NCT02287480

Brief Summary

The hemorrhagic fever resulting from Ebola infection is frequently fatal; the current Ebola outbreak, still in its ascendant phase, has a mortality rate over 50%. There is no proven therapy or prevention available at this time. The vaccine candidate VSV-ZEBOV (BPSC1001) has shown promising safety and efficacy in preventing Ebola Zaire infections in non-human primates (NHP). Before it can be assessed in large Phase IIb/3 trials in affected areas, safety data from phase 1 first-in-human trials are needed. To accelerate this process, the World Health Organization (WHO) has constituted a consortium of Clinical Research Centers in Switzerland, Germany, and Africa that will use similar protocols to collectively include roughly 250 volunteers, the sample size required to identify a 2-fold difference in anti-ZEBOV IgG antibody titers following immunization with 2 different doses of BPSC1001. The joint primary objectives of this single-center, double-blind, randomized placebo-controlled phase 1 dose-finding study are to assess the safety and tolerability of the VSV-ZEBOV vaccine when administered to healthy volunteers at a lower or higher vaccine dose and to define whether seroresponses differ significantly following immunization with the lower or higher vaccine dose.

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

You may qualify if:

  • Has provided written informed consent before screening
  • Adult male or non-pregnant, non-lactating female, ages 18 to 65 (inclusive) at the time of screening
  • Free of clinically significant health problems, as determined by pertinent medical history and clinical examination at study screening
  • Females of childbearing potential who are willing to use an effective method of contraception, from at least 7 days prior to vaccination through the end of the study period, and a double method from day 0 through day 28
  • Males who are willing to use effective contraception from day 0 through day 28:
  • Be willing to minimize blood and body fluid exposure of others for 7 days after vaccination
  • Use of effective barrier prophylaxis, such as latex condoms, during penetrative sexual intercourse (avoiding the sharing of needles, razors, or toothbrushes, avoiding open-mouth kissing, be willing to refrain from blood donation during the course of the study)

You may not qualify if:

  • Prior receipt of an Ebolavirus or Marburgvirus vaccine, a VSV-vectored vaccine, or any other investigational vaccine likely to impact on interpretation of the trial data

  • Receipt of investigational product up to 30 days prior to enrollment or ongoing participation in another interventional clinical trial
  • Receipt of licensed vaccines within 14 days of planned study immunization (30 days for live vaccines) or ongoing participation in another clinical interventional trial
  • Acute or chronic, clinically significant psychiatric, hematologic, pulmonary, cardiovascular, or hepatic or renal functional abnormality as determined by the Investigator based on medical history, physical exam, and/or laboratory screening test
  • Any baseline laboratory screening tests which is outside of acceptable range as defined in the protocol: ALT, AST, creatinine, hemoglobin, platelet count, total white blood cell count, urine protein, urine occult blood, urine glucose
