Active clinical trials for "Hepatitis C"

This was a long-term follow-up study to evaluate the durability of sustained virologic response (SVR), persistence of direct-acting antiviral agent (DAA) resistance, and clinical outcomes for participants who received glecaprevir (ABT-493) and/or pibrentasvir (ABT-530) in prior AbbVie Phase 2 or 3 clinical studies for the treatment of chronic hepatitis C virus (HCV) infection.

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.

The purpose of the OPDEP pilot study is to assess the feasibility of implementing a pre-operative HIV / HCV / HBV screening proposal for all persons over 18 years of age and refer for surgical intervention under general anesthesia in the Department of Stomatology of the Pitié-salpêtrière hospital. Patients undergoing treatment in Stomatology have particular areas at risk for the infections we are looking for: young patients, precarious situation, drug use, migrants ... The aim is to evaluate the conditions for a generalization of screening in the framework of the preoperative assessment.

Recently,surprisingly and unexpectedly increased aggressiveness and high rates of HCC recurrence (28%(16/58) and 29%(17/59), respectively) have been reported in patients who cleared HCV with DAAs after achieving a complete response to resection or local ablation within only 6 months of therapy. The authors hypothesized that the rapid eradication of HCV and control of liver inflammation would impact anti-tumoral immune control, which in turn might contribute to the neoplastic cells proliferation. Conversely, three independent prospective French cohorts failed to reveal an increased risk of HCC recurrence after DAAs treatment in CHC patients after receiving curative cancer treatments.Although the impact of DAAs treatment on the rate of HCC occurrence or recurrence still remain unclear, it would be more important to pay attention to the immunological changes of CHC patients treated with DAAs.Up to now, little was known about the immunological changes of chronic hepatitis C (CHC) patients treated with direct-acting antiviral agents (DAAs), here we try to explore the effect of antiviral treatment of CHC patients with DAAs on the frequency of monocytes, NK cells and cytokines that promote their activation.

The aim of the study is to evaluate in clinical practice the efficacy and safety of ombitasvir/paritaprevir/ ritonavir and dasabuvir administered for 8 weeks in treatment-naïve participants with genotype 1b hepatitis C virus (HCV).

Chronic hepatitis C infection is a global worldwide health problem with an increasing burden year-by-year, particularly in areas with a high endemicity like Egypt . The World Health Organization estimates that approximately 200 million people worldwide are infected with hepatitis c virus. In Egypt, it was estimated that 15 % of Egyptians have serologic evidence of hepatitis C viral infection .

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

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 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.
