Filter by:Genotype 1 CHC participants from Study SPC3649-207 with null response to prior pegylated-interferon alpha plus ribavirin will be enrolled into this 36-month extension study, designed to evaluate the long-term safety and efficacy after 12 weeks of miravirsen monotherapy. Due to the observational nature of the study, miravirsen will not be dosed as an investigational product.
To evaluate the effect of ribavirin on second phase plasma hepatitis C virus (HCV) ribonucleic acid (RNA) decline in participants who receive ombitasvir/ABT-450/ritonavir and dasabuvir with full dose ribavirin, low dose ribavirin or without ribavirin for 2 weeks in treatment-naive HCV genotype (GT) 1a-infected adults.
A study to evaluate immune restoration following removal of viral antigen in non-cirrhotic hepatitis C virus (HCV) genotype (GT) 1a treatment-naïve and pegylated-interferon (pegIFN)/ribavirin (RBV) treatment-experienced adults receiving treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir coadministered with ribavirin (RBV) for 12 weeks.
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 purpose of this study is to assess the efficacy and safety of ABT-493 and ABT-530 with or without ribavirin (RBV) in participants with chronic hepatitis C virus, (HCV)-infection who previously failed treatment with a direct acting antiviral (DAA)-containing regimen.
The purpose of this study is to evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin in US veterans with genotype 1 chronic hepatitis C virus infection.
The purpose of this study is to evaluate the effects of sustained virological response in liver and spleen stiffness in patients with HCV compensated advanced chronic liver disease treated with new all oral antiviral drugs in order to determine factors implicated in stiffness change and its implications for long-term follow-up.
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 study will assess the efficacy of PPI-668 (USAN: ravidasvir hydrochloride) in combination with sofosbuvir, with or without ribavirin, in the following Egyptian HCV gt-4 patient populations: 1. Treatment-naïve patients, with and without cirrhosis (Group 1) 2. Previous non-responders to interferon-based therapies, without cirrhosis (Group 2) 3. Previous non-responders to interferon-based therapies, with cirrhosis (Group 3)
This randomized, double-blind, placebo-controlled, 3-part study will assess the safety, tolerability, and pharmacokinetics of orally administered AL-335 in healthy volunteers (HV) and subjects with CHC infection.
