About this study

Official title: A Phase I, Randomized, Placebo-Controlled, Observer-blind, Two-dose (0-28 Day Schedule) Primary Vaccination Study of WRAIR Tetravalent Dengue Virus Purified Inactivated Vaccine (TDENV-PIV) in Healthy Adults in Puerto Rico

This is a first time in humans (FTiH) study designed to assess the experimental TDENV-PIV vaccine in a predominantly dengue-primed adult population. The study is designed to afford a first time in humans (FTiH) safety and immunogenicity assessment of three TDENV-PIV vaccine candidates, each formulated with a different adjuvant: either aluminum hydroxide, AS01E or AS03B (adjuvants used in GSK Biologicals' hepatitis B candidate vaccine, malaria candidate vaccine and pandemic flu vaccine, respectively). Each vaccine candidate will contain 1 µg of purified virus antigen per each of the four DENV types. Additionally, the study will evaluate an alum adjuvanted TDENV-PIV vaccine candidate containing 4 µg of purified virus antigen per each of the four DENV types. The control group will receive a saline placebo. All experimental vaccinations will be administered according to a 2-dose schedule, 28 days apart. There is a parallel FTiH study that is conducted in the United States in a dengue-naive population using the same investigational vaccines.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and reactogenicity of various TDENV-PIV formulations from Day 0 through 28 days after the second dose (Day 0 - Day 56)

    Safety and Reactogenicity:

    • Occurrence, intensity and relationship to vaccination of solicited local and general adverse events (AEs) during the 7-day follow-up period post each vaccination (Day 0-6)

    Neutralizing antibody titers specific to each DENV type at Day 56

    • Geometric mean titers (GMTs) of neutralizing antibody titers to each DENV type
    • Rate of fold increases in neutralizing antibody from Day 0 for each DENV type
    • Seropositivity rates for each DENV type
    • Trivalent and tetravalent seropositivity rates

    • Occurrence of pIMDs and medically attended AEs from Day 0 to Month 13
    • Occurrence of any SAE from Day 0 to Month 13

    Measured: Up to month 13

  2. Humoral immunogenicity to each of four DENV types of various TDENV-PIV formulations on Days 0, 7 and 28 and Months 7 and 13

    Humoral Immunogenicity:

    • Geometric mean titers (GMTs) of neutralizing antibody titers to each DENV type
    • Rate of fold increases in neutralizing antibody from Day 0 for each DENV type
    • Seropositivity rates for each DENV type

    Measured: Up to month 13

  3. • To evaluate the safety of various TDENV-PIV formulations from Month 14 through the end of the study (Visit 15)

    Occurrence of serious adverse events (SAEs) related to study procedures from Month 14 to end of study (Month 37-39)

    Measured: Up to the end of study (Month 37-39)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Biological/Vaccine: 4 µg TDENV-PIV with Alum adjuvant, Biological/Vaccine: 1 µg TDENV-PIV with AS03B adjuvant and Phosphate buffered saline in people with Dengue Fever, run by U.S. Army Medical Research and Development Command at 1 site in Puerto Rico.

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 10 inclusion and 24 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 23 May 2017. 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 Puerto Rico. 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?

Safety and reactogenicity of various TDENV-PIV formulations from Day 0 through 28 days after the second dose (Day 0 - Day 56) (time frame: Up to Day 56). 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 NCT01702857, 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 23 May 2017.
