Conclusion

We are once again preparing for a dramatic paradigm shift in approach to HCV infection. Worldwide, the epidemic proportions of HCV are coming to light both in the efforts of healthcare workers and governments in the underdeveloped world and in the burden from untreated and undiagnosed disease in the developed world. Numerous new drugs targeting various aspects of the HCV life cycle and the host are in development and clinical trials. Overall, combination therapies will be the rule. New combinations of DAA have synergistic effects, decrease the risk of resistance, and improve antiviral efficacy, are effective in different genotypes and have a favorable safety profile. Despite universal hope for all-oral regimens, pegylated-IFN is still in the literature. Many phase 1 and 2 clinical trials are still designed to demonstrate the safety of new DAA in combination with a pegylated interferon and ribavirin backbone and though the best response rates in interferon containing regimens still tend to be in favorable genotypes or IL-28 CC patients, the important benefit in these combinations is much shorter treatment duration of 12 weeks. Interferon-free combination regimens appear to be on the horizon, providing a new option in particular for patients with non-genotype 1 HCV, but there will still be treatment failures and resistance issues to be overcome, particularly in the treatment experienced population.
