Active clinical trials for "Hepatitis C"

Investigators aim to study the effect of direct acting antiviral agents (DAAs) on behavior of hepatocellular carcinoma (HCC) and overall survival in patients with chronic hepatitis C (CHC).

This use-results post-marketing surveillance (PMS) study for Sovaldi® tablets (sofosbuvir, SOF) administered in combination with Rebetol® capsules (ribavirin, REB) will evaluate the safety and efficacy of SOF administered in combination with ribavirin under real world use in Japan. Among adult patients with chronic genotype 2 hepatitis C virus (HCV) infection and treated with SOF+ribavirin in routine clinical use, the primary objective of this study is to evaluate the incidence of adverse drug reactions (ADRs) under real world settings.

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.

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 Germany 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.

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 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.

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 study aims to collect information on the current treatment patterns for Hepatitis C in participating countries. There is also a focus on patients receiving a daclatasvir-containing treatment regimen who will be followed prospectively for 12 months after treatment initiation to collect real-world data on effectiveness and safety of the treatment. Additional analysis will differentiate between selected subpopulations.

Since success of the combination therapy with PEG-IFN and RBV is contingent on maintaining adequate doses of both drugs throughout the treatment period, the emergence of hematological side effects is expected and requires intervention. The hematological adverse effects lead to a trade-off between continuing the treatment with optimal dosage, to clear the virus, exacerbating thereby the side effects versus decreasing dosage to relieve severe anemia, reducing thereby the chances of achieving sustained virological response (SVR). Therefore, we aimed at giving Folic acid® and Neurobion® to HCV-infected patients during treatment with different types of PEG-IFN plus ribavirin in an attempt to evaluate its efficacy and safety as a prophylactic treatment to prevent hematological adverse effects. Preventing adverse effects without interfering with the therapeutic efficacy of different types of PEG-IFN plus ribavirin in HCV patients will lead to better health outcomes and improvement in their quality of life (HRQOL).
