Active clinical trials for "Hepatitis, Chronic"

This study will provide a rationale for switch from lamivudine plus adefovir to tenofovir monotherapy in Lamivudine plus Adefovir Treated Lamivudine-resistant chronic hepatitis B patients with Undetectable Hepatitis B Virus DNA

The purpose of this study is to evaluate the safety and antiviral activity 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) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1b (HCV GT1b) infection without cirrhosis.

Parts A and B of this study are designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir and simeprevir when administered in combination with ribavirin (RBV) for 12 weeks in treatment-naïve, Genotype (GT) 1b, 4 and 6 hepatitic C virus (HCV)-infected participants. Part C of this study is designed to evaluate the safety, tolerability, efficacy and pharmacokinetic profiles of samatasvir, simeprevir, TMC647055 and ritonavir (RTV) when administered in combination with or without RBV for 12 weeks in treatment-naïve or interferon/RBV-treatment relapsed, GT 1a and 1b HCV-infected participants.

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

Patients with spontaneous decline of HBV DNA were non-randomly assigned to accept peginterferon alfa-2a or entecavir therapy, or didn't accept any antiviral regiment.

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.

The purpose of this study is to investigate the efficacy and safety of medical ozone in treatment of chronic hepatitis B patients.

The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection.

GSK2878175 is a site IV NS5B non-nucleoside inhibitor (NNI) being developed for the treatment of chronic hepatitis C virus (HCV) infection. The purpose of this study is to investigate the effects of GSK2878175, at different doses in men and women infected with chronic hepatitis C virus. The study will investigate how much of the drug gets into the blood stream and how long the body takes to get rid of it. The study will also investigate if GSK2878175 has any important side effects. The study will also measure what effect GSK2878175 has on the hepatitis C virus infection after taking the study medication for 2 days. Approximately 44 people will take part in this study. Depending on the type of chronic hepatitis C infection a subject will be enrolled into 1 of 4 groups randomly. Each group will participate in one dosing session. One dosing session consists of GSK2878175 or a placebo (sugar pill) given once per day for 2 days. Group A, B, and C is made up of 8 participants per group. In each of these groups 6 participants will receive GSK2878175 and 2 participants will receive placebo. Group D is made up of 20 participants. 15 participants will receive GSK2878175 and 5 participants will receive placebo. The treatment groups will be dosed in sequence. Group A will be the first to take the study medication, then Group B, and so on. The plan is to dose subjects in Group A with 10 mg, Group B with 30 mg, Group C with 60 mg, and Group D with 60 mg of GSK2878175 or placebo. The next treatment group's actual dose will be decided after looking at the results from the previous group. The doses may therefore be higher or lower than planned depending on the previous group's results. The number of participants enrolled in the next group may also change depending on the results from the previous group.

The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.
