Filter by:This is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of albumin interferon alfa 2b (alb-IFN)in combination with ribavirin compared with peginterferon alfa-2a (PEGASYS or PEG-IFNa2a) in combination with ribavirin in subjects with chronic hepatitis C, genotype 1 who are IFNa treatment naive.
The purpose of this study was to investigate the safety, tolerability, pharmacokinetics (PK), and antiviral activity of multiple doses of ACH-0137171 in participants with chronic hepatitis C virus (HCV) infection.
Iron excess is increasingly regarded as an important cofactor in the morbidity attributed to many disorders. Assessment of body iron stores by measurement of serum ferritin concentrations has poor specificity and the most reliable method is histological or biochemical assessment from a liver biopsy. Because liver biopsy is an invasive procedure, imaging methods have been developed to detect and quantify hepatic iron content. The aim of the study is to use a simplified magnetic resonance imaging (MRI) technique to quantify simultaneously iron and fat contents in the liver and to compare the results to the quantification obtained biochemically.
Chronic viral hepatitis C is a frequent liver disease. It is associated with variable degree of hepatic fibrosis. To date, liver histology is still regarded as the gold standard to detect, diagnose and quantify liver fibrosis. This requires to perform a liver biopsy. Severe complications are associated to this procedure in 0.01 to 0.1% of cases. Because of this, the repetition of the biopsy to evaluate the progression of the disease or the response to treatment poses ethical questions. Also, liver biopsy only explore a minimal portion of the liver and liver fibrosis, which is not homogeneous, may be under- or over-estimated. To avoid risks linked to invasive technique and sampling errors associated to liver biopsy, efforts are being made to develop non-invasive technology to detect and quantitate liver fibrosis. In this study we will perform in patients with chronic hepatitis C, serum tests, fibroscan (elastography of liver parenchyma determined by ultra-sounds), and elastography of liver parenchyma by MRI. This study will allow - to determine whether non-invasive tests effectively measure liver fibrosis - to compare each non-invase test with results of liver biopsy - to determine whether a non-invasive test or a combination of non invasive tests may be used to accurately evaluate liver fibrosis in patients with chronic hepatitis C.
Although injection drug users (IDUs) account for over 70% of new cases of HCV infection/year, there is no consensus on how to approach their medical care. In some Canadian centres, patients must be free of recreational drug use for as long as 6 months before being considered for HCV therapy. This is not consistent with current North American guidelines. Over the past 5 years, we have developed a successful program for the treatment of HIV infection in this population, based on a multi-disciplinary comprehensive program including directly observed therapy (DOT). Even though the duration of therapy for HCV is shorter than for HIV (as little as 6 months vs. life-long), we must address issues of administration of a weekly injection (interferon), twice daily pills (ribavirin) and the risk of significant side effects (including anxiety and depression) to successfully expand our program to treat this disease. Further, it may be that even if the program is successful, its benefits will be negated by HCV re-infection due to continued risk behaviors for its transmission.
This study is being conducted to see if the investigational medication, valopicitabine, is safe to use in combination with ribavirin, a drug approved by the FDA for treating hepatitis C infection.
This 4-arm study will compare the efficacy and safety of PEGASYS induction and maintenance dosing, versus standard fixed dosing in combination with Copegus, and the efficacy and safety of higher dose versus standard dose Copegus in combination with PEGASYS. Patients with chronic hepatitis C (CHC) genotype 1 infection of high viral titer, and baseline body weight ≥85 kg, will be randomized to one of 4 groups, to receive one of the following: a) PEGASYS 180 µg subcutaneously (sc) weekly plus Copegus 1200 mg orally (po) daily; b) PEGASYS 180 µg sc weekly plus Copegus 1400-1600 mg po daily; c)PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1200 mg po daily; or d) PEGASYS 360 µg sc weekly (induction) followed by 180 µg sc weekly (maintenance) plus Copegus 1400-1600 mg po daily. Following 48 weeks treatment, there will be a 24-week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
Infection with either HIV or hepatitis C virus (HCV) affects immune system responses. The purpose of this study is to investigate the immune responses to two different vaccine formulations in HIV-infected, HCV-infected, and HCV/HIV- coinfected individuals.
The purpose of this study is to determine whether a six-session, small group behavioral intervention based on "peer-volunteer activism" is effective in (1) decreasing distributive sharing of syringes and other injection paraphernalia and (2) increasing utilization of HCV-related healthcare services among HCV-infected injection drug users
The purpose of this study is to determine the safety and tolerability of different dosages of silymarin on subjects with Hepatitis C or Non-Alcoholic Fatty Liver Disease.
