Abstract | BACKGROUND: Increased oxidative stress and subsequent mitochondrial damage are important pathways for liver damage in chronic hepatitis C virus (HCV) infection; consequently, therapies that decrease mitochondrial oxidative damage may improve outcome. The mitochondria-targeted anti-oxidant mitoquinone combines a potent anti-oxidant with a lipophilic cation that causes it to accumulate several-hundred fold within mitochondria in vivo. AIMS: METHODS: Thirty HCV patients who were either non-responders or unsuitable candidates for standard-of-care (pegylated interferon plus ribavirin) were randomized to receive mitoquinone (40 or 80 mg) or placebo once daily for 28 days, and serum aminotransferases and HCV RNA levels were measured. RESULTS: Both treatment groups showed significant decreases in absolute and percentage changes in serum alanine transaminase (ALT) from baseline to treatment day 28 (P<0.05). There was also a significant difference between incremental area under the curve for ALT between baseline and day 28 for the 40 mg treatment group against placebo (P<0.05). The differences in plasma ALT activity from baseline to day 28 in both mitoquinone groups compared with placebo did not reach significance (P>0.05). There was no change in HCV load on mitoquinone treatment. CONCLUSIONS:
