About this study

Official title: Humoral Immunity Study After a Booster Dose of Soberana Plus (FINLAY-FR-1A) Vaccine Against COVID-19 (Republic of Cuba)

To evaluate the dynamics of IgG levels to the SARS-CoV-2 virus after a booster dose of Soberana Plus vaccine.

Read the detailed description

Prospective clinical study of evaluation of the immune response to booster dose of vaccine against COVID-19 using enzyme immunoassay using the Sunrise Tecan microplate photometer (Austria). The material is participants' plasma, obtained by the standard method. Blood sampling performed 4 times: immediately before the first dose of vaccine, on day 42, 90 days and 180 days after booster dose of vaccine. Booster dose of vaccine against coronavirus infection performing using approved and licensed vaccine Soberana Plus (Republic of Cuba). Venous blood sampling performing standardly. All study participants are informed about the study objectives and upcoming procedures, and all of them given informed written consent to participate the study.

A reagent kit manufactured by Vector-Best (Russian Federation) and designed for enzyme immunoassay for quantitative detection of SARS-CoV-2 class G immunoglobulins, SARS-CoV-2-IgG quantitative ELISA-BEST, D-5505 SARS-CoV-2-IgG (series 5, 6) РУ № РЗН 2022/17065Т used for immunoassay. The "SARS-CoV-2-IgG quantitative ELISA-BEST" reagent kit design uses recombinant full-length trimerized S glycoprotein (Spike) of the SARS-CoV-2 virus derived from a eukaryotic expression system. The protein molecule+ consists of two subunits, S1 containing the RBD domain and S2. The reagent kit "SARS-CoV-2-IgG quantitative ELISA-BEST" detects the pool of immunoglobulin class G synthesized to all antigenic determinants of protein S including the RBD-domain.

The quantification of the SARS-CoV-2 antibody assay is based on the WHO First International Standard (NIBSC code:20/136) and expressed in international units (BAU/ml).

Analytical characteristics of reagent kit "SARS-CoV-2-IgG quantitative ELISA-BEST (series 5, 6)" were: Linearity - within 90-110%, considering the analytical results at wavelengths 405 nm and 415 nm - within the concentration range IgG к SARS-CoV-2 10-5000 BAU/ml; Reproducibility: the coefficient of variation does not exceed 8%). The "opening" test - within 90-110% (samples with absorbances lower than 90% of the cut-off value are considered negative and samples with absorbances higher than 110% of the cut-off value are considered positive. The samples with absorbance in the range of 90-110% of cut-off value are equivocal). Analytical sensitivity - minimal detectable concentration of IgG to SARS-CoV-2 does not exceed 1.0 BAU/ml.

Questions about this trial

What is this clinical trial studying?

A study testing Protein subunit vaccine Soberana Plus (FINLAY-FR-1A) is a vaccine against COVID-19 produced by The Finlay Vaccine Institute and The Centre of Molecular Immunology (Republic of Cuba) in people with Humoral Immunity, run by Gomel State Medical University at 1 site in Belarus.

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 3 inclusion and 3 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 1 Feb 2023. 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 Belarus. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

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?

IgG level assessment (time frame: 42 days after booster dose administration). The study lists 3 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 1 Feb 2023.
