Study Details

Study Description

Brief Summary

A multi-center, open, phase 4 clinical trial to assess the long-term immunogenicity and safety of fourth administration of Boryung Cell-Culture Japanese Encephalitis Vaccine inj. and to conduct an exploratory investigation on vaccine interchangeability in Korean children aged 6 years who received primary 3 doses with ENCEVAC® or Japanese Encephalitis Vaccine-GCC® inj.

Condition or Disease Intervention/Treatment Phase
  • Biological: Japanese encephalitis vaccine
Phase 4

Detailed Description

This is a follow-up study of KD287-BR-CT-301 (ClinicalTrials.gov identifier: NCT01150942), a phase 3 study to investigate the efficacy and safety of a cell-culture Japanese encephalitis vaccine (ENCEVAC®) compared with that of a mouse brain-derived Japanese encephalitis vaccine (Japanese Encephalitis vaccine-GCC® inj). Subjects participated in KD287-BR-CT-301 study were to receive 3 doses of Japanese encephalitis vaccine (JEV) assigned by randomization from the age of 12 months and those subjects who completed the 3 doses of JEV are the target population in this study. The purpose of this study is to investigate the long-term immunogenicity and safety of the booster (fourth) dose of JEV, which will be given as Boryung Cell-Culture Japanese Encephalitis Vaccine inj, proven to be same with ENCEVAC® but manufactured by a different manufacturer.

Other Names:
  • Boryung Cell-Culture Japanese Encephalitis Vaccine
  • Outcome Measures

    Primary Outcome Measures

    1. To assess the seroconversion rates before and after the fourth dose of JEV [Day 28 (28 days after booster dose)]]

    Secondary Outcome Measures

    1. To assess the seropositive rates before and after the fourth dose of JEV [Day 28 (28 days after booster dose)]]

    2. To assess the geometric mean titer (GMT) before and after the fourth dose of JEV [Day 28 (28 days after booster dose)]]

    3. To assess the percentage of subjects who develop neutralizing antibody titers [Day 28 (28 days after booster dose)]

    4. To assess the percentage of subjects in their neutralizing anti-body titers [Day 28 (28 days after booster dose)]
