Clinical Performance Evaluation of the CareSuperb™ COVID-19 Antigen Home Test

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the accuracy of the CareSuperb™ COVID-19 Antigen Home Test (sensitivity and specificity) in a simulated home use environment when compared to the Roche cobas SARS-CoV-2 (EUA200009), Hologic Panther Fusion SARS-CoV-2 (EUA200014), and Roche cobas SARS-CoV-2 Nucleic acid test for use on the cobas Liat System (EUA210388) high sensitivity Emergency Use Authorization (EUA) SARS-CoV-2 RT-PCR assays.

Detailed Description
-----------------
This is an open label, prospective, randomized clinical agreement study to evaluate the sensitivity and specificity of the CareSuperb™ COVID-19 Antigen Home Test when a lay person conducts the test on themselves, or another study participant, as compared to EUA authorized high sensitivity RT-PCR comparator tests. Patients presenting to the study site for COVID-19 testing who have signed the informed consent and assent, if applicable, and who meet the eligibility criteria will be enrolled in the study. Upon enrollment, the subject will be assigned a unique subject identification (ID) number. After obtaining relevant demographic and medical information, testing will ensue. The first sample, collected by the clinical research staff, will be for the standard of care (SOC). Results of the SOC test will be used for subject treatment and management. To mitigate any potential bias which may affect the subject's visual interpretation of the CareSuperb™ test result, the study staff will not provide the SOC test results to the subject until after the results of the CareSuperb™ test are read by the subject. There will be a 15-minute minimum wait period prior to the collection of the second anterior nares swab sample and an additional 15-minute minimum wait period between the second and third sample collection. For Even numbered subjects, the second sample, collected by a study staff member, will be used for the RT-PCR comparator tests. The third sample will be collected and tested by the lay user, using the CareSuperb™ COVID-19 Antigen Home Test. For Odd numbered subjects, the second sample will be collected and tested by the lay user using the CareSuperb™ COVID-19 Antigen Home Test. The third sample will be collected by a study staff member and will be used for the RT-PCR comparator tests. The clinical study staff member will photograph each subject's test cartridge, labeled with their corresponding subject ID number. Additionally, the study staff member will record whether or not they agree with the test result's interpretation by the subject, and if not, why. The RT-PCR sample will be placed in the provided viral transport medium (VTM) vial and stored in a -70°C freezer until ready for shipment to the central lab. The comparator samples for RT-PCR testing will be shipped to the central lab weekly, unless directed otherwise by either the sponsor or the Clinical Research Organization (CRO). Specimens should be shipped on dry ice for next day delivery, avoiding weekend delivery. RT-PCR testing will be performed by the central lab and residual samples will be stored. The central lab will report both the qualitative results for each sample, i.e., positive or negative for COVID-19, and the cycle threshold (Ct) value for all positive samples.
