Duke-NUS and GenScript Announce Notice of Allowance for U.S. Patent Application for SARS-CoV-2 Surrogate Virus Neutralization Test

PISCATAWAY,N.J. and SINGAPORE,June 21,2021 -- GenScript Biotech Corporation ("GenScript",Stock Code: 1548.HK),a world-leading life sciences research and application service and product provider,and Duke-NUS Medical School,a premier,research intensive medical school,announced today that the U.S. Patent and Trade Office has issued a notice of allowance for the patent application for a novel Surrogate Virus Neutralization Technology (sVNT). Neutralizing antibodies have been scientifically shown to play a major role in preventing infection by blocking a virus from infecting cells.

Developed by Professor Linfa Wang and his team from Duke-NUS,the sVNT neutralization antibody detectiontechnology is exclusively licensed to GenScript for commercializationas the cPass™ SARS-CoV-2 Neutralization Antibody Test. Another key enabler in taking the cPass test to market is the Diagnostics Development Hub,a national platform hosted by Singapore's Agency for Science,Technology and Research,which validated the kit with clinical samples,developed the manufacturing protocols and quality control processes,and secured its provisional authorization by the Health Sciences Authority in Singapore. The kit has been granted emergency use authorization by the U.S. Food and Drug Administration,and is the first and only authorized SARS-CoV-2 neutralizingantibody test product in the US.

"It took only 14 months to receive the notice of allowance,which we view as a strong validation of the innovative sVNT detection methodology," said Dr. Li Zhu,executive director and chief strategy officer of GenScript. "GenScript is honored to have been involved in the R&D and commercialization of the cPass kit. As the majority of the world is entering the post-vaccination COVID era,our focus has shifted from nucleic acid testing to neutralizing antibody detection to measure a person's immune system response to virus infection. Supported by our robust manufacturing and sales networks globally,GenScript is expanding access to cPass so that more research institutes and the public across countries and regions may benefit from this innovative technology."

Associate Professor Christopher Laing,Senior Associate Dean for Innovation and Entrepreneurship at Duke-NUS,said,"This is an encouraging development,as the cPasskitis a useful tool in our continuing battle against COVID-19. With its wide-ranging applications from contact tracing to monitoring the effectiveness of vaccine programs,longevity of protective immunity,and suitability of convalescent plasma for therapy,this novel detection system plays an important role in managing the COVID-19 pandemic."

The cPass test is a safer,faster,easier and more consistent alternative to the traditional live virus- or cell-based tests,with comparable specificity and sensitivity. According to clinical data published in Nature Biotechnology,the sVNT serological detection method was able to detect neutralizing antibodies from patients with 99.93% specificity and 95%-100% sensitivity.

The test does not require a biosafety level 3 facility and can test 96 samples within an hour,significantly reducing the time required for virus detection during experiments. The fact that the kitcan be used to assess immunity tomultiple coronaviruses including SARS-CoV-2 and itsvariants makes it one of the most suitable testing toolsfor large-scale vaccine trials.

Duke-NUS has also filed patent applications for the sVNT technology in China,Europe and Brazil. The cPass detection kit is CE marked in Europe,allowing it to be sold freely in any part of theEuropeanEconomic Area. It has received HSA provisional approval in Singapore,ANVISA in Brazil,ANMAT in Argentina,and recently has been approved bythe Ministry of Health and Prevention (MOHAP) in the United Arab Emirates as a medical device. As a result,the kit has built its presence and is widely recognizedin Asian,African,European and American markets.
