Open-label studies, anecdotal reports, and in vitro scientific research indicate that 4-methylumbelliferone (active ingredient of the dietary supplement Heparvit®) may prevent and reverse the symptoms and complications of chronic infection with hepatitis B virus (HBV)and hepatitis C virus (HCV). This effect has been observed among naïve patients as well as those who are non-responders to interferon, commonly used as first-line therapy for HBV and HCV. In order to scientifically address the efficacy of this 4-methylumbelliferone on chronic viral hepatitis, a randomized, placebo-controlled, blinded study is needed.

It is hypothesized that 4-methylumbelliferone may reduce the impact and aggressiveness of HBV and HCV upon the liver, thereby slowing the progression to potentially life threatening liver diseases such as cancer and cirrhosis. This is a preliminary study designed to determine any indications under controlled conditions that may warrant further detailed clinical studies.
