Regulus is focused on the discovery
and development of microRNA therapeutics.

microRNAs are members of a large class of non-coding RNAs of approximately 22 nucleotides in length that regulate most genes in the genome. A single microRNA can target and regulate up to hundreds of genes, and these genes are involved in biological networks or pathways. Dysregulated microRNA expression is involved in the initiation of many complex multi-factoral diseases, including cancer, inflammatory disease, fibrosis, and metabolic disease. microRNA therapeutics are oligonucleotide medicines that modulate the function of microRNAs, correcting the imbalance of gene expression and associated cellular pathways to treat human disease.

Regulus was formed in September 2007 by Alnylam Pharmaceuticals (NASDAQ:ALNY) and Isis Pharmaceuticals (NASDAQ:ISIS). Regulus benefits substantially from the collective therapeutic RNA expertise of its founding companies, including established proprietary oligonucleotide-based technologies, and broad and dominant intellectual property estates specific to chemically modified oligonucleotides. Regulus has access to over 850 patents and patent applications pertaining to oligonucleotide technologies useful for targeting microRNA therapeutics, and over 200 patents and patent applications directed to microRNA specific technologies.
