 New Hope for Patients With Hepatitis C Infection
Scientists have identified a new range of protease inhibitors that aid treat patients with chronic hepatitis C infection. The treatments have been tested for efficacy and safety in combination with PegIFN-alpha and ribavirin in patients that have previously failed treatment (either non-responder or relapse).

Following different treatment and dosing, all of the trials demonstrated good response rates at key timepoints during the treatment period and with remarkably high sustained viral response rates.

These findings provide new hope for a growing number of HCV patients who cannot currently be effectively treated for chronic hepatitis. It is known that one of the most important determinants of poor treatment response is the genetic profile of the patient (with polymorphic mutation on IL28B gene for genotype 1). The current standard of care for chronic HCV is the combination of PegIFN-alpha and ribavirin6, but only 40-54% of patients infected with HCV genotype 1 achieve a sustained virological response (SVR).7 Retreatment with standard of care regimens only achieves SVR in 10-20% of patients but the new trial data released at the International Liver Congress show SVR rates of 40-80% when protease inhibitors are used even in the presence of the IL-28b genotype.

Professor Heiner Wedemeyer, EASL's Secretary General commented on the exciting new data being showcased at the congress: "Up until now, telling a patient that their treatment has failed has been particularly difficult knowing that there were no other options available and their disease was progressing. These results completely change the situation because patients who did not have successful treatment in the past now have a realistic chance of being cured. For both clinicians and patients, this is a new era in the treatment of viral hepatitis C, which is very exciting."

With new research currently being published in terms of treatment options, EASL is publishing the first clinical practice guidelines for the management of hepatitis C virus infection, which provide experts recommendations on the standard of care for the diagnosis, treatment and monitoring of patients with chronic HCV infection and associated complications. The guidelines will be updated to include new treatments once approved by the European Medicines Agency (EMA).
