Amsterdam, The Netherlands, Wednesday 24 April 2013: New data from a number of clinical trials presented for the first time at the International Liver Congress™ 2013 demonstrate encouraging results in the use of new direct-acting antiviral agents (DAAs) for the treatment of hepatitis C.
The following covers key results from the much anticipated Phase III trials conducted among HCV patients with a range of genotypes (GT 1 to 6) on DAA treatment.
EASL Secretary General Prof. Mark Thursz commented on the studies: "Unlike the US, in Europe and Asia genotype 3 is quite common. As such for European audiences the interferon-free results in genotype 3 are not as impressive as expected; however the side effect profile and lack of viral resistance means that longer treatment durations will be evaluated in the near future. In the meantime, we feel it's not time to bury pegylated interferon just yet."
"Many patients can tolerate 12 weeks of an interferon based regime particularly when it produces SVR rates of more than 90%; so clearly the results of the NEUTRINO study will be welcomed by clinicians and patients" added Prof. Thursz.
QUEST-1 and -2
Prof. Mark Thursz commented on the exciting protease inhibitor data showcased at the congress: "With genotype-1 the most common and most challenging type of HCV to cure, both studies have demonstrated extremely encouraging results with cleaner profiles than existing protease inhibitors. It is unlikely telaprevir and boceprevir will remain in the hepatic armoury for much longer."
"We truly are in a prime time for HCV therapy; these effective new treatment options have the potential to pave the way for future interferon-sparing regimens and we look forward to using them in the clinic" added Prof Thursz.
Other promising Phase II data presented at the congress may provide further options:
IFN and RBV Free Regimen
EASL Secretary General Prof. Mark Thursz commented further: "With such high success rates and increased safety and tolerability with novel DAAs, patients can be optimistic about oral treatment regimens in the not-too-distant future."

Notes to Editors
Worldwide estimates indicate that approximately 200 million people are chronically infected with the hepatitis C virus and at risk of developing liver cirrhosis and/or liver cancer. Every year, 3 million people are infected with hepatitis C and more than 350,000 people die from hepatitis C-related liver diseases.

About The International Liver CongressTM 2013
The International Liver Congress™ 2013, the 48th annual meeting of the European Association for the study of the Liver, is being held at the RAI Convention Centre in Amsterdam from April 24 – 28, 2013. The congress annually attracts in excess of 9000 clinicians and scientists from around the world and provides an opportunity to hear the latest research, perspectives and treatments of liver disease from principal experts in the field.
