A Study of AAV9 Gene Therapy in Participants With Canavan Disease (CANaspire)
September 20, 2023 updated by: Aspa Therapeutics
A Phase 1/2 Open-Label Study of the Safety and Clinical Activity of Gene Therapy for Canavan Disease Through Administration of an Adeno-Associated Virus (AAV) Serotype 9-Based Recombinant Vector Encoding the Human ASPA Gene
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.
Study Overview
Detailed Description
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.

Description
Key Inclusion Criteria:
- Maximum age for inclusion is 30 months.
- Participant has stable health in the opinion of the investigator and as confirmed by medical history and laboratory studies with no acute or chronic hematologic, renal, liver, immunologic, or neurologic disease (other than Canavan disease).
