Regulus to Present Updated Data Supporting RG-101 as Novel microRNA Therapeutic for the Treatment of HCV at The Liver MeetingĀ® 2015 (AASLD)

-Phase I Clinical Data will be Featured in Viral Hepatitis Plenary Session-

LA JOLLA, Calif., Oct. 2, 2015 /PRNewswire/ -- Regulus Therapeutics Inc. (NASDAQ:RGLS), a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, announced today that two abstracts related to RG-101, a GalNAc-conjugated anti-miR targeting microRNA-122 ("miR-122") for the treatment of chronic Hepatitis C Virus (HCV) infection, were accepted for presentation at The Liver MeetingĀ®, the 66th Annual Meeting of the American Association for the Study of Liver Disease (AASLD), to be held November 13-17, 2015 in San Francisco, CA.

Viral Hepatitis Plenary Session, November 17, 2015, 8:45am - 9:00am: A Single Dose of RG-101, a GalNAc-Conjugated Oligonucleotide Targeting miR-122, Results in Undetectable HCV RNA Levels in Chronic Hepatitis C Patients at Week 28 of Follow-up

Investigators will present extended follow-up data from the Phase I clinical study of RG-101 demonstrating that a single subcutaneous administration of either 2 mg/kg or 4 mg/kg of RG-101 as monotherapy resulted in HCV RNA levels below the limit of quantification in 6/22 patients with various HCV genotypes at week 28 of follow-up.

Poster Presentation, November 17, 2015, 8:00am - 12:00pm: Treatment with the Anti-miRNA122 Oligonucleotide RG-101 Results in a Decrease in IP-10 but Does Not Affect the Levels of Other Cytokines in Patients with Chronic Hepatitis C

Investigators will present data examining immunological changes observed in the plasma of patients who received a subcutaneous administration of RG-101 in the completed Phase I study.
Results demonstrated that HCV patients had significantly higher IP-10 levels at baseline compared to healthy controls. In HCV patients who received a subcutaneous administration of RG-101, a significant decline was observed in IP-10 serum concentrations compared to baseline, and RG-101 did not trigger a systemic immune activation
