Active clinical trials for "Hepatitis"

Genotype 1 hepatitis C virus (HCV) patients who did not respond (did not lose virus during treatment) or relapsed (virus went away on treatment but came back after treatment was stopped) after treatment with at least twelve weeks of a pegylated (long-acting) interferon and ribavirin will be considered for this study. There are two purposes to this study: first, to determine how rosiglitazone, a medicine used to treat diabetes, affects the HCV viral load; and second, to determine if treatment of insulin resistance with rosiglitazone prior to therapy for HCV will improve sustained virologic response (loss of virus that continues beyond six months after completion of HCV therapy) to HCV therapy.

The purpose of this study is to assess the efficacy and safety after administration of MP-424 to patients with chronic hepatitis C.

The primary objective of this study is to evaluate the effectiveness of TCM-700C as an add-on treatment to the combination drug therapy (Peginterferon α-2b plus Ribavirin) for patients with genotype 1 chronic hepatitis C infections. This will be demonstrated by a higher sustained virologic response rate, defined as the absence of detectable HCV RNA 24 weeks after the termination of combinational drug treatment, compared with the placebo add-on.

A study concerning viral kinetic with 10 co-infected HIV-HCV patients on treatment with peginterferon alfa-2a + ribavirin o IFN + ribavirin was reported in Conference on Retroviruses and Opportunistic Infections 2002 by Dr. Torriani shown half-life of HCV virions and the viral clearance was larger than mono-infected patients. The doubt is if this difference in viral kinetic of HIV-HCV co-infected patients versus mono-infected is related with the loss of profited on treatment. In the APRICOT trial patients genotype 2/3 were treated for 48 weeks and the relapse rates was only 2%. The present study want to evaluate is the treatment extent for 24 weeks more in patients genotype 1 and/or 4 will be improve the percentage of patients with viral clearance at the end of the follow-up period, to prevent relapsed in patients with response at the end of treatment. Patients will be randomized to received 180 µg/week of peginterferon alfa-2a + 1000-1200 mg/day of ribavirin during 24 weeks more or control.

Insulin resistance is known to adversely effect viral response to treatment in hepatitis C patients We are aiming to study the effect of an insulin sensitizer, metformin, in viral response of hepatitis C to treatment with pegylated interferon and ribavirin in a double blind randomized controlled trial

The purpose of this study is to assess the ability of eltrombopag to maintain a platelet count sufficient to facilitate initiation of antiviral therapy, to minimise antiviral therapy dose reductions and to avoid permanent discontinuation of antiviral therapy. The clinical benefit of eltrombopag will be measured by the proportion of subjects who are able to achieve a Sustained Virological Response (SVR).

Hepatitis C is one of the most common causes of long-term liver disease in the United States. Ribavirin and peginterferon alfa-2a are two medications that are used to treat hepatitis C infection. The purpose of this study is to evaluate the safety of these two medications in adults with hepatitis C and thalassemia, a type of blood disorder.

This 3 arm study will assess the efficacy and safety of PEGASYS + entecavir combination therapy in treatment-naive patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms s.c./week for 48 weeks, 2)PEGASYS 180 micrograms s.c./week for 48 weeks + entecavir 0.5mg p.o. once daily from week 13 to week 36 or 3) entecavir 0.5mg p.o. once daily for 24 weeks + PEGASYS 180 micrograms s.c./week from week 21 to 68. Treatment will be followed by 24 weeks treatment-free follow up. The anticipated time on study treatment is 3-12 months for groups 1 and 2, and 1-2 years for group 3, and the target sample size is 100-500 individuals.

When administered simultaneously, interferon-alpha 2b + interferon-gamma result in dramatic antiviral synergy.Ribavirin has shown to enhance interferon-gamma levels in patients with chronic hepatitis C treated with interferon-alpha. Enhancement of immune responses, especially those related to type-1 T helper cell activity, may contribute to better efficacy in combining ribavirin with IFN-alpha for treatment of chronic hepatitis C. The aim of the present study is to evaluate the efficacy and safety of a triple regimen, a combination treatment with Interferon gamma, Interferon alfa-2b plus Ribavirin in patients who have not previously responded to interferon alpha in combination of ribavirin.

The purpose of this study is to investigate how efficient TMC435350 will work against the Hepatitis C virus genotype 1 (genotypes refer to the genetic constitution of the virus) and what the concentrations of TMC435350 in the blood are with or without pegylated interferon alpha-2a (PegIFNa-2a) or PegIFNa-2a plus ribavirin.
