About this study
Official title: Phase One, Open Label Assessment of a Dengue-3-Virus-Live Virus Human Challenge - (DENV-3-LVHC) Virus Strain
To evaluate the effectiveness of candidate dengue vaccine formulations, it is prudent to develop an appropriate challenge model. This study will examine the safety and effectiveness of the Dengue 3 Live Virus Human Challenge (DENV-3-LVHC) product and assess the ability of this virus strain to elicit an uncomplicated dengue-like illness.
Read the detailed description
Healthy subjects between 18 and 45 years old will be inoculated with Dengue 3 Live Virus Human Challenge (DENV-3-LVHC) in a dose ranging 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 assessed. The goal is to determine the dose that produces uncomplicated dengue-like illness.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Dengue virus 3 Live Virus Human Challenge (DENV-3-LVHC) in people with Dengue, run by State University of New York - Upstate Medical University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Abnormal Laboratory Measurements (time frame: 28 days post virus inoculation or 7 days post hospitalization, whichever is later). The study lists 17 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04298138, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2024; AzTrials last refreshed its copy on 30 Oct 2026.
