About this study
Official title: A Phase I Dose Comparison Study of the Safety and Immunogenicity of rDEN3delta30/31-7164, a Live Attenuated Virus Vaccine Candidate for the Prevention of Dengue Serotype 3
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
More than 2 billion people living in tropical and subtropical regions of the world are at risk of dengue virus infection. Dengue viruses cause dengue fever, as well as the more severe dengue hemorrhagic fever/shock syndrome, and dengue virus infection 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 called rDEN3delta30/31-7164.
This study will consist of two groups, with Group 1 enrolling first. Group 1 participants will be randomly assigned to receive either 10^3 PFU of rDEN3delta30/31-7164 or placebo subcutaneously in their deltoid. Participants will be monitored at the clinic for 30 minutes after receiving the immunization to monitor for adverse effects. After that, participants will be asked to return to the clinic approximately every other day for the next 16 days, and then on Day 21, 28, 42, and 180. At each visit participants will have physical and clinical exams, vital signs, measures, blood drawn, and will be asked about any adverse events they may have experience. Female participants will be given a pregnancy test. In addition, participants will be asked to measure their temperature 3 times a day and record it in a temperature diary for the first 16 days after immunization.
If less than 90% of the participants in Group 1 seroconvert to DEN3 then Group 2A will be enrolled. Group 2A will follow the same procedures as Group 1, but will receive a 10^5 PFU dose of rDEN3delta30/31-7164.
If more than 90% of the participants in Group 1 seroconvert to DEN3 then Group 2B will be enrolled. Group 2A will follow the same procedures as Group 1, but will receive a 10^1 PFU dose of rDEN3delta30/31-7164.

What is being measured
The primary outcome is the main question the study is designed to answer.
Determine the safety of a single dose of the rDEN3Δ30/31-7164 vaccine, as assessed by the frequency, severity, and seriousness of vaccine related adverse events (AEs).
Measured: Throughout study
Determine the immunogenicity of a single dose of the rDEN3delta30/31-7164 vaccine, as assessed by neutralizing antibody titers to DEN3 at 4 weeks and 6 weeks after vaccination
Measured: Throughout study
Secondary outcomes (7)
Assess the frequency, quantity, and duration of viremia after a single dose of vaccine
Measured: Throughout study
Determine the number of vaccinees infected with rDEN3delta30/31-7164. Infection is defined as recovery of vaccine virus from the blood or serum of a volunteer and/or by seroconversion to DEN3 (a ≥4-fold rise in DEN3 neutralizing antibody titers).
Measured: Throughout study
Compare the infectivity rates, safety, and immunogenicity of a single dose of rDEN3delta30/31-7164 vaccine between the dose level groups.
Measured: Throughout study
Determine the durability of antibody response 26 weeks after vaccination
Measured: At 26 weeks
Obtain an estimate for the Human Infectious Dose-50% (HID50) if dose dependent infectivity is observed
Measured: Throughout study
Evaluate the phenotype of peripheral blood mononuclear cells at primary infection with the rDEN3delta30/31-7164 vaccine.
Measured: Throughout study
Evaluate the cellular and humoral immune response to primary infection with the rDEN3delta30/31-7164 vaccine
Measured: Throughout study

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing rDEN3delta30/31-7164 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 4 inclusion and 20 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 15 Nov 2013. 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?
Determine the safety of a single dose of the rDEN3Δ30/31-7164 vaccine, as assessed by the frequency, severity, and seriousness of vaccine related adverse events (AEs). (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 NCT00831012, which also lists 2 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 15 Nov 2013.
