Filter by:The purpose of this study is to determine the antiviral effect following three days of dosing with BMS-824393 in chronically genotype subtype 1a and 1b Hepatitis C virus (HCV) infected subjects.
The purpose of this study is to evaluate the safety, tolerability and antiviral efficacy of telbivudine by maintained suppression of hepatitis B virus (HBV) DNA (<=300 copies/ml or 60IU/ml, undetectable by current polymerase chain reaction (PCR) - based assays) in HBeAg positive/negative patients at physician's general practice.
SCV-07 (γ-D-glutamyl-L-tryptophan) is a new immunomodulatory compound that has been developed and patented both for composition and immunomodulatory use and is a synthetic dipeptide. The efficacy of SCV 07 in treating chronic hepatitis C virus (HCV) infection is expected to arise from the drug's ability to stimulate the T-helper 1 (Th1) type immune response and to block signal transducers and activator of transcription 3 (STAT3) mediated signaling. The purpose of this study is to determine if SCV-07 alone and/or SCV-07 in combination with ribavirin is safe and potentially effective for the treatment of genotype 1 compensated chronic hepatitis C in subjects who have relapsed after a response to a previous treatment course of at least 44 weeks with pegylated interferon and ribavirin. All subjects will receive 4 weeks of SCV-07 (Lead-in Phase), followed by 4 weeks of treatment with SCV-07 in combination with ribavirin (Combination Treatment).
This open-label, randomized, parallel-arm study will assess the early immunologic response in treatment-naïve Asian male patients with chronic hepatitis B after initiation of treatment with Pegasys or tenofovir or Pegasys plus tenofovir. Patients will be randomized to one of 4 cohorts to receive either Pegasys (360mcg subcutaneously weekly) or tenofovir (300mg orally daily) or both or no treatment for 2 weeks. After 2 weeks on study treatment, patients may opt to receive standard of care treatment with Pegasys. Target sample size is <50.
The purpose of this study is to demonstrate the relative bioavailability of Ribavirin 200 capsules and Rebetol 200 mg capsules in females under fasting conditions.
The purpose of this study is to demonstrate the relative bioavailability of Ribavirin 200 capsules and Rebetol 200 mg capsules in females under non-fasting conditions.
Background: According to recent estimates, the prevalence of Chronic Hepatitis C (CHC) in Canada is three times more common in First Nations (FN)and Metis compared to non-FN populations. Moreover, once infected, the progression of CHC to cirrhosis and/or hepatocellular carcinoma is greater in FN patients due to the increased prevalence of alcohol abuse, obesity and diabetes in this segment of the population. Research Plan: This research proposal consists of three parts. The objective of Part I is to document the response to anti-viral treatment for CHC among treatment-naïve FN and Metis and Caucasian (hereafter referred to as non-FN) patients residing in three urban Western Canadian centres (Winnipeg, Saskatoon and Regina). Demographic, clinical and response to treatment data in a total of 160 patients (80/group) will be collected at the above centres and transferred to the Section of Hepatology at the University of Manitoba for statistical analyses. In Part II, the applicants will document and compare the immune responses to HCV proteins throughout the course of therapy in FN, Metis and non-FN patients. In the final part, direct economic costs of CHC care in FN, Metis and non-FN patients will be ascertained and future costs predicted. Hypotheses: Part I - The rate of sustained virologic response (SVR) to treatment for CHC is higher in FN and Metis compared to non-FN and no Metis patients. Part II - The immune response to HCV proteins during anti-viral therapy for CHC is enhanced in FN and Metis compared to non-FN and non-Metis patients. Part III - The direct costs of health care utilization and delivery for CHC are similar among FN and Metis and non-FN and non- Metis patients.
The study aimed to investigate the short-term efficacy and long-term prognosis of liver failure patients caused by hepatitis B after single transplantation with autologous marrow mesenchymal stem cells (MMSCs). Liver failure inpatients caused by hepatitis B were recruited and received the same medical treatments, among whom some patients underwent single transplantation with autologous MMSCs and other patients with matched age, gender and biochemical indexes [alanine aminotransferase (ALT), albumin (ALB), total bilirubin (TBIL), prothrombin time (PT) and Model for End-stage Liver Disease (MELD) ] were in control group. A total of 120 ml bone marrow were obtained from patients, diluted and separated. Then MMSCs suspension were slowly transfused into the liver through the proper hepatic artery by interventional procedures. The levels of ALB, TBIL, PT and MELD score of patients in translation group were compared with those in control group. In 3 ~ 48 months of follow-up, differences in long-term outcomes such as incidence of HCC (hepatocellular carcinoma) and mortality between two groups were compared.
Treatment of patients with chronic hepatitis C infected with genotype 1 hepatitis C virus (HCV) consists of combined peginterferon/ribavirin for 48 weeks. Approximately 50% of patients experience sustained virological response which equals cure. All other patients either do not respond or experience recurrence of HCV virus and chronic hepatitis. Important predictors of successful treatment are sustained dosing of both peginterferon and ribavirin. With regard to the latter, clinical evidence indicates that higher ribavirin doses may in fact even improve treatment outcome. However, high ribavirin doses cause hemolytic anemia which require dose reductions. Recent clinical experience show that erythropoetic growth factors, including erythropoetin, can counteract hemolytic anemia caused by antiviral treatment in chronic hepatitis C patients. Therefore, the current trial aims to test whether higher ribavirin doses adapted to a target plasma concentrations instead of a weight-based dosing result in better healing rates, and whether ribavirin-associated hemolytic anemia can be compensated by concommitant erythropoetin treatment. Using a randomized, controlled, open-label design, the investigators hypothesize that patients with high ribavirin doses adapted to plasma levels experience better viral clearance than patients treated with standard weight-based ribavirin doses. In addition, the investigators hypothesize that erythropoetin treatment will counteract hemolytic anemia induced by ribavirin thereby allowing maintenance of target plasma concentrations without ribavirin dose reductions.
This 2 arm open-label study will assess the safety and tolerability of combination treatment with Peginterferon alfa (Pegasys) and Ribavirin (Copegus) in patients with chronic hepatitis C. Patients will be assigned to receive Peginterferon alfa (Pegasys) 180 mcg sc once a week and Ribavirin (Copegus) 800 - 1200 mg po daily for either 24 or 48 weeks. Allocation to the treatment arms is to the discretion of the investigator (mainly according to genotype). Adverse events will be monitored throughout the study and hematologic parameters every 2 weeks and twice during the 24-week follow-up.
