                                   5. Maintenance therapy with low-dose of PegIFN. Non-
                                   sustained responders to SoC, with advanced fibrosis or cirrhosis,
                                   have a high risk for disease progression and complications. Two
                                   large multicentre trials have evaluated the benefits of
                                   maintenance therapy with low-dose PegIFN in this group:
                                   –   the COPILOT study (Colchicine vs. PegIFN alfa-2b 0.5
                                      µg/kg/week Long Term) (Afdhal 2008)
                                   –   the HALT-C study (Hepatitis C Antiviral Long-Term
                                      Treatment Against Cirrhosis with PegIFN alfa-2a 90
                                      µg/week) (Di Bisceglie 2008)
                                   In the COPILOT study 555 patients with prior failure to
                                   interferon-based therapy were randomized to receive either
                                   PegIFN alfa-2b 0.5 µg/kg/week (n=286) or colchicine 0,6 mg twice
                                   daily (n=269). No differences were observed between the two
                                   groups with respect to progression of the CP score, development
                                   of complications of portal hypertension or HCC.
                                   The HALT-C trial was a prospective, randomized, controlled
                                   study of long-term maintenance therapy with PegIFN alfa-2a 90
                                   µg/week (n=517) or no treatment (n=533) for 3.5 years in
                                   patients with chronic hepatitis C (CHC) and advanced fibrosis or
                                   cirrhosis (Ishak score 3-6) who did not achieve SVR after
                                   interferon-based therapy. By the end of the study period, there
                                   was no difference between the control and treated groups in the
                                   frequency of death, hepatic decompensation or development of
                                   HCC. Overall, the COPILOT and HALT-C trials showed that
                                   maintenance therapy with low-dose PegIFN alfa-2a or alfa-2b
                                   does not reduce the rate of liver-related death, clinical
                                   disease progression and complications over a period of up to 4
                                   years.


                                   6. Triple-combination therapy. Triple therapy combination of
                                   PegIFN/RBV with a protease inhibitors (telaprevir or boceprevir)
                                   in HCV genotype 1-experienced patients has been shown to
                                   produce high rates of virological response in both prior relapsers
