Active clinical trials for "Hepatitis B"

This exploratory study is designed to determine the early viral kinetic profile during treatment with telbivudine or entecavir at multiple time points over 12 weeks.

The purpose of this study is to evaluate the effectiveness of entecavir plus adefovir combination therapy versus entecavir monotherapy or therapy with adefovir plus lamivudine

The purpose of this clinical study is to determine the appropriate doses of entecavir to use in children and adolescents. Safety, tolerability and efficacy will also be studied

Since a proportion of patients with Acute Viral Hepatitis-B develop severe hepatitis and fulminant hepatic failure, it is logical to believe that a rapid reduction in the HBV DNA levels by using antiviral agents could result in a less intense host response against the hepatitis B virus. However, the experience with lamivudine treatment of immunocompetent patients with AVH-B is limited.The aim of the present study was to evaluate the efficacy, utility and safety of lamivudine in treating immunocompetent patients with AVH-B.

This study is SAD(Single Ascending Dose)/MAD(Multiple Ascending Dose) study to Explore the Tolerability, Safety and Pharmacokinetics/Pharmacodynamics of GC1102 (Recombinant Hepatitis B Human Immunoglobulin) in Chronic Hepatitis B Patients.

This is a multicenter, double blind, active-controlled, randomized, parallel group study to demonstrate the anti-viral activity and safety of Baracle Tab. and Baraclude Tab. for patients with HBeAg Chronic Hepatitis B. The subject will receive two tablets daily for 48 days.

The relevant data will be prospectively collected included patient demographics, clinical, all laboratory variables including virological tests, genotyping by direct sequencing, abdominal ultrasound, and upper gastrointestinal (GI) endoscopy. Trans jugular liver biopsy (TJLB) and hepatic venous pressure gradient (HVPG) will be done in patients when it was not evident whether the underlying liver disease was chronic based on clinical, biochemical, radiological investigations, and upper GI endoscopy. Severity of the liver disease will be assessed by Child-Turcotte Pugh score (CTP) and model for end stage liver disease (MELD) score.

This study is a multi-center, randomized, prospective open-label study to assess the efficacy and safety of combination of peginterferon alfa-2b (40kD, Y-shape) and GM-CSF in interferon-naïve chronic hepatitis B patients with HBeAg positive. Patients were randomized to one of the 2 groups to receive different antiviral treatment.

This trial is to assess the efficacy and safety of Polyethylene Glycol thymosin alpha1 (PEG-Tα1), a new long immunomodulator (Category 1.1 of Chemical Drugs) being developed from Hansoh Pharmaceutical of China, in combination with adefovir in HBeAg-positive patients with chronic hepatitis B.

REP 2139-Ca is nucleic acid polymer. Nucleic acid polymers have been previously shown to clear serum hepatitis B virus surface antigen (HBsAg) both preclinically (in duck HBV infected ducks) and in human patients and to act synergistically with immunotherapeutic agents such as pegylated interferon-alpha 2a or thymosin alpha-1 to restore host immunological control of HBV infection. HBsAg is an essential component of the hepatitis D virus (HDV), therefore the direct action of REP 2139-Ca in removing serum HBsAg and its synergistic effect with pegylated interferon-alpha 2a is expected to have a significant antiviral effect against HDV infection. This study will examine the safety and efficacy of REP 2139-Ca therapy when used in combination with pegylated interferon alpha-2a in patients with HBV / HDV co-infection. The primary hypothesis to be tested is that this combined dosing regimen is safe and well tolerated in patients with HBV / HDV co-infection which will be assessed by examining the number of patients with adverse events (including reported symptoms and laboratory abnormalities). The secondary hypothesis to be tested is that this combined dosing regimen will have an antiviral effect against HBV / HDV co-infection in these patients which will be assessed by examining the following outcomes: The number of patients with reductions in serum HBsAg. The number of patients with reductions in serum HDAg and HDV RNA The number of patients that experience a sustained antiviral response after treatment is stopped (reductions in serum HBV DNA and HDV RNA). The secondary hypothesis to be tested is that this combination approach can have an effective
