Active clinical trials for "Hepatitis B"

To assess whether PEG-INF (Peglyated - interferon) Add-on therapy in patients of CHB who have achieved a maintained viral suppression (HBV DNA PCR( polymerase chain reaction) <200 for last 3-6 month) with NA's can result in increased rate of HBV infection eradication (HbsAg is undetectable by serological blood testing with or without seroconversion to HBs antibody).

The purpose of this study is to demonstrate that long-term treatment (up to six years) with telbivudine or telbivudine plus adefovir results in the regression in liver inflammation and fibrosis/cirrhosis.

Compared to TDF, peginterferon alfa 2a may has more therapeutic efficacy in hepatitis B surface antigen or e antigen seroconversion and anti-tumor occurrence in chronic hepatitis b patients. We design this study to compare the effectiveness and safety between the combination therapy of TDF and peg-IFN with TDF alone in NAs experienced patients with HBV related liver fibrosis. Especially the improvement of liver fibrosis and the occurrence of long-term end-stage liver disease such as cirrhosis, liver cancer, etc.

This study is a single-center, randomized, prospective, open-label Phase 2 Clinical trial to evaluate efficacy and safety of ETV and TQ-A3334 combinated with/without inhibitor of TQ-B2450 versus ETV alone in chronic hepatitis B patients. Patients were randomized to one of 3 different antiviral treatment.

This study is an open-label, randomized, single dose, crossover study to evaluate the pharmacokinetics, safety and tolerability of CKD-388 in healthy subjects

This is an open label, randomized, multi-center, comparative study. Subjects will be screened prior to study entry to establish eligibility. 100 Subjects who meet all the selection criteria will be randomly assigned 1:1:1:1:1 to (A) QL007 100 mg QD+ Tenofovir dipirofurate fumarate （TDF）300 mg QD, (B) QL007 200 mg QD+ TDF 300 mg QD, (C) QL007 400 mg QD+ TDF 300 mg QD, (D) QL007 200 mg BID+ TDF 300 mg QD, (E) TDF 300 mg QD. The purpose of this study was to evaluate the efficacy and safety of QL-007 in combination with TDF in HBeAg positive patients with chronic hepatitis b, and to recommend a reasonable regimen for phase III study.

A multiple-center, open-label, Phase II clinical trial to evaluate the safety and the efficacy of HLX10 in chronic hepatitis B patients.

Adefovir add-on therapy is superior to switching to adefovir monotherapy or entecavir 1mg monotherapy for chronic hepatitis B (CHB) patients with lamivudine resistance (LAM-R) Long-term adefovir add-on therapy was effective for viral suppression. However, the economic burden for such dual antiviral therapy is heavy because of infinite treatment. Tenofovir disoproxil fumarate (TDF) is a potent antiviral agent. TDF demonstrated potent antiviral efficacy in a subset of lamivudine experienced HBeAg-positive patients. TDF is also superior to ADV in HBeAg-negative and HBeAg-positive treatment-naive patients. Theoretically, TDF can replace LAM/ADV when viral suppression has been achieved by LAM/ADV combination treatment in LAM-R CHB patients.

The purpose of the study is to evaluate the effects and safety of Adefovir Dipivoxil plus polyene phosphatidylcholine compared to Adefovir Dipivoxil alone in patients with chronic hepatitis B.

The purpose of this study is to verify the effectiveness and safety of medical ozone therapy system in treatment of chronic hepatitis B.
