Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that surveyed gastroenterologists and hepatologists identify a therapy's effect on sustained virologic response in genotype 1 patients as the attribute that most influences their prescribing decisions in hepatitis C virus infection. Clinical data and the opinions of interviewed thought leaders indicate that the addition of Vertex/Janssen Pharmaceutica/Mitsubishi Tanabe's telaprevir or Schering-Plough's boceprevir to peginterferon/ribavirin provide advantages in this attribute over Roche's Pegasys (peginterferon-a-2a) plus ribavirin, the sales-leading treatment in the market.

The new report entitled Hepatitis C Virus: Protease and Polymerase Inhibitors on the Horizon to Revolutionize Treatment finds that a novel protease inhibitor that, when used in combination with peginterferon/ribavirin and achieves a significantly higher sustained virologic response in genotype 1 patients with only 24 weeks of treatment compared with the standard 48-week therapy with peginterferon/ribavirin, would earn a higher patient share in the United States than in Europe. The report finds that such an agent would earn a 60 percent patient share in the U.S. and a 40 percent patient share in Europe, according to surveyed U.S. and European gastroenterologists and hepatologists.

In 2008, Decision Resources' proprietary clinical gold standard for hepatitis C virus was Pegasys plus ribavirin because of its advantages in delivery and dosing. Based on available data and expert opinion, telaprevir plus ribavirin and a long-acting interferon will earn gold-standard status for hepatitis C virus following approval of telaprevir in 2011.

"New regimens that include a protease inhibitor, such as telaprevir or boceprevir, appear to have a competitive advantage in efficacy in patients infected with genotype 1 over the current peginterferon/ribavirin regimens," said Decision Resources Vice President John Lebbos, M.D. "Furthermore, the duration of therapy for genotype 1 patients can potentially be reduced with new three-drug regimens."
