The goal of this clinical trial is to learn if a gene therapy called scAAV9.CB.CLN6 can treat children with CLN6 Batten disease (variant late infantile neuronal ceroid lipofuscinosis). The main questions it aims to answer are if he gene therapy safe and well tolerated, and if the gene therapy help slow disease progression or improve symptoms.
Participants will:
Receive a single dose of the gene therapy through an injection into the fluid around the spinal cord (intrathecal administration) Have regular study visits over 2 years for safety checks and assessments of disease progression Be followed for an additional 3 years in a long-term follow-up study

| Number of Participants With Treatment-Emergent Adverse Events as Assessed by CTCAE Version 5.0 | Treatment-emergent adverse events, including serious adverse events, hospitalizations, deaths, clinically significant laboratory abnormalities, and other clinically significant safety findings will be recorded from informed consent through Month 24. Adverse events will be assessed for intensity using CTCAE version 5.0 and for relationship to scAAV9.CB.CLN6. The number and percentage of participants with treatment-emergent adverse events will be summarized. | From informed consent through Month 24 |
| Measure | Description | Time Frame |

| Change From Baseline in Hamburg Rating Scale Score | The Hamburg Rating Scale will be used to assess disease status and function in participants with CLN6 disease. Change from baseline in Hamburg Rating Scale score will be summarized at scheduled post-baseline visits. | Baseline, Day 28, Month 3, Month 6, Month 9, Month 12, Month 18, and Month 24 |
