NCT ID: NCT06457438 Recruiting - Hepatitis E Clinical Trials

Molecular Characteristics and Prevalence of Viral Hepatitis E in Human Tissue and Cell Donors

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

In this study, the researchers want to focus on the prevalence of anti-HEV antibodies by a new generation test, direct detection of HEV RNA, and its genotypic analysis in a group of human tissue and cell donors.

NCT ID: NCT06306196 Not yet recruiting - Clinical trials for Hepatitis E Virus Infection

Immunogenicity and Safety of Hecolin® in HIV Positive/Negative Adults and in Children

Start date: April 2024
Phase: Phase 2
Study type: Interventional

The primary goal of this clinical trial is to demonstrate non-inferiority of 30 µg of Hecolin® in healthy children, compared to healthy adults as measured by seroresponse rates (SR) of anti-HEV IgG titers, 4 weeks after 3 doses (0, 1 and 6 months) and to assess and descriptively compare safety profile data intra and inter age Strata. As secondary objectives, Geometric Mean Concentration (GMC) of anti-HEV IgG ELISA will be evaluated 4 weeks after 3 doses (0, 1 and 6 months) and 4 weeks after 2 doses (0- and 6-months dose) in healthy children. SR and GMC will also be evaluated 24 weeks after 3 doses and 2 doses. The immune response will be compared among adult participants between HIV positive and HIV negative individuals and between virally suppressed and virally unsuppressed HIV positive individuals

NCT ID: NCT06137313 Recruiting - Hepatitis E Clinical Trials

Exposure to Hepatitis E Virus in Occitania, France

EVE
Start date: December 15, 2023
Phase:
Study type: Observational

The objective of the proposed work is to determine the seroprevalence of HEV in 2023 in a population of blood donors living in Occitania. Compare the current frequency of anti-HEV IgG and IgM markers with that of 2011. The serological techniques used and the questionnaires will be similar

NCT ID: NCT05976594 Recruiting - Hepatitis E Clinical Trials

Long-term Effectiveness of a Recombinant Hepatitis E Vaccine

Start date: August 12, 2023
Phase:
Study type: Observational

This test-negative study is designed to evaluate the long-term effectiveness of hepatitis E vaccine (Hecolin®) and to explore the prevalence of rat hepatitis E in Dongtai City.

NCT ID: NCT05808166 Not yet recruiting - Clinical trials for Hepatitis E Infection

Safety and Immunogenicity of Hecolin® in Healthy Pregnant Women

Start date: June 2024
Phase: Phase 2
Study type: Interventional

This is a phase II randomized, observer-blinded, placebo-controlled study with 3 arms enrolling a total of 2,358 participants. The arms are composed of Arm 1, pregnant participants receiving Hecolin® (N=1,104) with immunogenicity subset (n=150), Arm 2, pregnant participants receiving placebo (N=1,104) with immunogenicity subset (n=150), and Arm 3, non-pregnant participants receiving Hecolin® (N=150) of which all participants in this arm will be included in the immunogenicity subset.

NCT ID: NCT05415345 Active, not recruiting - Clinical trials for Human Papilloma Virus Infection Type 16

Immunogenicity and Safety of Co-immunization With Cecolin and Hecolin

Start date: October 25, 2021
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate the immunogenicity and safety of co-immunization with recombinant human papillomavirus bivalent (Types 16,18) vaccine (Escherichia coli) and Hepatitis E vaccine (Escherichia coli)

NCT ID: NCT05300425 Recruiting - Leptospirosis Clinical Trials

Seroprevalence of Leptospirosis in Val Müstair, Switzerland

Start date: March 3, 2022
Phase:
Study type: Observational

Human leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. Due to its frequent inapparent course or mild severity with unspecific symptoms and limited availability of diagnostic laboratories the incidence of leptospirosis is likely to be underestimated. The hospital of Val Müstair is the major healthcare provider of a rural mountain valley in the canton of Graubünden/ Switzerland with approximately 1500 inhabitants. A relevant prevalence of Leptospira spp. antibodies in the population of the Val Müstair due to its geographic and social risk profile for Leptospira infection, namely the close contact of the population to both livestock and wildlife in agriculture and hunting is estimated. The aim of this study is to analyze the burden of this disease in order to evaluate the need of preventive measures. In addition, seroepidemiological data for the Hepatitis E virus (HEV) and for tularemia will be collected.

NCT ID: NCT04670419 Completed - Hepatitis E Clinical Trials

Morbidity and Mortality of Hepatitis E Virus Infections in Belgium

Start date: January 1, 2010
Phase:
Study type: Observational

Hepatitis E Virus (HEV) infections are emerging in the Western world with a predominance of HEV genotype (gt) 3. Except for age older than 50 years, male gender, chronic liver disease and immunosuppressed status, no correlators with clinical outcomes have been identified so far. With this study, we want to examine viral factors associated with the morbidity and mortality of HEV infections in Belgium as well as find correlators with clinical outcomes.

NCT ID: NCT03827395 Completed - Hepatitis E Clinical Trials

Safety Study of Hepatitis E Vaccine (HEV239)

Start date: April 12, 2019
Phase: Phase 1
Study type: Interventional

This is a Phase I double-blind, randomized, placebo controlled trial (1:4 ratio of placebo to vaccine) of Hepatitis E virus vaccine containing a 239 amino acid subfragment of Hecolin(R) (HEV-239) in 25 US males and non-pregnant females ages 18 - 45 (inclusive) to assess the safety, reactogenicity, and immunogenicity of HEV-239. Subjects will receive 3 doses of study product on Days 1, 29, and 180. Subjects will remain in the study for up to 13 months (including screening). The study duration will be approximately 15 months. Subjects will be observed for 30 minutes after vaccination. The occurrence of solicited injection site and systemic reactogenicity events will be measured from the time of study vaccination through Day 8 after each vaccination. These will be ascertained through use of an electronic memory (e-memory) aid, a telephone call on day 4 after each dose of vaccine, a Day 8 clinic visit, and potentially at the Day 15 clinic visit after each dose of vaccine. Unsolicited adverse events will be collected from vaccination through Day 29 after each vaccination. Serious adverse events will be collected from the time of the first study vaccination through the last study visit (Day 360). The study includes multiple phlebotomy time points for immunogenicity and blood collection for future use at visit 1 and Days 8, 15, and 29 after each vaccination. The durability of the immune response and future use collection will be assessed at 5 months after the first boost (Day 180) and at 6 months after the second boost (Day 360). The primary objectives of the study are to; 1) assess the safety and reactogenicity of HEV-239 following delivery of each vaccine dose; and 2) assess the number of subjects with > / = 4 fold rise in Hepatitis E virus (HEV) immunoglobulin G (IgG) at any time after vaccination.
