Expansion of a Dengue-1 Live Virus Human Challenge
April 9, 2024 updated by: State University of New York - Upstate Medical University
Phase One, Open Label Expansion of a Dengue-1-Virus-Live Virus Human Challenge - (DENV-1-LVHC) Virus Strain.
To evaluate the effectiveness of candidate dengue vaccine formulations, it is prudent to develop an appropriate challenge model.
This study supports the expansion of the data set of the current Dengue 1 Live Virus Human Challenge (DENV-1-LVHC) model to produce uncomplicated dengue-like illness.

Detailed Description
This is an expansion of a previous study conducted under NCT02372175.
In this study up to nine healthy subjects between 18 and 45 years old will be inoculated with Dengue 1 Live Virus Human Challenge (DENV-1-LVHC) at a dose used in the previous study.
Subjects will be closely monitored for the first 28 days with continued follow up through 6 months.
Clinical and laboratory parameters, viremia and antibody levels will be assess.
The goal is to expand the data set of symptoms produced by uncomplicated dengue-like illness.
