TRIAL DESCRIPTION
Public title International Multicenter Study of the Immunogenicity of Medicinal Product GamEvac-Combi Combined Vector-Based Vaccine against Ebola Virus Disease, 0.5 ml+0.5 ml/dose
Official scientific title International Multicenter Study of the Immunogenicity of Medicinal Product GamEvac-Combi ¿ Combined Vector-Based Vaccine against Ebola Virus Disease, 0.5 ml+0.5 ml/dose
Brief summary describing the background and objectives of the trial PURPOSE OF THE STUDY The purpose of this study is to evaluate immunogenicity, epidemiological efficacy and safety of medicinal product GamEvac-Combi ¿ Combined Vector-Based Vaccine against Ebola Virus Disease, 0.5 ml+0.5 ml/dose STUDY OBJECTIVES 1. To evaluate immunogenicity of the product in healthy volunteers by measuring the specific antibody titer: - determination of immunity duration 28, 42 days and 3, 6, 12 months after the vaccination by ELISA method vs. baseline values and placebo; - in virus neutralization reaction on day 42 after the vaccination vs. baseline values and placebo; - assessment of antigen-specific cell-mediated immune response (specific T-cell- mediated response to Ebola virus proteins) on Day 28 after vaccination vs baseline values and placebo. 2. Where possible, to evaluate epidemiological effectiveness of vaccination based on the follow-on morbidity indicators of immunized and non-immunized individuals, manifestations of the epidemiological process in time and space. 3. To assess product safety and tolerability by reviewing its impact on the vital parameters in healthy volunteers (systolic and diastolic blood pressure, heart rate, respiration rate, body temperature) and the occurrence of systemic and local post-vaccination reactions in comparison with placebo.

OUTCOMES
Type of outcome Outcome Timepoint(s) at which outcome measured
Primary Outcome the determination of immunity duration after the vaccination using ELISA method vs. baseline values and placebo 28, 42 days and 3, 6, 12 months after the vaccination
Secondary Outcome the assessment of antigen-specific cell-mediated immune responsevs baseline values and placebo on Day 28 after vaccination
Secondary Outcome Safety Outcome Safety assessment will be based on reporting adverse events during the study. ¿ To prevent development of post-vaccination adverse reactions and complications, the volunteers will undergo a screening process with collection of blood and urine specimens to determine baseline health parameters. In addition, medical examination of volunteers will be carried out.
Secondary Outcome determination of immunity duration in virus neutralization reaction on day 42 after the vaccination vs. baseline values and placebo;
