Active clinical trials for "Hepatitis C"

The literature suggests that there may be an association between hepatitis C and type 2 diabetes mellitus independent of the presence of cirrhosis, the likely mechanism for which is insulin resistance. The prevalence of insulin resistance in patients with hepatitis C is unknown. Furthermore, there are no studies that indicate an increased prevalence of insulin resistance in patients with hepatitis C compared to other etiologies of liver disease. The role that hepatitis C may have in the development of insulin resistance is unclear. The effect of antiviral therapy for hepatitis C virus on insulin resistance has not been addressed. The long-term consequence of insulin resistance is type 2 diabetes mellitus. There is significant morbidity and mortality from type 2 diabetes mellitus in the general population, and similar complications would be expected in patients with hepatitis C and insulin resistance particularly if they develop type 2 diabetes mellitus. Our hypothesis: The prevalence of insulin resistance is increased in patients with chronic hepatitis C compared to chronic hepatitis B. Secondarily, insulin resistance when present in patients with chronic hepatitis C improves with successful antiviral therapy. This study has two phases. The first phase of our study will be to estimate the prevalence of insulin resistance in individuals with chronic hepatitis C without cirrhosis compared to patients with chronic hepatitis B without cirrhosis. The second phase of the study will be restricted to those patients with hepatitis C found to be insulin resistant from phase 1, in the absence of known risk factors for insulin resistance (cirrhosis, diabetes). The effect on insulin resistance of anti-viral therapy to eradicate hepatitis C will be assessed.

The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The other aspect of the study is to assess the effect of GBV-C on the severity of liver disease due to chronic hepatitis C in subjects co-infected with HIV and HCV. This will be done by determining the point prevalence of co-infection retrospectively then following that cohort prospectively. In addition, further individuals will be recruited in a prospective manner.

Ribavirin should be avoided during pregnancy and during the 6 months before pregnancy in both the female and the male sexual partner. If a pregnancy occurs and is reported to the Ribavirin Pregnancy Registry, the Registry will follow the pregnant woman throughout pregnancy. The Registry will also follow the infant until 1 year of age. The goal of the Registry is to learn more about the effects of ribavirin on pregnancy and the risk for birth defects. Pregnant women exposed to ribavirin, either by taking ribavirin (during pregnancy or 6 months before pregnancy) or through a male sexual partner (who took ribavirin during the female partner's pregnancy or during the 6 months before pregnancy), are encouraged to contact the Registry.

The number of hemodialysis patients with chronic renal failure in Japan exceeds 0.3 million and is showing an increasing trend. The rate of infection with hepatitis C virus (HCV) is high in hemodialysis patients, and it has been revealed that the prognosis is poorer in HCV-infected hemodialysis patients compared to uninfected patients; therefore, aggressive therapeutic intervention is required.Investigator previously reported the efficacy and safety of a NS5A inhibitor; daclatasvir and a HCV protease inhibitor; asunaprevir combination therapy for Japanese dialysis patients with genotype 1 HCV infection. However, the duration of the treatment is 24 week, which is quite longer than current standard 12 week therapy . elbasvir/grazoprevir combination therapy is oral anti-HCV 12 week therapy without the use of IFN/ribavirin, and a good therapeutic effect has been reported in Japanese phase II studies . Of note is that these drugs are metabolized mainly in the liver and thus they can be used in patients with chronic renal failure. Recently, David Roth et al reported that the efficacy and safety of elbasvir/grazoprevir combination therapy for patients with hepatitis C virus genotype 1 infection and stage 4-5 chronic kidney disease. In this report, they revealed that elbasvir/grazoprevir combination therapy could achieve SVR rate of 99% in the modified full analysis set. However, no adequate clinical investigation has been performed in Japan, thus far concerning the therapeutic effect and safety of elbasvir/grazoprevir combination therapy in Japanese hemodialysis patients.

This is a proof of concept, single center study for the donation of HCV-positive hearts to HCV negative recipient patients, with preemptive, interventional treatment with 12-16 weeks of grazoprevir and elbasvir (with or without ribavirin) to prevent HCV transmission upon transplantation.

Hepatitis C virus (HCV) infection with around 0.5% and 2.2% prevalence in Iran and world is one of the public health problems resulting in chronic liver disease, cirrhosis and hepatocellular carcinoma. All cases of chronic HCV infections are candidates of treatment to prevent advanced liver diseases. The previous Pegylated-interferon and Ribavirin therapy was not efficient in all cases and results in numerous number of side-effects. Introduction of direct acting antiviral agents (DAAs) such as Sofosbuvir and Ledipasvir make the eradication of HCV possible however these regimens are not affordable and available in developing countries. The generic DAAs are manufactured in many of these countries such as Iran to provide the treatment with reasonable price.

The Mukh-Mantri Punjab Hepatitis C Relief Fund (MMPHCRF) is a public health initiative for prevention and control of hepatitis C in the Punjab state, India. The efficacy of decentralised public health services and safety of 12- or 24-weeks of sofosbuvir (SOF) + ledipasvir (LDV) or SOF + daclatasvir (DCV) with or without ribavirin (RBV) in the treatment of pediatric chronic hepatitis C will be assessed

Study is a non-interventional, prospective, multicenter post marketing surveillance study to determine the safety of daclatasvir based therapy

NPC1L1 is a key transporter in the enterohepatic cycle of cholesterol. Initial in vitro and in vivo data show that blocking this receptor with ezetimibe results in delaying infection in these models. The investigators hypothesize that HCV has an enterohepatic cycle, being secreted in bile and reabsorbed either in the canalicular membrane or in the intestine by association with NPC1L1, following a path similar to the cycle of cholesterol in humans. To prove this hypothesis the investigators propose to assess the effect of ezetimibe treatment in HCV infected individuals undergoing liver transplantation to avoid or delay HCV infection. For this purpose, the investigators propose to administrate ezetimibe 10 mg/d for 12 weeks to 12 patients with chronic hepatitis C infection listed for a liver transplantation.

This is open-label, randomized, multicentre study to compare the efficacy and safety of the 8-week versus 12-week of SOF-RVD combination treatment for non-cirrhotic chronic hepatitis C patients. All the recruited subjects will receive the treatment accordingly and be followed up for 24 weeks following the completion of treatment.
