Casimersen, sold under the brand name Amondys 45, is an antisense oligonucleotide medication used for the treatment of Duchenne muscular dystrophy (DMD) in people who have a confirmed mutation of the dystrophin gene that is amenable to exon 45 skipping.[1][2][3][4] It is an antisense oligonucleotide of phosphorodiamidate morpholino oligomer (PMO).[1] Duchenne muscular dystrophy is a rare disease that primarily affects boys.[5] It is caused by low levels of a muscle protein called dystrophin.[5] The lack of dystrophin causes progressive muscle weakness and premature death.[5]

The most common side effects include upper respiratory tract infections, cough, fever, headache, joint pain and throat pain.[2][5]

Casimersen was approved for medical use in the United States in February 2021,[1][2][6] and it is the first FDA-approved targeted treatment for people who have a confirmed mutation of the DMD gene that is amenable to skipping exon 45.[2]
