- Avrobio Inc (NASDAQ:AVRO) announced preclinical data demonstrating the efficacy and safety of AVR-RD-03 gene therapy in infantile-onset Pompe disease.
- Pompe disease is a lysosomal disorder caused by a mutation in the GAA gene. The lack of the enzyme encoded by GAA results in a toxic buildup of glycogen throughout the body and central nervous system.
- The results demonstrate that gene therapy using hematopoietic stem cells (HSC) significantly reduced the toxic accumulation of glycogen in a mouse model of Pompe disease, including in cardiac and skeletal muscle and the central nervous system (CNS).

- Eight months post-infusion, substrate levels in multiple treated tissues were nearly indistinguishable from normal mice.
- Additionally, new data from a separate study show that human HSCs were efficiently transduced, producing robust quantities of transgene product and GAA enzyme activity.
- AVROBIO plans to engage with regulatory agencies on the clinical development strategy for AVR-RD-03 in 2022 and plans to initiate a clinical trial in 2023.
- Price Action: AVRO shares are down 4.38% at $0.79 during the market session on the last check Wednesday.
