The idea behind gene therapy is to introduce, remove, or change a portion of person’s genetic code in order to cure a disease. Several gene therapy products are currently under development and there are two FDA-approved in vivo products, both using adeno-associated virus (AAV) vector gene delivery. Both of these treatments provide a functional copy of a gene that is not functioning properly in order to provide the body with the instructions for making the appropriate gene product or protein. One is for inherited retinal dystrophy and was approved in 2017, the other is for spinal muscular atrophy and was approved in 2019. In this podcast Dr. Nicholas Buss from REGENXBIO will discuss the science behind the nonclinical development of gene therapy products using AAVs.
