NCT ID: NCT00192569 Completed - Hepatitis C Clinical Trials

Australian Trial in Acute Hepatitis C

Start date: July 2004
Phase: Phase 4
Study type: Interventional

Australian Trial in Acute Hepatitis C (ATAHC) A prospective non-randomised dual arm longitudinal cohort of newly acquired hepatitis C infection into which participants will be enrolled and then followed at 3 monthly intervals over a 3 year period. All participants will be offered a 24 week course of pegylated interferon alfa 2a which will be commenced within 12 weeks of screening (patients coinfected with HIV will be offered 24 weeks with pegylated interferon alfa 2a plus ribavirin).

NCT ID: NCT00189163 Completed - Chronic Hepatitis C Clinical Trials

Pioglitazone in Hepatitis C

Start date: January 2005
Phase: Phase 4
Study type: Interventional

The presence of insulin resistance (IR) appears to be a key factor in the development of steatosis and disease progression in patience with Hepatitis C virus (HCV) genotype-1 infections similar to levels in Non-alcoholic fatty liver disease (NAFLD). The objective of this study is to determine whether Pioglatizone, when given along with Interferon and Ribavirin, reduces insulin resistance and lowers HCV viral levels and improved response in patients who have HCV genotype-1 infection when compared to a placebo.

NCT ID: NCT00187473 Completed - Chronic Hepatitis C Clinical Trials

Natural History of Hepatitis C in Patients With Normal Liver Tests

Start date: June 2000
Phase:
Study type: Observational

The Major goals of this project was to assess the natural history of disease in chronic hepatitis C patients with normal ALT and to determine the virologic and host factors associated with disease severity.

NCT ID: NCT00186836 Completed - Hepatitis B Clinical Trials

Efficacy Study of Combined Hepatitis A and Hepatitis B Vaccine to Protect Against Hepatitis B in Hemodialysis Patients

Start date: November 2004
Phase: Phase 4
Study type: Interventional

Does vaccinating hemodialysis patients with Twinrix® (combination vaccine against hepatitis A and hepatitis B) result in a difference in hepatitis B antibody response in comparison to the monovalent hepatitis B vaccine? Hepatitis B infection is an important cause of mortality and morbidity. Current standard vaccination practices have low efficacy levels in patients (eg. hemodialysis patients) who are most susceptible of infection. Efficacy of the two regiments will be studied.

NCT ID: NCT00175435 Completed - Hepatitis B Clinical Trials

Optimizing Hepatitis B Vaccine Response Through the Use of a Topical Immune Modulator

Start date: August 2005
Phase: Phase 1/Phase 2
Study type: Interventional

This study will look at what happens to the level of protection against hepatitis B (HB) disease if a 'helper' gel is applied to the skin over the injection site of a small dose of hepatitis B vaccine.

NCT ID: NCT00172809 Completed - Clinical trials for End Stage Renal Disease

Interferon Treatment for Patients With Chronic Hepatitis C and End Stage Renal Disease

Start date: July 2005
Phase: Phase 4
Study type: Interventional

The treatment response with conventional interferon alpha alone in patients with end stage renal disease and chronic hepatitis C is about 33-39%. However, the drop-out rate is 17-29.6%. Pegylated interferon alpha, a newly developed form of interferon with superior pharmacokinetic profiles, has not been used to treatment these patients. We expect the better treatment response treated with peginterferon alpha than conventional interferon. In addition, we also observe the safety of the two drugs during the study. The goal of the study is to compare the efficacy and safety of the two different treatment regimens in patients with chronic hepatitis C and end stage renal disease.

NCT ID: NCT00168194 Completed - HIV Infections Clinical Trials

Cellular Immune Responses to Hepatitis B Virus (HBV)- Longitudinal Follow up and Natural History

Start date: December 2004
Phase: N/A
Study type: Observational

It remains unclear why some individuals are able to clear HBV from their bodies while in others HBV is a persistent infection. We plan to investigate this process by collecting blood and analysing how the patient's white blood cells respond to different pieces of the HBV virus. We will use new tools that can precisely tell us which component of the immune response may be different in individuals who are chronically infected with HBV and also in individuals who are also infected with HIV. The primary aims are therefore: 1. To characterize HBV-specific T cell responses in HBV chronic carriers, and identify novel immunogenic regions in both HLA-A2+ and non-HLA-A2+ individuals. 2. To determine the effect of HIV infection on HBV-specific T-cell responses

NCT ID: NCT00166296 Completed - Clinical trials for Major Depressive Disorder

Efficacy and Safety of Escitalopram for Prevention of Depression Induced by Peg-Interferon in Hepatitis C Patients

Start date: March 2005
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine whether the use of an antidepressant (escitalopram) can prevent depressive episodes that appear during the treatment with peg-interferon and ribavirin in patients with chronic hepatitis C.

NCT ID: NCT00160251 Completed - Chronic Hepatitis C Clinical Trials

Boceprevir (SCH 503034) Plus Peg-Intron, With and Without Added Ribavirin, in Patients With Chronic Hepatitis C, Genotype 1, Who Did Not Respond to Previous Treatment With Peginterferon Alfa Plus Ribavirin (Study P03659AM2)(COMPLETED)

Start date: September 2005
Phase: Phase 2
Study type: Interventional

The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir.

NCT ID: NCT00158756 Completed - Hepatitis B Clinical Trials

Immune Response Post Pry Vaccination of 2 Formulations of DTPw-HBV Vaccine Given With Rotavirus Vaccine to Infants

Start date: September 12, 2005
Phase: Phase 3
Study type: Interventional

To compare the two formulations of GSK Biologicals' DTPw-HBV vaccine to concomitant administration of CSL's DTPw vaccine and GSK Biologicals' HBV with respect to the antibody response to the diphtheria antigen after a three-dose primary vaccination course.
