- If successful, BridgeBio's gene therapy could be the first approved therapeutic option for children born with Canavan disease, a devastating and life-threatening condition
- The Canavan disease program is part of BridgeBio's growing gene therapy portfolio, which includes clinical candidates for congenital adrenal hyperplasia (CAH) and classic galactosemia (severe GALT deficiency), and preclinical programs for TMC1 hearing loss, tuberous sclerosis, cystinuria, and a genetic dilated cardiomyopathy
"Dosing the first patient in our Canavan disease trial is a significant achievement for our gene therapy team and we would not be here without the support of our collaborative partners in the patient, medical and scientific communities," said
"Based on the efficacy and safety data we've observed in our preclinical studies, we are hopeful that our investigational gene therapy can become a meaningful treatment option for children living with Canavan. Right now, these children only have access to supportive care because there are currently no approved therapies to treat this devastating disease," added
The Phase 1/2 open-label study is designed to evaluate the safety, tolerability, and pharmacodynamic activity of the company's AAV9 gene therapy, BBP-812, in pediatric patients with Canavan disease. In the initial dose-finding phase of the study, each patient will receive a single intravenous (IV) infusion of BBP-812. The primary outcomes of the study are safety, as well as change from baseline of urine and central nervous system N-acetylaspartate (NAA) levels. Motor function and development will also be assessed. Preclinical proof-of-concept data have shown the approach restores survival and normal motor function.
"Gene therapy is designed to treat diseases at their source, which for Canavan disease would be an extremely beneficial treatment option. Through this trial, we hope to provide evidence that this investigational therapy could represent a promising treatment option for Canavan patients and their families. We are grateful to the first family for participating," said
BridgeBio's gene therapy was originally developed by
"Throughout my career, I've been passionate about connecting with families in the Canavan community to understand how to help them through their journey. After decades of research and work, I'm thrilled that we have dosed the first patient in this trial. I'm hopeful that this represents a meaningful turning point for the Canavan community," said
BridgeBio's investigational AAV9 gene therapy for Canavan disease is one of the Company's 14 programs that are in the clinic or commercial setting for patients living with genetic diseases and genetically-driven cancers. An initial Phase 1/2 data readout for Canavan disease is expected in 2022. For more information about the CANaspire trial, visit TreatCanavan.com or ClinicalTrials.gov (NCT04998396).
BBP-812 is an investigational AAV9 gene therapy for Canavan disease. Using AAV gene therapy, BridgeBio seeks to deliver functional copies of the ASPA gene throughout the body and into the brain, potentially correcting the disease at its source. Preclinical proof-of-concept results in Canavan disease models have shown the approach restores survival and normal motor function. BBP-812 was granted Fast Track Designation, Rare Pediatric Drug Designation, and Orphan Drug Designation by the
