Capturing Infectious COVID-19 Asymptomatic Cases in Singapore

August 4, 2021 updated by: Becton, Dickinson and Company
This study is being conducted to assess the performance of the BD Veritor™ Plus System for Rapid Detection of SARS-CoV-2, used in serial testing, in identification of infectious, asymptomatic individuals. This information may be used to inform development of an effective testing strategy by policy makers.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This multi-center, prospective, observational, diagnostic evaluation study is designed to assess the performance of the BD Veritor System in the detection of SARS-CoV-2 in asymptomatic individuals compared to viral culture and a commercially available RT-PCR assay over multiple testing time points. The study will enroll a minimum of 150 asymptomatic, adult participants who test positive for SARS-CoV-2 during community/traveler screening procedures.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Participants will be recruited at study sites from individuals admitted for SARS-CoV-2 isolation. Once enrolled, participants may be transferred to a different care unit, or units, throughout their time in the study depending on their medical needs.

Description

Inclusion Criteria:

  1. Male or female ≥21 years of age at the time of informed consent
  2. Has a positive screening test for SARS-CoV-2 by RT-PCR
  3. Is asymptomatic for COVID-19 on the day of their positive screening test (may have symptoms on the actual day of study enrollment)
  4. Is expected to remain at the study site for the full 6-day study period
  5. Willing and able to complete all study required procedures
  6. Provision of signed and dated informed consent form

Exclusion Criteria:

  1. History of frequent or difficult to control nosebleeds within the 14 days prior to study participation
  2. If, at the discretion of the Investigator, involvement in the study is likely to jeopardize the subject's health or their current or future medical treatment

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Prospective Observational Diagnostic Evaluation
Potential participants will be recruited at study sites where they are admitted/held for COVID-19 isolation. On the first day of isolation (ideally on the day they first test positive for SARS-CoV-2), potential participants will be asked to participate in the study. After consent (Study Day 0), two nasopharyngeal swabs (NP swabs) and one nasal swab will be collected. One NP swab will be tested via viral culture and the other nasal swab will be tested by RT-PCR for SARS-CoV-2. The nasal swab will be tested on the BD Veritor System. Specimen collection and testing will be repeated every 2 days for 6 days (Study Day 2, Day 4, and Day 6) or until the RT-PCR Ct value is >30, whichever comes first. Participants will be monitored for symptoms of COVID-19 throughout the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assess the performance of the BD Veritor System for Rapid Detection of SARS-CoV-2 compared viral culture, over multiple collection time points
Time Frame: 6 days
  • Assay results: Positive percent agreement (PPA)
  • Assay results: Negative percent agreement (NPA)
6 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
