NCT ID: NCT00194480 Completed - Clinical trials for Substance-Related Disorders

Treatment of Acute Hepatitis C Virus Infection With Pegylated Interferon in Injection Drug Users

Start date: April 2003
Phase: Phase 4
Study type: Interventional

Injection drug use accounts for transmission of a high proportion of Hepatitis C Virus (HCV) infections. The purpose of this trial is to investigate the effectiveness of pegylated interferon in treating injection drug users (IDUs) with acute HCV.

NCT ID: NCT00192647 Completed - Clinical trials for Hepatitis C, Chronic

A Study of Induction Dosing With Peginterferon Alfa-2a (40KD) and Ribavirin in Participants With Chronic Hepatitis C (CHC) Genotype 1

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

This study will evaluate the addition of a higher-dose induction treatment period with peginterferon alfa-2a (Pegasys) and ribavirin prior to standard-dose treatment with Pegasys and ribavirin, compared to standard-dose treatment without induction dosing, in treatment-naive participants with CHC, genotype 1. The anticipated time on study treatment is 48 weeks, and the target sample size is 500 or more individuals.

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: NCT00188240 Recruiting - Hepatitis C Clinical Trials

Insulin Resistance Associated With Chronic Hepatitis C (CHC) and the Effect of Antiviral Therapy

Start date: August 2003
Phase: N/A
Study type: Interventional

The literature suggests that there may be an association between hepatitis C and type 2 diabetes mellitus independent of the presence of cirrhosis, the likely mechanism for which is insulin resistance. The prevalence of insulin resistance in patients with hepatitis C is unknown. Furthermore, there are no studies that indicate an increased prevalence of insulin resistance in patients with hepatitis C compared to other etiologies of liver disease. The role that hepatitis C may have in the development of insulin resistance is unclear. The effect of antiviral therapy for hepatitis C virus on insulin resistance has not been addressed. The long-term consequence of insulin resistance is type 2 diabetes mellitus. There is significant morbidity and mortality from type 2 diabetes mellitus in the general population, and similar complications would be expected in patients with hepatitis C and insulin resistance particularly if they develop type 2 diabetes mellitus. Our hypothesis: The prevalence of insulin resistance is increased in patients with chronic hepatitis C compared to chronic hepatitis B. Secondarily, insulin resistance when present in patients with chronic hepatitis C improves with successful antiviral therapy. This study has two phases. The first phase of our study will be to estimate the prevalence of insulin resistance in individuals with chronic hepatitis C without cirrhosis compared to patients with chronic hepatitis B without cirrhosis. The second phase of the study will be restricted to those patients with hepatitis C found to be insulin resistant from phase 1, in the absence of known risk factors for insulin resistance (cirrhosis, diabetes). The effect on insulin resistance of anti-viral therapy to eradicate hepatitis C will be assessed.

NCT ID: NCT00188201 Recruiting - Hepatitis C Clinical Trials

Neurocognitive Functioning in Patients With Hepatitis C Pre- and Post-Treatment With Antiviral Medication

Start date: January 2002
Phase: N/A
Study type: Observational

The estimated global prevalence of hepatitis C (HCV) infection is approximately 3% (170 million individuals). In Canada there are an estimated 240,000 people infected with HCV. The current study addresses the hypothesis that neurocognitive and neurochemical abnormalities may occur in individuals with HCV-infection who do not have liver cirrhosis or vasculitic neuropathy, and this may result from a direct effect of HCV on the Central Nervous System (CNS). The purpose of this study is to assess whether infection with the Hepatitis-C virus is associated with changes in thinking skills and brain chemistry, in patients who do not have liver cirrhosis. In addition, we are examining whether such changes in thinking skills and brain chemistry are reversed by antiviral treatment. We are also studying whether factors such as fatigue and depression have an effect on thinking skills in people with Hepatitis-C. In order to take into account the impact of having viral hepatitis, we will be comparing the results of the Hepatitis-C group to the results of a group of patients with Hepatitis-B, and to a group of individuals who do not have Hepatitis.

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: NCT00180674 Completed - Liver Fibrosis Clinical Trials

Anticoagulation in Liver Fibrosis in Patients With Hepatitis C Virus Infection

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

Patients who have been treated for hepatitis C virus (HCV) infection who have failed to respond to anti-viral treatment are often concerned about their ongoing liver disease and are therefore looking for alternative treatments which might prevent fibrosis progression. This view is endorsed by patient representative groups (including Charles Gore at the HepC Trust) who have welcomed this trial protocol. The study is a single centred, prospective, open labelled design. Practical as well as safety concerns dictated that the study could not be conducted in a blinded fashion, since patients taking anticoagulation require monitoring. The study consisted of two 8 week phases: Phase 1 and Phase 2. Phase 1 (observation phase, 0 to 8 weeks) and Phase 2 (treatment phase with warfarin anticoagulation, 8 to 16 weeks). Study completed at end of Phase 2.

NCT ID: NCT00179413 Active, not recruiting - Cirrhosis Clinical Trials

Study of Long-Term Peg Intron Vs. Colchicine in Non-Responders.

Start date: January 2001
Phase: Phase 4
Study type: Interventional

In this study Peg-Intron will be tested to see if it will give better results than Colchicine. At this time, there is currently no recommended maintenance treatment for patients who have failed to respond to Interferon/Rebetron/Peg Intron and have advanced fibrosis. The purpose of this study is to compare two treatments to slow down the progression of liver disease and to prevent liver failure and liver cancer. The treatment will not cure Hepatitis C, but is being evaluated to see if it can slow down disease progression.

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.
