An Observational Study in Children With CLN2 Batten Disease
- Conditions
- Neuronal Ceroid Lipofuscinosis Type 2 (CLN2)
- Registration Number
- NCT04462692
- Lead Sponsor
- REGENXBIO Inc.
- Brief Summary
This is a prospective, longitudinal natural history study to document the progression of ocular manifestations of CLN2 disease among a community-dwelling population of pediatric participants affected by this disease.
- Detailed Description
CLN2 is a rare disease with limited available ocular natural history data. While current standard of care slows motor degeneration, it is not known to treat the ocular manifestations of disease. This study is planned to document, through prospective data collection, ocular disease progression in children with a clinical presentation consistent with CLN2 Batten disease undergoing current standard of care for their condition. No investigational product is administered in this observational study.
