TDENV PIV and LAV Dengue Prime-boost Strategy Using AS03B Adjuvant
Withdrawn before enrolling · Phase 1 · Has a placebo group
Conditions studied: Dengue
In brief
The potential synergistic effect of administering 2 dengue vaccine candidates that were previously shown to be safe and immunogenic in humans will be evaluated in this study. A prime-boost study of tetravalent dengue virus purified inactivated vaccine (TDENV-PIV) with the GSK AS03B adjuvant and tetravalent dengue live attenuated virus (TDENV-LAV) vaccine Formulation 17 (F17) will gather data to help better understand the human immune response to dengue vaccination and infection. This study is being done to evaluate the safety and immune reaction of administering one dose of dengue purified inactivated vaccine and one dose of dengue live attenuated vaccine compared to two doses of inactivated vaccine.

- Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting 180 days prior to the first vaccine/placebo dose (for corticosteroids, this will mean prednisone 20 mg/day or equivalent; inhaled and topical steroids are allowed)

- Planned administration of any flavivirus vaccine for the entire study duration
- Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or an approved/cleared non-investigational product (pharmaceutical product or device).
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
- Family history of congenital or hereditary immunodeficiency
- History and family history of a bleeding disorder
- History of past flavivirus infection or vaccination (Yellow Fever, tick-borne encephalitis virus (TBEV), Japanese encephalitis virus (JEV), West Nile virus (WNV), dengue (DENV)
- History of, or current, auto-immune disease
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine/placebo or related to a study procedure
- Major congenital defects or serious chronic illness
- History of any neurological disorders or seizures
- Acute disease and/or fever (≥ 100.4° ◦F / 38.0° ◦C, oral body temperature) at the time of enrollment (a subject with a minor illness, i.e., mild diarrhea, mild upper respiratory infection, etc., without fever, may be enrolled at the discretion of the investigator)
- Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic, or renal functional abnormality, as determined by physical examination or laboratory screening tests
- Administration of immunoglobulins and/or any blood products during the period starting 90 days preceding the first dose of study vaccine/placebo or planned administration during the study period
- History of chronic alcohol consumption and/or drug abuse
- A planned move to a location that will prohibit participating in the trial until study end for the participant
- Any other condition which, in the opinion of the investigator, prevents the subject from participating in the study.
