About this study

Minimal risk research study:

  1. Comparing polyester nasal swabs and foam nasal swabs to detect SARS-CoV-2 virus;
  2. Quantifying the development and trajectory of the disease through clinic visits and blood values.
Read the detailed description

This work will serve both the Everett Clinic and broader UnitedHealth Group patient populations as well as advance the public health emergency response to the community spread of SARS-CoV-2 virus, especially as the number of cases and deaths continues to rise in many geographies. A recent study conducted at The Everett Clinic showed that foam nasal swabs were able to detect SARS-CoV-2 virus at comparable levels to nasopharyngeal (NP) swabs. We now look to build off this work by comparing polyester foam swabs, which are more readily available and mass producible, to foam nasal swabs, in their sensitivity for detecting SARS-CoV-2 virus. We also plan to assess the viability of dry swabbing, where the swab is stored without saline or viral transport media (VTM) at room temperature for four days, to calculate the degradation of the viral sample.

Finally, we will collect up to 50 mL/visit of blood longitudinally from patients who have previously tested positive for SARS-CoV-2 at visit one, two, and four weeks following their initial COVID-10 diagnosis.The medical professional drawing the blood will determine if the patient is at an increased risk from a blood draw due to underlying conditions such as anemia. In these cases, the amount of blood drawn will be left to the discretion of the medical professional but shall not surpass 10 mL per visit.These longitudinal blood samples will help us gain a better understanding of the trajectory of COVID-19 (in terms of both clinical symptomology and viral load) and antibody development. At each visit, nasal swabs and blood samples will be collected, and the blood samples will be stored in a repository for future research.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Odd/Even birth year intervention groupsDiagnostic test

    The nostril used and order of testing will be different in each arm.

Study groups in NCT04327804
Study groupRoleWhat they receive
Odd numbered birth yearThe collection of patient samples will be different as defined by odd/even birth year. Patients born in an odd numbered year will first have their left nostril swabbed by the foam swab followed by their right nostril being swabbed by the two polyester swabs.
Receives: Diagnostic Test: Odd/Even birth year intervention groups
Even numbered birth yearThe collection of patient samples will be different as defined by odd/even birth year. Patients born in an even numbered year will first have their left nostril swabbed by the two polyester swabs followed by their right nostril being swabbed by a foam swab.
Receives: Diagnostic Test: Odd/Even birth year intervention groups

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Detection of SARS-CoV-2 virus

    Measure the agreement between the detection of SARS-CoV-2 virus using a foam nasal swab tested directly after collection, a polyester nasal swab tested directly after testing, and a polyester nasal swab stored at room temperature for four days without saline or VTM before being tested.

    Measured: 42 days

Secondary outcomes (1)
  1. Trajectory of COVID-19 and antibody development

    Longitudinal blood samples from SARS-CoV-2 patients to gain a better understanding of the trajectory of COVID-19 and antibody development

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

An observational study of SARS-CoV Infection, run by UnitedHealth Group 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 8 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 11 Apr 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?

Detection of SARS-CoV-2 virus (time frame: 42 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04327804, which also lists 3 linked publications.

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 11 Apr 2022.
