Antiviral therapy prevents recurrence of HCC, extends patients' lives, researchers report

Previous studies have shown that antiviral treatment reduces the incidence of hepatocellular carcinoma in patients with chronic hepatitis B. But now, researchers from the Division of Gastroenterology and Hepatology at Thomas Jefferson University are reporting that the antiviral therapy also prevents recurrence of HCC and extends patients' lives.

Monoclonal antibodies induce long-lasting, protective antiviral immune response

Monoclonal antibodies are the largest class of biotherapeutic drugs. When administered to infected organisms to blunt the propagation of pathogenic viruses, they may also induce a long-lasting and protective antiviral immune response similar to that achieved by vaccination. These results obtained in mice by the "Oncogenèse et Immunothérapie" group at the Institut de Génétique Moléculaire de Montpellier (CNRS/Universités Montpellier 1 and 2), have been published on 10 June in PLoS Pathogens.

Genetic variation can predict how people infected with hepatitis C react to treatment: Scientists

A small genetic change can predict how people infected with hepatitis C react to treatment, paving the way to personalised therapy for this difficult to treat disease, the annual conference of the European Society of Human Genetics will hear today (Sunday 13 June). Dr. Zoltan Kutalik, from the Department of Medical Genetics, University of Lausanne, Switzerland, will tell delegates that individuals with this change, in a gene encoding for the antiviral cytokine (cell-signalling molecule) interferon lamda, reacts less well to treatment.

Interim results from PROPEL study of RG7128 submitted as abstract to AASLD for Annual Liver Meeting

Pharmasset, Inc. announced today that the interim results from the PROPEL study conducted by its partner Roche demonstrate that RG7128 triple combination therapy was safe and well tolerated. In that study, the safety profile of RG7128 (1000mg BID or 500mg BID), when administered for 8 or 12 weeks with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin), the standard of care, was similar to the safety profile of SOC alone.
