Luminex Corporation announced that it has received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for a new expanded version of its NxTAG® Respiratory Pathogen Panel (RPP) that includes the SARS-CoV-2 virus for high-throughput respiratory testing. The new test is a combination of the company's original NxTAG RPP, an FDA-cleared in vitro diagnostic for syndromic respiratory infection testing, and SARS-CoV-2.

Respiratory infections such as COVID-19 and influenza can be challenging to differentiate and diagnose because they often have overlapping symptoms. NxTAG RPP is a multiplex, high-throughput test designed to enable simultaneous detection of the most common respiratory pathogens for a fast, syndromic testing approach. Following the addition of the SARS-CoV-2 virus target, the panel now includes 19 viral and 2 bacterial targets, combining the most common respiratory pathogens in one panel to help facilitate the rapid identification of various individual and co-occurring infectious pathogens.

NxTAG RPP provides scalable throughput, allowing clinical labs to run up to 96 samples at a time—generating results in approximately four hours with minimal hands-on time. The test runs on Luminex's easy-to-use, compact MAGPIX® System and is designed for use in high-complexity molecular laboratories.

Importantly, the NxTAG RPP + SARS-CoV-2 Assay is expected to detect new variants of the coronavirus. An in silico analysis of molecular probes used in the assay compared to SARS-CoV-2 sequences available in the GISAID database as of February 11, 2021, determined that key sequences still match and should yield a positive result. The analysis included variants originally detected in the United Kingdom (B.1.1.7), South Africa (B.1.351 or 20H/501Y.V2), Brazil (P.1 lineage or 20J/501Y.V3), and California (one of five reoccurring mutations that constitute the B.1.429 lineage and CAL20C).

"Given the emergence of new respiratory pathogens and new variants of these pathogens, it will be increasingly challenging to identify and distinguish the presence and co-existence of SARS-CoV-2, influenza, and other common respiratory pathogens. As a highly accurate, low-cost, multiplex test, our NxTAG RPP + SARS-CoV-2 test delivers an ideal solution for this challenge," said Nachum "Homi" Shamir, Chairman, President and CEO of Luminex. "Clinical laboratories using the assay will be able to scale-up their testing for both COVID-19 and the flu with one high-capacity diagnostic platform that can provide much-needed information for appropriate patient treatment. This is especially important given that the symptoms for the flu, COVID-19, and other respiratory illnesses can be very similar, but their treatment may be very different."

A version of the assay, which also detects Legionella pneumophila and the 2009 H1N1 Flu A subtype, also just received a CE Mark, and was commercialized last month in Europe.

Since the COVID-19 pandemic began, Luminex has expanded capacity for SARS-CoV-2 testing across all of its molecular platforms. The company previously launched the NxTAG CoV Extended Panel under an EUA from the FDA and an Authorization for Import or Sale with Conditions from Health Canada, and also received FDA EUA for its ARIES® SARS-CoV-2 Assay. In August, the company announced it received an EUA from the FDA for its xMAP® SARS-CoV-2 Multi-Antigen Immunoglobulin G (IgG) Assay, a new serology test that can be run on any of Luminex's xMAP-based, high-throughput, gold-standard multiplex platforms. The test detects IgG antibodies, which are an important component of an adaptive immune response and typically reflect sustained immunity to a given pathogen.

The NxTAG CoV Extended Panel and the ARIES® SARS-CoV-2 Assay have each been funded with $642,450 of Federal funds, approximately 36% each of the expected overall cost of development, from the Department of Health and Human Services; Office of the Assistant Secretary for Preparedness and Response; Biomedical Advanced Research and Development Authority, Division of Research Innovation and Ventures under Contract Nos. 75A50120C00037 (NxTAG CoV Extended Panel) and 75A50120C00043 (ARIES® SARS-CoV-2 Assay). Luminex financed the remaining $1,118,663 of each program, constituting 64% each of the total program costs.
