Overview

KMM001 is a chimeric antisense oligonucleotide (ASO) designed to selectively inhibit the expression of myostatin (MSTN), a negative regulator of skeletal muscle growth. The molecule is composed of 2'-O-methyl RNA (2'-OMeRNA) and 2'-O,4'-C-ethylene-bridged nucleic acid (ENA) chemistry, which enhances its stability and binding affinity. KMM001 functions by targeting exonic splicing enhancer sequences within exon 1 of the MSTN gene, thereby blocking pre-mRNA maturation and reducing the production of mature myostatin protein. Preclinical studies have demonstrated that KMM001 is highly specific for myostatin and does not cross-react with the closely related GDF11. It is being investigated for the treatment of muscle-wasting conditions, including sarcopenia associated with chronic kidney disease (CKD) and spinal muscular atrophy (SMA).
