About this study

Official title: A Phase I, Randomized, Placebo-Controlled, Observer-blind, Two-dose (0-28 Day Schedule) Primary Vaccination Study of Walter Reed Army Institute of Research (WRAIR) Tetravalent Dengue Virus Purified Inactivated Vaccine (TDENV-PIV) in Healthy Adults in a Non-Endemic Region

The study is designed to afford a safety and immunogenicity assessment of three Tetravalent Dengue Virus-Purified Inactivated Vaccine(TDENV-PIV) vaccine candidates.

Read the detailed description

The study is designed to afford a safety and immunogenicity assessment of three Tetravalent Dengue Virus-Purified Inactivated Vaccine(TDENV-PIV) vaccine candidates, each formulated with a different adjuvant: either aluminum hydroxide, AS01E or AS03B (adjuvants used in Glaxo Smith Kline (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.

What is being measured

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

  1. Number of Subjects With Adverse Events Within the 28 Day Follow-up

    Number of subjects with adverse events occurring within days 0-28 following vaccination

    Measured: Days 0-28

  2. Incidence of Any Symptoms (Solicited and Unsolicited) Reported During the 7-day Post Vaccination Period. Total Vaccinated Cohort (TVC)

    Overall incidence of any symptoms (solicited and unsolicited) reported during the 7-day (days 0-6) post vaccination period in TVC population

    Measured: Days 0-6 post vaccination

  3. Incidence of General Symptoms (Solicited and Unsolicited) Reported During the 7-day Post Vaccination Period, Total Vaccinated Cohort (TVC)

    Incidence of General Symptoms (Solicited and Unsolicited) Reported during the 7-day Post Vaccination Period for TVC population. General symptoms are described as fatigue, gastrointestinal symptoms, headache, joint pain, muscle aches and increased temperature (oral).

    Measured: Days 0-6 post vaccination

  4. Incidence of Local Symptoms (Solicited and Unsolicited) Reported During the 7-day Post Vaccination Period, Total Vaccinated Cohort (TVC)

    Incidence of Local Symptoms (Solicited and Unsolicited) Reported during the 7-day Post Vaccination Period in TVC population. Local symptoms are described as pain, redness and swelling.

    Measured: Days 0-6 post vaccination

  5. Summary of Subjects With Serious Adverse Events

    Summary of subjects with serious adverse events through out the study

    Measured: days 0-392

Secondary outcomes (3)
  1. Number of Subjects With Laboratory Values Within and Outside the Normal Ranges and With Different Grade of Adverse Event From Screening to Day 56 Visit

    The percentage of subjects with hematological and biochemical laboratory values within and outside the normal ranges and with different grade of AE were tabulated with exact 95% CI at baseline and at each specified timepoint. Safety laboratory assays were performed at a WRAIR-designated Clinical Laboratory Improvement Amendments-certified laboratory. All safety-related clinical laboratory values were reviewed and all abnormal values were assessed by the investigators as clinically significant or not, with respect to safety.

    PRE = Pre-vaccination, Day 0 visit PI(D7) = Post-dose 1, Day 7 visit PI(D28) = Post-dose 1, Day 28 visit PII(D35) = Post-dose 2, Day 35 visit PII(D56) = Post-dose 2, Day 56 visit PII(M4) = Post-dose 2, Month 4 visit PII(M7) = Post-dose 2, Month 7 visit PII(M10) = Post-dose 2, Month 10 visit PII(M13) = Post-dose 2, Month 13 visit

    Measured: day 56 visit

  2. Geometric Mean Titers (GMTs) of Neutralizing Antibody Titers Specific to Each DENV Type - According to Protocol Population (ATP)

    Geometric Mean Titers (GMTs) of Neutralizing antibody titers specific to each DENV type were measured by a quantitative microneutralization assay with a titer giving 50% reduction in viral infection (MN50) at specified time points. MN50 is specific and sensitive for the detection of anti-DENV neutralizing antibodies. The cut-off for seropositivity was 1: 10 for neutralizing antibody titers measured by MN50 assay. MN50 assay was used to determine initial DENV antibody status of subjects for inclusion in the ATP cohort.

    PRE = Pre-vaccination, Day 0 visit PI(D7) = Post-dose 1, Day 7 visit PI(D28) = Post-dose 1, Day 28 visit PII(D56) = Post-dose 2, Day 56 visit PII(M4) = Post-dose 2, Month 4 visit PII(M7) = Post-dose 2, Month 7 visit PII(M10) = Post-dose 2, Month 10 visit PII(M13) = Post-dose 2, Month 13 visit

    Measured: up to month 13

  3. Number of Subject Showing Monovalent, Bivalent, Trivalent and Tetravalent Response for Neutralizing Antibodies - Total Vaccinated Cohort (TVC)

    Number of subjects showing Monovalent, bivalent, trivalent and tetravalent response for neutralizing antibodies by Microneutralization Titer (giving 50% reduction in viral infection (MN50)) in the TVC population.

    PI(D7) = Post-dose 1, Day 7 visit PI(D28) = Post-dose 1, Day 28 visit PII(D56) = Post-dose 2, Day 56 visit PII(M4) = Post-dose 2, Month 4 visit PII(M7) = Post-dose 2, Month 7 visit PII(M10) = Post-dose 2, Month 10 visit PII(M13) = Post-dose 2, Month 13 visit

    Measured: up to month 13

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 4 µg TDENV-PIV with Alum adjuvant, 1 µg TDENV-PIV with AS03B1 adjuvant and Phosphate buffered saline in people with Dengue Fever, run by U.S. Army Medical Research and Development Command 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 9 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 25 Jan 2019. 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?

Yes. Results are posted in the registry (first posted 25 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Subjects With Adverse Events Within the 28 Day Follow-up (time frame: Days 0-28). The study lists 5 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 NCT01666652, 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 25 Jan 2019.
