Active clinical trials for "Hepatitis A"

A total of 100 people with chronic HCV and recent injection drug use or recipients of opioid substitution therapy will be enrolled in 5 countries and 21 study sites. Participants with genotype 1a infection or cirrhosis will receive 12 weeks of open-label paritaprevir/ritonavir/ombitasvir and dasabuvir ("3D"), and twice-daily ribavirin. Participants with genotype 1b infection without cirrhosis will receive 12 weeks of open-label "3D". The study consists of a screening phase (6 weeks), treatment phase (12 weeks) and follow-up phase (96 weeks) to evaluate treatment response and reinfection.

The primary objectives of this study are to evaluate the efficacy, safety and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) for 12 weeks in participants with chronic HCV infection who were coinfected with HIV-1.

This study will evaluate the efficacy, safety, and tolerability of PEGASYS in participants with HBeAg-negative chronic HBV. The anticipated time on study treatment is 48 weeks, and the target sample size is 60 individuals.

The goals of therapy against chronic hepatitis B are to decrease the morbidity and mortality related to chronic HBV infection. Currently available antiviral therapy can suppress viral replication but only a small proportion attain functional cure, which is defined as HBV surface antigen-to-antibody seroconversion. Hepatitis B surface antigen (HBsAg) is a marker of persistent hepatitis B infection. It has been observed that patients who had both hepatitis B and hepatitis C, and who were treated for their hepatitis C with 12 weeks of ledipasvir/sofosbuvir for had a decline in HBsAg levels. This study hypothesizes that a similar decrease would be seen in mono-infected hepatitis B subjects over the course of 12 weeks treatment with ledipasvir/sofosbuvir.

The farnesoid X receptor (FXR) regulates hepatitis B virus replication through the bile acids pathway. EYP001a is a selective, synthetic FXR agonist under development for the treatment of hepatitis B. This Phase 1 study is designed primarily to assess Pharmacokinetics (PK) under fed and fasted conditions, and to assess the safety, tolerability and Pharmacodynamics (PD) of single oral doses of EYP001a in subjects with chronic HBV infection.

The purpose of the study is to study the combination of Sofosbuvir in Combination With Daclatasvir or Simeprevir for 12 Weeks in Non-cirrhotic Subjects Infected With Chronic Hepatitis C Virus (HCV) Genotype 1.

The aim of the study is to determine if treatment for recently acquired hepatitis C infection (with or without HIV coinfection) can be shortened when treating with the interferon-free therapy sofosbuvir/velpatasvir (SOF/VEL). SOF/VEL is a new treatment for hepatitis C called direct acting antiviral which targets the hepatitis C virus replication cycle and has been shown in phase II studies in chronic HCV to be highly effective (SVR12 >95%) when given for 12 weeks. Data has shown that treatment can be shortened when treating recently acquired HCV with interferon containing treatments. It is not known whether treatment with SOF/VEL can be shortened. This study aims to find out if treatment for 6 weeks with open-label SOF/VEL is equivalent to treatment for 12 weeks with SOF/VEL in participants with recently acquired hepatitis C infection. The project is a randomised study where both participants and investigators would not find out the treatment duration of the participants until week 6 of treatment.

There are now several licensed drug treatments for patients with HCV infection. These medications have been shown to be very effective in getting rid of the virus in patients with HCV infection including those with early stages of cirrhosis without complications known as compensated cirrhosis, with a greater than 90% cure rate. At present, there are very little data to show that treating patients with HCV infection and decompensated cirrhosis will give the same effects. However, patients with decompensated cirrhosis as a result of hepatitis B infection who received treatment to control their virus show improvement of their overall liver condition, and the liver complications of many of these patients disappeared. Also, patients with cirrhosis due to excess alcohol and who stopped drinking also showed improvement in liver function and their complications of cirrhosis coming under control. Therefore, treatment of patients with HCV infection and decompensated cirrhosis is expected to show the same positive effects, because the underlying cause of cirrhosis is coming under control. Harvoni is a combination of two direct-acting antivirals (ledipasvir and sofosbuvir) that prevents the hepatitis C virus from copying and multiplying themselves, allowing the body to clear the virus from their systems and be cured of HCV infection. This study is being conducted to find out if treatment with Harvoni will lead to clearance of HCV infection in patients with decompensated cirrhosis giving rise to improvement in liver function, together with improvement of quality of life and survival.

This is a study of the efficacy and safety of peginterferon alfa-2a (Pegasys) in naive, interferon- or lamivudine-pretreated participants with HBeAg-positive chronic HBV. Following 48 weeks treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Alcoholic hepatitis is a syndrome of progressive inflammatory liver injury associated with long-term heavy intake of ethanol. The pathogenesis is not completely understood. Patients who are severely affected present with subacute onset of fever, hepatomegaly, leukocytosis, marked impairment of liver function (e.g., jaundice, coagulopathy), and manifestations of portal hypertension (e.g., ascites, hepatic encephalopathy, variceal hemorrhage). However, milder forms of alcoholic hepatitis often do not cause any symptoms. Alcoholic hepatitis usually persists and progresses to cirrhosis if heavy alcohol use continues. If alcohol use ceases, alcoholic hepatitis resolves slowly over weeks to months, sometimes without permanent sequelae but often with residual cirrhosis. F-652 is a recombinant fusion protein containing human interleukin 22 (IL-22) and human Immunoglobulin G2 (IgG2)-Fc produced in CHO cells in serum-free culture. F-652 under development is intended to treat patients with graft vs host disease (GvHD) after bone marrow transplantation, and acute alcoholic hepatitis (AAH), a severe form of alcoholic liver disease (ALD). Both GvHD and AAH are diseases with unmet medical need. The current investigational new drug (IND) application is to conduct a phase Ia clinical study in GvHD patients to evaluate the safety and pharmacokinetic profile, and biomarkers of F-652 treatment by intravenous infusion (IV). IL-22 is a member of the IL-10 family of cytokines which control bacterial infection, homeostasis, and tissue repair. IL-22 may be used to treat patients with ALD because of its antioxidant, anti-apoptotic, anti-steatotic, anti-microbial, and proliferative effect that have been demonstrated in various experimental systems.
