AMONDYS 45 (casimersen) is an antisense oligonucleotide that induces exon 45 skipping in dystrophin pre-mRNA, enabling production of internally truncated dystrophin protein in eligible Duchenne Muscular Dystrophy (DMD) patients. Delivered intravenously, it targets a genetically defined patient subset with mutations amenable to exon 45 skipping. This precision mechanism represents a paradigm shift in DMD treatment from broad corticosteroid symptomatic management to mutation-specific genetic therapy.
Product is in peak commercial phase with moderate competitive pressure (8/10); brand team likely at full capacity managing market penetration and real-world evidence generation.
