Clinical Trial Summary

This study will target Madison Metropolitan School District (MMSD) school children ages 4-19 and staff who have not had a previous positive COVID-19 test within the past 3 months. It will enroll children and adults for 1-3 days to explore whether serial "at-home" BinaxNOW testing is feasible and non-inferior to "at school" single PCR testing for the evaluation of symptomatic individuals with a negative initial BinaxNOW. It will also explore whether lollipop swabs are more acceptable and perform as well as nasal swabs with polymerase chain reaction (PCR) testing.

Description:

Study Design: This is a quantitative community-based study, conducted in the K-12 setting with school children 4-19 years old, teachers, and staff.

If a participant's initial at-school BinaxNOW test is positive, then they will only complete the lollipop swab for PCR testing. They will NOT do the at-home BinaxNOW test.

If a participant's initial at-school BinaxNOW test is negative, then they will complete both the lollipop swab for PCR testing AND an at-home BinaxNOW test approximately 24 hours later.

If the participant is unwilling or unable to complete the at-home test, they will be presented with a lollipop swab only option.

Aim 1: The investigators will test the hypothesis that serial at-home BinaxNOW testing will be feasible and non-inferior to the single at-school PCR testing program. To do this, the investigators will distribute over-the-counter BinaxNOW antigen tests to volunteer families, and create a protocol to ensure families can perform and report test results accurately to the school.

Two key questions will be addressed:

1. Is 'at-home' BinaxNOW testing feasible for families?

2. Is serial 'at-home' BinaxNOW testing non-inferior to 'at-school' single PCR testing?

Aim 2: The investigators will test the hypothesis that lollipop swabs are more acceptable to individuals and PCR testing is non-inferior to performing PCR on nasal swabs. To test this hypothesis, the investigators will work with MMSD schools to incorporate a lollipop swab for PCR at the time a symptomatic student or staff receives a nasal swab for PCR that is part of the Department of Health Services (DHS) program.

Two key questions will be addressed:

1. Are lollipop swabs more acceptable to individuals when compared to nasal swabs?

2. Will lollipop swabs perform as well as nasal swabs with PCR-based testing?

Hypotheses to be tested:

• Aim 1.1: "At-home" BinaxNOW testing will be feasible for families.

• Aim 1.2: Serial "at-home" BinaxNOW testing is non-inferior to "at school" single PCR testing.

• Aim 2.1: Lollipop swabs are more acceptable to individuals than nasal swabs.

• Aim 2.2: Lollipop swabs will perform as well as nasal swabs with PCR-based testing.

Protocol Amendment 2/4/22 to expand the upper eligible age for children from 14 to 19 years and to recognize the potential supply chain limitations of BinaxNOW tests. If the study team does not have any BinaxNOW tests due to a supply shortage, the BinaxNOW procedures will be dropped and only the lollipop swab will be collected.

Protocol Amendment 5/16/22 extends the study timeline and adds a lollipop swab only option.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Standard Diagnostic Test Outcomes for BinaxNOW at Home Testing as Compared to Nasal Swab PCR	The primary diagnostic outcome measure will be the negative predictive value (NPV). The kappa values for sensitivity, specificity, positive predictive value (PPV) and NPV of the BinaxNOW at Home testing with respect to PCR nasal swab (gold standard) are reported here.	up to 2 days
Primary	Frequency Table of Gold-Standard Nasal Swab PCR vs Lollipop Swab PCR COVID-19 Test Results	Counts of negative and positive Nasal Swab vs. Lollipop Swab PCR COVID-19 tests with kappa statistical value.	up to 2 days
Primary	Standard Diagnostic Test Outcomes for Lollipop Swab PCR Testing as Compared to Nasal Swab PCR	The kappa values for sensitivity, specificity, positive predictive value (PPV) and NPV of the Lollipop Swab PCR with respect to PCR nasal swab (gold standard) are reported here.	up to 2 days
Primary	Number of Successfully Completed At-home Tests	Feasibility of 'at-home' BinaxNOW testing will be determined by number of successfully completed at-home tests. At-home test taking will be monitored by study team remotely (via zoom or similar).	up to 24 hours
Primary	Percent of Participants Who Answer 'Yes' When Asked if Lollipop Swabs Are More Acceptable Than Nasal Swabs	To address the acceptability of lollipop swabs vs nasal swabs, the study team will ask participants a binary question: Are lollipop swabs more acceptable to participants when compared to nasal swabs? Yes/No.	up to 1 day
