Dataset from Study of Viral Resistance to Antiviral Therapy of Chronic Hepatitis C (Virahep-C)

This study is designed to test the hypothesis that African-Americans respond less well to
combination pegylated interferon and ribavirin therapy than Caucasian-Americans who have
chronic hepatitis C genotype 1 and who were not previously treated with either interferon or
ribavirin. Reasons for differences in response, regardless of race, will be studied.
