Active clinical trials for "Hepatitis A"

To evaluate safety and tolerability of lambda over a 48-week treatment period in HDV patients.

To determine the efficacy and safety of Harvoni in treatment-naïve alcoholic subjects with Genotype 1 HCV infection

This study will explore the relationship of different DEB025 doses in combination with RBV to pharmacokinetic, pharmacodynamic (i.e. viral load reduction) and safety profiles in chronic hepatitis C GT 2 and 3 treatment naïve patients.

This study is being done to evaluate the efficacy and safety of the drug combination grazoprevir (GZR; MK-5172) + elbasvir (EBR; MK-8742) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1, 4, or 6 infection and who have cirrhosis and Child-Pugh (CP) score 7-9 moderate hepatic insufficiency (CP-B). The primary hypothesis is that the percentage of HCV-infected participants with hepatic insufficiency (the CP-B population) achieving sustained viral response (SVR) 12 weeks after the end of all treatment (SVR12) will be greater than 60%. Additionally, ten non-cirrhotic (NC) HCV-infected GT1 participants will also be given GZR + EBR at the beginning of the study; this will be done for the purpose of collecting plasma pharmacokinetic (PK) data in HCV GT1-infected participants who do not have hepatic insufficiency.

This is a 2-part study. The purpose of Part A is to assess the efficacy and safety of grazoprevir (MK-5172) 100 mg in combination with elbasvir (MK-8742) 50 mg for 12 weeks in the treatment of chronic HCV GT1, GT4, or GT6 infection in treatment-naïve participants who are on opiate substitution therapy (OST). The primary hypothesis is that the percentage of participants who receive grazoprevir/elbasvir fixed-dose combination (FDC) in the Immediate Treatment Arm and achieve a Sustained Virologic Response 12 weeks after the end of all study therapy (SVR12) will be superior to 67%. In addition, participants who received at least 1 dose of grazoprevir/elbasvir in Part A will be eligible to participate in Part B, which is a 3-year observational follow-up.

This is an efficacy and safety study of grazoprevir (MK-5172) in combination with elbasvir (MK-8742) with or without ribavirin (RBV) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1, 4, or 6 infections who have failed prior therapy with pegylated interferon and RBV. The primary study hypothesis is that in at least one of the study arms, the percentage of participants achieving sustained viral response 12 weeks after the end of all study treatment (SVR12) will be superior to 58%.

The purpose of this study is to compare the safety and tolerability of ascending doses of SB 9200 given for up to 14 days to subjects with chronic Hepatitis C infection.

To evaluate the effect of an intensive enteral nutrition (compared to clinical routine) in association with corticosteroïds in patients with severe acute alcoholic hepatitis.

Background: The HBsAg clearance rate in interferon-treated responders is significantly higher than that in lamivudine-treated responders, implying immune control is the key to HBsAg clearance. There is a good chance to further increase the cure rate if the investigators can enhance the HBV-specific immune response when the HBsAg level already comes to a low level. Hypothesis: HBsAg-based vaccine can enhance HBsAg clearance in chronic hepatitis B patients whose HBsAg already <=2000 IU/ml. Patients and methods: This pilot study will enroll 20 chronic hepatitis B patients with HBsAg ≦2000 IU/ml, no hepatic decompensation, no HIV coinfection, nor clinical immunodeficiency. Engerix-B vaccine (20μg for <20 years old and 40 μg for ≥ 20 years old) will be given every 2 months for one year. HBsAg quantification, anti-HBs, and HBV DNA will be surveyed regularly before each dose during the treatment period and every 3 months for another year following the last dose. Viral and cellular factors will be studied to discover determinants affecting HBsAg clearance. Aims To elucidate whether HBsAg-based vaccine can reactivate host immunity to eliminate chronic HBV infection in patients with low titer HBsAg. To delineate the doses to response (HBsAg clearance or decline rate) correlation so as to design a feasible schedule for future clinical trials in a larger group of patients. To discover viral and host factors which can be used as biomarkers for personalized vaccine therapy.

This is a study to evaluate the efficacy and safety of three experimental drugs compared with telaprevir (a licensed product) in people with hepatitis C virus infection who have not had treatment before.
