Filter by:This study will provide chronic hepatitis C patients with low platelets (less than 75x10^9/L) the opportunity to undergo treatment and possible cure of their virus. The main hepatitis C drugs will be administered as standard of care, with the addition of the study drug eltrombopag. The investigators hypothesize that providing eltrombopag to chronic hepatitis C patients with low platelets (less than 75x10^9/L) will permit the initiation and completion of antiviral triple therapy with boceprevir, ribavirin, and pegylated-interferon.
This prospective, national, multicenter, observational study will evaluate in routine clinical practice the efficacy and safety of re-treatment with Pegasys (peginterferon alfa-2a) plus ribavirin or regimens containing direct-acting antivirals in participants with chronic hepatitis C who failed previous treatment. Participants will be followed for the duration of their treatment (24, 48 or 72 weeks) and for 24 weeks of follow-up.
All subjects in this study have previously been in an Idenix HCV study and received study drug for 3 consecutive days. Subjects who had received placebo in a previous Idenix study will not be enrolled in this study. In this study, researchers will try to find answers to these questions: - How much (if any) hepatitis C virus is in your blood after stopping your Idenix study drug? - Is your hepatitis C virus possibly resistant to treatment with the Idenix study drug or similar drugs?
The purpose of this study is to determine the safety, tolerability, pharmacokinetics (what the body does to the medication) and antiviral activity of JNJ-47910382 when administered in different dosing regimens in Caucasian genotype-1 chronic HCV-infected patients.
The purpose of this study is to evaluate the effect of PEGASYS® (peginterferon alfa-2a 40KD) plus Robatrol® (ribavirin) combination therapy given for 36 weeks versus 48 weeks on the clearance of HCV viremia 24 weeks after treatment end
The purpose of this study is to assess the efficacy of a short course of therapy (24 weeks) versus standard 48 week treatment in previously untreated adult participants with chronic hepatitis C (CHC) genotype 4 infection who achieve rapid virologic response (RVR), defined as HCV ribonucleic acid (RNA) negativity after 4 weeks of treatment.
Patients are being asked to be part of this study because they are a liver transplant recipient and have the Hepatitis C Virus (HCV). Current routine treatment for HCV for liver transplant patients includes taking two medications called pegylated interferon alfa-2a (Pegasys®) and ribavirin. Patients Pegasys and ribavirin are FDA approved for the treatment of HCV. This study will evaluate the safety and efficacy of adding a third drug called telaprevir for the experimental treatment of HCV in liver transplant patients. The combination of Pegasys, ribavirin and telaprevir is currently FDA approved for the treatment of HCV, but is specifically not FDA approved for HCV patients who have had a liver transplant. This is because more information is needed about possible drug interactions between telaprevir and cyclosporine, or telaprevir and tacrolimus-based immunosuppressive drugs, which are typically part of routine care for transplant patients. Studies have shown that the addition of telaprevir greatly increases the efficacy of Pegasys and ribavirin for the treatment of HCV. However, these studies did not include adequate information on transplant patients due to the potential drug interactions. The investigators hope to gather more information about the safety and efficacy of telaprevir given in combination with Pegasys and ribavirin in the liver transplant patients who have HCV that is not well controlled with Pegasys and ribavirin alone.
The purpose of this study is to determine the safety, tolerability, pharmacokinetics (how a drug is absorbed and distributed in the body), and intrinsic antiviral activity of JNJ-47910382 after 5 consecutive days of administration in chronic, hepatitis C virus (HCV)-genotype-1-infected patients at different doses and dose regimens.

Hepatitis C infection is a major public health problem with nearly 175 million infected individuals worldwide. Although cure is possible, only 20-40% of patients spontaneously resolve infection and 40-80% of chronically infected patients (numbers vary depending on viral genotype) that receive pegylated-interferon-alfa2a/ribavirin therapy clear the virus and are sustained virologic responders (SVR). Still for many, the virus manages to circumvent natural immunity and current therapeutic strategies, resulting in significant morbidity and mortality. To better define the distinct clinical outcomes of HCV infection many investigators have performed candidate molecules screens or transcriptional profiling in order to identify correlates of viral clearance. One molecule that has gained significant attention is CXCL10 (also known as interferon-gamma induced protein-10 or IP-10) as an important negative prognostic biomarker. Given that CXCL10 is produced by hepatocytes and mediates chemo-attraction of activated lymphocytes expressing the CXCL10-receptor, CXCR3, it is counter-intuitive as to why this chemokine correlates with therapeutic non-responsiveness. The investigators hypothesized and have now demonstrated that CXCL10 is being cleaved in situ, resulting in the generation of an antagonist form of the chemokine. Based on the use of specific inhibitors, the investigators now propose to test whether protection of the agonist form of CXCL10 will increase responsiveness to peg-IFN-alfa2 / ribavirin therapy. This can be achieved using DPPIV inhibitors, targeting the enzyme responsible for N-terminal truncation of CXCL10. If safety is confirmed, the efficacy of DPPIV-inhibition in HCV patients will be tested in future trials that examine potential clearance benefits.
