Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dengue fever, caused by dengue viruses, is a major health problem in the tropical and subtropical regions of the world. The purpose of this study is to test the safety of and immune response to a new dengue virus vaccine in healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Dengue viruses, which cause dengue fever and dengue shock syndrome, are a major cause of morbidity and mortality in several of the world's tropical and subtropical regions. The rDEN3/4delta30(ME) vaccine is a live attenuated dengue virus vaccine that may be protective against dengue virus serotype 3 (DEN3). The purpose of this study is to evaluate the safety and immunogenicity of the rDEN3/4delta30(ME) vaccine in healthy adults.

This study will last 40 weeks. Participants will be randomly assigned to receive one of three doses of rDEN3/4delta30(ME) or placebo. Participants in Group 1 will receive the middle dose of rDEN3/4delta30(ME) or placebo at study entry. Group 2a will begin enrollment after the immunogenicity review of all participants in Group 1. Participants in Group 2a will receive the highest dose of rDEN4delta30(ME) or placebo at study entry. Group 2b will begin enrollment after the immunogenicity review of all participants in Group 2a. Participants in Group 2b will receive the lowest dose of rDEN4delta30(ME) or placebo.

After vaccination, participants in all groups will be followed closely every other day for the first 16 days of the study. Participants will take their temperature three times a day through Day 16 and record each measurement in a diary. After Day 16, participants will have study visits on Days 21, 28, 42, and 180; a physical exam and blood collection will occur at all visits. Some participants may be asked to join a skin biopsy substudy.
