First seen Nov 01, 2025 · Last updated Apr 26, 2026 · Updated 23 times

Summary

This study follows 41 children with Sanfilippo syndrome type A (MPS IIIA) who previously received the gene therapy ABO-102 in earlier trials. Researchers will monitor safety and measure how well the treatment controls the disease over time, including thinking skills and chemical markers in spinal fluid. The goal is to see if the benefits last and if any side effects appear years after treatment.
