Evaluation of Home Use COVID-19 Frequent Antigen Testing and Data Reporting

The protocol will be deployed at three sites in the same geographical location. The design encompasses weekly monitoring of asymptomatic, non- disease populations, confirmed by RT-PCR for presumed positive cases. Each positive case will be followed with daily antigen testing and matched RT-PCR testing for 8 consecutive days in accordance with the CDC's stay-at-home protocol, the positive case will quarantine according to public policy. In addition to asymptomatic participants, participants presenting with a positive The antigen tests that will be utilized are all commercial final products with a CE mark.

All antigen tests utilized are close to identical procedure. Appendix 1 shows the instructions for use of each of the tests. All tests determined nucleoprotein of SARS CoV-2 in a qualitative manner.

Participants are not expected to participate beyond sample collection and processing of rapid antigen test as part of the study. The collection of one anterior nares sample is done once a week. A second nasal swab will be done once a sample indicates presumptive positive for COVID-19. At the end of 4 months of the study we will provide a rate of positive cases over time, and a positive agreement value over 8 days of testing of a positive case. The data will include a Positive Percent Value (PPV) and potentially expand to provide a NPV when negative samples are sent to the CLIA lab to determine the specificity of the tests.

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

1. Individuals 12 year of age or older
2. Provision of paper-consent form and acceptance of participating on a volunteer basis.

Eligible affiliates are individuals who are associated to the member communities of each site and who are identified and consented into the study. These may be individuals who are in close contact with the member community and thus seen as peripheral community members.

• Subjects will be approached by research staff to determine if they would be interested in participating in this study. If willing, a qualified study team member will consent the subject. The electronic system will keep the information about approval of the informed consent by participant. We will also keep a record of the paper and a digital photo of the same document.
• Study staff will provide instructions to participants in the sample collection procedures on site to ensure proper self-sample collection and to minimize the risk of sample contamination. At the time of initial training. The participant will be using a self-swabbing process to obtain the NA sample. If we encounter an impediment for self-swabbing, the process will be done by assisting the participant.
• There will be 3 sites in the same geographical location. The design encompasses weekly monitoring of asymptomatic, non- disease populations by antigen test.The positive case will be followed with daily PCR / antigen test testing for 8 consecutive days in accordance with the CDC's stay-at-home protocol, each quarantine period will be completed. This screening will be used for assessing positive cases and confirming using a CLIA lab authorized molecular test.
• All materials part of the COVID-19 antigen test kit will be provided by the sponsor (Manufacturers provide the test to the sponsors). The test cassettes will be kept at Room Temperature.

SCIENTIFIC RATIONALE FOR STUDY DESIGN

The testing of asymptomatic cases to mitigate COVID-19 Pandemic requires frequent use in the population. Lateral flow bioassays are relatively inexpensive to manufacture, easy to store, and easy for front line use in public setting.

END OF STUDY DEFINITION

Participants are not expected to participate beyond frequent sample collection and processing of rapid antigen test as part of the study. The collection of anterior nares sample will be done once a week, as well as daily testing for up to 8 days in case of positive PCR result.

STUDY ASSESSMENTS AND PROCEDURES

STUDY PROCEDURES

All materials will be provided by the sponsor (IDx20-CCI) along with the co-sponsors owners of the test cassettes. The test cassettes should be kept at Room Temperature until use and in an indoor environment.

1. Subjects will be approached by research staff to determine if they would be interested in participating in this study. If willing, a qualified study team member will conduct a paper or e-informed consent process with the subject. The detailed procedure to conduct the test will be provided (insert) for each type of test each week. In two lenguages. The electronic system will populate the information about approval of the verbal informed consent by participant and it will provide a digital step by step instructions.
2. Study staff will provide support to participants to obtain the instructions and materials for sample collection procedures on site at each of the Chelsea Project sites to ensure proper sample collection and to minimize the risk of sample contamination.
3. The building administrator will have information of a presumptive positive case. Each site will follow their approved procedures for quarantine once the participant has been confirmed by RT-PCR. The participant will be tested at home each day after contracting COVID-19 for the following 8 days. The samples for PCR confirmation will be collected at home and sent to a CLIA lab.

Participant confidentiality and privacy is strictly held in trust by the participating investigators, their staff, and the sponsor(s) and their interventions. This confidentiality is extended to cover testing of biological samples in addition to any clinical information relating to participants. Therefore, the study protocol, documentation, data, and all other information generated will be held in strict confidence. No information concerning the study, or the data will be released to any unauthorized third party without prior written approval of the sponsor.

The study monitor, other authorized representatives of the sponsor, representatives of the Institutional Review Board (IRB), regulatory agencies or pharmaceutical company supplying study product may inspect all documents and records required to be maintained by the investigator, including but not limited to, medical records (office, laboratory facility).

The study participant's contact information will be securely stored at each site for internal use during the study. At the end of the study, all records will continue to be kept in a secure location for as long a period as dictated by the reviewing IRB, Institutional policies, or sponsor requirements.

Study participant research data, which is for purposes of statistical analysis and scientific reporting, will be transmitted to and stored at the The Chelsea Project server. A designed application will be used for the collection of cassette result images. This will not include the participant's contact or identifying information and includes participant ID numbers only. Rather, individual participants and their research data will be identified by a unique study identification number. The study data entry and study management systems used by study sites and by sponsor research staff will be secured and password protected. At the end of the study, all study databases will be de-identified and archived at the sponsor facilities.

FUTURE USE OF STORED SPECIMENS AND DATA

The nasal swab collected in saline will be required for RT-PCR confirmation, these samples will be stored at the CLIA lab (EcoLaboratory. Acton Ma). After the study is completed, the de-identified, archived data will be for use by other researchers as determined by sponsor only.

The data of the study could be used for research purposes.

During the conduct of the study, an individual participant can choose to withdraw consent to have biological specimens stored for future research. However, withdrawal of consent with regard to bio sample storage may not be possible after the study is completed.
