Brief Summary:

The aim of the clinical study is to determine the safety, reactogenicity and immunogenicity parameters of the EpiVacCorona vaccine in volunteers aged 18-60 years.

The research tasks are to:

  • evaluate the safety of the EpiVacCorona vaccine when administered twice intramuscularly;
  • evaluate the reactogenicity of the EpiVacCorona vaccine when administered twice intramuscularly;
  • identify the development of adverse reactions to vaccine administration;
  • study the humoral and cellular immune responses following two doses of the EpiVacCorona vaccine.

Condition or disease Intervention/treatment Phase
Covid19 Biological: EpiVacCorona (EpiVacCorona vaccine based on peptide antigens for the prevention of COVID-19) Other: Placebo (sodium chloride bufus, solvent for the preparation of dosage forms for injection 0.9%) Phase 1 Phase 2

Detailed Description:

The first phase of the clinical trial is an open trial. The study will enroll 14 men and women aged 18 to 30 years, inclusive, who meet the inclusion criteria and have no exclusion criteria, whose data will be used for subsequent analysis of safety and immunogenicity.

The second phase of the clinical trial is a simple, blind, placebo-controlled, randomized, parallel-group study. The study will enroll 86 men and women aged 18 to 60 years, inclusive, who meet the inclusion criteria and have no exclusion criteria whose, the data will be used for subsequent analysis of safety and immunogenicity.

If volunteers drop out of the study, they will not be replaced.

Arms and Interventions

Arm Intervention/treatment
Experimental: "EpiVacCorona" (An Open Study)
Group 1: 14 volunteers who will be vaccinated with the EpiVacCorona vaccine twice spaced 21 days apart, intramuscularly, at a dose of 0.5 ml
 Biological: EpiVacCorona (EpiVacCorona vaccine based on peptide antigens for the prevention of COVID-19)
EpiVacCorona vaccine is intended to prevent COVID-19. The vaccine relies on chemically synthesized peptide antigens of SARS-CoV-2 proteins, conjugated to a carrier protein and adsorbed on an aluminum-containing adjuvant (aluminum hydroxide). The EpiVacCorona vaccine contributes to the development of protective immunity against SARS-CoV-2 coronavirus following two intramuscular administrations spaced 21-28 days apart.
Experimental: "EpiVacCorona" (A Simple, Blind, Randomized Study)
Group 2: Administration of the EpiVacCorona vaccine, intramuscularly, twice, 21 days spaced apart, at a dose of 0.5 ml (43 volunteers)
 Biological: EpiVacCorona (EpiVacCorona vaccine based on peptide antigens for the prevention of COVID-19)
EpiVacCorona vaccine is intended to prevent COVID-19. The vaccine relies on chemically synthesized peptide antigens of SARS-CoV-2 proteins, conjugated to a carrier protein and adsorbed on an aluminum-containing adjuvant (aluminum hydroxide). The EpiVacCorona vaccine contributes to the development of protective immunity against SARS-CoV-2 coronavirus following two intramuscular administrations spaced 21-28 days apart.
Placebo Comparator: "Placebo" (A Simple, Blind, Randomized Study)
Group 3: Тhe use of placebo (sodium chloride, solvent for the preparation of dosage forms for injection 0.9%) intramuscularly twice space 21 days apart at a dose of 0.5 ml (43 volunteers)
 Other: Placebo (sodium chloride bufus, solvent for the preparation of dosage forms for injection 0.9%)
The use of placebo: intramuscularly, twice, spaced 21 days apart, at a dose of 0.5 ml (43 volunteers)
