or approved and can be used for surveillance purposes only in the United States. Additionally, in the EEA, we affixed a CE Mark (based on a self-assessment of the conformity of the products with the Essential Requirements of Directive 98/79/EC on
diagnostic medical devices) (the “IVDD”)), as permitted prior to the entry into application of the IVDR on May 26, 2022) to our commercially available
antigen test,
antibody test,
antigen pool test,
Ag & Flu A/B tests and our
RNA STAR Complete molecular lab reagent kit and we may submit such tests for regulatory approval, authorization, certification or clearance in other jurisdictions. We have also affixed the CE Mark to new
COVID-19
tests, including our
& RSV test, our five-minute
Ag Ultra and Ultra Pool tests, our Amira System, the Amira
Ag test and two new molecular lab reagent kits which add the ability to test for Flu A/B and two distinct
COVID-19
virus genes to our Fast Lab Solutions product line. Following the United Kingdom’s departure from the European Union, the CE Mark will continue to be recognized in Great Britain (“G.B.”) until June 30, 2023. From July 1, 2023, a U.K. Conformity Assessed (“UKCA”) Mark will be required to place IVDs on the G.B. market (whereas, in Northern Ireland a CE Mark or a CE Mark and UKNI Mark will be required). In addition, in the United Kingdom any COVID-related tests are further subject to coronavirus test device approval (“CTDA”). To date, we have only obtained CTDA approval for our
antigen test, our SARS-CoV-2 Ag & Flu A/B tests and our
RNA STAR Complete molecular lab reagent kit. The volume of tests being developed for
COVID-19
and the speed at which parties are acting to create and test many diagnostic tests for
COVID-19
is unusual and evolving or changing plans or priorities within regulatory authorities, including changes based on new knowledge of
COVID-19
and how the disease affects the human body, may significantly affect the regulatory timeline for our
antigen test,
antigen pool test,
antibody test and our other
COVID-19
related tests. The circumstances surrounding the pandemic may adversely impact the regulatory approval timeline for our Platform and its components both in relation to the
COVID-19
tests, and our other tests generally if regulatory authorities prioritize tests for
COVID-19
over other diseases. Results from clinical testing, the identification of new variants, may raise new questions and require us to proceed with additional reviews or clinical trials, including revising proposed endpoints or adding new clinical trial sites or cohorts of subjects. Additionally, our understanding of
COVID-19,
its infectiveness and other effects on the human body, the ability of individuals to develop antibodies against the virus and the effectiveness of any immune response in preventing future infections are constantly evolving, with new research suggesting sometimes surprising results being published on a frequent basis. New discoveries, new variants or changed understanding of how the virus affects the human body, particularly of its infectivity, impact of various variants and individuals’ immune response to it, could render existing tests, including ours, technologically or commercially obsolete or inferior to new methods that we may or may not be able to develop on a timely basis without significant resources and funding.
Even though we have obtained EUAs for our
antigen test, our
antibody test and our molecular lab reagent kits,
RNA STAR and
RNA STAR Complete, and even if we obtain EUAs for additional tests in the future, an EUA terminates when the emergency determination underlying the EUA terminates. More generally, the FDA has signaled an intention to transition away from providing EUAs for
tests, which could further impact our ability to receive FDA authorization. Moreover, the FDA may revoke an EUA at any time if it determines that the legal criteria for issuing the EUA are no longer met, including if the product may not be effective or the product’s potential benefits for such use do not outweigh its known and potential risks, and we therefore cannot predict how long, if ever, any EUA applicable to our Platform would remain in place. Any revocation or termination of an EUA applicable to our Platform could adversely impact our business in a variety of ways, including if we and our manufacturing collaborators have invested significantly in the supply chain to produce our
COVID-19
tests.
