Active clinical trials for "Hepatitis, Chronic"

The study objective is to evaluate the safety and effectiveness of different doses of Metacavir Enteric-coated Capsules in treatment of chronic hepatitis B,as well as to find an appropriate clinical dosage by comparing the effect of different doses of treatment,in order to provide references of clinical trial of the next phase.

Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry that include two hydrophobes and one hydrogen bond acceptor. Therapy with Ezetimibe may lead to decline in hepatitis D virus levels. The aim of the study is to evaluate the utility of Ezetimibe in patients with chronic HDV infection

This is a nonrandomized, open-label, no-control, dose-escalation Phase 1b trial in 18 patients with chronic HBV infection to determine the safety, preliminary efficacy, and pharmacokinetics (PK) of QL-007 after administration over 28 days of multiple oral doses in a fasted state at the following planned dose levels: 200 mg/day (100 mg two times a day (BID)), 400 mg/day (200 mg BID), then 600 mg once daily (QD), with 6 patients for each cohort.

Chronic Hepatitis B is the most common cause of chronic viral liver disease worldwide afflicting 350 million persons, leading to significant morbidity and mortality due to liver disease and HCC in 20-40% of infected persons. With the advent of nucleoside analogues, this rescued patients with significant risk of disease progression, but in most circumstances, therapy was needed long term as HBsAg seroclearance was an uncommon occurrence, and stopping therapy was associated with relapse of disease and hepatitis B flares. The use of pegylated interferons showed increased HBeAg seroconversion and HBsAg seroclearance rates compared to nucleoside analogues , however combination nucleos(t)ide analogue therapy has been quite disappointing. However a recent showed that the combination of telbivudine and tenofovir in a response guided therapy design, had a remarkable 6% HBsAg seroclearance at week 52 in patients. Such results require further confirmation. There is currently an unmet need for the large number of patients on long term nucleoside analogue therapy who have not achieved HBeAg seroconversion or HBsAg seroclearance. Such patients are seeking alternatives to long term therapy hence an exploration of other therapeutic strategies is attractive. An additional benefit of telbivudine has been the surprising improvement in renal function and this study seeks to examine whether this can improve the renal impairment that may be seen with tenofovir. Our study proposes to examine if the combination of tenofovir and telbivudine can improve endpoints. Patients fulfilling inclusion and exclusion criteria will be randomized to tenofovir or tenofovir and telbivudine (1:1 ratio). The primary endpoint will be a qHBsAg reduction of >1log at week 96, which may predict future HBsAg seroclearance, which is also a secondary endpoint. An additional primary endpoint is increase in eGFR in the combination arm compared to the monotherapy arm. The study aims to enroll 146 patients randomized 1:1 ratio (73:73) patients. Multivariate analysis will be performed of baseline and on-treatment factors that predict the primary outcome.

This is a randomized, double-blinded, placebo-controlled, phase IIa study to evaluate safety and efficacy of TQ-A3334 combined with entecavir in the untreated or HBV DNA negative subjects with Chronic Hepatitis B.

To compare the efficacy of nucleoside analogues （HA） alone and plasma purification +HA in reducing HBV viral load.

The purpose of this study is to provide theoretical and real world evidence for the optimization of antiviral treatment by IFN combined with Nucleosides analog in HBeAg positive chronic hepatitis B patients aged 1-16 years，so that the functional cure could be achieved in the greatest extent in pediatric patients

The aim of the present trial is to evaluate whether the conversion of immunosuppression from tacrolimus to cyclosporine A induces changes in (i) hepatitis C-virus load, (ii) parameters of hepatic function and (iii) parameters of glucose tolerance in hepatitis C-positive renal transplant recipients.

The host immunity has been generally recognized as the main factors to determine the outcome of chronic hepatitis B virus (HBV) infection; however, previous studies have shown that HBV-specific T cell and B cell function are exhausted in chronic hepatitis B (CHB) patients. Recently, It is suggested that hepatitis B surface antigen (HBsAg) may play a key role in the immune tolerance or immune exhaustion. Anti-HBV immune responses are partially recovered when patients achieved hepatitis B e antigen (HBeAg) seroconversion during antiviral therapy, and can be nearly recovered during HBsAg seroconversion. However, it is still difficult to achieve the ideal terminal, HBsAg seroconversion. For this reason, immunotherapy would be helpful to enhance the anti-HBV immunity and acquire higher HBsAg seroconversion. Here, the investigators propose a hypothesis that hepatitis B immune globin (HBIG)+granulocyte-macrophage colony-stimulating factor (GM-CSF)+HBV vaccine can enhance anti-HBV immune responses and improve HBsAg seroconversion in CHB patients who has achieved HBeAg seroconversion using nucleoside analogues treatment.

To prove that a study drug is noninferior to a control drug with a proportion of subjects who showed HBV DNA undetected (less than 400 copies/mL (69 IU/mL)) at the 48th week after 48-week administration of Besifovir 150 mg, or Tenofovir 300 mg as a control drug to chronic hepatitis B patients
