Brief Summary
This study aimed to evaluate the safety and efficacy of KW-136, an investigational anti-hepatitis C virus (HCV) drug, combined with sofosbuvir for treatment of Chinese adults chronically infected with...
Detailed Description
It is estimated that China has a population of over 10 million infected with HCV and also a highly variable HCV genotype geographic distribution. A simple, universal, non-genotype-specific treatment r...
