Roche receives FDA CLIA waiver for flu A/B test for use on its cobas Liat PCR System

Basel, 22 September 2015

First CLIA-waived, real-time PCR tests for flu and Strep A now available for physician offices and pharmacies

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 cobas® Influenza A/B test for use on the cobas® Liat System. It is the first CLIA-waived, real-time polymerase chain reaction (PCR) test to detect influenza A and B in ~20 minutes. Coupled with the CLIA waived cobas Strep A test, the cobas Influenza A/B test can now be used by healthcare providers in non-traditional testing sites, including physician offices, emergency rooms, health department clinics, pharmacy clinics and other healthcare facilities.

“Today’s CLIA waiver for the cobas Influenza A/B test allows real-time PCR technology, the gold standard in molecular testing, to be utilized at the point of care to accurately and quickly detect and differentiate influenza A and B,” said Roland Diggelmann, COO, Roche Diagnostics. “Effective management of influenza relies on accurate detection within 48 hours of onset, which can be challenging with current turnaround times for lab-based test results. The cobas Influenza A/B test provides lab-quality PCR results in ~20 minutes, enabling health care providers in all settings to give prompt and confident diagnosis and treatment to patients.”

An estimated three to five million individuals develop influenza each year worldwide, and 250,000 to 500,000 die from the virus.1 Patients at highest risk include children, the elderly and pregnant women. The CLIA waived cobas Influenza A/B test for the cobas Liat PCR System offers an effective, new diagnostic tool to clinicians for the upcoming flu season and provides faster diagnosis and treatment for patients in primary and urgent care settings.

The cobas Influenza A/B test is the second assay on the cobas Liat System to receive CLIA waiver, following the cobas Strep A test, which received CLIA waiver in May 2015. The cobas Liat Analyzer, cobas Influenza A/B test and cobas Strep A test are CE Marked, FDA cleared and CLIA waived.

About the cobas Influenza A/B test

The cobas Influenza A/B test uses real-time PCR technology to detect and differentiate influenza A virus and influenza B virus RNA in ~20 minutes. It targets highly conserved regions of the influenza A and B genomes to provide broad strain coverage of over 30 commonly found strains of influenza A and B.

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. In addition to the existing tests for flu A/B and Strep A, assays for other infectious diseases are in development.

About real-time PCR

Real-time PCR is widely recognized as the gold standard for molecular testing. It is highly accurate and offers a low limit of detection (LOD) to detect viruses in patients with low viral load, such as some adults with influenza infection. PCR is also extremely versatile, offering capabilities with high multiplex testing (e.g. influenza A, influenza B and RSV in the same test), quantification (viral load count), and detection. Additionally, compared to physician clinical management, rapid antigen testing and other point-of-care testing methods, real-time PCR has demonstrated improved detection of influenza.2,3

About influenza A and B (flu)

Influenza is an acute respiratory illness caused by infection with the influenza virus. Influenza viruses consist of three types: influenza A, influenza B and influenza C. In the U.S., influenza A/H1N1, A/H3N2 and influenza B are the predominant seasonal viruses. Influenza A and B viruses are among the leading causes of respiratory infections, estimated to affect 5-10% of adults and 20-30% of children every year worldwide. Influenza is primarily spread by breathing in infected droplets formed when a person with the flu sneezes, coughs, or talks. Symptoms include fever, cough, headache, fatigue, muscle pain, sore throat, and runny nose. Elderly people, young children, and people with weakened immune systems or chronic medical conditions can be at high risk for serious disease. Each year, approximately 3 to 5 million people develop severe illness and 250,000 to 500,000 people die from the flu.4
