Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this trial is to evaluate the safety, tolerability, and pharmacodynamic activity of BBP-812, an investigational AAV9-based gene therapy, in pediatric participants with Canavan disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Canavan disease is an ultra-rare, profoundly disabling and fatal disease with no approved therapy. The Sponsor is developing BBP-812, an investigational gene therapy product for systemic delivery in participants with Canavan disease. BBP-812 is a recombinant adeno-associated virus serotype 9 (rAAV9) vector engineered to deliver the aspartoacylase (ASPA) transgene under control of a ubiquitous promoter to restore ASPA expression in both neuronal and non-neuronal cell types.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dose-Finding Phase: BBP-812 Dose Level 1 (Cohort 1)

Participants will receive a single intravenous (IV) infusion of low-dose BBP-812 on Day 0 in the dose-finding phase of the study.

Group Type EXPERIMENTAL

* Elevated urinary NAA and
* Biallelic mutation of the ASPA gene determined at Screening or documented in the participant's medical history.
* Active clinical signs of Canavan disease
* Participant is up to date on all immunizations per local guidelines

Exclusion Criteria
