Active clinical trials for "Hepatitis A"

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.

To determine the efficacy and safety S-adenosyl-l-methionine in alcoholic hepatitis with cholestasis.

This is an evaluation of adenosine methionine for treatment of chronic hepatitis b patients with cholestasis efficacy and safety of multicenter, randomized, open label clinical trial.

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

This is a prospective randomized, open-label, phase IV clinical trial to learn the effects, good and/or bad, of discontinuing or continuing nucleos(t)ide analogue (NA) treatment for 72 weeks in participants with chronic hepatitis B infection whose immune system is controlling the amount of virus levels in the blood for at least 12 months of NA therapy. About 66 adult men and women will participate in this study from University Health Network which includes the Toronto Western Hospital for about 72 weeks.

This study proposes to compare the effect of 48 weeks exposure to pegylated interferon alpha vs. nucleoside analogue (NA) on hepatitis B e antigen (HBeAg) seroconversion and HBsAg levels in nucleoside analogue controlled HBeAg-positive chronic hepatitis B (CHB) patients who have an undetectable hepatitis B virus (HBV) viral load at least 1 years.

The term Acute on chronic liver failure (ACLF) describes a clinical entity characterized by an acute and rapid deterioration of liver function in a patient with previously well-compensated liver disease owing to the effects of a precipitating event. In this condition two insults act simultaneously, one being the preexisting liver injury (chronic liver disease) and the other acute injury which is responsible for the acute decompensation. HEV being a major factor responsible for this clinical entity and has a very high mortality rate. Ribavirin being a safe drug and has been shown to inhibit the replication of HEV, can be an important drug in the treatment of these patients. Therefore the present study is designed to study the impact of Ribavirin in reducing the mortality due to HEV related ACLF.

The purpose of this open-label study is to assess the safety, antiviral activity, and pharmacokinetics of 9 subcutaneous injections of miravirsen monotherapy (5 weekly doses over 5 weeks, followed by a further 4 doses once every other week over 7 weeks) over a total of 12 weeks of treatment. The subjects enrolled in this study are chronically infected with HCV genotype 1 and are null responders to treatment with peg IFNα/RBV therapy.

A maximally tolerated dose of ribavirin can be defined in each patient with ESRD undergoing hemodialysis. Patients with Chronic Hepatitis C Virus (HCV)and End-Stage Renal Disease (ESRD)undergoing hemodialysis will be able to tolerate and remain on treatment with peginterferon alfa-2b, the maximally tolerated dose of ribavirin and boceprevir. A significant percentage of patients with chronic HCV and ESRD undergoing hemodialysis can achieve rapid virologic response (RVR), extended virologic response (eRVR) and sustained virologic response (SVR) when treated with peginterferon alfa-2b, the maximally tolerated dose of ribavirin and boceprevir.
