Randomized, double-blind, multicenter parallel-group clinical study of safety,tolerability and immunogenicity of the Betuvax-CoV-2 vaccine. The aim of this study is toinvestigate the safety, tolerability and immunogenicity of the Betuvax-CoV-2 Recombinantvaccine for the prevention of coronavirus infection caused by the SARS-CoV-2 virus,suspension for intramuscular administration, 10 μg/ml and 40 μg/ml (Ltd. Institute of NewMedical Technologies, Russia) in healthy adult volunteers, aged 18 to 60 (inclusive).
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).
