Active clinical trials for "Hepatitis A"

This multi-center, observational study will examine the clinical use and outcomes of pegylated interferon (PEG-IFN) alfa-2a and ribavirin combination (PEGASYS RBV) in participants with chronic hepatitis C (CHC). Study visits will be scheduled for baseline, 12, 24 and 48 weeks after baseline. An additional follow-up visit at week 72 will be required for participants with an HCV genotype other than 2 or 3. Quality of life data will be collected at baseline, and at each follow-up visit.

Hepatitis C virus (HCV) infection is among the most common of all chronic liver diseases. HCV predominantly affects liver cells and causes the liver to become inflamed and damaged. This can lead to cirrhosis (scarring of the liver), liver cancer or the need for liver transplant. This study will evaluate how effective glecaprevir/pibrentasvir (GLE/PIB) is in participants with chronic HCV infection. Effectiveness will be assessed as the achievement of sustained virologic response. GLE/PIB is an approved drug for the treatment of HCV. Participants 12 years or older with chronic HCV infection will be enrolled. This is a prospective (conducted in future) study in therapy of direct-acting antiviral (DAA) treatment-experienced participants with chronic hepatitis C genotype 1. Around 67 participants will be enrolled at multiple sites in Russian Federation. Participants will receive oral GLE/PIB tablets as prescribed by the physician in accordance with local clinical practice, international guidelines and/or label. Prescription is independent from this study and is decided before providing opportunity to the participate in the study. There is expected to be no additional burden for participants in this trial. All study visits will occur during routine clinical practice and participants will be followed for 12 weeks.

MaHeVi is a multicenter, cross-sectional, population-based study which will include 2500 adults in the health care centers / missions located on the 2 sides of the Maroni River. All major inhabitants of the river border between French Guiana and Suriname may participate, after an extensive communication campaign.The main objective is to estimate the prevalence and status of infection with hepatitis B (HBV), hepatitis C (HCV), D (VHD) and HIV in the general adult population of the Maroni River, border between French Guiana and Suriname. After signing the informed consent and pre-test counseling, capillary blood will be collected on blotting paper. Participants will be interviewed on infection risk factors. Positivity for HBsAg, total anti-HBcAb, anti-HCV Ab, total anti-HDV Ab(for HBsAg positive) and HIV p24 Ag or anti-HIV Ab (confirmed by molecular biology for hepatitis and Western Blot for HIV) will inform respectively on the HBV, HCV, HDV and HIV infection status.

The effective control of nucleos(t)ide analogues for patients infected with hepatitis B has significantly curbed the horizontal transmission of hepatitis B. However, the vertical transmission remains a serious threat to public health for directly increasing the burden of hepatitis B worldwide with the transmission rate up to 80 to 90% among high HBV DNA level if untreated. Currently, the effective prevention of mother-to-child transmission is credited to the implement of HBV vaccination and hepatitis B virus immunoglobin. To leave nobody behind, a growing body of evidence has been yielded to support the use of nucleos(t)ide analogues in the mothers during the late pregnancy. However, the clinical practice can be more complex. Therefore, investigators aim to assess the effectiveness of maternal antiviral therapy and different infants immunoprophylaxis strategy in the prevention of chronic hepatitis infection among children whose mothers were infected with chronic hepatitis B infection in the real world setting.

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.

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.

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.

The purpose of this study is to further evaluate the immunogenicity and safety of 10μg/0.5ml Recombinant Hepatitis B Vaccines(Saccharomyces Cerevisiae) in the Healthy Neonates.
