Muscular dystrophy (MD) is a spectrum of genetic disorders characterized by muscle weakness that, in severe forms, can lead to loss of ambulation and early mortality. There is a high unmet need for effective treatments that can meaningfully delay or halt progressive muscle degeneration in Duchenne muscular dystrophy (DMD), the most common childhood-onset form, as well as in other forms of MD. The standard treatment option for MD patients is glucocorticoids, which have proven effective in delaying loss of ambulation. Recent conditional approvals of genotype-specific, disease-modifying therapies such as Sarepta\u2019s Exondys 51, Vyondys 53, and Amondys 45, Nippon Shinyaku\u2019s viltolarsen, and PTC Therapeutics\u2019 Translarna have expanded treatment options for DMD patients; however, there are lingering concerns about the clinical efficacy of these drugs. Additionally, many therapies with diverse mechanisms of action are being developed to treat other forms of MD, including limb-girdle MD and Becker MD. Overall, there is still high unmet need for additional and, ideally, more-effective medications for DMD and other forms of MD<\/p>\n
