Filter by:The Chinese patients with chronic hepatitis C have a different genetic background, which had been demonstrated to significantly influence their responses to pegylated interferon and ribavirin. In this study, Chinese patients with Hepatitis C Virus genotype 1, 2/3, 6 infection were treated with pegylated interferon and ribavirin. Their response was compared amongst different genotypes.
This will be a Phase I-II, open-label, single center, uncontrolled, dose-escalation study. The trial will be conducted in Israel at the Tel Aviv Sourasky Medical Center. All subjects will receive autologous InfraDure Biopump (micro-organ of dermis processed ex vivo transduced with genetic construct containing the gene for interferon)tissue implants intended to provide sustained production and delivery of therapeutic levels of INF for up to twenty four (24) weeks following INFRADURE Biopump implantation. Follow up will continue for a total of two years post INFRADURE Biopump implantation
This is a research study to evaluate the safety, tolerability and anti-viral activity of GS-9669 in patients with Hepatitis C infection.
Patients who completed the conventional treatment against HCV and relapsed (the virus appeared again in their blood) have no effective therapy.
This multi-center study will evaluate the viral response in patients with chronic hepatitis C, genotype 1, 2, 3 & 4 on standard anti-viral treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will receive weekly subcutaneous Pegasys plus daily oral Copegus for 24 weeks (genotype 2 & 3) or 48 weeks (genotype 1 & 4). Patients identified as slow responders/non-rapid virological responders will be eligible for an additional 24 weeks of treatment.
Hepatitis C is the leading cause of liver transplants in the USA. Given that there is a national organ shortage, living donor liver transplantation has became a viable option for patients with end stage liver disease who are not severely ill. Recently particular polymorphisms of IL-28B gene were reported to correlate with histological recurrence and antiviral treatment response after orthotopic liver transplantation for hepatitis C. Similar results have not been described yet in living donor liver transplant patients. There is data suggesting slightly inferior outcomes in living donor liver transplants when done for hepatitis C. The investigators postulate that such inferior outcomes may be related to IL28 polymorphism concordance (i.e., unfavorable recipient polymorphism patients receive similarly unfavorable polymorphism livers from their relatives).
Acute cellular rejection is relatively common after liver transplantation, typically does not affect graft survival, and is not associated with the development of chronic rejection. Acute cellular rejection is diagnosed when liver enzymes and/or liver function tests are elevated when compared to baseline. The only means of differentiating acute rejection from other liver pathologies is with a liver biopsy. However, even with this invasive diagnostic procedure, it may be difficult to distinguish acute rejection from another disease process, such as injury caused by the hepatitis C virus (HCV) from the native liver. This study will evaluate whether certain patterns of biomarkers in the peripheral blood and/or liver tissue of a liver transplant recipient can be used to determine if the transplanted liver is being rejected by the recipient or sustaining HCV injury. Diagnostic biomarkers that are specific for acute rejection and informative of the severity of HCV recurrence could allow for modulation of immunosuppression therapy and treat the clinical condition without the need for invasive liver biopsies.
The purpose of this study is to provide anti-HCV drugs to +/- 200 subjects treated in prior BMS studies with placebo + Peginterferon Alfa-2a and Ribavirin and determine if the addition of these drugs can result in higher cure rates in patients who previously failed therapy. Approximately 100 genotype 1b subjects rolling over from BMS study AI447-028 who received placebo will be treated with active drugs in this study.
The investigators believe that boceprevir's drug concentrations will be reduced when administered in combination with etravirine. The investigators believe that etravirine's drug concentrations will be increased when administered in combination with boceprevir. Additionally, the investigators believe that boceprevir and etravirine are safe when administered alone or in combination.
This is a Phase 4, descriptive, observational, open, prospective study of patients who their doctor prescribes INFERGEN for clinical practice. No medication was provided by the sponsor. The planned observation time is 48 weeks and 24 weeks of follow-up. Each investigator participating in this registry will employ his or her discretion and standard clinical practice to determine when to see the patient in the clinic, how to manage the patient's drug regimen, and how best to monitor the patient's response and tolerance to therapy.
