Active clinical trials for "Hepatitis C, Chronic"

This study will examine viral dynamic responses in subjects with chronic hepatitis C and hemophilia when treated with pegylated interferon + ribavirin and telaprevir.

This is a three-year (except for participants with chronic kidney disease [CKD] or cirrhosis) multicenter study to follow participants who received at least one dose of grazoprevir (MK-5172) in a previous study to determine whether they remain hepatitis C virus (HCV)-Ribonucleic acid (RNA) negative over time, and to determine if they have developed antiviral resistance. The study will also evaluate long-term adverse events in this population. Participants from MK-5172-052 (NCT02092350) with CKD or cirrhosis will be followed for five years.

This multicenter, observational study will assess the efficacy and the safety of Pegasys (peginterferon alfa 2a) in dual- or triple therapy in patients with chronic hepatitis C. Patients will receive Pegasys and/or ribavirin and/or a protease inhibitor according to local guidelines. Data will be collected for 96 weeks.

This prospective observational study will evaluate the efficacy and safety of two approved pegylated interferon-based direct acting antiviral triple therapies in patients with chronic hepatitis C genotype 1. Patients receiving pegylated interferon (e.g. Pegasys) and ribavirin plus either telaprevir or boceprivir in accordance with local standard of care and US labeling will be followed for the duration of their treatment and for up to 24 weeks post-treatment.

This prospective observational study will assess the insulin resistance and its impact on sustained virological response in patients with hepatitis C treated with Pegasys and Copegus. Data will be collected from each patient during the up to 72 weeks of treatment and for 24 weeks of treatment-free follow-up.

This observational study will evaluate the predictive value of rapid virological response (RVR) and early virological response (EVR) on sustained virological response (SVR) by stage of liver fibrosis in treatment-naïve patients with chronic hepatitis C genotype 1 initiated on treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will be followed for 48 weeks of treatment and up to 24 weeks of follow-up.

The efficacy of combination antiviral therapy for chronic hepatitis C is influenced by many factors. Important patient-specific factors include, age, gender, race, body weight. Important virus-specific factors include HCV genotype and serum HCV RNA level. Finally, important treatment-related factors include the type of interferon, dose of ribavirin and the duration and adherence to treatment. Despite the importance of patient- and virus-specific factors, the most important indicator of treatment success is a rapid, profound and sustained decrease in serum HCV RNA levels after the start of treatment. The on-treatment virological response can thus be used to predict the probability that a given patient will achieve an SVR if they remain on therapy. It can also be used to individualize the duration of treatment. In this study, treatment for patients with chronic hepatitis C was individualized on the basis of clinical characteristics and the on-treatment virological response. The aim was to investigate the usefulness of undetectable HCV RNA levels at week 4 (RVR) and 12 in tailoring the duration of treatment and predicting SVR in Chinese patients with chronic hepatitis C.

The primary purpose of this study is to determine whether the hepatitis C virus continues to remain unable to be detected in subjects who were previously treated with Asunaprevir (BMS-650032) and/or Daclatasvir (BMS-790052) and achieved sustained virologic response.

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Kuwait in a clinical practice patient population.

In this Slovenian, multi-center, observational study, the effectiveness of standard of care Peginterferon alfa-2a + ribavirin treatment in adult patients with chronic hepatitis C (CHC) is examined. Patients were treated for 24- or 48-weeks, as prescribed by the treating physician, followed by a 24-week follow-up period.
