New hope for rare brain disease: Long-Term safety data collected
NCT ID NCT01887938
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

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.
