Active clinical trials for "Hepatitis C"

Background: - Chronic hepatitis C is a serious liver disease. Current treatments have side effects. New drugs have been developed, but they work better in some people than others. Researchers want to learn why. Objective: - To learn why new hepatitis C drugs sometimes do not work. Also, to learn if these drugs are safe and how well they work in people with different virus strains. Eligibility: - Adults age 18 and older who are infected with hepatitis C virus genotypes 1-4 and who have either never been treated or treated previously with an interferon regimen (with or without ribavirin) that failed to clear the virus. Design: Participants will be screened with medical history and physical exam. They will have blood and urine tests and complete questionnaires. Participants will have a Fibroscan, an ultrasound that measures liver stiffness and other liver scans. They will have an electrocardiogram. Eligible participants will have a liver biopsy. Participants will be admitted to the Clinical Center. They will have a physical exam and blood tests, and complete questionnaires. They will take the first study drug dose as a tablet taken once daily. Participants will take the drug at home for 12 weeks. Participants will have 6 study visits. They will have blood and vital signs taken, and complete questionnaires. At week 4, participants will have another liver biopsy. After their last drug dose, participants will have 5 follow-up visits. They will have blood and vital signs taken, and complete questionnaires. They will discuss their medications and side effects. They may have another Fibroscan.

The primary objectives of this study are to assess the safety and the SVR12 rate of ombitasvir/paritaprevir/ritonavir and dasabuvir with RBV in GT1-infected participants with decompensated cirrhosis.

Camel milk as the new modality for treatment of chronic hepatitis C. The purpose of this study is to evaluate effectiveness and safety of camel milk in combination with Peginterferon Alfa-2a and Ribavirin in genotype 2,3 chronic hepatitis C virus .

This was a multicenter study evaluating the efficacy and safety of ombitasvir/paritaprevir/ritonavir and dasabuvir co-administered with ribavirin (RBV) for 12 weeks in treatment naïve and pegylated-interferon alfa-2a or alfa-2b (pegIFN)/RBV treatment-experienced, cirrhotic HCV genotype 1b-infected adults.

The purpose of this study is to determine the efficacy of a 12- or 24-week treatment regimen of simeprevir in combination with daclatasvir, as measured by sustain virologic response 12 (SVR12), in treatment-naive, chronic hepatitis C virus (HCV) genotype 1b-infected participants who have advanced fibrosis or compensated cirrhosis (METAVIR F3/F4).

To assess the antiviral effect, safety and pharmacokinetics of rising doses of 10 mg, 20 mg, 40 mg, 60 mg, 80 mg, 100 mg, 150 mg, 200 mg, 300 mg, 450 mg, 650 mg, 900 mg oral BILB 1941 ZW administered Q8H in a polyethyleneglycol 400 (PEG 400): distilled water: Tromethamine (TRIS) drinking solution for five days to patients with chronic HCV genotype 1 infection

The purpose of Part 1 is to inform dose selection for use of alisporivir and EDP239 in combination and obtain initial safety data for co-administration of alisporivir and EDP239 to support future treatment studies in patients. The purpose of Part 2 is to inform the drug-drug interaction potential of EDP239 more broadly and possibly facilitate the interpretation of lower than expected alisporivir concentrations in Part 1, if observed.

This open-label study will evaluate the safety and efficacy of co-formulated ombitasvir/paritaprevir/ritonavir and dasabuvir co-administered with sofosbuvir with or without ribavirin administered for either 4 or 6 weeks in treatment naive adults with chronic HCV-genotype 1 infection without cirrhosis

The primary objective of this study is to evaluate the pharmacokinetics, safety, and tolerability of voxilaprevir (formerly GS-9857) in participants with severe renal impairment and matched healthy control participants.

The primary objectives of this study are to evaluate the antiviral efficacy of therapy with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) and to evaluate the safety and tolerability of LDV/SOF FDC and sofosbuvir (SOF) + ribavirin (RBV) in participants with chronic genotype 2 hepatitis C virus (HCV) infection.
