Phase One, Open Label, Assessment of a Dengue-4-Virus-Live Virus Human Challenge - (DENV-4-LVHC) Virus Strain in Healthy U.S. Adults

University of Maryland, Baltimore·interventional·Posted Mar 7, 2022·Updated Apr 17, 2025

In Brief

A Phase 1 clinical trial evaluating Dengue 4 Live Virus Human Challenge (DENV-4-LVHC) - Low Dose and Dengue 4 Live Virus Human Challenge (DENV-4-LVHC) - Low Dose - Homologous Rechallenge for Dengue. Completed, enrolled 20 participants across 1 site.

Detailed Summary

The purpose of this research study is to test a weakened form of an experimental dengue virus challenge at different doses to test if participants develop symptoms or circulating virus in the blood (called viremia). When volunteers are exposed to dengue on purpose, it is called a "challenge" or Dengue Human Infection Model (DHIM). The research team is collecting information about the safety of the challenge and the best dose to use. The information may help us to make a dengue challenge (a DHIM) that will test vaccines to protect people from dengue.
