Active clinical trials for "Hepatitis C"

This study will evaluate the effect of sofosbuvir (SOF)/velpatasvir (VEL)/voxilaprevir (VOX) fixed-dose combination (FDC) + voxilaprevir on the pharmacokinetics (PK) of a representative hormonal contraceptive medication, norgestimate/ethinyl estradiol (Ortho Tri-Cyclen® Lo (OC)) and will assess the effect of norgestimate/ethinyl estradiol on the PK of SOF/VEL/VOX+VOX.

The purpose of this study is to assess the safety, tolerability, and efficacy of Sofosbuvir containing regimens in treatment-naive or treatment-experienced patients with HCV genotype 3 infection.

This is an open-label, two-group, fixed-sequence study to evaluate the effect of ACH-3102 and Simeprevir on AL-335 pharmacokinetics in healthy volunteers.

The primary objective of this pilot trial is to evaluate the feasibility of 12 weeks vs. 24 weeks of field-based directly observed therapy (DOT) for HCV therapy in a resource-limited setting. The investigators will compare treatment completion rates among 50 persons chronically infected with HCV who will be randomized to receive either 1) 12 weeks of sofosbuvir (SOF) + ribavirin (RBV) + pegylated interferon alfa-2a (PEG); or 2) 24 weeks of SOF + RBV. Treatment will be delivered daily by field workers at a location of a participants choosing. Secondary objectives are 1) To compare the efficacy of SOF+RBV with or without PEG as measured by the proportion of subjects with sustained viral response at 12 weeks after discontinuation of therapy (SVR12); 2) To evaluate the safety and tolerability of SOF+RBV with or without PEG; 3) To assess the impact of SVR12 on insulin resistance.

The purpose of the study is to study the combination of Sofosbuvir in Combination With Daclatasvir or Simeprevir for 12 Weeks in Non-cirrhotic Subjects Infected With Chronic Hepatitis C Virus (HCV) Genotype 1.

The aim of the study is to determine if treatment for recently acquired hepatitis C infection (with or without HIV coinfection) can be shortened when treating with the interferon-free therapy sofosbuvir/velpatasvir (SOF/VEL). SOF/VEL is a new treatment for hepatitis C called direct acting antiviral which targets the hepatitis C virus replication cycle and has been shown in phase II studies in chronic HCV to be highly effective (SVR12 >95%) when given for 12 weeks. Data has shown that treatment can be shortened when treating recently acquired HCV with interferon containing treatments. It is not known whether treatment with SOF/VEL can be shortened. This study aims to find out if treatment for 6 weeks with open-label SOF/VEL is equivalent to treatment for 12 weeks with SOF/VEL in participants with recently acquired hepatitis C infection. The project is a randomised study where both participants and investigators would not find out the treatment duration of the participants until week 6 of treatment.

There are now several licensed drug treatments for patients with HCV infection. These medications have been shown to be very effective in getting rid of the virus in patients with HCV infection including those with early stages of cirrhosis without complications known as compensated cirrhosis, with a greater than 90% cure rate. At present, there are very little data to show that treating patients with HCV infection and decompensated cirrhosis will give the same effects. However, patients with decompensated cirrhosis as a result of hepatitis B infection who received treatment to control their virus show improvement of their overall liver condition, and the liver complications of many of these patients disappeared. Also, patients with cirrhosis due to excess alcohol and who stopped drinking also showed improvement in liver function and their complications of cirrhosis coming under control. Therefore, treatment of patients with HCV infection and decompensated cirrhosis is expected to show the same positive effects, because the underlying cause of cirrhosis is coming under control. Harvoni is a combination of two direct-acting antivirals (ledipasvir and sofosbuvir) that prevents the hepatitis C virus from copying and multiplying themselves, allowing the body to clear the virus from their systems and be cured of HCV infection. This study is being conducted to find out if treatment with Harvoni will lead to clearance of HCV infection in patients with decompensated cirrhosis giving rise to improvement in liver function, together with improvement of quality of life and survival.

Current treatments for Hepatitis C virus (HCV) have severe side effects and are very expensive. There is a need to explore effective natural therapies against HCV that are less toxic and more cost-effective. 37 chronic HCV infected patients were randomized into two groups and treated with PEG interferon plus ribavirin for the first group or Biobran, an arabinoxylan from rice bran (1 g/day) for the second group. Viremia level, liver enzymes, γ-interferon (IFN-γ) levels in serum, and toxicity were checked before and three months after treatment.

This randomized, double-blind study will assess the safety, pharmacokinetics and efficacy of a single and multiple dose(s) of orally QD administered EDP-494 in healthy volunteers (HV) and in treatment-naive subjects with GT1/3 chronic hepatitis C (CHC) infection.

The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without sofosbuvir (SOF) and ribavirin (RBV) in DAA treatment-experienced adults with Genotype 1 Chronic Hepatitis C Virus infection. This study will contain 2 parts. Part 1: Approximately 20 participants and at least 10 of the 20 participants previously treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir, with or without RBV, and experienced treatment failure. Part 2: Approximately 10 participants and all participants previously treated with SOF/ledipasvir and experienced treatment failure.
