Active clinical trials for "Hepatitis C"

This clinical trial studies the effect of sublimated mare milk supplement on patients with hepatitis C.

Elbasvir/grazoprevir (Zepatier®) is a once-daily tablet for the treatment of chronic hepatitis C virus (HCV) GT1a, 1b or 4 infection containing the NS5A inhibitor elbasvir (ELB) 50 mg and the NS3/4A protease inhibitor grazoprevir (GZR) 100 mg. For patients with swallowing difficulties, administration of whole tablets can be problematic. In addition, HCV patients that are hospitalized (at intensive care units) due to severe illness (co-infections/ liver failure) might not be able to swallow medication. Therefore it is useful to know whether it is possible to administer ELB/GZR through a different route, like a feeding tube. In daily practice, information about the safety and efficacy of crushed tablets is lacking which might result in noncompliance, interruption or discontinuation of expensive HCV therapy. However, it is not recommended to interrupt treatment because there is no evidence about the efficacy of the therapy after discontinuation (and restarting). Currently, patients and healthcare professionals are crushing tablets without information about efficacy and safety. Depending on the biopharmaceutical characteristics of a drug formulation, crushing tablets can lead to altered pharmacokinetics of drugs. It is important to know whether pharmacokinetic parameters are influenced by crushing of tablets; both a decrease and an increase in exposure may occur. A decrease of the plasma concentrations of ELB and/or GZR potentially reduces the therapeutic effect of the drugs. Higher doses or switching to other HCV-drugs might be needed. In contrast, in case a higher Cmax and/or AUC occurs there might be an increased risk of toxicity. As a result, crushing the drug is a contra-indication based on the available data. Therefore this study will be conducted to investigate whether a crushed ELB/GZR tablet is bioequivalent to ELB/GZR as a whole tablet.

The purpose of this study was to confirm that combination of narlaprevir (NVR) and ritonavir (RTV) used as a metabolic inhibitor with pegylated interferon (PEG-INF) and ribavirin (RBV) leads to a superior Sustained Virological Response (SVR) rate compared to treatment with pegylated interferon and ribavirin in treatment-naïve and treatment failure patient populations.

To investigate the safety and efficacy of PRI-724 against HCV or HBV liver cirrhosis.

This is an observational cohort study. Participants will be recruited from settings that provide services to people with a risk factor for the acquisition of HCV infection. Participants will attend a single visit to have HCV point-of-care testing. Participants who have not previously received HCV treatment will have a point-of-care HCV antibody test, followed by reflex point-of-care HCV RNA test if positive. Those who have a history of HCV treatment will proceed straight to point-of-care HCV RNA testing. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will receive treatment via standard of care. The purpose of this study is to look at the effect of finger-stick point-of-care hepatitis C testing, to see if it increases the number of tests, diagnoses, and treatments for people with a risk factor of having hepatitis C in Australia.

Patients with hepatitis c showed increased level of oxidative stress. Increased level of serum lipid peroxidation leads to the production of toxic mediators as malondialdehyde (MDA) which lead to disease progression. Chronic stress shunt tryptophan which is essential amino acid toward kynurenic pathway leading to lower level of serotonin and melatonin level. Currently, direct-acting antivirals (DAAs) show well-established efficacy against hepatitis C virus (HCV).

The purpose of this study is to confirm that combination of Narlaprevir, Ritonavir and Daclatasvir is safe and highly effective regimen in treatment-naїve patients with chronic hepatitis C (HCV) genotype 1b infection.

The study aims to assess the effectiveness of a model of hepatitis C screening and integrated care, targeting people who inject drugs (PWIDs) in Hai Phong, Vietnam. In a wider perspective, this model linked to mass screening through repeated Respondent Driven Sampling (RDS) surveys, to simplified treatment protocol, and to large community-based support to improve referral to care, retention in care, adherence to treatment and prevention of reinfection, may have the potential to eliminate HCV among PWIDs in this city.

This study will evaluate the efficacy and safety of glecaprevir/pibrentasvir (ABT-493/ABT-530) in non-cirrhotic chronic hepatitis C virus (HCV) genotype (GT)1 to GT6-infected Asian participants with or without human immunodeficiency virus (HIV) co-infection who are HCV treatment-naïve or treatment-experienced with interferon (IFN) with or without ribavirin (RBV), OR sofosbuvir with RBV with or without IFN.

HCV infection is one of the most prevalent etiologies for liver cirrhosis and hepatocellular carcinoma. HCV is highly heterogeneous, with seven confirmed major genotypes. Each genotype displays a different geographic distribution. Since different HCV genotypes react differently on available antiviral therapies, the correct identification of HCV genotype serves as a marker of responsiveness and an indicator for duration of treatment. The recombinant HCV genotype 2k/1b was first described in Saint Petersburg in 2002. A sequencing strategy led to the detection of HCV genotype 2k/1b. However, clinical laboratories often use the VERSANT HCV Genotype 2.0 Assay for routine HCV genotyping. This assay may potentially misclassify these HCV strains as genotype 2a/2c. Based on these findings, the number of patients with 2k/1b may be underestimated. AbbVie's IFN-free regimen for the treatment of chronic HCV genotype 1b infection includes 3 DAAs with distinct mechanisms of action and non-overlapping resistance pattern to target HCV proteins essential for viral replication. The high efficacy of the 3D regimen was proven in registration clinical trials and RW for 1b population. 3D regimen has not been evaluated for patients with HCV genotype 2K/1B. Primary Objective • Evaluate the efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir (3D) in an interferon-free treatment regimen as assessed by SVR in adult patients with HCV 2k/1b. Study Design: .The study will include 1 group. Patients with HCV GT 2k1b will be treated according to label recommendation as for GT1b (with and without cirrhosis) for 12 weeks. All subjects will receive Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir. Subjects will be assessed for antiviral response, clinical outcomes, patient reported adverse events and presence and emergence of resistance associated variants. Subjects will be followed for up to 12 weeks of treatment and extra 24 weeks of follow up. Scheduled visits will include: physician assessment and blood tests including HCV resistance mutations.
