Filter by:The purpose of this study is to evaluate the safety and efficacy of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) coadministered with ribavirin (RBV) in hepatitis C virus (HCV) genotype 1-infected adults taking methadone or buprenorphine ± naloxone.
This dose-escalating study is to evaluate the efficacy and the safety of different doses of a new bio-product Pegylated Recombinant Consensus Interferon Variant Solution for Injection (PEG-IFN-SA) and Ribavirin（RBV） in the treatment of Chronic hepatitis C who have not been previously treated with Interferon(IFN) by exploring the dose-effect relationship, while identity the optimal dose for phase Ⅲ study. In addition, population pharmacokinetic method is adopted to assess the pharmacokinetic behavior, individuals / intra-individual variability, and the possible factors for further study.
This study is to confirm the potential effects and assess the safety of a new bio-product Pegylated Recombinant Consensus Interferon Variant Solution for Injection (PEG-IFN-SA) and Ribavirin（RBV） in the treatment of Chronic hepatitis C who have not been previously treated with Interferon.
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.
This study is designed to provide a preliminary assessment of the safety and effectiveness of the combination of PPI-668, BI 207127 and faldaprevir, with or without ribavirin, in the treatment of chronic hepatitis C virus infection.
Pharmacokinetics of Buprenorphine and Naloxone in Subjects with Mild to Severe Hepatic Impairment and in HCV-Seropositive Subjects, and in Healthy Volunteers.
A Phase 2 Study to Evaluate the Safety, Efficacy, Pharmacokinetics, and Pharmacodynamics of VX-135 and Daclatasvir in Treatment-Naïve Adult Subjects With Genotype 1 Chronic Hepatitis C
The purpose of this study is to evaluate the antiviral efficacy, safety, tolerability of combination therapy with sofosbuvir (SOF) containing regimens for the treatment of chronic hepatitis C virus (HCV) infection.
This is a Phase 1 Open-Label, Parallel-Group, Single-Dose Study to evaluate the Pharmacokinetics of GS-5816 in subjects with normal hepatic function and moderate or severe hepatic impairment.
The purpose of the study is to determine the safety, pharmacokinetics and efficacy of orally administered VX-135 with ribavirin in treatment naive subjects with chronic hepatitis C infection.
