[Future prospects for hepatitis C treatment: without interferon and ribavirin?]

Abstract

The hepatitis C virus is an important health problem worldwide. Currently, the standard treatment of genotype 1 chronic hepatitis C is the combination of pegylated interferon, ribavirin and a first-generation protease inhibitor: telaprevir or boceprevir. This triple therapy has improved the efficacy of treatment but has also increased regimen complexity, costs, and the number of adverse effects (mainly hematological and cutaneous). Unfortunately, viral response rates are still suboptimal in patients with cirrhosis, particularly those with a prior null response. Moreover, studies carried out in clinical practice have shown that the presence of advanced fibrosis confers a high risk of developing severe adverse effects during treatment (infection, decompensation and even death). It is therefore essential to select candidates for triple therapy according to their risk of complications and possibilities for cure. In this scenario, interferon (and ribavirin)-free combinations are very safe and well tolerated first-line treatments. This review describes the current treatment of hepatitis C as well as the latest results of studies combining distinct direct antiviral agents without interferon. It is hoped that these drugs will be available shortly, although their cost may be high. Consequently, it is essential to identify those patients who could derive the greatest benefit from these treatments.
