Filter by:The purpose of this phase 3 study is to evaluate the efficacy and safety of ABT-493/ABT-530 in comparison to sofosbuvir plus ribavirin for 12 weeks in Hepatitis C Virus (HCV) Genotype 2 (GT2) infected participants.
The primary objective of this study is to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection.
The objectives of the study are to determine the impact of interferon-free treatment for the hepatitis C virus (HCV) on peripheral blood immune cell phenotype and soluble immune-related proteins in blood, while controlling for genetic polymorphisms known to impact HCV-related immune responses, and to determine the impact of the therapy on the emergence of drug-resistant HCV. The study design is informed by the researchers recent investigations of patients receiving HCV treatment. About 4% of patients who had not undergone liver transplantation experienced hepatic decompensating or another serious event. There were several cases of bacterial infection and two cases with elevated markers of autoimmune processes. These events suggest that treatment altered immune responses. About 25% of patients who had undergone liver transplantation experienced hepatic decompensating or another serious adverse event. The long term goal is to understand the pathophysiology of these complications and determine whether HCV treatment can cause an immune reconstitution syndrome in susceptible patients, while improving antimicrobial defenses in others
This study will examine the influence of ribavirin on the initial virological response in treatment-naïve participants with chronic hepatitis C, genotype 1. Participants will be randomized to 1 of 3 treatment groups to receive placebo, ribavirin monotherapy 1000 milligrams (mg) to 1200 mg orally daily depending on body weight or pegylated interferon (PEG-IFN) alfa-2a (Pegasys) 180 micrograms (mcg) subcutaneously (SC) weekly, for 6 weeks. Following the initial 6 weeks, all participants will receive combination therapy with PEG-IFN alfa-2a plus ribavirin (Copegus) for 12 weeks. If there is an initial virological response after 12 weeks of combination therapy, treatment may be continued for a further 36 weeks outside of the study.
Phase 2 study designed to assess the safety, efficacy, and pharmacokinetics of Faldaprevir and TD-6450 alone or in combination with other antivirals for a 12-week treatment duration in treatment-naïve participants with genotype 1b hepatitis C virus (HCV) infection.
The scavenger receptor type B class I (SR-BI) is a receptor for high-density lipoproteins (HDL) and one of entry factors for hepatitis C virus (HCV). The investigators aimed to examine the association of single nucleotide polymorphisms (SNPs) of the SCARB1 gene, which encodes SR-BI, with virologic responses to pegylated interferon-based treatment in Asian chronic hepatitis C (CHC) patients.
Effective all-oral medications are finally available to cure hepatitis C virus, which affects more than 4 million Americans and one-in-four people living with HIV. However, many barriers exist that prevent people with HIV/HCV co-infection from getting this curative treatment, including low knowledge, competing demands, and drug interactions with HIV medications. This study evaluates if a hepatitis C nurse case management intervention in an HIV primary care clinic will improve patient attendance to hepatitis C care and help people start hepatitis C treatment earlier. Half of the participants will receive brief case management with a nurse, while the other half will receive usual clinic care.
The purpose of this phase 3, multicenter study is to evaluate the efficacy and safety of ABT-493/ABT-530 in Japanese adults with chronic Hepatitis C Virus (HCV)-infected, HCV direct-acting antiviral agent (DAA) treatment-naïve, and DAA treatment-experienced Japanese adult subjects.
Hepatitis C Virus, (HCV), infection is a major health concern in the UK with up to 0.7% of the population infected. At best, 25% of those infected will clear the infection spontaneously, though for those who develop a chronic infection, they may go onto to develop liver cirrhosis or liver cancers. The standard of care within the NHS is that patients with a history of intravenous drug use or those currently on methadone are at high risk of having HCV infection and should be offered HCV testing. Once diagnosed they can be referred to nurse led treatment pathways. Less than 10% of the methadone users are even tested for HCV and of them fewer than 20% go onto treatment regimens that successfully clear the infection despite regular interactions with heath care staff. Pharmacists who have daily interactions with patients receiving methadone are ideally placed to deliver anti HCV therapy as they have daily contact with this client group and are well placed to advise on the drug therapy. The SuperDOT C study will examine the impact of pharmacy led Directly Observed Therapy (DOT) for HCV treatment in patients attending Community Pharmacies in participating Health Boards within NHS Scotland. The impact of this approach will be compared with those referred to standard care pathways on how well participants clear their HCV infection.
The investigators will treat 50 patients with cirrhosis due to hepatitis C genotype 1, with sofosbuvir 400 mg daily, ledipasvir 90 mg daily and weight-based ribavirin (1000 mg/d if <75 kg, 1200 mg/d if >75 kg, divided in two daily doses) for 12 weeks and calculate the sustained viral response rate at 12 weeks.
