NCT00277862

Brief Summary

Genotype 4 is the least-studied hepatitis C virus genotype and was considered a difficult to treat genotype due to the disappointing response of chronic hepatitis C genotype 4 to conventional interferon monotherapy. Recent reports showed that pegylated interferon and ribavirin combination therapy markedly increased the SVR rate to 55-70%. The duration of treatment has not been accurately defined. The main objective of this is to assess the duration of pegylated interferon ribavirin therapy in chronic hepatitis genotype 4 and assess the clinical utility of rapid and early virologic response in determining the optimal duration of peg interferon ribavirin therapy in chronic hepatitis C.
