Active clinical trials for "Hepatitis B, Chronic"

This is a multi-center phase 3, open-label, parallel-group study designed to evaluate the efficacy, safety and pharmacokinetics of adefovir dipivoxil liquid suspension in patients with chronic hepatitis B and varying degrees of renal impairment.

This trial is being done to see if the investigational drug, LdT (Telbivudine), is safe and effective in the treatment of hepatitis B infection. In addition to this, we will be looking at the comparison of the effects (good and bad) of LdT and lamivudine.

This study is being conducted to compare the safety and effectiveness of switching treatment from lamivudine to telbivudine (LdT) against continued lamivudine treatment. Results from patients who were taking lamivudine and then switched to telbivudine will be compared with the results from patients who continued on lamivudine alone.

The purpose of this study was to determine the safety and anti-hepatitis B virus (-HBV) activity of ACH-126,443 in comparison to lamivudine or placebo in treatment-naive adults with chronic hepatitis B infection.

The purpose of this clinical research study is to assess the safety and effectiveness of switching to entecavir compared to continued lamivudine in patients with chronic hepatitis B.

Part 1 is a randomized, double-blind, placebo-controlled study. It will assess the safety, tolerability, and pharmacokinetics of single and multiple orally administered doses of EDP-514 in healthy adult subjects. Part 2 is randomized, double -blind, placebo-controlled study including subjects with Hepatitis B Virus. It will assess the safety, tolerability, pharmacokinetics and antiviral activity of 28 Days of orally administered doses of EDP-514 in nucleos(t)ide reverse transcriptase inhibitor (NUC)-Suppressed Patients with Chronic Hepatitis B Virus Infection

Renal impairment is common in patients with chronic hepatitis B infection. For those taking nucleotide analogues, renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. In this prospective study, consecutive CHB patients on combined lamivudine (LAM)+ADV/TDF are switched to LdT+ADV/TDF at recruitment and are followed up for 24 months. Estimated glomerular filtration rate (eGFR) is calculated with the Modification of Diet in Renal Disease (MDRD) equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers are investigated in cultured renal tubular epithelial cell line HK-2.

The Safety, Antiviral Activity, and pharmacokinetics of Morphothiadine Mesilate Capsules/Ritonavir Tablets in Patients with Chronic Hepatitis B

The main purpose of this study is to evaluate efficacy of 24 weeks of study treatment, in terms of changes in hepatitis B surface antigen (HBsAg) levels.

This is a Phase4, multicenter, open-label, randomized study to demonstrate that the Tenolid Tab switching group is non-inferior to the virologic suppression effect compared to the Viread Tab continuous administration group and evaluate the safety of Tenolid Tab. This clinical trial was conducted on patients who were taking Viread Tab as monotherapy for more than 48 weeks for chronic hepatitis B. At the time of screening(Visit 1), information on factors related to medical history and prognosis including Viread Tab administration were collected retrospectively from the subjects who voluntarily signed the informed consent form (ICF). Only subjects who are determined to be suitable for the study eligibility(inclusion/exclusion) criteria as a result of the screening evaluations are randomized in a 1:1 ratio to one of the two groups at the baseline. Subjects will receive investigational product start on the next day of randomization for 48 weeks. Subjects will visit to the study site on 12, 24, 36, 24 weeks after starting dosing investigational product and evaluated for effectiveness of virologic suppression and safety.
