French Cohort of Therapeutic Failure and Resistances in Patients Treated With a Protease Inhibitor (Telaprevir or Boceprevir), Pegylated Interferon and Ribavirin
French Cohort of Therapeutic Failure and Resistances in Patients Treated With a Protease Inhibitor (Telaprevir or Boceprevir), Pegylated Interferon and Ribavirin
The purpose fo the study is to evaluate the efficacy defined by the sustained virological
 response (SVR), in patients with compensated cirrhosis treated with PEG-IFN, RBV and
 telaprevir or boceprevir in the French Early Access Program for the use of protease
 inhibitors or after the approval of these drugs through the the marketing authorization.
Methodology: Multicentric French national cohort with prospective collection of data and
 constitution of biobank, in HCV genotype 1 patients with compensated cirrhosis who failed to
 eradicate HCV with the combination PEG-IFN and RBV, treated with protease inhibitor
 (telaprevir or boceprevir), PEG-IFN and RBV, included in the French Early Access Program for
 the use of protease inhibitors or after approval of these drugs through the the marketing
 authorization.

 Primary objective: Evaluate the efficacy defined by the sustained virological response (SVR),
 in patients with compensated cirrhosis treated with PEG-IFN, RBV and telaprevir or boceprevir
 in the French Early Access Program for the use of protease inhibitors or after the approval
 of these drugs.

 Estimated enrollment: 900 patients treated in the French Early Access Program for the use of
 protease inhibitors and after the marketing authorization approval.

 Treatments:

 -  with telaprevir: triple combination with PEG-IFN alfa-2a, 180 µg/week, ribavirin 1000 to
 1200 mg/d according the body weight and telaprevir 750 mg/8h, for 12 weeks followed by
 PEG-IFN and RBV for 36 weeks for a total duration of treatment of 48 weeks.

 -  or with boceprevir: triple combination with PEG-IFN alfa-2b, 1,5 µg/kg/week, RBV 800 to
 1400 mg/d according the body weight and boceprevir 800 mg/8h. The treatment will begin
 after a lead in phase of PEG-IFN and RBV for 4 weeks, followed by a triple combination
 (PEG-IFN, RBV and boceprevir)during 44 weeks for a total duration of treatment of 48
 weeks.

 Estimated planning:

 -  study start date: February 2011

 -  enrollment period: 14 months

 -  subject participation duration: 12 months of treatment and 12 months of follow-up = 24
 months

 -  total study duration: 38 months. The last visit of the last enrolled patient is prevised
 in February 2014, the end of analysis on biobank in May 2014 (long term follow up of
 resistant mutants).

 Some blood samples will be preserved for scientific future research.

 Study design: national French multicentric cohort in patients with HCV-related cirrhosis
 treated in the French Early Access Program for the use of boceprevir or telaprevir or after
 the marketing authorization approval of these drugs associated with PEG-IFN and RBV with a
 collection of clinical and biological data and constitution of a biobank.
Inclusion Criteria:

 -  patients who need the criteria of French Early Access Program for boceprevir and
 telaprevir or after the marketing authorization approval:

 -  patients aged of 18 years or more with chronic hepatitis C

 -  relapsers or partial-responders or null-responders to treatment with PEG'IFN α2a
 or 2b associated or not with RBV

 -  chronic infection with genotype 1 HCV

 -  fibrosis Metavir score of 4 (cirrhosis)

 -  without decompensated liver disease

 -  naïve of direct anti-viral treatment

 -  without HIV or HBV co-infection

 -  signature of participation to the cohort
