Filter by:HIV infection exerts a negative impact on the course of HCV infection. Co-infected individuals progress more rapidly to liver fibrosis, cirrhosis and ESLD compared to those infected with HCV alone. Some of the this accelerated fibrosis may be related to longterm chronic toxicity from protease inhibitor based ART. Hypothesis: Switching from ritonavir boosted-PI based ART regimen to a Raltegravir-based regimen will reduce the rate of hepatic fibrosis progression in HIV-HCV co-infected patients as measured by transient elastography (Fibroscan®) and the AST-to-platelet ratio index (APRI).
This study will evaluate the effect of PF-04136309 in patients with chronic hepatitic C virus infection and abnormal liver enzymes.
This is a randomized, open-label, parallel group, multicenter pilot study evaluating the efficacy and safety of alternative dosing of ribavirin vs. standard of care dosing in combination with peginterferon alpha-2a in interferon naïve patients with chronic hepatitis c genotype 1 infection.
Vitamin D deficiency is commonly found in patients with chronic hepatitis C. The investigators hypothesize that the correction of hypovitaminosis D before the initiation of anti-HCV combination therapy and the maintenance of an optimal vitamin D status during antiviral therapy could improve the antiviral efficacy
Current European AIDS Clinical Society (EACS) guidelines for the treatment of HIV infection recommend a combination antiretroviral regimen composed of two nucleoside reverse transcriptase inhibitors plus a ritonavir boosted protease inhibitor or a non-nucleoside reverse transcriptase inhibitor. The non-nucleoside reverse transcriptase inhibitors licensed for naïve patients - nevirapine and efavirenz - have both been asociated with increased rates of hepatotoxicity (nevirapine) and CNS toxicity (efavirenz) in HIV/HCV co-infected patients. Although PI-based therapy has dramatically reduced morbidity and mortality, it has been limited by complex dosing regimens and toxicities, leading to adherence challenges. Varying degree of liver insufficiency may necessitate pharmacokinetic monitoring of the protease inhibitor and may necessitate dose adjustments. In HIV/HCV co-infected patients HAART based on another class of antiretrovirals than NNRTI or PI may thus offer advantages with regard to adverse events and thus long-term efficacy. The overall intention of this trial is to examine in a non-inferiority design the safety and efficacy of a raltegravir based HAART with a standard-of-care HAART in HIV-/HCV co-infected patients. The standard of care used in this study will be atazanavir/ritonavir. All patients will in addition receive a fixed combination of tenofovir and emtricitabine. The primary end-point is the rate of hepatotoxic events, defined by ALT elevations.
This phase 2b study will evaluate the efficacy and safety of 16 and 24 weeks of response-guided duration of therapy with GS-9190 and GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®). Additionally, the efficacy and safety of 24 weeks of GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) will be evaluated.
The purpose of this study is to assess the pharmacokinetics, safety and tolerability of single and multiple oral doses of TMC435 in Chinese healthy volunteers. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.
This randomized, open-label, active-controlled, parallel-group study will evaluate the sustained virological response of danoprevir boosted with low dose ritonavir in combination with Pegasys (peginterferon alfa-2a) and Copegus versus Pegasys and Copegus alone in treatment-naive patients with chronic Hepatitis C.
Purpose: The purpose of this exploratory study is to evaluate phosphoprotein profiling to determine differences in the intracellular actions of interferon or interferon stimulated genes among people with different treatment outcomes to interferon based therapy for hepatitis C (HCV). Participants: Patients with genotype 1 HCV who have had interferon based therapy at the University of North Carolina (UNC). Procedures: Thirty patients with varied responses to treatment will be given a single subcutaneous injection of interferon alpha 2b. Prior to the injection and at 30 minutes, 1,2,4,6,12 and 20 hours after injection, blood will be drawn for analysis of phosphoprotein profiling and changes in serum cytokines.
