Title:
MYOCARDIAL DYSFUNCTION THERAPEUTIC AGENT
Document Type and Number:
WIPO Patent Application WO/2019/240164
Kind Code:
A1
Abstract:
Established is a method for treating myocardial dysfunctions. Provided are: an oligonucleotide having 15-30 bases has complementary nucleotide sequences in some parts of an intron 55 region of a dystrophin gene, the oligonucleotide comprising 5'-TGTCTTCCT-3' or 5'-CAGCTTGAACCGGGC-3' (SEQ ID NO: 64) sequence (where T in the sequence may be U); and a pharmacologically acceptable salt or a solvate thereof. Provided is a prophylactic or therapeutic agent for myocardial dysfunction comprising said oligonucleotide, and a pharmacologically acceptable salt or solvate thereof. Provided is a Dp116 expression inhibitor comprising said oligonucleotide, and a pharmacologically acceptable salt or solvate thereof.
