Active clinical trials for "Hepatitis A"

Phase 2a study designed to assess the safety, efficacy, and pharmacokinetics of Faldaprevir and TD-6450 in combination with Ribavirin for a 12-week treatment duration in treatment-naïve participants with genotype 4 hepatitis C virus (HCV) infection.

NAPs have been previously shown to clear serum hepatitis B virus surface antigen (HBsAg) both preclinically (in duck HBV infected ducks) and in human patients. REP 2139-Ca mediated HBsAg clearance acts synergistically with immunotherapeutic agent pegylated interferon-alpha 2a to restore host immunological control of HBV infection. REP 2165 is a version of REP 2139 which has been shown preclinically to retain antiviral activity with lower accumulation in the liver. Both REP 2139 and REP 2165 used in this protocol are formulated as magnesium chelate complexes, which improve their administration tolerability. This open label, randomized and controlled study will examine the safety and efficacy of REP 2139-Mg and REP 2165-Mg therapy in patients with HBeAg negative chronic hepatitis B when used in combination with tenofovir disoproxil fumarate and pegylated interferon alpha-2a.

The purpose of this study is to assess the safety and efficacy of 12 weeks of treatment of ABT-493/ABT-530 (glecaprevir/pibrentasvir) in adults who are post primary orthotopic liver or renal transplant with chronic hepatitis C virus (HCV) infection.

An open label, multicentre, international pilot study of paritaprevir/ritonavir, ombitasvir, dasabuvir with or without ribavirin or glecaprevir/pibrentasvir for people with recently acquired hepatitis C virus infection with or without HIV co-infection.

The purpose of this study is to evaluate the effect of response to treatment by evaluating the percentage of subjects achieving a 12-week sustained virologic response (SVR12) after 12 weeks of treatment with ABT-493/ABT-530 and to evaluate the safety of the regimen in participants with chronic hepatitis C virus (HCV) genotype (GT) 4, 5, or 6 infection.

Background: - Chronic hepatitis D is a liver disease caused by the hepatitis D virus (HDV). It can be severe and progressive. Most people with hepatitis D will develop scarring and damage to the liver. There is no FDA approved drug to treat chronic hepatitis D. Researchers want to know if the drugs lonafarnib and ritonavir can help people with chronic hepatitis D. Objective: - To find out if treatment of hepatitis D with lonafarnib and ritonavir is safe and effective. Eligibility: - People 18 years of age and older with chronic hepatitis D. They must not have HIV or other major illnesses. Design: Participants will be screened with medical history, physical exams, and blood tests. Participants will have 24 weeks of treatment. They will then have 24 weeks of follow-up. Participants will be in 1 of 6 treatment groups. Those in each group will receive different doses of the study drugs. Some groups will start with placebo but will receive treatment after 3 months of placebo. Participants will also take drugs to treat hepatitis B. Participants will have many visits. These will include: One three-day stay at the Clinical Center Physical exams EKG: small sticky patches will be put on the chest, arms, and legs to trace heart rhythm Ultrasounds of the abdomen Urine and blood tests Stool samples Eye exams Evaluations by a reproductive endocrinologist (women) or urologist (men). Men may provide a sperm sample (optional).

This is an open-label, single arm, multicenter, pilot-study to compare the efficacy and safety of LDV/SOF fixed dose combination (FDC) in subjects with acute genotype 1 HCV infection. A total of 20 subjects will be assigned to receive LDV/SOF FDC tablet (LDV 90 mg/SOF 400 mg/) once daily for 6 weeks.Patients will be followed up for 24 weeks.

The study is aimed to evaluate the additional role of ciprofloxacin therapy in severe alcoholic hepatitis combined to prednisolone therapy in an open-label placebo controlled manner.

The purpose of this study is to evaluate the efficacy of 6 or 8 weeks of treatment regimen containing simeprevir (SMV), daclatasvir (DCV) and sofosbuvir (SOF) in treatment-naive (not having received treatment with any approved or investigational drug) participants with chronic hepatitis (inflammation of the liver) C virus (HCV) genotype 1 infection with early stages of liver fibrosis or with cirrhosis.

Patients with acute hepatitis C virus (HCV) infection usually become chronicity if viremia persists after 6 months of infection. The result of using pegylated interferon plus ribavirin combination therapy upon these patients remains to be explored
