Brief Summary:
This is a non-randomized, open-label study examining the safety and efficacy of betaine in addition to standard anti-viral therapy in genotype 1 hepatitis C non-responders or relapsers to previous pegylated interferon plus ribavirin. Betaine (20 gm/day) in 2 divided doses will be added to Peginterferon alpha 2a (180 mcg) plus weight-based Ribavirin (1000 or 1200 mg/day, for body weight \< or \> 75 kg, respectively, for 48 weeks. Patients must be diagnosed with chronic hepatitis C, genotype I, and have undergone therapy for hepatitis C with pegylated interferon plus ribavirin. Subjects will be followed for safety, tolerability, hepatitis C viral response and the effect on interferon gene signaling in peripheral blood mononuclear cells during therapy.
Detailed Description:
The primary objective is to examine the safety and efficacy of the betaine when combined with standard anti-viral therapy in previously treated adult subjects with chronic hepatitis C infected with genotype 1. The efficacy will be determined through comparison of the sustained viral response (SVR) to our protocol three-drug regimen (Betaine, Peginterferon plus Ribavirin) to that historically seen in relapsers and non-responders when retreated with standard therapy (Peginterferon and Ribavirin alone).
Secondary objectives include: (1) the comparison of the occurrence of rapid and early virologic response in the first 4 (Rapid Virologic Response, RVR) and 12 (Early Virologic Response, EVR) weeks of therapy, respectively, between the study regimen and historically treated patients. (2) the comparison of ALT normalization between the two groups. and (3) the effect on interferon gene signaling in peripheral blood mononuclear cells (PBMCs) between the two groups in the first 12 weeks of therapy and 6 months following the end of therapy.
