A Double-blind Randomized Placebo-controlled Study of Safety and Immunogenicity of BVRS-GamVac-Combi

2019-10-21 12:45:29 | BioPortfolio


Two-stage, open-dose, prospective, double-blind, randomized, placebo-controlled study in parallel groups


The study will include volunteers of both sexes, aged 18-55 years inclusive. The study will involve 268 (will receive the vaccine or placebo) healthy volunteers.

At the first stage, it is planned:

- study the safety of component 1 - 40 volunteers and 4 spares *

- study the safety of prime-boost vaccination with component 1 and component 2 with an interval of 21 days in half and full dose - 40 volunteers and 4 spares * At the second phase, it is planned to study the safety and immunogenicity of the vaccine as part of a placebo-controlled randomized trial - 188 people, of whom 138 will receive the vaccine, and 50 will make up the control group of observation - they will be given a placebo. Data from 20 volunteers from the first phase who received the drug in selected dose will be included in the analysis of safety and immunogenicity of the second phase.

- Volunteers are replaced by spares before the introduction of the drug, if the volunteer took the drug, then the replacement is not performed.

Any volunteer who received a dose of the vaccine will be considered as included in the study, the data available on it will be used in assessing the safety and tolerability of the drug.

Persons with no known significant health problems who are recruited to participate in research to test a new drug, device, or intervention as controls for a patient group. (from, accessed 2/14/2013)

Hospital or other institutional ethics committees established to consider the ethical dimensions of patient care. Distinguish from ETHICS COMMITTEES, RESEARCH, which are established to monitor the welfare of patients or healthy volunteers participating in research studies.

Human experimentation that is not intended to benefit the subjects on whom it is performed. Phase I drug studies (CLINICAL TRIALS, PHASE I AS TOPIC) and research involving healthy volunteers are examples of nontherapeutic human experimentation.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
