The Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) trial is a multicenter clinical trial conducted to assess the effects of long-term antiviral drug therapy on the progression of liver disease in patients who have advanced chronic hepatitis C and have not responded to prior therapies. Chronic hepatitis C is a long-lasting viral infection affecting the liver that may lead to permanent liver damage and cirrhosis (replacement of healthy liver cells by scar tissue). If left untreated, a proportion of patients with chronic hepatitis C will be at risk for complications of liver disease. The drug therapy in the HALT-C trial was designed to clear the hepatitis C virus from the patient s system in order to prevent or mitigate these potential complications. The purpose of this research is to determine if patients with chronic hepatitis C who experienced clearance of hepatitis C virus (known as a sustained virologic response, or SVR) during the HALT-C trial have developed any complications of their liver disease. This study will include 180 subjects who participated in the initial phase of the HALT-C trial and experienced an SVR. The participants will visit the National Institutes of Health for an in-person study visit. During the visit, patients will have blood drawn for lab tests to monitor the progress of their liver disease, and may be asked to undergo an ultrasound examination of the liver to detect any abnormalities that may be attributed to liver cancer. Patients will also answer questions about their medical history particularly any outcomes or events related to their hepatitis C that have occurred since the HALT-C trial and may be asked to sign a release of information to allow researchers to obtain medical records from other clinics or physicians where they have received treatment. ...
To determine safety, tolerability, and preliminary efficacy of escalating doses of SD-101 alone and SD-101 plus ribavirin in subjects with chronic hepatitis C and no prior therapy.
The purpose of this study is to evaluate the effect of cyclosporine, an anti-rejection drug, on the clearance of the hepatitis C virus in liver transplant subjects being treated with peg-interferon and ribavirin.
Hepatitis C Virus is constantly evolving genetically, particularly in response to the immune system. This is an observational study to examine if immunosuppressants particularly calcineurin inhibitors taken by transplant patients in order to avoid organ rejection causes predictable changes in the genetics of this virus that might be important in order to treat it effectively.
The purpose of this study is to assess anti-viral activity (inhibition of viral growth) of TMC435350 in genotype 2,3,4,5 and 6 hepatitis C virus infected participants who have never received treatment for their hepatitis C infection.
This is a proof-of-concept study which will provide data about the safety and antiviral activity of several doses of the investigational drug IDX184 given for 3 days in treatment-naive HCV genotype 1-infected subjects so that optimal doses can be chosen for testing in later studies.
The purpose of this study is to compare the safety, tolerability and effectiveness of 12 weeks of treatment with telbivudine 600 mg daily plus tenofovir DF 300 mg one daily (OD) taken together vs. tenofovir DF 300 mg once daily (QD) or vs telbivudine 600 mg monotherapy daily (QD). This is an open labeled, active controlled, viral kinetics study which means the subjects and study doctor will know what study drug subjects have been assigned. This study is open to male and female subjects, <40 years of age, who have been infected with HBV for at least 6 months and have not received oral treatment for HBV.
The aim of this Observer-blind study is to compare different Adjuvant Systems with the same, well-known antigen (HBsAg) already used in the GSK marketed vaccines against Hepatitis B (Engerix-BTM and FendrixTM), in order to better understand the immune response induced by each of the Adjuvant System. This Protocol Posting has been updated following Protocol amendment 6, October 2009. The section impacted is Eligibility Criteria
