About this study

Official title: A Double-blind Randomized Placebo-controlled Study of Safety and Immunogenicity of Medicinal Product With a Period of Open Safety Assessment in Two Modes of Administration, in Healthy Volunteers

The aim of the present study is at the first stage: a comparative assessment of the safety of the two methods of vaccine administration, at the second - an assessment of the safety and state of post-vaccination immunity at different times after vaccination

Read the detailed description

In the first stage estimate of safety of vaccine after its single administration to the nasal cavity by the drip method or by spray - dispenser during the period of observation in 30 days with the participation of 24 volunteers, divided into 2 groups of 12 people for each method of administration

After interim analysis of safety data is subject to the consent of the local ethics Committee of the Research Centre about the possibility of further studies of the drug - will be started the second phase of the study, which, along with continued security research, provides the definition of the parameters of immunogenicity of the study drug. The second phase of the study will included 200 participants, including 100 people will receive the study drug and 100 will be a control group of observation - that is, will get a placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GamFluVac in people with Healthy Volunteers, 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 20 inclusion and 22 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: finished, as of the sponsor's last update on 25 Aug 2020. 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 phase mean?

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. 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 2 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 25 Aug 2020.
