Active clinical trials for "Encephalitis, Japanese"

The primary objective is to assess the safety profile of IC51 in a pediatric population from regions where JEV is not endemic

The purpose of this study is to observe the occurrence of adverse events and seroconversion rate, geometric mean titres (GMTs) of live attenuated varicella vaccine，live attenuated JE vaccine and live attenuated varicella vaccine combined with live attenuated JE vaccine, respectively.

A study of the study vaccine (JECEVAX- VABIOTECH-Vietnam) and a licensed vaccine (JEVAX-VABIOTECH-Vietnam) is conducted in Vietnamese children, aged 9 to 24 months to assess the safety of the study vaccine compares to licenced vaccine. Two hundred and twenty children are enrolled and randomly assigned into 2 groups (110 children/group), each of which receive 2 doses of study / control vaccine subcutaneously, at 28-34 days interval. Safety data included immediate reaction at the injection site and systemic reaction within 30 min of administration, solicited and unsolicited adverse events occurs from the 1st dose to 28-34 days after first dose and from the second dose to 28-34 days after 2nd dose. SAE (from start of first dose to 28-34 days after second dose).

A dose escalating study with 3 different dosing regimens of the studied vaccine (JECEVAX- VABIOTECH-Vietnam) and a licensed vaccine (JEVAX-VABIOTECH-Vietnam) is conducted in Vietnamese children, aged 9 to 24 months to assess the safety and immunogenicity. Two hundred children are enrolled and randomly assigned into 4 groups (50 children/group), each of which receive 2 doses of study / control vaccine subcutaneously, at 10-12 days interval. Safety issues included immediate reaction at the site of injection and systemic reaction within 30 min of administration, solicited and unsolicited adverse events occurs from the first dose to 30 days after second dose; SAE (from start of first dose to 30 days after second dose), blood cell count, urea, ALT, AST. Immunogenicity outcomes include seroconversion of neutralizing antibodies (blood samples are taken prior to 1st dose and 20-22 days post 2nd dose).

The aim of the study is to investigate the memory immune response and the yearly persistence of the immunity against Japanese Encephalitis (JE) after vaccination with Japanese Encephalitis Chimeric Virus Vaccine (JE-CV) in participants previously vaccinated with JE-CV vaccine. Objectives: To describe JE immune status before and after JE-CV vaccination in subjects previously vaccinated with JE-CV vaccine To describe the immune status before and after JE-CV vaccination in JE-naïve control subjects. To describe the safety (in terms of solicited and unsolicited adverse events) of a single dose of JE-CV vaccine up to 6 months after the last vaccination. To describe all related serious adverse events (SAEs) and related deaths from 6 months to 5 years after vaccination in JE-CV-primed subjects.

This is a randomized, open-label Phase 3 study including children aged >9 months to <17 years and 7 months who have been vaccinated with IXIARO in study IC51-323.

To assess the immunogenicity and safety of the vero cell-derived inactivated JE vaccine in Korean healthy children aged 12~23 months

This study is to assess the safety and immunogenicity of three consecutive lots of JE-CV in toddlers aged 12-18 months. Primary objective: To demonstrate the bio-equivalence of three lots of JE-CV vaccine manufactured by sanofi pasteur. Secondary objective: To describe the safety of vaccination in all subjects

The primary objective is to assess the systemic and local safety profile of purified inactivated Japanese Encephalitis Virus (JEV) vaccine IC51 administered in two doses in a 28 days interval up to Month 7 after the first IC51 vaccination in a pediatric population from endemic regions.

The purpose of this study is to determine non-inferiority in seroconversion and to compare the safety and tolerability between ChimeriVaxTM-JE and JE-VAX to the respective homologous virus strain after completion of vaccination course.
