About this study
Official title: Phase 1 Study of the Safety and Immunogenicity of rDEN2/4delta30(ME), a Live Attenuated Virus Vaccine Candidate for the Prevention of Dengue Serotype 2
Dengue fever, which is caused by dengue viruses, is a major health problem in 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.
Read the detailed description
Dengue viruses cause dengue fever, as well as the more severe dengue hemorrhagic fever/shock syndrome. More than 2 billion people living in tropical and subtropical regions of the world are at risk of dengue virus infection, which is the leading cause of hospitalization and death in children in several tropical Asian countries. This study will evaluate the safety and immunogenicity of a live attenuated dengue virus vaccine called rDEN2/4delta30(ME), which is derived from the DEN2 and DEN4 serotypes.
This study will last 180 days. Participants in Cohort 1 will be randomly assigned to receive rDEN2/4delta30(ME) or placebo at study entry. Cohort 2 will begin only after safety review of all participants in Cohort 1. Participants in Cohort 2 will receive a higher dose of rDEN2/4delta30(ME) or placebo.
After vaccination, participants will be observed for at least 30 minutes for immediate adverse reactions. Participants will also be asked to monitor their temperature every day for 16 days. Study visits will occur every other day after vaccination until Day 16, followed by 4 additional visits at selected days through Day 180. Blood collection and a targeted physical exam will occur at each study visit. Some participants will be asked to undergo a skin biopsy or additional blood collection at selected visits.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing rDEN2/4delta30(ME) Vaccine in people with Dengue Fever, run by National Institute of Allergy and Infectious Diseases (NIAID) 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 3 inclusion and 21 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 21 Jan 2008. 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. Some participants in this study may receive a placebo. 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?
Frequency and severity of vaccine-related adverse effects for each dose graded by severity (time frame: Throughout study). The study lists 2 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 NCT00094705, which also lists 5 linked publications.
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 21 Jan 2008.
