Active clinical trials for "Hepatitis A"

This is a multi-part study to evaluate the safety, tolerability, and pharmacokinetics (PK) of uprifosbuvir (MK-3682/IDX21437) in healthy participants and in participants infected with Hepatitis C virus (HCV) genotype (GT)1-GT6. The effect of food on the PK of uprifosbuvir will be evaluated. The antiviral activity of uprifosbuvir will also be assessed in HCV-infected participants.

The purpose of this study is to evaluate the safety and efficacy of Entecavir maleate tablets in Chinese patients with hepatitis B

Patients with Chronic Hepatitis B on long term oral antiviral therapy have to continue treatment indefinitely unless they achieve HBeAg seroconversion or HBsAg seroclearance, when therapy can be stopped. While HBeAg seroconversion is a more achievable endpoint, only 20-25% of patients develop this after one year of oral antiviral therapy. HBsAg seroclearance is universally infrequent. Strategies to improve these endpoints such as combination oral antiviral therapy have not been generally successful and recently studies have examined the possibility of switching or adding peginterferon therapy. However these have not been tested adequately in the group of patients that have been on long term oral antiviral therapy. Consequently this study was conceived to evaluate whether switching or adding peginterferon compared to continuing oral antiviral therapy are more efficacious strategies. HBeAg positive and HBeAg negative patients (n=310)will be randomised to continue oral antiviral therapy, switch or add pegylated interferon for 48 weeks in a ratio of 1:2:2 respectively. The study endpoints are HBsAg seroclearance, reduction of qHBsAg >1 log, qHBsAg<200 IU/ml, HBeAg loss and seroconversion, and HBV DNA suppression, all at week 72.

Response-guided triple-therapy with boceprevir (BOC) in combination with pegylated interferon (PEGIFN) and ribavirin (RBV) is the current standard of care for HIV-negative patients infected with hepatitis C genotype (HCV-GT) 1. In contrast, in HIV-positive patients, a fixed treatment duration of 48 weeks is used. The aim of this study is to assess efficacy and safety of response-guided triple-therapy with BOC in combination with PEGIFN and RBV in HIV-positive patients. Thus, treatment duration will be individualized based on HCV-RNA negativity at treatment week 8 (W8). All patients will receive 4 weeks of PEGIFN/RBV lead-in. Patients with undetectable HCV-RNA at W8 will be treated with 24 weeks of BOC/PEGIFN/RBV triple-therapy resulting in a total treatment duration of 28 weeks, while patients with detectable HCV-RNA at W8 will receive 44 weeks of BOC/PEGIFN/RBV triple-therapy and a total treatment duration of 48 weeks.

PPI-383 is an antiviral agent (an inhibitor of the hepatitis C virus NS5B polymerase) that is being developed as a potential treatment for hepatitis C virus infection. This study is being done to assess the dose-related safety and tolerance of PPI-383 when given to healthy volunteers for up to 5 days (Part I of the study) and to hepatitis C patients for up to 3 days (Part II). In addition, the study will assess how much PPI-383 is absorbed into the bloodstream. In Part II, the dose-related effect of PPI-383 on the amount of hepatitis C virus in patients' bloodstream (serum HCV RNA levels) also will be assessed.

A study of the efficacy and safety of the combination of daclatasvir and sofosbuvir in the treatment of hepatitis C virus and HIV coinfection.

The purpose of the study is to assess how feasible it is to treat and prevent the transmission of Hepatitis C in the prison setting to achieve substantial reductions in the incidence and prevalence of Hepatitis C. It is hypothesised that a rapid scale-up of Hepatitis C Virus (HCV) treatment with interferon-free Direct Acting Anti-virals (DAAs) in prison inmates will achieve a >50% reduction in the incidence of HCV infection over a two year period in the prison setting.

The purpose of this study is to evaluate the safety and antiviral effect of ABT-450/r and ABT-530 coadministered with and without Ribavirin in adults with genotype 3 HCV infection.

Patient presenting with upper GI bleed in ILBS (Institute of Liver and Biliary Sciences) emergency admitted to ICU (Intensive Care Unit) or shifted from ward to ICU (Intensive Care Unit) in view of upper GI bleed randomized to two groups GROUP A : 110 Patients will receive standard care + NAC infusion for 72 hours GROUP B : 110 Patients will receive standard care only NAC will be given at following rate : Initial loading of 150 mg/kg/hr over 1 hour Followed by 12.5mg/kg/hr for 4 hrs Then continuous infusion of 6.25 mg/kg for the remaining 67 hrs

This is a Phase 3, randomized, open-label, multicenter study, enrolling non-cirrhotic and cirrhotic subjects. The purpose of this study is to evaluate the efficacy and safety of ABT-450/r/ABT-267 co-administered with weight-based RBV for 12 or 16 weeks in adult chronic HCV genotype 2-infected treatment-naïve and interferon (IFN) treatment-experienced subjects with and without compensated cirrhosis.
