V920 Vaccine
BiologicalVesicular Stomatitis Virus (VSV)-based vaccine 1-mL injection containing 3x10^3, 3x10^4, 3x10^5, 3x10^6, 9x10^6, 2x10^7, or 1x10^8 pfu.
Other names: BPSC-1001
NCT Number: NCT02314923
Ebola virus has infected and killed people, mostly in Africa. In 2014, the Ebola virus has affected several thousand people. There is no approved effective way to treat or prevent Ebola. Researchers are trying to develop a vaccine for it. This is a study of the anti-Ebola vaccine BPSC-1001 to see if it is safe and to see how it affects people's immune system.

Phase 1
Between 1994 and the present, there have been many Ebola viruses (EBOV) outbreaks affecting mostly central Africa. However, the 2014 West African outbreak significantly exceeds all previous outbreaks in geographic range, number of individuals affected and in disruption of typical activities of civil society.
This is a Phase 1 safety and tolerability study to evaluate a novel vaccine to Ebola using a live replicating vesicular stomatitis virus (VSV) replacing the gene encoding the G envelope glycoprotein with the gene encoding the envelope glycoprotein from the Zaire strain of Ebola (VSVΔG-ZEBOV also known as V920 and BPSC-1001).

Time frame: Up to 14 days postvaccination
An AE can be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the study vaccine or protocol-specified procedure is also an adverse event. Injection-site AEs prompted on the Vaccination Report Card (VRC) were erythema, pain, tenderness and swelling. AEs were assessed for severity by the investigator according to a toxicity grading scale based on the FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials. Grade 1=Mild; Grade 2=Moderate; Grade 3=Severe; Grade 4=Potentially life-threatening. The percentage of participants that experienced at least 1 solicited injection-site AE was summarized by grade.
Time frame: Up to 14 days postvaccination
An AE can be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the study vaccine or protocol-specified procedure is also an adverse event. Systemic AEs included subjective and objective fever, shivering/chills, sweats, myalgia, arthralgia, joint swelling, joint tenderness, fatigue, headache, gastrointestinal symptoms (nausea, vomiting, abdominal pain, and diarrhea), mucosal lesion, and skin lesion (including any blisters). AEs were assessed for severity by the investigator as follows: Grade 1=Mild; Grade 2=Moderate; Grade 3=Severe; Grade 4=Potentially life-threatening. The percentage of participants that experienced at least one systemic AE was summarized by grade.
Time frame: Up to 56 days postvaccination
An AE can be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study vaccine or protocol-specified procedure, whether or not considered related to the study vaccine or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the study vaccine or protocol-specified procedure is also an adverse event. Unsolicited vaccine-related AEs were those events not specifically listed as either an injection-site (local) or systemic in the VRC and were reported as at least possibly related to the study vaccine or placebo. The AEs were further assessed for severity by the investigator as follows: Grade 1=Mild; Grade 2=Moderate; Grade 3=Severe; Grade 4=Potentially life-threatening. The percentage of participants that experienced at least one unsolicited vaccine-related AE was summarized by grade..
Time frame: Up to 360 days postvaccination
An adverse event is defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with study vaccine. An SAE is an AE that results in death, is life-threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, or is another important medical event. SAEs were assessed for severity by the investigator as follows: Grade 1=Mild; Grade 2=Moderate; Grade 3=Severe; Grade 4=Potentially life-threatening; 5=Fatal. The percentage of participants that experienced at least 1 SAE was summarized by grade.
Time frame: 28 days postvaccination
Blood was drawn on Day 28 to assess the GMTs of ZEBOV-specific IgG antibodies as determined by Enzyme-linked immunosorbent assay (ELISA).
Time frame: Day 360
The optimum dose for general use prophylaxis with V920 was determined following the review of all immunogenicity and safety data.
Time frame: Days 1, 2, 3, 4, 7, 14 and 28 post-vaccination
Participants had blood, assessed for evidence of V920 via polymerase chain reaction (PCR). Mean copies of RNA was reported for all participants who had reading ≥ the LLOQ (62.5 copies/mL)
Time frame: 7, 14, 28, 56, 84 (Cohort 1 only), 180, and 360 days postvaccination
Blood was drawn on Days 7, 14, 28, 56, 84 (Cohort 1 only), 180, and 360 days to assess the GMTs via ELISA. Seroconversion was defined as a post-vaccination titer ≥ 200 ELISA Units/mL that was also at least a 4-fold increase in titer compared to baseline.
Time frame: 7, 14, 28, 56, 84 (Cohort 1 only), 180, and 360 days postvaccination
Blood was drawn on Days 7, 14, 28, 56, 84 (Cohort 1 only), 180, and 360 days to assess the GMTs of Zaire ebolavirus neutralizing antibodies as determined plaque reduction neutralization titer (reciprocal of the dilution that resulted in a 60% decrease in plaques) (PRNT60).
