Active clinical trials for "Hepatitis C, Chronic"

A Study to assess the general safety and tolerability of the administration of a 3-dose prime/boost regimen of the MRKAd5 HIV-1 gag vaccine (V520) in subjects with chronic hepatitis C virus infection.

The purpose of this study was to assess the safety, tolerability, pharmacokinetics and antiviral activity of ABT-333 (also known as dasabuvir) in treatment-naïve, hepatitis C virus (HCV)-infected participants.

A short 14 day phase 1 study examining 6 monotherapy doses of oral tamoxifen for safety in chronic HCV patients who have failed standard treatment of peginterferon and ribavirin.

The purposes of the PLUS study were to confirm the safety and tolerability of two doses of LocteronTM (320 ug and 640 ug) dosed over four weeks in patients who had failed prior anti-HCV therapies (Panels A and B), and then to continue to study the safety, tolerability, and preliminary efficacy of the same two doses of LocteronTM (320 ug and 640 ug) in treatment-naïve genotype 1 HCV patients when Locteron dosed over 12 weeks (Panel C). All subjects were also to receive oral daily weight-based ribavirin.

The objectives are to determine the immunological profile (CD4+, CD8+ cells, DTH) induced by immunization with HCV antigen peptide vaccine with polyarginine. to document virological (HCV-RNA) and biochemical (ALT) responses following immunization with HCV antigen peptide vaccine with polyarginine. to assess the safety of immunization with HCV antigen peptide vaccine with polyarginine.

To determine the efficacy and safety of Peginterferón alfa-2a (40 KD) plus Ribavirin in patients who have relapsed or not responded to a previous suboptimal therapy based in Interferon.

The purpose of this study is to explore the efficacy, safety, tolerability, pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time), and pharmacokinetic-pharmacodynamic relationships of telaprevir administered in two different doses in combination with two standard therapies commercially available for chronic (lasting a long time) genotype 1 Hepatitis (inflammation of the liver) C virus (HCV) infection.

Silymarin (Legalon), also known as milk thistle, is an alternative medicine commonly found in health food and vitamin stores. People with liver disease sometimes use silymarin because it is thought to have liver protecting effects; however, this benefit has not been proven. The purpose of this research study is to determine the effectiveness of silymarin and assess the safety of different silymarin doses in patients with varying severity of liver disease compared to a placebo (lactose pill). Eligible subjects will be randomized to treatment with placebo or one of two dosages of Legalon® 420 mg or 700 mg administered orally thrice daily. Investigators and subjects will be masked to treatment assignment. The study design includes a screening period during which patients will undergo full medical evaluation to verify protocol eligibility and a treatment period of 24 weeks during which time clinic visits and laboratory studies will be performed every 2-4 weeks to monitor for safety and efficacy of therapy. Subjects will continue to be followed for an additional 12 weeks after the completion of study medication to monitor for adverse events and investigate post-treatment outcomes. Participation in this research study requires the subject to travel to the clinic for at least 10 visits so recruitment will be limited to a geographically restricted area around participating clinical centers.

The objective is to evaluate the efficacy and safety of combination therapy with peginterferon alfa-2b 1.0 µg/kg/week subcutaneous (SC) + ribavirin administered for 48 weeks in participants with chronic hepatitis C and type C compensated liver cirrhosis. Participants who are hepatitis C virus ribonucleic acid (HCV-RNA) positive after 24 weeks of treatment will be discontinued from therapy.

Study objective: Feasibility and efficacy of a standardised psychosocial intervention (psychoeducation) in substituted opioid dependent patients
