How Vyondys 53 (golodirsen) works
Vyondys 53 (golodirsen) is an antisense oligonucleotide. It attaches to exon 53, a part of the gene that makes dystrophin. Dystrophin is a protein that keeps muscle cells intact and strong. In people with DMD, this protein is missing because of a mutation in exon 53. Vyondys 53 (golodirsen) works by exon skipping, meaning it cuts out exon 53 and its mutation from the finished protein. This helps to make a shorter but more functional dystrophin, which potentially provides strength to muscles and relief from symptoms of DMD.
