Celltrion Receives FDA Emergency Use Authorization for Point of Care Antigen Rapid Test Kit � DiaTrust� COVID-19 Ag Rapid Test

– Available for immediate supply

– Expanded usage scope for use at the Point of Care(POC) and serial testing programs

– Promising test sensitivity for COVID-19 variants with clinical data showing equivalent detection levels for UK variant and Brazil variant

– Clinical trials for Over-the-Counter at-home Testing completed, under FDA review

INCHEON, South Korea–(BUSINESS WIRE)–#AntigenTestKit—Celltrion (KRX:068270) announced on April 29 that DiaTrust� (Celltrion DiaTrust™ COVID-19 Ag Rapid Test) is now launched and available for immediate supply.

DiaTrust™ received the U.S. Food and Drug Administration (FDA) Emergency Use Authorization (EUA) approval for their COVID-19 Point of Care (POC) antigen rapid test kit, DiaTrust™ (Celltrion DiaTrust™ COVID-19 Ag Rapid Test). With the recent EUA approval, DiaTrust^TM is available for immediate supply and distribution.

DiaTrust^TM uses Celltrion’s proprietary antibody, which specifically binds to the COVID-19 virus and detects the infection within 15 minutes. Most rapid test kits in the market generally detect only one of the N or S antigens, but DiaTrust^TM is characterized by maximizing the sensitivity with a dual antigen method that detects both antigens. Clinical trials with patients within the first seven days of symptom onset showed sensitivity and specificity levels at 93.3% and 99.0%, respectively, showing a high level of accuracy.

DiaTrust^TM is also authorized for screening with Serial Testing under an EUA. Serial Testing is intended to be used on individuals without symptoms or other epidemiological reasons to suspect COVID-19 infection. Serial Testing allows the same individual to be tested twice over two (or three) days with at least 24 hours (and no more than 48 hours) between tests, increasing the chances to detect asymptomatic individuals that may not show up with a single test.

Celltrion confirmed the equivalent level of sensitivity of detecting variants from the UK, South Africa, Brazil, California, and New York with clinical studies or in-vitro studies. Clinical trials were conducted in the U.S. when the UK variant was the most prevalent, and clinical trials in Brazil also showed more than 90% sensitivity.

A Celltrion representative stated, “DiaTrust^TM is an antigen test kit that quickly detects the most recent COVID-19 variants from the UK, Brazil, etc., through one test, without the need for expensive detection equipment. As the continued rise of the variants continues to threaten the world, Celltrion plans to expand supplying these testing kits globally.”
