Trial summary

This study will measure the levels of nasal mucosal Immunoglobulin A (IgA) and blood serum IgA up to one year after COVID vaccination, as well as examining what factors might affect antibody levels in the nose. This will be done through nasal epithelial lining fluid collection and standard venipuncture. Read more about this study

About this study

Official title: Vaccine Ig Levels in Nasal Mucosa as Measured by Nasal Epithelial Lining Fluid

This study will measure the levels of nasal mucosal Immunoglobulin A (IgA) and blood serum IgA up to one year after COVID vaccination, as well as examining what factors might affect antibody levels in the nose. This will be done through nasal epithelial lining fluid collection and standard venipuncture.

Read the detailed description

Based on data demonstrating that SARS-CoV-2 infections results in virus-specific nasal IgA levels even in patients with mild infections and no/low serum antibody titers, we hypothesize that COVID vaccinations result in robust nasal IgA levels. Since previous data indicate that SARS-CoV2 specific IgA were transiently present following community-acquired infections, we will follow vaccine-induced nasal IgA levels over time (6-12 months). Our specific aims are as following:

Aim 1: Determine COVID vaccine specific immunoglobulin levels and immune mediator profiles in the nasal mucosa pre- and 14 days post second dose of COVID vaccine.

Aim 2: Determine COVID specific immunoglobulin levels and immune mediator profiles at 3, 6, and 12 months following complete vaccination.

Questions about this trial

What is this clinical trial studying?

An observational study of Vaccine Preventable Disease, run by University of North Carolina, Chapel Hill at 1 site in United States.

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 2 inclusion and 1 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 1 Aug 2022. 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 United States. 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?

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?

Nasal Mucosal COVID-specific IgA (time frame: Up to 14 months). 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 1 Aug 2022.
