Medivir substance effective against resistant Hepatitis B virus in laboratory tests

Medivir substance effective against resistant Hepatitis B virus in laboratory tests nd Dr Hong Zhang from Medivir presented new results with FLG at the 2 International Symposium on Antiviral Drugs, Beijing 5-7 November. This substance is in preclinical development primarily against hepatitis B infections. In laboratory tests performed at Southern Research Institute, Maryland FLG has recently shown effect against lamivudine-resistant hepatitis B virus. Lamivudine (3TC, Glaxo) is one of the most effective drugs against hepatitis B available today. Resistance development is an increasing problem in treating hepatitis B and combination therapy is likely to be necessary in the future. WHO has estimated that 350 million people are chronically infected with hepatitis B of which approximately one third are in China. The most common therapy today is treatment with interferon, which has limited efficacy and significant side-effects. Medivir's patent applications on FLG prodrug will last to year 2017.
