Roche Receives FDA CLIA Waiver for the cobas® Liat® PCR System and cobas® Strep A assay

Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the U.S. Food and Drug Administration (FDA) has granted CLIA (Clinical Laboratory Improvement Amendments) waiver for the Roche cobas® Strep A nucleic acid test for use on the Roche cobas® Liat® PCR System. It is the first CLIA-waived PCR test to detect Strep A in throat swab specimens in ~15 minutes. CLIA waiver allows for broad use of the test by healthcare providers in non-traditional laboratory sites, including physician offices, emergency rooms, health department clinics, pharmacy clinics and other healthcare facilities.

“Today’s decision allows the cobas® Strep A test to be utilized in clinical settings that previously relied on rapid antigen technology, which that is less sensitive and often requires confirmatory testing,” said Roland Diggelmann, COO, Roche Diagnostics. “The ~15-minute turnaround time of the cobas® Strep A test offers a much improved experience for both the patient and the healthcare professional when compared to culture testing, which can take several days for a result.”

Strep A causes about 37% of sore throats among children1 and 5-15% in adults2, and it is most common between the ages of 5 and 153. The cobas® Liat® System will provide patients with greater access to prompt diagnosis in a decentralized setting, removing the wait for confirmatory results.

About the cobas® Strep A test

Utilizing polymerase chain reaction (PCR) technology, the cobas® Strep A test can detect Strep A DNA obtained from throat swab specimens in ~15 minutes with the cobas® Liat® System. The cobas® Strep A test is CE-Marked and FDA-cleared.

About the cobas® Liat® System

Utilizing polymerase chain reaction (PCR) technology, the cobas® Liat® System fully automates the testing process, simplifies workflow and enables healthcare professionals to perform molecular testing in a variety of settings with speed, reliability and minimal training. Definitive results are generated in 20 minutes or less to aid a treatment decision. The Analyzer and two initial assays, cobas® Influenza A/B* and cobas® Strep A, are both CE-Marked and FDA-cleared. Roche has also submitted the cobas® Influenza A/B test for CLIA waiver.

*cobas® Influenza A/B is not currently CLIA-waived in the United States and testing sites outside the clinical laboratory.
The cobas® Liat® System is not commercially available in all markets.

About Strep A

Streptococcus pyogenes (Strep A) is a ubiquitous pathogen that causes a wide range of human infections, including pharyngitis, sinusitis, lymphadenitis, pyoderma, endocarditis, meningitis, septicemia, tonsillitis, impetigo, and upper respiratory tract infections. Strep A is capable of initiating two nonsuppurative complications – acute rheumatic fever and post-streptococcal acute glomerulonephritis – which can have severe negative consequences on the health and well-being of infected patients. Accurate diagnosis of acute infection is necessary to properly treat the disease using appropriate antibiotic therapy. If left untreated, Strep A infections can lead to other serious, sometimes life-threatening conditions, including rheumatic fever, scarlet fever, peritonsillar abscess, necrotizing fasciitis, and streptococcal toxic shock syndrome.
