NCT01888900
Background: \- Some people who have chronic hepatitis C do not respond to the usual treatment with peginterferon and ribavirin. New chronic hepatitis treatments are being developed that may work better for different people. The treatments will look at how specific genes interact with the drugs. Researchers want to see how well these new drugs work in people whose chronic hepatitis C has not responded or only partly responded to the usual treatment drugs. Objectives: \- To compare new treatments for people with chronic hepatitis C. Eligibility: \- Individuals at least 18 years of age who have chronic hepatitis C that has not responded to standard treatments. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Liver scans and a biopsy will be taken before the start of treatment. * Participants will be separated into two groups. One group will have the new treatment drugs (assunaprevir and daclatasvir). The second group will have these two drugs as well as peginterferon and ribavirin. All participants will have an initial 4-day hospital stay with regular blood tests to see how the start of the treatment works. * The first group will take the new study drug tablets daily for 24 weeks. Those who do not respond to this treatment will also start to take peginterferon and ribavirin, and the treatment will continue for 24 weeks after starting the additional drugs. * The second group will take all four drugs according to the standard dosing schedule for 24 weeks. * Treatment will be monitored with frequent blood tests. Liver scans, biopsies, and other tests will be performed as directed by the study doctors. * Participants will have 24 weeks of regular followup visits.
