A single injection of RG-101, an experimental drug that targets the micro RNA miR-122 in liver cells, reduced hepatitis C virus (HCV) levels by more than 4 log in people with HCV genotypes 1, 3, and 4, and 21% of treated patients still had undetectable virus levels 28 weeks after dosing, according to research presented at the AASLD Liver Meeting in November.
