Summary

The purpose of this research study is to test the protection of volunteers previously vaccinated with Tetravalent Dengue Virus (TDEN) Purified Inactivated Vaccine (PIV) with alum and boosted with TDEN live attenuated vaccine (LAV) formulation against a weakened form of an experimental dengue virus challenge. The Investigators will also include people that have not received the study vaccine. The Investigators are collecting information about how the vaccine protects against a dengue virus challenge as well as adding to knowledge about the safety of the challenge.

Eligibility Criteria

Inclusion Criteria

  • 1. Male or non-pregnant, non-breastfeeding female between 18 and 50 years of age (inclusive) at the time of consent.
  • 2. Tetravalent dengue antibody response at 28 days following final vaccination for vaccinated groups of volunteers.
  • 3. Volunteers must be able and willing to provide written informed consent.
  • 4. Volunteers must be healthy as established by medical history and clinical examination at study entry.
  • 5. Volunteers must pass a comprehension test and be able to comply with all study requirements.
  • 6. Female volunteers of non-childbearing potential (non-childbearing potential is defined as having had one of the following: a tubal ligation at least 3 months prior to enrollment, a hysterectomy, an oophorectomy, or is post-menopausal).
  • 7. Female volunteers of childbearing potential may be enrolled in the study, if all of the following apply:
  • Practiced adequate contraception (see Definition of Terms, section 5.4.2.3.) for 30 days prior to challenge
  • Has a negative urine pregnancy test on the day of DHIM
  • Agrees to continue adequate contraception until two months after completion of the DHIM
  • 8. Provide consent for release of medical history records from primary care physician, college or university medical center, urgent care, or emergency room visit

Exclusion Criteria

  • 1. Planned travel during the study period (180 days) which would interfere with the ability to complete all study visits
  • 2. Recent (in the past 4 weeks) travel to any dengue endemic area. These potential volunteers may be eligible for enrollment a minimum of 4 weeks later
  • 3. Volunteer seropositive for hepatitis B surface antigen (HBsAg), hepatitis C virus antibodies (anti-HCV), or human immunodeficiency virus antibodies (anti-HIV)
  • 4. Unvaccinated volunteers positive for antibodies to flaviviruses (FV) to include dengue virus, West Nile virus, Yellow Fever virus, Zika virus, and Japanese encephalitis virus.
  • 5. Any history of FV infection or FV vaccination except for participation in the ADVP003 or ADVP004 dengue vaccination studies; during the study period (Note: Late time point serology from the trials can be tested concomitant to screening serology to clarify if incident FV infection has occurred between vaccination and challenge)
  • 6. Medical history of, or current, diabetes, chronic obstructive pulmonary disease, peptic ulcer disease, coronary artery disease, cardiac arrhythmia, cardiomyopathy, pericarditis, or auto-immune disease
  • 7. Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
  • 8. History of Guillain-Barré syndrome (GBS)
  • 9. History of bipolar disorder, schizophrenia, hospitalization in the past year for a mental health disorder, or any other psychiatric condition, which in the opinion of the investigator prevents the volunteer from participating in the study
  • 10. Safety laboratory test results at screening that are deemed clinically significant or more than Grade 1 deviation from normal with the exception of PT/PTT, fibrinogen decrease, ALT/AST increase ( 35 kg/m2
  • 12. Women who intend to become pregnant or men who intend to father a child during the study period (approximately 6 months)
  • 13. Female: pregnant, lactating or history of heavy menstrual bleeding menstrual periods lasting consistently and regularly longer than 6 days, or consistently and regularly requiring 5 or more pads or tampons per day, and volunteer to the opinion and review of the investigator.
  • 14. Female volunteers using an intrauterine device (IUD) or Mirena®
  • 15. Female volunteers with a history of clinically significant fibroids or uterine polyps, endometriosis, dysmenorrhea, adenomyosis, and uterine scarring (e.g. after D&C), unless treated, with no acti
