Active clinical trials for "Hepatitis"

HBsAg Loss/Seroconversion is uncommon in Low replicative chronic HBV infection patients. The purpose of this study is to investigate the ability of peginterferon alpha to achieve HBsAg loss/seroconversion therapy in Low replicative chronic HBV infection patients with Low Level HBsAg.

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.

The main purpose of the study is to compare the efficacy of two strategies aimed to rescue patients lost to follow-up with active infection or with positive HCV antibodies without RNA request to complete evaluation and prescription of treatment in cases of chronic infection. After patient identification from data files of laboratory and microbiology charts, patients will be randomized to: a) phone call, and b) invitation letter, both of two strategies including a scheduled appointment with the hepatologist.

The study hypothesis is to determine the feasibility of switching HIV-HCV co-infected patients receiving methadone or buprenorphine/naloxone as opioid substitution therapy with suppressed HIV RNA viral load on current antiretroviral therapy to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF, Genvoya™) followed by 12 weeks of HCV antiviral therapy with sofosbuvir/velpatasvir (SOF/VEL, Epclusa™), followed then by switch to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF, Biktarvy™) for an additional 48 weeks.

Both tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) are potent antiviral agents for hepatitis B virus (HBV) and recommended by the American Association for the Study of Liver Disease (AASLD) as well as the European Association for the Study of Liver (EASL) guidelines for the treatment of nucleos(t)ide therapy induced HBV resistance. However, it is not clear if chronic hepatitis B (CHB) patients with nucleos(t)ide treatment experience without genotypic mutations would be benefit from TAF therapy. Previous studies have observed that suboptimal response (SOR) following antiviral therapy with nucleos(t)ide treatment is associated with an increased risk of subsequent treatment failure and viral resistance. It remains unclear whether switching to TAF is a reasonable approach in patients with SOR to second-line antivirals Lamivudine (LAM)/ Telbivudine (LdT)/ Adefovir Dipivoxil (ADV) and its combinations with other second-line antivirals for 24 weeks, or SOR to the first-line antiviral Entecavir (ETV) or any antiviral combinations containing ETV for 48 weeks. This study is aimed to determine how the aforementioned patients with SOR to nucleos(t)ide treatment respond to TAF monotherapy. The investigator's study will provide evidence base for therapy selection in SOR patients, especially in China where the majority of patients with CHB are treated with nucleos(t)ide therapy.

A total of 80 adult chronic hepatitis B patients with advanced liver fibrosis (including fibrosis stage 3 and cirrhosis), who are currently on nucleot(s)ide analogs (except tenofovir alafenamide) therapy with detectable HBV DNA after 52 weeks of therapy will switch prior NUCs to TAF 25 mg/day for 96 weeks

Phase II: Exploring the efficacy and safety of different doses of SH229 tablets combined with fixed-dose Daclatasvi dihydrochloride (DCV) tablets in the treatment of adult patients with chronic hepatitis C for 12 weeks, providing a basis for the design and implementation of phase III clinical trials. Phase III: Confirmation of the efficacy and safety of SH229 tablets combined with Daclatasvi dihydrochloride (DCV) tablets in the treatment of adult patients with chronic hepatitis C for 12 weeks, providing a sufficient basis for drug registration and clinical use.

This study is to investigate the clinical efficacy and safety of RL-1 Novel Human-derived Bio-artificial Liver treatment in patients with Hepatitis b virus related acute-on-chronic liver failure.
