ADVP005; Dengue CVD 12000 - Dengue-1-Virus Live Virus Human Challenge (DENV-1-LVHC)

2021年10月27日 更新者:Kirsten Lyke、University of Maryland, Baltimore

A Phase 1, Open-Label Clinical Trial With Dengue-1-Virus Live Virus Human Challenge (DENV-1-LVHC) Assessment of Healthy U.S. Adults Previously Primed With Tetravalent Dengue Virus Purified Inactivated Vaccine (TDEN-PIV) and Boosted With Tetravalent Dengue Virus Live Attenuated Vaccine Formulation (TDEN LAV)

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.

調査の概要

詳細な説明

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. The information will help Investigators develop vaccines to protect people from dengue. Participation is voluntary. The duration of participation will last for 180 days (six months). After participants are exposed to the weakened dengue virus, the Investigators will follow them closely to measure their symptoms. Like the flu, participants might expect to have a headache, rash, body aches, fever and chills or they may experience no symptoms whatsoever. If a participant does develops symptoms, the Investigators will monitor him/her closely in a local hotel or a wing of our hospital to ensure safety and to treat symptoms if they occur. Participants will be compensated for their time.

説明

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 (<1.1 x ULN acceptable), platelet decrease which will be exclusionary at Grade 1 or higher
  • 11. Significant screening physical examination abnormalities at the discretion of the investigator, including a BMI > 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 active clinically significant disease
  • 16. Allergy (hives, shortness of breath, swelling of the lips or throat), or hospitalization related to a previous vaccination, anaphylaxis of unknown etiology, or allergy to specific medications/animals for which antigens may be in the virus preparations to include: Shellfish allergy, Fetal Bovine Serum, L-Glutamine, Neomycin and Streptomycin
  • 17. Recent blood donation within prior 56 days of inoculation or planning to donate blood in the one 1 year following inoculation with dengue virus
  • 18. Receipt of blood products or antibodies within 90 days of inoculation or during the study period
  • 19. Any personal beliefs that bar the administration of blood products, transfusions, or serum albumin
  • 20. Participation in the 4 weeks preceding inoculation, or planned participation during the present trial period, in another clinical trial investigating a vaccine except for participation in the ADVP003 or ADVP004 study, drug, medical device, or medical procedure
  • 21. Planned administration of a licensed or study vaccine not planned in the study protocol during the period starting 30 days prior to the DHIM for a live vaccine or 14 days prior to DHIM for inactivated vaccines and extending until 56 days after study completion
  • 22. Planned or current administration of an HMG-CoA reductase inhibitor (i.e., lovastatin, simvastatin, atorvastatin, etc.)
  • 23. Currently taking methadone or suboxone
