Clinical Trial Summary

This is a prospective multicenter study conducted to evaluate the performance of the LumiraDx SARS-CoV-2 & Flu A/B tests at point of care sites. Subjects presenting with symptoms suggestive of coronavirus disease 2019 (COVID-19) and Influenza at the time of the study visit will be enrolled and asked to donate swab sample(s) for testing on the device under evaluation.

Description:

This will be a prospective study at point of care sites in the United States for the clinical validation of the LumiraDx SARS-CoV-2 & Flu A/B test for the differential detection of the SARS-CoV-2, and influenza A & B using anterior nasal samples. Up to 1,500 or more symptomatic subjects who are currently experiencing symptoms associated with COVID-19 and Influenza A & B may be enrolled. The samples are obtained from each subject using standard collection methods and are processed and tested by untrained operators without laboratory training and with no prior experience using the candidate test. The primary objective of this study is to evaluate the performance (positive percent agreement, negative percent agreement and 95% confidence intervals for upper and lower bounds) of the LumiraDx SARS-CoV-2 & Flu A/B test for the qualitative and differential detection of SARS-CoV-2, Influenza A & B virus antigen using anterior nares samples collected by a healthcare professional, compared to a 510(k) cleared or Emergency Use Authorized (EUA) high-sensitivity reverse transcription-polymerase chain reaction (RT-PCR) test for COVID-19 and a 510(k) cleared Influenza A/B test. The secondary objective is to assess the usability and user accuracy/performance around limit of detection (LoD) of the investigational test using a questionnaire and accuracy study.

5. Subjects undergoing treatment currently and/or within the past thirty (30) days with prescription medication to treat novel Coronavirus SARS-CoV-2 infection, which may include but is not limited to Remdesivir (Veklury), Paxlovid, molnupiravir or receiving convalescent plasma therapy for SARS-CoV-2.

6. Subjects who have taken Evusheld (tixagevimab/cilgavimab) within the last 90 days.

7. Subjects who have had a nasal wash or aspirate as part of their standard of care treatment on day of study visit prior to study sample collection.

8. Subjects who have had recent craniofacial injury or surgery, including to correct deviation of the nasal septum, within the previous six (6) months.

Intervention

Diagnostic Test:
• LumiraDx SARS-CoV-2 & Flu A/B
The LumiraDx SARS-CoV-2 & Flu A/B test is an automated rapid microfluidic immunofluorescence assay for use with the LumiraDx Platform, for near-patient testing, intended for the qualitative and differential detection of nucleocapsid viral antigens from SARS-CoV-2, influenza A, and influenza B in an anterior nares sample (from both nostrils) collected by a healthcare professional for individuals aged 2 years and older. The test is authorized for individuals with symptoms of COVID-19, influenza A and B within the first 6 days of symptom onset.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Performance evaluation of the LumiraDx SARS-CoV-2 & Flu A/B in point of care settings	Evaluate the performance of the LumiraDx SARS-CoV-2 & Flu A/B test in detecting and differentiating SARS-CoV-2, influenza A and influenza B in fresh nasal swab specimens from symptomatic patients. Performance will be evaluated by use of statistical analysis techniques to assess negative and positive percent agreement (NPA, PPA) of the LumiraDx test results versus an FDA-approved method where a result of 100% NPA or PPA would equate to complete agreement with the reference method and 0% would equate to no agreement.	6 months
Secondary	Validation of the LumiraDx SARS-CoV-2 & Flu A/B for use by intended users	Each site will conduct testing with contrived samples prepared by the Sponsor in a User Accuracy study. Additionally, each operator will complete a usability questionnaire evaluating various features of the investigational test and instructions. Users will use the Likert scale (strongly agree - strongly disagree) to rate their responses. Results will be collated and assessed.	2 months
