  • A family history of congenital or hereditary immunodeficiency.
  • Chronic administration (defined as more than 14 days) of immune-suppressants or other immune-modifying agents within six months prior to administration of study vaccine. (For corticosteroids, this means prednisone, or equivalent, ≥ 0.5 mg/kg/day; topical or inhalable steroids are allowed.)

About this study

Official title: A Phase 1, Double Blind, Randomized, Placebo-controlled Study to Evaluate the Safety and Immunogenicity of Dengusiil in Healthy Adults

This is a Phase 1 study to assess safety and tolerability of a single subcutaneous dose of Dengusiil in healthy adults of 18 to 45 years of age. In this study, immune response to Dengusiil will also be assessed over a period of 6 months and vaccine viremia will also be assessed over a period of 12 days after administration of vaccine.

Being tested
Dengusiil, Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DengusiilBiological

    Also called Live attenuated tetravalent vaccine containing all four dengue virus serotypes (DENV1, 2, 3 and 4)

    Dengusiil is provided as lyophilized powder to be reconstituted with 0.5 mL sterile water for injection (sWFI).The reconstituted vaccine is injected as a single 0.5 mL subcutaneous (SC) dose.

  • PlaceboBiological

    Also called Lyophilized powder containing all the components of the vaccine except DENV serotypes 1, 2, 3 and 4

    Placebo is supplied as a vial of lyophilized powder containing all the components of the vaccine except dengue virus serotypes (DENV1, 2, 3 and 4) to be reconstituted with 0.5 mL sterile water for injection (sWFI).The reconstituted product is injected as a single 0.5 mL subcutaneous (SC) dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dengusiil in people with Prevention of Dengue Fever, run by Serum Institute of India Pvt. Ltd. at 1 site in Australia.

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 13 inclusion and 15 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 3 Jan 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 Australia. 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?

Solicited local and systemic reactions (time frame: 21 days). 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 NCT04035278, 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 3 Jan 2024.
