Active clinical trials for "Hepatitis C"

The main objective of this study is to assess whether a recently-developed bioassay for the molecule "secreted fibrinogen-like protein 2" (sFGL2) can be used to predict the recurrence and/or progression of Hepatitis C Virus disease in post liver transplant patients. The hypothesis is that patients with chronic HCV have higher than normal levels of sFGL2 in their blood both pre- and post-transplantation and that this will inhibit their ability to clear HCV, and influence the progression of HCV disease when it recurs.

The primary goal of hepatitis C virus (HCV) Direct Acting Antivirals (DAAs) is to achieve undetectable HCV RNA in the blood. A response that should be maintained for at least 12 weeks from completion of therapy. This is called sustained virological response (SVR) which corresponds to cure of HCV infection as risk of later relapse is very small. SVR is important to achieve improvement in liver necroinflammation and fibrosis and to decrease complications of cirrhosis. Failing to achieve SVR after treatment requires another regimen for these experienced patients. Real-world data are always needed to evaluate and improve our practices. Here investigators aim to assess tolerability and efficacy of different regimens used for management of genotype 4 HCV relapse.

Successful treatment of hepatitis C has been reported to be associated with 62-84% reduction in all-cause mortality (deaths), 68-79% reduction in risk of HCC and 90% reduction in risk of liver transplantation. The efficacy of NS5A inhibitors for the treatment of patients chronically infected with hepatitis C virus (HCV) can be affected by the presence of NS5A resistance-associated substitutions (RASs). Pre-existence of resistance associated substitutions (RASs) to direct antiviral agents (DAAs) reduces sustained virologic response (SVR) rates by 3-53% in hepatitis C virus (HCV) genotype 3 infected patients depending on different predictors and the DAA regimen used. This study will prospectively analyze data from the MukhMantri Punjab Hepatitis C Relief Fund (MMPHCRF) to determine the posttreatment prevalence of various NS5A RASs, and their effect on outcomes of treatment with daclatasvir-sofosbuvir or sofosbuvir-ledipasvirin patients with chronic HCV. The study aims to assess the prevalence and effect of RASs on sustained virological response (SVR) rates in patients with treatment failure to a regimen containing sofosbuvir and ledipasvir/daclatasvir.

The primary objective of this study is to prospectively analyse psychiatric outcomes, specifically depression and anxiety in patients with hepatitis C virus infection who are initiated on DAA therapy (sofosbuvir based regimen).

To evaluate the efficacy, adverse effect, short - and long-term outcomes of Glecaprevir/Pibrentasvir for the treatment of chronic hepatitis C (non-cirrhotic or compensatory cirrhosis)in China through a real-world study

To evaluate the efficacy of a new screening for infectious diseases: tuberculosis, HIV, HBV and HCV, based on risk factors questionnaires (TB screen for tuberculosis and TROD screen for HIV and hepatitis) amongst a population of legal migrants during their mandatory medical check-up. This study aims for a global improvement of screening and care for migrants.

The main purpose of the CoDISEN cohort study is to propose a model of prevention and care for HIV and viral hepatitis adapted to the needs of people who inject drugs (PWID) in Dakar, Senegal.

The investigators aim to assess the effectiveness and safety of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) for 12 weeks in hepatitis C virus (HCV)-infected patients who fail to prior NS5A-containing DAA regimens and HCV genotype 1a and 3 patients who fail to prior non-NS5A-containing DAA regimen in Taiwan on a basis of a multicenter observational study.

The aim of the present study is to estimate the national annual prevalence and incidence of current hepatitis C virus (HCV) infections among opioid dependent individuals in opioid substitution treatment (OST) based on a representative sample of approximately 2,500 outpatients in 100 substitution facilities across Germany. Furthermore, the study aims to describe factors influencing HCV therapy initiation and seroconversion during OST.

The investigators will identify possible participants using our database of previously treated hepatitis c patients. The investigators will identify those who have documented evidence of current injecting drug use as a risk factor for acquisition of the virus. The investigators will then search for those who have received curative treatment between 2004-2010. This covers all patients in the current database. The investigators will include those over 18 years old. The investigators will exclude those patients who are coinfected with either hepatitis B or HIV. This is because both of these conditions can accelerate liver damage when in combination with hepatitis c. The possible participants identified will be sent an information sheet giving a simple and clear outline of the proposed research. The investigator will try to obtain an au to date residential address from the PAS system in the NHS or through confirmation from the patients GP or drug worker. It will explain the purpose of the study, why they have been chosen, what taking part will involve, the potential advantages and disadvantages of taking part and that everything will be kept confidential. It will also outline who is conducting the study, how any expenses will be paid and contact details for any problems/complaints that arise. Those interested in taking part will attend an appointment at the hospital after they have had the opportunity to read through the information leaflet. They will be given time to ask any questions they have about the study and have them answered fully. They will then be asked to sign two copies of a consent form in order to take their participation any further. Once this is complete they can have their first 'liver assessment'. The assessment will take approximately 30-45 minutes to complete. The investigators will take three blood samples from them (approximately 10mls of blood or 4 teaspoons full). One sample is to measure the levels of hepatitis C virus in the blood. This will tell us whether there has been reinfection with hepatitis C. The second sample is to measure the levels of inflammation within the liver and the third sample is to measure the full blood count. The investigators will then perform a liver scan called a fibroscan. This is a noninvasive test similar to an ultrasound (that pregnant women have) and gives a reading that can tell us about any 'stiffness' in the liver. It takes approximately five to ten minutes to complete and involves the patient lying on their back with their right arm above their head for the duration of the scan. Following the scan the investigators will ask the participant to complete a short questionnaire. This will include questions about past and current drug use as well as any alcohol use. The answers will be kept strictly confidential. They will be stored in the researchers locked office and have no direct participant identifiers on them. They will simply have a study number on them.The participant will then be thanked for their time and offered £30 to cover all travel and time expenses for their visit. They will be invited to attend for a further liver assessment one year after their first one and annually thereafter. This is optional and they are of course free to withdraw from the study at any time without needing to give a reason. The investigators will be identifying participants at different points in time following their curative treatment. For example some will have been cured 5 year ago whereas other will have been cured 6-12 months ago. This will increase the number of patient years follow up. Once the investigators have done the first set of liver assessment the participants will then be followed prospectively for as long as they wish to participate. For the purpose of my higher degree I will present the data I have following two years of 'liver assessments'.
