Exon skipping and dystrophin restoration in patientswith Duchenne muscular dystrophy after systemicphosphorodiamidate morpholino oligomer treatment:an open-label, phase 2, dose-escalation study
This study explored the effects of AVI-4658, a phosphorodiamidate morpholino oligomer (PMO), on exon skipping and dystrophin restoration in Duchenne muscular dystrophy (DMD) patients. The open-label, phase 2, dose-escalation trial enrolled 19 boys aged 5-15, treated with doses ranging from 0.5 to 20 mg/kg weekly for 12 weeks. The main aim was to evaluate safety, with secondary goals to assess pharmacokinetics and the efficacy of exon 51 skipping and dystrophin …
