Active clinical trials for "Hepatitis C, Chronic"

To explore the effect on early viral kinetics and viral load, and to determine safety, tolerability and anti-viral response for the plasmid DNA vaccine CHRONVAC-C administered i.m. in combination with electroporation followed by standard of care (SOC) in treatment naïve chronic HCV genotype 1 patients.

Chronic hepatitis C virus (HCV) infection is associated with an increased risk for the development of type 2 diabetes and HCV infection itself may promote insulin resistance, irrespective of the severity of liver disease. Insulin resistance seems to be genotype specific and may play a role in fibrogenesis in chronic hepatitis C. In an "in vitro" model, increased levels of insulin may promote increased HCV replication. RATIONALE Decreased insulin resistance and reduced hyperinsulinemia may facilitate the efficacy of anti-viral drugs on HCV replication.

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.

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.

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.

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

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

This study is evaluating the safety and efficacy of a 12 week treatment LDV/SOF FDC in patients with Chronic GT1 or GT4 HCV infection and autoimmune disease

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.

Patients with HCV genotype 1 and IL28B CC Polymorphism who have a rapid virological response to treatment are randomised to either 24 or 48 weeks HCV treatment. Our hypothesis is that there is no important difference in effect between the two treatment effect.
