Filter by:In vitro in the hepatitis C virus (HCV) replicon system, modulation of the biliary salts nuclear receptor FXR by either agonists or antagonists respectively increases or decreases the replication of HCV (J Hepatol, 2008, 48: 192-9). One antagonist of FXR is a vegetal sterol, guggulsterone, that is extracted from the Commiphora mukul tree and that has already been given safely to hyper cholesterolemic patients in a clinical trial (JAMA 2003, 290: 765-72). The aim of this trial is to test the effect of the FXR antagonist guggulsterone given orally, three times a day, on the viral load in 15 HCV genotype 1 chronically infected patients.
The primary purpose of this study is to determine whether the hepatitis C virus continues to remain unable to be detected in subjects who were previously treated with Asunaprevir (BMS-650032) and/or Daclatasvir (BMS-790052) and achieved sustained virologic response.
The aim of this study is to do an evaluation of the clinical profile of depression in HCV patients (newly diagnosed and treatment naïve), and in these same individuals, 24 weeks after the beginning of IFN+Ribavirin therapeutics (n=100). To characterize depression associated to HCV with and without interferon (IFN), the investigators will use clinical, behavioral, biochemical and genetic markers, and to distinguish their different symptomatologic dimensions. The control group will be composed by 100 individuals with Major Depression diagnosis, and not from the general population, because the investigators are not trying to study the incidence of depression in general population, but to characterize the clinical profile of patients with HCV (IFN+Ribavirin) compared to major depression. Thus, the investigators will total 300 evaluations in 200 individuals, 100 from each group, and considering that the clinical group will be evaluated before the therapeutics and re-evaluated 24 weeks after its beginning. Hypotheses 1. Depression in individuals affected by HCV is associated to genetic vulnerability. 2. Genetic vulnerability increases the risk of depression when IFN therapeutics is used. 3. Depression associated to infection by HCV presents a symptomatological profile that is different from general depression, which is maintained with IFN therapeutics. 4. A higher state of depression in the beginning of a treatment, if not treated, is a risk factor to abandoning therapeutics. 5. When comparing genders, women present a more severe symptomatological profile than men.
The purpose of this study is to compare the effectiveness of BMS-790052 (Daclatasvir) and Telaprevir when given in combination with Peginterferon alfa-2a and Ribavirin in genotype 1b patients
1. Adefovir add-on therapy is superior to switching to adefovir monotherapy or entecavir 1mg monotherapy for chronic hepatitis B (CHB) patients with lamivudine resistance (LAM-R) 2. Long-term adefovir add-on therapy was effective for viral suppression. However, the economic burden for such dual antiviral therapy is heavy because of infinite treatment. 3. Tenofovir disoproxil fumarate (TDF) is a potent antiviral agent. TDF demonstrated potent antiviral efficacy in a subset of lamivudine experienced HBeAg-positive patients. TDF is also superior to ADV in HBeAg-negative and HBeAg-positive treatment-naive patients. 4. Theoretically, TDF can replace LAM/ADV when viral suppression has been achieved by LAM/ADV combination treatment in LAM-R CHB patients.
Immunoprophylaxis failure of hepatitis B virus (HBV) leading to vertical transmission remains a concern and has been reported in approximately 8-15% of infants born to hepatitis B e antigen (HBeAg) positive mothers with high levels of HBV DNA. Maternal HBV DNA > 6log10 copies/mL (or >200,000 IU/mL) is the major risk for the mother-to-child transmission. Prior observational studies have shown that antiviral therapy including lamivudine or telbivudine use during late pregnancy can safely reduce the rate of vertical transmission in this special population compared to untreated patients. Tenofovir Disoproxil (TDF), a pregnancy category B medication, reduces HBV DNA and normalizes serum alanine aminotransferase (ALT) in chronic hepatitis B patients (CHB) with few adverse effects. Two aspects on tenofovir use in pregnancy will be evaluated prospectively in this study: 1. The data on its tolerability and safety in HBeAg+ pregnant women with HBV DNA > 6log10 copies/mL (or > 200,000 IU/mL) during late pregnancy and infants. 2. Its efficacy in the reduction of HBV vertical transmission rate.
In order to study the immunotherapeutic effects of electroporation (EP)-mediated dual-plasmids Hepatitis B Virus DNA vaccine, the investigators plan to conduct a double-blind, randomized, placebo-controlled trial, approved by Chinese State Food and Drug Administration with written informed consent from each chronic hepatitis B (CHB) patients with baseline ALT more than 2 times the ULN, for whom antiviral treatment is indicated and who were under the simultaneous lamivudine (LAM) chemotherapy.
The purpose of this study is to demonstrate the efficacy of TMC435 in combination with peginterferon (PegIFN) + ribavirin (RBV) by means of establishing its non- inferiority compared to an approved regimen of telaprevir + PegIFN + RBV in patients who have previously failed PegIFN.
This open-label, parallel cohort study will evaluate the safety, pharmacokinetics and antiviral activity of ritonavir-boosted danoprevir in combination with Pegasys (peginterferon alfa-2a) and ribavirin in treatment-naïve patients, and with RO5024048 added to the combination treatment in prior null responder patients with chronic hepatitis C genotype 1 or 4 and compensated cirrhosis. All patients will receive danoprevir 100 mg orally twice daily (bid) , ritonavir 100 mg orally bid, Pegasys 180 mcg subcutaneously weekly and ribavirin 1000-1200 mg/kg/day orally. Prior non-responders will receive RO5024048 1000 mg orally bid additionally. Anticipated time on study treatment is 24 weeks.
Hepatitis C virus (HCV) infection is a leading cause of death and illness in people with HIV-1. At the time the study was designed, the standard treatment for people with HIV-1 and HCV coinfection included two drugs: pegylated-interferon alfa 2b (PEG-IFN) and ribavirin (RBV). The purpose of this study was to evaluate the effectiveness of giving boceprevir (BOC) together with standard treatment in treating HCV infection in people with HIV-1 and HCV coinfection.
