Active clinical trials for "Hepatitis, Chronic"

The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without sofosbuvir (SOF) and ribavirin (RBV) in DAA treatment-experienced adults with Genotype 1 Chronic Hepatitis C Virus infection. This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.

The study is an open-label, randomized, comparative, multicenter clinical trial. The purpose of this study is to assess the efficacy of ABX203, a new chronic hepatitis B therapeutic vaccine administered as an adjunct therapy to nucleos(t)ide analogs (NUCs), in maintaining control of Hepatitis B disease after cessation of treatment with NUCs in subjects with HBeAg negative chronic Hepatitis B.

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.

The purpose of this study was to evaluate the safety and efficacy of ombitasvir/ paritaprevir/ ritonavir and dasabuvir in adults with genotype 1b chronic hepatitis C virus (HCV) infection and cirrhosis.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.

The purpose of this study is to evaluate the effectiveness of telaprevir administered twice daily versus every 8 hours in combination with Peg-IFN-alfa-2a and ribavirin in treatment-naïve participants with chronic HCV genotype 1 infection.

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.

This study will evaluate the efficacy and safety of MP-424 with IFN beta and RBV in patients with genotype 1/2 hepatitis C, who are treatment-naïve or have received its treatment before.

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

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.
