Regulus also made several poster presentations highlighting the pharmacokinetics and pharmacodynamics of RG-101 in healthy volunteers, the preclinical pharmacokinetics, pharmacodynamics, and toxicity of RG-101, and the efficacy of RG-101 in a preclinical model of HCV. The ILC 2015 oral presentation slides and posters related to RG-101 will be accessible at www.regulusrx.com.
"With multiple presentations at this year's ILC meeting, Regulus is pleased to tell the complete development story of RG-101, our unique microRNA therapeutic for the treatment of HCV, with positive preclinical results through impressive data in our first-in-human clinical trial," said
"ILC 2015 is an extremely important meeting to advance the treatment of HCV and we are pleased to present such significant data on RG-101 in the oral late-breaking session," said

'Clinical Map Initiative' Goals for RG-101
Regulus' 'Clinical Map Initiative' outlines certain corporate goals to advance its microRNA therapeutics pipeline over the next several years. Regulus plans to investigate RG-101 in combination with oral agents to potentially shorten treatment durations, optimize clinical outcomes and potentially improve responses in certain underserved HCV patient populations, and further as a single agent (multiple doses of RG-101 in specific populations). In the near term, Regulus expects to initiate the above described studies in the second quarter of 2015 and to report interim data by the end of 2015.
Hepatitis C Virus Infection (HCV)
Hepatitis C is a result of a hepatocyte specific infection induced by the virus known as HCV. Chronic HCV may lead to significant liver disease, including chronic active hepatitis, cirrhosis, and hepatocellular carcinoma. Up to 185 million people are chronically infected with HCV worldwide, and more than 350,000 people die from HCV annually. The CDC estimates that there are currently approximately 3.2 million persons infected with HCV in the United States. HCV shows significant genetic variation in worldwide populations due to its frequent rates of mutation and rapid evolution. There are six genotypes of HCV, with several subtypes within each genotype, which vary in prevalence across the different regions of the world. The response to treatment varies from individual to individual underscoring the inadequacy of existing therapies and highlights the need for combination therapies that not only target the virus but endogenous host factors as well, such as microRNA-122. Regulus believes that its miR-122 antagonist, RG-101, may be a useful agent in emerging combination regimens to address difficult-to-treat genotypes and to potentially expand upon the current therapies available to clinicians treating HCV patients.
The discovery of microRNAs in humans during the last decade is one of the most exciting scientific breakthroughs in recent history. microRNAs are small RNA molecules, typically 20 to 25 nucleotides in length, that do not encode proteins but instead regulate gene expression. More than 800 microRNAs have been identified in the human genome, and over two-thirds of all human genes are believed to be regulated by microRNAs. A single microRNA can regulate entire networks of genes. As such, these molecules are considered master regulators of the human genome. microRNA expression, or function, has been shown to be significantly altered or dysregulated in many disease states, including oncology, fibrosis, metabolic diseases, immune-inflammatory diseases and HCV. Targeting microRNAs with anti-miRs, chemically modified, single-stranded oligonucleotides, offers a unique approach to treating disease by modulating entire biological pathways and may become a new and major class of drugs with broad therapeutic application.
