Clinical Trial Summary

The purpose of this study is to evaluate the safety and immunogenicity of the recombinant live attenuated tetravalent dengue virus vaccine admixture TV005 (TetraVax-DV T005) in healthy adults, adolescents, and children in Dhaka, Bangladesh.


Clinical Trial Description

Dengue viruses (DENV) are the leading arboviral infection globally, with over 2 billion people at risk of infection worldwide. The first dengue fever outbreak in Bangladesh occurred in 2000, and since then, dengue fever has had a continued presence throughout Bangladesh. This study will evaluate the safety and immunogenicity of the recombinant live attenuated tetravalent dengue virus vaccine admixture TV005 (TetraVax-DV T005) in healthy adults, adolescents, and children in Dhaka, Bangladesh.

The study will enroll four cohorts of participants: adults, adolescents, children, and young children. Study researchers will evaluate study data for each cohort before enrolling the subsequent cohort.

Participants will be randomly assigned to receive either TV005 vaccine or placebo at study entry (Day 0). Additional study visits will occur on Days 7, 14, 28, 56, 180, 360, 720, and 1080. Study visits will include blood collection, physical examinations, and clinical assessments. Participants will record and monitor their temperature and symptoms until Day 14. Study staff will contact participants daily until Day 14; after Day 14, study staff will contact participants weekly (and after Day 180, monthly) throughout the study for follow-up health monitoring. ;
