Trial summary
The Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in 2012 during the first Middle East respiratory syndrome (MERS) outbreak. MERS-CoV causes an acute lower-respiratory infection in humans, with a fatality rate of ~34.5%. Read more about this study

The Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in 2012 during the first Middle East respiratory syndrome (MERS) outbreak. MERS-CoV causes an acute lower-respiratory infection in humans, with a fatality rate of ~34.5%.
The aim of the study is to assess the safety and immunogenicity of adenoviral-based vaccine against MERS - BVRS-GamVac.
Read the detailed description
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 162 (will receive the study drug or placebo) healthy volunteers, of which the first stage, it is planned to vaccinate 40 person with the studied drug (at the same time, the participation of 8 spares *), at the second phase - 122 people, of whom 88 will receive the study drug, and 34 will make up the control group of observation - they will be given a placebo drug.
- Volunteers are replaced by spares before the introduction of the drug, if the volunteer took the drug, then its replacement is not performed.
Any volunteer who received a dose of the test drug 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing BVRS-GamVac in people with MERS (Middle East Respiratory Syndrome) and MERS, run by Gamaleya Research Institute of Epidemiology and Microbiology, Health Ministry of the Russian Federation at 1 site in Russia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 14 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 14 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Inna Dolzhikova, PhD (1933001, info@gamaleya.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Adverse Events (time frame: through the whole study, an average of 180 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2021.
