Coronavirus Infections Clinical Trial

Official title: Double-blind, Placebo-controlled, Randomized Study of Tolerability, Safety and Immunogenicity of the Inactivated Whole-virion Concentrated Purified Coronavirus Vaccine, Produced by FSBSI "Chumakov Federal Scientific Center for Research and Development of Immune-and-Biological Products", on Volunteers at the Age of 18-60 Years

Status Completed

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", on adult volunteers aged 18-60" (Clinical trials, phase I/II). Study purpose is to assess the tolerability, safety and immunogenicity of the inactivated whole-virion concentrated purified coronavirus vaccine sorbed on adult volunteers aged 18-60.

Clinical Trial Description

The study is divided into 3 stages. At Stages I and II of the study, a maximum of 300 healthy volunteers aged 18 to 60 years should be screened, of which 200 volunteers meeting the inclusion criteria and not non-inclusion criteria, should be included and randomized to study the tolerability and safety of the vaccine. Stage I includes 15 men and women: Group 1 - 10 volunteers who will receive the Vaccine twice with an interval of 14 days intramuscularly in a dose of 0.5 ml with a post-vaccination observation period of 28 days. Group 2 - 5 volunteers who will receive placebo twice with an interval of 14 days intramuscularly at a dose of 0.5 ml with a post-vaccination observation period of 28 days. Stage II includes 185 volunteers: Group 1 - 140 volunteers who will receive the Vaccine twice with an interval of 14 days intramuscularly in a dose of 0.5 ml with a post-vaccination observation period of 28 days. Group 2 - 45 volunteers who received placebo twice with an interval of 14 days intramuscularly in a dose of 0.5 ml with a post-vaccination observation period of 28 days. Stage III of the study, a maximum of 300 volunteers should be screened, of which 200 volunteers, meeting the inclusion criteria and not non-inclusion criteria, should be included and randomized to study the safety and immunogenicity of the vaccine. Group 3 - 150 volunteers who will receive the vaccine twice with an interval of 14 days intramuscularly in a dose of 0.5 ml with a period of post-vaccination observation for 6 months. Group 4 - 50 volunteers who will receive placebo twice with an interval of 14 days intramuscularly in a dose of 0.5 ml with a post-vaccination observation period of 6 months. ;
