Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to evaluate the percentage of participants with sustained virologic response 12 weeks after the actual end of study treatment (SVR12)

Aim of the present study is to evaluate in a cohort of patients with genotype 2/3 chronic hepatitis C, relapsers to a previous PEG-IFN + ribavirin therapy (alpha-2a or alpha-2b) the efficacy of PEG-IFNα-2a + ribavirin administered for 24 or 48 weeks. It will be evaluated whether 48 weeks of therapy may achieve better results compared to the standard duration (24 weeks).

This open-label, non-comparative study will assess the safety and tolerability of individualized combination therapy with Copegus (ribavirin) and Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis C. Patients with hepatitis C virus (HCV) genotype 1 (Group A) will receive Copegus 1'000 mg or 1'200 mg daily orally for 24-72 weeks. For patients with genotype 2 or 3 HCV (Group B) the Copegus dose will be 800 mg daily for 16-48 weeks. Patients who had previously received standard or pegylated interferons but were non-responders or with relapse (Group C) will receive Copegus 1'000 mg or 1'200 mg daily for up to 72 weeks. Concomitant therapy with Pegasys 180 mcg subcutaneously weekly will be given to all patients. Anticipated time on study treatment is up to 72 weeks with a 24-week follow-up.

This is a three-part (Part A, Part B, and Part C), open-label, multicenter study of boceprevir in pediatric participants with chronic hepatitis C (CHC) genotype 1 (GT1). In Part A and Part B, efficacy and safety will be evaluated in participants with CHC GT1 who are non-cirrhotic, treatment naïves (Part A) or who are non-cirrhotic, treatment failures to (peg)interferon/ribavirin or who are cirrhotics (whether treatment naïve or treatment failure) (Part B). Part C is long-term follow up and no study treatment will be administered during this period, but participants who do not achieve viral clearance will be allowed to receive other treatments for CHC.

Our previous collaborative studies has developed a molecular diagnosis tool, which is characterized with a prediction model consisting single nucleotide polymorphisms (SNPs), for assessing the efficacy of interferon combined therapy for chronic hepatitis C (CHC) patients prior to treatment. Aims of this project: To analyze and validate the gene expression profiling dependent of treatment response to peg-interferon-α plus ribavirin combination therapy in CHC genotype-1 patients. To select the candidate genes and establish a monitoring model assessing the efficacy of interferon treatment.

Confirm the safety of maraviroc when used as a component of combination antiretroviral therapy in HIV and Hepatitis co-infected patients.

The HALT-C Trial is a National Institute of Diabetes and Digestive and Kidney Diseases sponsored, randomized clinical trial of long-term use of Peginterferon alfa-2a (pegylated interferon) in patients who failed to respond to prior interferon treatment. All patients who enter the trial will be treated for 6 months with Peginterferon alfa-2a and Ribavirin. Patients who respond to this 6 month treatment will continue to be treated for an additional 6 months. Patients who do not respond to this treatment will be eligible for the long-term maintenance phase of this study where patients will be randomly selected to be treated with Peginterferon alfa-2a or to discontinue treatment for 3.5 years. Patients in both arms of this study will be followed closely with quarterly study visits. The combination of peginterferon plus ribavirin has recently been approved by the FDA for treatment of chronic hepatitis C. Patients who remain HCV-RNA positive after being treated for at least 6 months with peginterferon and ribavirin outside of this study may be eligible to directly enter the randomized portion of the HALT-C Trial. The HALT-C study is designed to determine if continuing interferon long-term over several years will suppress Hepatitis C virus, prevent progression to cirrhosis, prevent liver cancer and reduce the need for liver transplantation.

The Birth-Cohort Evaluation to Advance Screening and Testing for Hepatitis C (BEST-C) compares the effectiveness of the birth cohort HCV screening strategy with the current risk-based screening approach to detect previous unidentified persons with viral hepatitis C who receive health care in primary systems. The study involved three clinical sites, The University of Alabama, Birmingham; The Henry Ford Health System; and the Mount Sinai Medical Center, each of which developed an independent intervention to experimentally compare the number of positive Hepatitis C Virus (HCV) diagnoses found using the birth-cohort screening approach with that found using traditional risk-based screening, or standard of care strategies. Birth cohort testing is defined as the systematic recommendation of HCV antibody testing to any persons born during the years of 1945 to 1965 who do not have clinically documented evidence of a prior antibody test without regards to the patient's stated risk of exposure to the virus.

The purpose of this study is to examine whether neurocognitive impairments experienced by patients with chronic hepatitis C virus (HCV) infection can be reversed by treating HCV, with a new combination of direct acting antiviral drugs (daclatasvir (DCV), asunaprevir (ASV) and beclabuvir (BCV)). The study will assess the effect of HCV on the central nervous system (CNS) by assessing neurocognitive function and brain injury prior to treatment, and comparing it to the end of treatment, and 4, 12 and 24 weeks after treatment.

The objectives of this study are: To evaluate the efficacy and safety of two different treatment regimens with BI 201335 (high dose given for 12 weeks or low dose given for 24 weeks both in combination with Pegylated interferon-a and Ribavirin (PegIFN/RBV) as compared to PegIFN/RBV alone in treatment-naïve (TN) chronic genotype 1 hepatitis C virus infected patients. Evaluate the efficacy and the safety of BI 201335 high dose given for 12 weeks in combination with PegIFN/RBV given for 24 to 48 weeks as compared to PegIFN/RBV alone in chronic GT-1 hepatitis C virus infected relapser patients who failed a prior PegIFN/RBV treatment.
