Filter by:The study aims to study the outcome of pharmacokinetics-adjusted dose ribavirin (plus pegIFN) on the SVR in chronic HCV patients.
The purpose of this study is to evaluate the safety and efficacy of co-administration of ABT-450 (also known as paritaprevir) with ritonavir (ABT-450/r) and ABT-267 (also known as ombitasvir) in adults with chronic hepatitis C virus infection.
In the current practice patients with normal levels of ALT were not treated. However, a percentage of patients will present an advanced grade of fibrosis and cirrhosis. Another reason to treat is the similar response to the treatment than elevated ALT patients published recently in mono-infected patients. The investigators have not data concerning the evolution and response to the treatment in co-infected patients with normal ALT. In the story of treatment chronic hepatitis C of co-infected patients HCV/HIV, sometimes, it assumes a behavior similar between mono and co-infected patients and the results are different. In the case of normal ALT the investigators do not know if the natural history in co-infected patients is similar than the mono-infected patients, and also the response of the treatment. This study prospective and controls is the answer of this question. The main hypothesis is if the response of treatment in co-infected patients is not inferior than mono-infected patients. The objective is to evaluate the efficacy and safety of peginterferon alfa-2a and ribavirin in HIV positive patients with chronic hepatitis and persistently normal ALT. Every CASE (patient with normal ALT) will have a CONTROL (patient with elevated ALT), concerning genotype, gender and hospital.
This study will evaluate the safety, tolerability, and antiviral efficacy of GS-7977 with ribavirin (RBV) in participants with genotype 2 or 3 hepatitis C virus (HCV) infection.
Conduct a randomized controlled trial (RCT) to test the hypothesis that offering client-centered HIV counseling and testing (HCT) to blood donor candidates will reduce the risk of HIV contamination in the blood supply and also increase appropriate referrals to preventive and care services to persons in need in São Paulo, Brazil.
This multicenter, observational study will assess the efficacy and the safety of Pegasys (peginterferon alfa 2a) in dual- or triple therapy in patients with chronic hepatitis C. Patients will receive Pegasys and/or ribavirin and/or a protease inhibitor according to local guidelines. Data will be collected for 96 weeks.
This study will evaluate the technical feasibility of using fine needle aspiration (FNA) of liver tissue to obtain vaniprevir (MK-7009) liver pharmacokinetic (PK) data, working towards identifying a minimally invasive, reproducible platform to measure liver PK. The study will be done in 2 parts. In Part 1, participants will be randomized to one of five FNA/core needle biopsy (CNB) time-point collection sequences. In Part 2, participants will be randomized to one of two possible doses of vaniprevir and will be assigned to one of five FNA/CNB time-point collection sequences; participants in Part 2 will also receive background therapy with pegylated interferon alpha-2b (Peg-IFN alpha-2b) and ribavirin (RBV). The primary hypothesis is that there is a greater than 80% posterior probability that vaniprevir concentrations are successfully obtained at least 60% of the time from FNA liver samples collected at 2 of 3 specified timepoints.
This multicenter study will evaluate the correlation of interleukin 28B (IL28B) genotypes with disease characteristics and demographics in treatment-naïve and treatment-experienced chronic hepatitis C patients, including patients with HIV co-infection. There will be a single study visit for testing.
The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1b (HCV GT1b) infection without cirrhosis.
This study evaluated the safety, tolerability, antiviral activity, and pharmacokinetics of ABT-450 (also known as paritaprevir) with ritonavir (ABT-450/r) and ABT-267 (also known as ombitasvir) in adult Japanese patients with chronic hepatitis C virus genotype 1b (HCV GT1b) or genotype 2 (HCV GT2) infection who were previous treated with pegylated interferon/ribavirin (pegIFN/RBV).
