What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Sustained Virologic Response (SVR) Rate	Evaluation of sustained virologic response to antiviral C treatment depends of time of liver transplantation that can be performed between week 16 and week 96 of the trial: If the liver transplant is realized after the discontinuation of antiviral C treatment,sustained virologic response should be evaluated 6 months after the discontinuation of antiviral C treatment and at the time of liver transplantation.; If the liver transplant is realized before the discontinuation of antiviral C treatment,sustained virologic response should be evaluated at the time of liver transplantation.	Week 24 after the discontinuation of antiviral C treatment and at the time of liver transplantation or at the time of liver transplantation

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of participants with adverse events as a measure of safety and tolerability	Information on adverse events will be collected by the investigator during medical visits and reported in the CRF. Adverse events will be classified as: a) Flu-like symptoms b) Musculoskeletal symptoms c) Neurologic symptoms d) Psychiatric symptoms e) Constitutional symptoms	From week 0 to week 144
Perceived symptoms	Information on symptoms as perceived by the patients will be collected through self-administered questionnaires.	at day 0, week 24, week 48 and every 24 week up liver transplant - post liver transplant: day 0, week 24 and week 48
Compliance rate.	Treatment compliance will be assesses through a self-administered questionnaire reporting the number of medication doses prescribed and taken by the participants	week 12, week 24, week 36, week 48, week 72 - after Liver transplant:Day 0
SVR prognosis factors	Participants with undetectable plasma HCV-RNA 24 weeks after treatment cessation and/or liver transplantation will be considered as SVR. Factors potentially associated with SVR will be studied through a logistic regression analysis. These factors include demographical (age, gender), virological (baseline viral load), clinical (disease severity measured by MELD score) and genetic factors (IL28B polymorphism: TT, CT, or CC)	Week-4 up week 144
The predictive value of on-treatment HCV RNA on SVR	Quantitative assessment of HCV RNA during treatment will be performed at weeks 1, 4, 5, 6, 7, 8, 12, 16, 20, and 24 and correlated to SVR	During weeks 1, 4, 5, 6, 7, 8, 12, 16, 20, and 24 (before transplantation)
The percentage of virologic failure	Virological failure is defined as an increase of HCV RNA of at least 1 log IU/mL during treatment, or by the reappearance of positive viremia during treatment, after an initial negative result	week 4 and week 48
The percentage of relapse after transplantation	Virological relapse is characterized by an HCV RNA negative at the end of treatment but becoming detectable after cessation of therapy. The proportion of patients with virological relapse will be determined	Between week 16 and week 144
Boceprevir resistant mutations	The proportion of patients with emergence of resistant mutations to boceprevir in case of detectable viral load during treatment (from W5) and after the discontinuation of treatment in the event of virologic failure will be assessed	From week 5 to week 48 or after week 48
Resistant mutations in plasma and liver samples (both explanted liver and graft)		Week 16 up to week 96
Sepsis according to Systemic Inflammatory Response System (SIRS) Criteria		From day 0 to week 72
Cirrhosis impairment	Cirrhosis impairment will be assessed by studying: the mean variation of MELD score between baseline and end of therapy; the proportion of patients with a MELD score increased by at least 3 points (in case of baseline MELD>15) or 5 points (in case of baseline MELD<15)	From day 0 to week 72
Survival after transplantation		Week 16 up to week 96
Survival rate within one year after liver transplantation		week 64 up to week 144
The mean time elapsed between registration on the transplantation list and the date of transplantation		Week16 up to week 96
Measurement of the residual plasma concentration (Cres) of ribavirin		at Week 4 and Week 8
Area Under the Plasma Concentration Time Curve (AUC) From 0-8h of Boceprevir		At week 16 and at week 24 and if the MELD score has changed by more than three points
Maximum Plasma Concentration (Cmax) of Boceprevir		At week 16 and at week 24 and if the MELD score has changed by more than three points
Time of Maximum Plasma Concentration (Tmax) of Boceprevir		At week 16 and at week 24 and if the MELD score has changed by more than three points
Minimum Plasma Concentration (Cmin) of Boceprevir		At week 16 and at week 24 and if the MELD score has changed by more than three points
Correlation study between the presence of an elevated level of IP-10 during triple therapy and the absence of sustained virologic response	Plasma aliquots will be performed in all patients of the trial at day 0 before liver transplant and day 0 post liver transplant to measure IP10. Evaluation will be performed at the end of the trial for all patients recruited. The association between IP-10 level and SVR will be assessed	From week 4 to week 48
Histological severity of HCV recurrence after liver transplantation	Histological severity will be assessed by the METAVIR score at 1 month (if early recurrence), at 6 months, 1 year after transplantation in case of non-response/relapse before transplantation . Liver transplantation can be performed between week 16 and week 96	At week 20 up to week 100, at week 40 up to week 120, at week 64 up to week 144
Insulin Resistance (HOMA-IR)		At baseline, week 48 and at the last follow-up visit
Virological Response in participants with and without Insulin Resistance		At week 4, 8, 16, 28 and 48 during therapy
Relationship between the presence of a polymorphism in the IL28B gene (donor and recipient) and SVR	Whole blood aliquots (DNA bank) will be performed at the Day 0 visit to measure IL28B polymorphism. Evaluation will be performed at the end of the trial for all patients recruited. The SVR rate will be compared between the different IL28B phenotypes (CC, CT and TT).	After week 144
Relationship between the presence of a polymorphism to the ITPA gene and the onset of hemolytic anemia	Whole blood aliquots (DNA bank) will be performed at the Day 0 visit for ITPA gene measure. Evaluation will be performed at the end of the trial for all patients recruited. The proportion of patients with occurrence of hemolytic anemia will be compared according to the ITPA polymorphism	After week 144
