However, recent paper summarizing the results of 1 year, nonrandomized-controlled trial (called Study-101, NCT03375164) with microdystrophin gene therapy using AAVrh74 vector, isolated from lymph nodes of rhesus monkeys and sharing 93% amino acid identity to AAV8 (SRP-9001; AAVrh74.MHCK7) in four young DMD patients [48], showed increased levels of dystrophin by 81.2% in the muscles without signs of severe adverse effects. This evidence concerns the gene DMD and Duchenne muscular dystrophy.
