    On February 15, the FDA approved the Casimersen (trade name: Ammondys 45) developed by Sarepta Therapeutics for the treatment of patients with Duchenne progressive muscular dystrophy (DMD) with a gene mutation exon 45 skipping type.

    This is the first drug approved for this type of genetic mutation DMD.

    DMD is a recessive genetic disease of the X chromosome.
    It is a muscular wasting disease caused by mutations in the dystrophin gene.
    There are 79 exons in the dystrophin gene.
    Exon mutations in DMD patients are mainly concentrated in the exons.
    Exons 45-55.

    The frameshift mutation of DMD gene directly causes the generated messenger nucleic acid (mRNA) to not encode the working dystrophin protein, and the exon deletion and frameshift cause severe symptoms of DMD.

    Casimersen is an antisense oligonucleotide therapy.
    It is Sarepta Therapeutics' third exon skipping drug developed using the PMO RNA platform to target Dystroglycan.

    The drug is a phosphodiamide morpholino oligomer (PMD), specifically designed to treat patients with DMD who are suitable for skipping exon 45.

    Casimersen was approved to use the accelerated approval channel this time.
    The drug has obtained the fast-track qualification granted by the FDA, the priority review qualification and the orphan drug qualification.

    Three antisense oligonucleotide therapies for the treatment of exon skip mutation DMD have been listed before, namely Eteplirsen (exon 51 skip mutation DMD), Viltolarsen (53 exon skip mutation DMD) and Golodirsen (53 exon Sub-jumping mutation (DMD).
