

Exclusion Criteria: 1. The participant is unable to comply with the protocol (example, is unable to return for safety evaluations, or is otherwise unlikely to complete the study) as determined by the investigator. 2. Undergoes bone marrow transplant (BMT), hematopoietic stem cell transplantation (HSCT), or gene therapy at any point during the study. 3.

The participant is pregnant or breastfeeding. 5. The participant is enrolled in another clinical study that involves clinical investigations or use of any investigational product (drug or drug delivery device) other than those used in HGT-MLD-070 (NCT01510028) within 6 months prior to study enrollment or at any time during the study. 6. The participant has a condition that is contraindicated as described in the SOPH-A-PORT Mini SIDDD Instructions for Use (IFU), including: 1. The participant has had, or may have, an allergic reaction to the materials of construction of the SOPH-A-PORT Mini S device. 2. The participant's body size is too small to support the size of the SOPH-A-PORT Mini S Access Port, as judged by the investigator. 3. The participant has a known or suspected local or general infection. 4. The participant is at risk of abnormal bleeding due to a medical condition or therapy. 5.
