Adaptive Biotechnologies Announces FDA Emergency Use Authorization for T-Detect™ COVID to Confirm Recent or Prior COVID-19 Infection

First and only clinical T cell-based test for patients to detect the unique T-cell signature specific to SARS-CoV-2, the virus that causes COVID-19

T-Detect COVID correctly confirmed recent or prior COVID-19 infections 97.1% of the time from date of RT-PCR diagnosis with 100% specificity

Adaptive Biotechnologies Corporation, a commercial stage biotechnology company that aims to translate the genetics of the adaptive immune system into clinical products to diagnose and treat disease announced that the U.S. Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA) for T-Detect™ COVID to confirm recent or prior COVID-19 infection. This first-in-class T cell- based test is the first indication resulting from Adaptive’s TCR-Antigen Map collaboration with Microsoft (Nasdaq: MSFT).

“We are proud to receive FDA Emergency Use Authorization for T-Detect COVID, the first indication in an entirely new class of tests that use T cells in the blood to detect disease. People who have been unsure about a prior infection will now have another way to know if they had the virus,” said Chad Robins, chief executive officer of Adaptive Biotechnologies. “The authorization of T-Detect COVID represents a true breakthrough for patients and a pivotal milestone for the diagnostic testing paradigm. We have proven that it is possible to read how T cells detect disease in the blood, and this is just the beginning of a pipeline of tests for many other indications.”

EUA was based on a clinical validation study showing that T-Detect COVID demonstrated sensitivity of 97.1% from date of diagnosis using RT-PCR. Sensitivity is the ability of the test to correctly identify a positive case (true positive). T-Detect COVID also showed a specificity of 100%. Specificity is the ability of the test to identify a negative case (true negative).

“This is the first commercially available T-cell test that confirms recent or prior SARS-CoV-2 infections in people. T-Detect is accurate and what I find especially remarkable is how rapidly it was developed. Going from the lab to real-world human impact in a matter of months demonstrates the true value of our collaboration and the power of merging biology with cloud-scale machine learning technology,” said Peter Lee, corporate vice president, Research & Incubations, Microsoft. “We are hopeful that this technology will have a meaningful impact not only in the global fight against COVID-19, but in many other disease areas in the future.”

The FDA provides an EUA for medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions when there are no adequate, approved, and available alternatives.
