Active clinical trials for "Hepatitis C"

This study seeks to provide evidence of the effectiveness and obtain patient reported outcomes (PRO) and work productivity data of the interferon-free regimen of paritaprevir (PTV)/ritonavir (r) + ombitasvir (OBV), +/- dasabuvir (DSV), +/- ribavirin (RBV) in chronic hepatitis C virus infected patients.

The interferon-free combination regimen of ombitasvir/paritaprevir/ritonavir/ 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 was the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Belgium in a clinical practice patient population.

This study will evaluate the safety and efficacy of sofosbuvir (SOF)-based regimens administered as per the approved prescribing information in adults with chronic hepatitis C virus (HCV) infection treated in routine clinical practice in India.

The purpose of this study is to determine the rate of kidney or heart impairment, if any, in subjects who received BMS-986094 (INX-08189) in Phase 1 clinical trials

The standard treatment of chronic hepatitis C infection is pegylated interferon alpha combined with ribavirin. Anaemia is a common complication occurring in up to 30% of subjects. Unfortunately, side effects of interferon and ribavirin therapy can require dose reductions, reducing the likelihood of sustained viral response. Recent data shows that interferon alpha may increase hepcidin (a key iron regulator) production, resulting in impaired iron availability for production of red blood cells. In this study, we will evaluate hepcidin levels in 30 patients with Hepatitis C who are treated with interferon containing regimes. If hepcidin plays a role in interferon-induced anaemia, cheap and readily available oral hepcidin inhibitors could be trialled to potentially reduce the impact of interferon alpha induced anaemia.

Description: A randomized Placebo-controlled study to evaluate safety and efficacy of Cenv3 peptide vaccine in normal volunteers. This study is designed to test safety of 3 consecutive monthly escalating doses of the immunogen ( 0.324 mg, 0.648 and 3.240 mg / 70 kgm body weight) in 40 healthy male subjects (15,15 and10 subjects respectively) plus 10 subjects on placebo. Bioavailability of Cenv3 will be tested throughout the duration of the experiment. In the study hyperimmune state will be achieved via 3 subcutaneous injections (0.648 mg each), once every 4 weeks. A placebo treated healthy subjects ( n= 10) will serve as controls. Chronic HCV patients ( n=50) who did not respond to IFN + RBV combined therapy will be recruited to test therapeutic efficacy of the compound via 6 consecutive injections ( 0.648 mg each ) every 2 weeks. ( NB : this group of patients has been already recruited in the first part of this project where evaluation of the compound is currently underway). Immunized healthy volunteers will be followed for a year compared with placebo group, where all biochemical, hematological, immunological and allergic parameters are recorded. Treated CHC patients will be evaluated for virological, hematological, biochemical and immunological states at the end of treatment. Subject : Cenv3 potential prophylactic and therapeutic immunogens in healthy volunteers and against chronic HCV infection respectively.

HCV infection is the most frequent cause of liver chronic disease, cirrhosis and hepatocellular carcinoma in western countries. To date, the standard antiviral treatment, including pegylated interferon (PEG-IFN) plus ribavirin (RBV), has relatively low effectiveness in patients infected with genotype 1 and 4, and is associated with important adverse side effects, that lead to treatment interruption in approximately 30% of cases. The recent association of first generation HCV- specific direct-acting antiviral agents (DAAs) (telaprevir and boceprevir) to standard treatment has resulted in higher SVR rates, also in patients infected with genotype-1 HCV and in non responders to PEG-IFN plus RBV. While several new DAAs are in development, the ultimate goal is represented by IFN-free regimens, that will provide a great advantage in terms of patients adherence to therapy and quality of life. In this context, prospective observational studies are needed to evaluate the real and long-term impact of the new DAAs in the clinical practice, in terms of efficacy, safety, costs and impact on patients quality of life. Italy is the European country with the greatest number of HCV infected people (average, 3% of population), with higher prevalence in the center and in the south of the country, especially in older individuals, and the highest mortality caused by hepatocellular carcinoma. Genotype 1 is the most frequent one (in more than 50% of infected people). DAAs were approved at the end of 2012. For these reasons, Italy represents an interesting context for collecting data on long-term efficacy, safety and tolerability of new anti-HCV treatments. The PITER cohort study, developed in the frame of Italian Platform for the study of the therapy of viral hepatitis a prospective observational study, is based on a large cohort of HCV infected patients from more than 100 clinical centers distributed on the whole national area. The main aims of the PITER longitudinal cohort study are: 1) to produce of an ongoing and continuously updated picture of the changing epidemiology of HCV infection in the country; 2) to evaluate in a real-life setting the expected impact of DAAs on the natural course of infection and on long-term morbidity and mortality.

