Hepatitis C, Chronic Clinical Trial
Official title:
Evaluation of Safety and Efficacy of Generic Sofosbuvir and Ribavirin for Treatment-naive Adults Chronically Infected With Genotype 2 Hepatitis C Virus: an Open-label, Multicenter Confirmatory Study
This study aimed to evaluate the safety and efficacy of generic sofosbuvir, an investigational anti-hepatitis C virus (HCV) drug, combined with weight-adjusted ribavirin for treatment-naive Chinese adults chronically infected with genotype 2 HCV, the second most prevalent genotype in China. One hundred and thirty-two (132) subjects, including one hundred and twenty (120) non-cirrhotics and twelve (12) compensatory cirrhotics, were medicated with sofosbuvir 400 mg daily combined with weight-adjusted ribavirin 1000-1200 mg daily. The treatment course lasted 12 successive weeks and thereafter all the study participants entered into a 12-week treatment-free follow-up period.
It is estimated that China has a population of over 10 million infected with HCV and also a highly variable HCV genotype geographic distribution. Genotype 2 HCV is reported to be the second most common type (~25%) in Chinese population and associated with a high risk of acute liver disease exacerbation and other extrahepatic diseases. Sofosbuvir is a pan-genotypic HCV ribonucleic acid (RNA) polymerase inhibitor directing at HCV RNA replication. Genotype 2 chronic hepatitis C has a high treatment response to the combined regimen of peginterferon and weight-adjusted ribavirin. The all-oral combination regimen of sofosbuvir and ribavirin is expected to completely suppress genotype 2 HCV replication in subjects chronically infected with HCV and achieve a sustained virologic response, namely, HCV not detected or below a predefined limit in plasma, 12 or 24 weeks after cessation of treatment. ;
