GenScript Submits Application with FDA for Use of cPass™ SARS-CoV-2 Neutralization Antibody Test in Convalescent Plasma Screening
Novel test detects neutralizing antibodies within an hour
PISCATAWAY, N.J., Jan. 13, 2021 /PRNewswire/ -- GenScript USA Inc., the world's leading research reagent provider, announced today that it has submitted an application to the U.S. Food and Drug Administration's Center for Biologics Evaluation and Research (CBER) for use of the cPass™ SARS-CoV-2 Neutralization Antibody Detection Kit in convalescent plasma screening. The kit, which has been authorized by the FDA for emergency use in clinical diagnostics laboratories, is the first commercially available product to specifically detect COVID-19 neutralizing antibodies without the use of live virus. Neutralizing antibodies block the ability of the virus to infect a cell and are widely recognized biomarkers of immunity.
Convalescent plasma from patients who have recovered from COVID-19 may contain antibodies that fight the virus and is often used as a transfusion treatment for patients hospitalized with COVID-19 to speed recovery. However, successful treatment with convalescent plasma has been variable and new tools are needed to help gauge its effectiveness.
"The cPass is a valuable assay for identifying the functionality and level of antibodies in convalescent plasma prior to its use in treatment," said David Martz, vice president of new product management in the Life Science Group at GenScript. "Convalescent plasma that contains functionally active antibodies that neutralize COVID-19 - rather than binding antibodies that don't block the virus - could be more effective than plasma with low or no neutralizing antibodies. This could potentially increase the effectiveness of convalescent plasma treatment, helping patients to recover more quickly."
The novel cPass test detects neutralizing antibodies in patient samples without the use of live virus. The conventional method of measuring neutralizing antibodies in patient samples requires the use of live cells and a high safety level environment (BSL3). Obtaining results also takes multiple days. In contrast, the cPass™ kit utilizes pure proteins and can be performed in most standard laboratories with a short turnaround time (~1hr).
The cPass kit is also CE marked, and authorized by ANVISA and Health Sciences Authorities in Singapore.
GenScript remains committed to supporting the healthcare community in combatting COVID-19 infections, with a broad portfolio of research and development tools and diagnostics, including the novel cPass kit.
