EASL 2013: HCV Protease Inhibitor Simeprevir Pushes Triple Therapy Cure Rate Up to 80%

A second-generation HCV protease inhibitor, simeprevir (formerly TMC435), cured around 80% of previously untreated people with genotype 1 hepatitis C infection when combined with pegylated interferon and ribavirin, Michael Manns of the University of Hannover Medical School reported last week at the EASL International Liver Congress (EASL 2013) in Amsterdam. Overall, 91% of simeprevir-treated patients able to stop all treatment after 24 weeks.

EASL 2013: Daclatasvir plus Interferon Cures More Genotype 2/3 Hepatitis C Patients

Adding the HCV NS5A inhibitor daclatasvir to pegylated interferon and ribavirin for 12 or 16 weeks led to higher response rates for previously untreated people with genotype 2 or 3 hepatitis C, according to results from the COMMAND study reported last week at the EASL International Liver Congress(EASL 2013) in Amsterdam. People with genotype 3, however, did not respond as well as those with genotype 2.

An all-oral regimen containing 3 next-generation antivirals taken for either 12 or 24 weeks produced sustained virological response in more than 90% of previously untreated genotype 1 chronic hepatitis C patients in a Phase 2a study, according to a late-breaking poster presentation at the EASL International Liver Congress(EASL 2013) in Amsterdam.

EASL 2013: Sofosbuvir + Interferon/Ribavirin Cures 90% of People with Hard-to-Treat HCV Genotypes

Adding the second-generation HCV polymerase inhibitor sofosbuvir (formerly GS-7977) to pegylated interferon plus ribavirin led to a sustained response rate of 89% for treatment-naive patients with HCV genotype 1 in the NEUTRINO study, researchers reported at the EASL International Liver Congress(EASL 2013) last week in Amsterdam. High rates were also seen for the less common genotypes 4, 5 and 6.

EASL 2013: Triple-Drug HCV Therapy Comes with High Risk of Serious Adverse Events for Cirrhotics

Currently available triple therapies for hepatitis C using HCV protease inhibitors carry a high risk of serious side effects for patients in the most urgent need of treatment, and these individuals have only a moderate chance of being cured, according to findings from studies of telaprevir and boceprevir treatment in cirrhotic patients at liver centers in France and Austria reported last week at the 48th International Liver Congress in Amsterdam. In the Austrian study almost 1 in 10 cirrhotic patients were hospitalized with sepsis during triple therapy.
