Application Number:	15/359,152
Patent Claims:	1. A method of treating Duchenne muscular dystrophy (DMD) in a human subject who has a mutation of the DMD gene that is amenable to exon 51 skipping, comprising administering to the human subject a composition comprising eteplirsen and a phosphate-buffered saline at a dose of eteplirsen of about 30 mg/kg to about 50 mg/kg for a period of time sufficient to increase the number of dystrophin-positive fibers in a subject to at least 20% of normal. 2. The method of claim 1, wherein eteplirsen is administered for a period of time sufficient to increase the number of dystrophin positive fibers to about 50% of normal. 3. The method of claim 1, wherein the dose of eteplirsen is about 30 mg/kg. 4. The method of claim 1, wherein the composition is administered by systemic administration. 5. The method of claim 1, wherein the composition is administered once weekly by infusion. 6. The method of claim 1, further comprising administering a steroid to the human subject. 7. The method of claim 6, wherein the human subject is administered a stable dose of the steroid for at least 24 weeks prior to the first dose of eteplirsen. 8. The method of claim 7, wherein the steroid is a glucocorticoid. 9. The method of claim 1, wherein the human subject is 7 to 13 years of age. 10. The method of claim 9, wherein the human subject is a boy. 11. The method of claim 7, wherein the human subject is 7 to 13 years of age. 12. The method of claim 11, wherein the human subject is a boy.
