CANbridge-UMass Chan Medical School Spinal Muscular Atrophy Gene Therapy Animal Data to be Presented at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting
-Novel Second-Generation SMA Gene Therapy Rescues Motor Function in Mice, Outperforms Benchmark Therapy
Burlington, Mass.; Beijing, China, May 5, 2023- CANbridge Pharmaceuticals Inc. (HKEX:1228), a leading China-based global biopharmaceutical company committed to the research, development and commercialization of transformative rare disease and rare oncology therapies, announced that data on the novel second-generation gene therapy, developed under the CANbridge and UMass Chan Medical School research agreement, will be presented at the American Society of Gene and Cell Therapy (ASGCT) 26th Annual Meeting, May 16-20, Los Angeles, CA.
The study reports that a novel second-generation hSMN1-AAV gene therapy vector, consisting of an endogenous SMN1 promoter and codon-optimized human SMN1 transgene in two different AAV serotypes, outperformed the benchmark gene therapy across several endpoints, including lifespan, weight gain and motor functions, in a mouse model of spinal muscular atrophy (SMA) when administered via intracerebroventricular (ICV) delivery. Furthermore, when delivered via ICV at one-tenth the dose used in both high- and low-dose cohorts in an earlier IV study, the second-generation gene therapy produced similar lifespan and body weight gains and improved motor functions. The benchmark therapy uses a vector similar to that used in the only gene therapy approved for SMA.
“ICV delivery of our second-generation SMA gene therapy at one-tenth the dose used in our IV study matches or improves upon the IV results we reported last year at ASGCT,” said Gerry Cox, MD, PhD, chief development strategist and interim chief medical officer, CANbridge Pharmaceuticals. “We believe that the transgene expression in our second-generation SMA gene therapy better mimics the natural physiological levels of SMN1 in transduced tissues. This gene therapy could offer a safer, more effective and more efficient clinical approach for treating SMA, which aligns with the CANbridge mission to create innovative therapies with improved market access to patients.”
Title: Low-dose intracerebroventricular delivery of a second-generation AAV gene therapy for spinal muscular atrophy achieves efficient and toxicity-free motor function rescue in mice
