NCT04186000

Brief Summary

This Phase 2 study aims to improve preparedness for future Ebola outbreaks by vaccination of a well-known population at risk, ie, a cohort of health care providers (HCP) (such as primary, emergency, and community health care workers) who may be exposed to Ebola in the event of a future outbreak in the Democratic Republic of the Congo (DRC). This study will enhance the immunogenicity database by investigating the kinetics of the humoral immune response. The study will contribute to the safety database (serious adverse events) for VAC52150 following a heterologous vaccine regimen with Ad26.ZEBOV as first vaccine followed by second dose with MVA-BN-Filo administered 56 days later (Day 57). Additionally, after randomization (1:1), a booster vaccination with Ad26.ZEBOV will be executed at 1 year post first dose or 2 years post first dose.

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The participant must pass the Test of Understanding (TOU).
  • Each participant must sign an informed consent form (ICF) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to participate in the study. In case the participant cannot read or write, the procedures must be explained and informed consent must be witnessed by a trusted literate third party not involved with the conduct of the study.
  • Participant must be a man or woman aged 18 years or older.
  • Participant must be a documented health care provider in DRC.
  • Participant must be healthy in the investigator's clinical judgment and on the basis of vital signs assessed at day 1 screening.
  • Before vaccination, a woman must be either:
  • Of childbearing potential and practicing (or intending to practice) a highly effective method of birth control consistent with local regulations and/or local culture regarding the use of birth control methods for participants in clinical studies, beginning at least 28 days prior to vaccination and during the study up to at least 3 months after the first (or only) vaccination (Ad26.ZEBOV) and 1 month after the MVA-BN-Filo vaccination (if applicable); and then starting again 14 days before the booster vaccination until 3 months after the booster vaccination.
  • OR Not of childbearing potential: postmenopausal (amenorrhea for at least 12 months without alternative medical cause); permanently sterilized (eg, bilateral tubal occlusion \[which includes tubal ligation procedures as consistent with local regulations\], hysterectomy, bilateral salpingectomy, bilateral oophorectomy); OR otherwise be incapable of pregnancy.
  • Woman of childbearing potential must have a negative urine β-human chorionic gonadotropin (β-hCG) pregnancy test immediately prior to each study vaccine administration.
  • Participant must be available and willing to participate for the duration of the study.
  • Participant must be willing and able to comply with the protocol requirements, including the prohibitions and restrictions specified in Section 4.3.
  • Participant must be willing to provide verifiable identification.
  • Participant must have a means to be contacted.

You may not qualify if:

  • Known history of Ebola virus disease.
  • Having received any experimental candidate Ebola vaccine less than 3 months prior to the screening at the first visit.
  • Having received any experimental candidate Ad26-vaccine in the past. Known allergy or history of anaphylaxis or other serious adverse reactions to vaccines or vaccine products (including any of the constituents of the study vaccines \[eg, polysorbate 80, ethylenediaminetetraacetic acid (EDTA) or L-histidine for Ad26.ZEBOV vaccine; and tris (hydroxymethyl)-amino methane (THAM) for MVA BN-Filo vaccine\]), including known allergy to egg, egg products and aminoglycosides.
  • Presence of acute illness (this does not include minor illnesses such as mild diarrhea or mild upper respiratory tract infection) or temperature ≥38.0ºC on Day 1. Participants with such symptoms will be excluded from enrollment at that time, but may be rescheduled for enrollment at a later date if feasible.
  • Pregnant or breastfeeding women, or women planning to become pregnant while enrolled in this study until at least 3 months after the Ad26.ZEBOV vaccination or 1 month after MVA-BN-Filo.
  • Presence of significant conditions or clinically significant findings at screening or vital signs for which, in the opinion of the investigator, participation would not be in the best interest of the participant (eg, compromise the safety or well-being) or that could prevent, limit, or confound the protocol-specified assessments.
  • Major surgery (per the investigator's judgment) within the 4 weeks prior to screening, or planned major surgery during the study (from the start of screening onwards).
  • Post-organ and/or stem cell transplant whether or not with chronic immunosuppressive therapy.
  • Received an investigational drug or investigational vaccines or used an invasive investigational medical device within 3 months prior to screening, or current or planned participation in another clinical study during the study.
  • History of chronic urticaria (recurrent hives).
