Abstract

An antisense molecule capable of binding to a selected target site to induce exon skipping in the dystrophin gene, as set forth in SEQ ID NO: 1 to 202.

Claims

1. An antisense oligonucleotide of 30 bases comprising the base sequence CUCCAACAUC AAGGAAGAUG GCAUUUCUAG (SEQ ID NO:

181), in which the uracil bases are thymine bases, wherein the antisense oligonucleotide is a morpholino antisense oligonucleotide, and wherein the antisense oligonucleotide is chemically linked to a polyethylene glycol chain.

2. A pharmaceutical composition comprising an antisense oligonucleotide of 30 bases comprising the base sequence CUCCAACAUC AAGGAAGAUG GCAUUUCUAG (SEQ ID NO:

181), in which the uracil bases are thymine bases, wherein the antisense oligonucleotide is a morpholino antisense oligonucleotide, and wherein the antisense oligonucleotide is chemically linked to a polyethylene glycol chain, and a pharmaceutically acceptable carrier.
