LumiraDx Announces Intended Use of Its FDA EUA Cleared High Sensitivity COVID-19 Antigen Test Has Been Expanded to Include Testing of Asymptomatic People


LONDON, November 1, 2021 / PRNewswire / – Today, LumiraDx (Nasdaq: LMDX), a next-generation point-of-service diagnostics (POC) company, announced that the intended use of its Emergency Use Authorization (EUA) of the Food and Drug Administration (FDA) authorized the SARS-CoV-2 Antigen Test was expanded to include screening for asymptomatic individuals. This claim builds on its existing claim which covers the use of the test in people suspected of COVID-19 by their health care provider within 12 days of onset of symptoms. The LumiraDx SARS-CoV-2 antigen test initially received EUA from the FDA in August 2020 after demonstrating 97.6% positive agreement and 96.6% negative agreement with RT-PCR in symptomatic patients. Asymptomatic individuals are defined as those without symptoms or other epidemiological reasons to suspect COVID-19.

Nigel lindner, PhD, Chief Innovation Officer of LumiraDx explained, “We understand that one of the most important challenges in keeping infection rates low is being able to quickly and accurately identify SARS-CoV- infection. 2 in asymptomatic individuals. individuals is an essential tool in preventing the transmission of COVID-19. With this clearance from the FDA, we can implement rapid and high sensitivity mass screening programs with our partners in schools, events, workplaces, clinics, travel and other settings and have the test manufacturing capability to support these new nationwide test mandates. ”

The FDA cleared the EUA extension for LumiraDx after reviewing the company’s data on the performance of its SARS-CoV-2 antigen test in individual asymptomatic subjects collected between June 2020 and March 2021. Results indicated high sensitivity and specificity in asymptomatic individuals with the LumiraDx SARS-CoV-2 Ag assay, demonstrating a positive agreement of 82.1% and a negative agreement of 100% with the RT-PCR test in 222 subjects. . These results illustrate the high sensitivity offered by a microfluidic test compared to lateral flow SARS-CoV-2 antigen tests, which independent studies have shown to have sensitivities below 50% in asymptomatic populations.1.2

Study results supporting EUA’s claim for asymptomatic use were recently published in the American Journal of Clinical Pathology.3 Lead author of the article, Dr Paul Drain, Departments of Global Health and Medicine, University of Washington, commented: “The LumiraDx SARS-CoV-2 Antigen test has the advantage of being rapid and sensitive to detect the majority of potentially infected individuals. and helps prevent further transmission.Our study reported a strong agreement between the LumiraDx SARS-CoV-2 Antigen test and the reference RT-PCR test in asymptomatic participants, suggesting that the test is a valuable tool for the rapid screening of symptom-free individuals in community and healthcare settings to limit the spread of COVID-19. He continued, “Rapid results are an important part of virus prevention strategies, allowing the identification and isolation of people who are asymptomatic or pre-symptomatic and who might otherwise unknowingly transmit the COVID-19 virus. This strategy may be important in non- traditional testing environments, such as schools, workplaces, events, and airports. ”

LumiraDx’s high sensitivity SARS-CoV-2 antigen test was developed on the LumiraDx healthcare platform and is currently in use by CVS Pharmacy Inc in the US, the National Health Service (NHS) and Boots in the UK United, a significant number of accidents and emergency Italy and other parts of Europe, hospital systems Japan and through South America, and is deployed in partnership with the Bill & Melinda Gates Foundation in 48 African countries where access to high quality diagnostics is limited.

The LumiraDx SARS-CoV-2 Antigen test is available in the United States and Europe after receiving Emergency Use Authorization (EUA) initially granted by the United States Food and Drug Administration (FDA) in August 2020 and having obtained the CE mark in August 2020.
