Study summary

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

What researchers measure

Primary outcomes

  1. 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.

    Time frame: From informed consent through Month 24

Secondary outcomes

  1. 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.

    Time frame: Baseline, Day 28, Month 3, Month 6, Month 9, Month 12, Month 18, and Month 24

  2. Change From Baseline in Weill-Cornell Late Infantile Neuronal Ceroid Lipofuscinosis Scale Score

    The Weill-Cornell Late Infantile Neuronal Ceroid Lipofuscinosis Scale will be used to assess disease status and function in participants with CLN6 disease. Change from baseline in Weill-Cornell Scale score will be summarized at scheduled post-baseline visits.

    Time frame: Baseline, Day 28, Month 3, Month 6, Month 9, Month 12, Month 18, and Month 24

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 14, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
