Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participation of the volunteers in the study includes Visit 0 (screening), Visits 1-4 and Visits 10-13 (on an inpatient basis), Visits 5-9 and Visits 14-20 (on an outpatient basis). During Visits 2 and 11, volunteers receive either a study drug (one of two dosages) or a placebo.

The study includes 116 healthy male and female volunteers aged 18 to 60 (inclusive) years who meet the inclusion criteria.

All volunteers are enrolled in two stages of the study and at each stage they are randomized into two or three groups, respectively.

Taking into account the estimated number of volunteers found by the screening results as not meeting the inclusion criteria (54 people), 170 volunteers are screened in the First and Second stage.

The vaccination course includes two intramuscular injections within a 28-day period.

The first stage of the study:

* Group 1 (10 people) will be intramuscularly administered the study drug Betuvax-CoV-2 according to the following scheme: the first injection of 20 μg (0.5 ml of suspension for intramuscular administration of 40 μg/ml), the second injection of 5 μg (0.5 ml of suspension for intramuscular injection of 10 μg/ml) in 28 days.
* Group 2 (10 people) will be intramuscularly administered the study drug Betuvax-CoV-2 according to the following scheme: the first and second injection of 20 μg (0.5 ml of solution for intramuscular injection of 40 μg/ml) within a 28-day period.

The second stage of the study:

* Group 3 (32 people) will be intramuscularly administered the study drug Betuvax-CoV-2 according to the following scheme: the first injection of 20 μg (0.5 ml of the suspension for intramuscular administration of 40 μg/ml), the second injection of 5 μg (0.5 ml of the suspension for intramuscular injection of 10 μg/ml) in 28 days.
* Group 4 (32 people) will be intramuscularly administered the study drug Betuvax-CoV-2 according to the following scheme: the first and second injection of 20 μg (0.5 ml of solution for intramuscular injection of 40 μg/ml) within a 28-day period.
* Group 5 (32 people) will receive a placebo according to the following scheme: the first and second injections (0.5 ml of sodium chloride 0.9% solution, intramuscularly) within a 28-day period.

Study participants will be closely monitored for their intended outcomes. Key safety outcomes will be centrally reviewed by the Independent Data Monitoring Committee (ICMD). Investigators will be required to report anticipated safety outcomes in a timely manner (within 24 hours if possible) and to record these outcomes in the CRF in a timely manner (within 24 hours if possible).
