Active clinical trials for "Hepatitis C"

This study measures the prevalence of undiagnosed hepatitis C virus (HCV) infection in HIV-negative men-who-have-sex-with-men (MSM) visiting the sexual health clinics of public health services (in dutch: gemeentelijke gezondheidsdienst, GGD), in order to evaluate if systematic screening for HCV of HIV-negative MSM attending sexual health clinics in the Netherlands is needed.

100 patients with diagnosed HCV were evaluated by clinical and ultrasound examination and were categorized as uncomplicated HCV (n=22) and complicated HCV (n=78). All patients were evaluated for hepatosteatosis and liver fibrosis using the computerized hepatorenal index, the hepatic steatosis index, aspartate aminotransferase (AST)/platelet count index (APRI) and the Fibrosis-4 (FIB-4) scores. Blood samples were obtained for estimation of serum levels of liver function tests and plasma levels of microRNA 21 and 126.

This study observes the effects of newly developed direct-acting antiviral (DAA) treatments on the central nervous system (CNS) of individuals with chronic Hepatitis C (HCV). The goals of this study are to determine the CNS impact of curing chronic HCV disease with newly established DAA therapies and how HIV alters this relationship.

The main objective of this study is to evaluate the safety and effectiveness of paritaprevir/ritonavir/ombitasvir used for patients infected with HCV genotype 1 in daily practice in Japan.

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.

This study seeks to assess the durability of response and persistence of resistance to ombitasvir/ paritaprevir/ritonavir in Japanese participants who enrolled in a Phase 2 or 3 clinical study with these agents for the treatment of chronic hepatitis C.

This protocol is being conducted to comply with the direct request from the Taiwan Food and Drug Administration (TFDA) for a 60-month intensive pharmacovigilance protocol of patients with known hepatitis B (HBV) or hepatitis C (HCV) infection, regardless of control on antiviral therapy in Taiwan and who are treated with ipilimumab for advanced (unresectable, recurrent or metastatic) Melanoma.

Kinshasa, Democratic Republic of Congo (DRC), is where human immunodeficiency virus type 1 (HIV-1) appears to have most diversified. The factors that lead to jumpstarting the HIV-1 epidemic remain unclear; mounting evidence suggests medical interventions may have contributed. Hepatitis C virus (HCV) and human T-cell lymphotropic virus type 1 (HTLV-1) are viruses compatible with long-term survival but with broadly similar modes of transmission as HIV. The main objective was to assess the association of past intravenous treatment with HCV and HTLV-1 seropositivity. The investigators hypothesized that medical interventions in the mid-20th century may have facilitated the emergence of HIV-1 in central Africa. To assess the association of injectable treatments with HCV and HTLV-1 infection and to reconstruct past virus dynamics, the investigators conducted a cross-sectional study of 839 elderly long-term inhabitants of Kinshasa, with serological assays followed by amplification and sequencing. Risk factors were assessed through logistic regression. Phylogenetic methods were used to reconstruct the epidemic history of HCV.

The PROP UP research study is funded by The Patient Centered Outcomes Research Institute (PCORI). PROP UP is a multi-centered prospective observational study that will evaluate all-oral treatment regimens for chronic hepatitis C viral (HCV) infection regarding several patient-reported outcomes (PROs) such as HCV-associated symptoms, treatment side effects, medication adherence, out of pocket costs, comorbid conditions, and long-term benefits of cure and harms of treatment to compare PROs of different treatment regimens, treatment durations, and patient subgroups. Participants will be recruited from 9 U.S. liver centers. Approximately 1920 patients with HCV infection who are prescribed a regimen containing Sofosbuvir/Ledipasvir(SOF/LED), SOF/Velpatasvir(SOF/VEL), Grazoprevir/Elbasvir(GRZ/ELB), OBV/PTV/r + DSV (PRoD), or daclatasvir/SOF (DAC/SOF) will be recruited and approximately 1600 patients who are approved and begin HCV treatment will be enrolled in the longitudinal study. PRO surveys will be evaluated before, during and after HCV treatment. PROP UP is a collaborative effort between behavioral and biomedical researchers, a patient engagement group and a patient advocacy organization.

This study seeks to assess the effectiveness, patient reported outcomes, work productivity and healthcare resource utilization of the interferon-free regimen of paritaprevir /ritonavir (r) - ombitasvir, ± dasabuvir ± ribavirin (RBV) in participants with chronic hepatitis C in a real life setting across clinical practice populations.
