Active clinical trials for "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.

To evaluate the antiviral activity of 3 days of BZF961. To determine safety and tolerability of BZF961 in HCV patients. To evaluate pharmacokinetics of BZF961 in HCV patients.

To demonstrate the effectiveness of DCV 3DAA fixed dose regimen in treatment naive and treatment experienced non-cirrhotic subjects

The purpose of this study is to determine whether treatment with Daclatasvir/Asunaprevir/BMS-791325, with or without ribavirin, for 8, 6, or 4 weeks is feasible for the treatment of genotype 1a chronic hepatitis C in patients without cirrhosis.

The primary purpose of this study is to evaluate the pharmacodynamic (i.e. hepatitis C virus (HCV) viral load), pharmacokinetic and safety profiles between two treatment groups receiving different doses of DEB025 in combination with ribavirin (RBV) during the first 12 weeks treatment in chronic hepatitis C genotype (GT)-2 and GT-3 patients who had previously failed interferon therapy or were intolerant or unable to take interferon.

The aim of this study is to explore the efficacy and safety of boceprevir -based triple therapy to rescue HCV genotype 1 (HCV GT1)/HBV dually infected patients refractory to previous peginterferon (PEG-IFN) plus ribavirin (RBV) combination therapy.

To evaluate the safety, tolerability and immunogenicity of VGX-6150 as second-line therapy in chronic hepatitis C patients

This is an open label, dose ranging, phase1a/1b clinical trial to study the safety, Pharmacokinetics and Pharmacodynamics of Peglamda 60, 120, 180 and 240 mcg in healthy volunteers and antiviral activity of once weekly Peglamda administration in combination with daily Ribavirin in Hepatitis C naive patients up to 4 weeks period. The objective of the study to establish safety, PK/PD data on healthy subjects and preliminary efficacy and safety in Hepatitis C naive patients.

This parallel group, open label study will evaluate the safety and efficacy of Pegasys (peginterferon alfa-2a) versus untreated control in children (age 3 years to <18 years at baseline) with HBeAg positive chronic hepatitis B. Children without advanced fibrosis and without cirrhosis will be randomized 2:1 to treatment Group A, receiving Pegasys 45-180 mcg subcutaneously weekly for 48 weeks, or to the untreated control Group B. Children with advanced fibrosis will be assigned to treatment group C and receive 48 weeks of treatment with Pegasys. Children in the untreated control Group B who have not experienced seroconversion 48 weeks after randomization may enter the Switch Arm to receive 48 weeks of Pegasys treatment. This offer will be available for 1 year following 48 weeks from randomization. Anticipated time on study treatment is 48 weeks. All subjects will be followed up for 5 years after the end of treatment (A,C,Switch)/principal observation (B) period.
