Haven't seen this mentioned on here...more delays incoming...could be what additional docs Therma submitted if they knew this revision was coming down the pipe though...still waiting...and will continue to do so!
On September 23, 2021, the FDA revised the EUAs of certain molecular, antigen, and serology tests to establish additional Conditions of Authorization in response to the continued emergence of new variants of SARS-CoV-2. The revision requires test developers to update their authorized labeling and evaluate the impact of SARS-CoV-2 viral mutations on their test’s performance as outlined in the letter. This revision is effective as of September 23, 2021 for all EUAs that are within the scope of the revision, regardless of whether the revision letter has been added to the test in the table above. Given the large number of affected EUAs, the FDA is working on adding the revision letter to each EUA as quickly as possible. This revision does not apply to EUAs for authorized IL-6 assays or standalone specimen collection devices and does not apply to EUAs that include substantially equivalent viral mutation conditions of authorization.
The FDA has determined that establishing additional conditions is necessary to mitigate the potential risk of false negative results due to either decreased sensitivity or non-reactivity associated with SARS-CoV-2 viral mutations. As set forth in the September 23, 2021 letter, developers of authorized tests that are within the scope of the revision are now required to routinely monitor emerging viral mutations and their potential impact on the performance of the authorized SARS-CoV-2 test(s). If potential impacts are identified, the EUA holder must communicate with the FDA and end users about the potential risk that presence of the mutations may have on test performance. The EUA holder must also update their authorized labeling consistent with the revision letter and submit the labeling to the FDA within 3 months of September 23, 2021. By taking these steps, the FDA and the test developer can quickly act in response to the potential risks identified and, when applicable, share the findings on SARS-CoV-2 Viral Mutations: Impact on COVID-19 Tests.
