Triple-Therapy in Patients With HCV Genotype 3 Who Previously Failed Treatment (LeeG3)
Triple-Therapy With PegInterferon α-2b + Ribavirin + Boceprevir in Patients With HCV Genotype 3 Who Previously Failed Treatment With PegInterferon α + Ribavirin
Study Overview
Detailed Description
i) Obtain preliminary information on the association between important baseline and on-treatment factors and SVR in this patient population. Variables to be examined may include gender, age, advanced fibrosis or cirrhosis (F3 or F4 estimated by Fibroscan), baseline viral load, RVR, wk 8 viral load, end-of-treatment viral response.
ii) Evaluate adverse events. iii) Evaluate viral resistance.

Experimental: Boceprevir
|
All patients will receive a 4-week lead-in with Peginterferon and Ribavirin therapy, followed by 24 weeks of Pegetron 1.5microg/kg + weight-based ribavirin + boceprevir 800mg tid.
HCV RNA (Cobas TaqMan) will be measured at baseline and at treatment weeks 4, 6,8,12,16,20,24 and 28, and post-treatment weeks 12 and 24 (to obtain SVR-12 and SVR-24 results).

Sustained Virologic Response (SVR) at 24 Weeks Post Treatment
Time Frame: 24 weeks after treatment
|
Sustained Virologic Response (SVR) is evaluated 24 weeks after end of treatment and defined as undetectable plasma HCV-RNA at follow up week 24.
HCV RNA is measured using Cobas TaqMan.Of the 6 subjects who completed the treatment, 3 obtained SVR at 24 weeks post treatment.
