LA JOLLA, Calif., July 27, 2016 /PRNewswire/ -- Regulus Therapeutics Inc. (Nasdaq: RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that, as anticipated, it received written communication from the U.S. Food and Drug Administration (FDA) outlining information required to resolve the clinical hold for its Investigational New Drug (IND) for RG-101, which was announced on June 27, 2016.
In the written communication, the FDA requested the following from the company: detailed safety data analysis from preclinical and clinical studies; exploration of potential mechanisms of hepatoxicity in non-clinical models; review and input from independent hepatotoxicity experts; additional PK data from the US Phase 1 study; and a risk/benefit assessment for the proposed therapeutic regimens containing RG-101. The company anticipates submitting the necessary information by early Q4 2016. The FDA will notify Regulus of its decision within 30 days of receipt of the complete response to the issues.
"We are working expeditiously to resolve the issues outlined in the letter and anticipate a decision from the FDA in the fourth quarter," said Paul Grint, M.D., President and Chief Executive Officer of Regulus. "Timelines of on-going studies have not been impacted by the clinical hold, and we remain on track to deliver follow-up results from ongoing RG-101 studies at upcoming relevant scientific meetings later this year."
Regulus Therapeutics Inc. (Nasdaq: RGLS) is a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs. Regulus has leveraged its oligonucleotide drug discovery and development expertise to develop a well-balanced microRNA therapeutics pipeline complemented by a maturing microMarkersSM biomarkers platform and a rich intellectual property estate to retain its leadership in the microRNA field. Regulus is developing RG-101, a GalNAc-conjugated anti-miR targeting microRNA-122 for the treatment of chronic hepatitis C virus infection, and RG-012, an anti-miR targeting microRNA-21 for the treatment of Alport syndrome, a life-threatening kidney disease driven by genetic mutations with no approved therapy. In addition, RG-125, a GalNAc-conjugated anti-miR targeting microRNA-103/107 for the treatment of NASH in patients with type 2 diabetes/pre-diabetes, has entered Phase I clinical development through its strategic alliance with AstraZeneca. Regulus is also advancing several programs toward clinical development in renal, hepatic and central nervous systems diseases, both independently and with our strategic alliance partners, Sanofi and AstraZeneca. Regulus' commitment to innovation has resulted in multiple peer-reviewed publications in notable scientific journals and has resulted in the formation of strategic alliances with AstraZeneca and Sanofi. Regulus maintains its corporate headquarters in La Jolla, CA. For more information, please visit http://www.regulusrx.com.
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.
About RG-101 for HCV
RG-101 is Regulus' wholly-owned, GalNAc-conjugated anti-miR targeting miR-122 for the treatment of HCV. In a completed Phase I human proof-of-concept study, Regulus demonstrated that treatment with a single subcutaneous dose of RG-101 as monotherapy resulted in significant and sustained viral load reductions in all treated HCV patients, including patients with difficult to treat genotypes, various liver fibrosis status and those who have experienced viral relapse after a prior IFN-containing regimen.
