LA JOLLA, Calif., Jan. 27, 2017 /PRNewswire/ -- Regulus Therapeutics Inc. (Nasdaq: RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that it received written communication from the U.S. Food and Drug Administration (FDA) that the clinical development program for RG-101 remains on clinical hold. In June 2016, RG-101 was placed on clinical hold following the Company's submission of a second serious adverse event (SAE) of jaundice.
Late last year, Regulus submitted a complete response to the FDA's initial request for information, which included identification of a potential mechanism of hyperbilirubinemia. The Company also submitted a proposal to mitigate this risk. Subsequently, the FDA has requested the final safety and efficacy data from on-going RG-101 clinical and pre-clinical studies before reconsidering the clinical hold. These data will be available once the current study protocols are complete through 48 weeks of follow up, which is anticipated in the fourth quarter. The FDA also requested additional expert review of liver safety data in light of the proposed mechanism of hyperbilirubinemia.
"While we are disappointed that the clinical hold was not lifted at this time, we plan to continue to work with the FDA to address their additional requests as we seek the removal of the clinical hold," said Dr. Timothy Wright, Chief R&D Officer of Regulus.

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.
