Clinical Trial Summary

Randomized, double-blind, placebo controlled, multi-center clinical trials of the tolerability, safety and immunogenicity of the inactivated whole-virion concentrated purified vaccine against COVID-19, manufactured by FSBSI "Chumakov FSC R&D IBP RAS", of childrens aged 12-17" (Clinical trials, phase III). Study purpose is to assess the tolerability, safety and immunogenicity of the inactivated whole-virion concentrated purified coronavirus vaccine of chidrens aged 12-17


Description:

Recruitment of volunteers will be competitive. A maximum of 450 children aged 12 to 17 years inclusive will be screened in the study, of which it is planned to include and randomize 300 children who meet the criteria for inclusion in the study and do not have non-inclusion criteria, data on which will be used for subsequent safety and immunogenicity analysis. Group 1 - 150 volunteers who will be vaccinated with the Nobivac vaccine twice with an interval of 21 days intramuscularly. Group 2 - 150 volunteers who will receive a placebo twice with an interval of 21 days intramuscularly. In case of withdrawal of volunteers from the study, their replacement is not provided.

Reproductive characteristics - For girls with a history of mensis - a negative pregnancy test and consent to adhere to adequate methods of contraception (use of contraceptives within a month after the second vaccination). Girls should use methods of contraception with a reliability of more than 90% (cervical caps with spermicide, diaphragms with spermicide, condoms, intrauterine spirals). - For young men capable of conception - consent to adhere to adequate methods of contraception (use of contraceptives within a month after the second vaccination). Young men and their sexual partners should use methods of contraception with a reliability of more than 90% (cervical caps with spermicide, diaphragms with spermicide, condoms, intrauterine spirals). Research procedures - Written Informed consent of a volunteer (14 years and older) and one of the parents to participate in a clinical trial. - Volunteers who are able to fulfill Protocol requirements (i.e. answer phone calls, fill out a Self-observation Diary, come to control visits). Non-inclusion criteria: - Volunteers cannot be included in the study if any of the following criteria are present: SARS-CoV-2 infection - A case of established COVID-19 disease confirmed by PCR and/or ELISA in the last 6 months. - History of contacts with confirmed or suspected cases of SARS-CoV-2 infection within 14 days prior to vaccination. - Positive IgM or IgG to SARS-CoV-2 detected on Screening. - Positive PCR test for SARS-CoV-2 at Screening / before vaccination. Diseases or medical conditions - Serious post-vaccination reaction (temperature above 40 C, hyperemia or edema more than 8 cm in diameter) or complication (collapse or shock-like condition that developed within 48 hours after vaccination; convulsions, accompanied or not accompanied by a feverish state) to any previous vaccination. - Burdened allergic history (anaphylactic shock, Quincke's edema, polymorphic exudative eczema, serum sickness in the anamnesis, hypersensitivity or allergic reactions to the introduction of any vaccines in the anamnesis, known allergic reactions to vaccine components, etc.). - Guillain-Barre syndrome (acute polyradiculitis) in the anamnesis. - The axillary temperature at the time of vaccination is more than 37.0 ° C. - Positive blood test for HIV, syphilis, hepatitis B/C. - Acute infectious diseases (recovery earl Exclusion Criteria: - • Withdrawal of Informed consent by a volunteer and/or a parent of a volunteer; - The volunteer was included in violation of the inclusion/non-inclusion criteria of the Protocol; - Availability of inclusion/non-inclusion criteria before vaccination; - Any condition of a volunteer that requires, in the reasoned opinion of a medical researcher, the withdrawal of a volunteer from the study; - The established fact of pregnancy before the second vaccination; - Taking unauthorized medications (see section 6.2); - The volunteer's incompetence with the study procedures; - The volunteer refuses to cooperate or is undisciplined (for example, failure to attend a scheduled visit without warning the researcher and/or loss of communication with the volunteer), or dropped out of observation; - For administrative reasons (termination of the study by the Sponsor or regulatory authorities), as well as in case of gross violations of the protocol that may affect the results of the study.
