Filter by:Viral hepatitis C is treated with peg-interferon alpha 2a/2b and ribavirin. There is no treatment recommended for non responders patients. This study will evaluate the efficacy, after a second treatment with peg-interferon alpha 2a and ribavirin for 12 Weeks of the addition of interferon gamma in non responders patients
Viral hepatitis C prognosis is related to the presence of a fibrosis and to the risk of developing cirrhosis or hepatic cancer. The study will evaluate the efficacy of prazosin to make hepatic fibrosis regress, in patients with chronic hepatitis C and severe fibrosis.
* Adding Amantadine to standard anti-viral treatment can improve sustained response rates in patients with chronic hepatitis C
This study evaluated the efficacy and safety of the combination of peginterferon alfa-2a plus ribavirin in treatment-naïve patients with HCV genotype 1b infection, compared with peginterferon alfa-2a monotherapy. Additionally, the study evaluated the efficacy and safety of the combination of peginterferon alfa-2a plus ribavirin in patients with CHC who had failed to respond to previous conventional-interferon based therapy.
In order to prevent organ rejection, patients receiving liver transplants currently require life-long treatment with immune system-suppressing medications to prevent the rejection of the transplanted liver. However, these medications can cause long-term side effects, such as infection, kidney problems, diabetes, and cancer. In patients infected with hepatitis C virus (HCV), these medications may increase the risk of HCV infection in the transplanted liver. The purpose of this study is to determine whether a slow withdrawal of immune system-suppressing medications is safe in two groups of subjects: those who receive a liver transplant due to HCV, and those who receive a liver transplant due to non-immune, non-viral causes of liver failure. The study will also look at whether slow withdrawal will help reduce the long-term side effects of immune system-suppressing medications and decrease the chance for HCV infection of the new liver in transplant patients with HCV.
This was a randomized, multi-center, partially placebo-controlled Phase IV study to compare the efficacy and tolerability of a 48-week combined therapy with pegylated interferon alpha-2a, ribavirin and amantadine sulphate versus placebo in untreated patients with chronic hepatitis C virus-genotype-1-infection. The hypothesis was that there will be an increase in sustained response rate for triple therapy compared to current standard treatment.
The GI-5005 therapeutic vaccine or placebo will be injected under the skin of hepatitis C virus (HCV) subjects. Patients will be monitored for safety, immune responses and any therapeutic benefits related to the injections.
Triple antiviral therapy with peg-interferon-alfa/ribavirin+amantadine was suggested to increase sustained virological response (SVR) rates in HCV non-responders to a standard interferon/ribavirin combination. Patients with hepatitis C virus infection were eligible if they had failed to respond to a single previous 24 week cycle of interferon/ribavirin combination therapy. Non-response was defined as persistent HCV RNA in the serum during the last month of treatment. This study tested the efficacy and safety of pegylated interferon alfa-2b with ribavirin and amantadine or a placebo for 48 weeks.
The aim of this study is to prove the efficacy of peginterferon in HIV infected patients with liver disease caused by hepatitis C virus (HCV) when the treatment to eradicate the virus failed. This scientific proof needs a comparative study to be done including two groups of patients randomly allocated: one with the treatment (peginterferon) and the other without any treatment against HCV with a duration of 2 years. To conclude, two liver biopsies are needed; one before the study and a second 2 years after.
This study is being conducted to compare the safety, effectiveness and tolerance of valopicitabine (NM283) when used alone and when valopicitabine is used together with pegylated interferon in hepatitis C treatment failure patients. These results will be compared against the results of treatment with pegylated interferon plus ribavirin, the current standard therapy for treatment of hepatitis C viral infection.
