Filter by:The objective of this study is to provide open label emtricitabine/tenofovir disoproxil fumarate (DF) for an additional 5 years to subjects completing study GS-US-203-0107.
This study is a long-term post-treatment follow-up to study WV19432, which evaluated the efficacy and safety of PEGASYS in patients with HBeAg positive chronic hepatitis B (CHB).Patients who received treatment with PEGASYS, and completed follow-up, are eligible to enter this post-treatment follow-up study. The anticipated time on study was 5 years, and the target sample size is 100-500 individuals.
The purpose of this study is to determine if rosiglitazone, a medicine used to treat diabetes, improves response to anti-viral treatment.
This single arm study will evaluate the safety and tolerability of ribavirin in combination with PEGASYS in patients with chronic hepatitis C. Patients will receive ribavirin 800mg, or 1000-1200mg po daily, according to HCV genotype and body weight (< and >75kg)in combination with PEGASYS 180micrograms sc weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is >500 individuals.
This 3 arm study will assess the efficacy and safety of PEGASYS alone, or in combination with Adefovir or Entecavir in patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms sc weekly for 48 weeks + placebo from weeks -4 to 2;2)PEGASYS 180 micrograms sc weekly for 48 weeks + Adefovir from weeks -4 to 2; or 3)PEGASYS 180 micrograms sc weekly for 48 weeks + Entecavir from weeks -4 to 2. Treatment will be followed by 24 weeks of treatment-free follow-up.The anticipated time on study treatment is 1 year, and the target sample size is 100-500 individuals.
Background: - Liver cancer is the third most deadly and fifth most common cancer worldwide. Hepatocellular carcinoma (HCC) is the most frequent primary liver cancer, and it has grown more prevalent in the United States. - More information is needed about the causes and effects of liver cancer, and further research into individuals who are at high risk for developing liver cancer is needed for early diagnosis and prevention. Objectives: - To identify genetic factors that may help to explain the aggressiveness of liver cancer. - To determine if HCC biomarkers exist in blood, urine, and tissue samples. Eligibility: - Patients between the ages of 18 and 90 who have been diagnosed with HCC or have a high risk for developing HCC because of fatty liver disease (alcohol-related or non-alcohol-related) or chronic hepatitis B or C. - Participants will reside in Baltimore City and the surrounding areas. Design: - Participants will complete a questionnaire and provide blood and urine samples for testing: - The questionnaire will include questions about individual and family medical history, tobacco use, and exposure to known factors for liver cancer. - Blood and urine samples will be collected from all participants after the questionnaire. - Tumor tissue and healthy tissue will be collected from selected participants if they undergo surgery for their cancer or disease. - No specific treatment will be offered as part of this protocol, but participants have the option to be treated under different protocols.
The purpose of this study is to assess antiviral activity when administered alone for 3 days or in combination with peginterferon and ribavirin for 12 weeks. This study will also evaluate the safety and tolerability of treatment with VCH-222 when given alone or in combination with peginterferon and ribavirin. The study will also evaluate the pharmacokinetic profile of VCH-222 in HCV infected subjects.
The purpose of the study is to investigate if the duration of treatment of hepatitis C with pegylated interferon and ribavirin can be individualized on the basis of how fast the hepatitis C virus concentration in the blood decreases, and if this is more cost-efficient than standard treatment.
The purpose of this study is to investigate T-cell mediated immune responses to HIV-1 and HCV and determine how these responses are affected by HCV treatment and correlates to response. Furthermore, to study Interferon-inducible protein-10 (IP-10) dynamics during HCV treatment, and correlate this to treatment outcome.
This is a Phase I, open-label, single-dose study to evaluate the pharmacokinetics and safety of LDT600 in pediatric and adolescent patients with chronic hepatitis B infection.