Objectives: 1) To evaluate la proportion of hepatitic C virus (HCV)-monoinfected patients who show sustained virologic response (SVR) to treatment including direct-acting antivirals (DAAs) in the clinical practice in clinical units that treat infectious diseases and 2) to determine the frequency of adverse events, including those that are severe and/or cause treatment interruption, in DAA-based therapy in this setting. Design: Multicentric, prospective post-authorised cohort study. Setting: Hospitals of the Hepatitis Study Group (GEHEP) of the Spanish Society of Infectious Diseases and Microbiology (SEIMC). Study population: HCV-monoinfected patients that initiate DAA-based treatment outside clinical trials. Variables: The primary efficacy outcome variable is the proportion of patients who reach undetectable HCV-RNA 12 weeks after the scheduled end of therapy (SVR12). The primary safety outcome variable is the percentage of subjects who discontinue therapy due to adverse events. Statistical analysis: A descriptive study will be performed, as well as a double sensibility analysis of the frequency of SVR12 using both an intention-to-treat and an on-treatment approach. Those variables that are associated with SVR12 with a p-value <0.2 will be included in a logistic regression analysis in which SVR12 will be the dependent variable.

The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States (US) is relatively low. However, immigrant populations in the US from Asia and sub-Saharan Africa have substantially higher prevalence than the general population and are consequently at a significant risk for hepatocellular carcinoma (HCC). Indeed, the age-adjusted incidence rates for HCC in the US have tripled from 1975 to 2005. As the population demographics have changed, the 2000 US census estimated the number of Somalis in Minnesota at 25,000 but current estimates put the number at around 50,000 due to primary refugee arrivals as well as secondary immigration from other states. There is no available data for Somali immigrants in the US on HBV and HCV prevalence, HBV and HCV genotypes/subgenotypes, and genetic and immunologic risk factors predisposing Somalis to HBV and HCV and the subsequent development of HCC. Therefore. this study will fill these gaps in the Somali population to understand the relative importance of HBV and HCV infections in causation of HCC. Besides Somalis, Minnesota is also home to large other African immigrant communities. According to the Minnesota Department of Health (MDH), in 2013, the highest rates of chronic HBV cases where reported among Asian or Pacific Islanders (3,638 cases per 100,000 persons) followed by Black or African Americans (2,078 cases per 100,000 persons). Additionally, Minnesota receives a large number of new refugee's resettlement. It is important to improve the identification of chronic HBV and HCV infections among Somali refugees and immigrants in Minnesota through well-designed community-wide screening efforts. Since we know that African immigration to Minnesota is the third highest in the US, this unique population might be a contributing factor to the increased burden of hepatitis and liver cancer complications in the state of Minnesota. Findings from HBV and HCV screening among Somalis suggest that other immigrant African populations from high viral hepatitis endemic regions, such Ethiopia, Liberia, and Kenya, are also at substantial risk of HBV, HCV and HCC. Unfortunately, very little research has been conducted in the US on the burden of hepatitis and liver cancer in African Immigrants from areas of high endemicity of hepatitis B and hepatitis C. Therefore, the goal of is to identify HBV and HCV and the role viral genetics and immune response among African immigrant communities from Kenya, Liberia, and Ethiopia.
