Filter by:This trial is to assess the efficacy and safety of Polyethylene Glycol thymosin alpha1 (PEG-Tα1), a new long immunomodulator (Category 1.1 of Chemical Drugs) being developed from Hansoh Pharmaceutical of China, in combination with adefovir in HBeAg-positive patients with chronic hepatitis B.
The aim of interferon therapy in HBeAg negative chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after treatment withdraw. In this trail, entecavir will add on patients with HBV DNA load ≥1000copies/ml after 3 months of peginterferon alpha 2a treatment, and the efficacies of the combine treatment will be evaluated by the rate of sustained viral response after 48 weeks of treatment and 24 week follow up.
Background: - Chronic hepatitis B is caused by a virus that infects the liver. Cure is not possible but the virus can be controlled with the use of antiviral medicines,. Researchers think that adding a second antiviral medicine might help. Objective: - To understand how peginterferon might help treat people with chronic hepatitis B. Also, to see if peginterferon is safe to use with other antiviral medications. Eligibility: - Adults age 18 and older who have chronic hepatitis B and had therapy with 1 or more oral medicines for hepatitis B for at least 4 years. Design: - Participants will be screened with physical exam and medical history. They will complete health questionnaires about their levels of fatigue and pain. They will have blood and urine tests. They may have an eye exam. - Participants also will have a Fibroscan. A test to measure how stiff your liver is. - Eligible participants will have a liver biopsy. Blood will be drawn. - Participants will be admitted to the NIH Clinical Center. They will be injected with the study drug. Then they will have a second liver biopsy. They will be discharged 24 hours later. - Participants will give themselves study drug injections under the skin weekly for 24 weeks. - Participants will have 5 clinic visits during the 24-week treatment period. Then they will have follow-up visits every 12 weeks for 48 weeks. - During visits, participants may have a physical exam and medical history. They may have blood and urine tests. They may have a Fibroscan and complete questionnaires. At the final visit, they will also have a Fibroscan.
Antiviral therapy is the most important method to slow and stop the progress of the disease in patients with chronic hepatitis B (CHB). Nucleoside (acid) analogues (NA) can Effectively suppress HBV replication, but it should be continue used and relapse would happen in most patients after withdrawal of therapy. However, long-term use of NA could induce viral resistance mutation lead to loss of efficacy. Interferon treatment can enhance specific and non-specific immune function in chronic hepatitis B patients, make patients get immune control to HBV infection and obtain sustained response after treatment. Thus the CHB patients on the treatment of NA should be stop NA treatment after interferon treatment. In this study, the effects of interferon treatment in CHB patients who were on the NA treatment and obtained HBsAg level≤250 IU/ml.
This study is a multi-center, randomized, prospective, open-label Phase IV Clinical trial to evaluate efficacy and safety of interferon alfa-2b therapy combinated with interleukin 2 and hepatitis B therapeutic vaccine versus interferon alfa-2b alone in chronic hepatitis B patients with entecavir achieving HBeAg seroclearance. Patients were randomized to one of 3 groups to receive different antiviral treatment.
The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without sofosbuvir (SOF) and ribavirin (RBV) in DAA treatment-experienced adults with Genotype 1 Chronic Hepatitis C Virus infection. This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.
Objectives: Primary Objective: To identify and preselect patients with chronic HBV mono infection, who are undetectable for anti-Ad5 nAb, currently being treated with nucleo(t)sides, for participation in the TG1050.02 Phase1/1b First in Man (FIM) study. Secondary Objectives: To assess the prevalence of undetectable anti-Ad5 nAb in chronic HBV mono-infected patients. Methodology: Patients with chronic HBV mono-infection, who are currently being treated with nucleo(t)sides for their HBV infection, will be enrolled in this study to measure Ad5 nAb levels. A single peripheral blood collection (4 mL) will be obtained and Ad5 nAb titers will be measured by a central laboratory using a newly validated assay.
Patients with chronic HBV infection will receive ARC-520 in combination with entecavir or tenofovir and be evaluated for safety and efficacy.
The purpose of this study is to evaluate the efficacy of 6 or 8 weeks of treatment regimen containing simeprevir (SMV), daclatasvir (DCV) and sofosbuvir (SOF) in treatment-naive (not having received treatment with any approved or investigational drug) participants with chronic hepatitis (inflammation of the liver) C virus (HCV) genotype 1 infection with early stages of liver fibrosis or with cirrhosis.
Chronic hepatitis B (CHB) is a serious liver disease worldwide, and the leading cause of cirrhosis and hepatocellular carcinoma (HCC). HBsAg loss/seroconversion is considered to be the ideal endpoint of antiviral therapy in both HBeAg-positive and -negative patients, and the ultimate treatment goal in CHB, However HBsAg loss occurred rarely by interferon treatment. Although It was reported that in nature history HBsAg level≤100 IU/ml can bring good long term outcomes in patients with chronic hepatitis B. it was not clear whether patients who achieved HBsAg level≤100 IU/ml by interferon treatment could maintain sustained viral response and the state of HBsAg level≤100 IU/ml.
