GSK Collaborates with Vir Biotechnology to Find Coronavirus Solutions

GlaxoSmithKline plc (London, UK) and Vir Biotechnology, Inc. (San Francisco, CA, USA) have entered into a collaboration to research and develop solutions for coronaviruses, including SARS-CoV-2, the virus that causes COVID-19. The collaboration will use Vir’s proprietary monoclonal antibody platform technology to accelerate existing and identify new anti-viral antibodies that could be used as therapeutic or preventative options to help address the current COVID-19 pandemic and future outbreaks. The companies will leverage GSK’s expertise in functional genomics and combine their capabilities in CRISPR screening and artificial intelligence to identify anti-coronavirus compounds that target cellular host genes. They will also apply their combined expertise to research SARS-CoV-2 and other coronavirus vaccines. GSK has also entered into a vaccine development agreement with China’s Xiamen Innovax Biotech which is developing a COVID-19 XWG-03 vaccine candidate technology based on a series of truncated S (spike) proteins which will be screened during the pre-clinical testing and a lead candidate will be determined by immunogenicity data. GSK will provide Innovax with its pandemic adjuvant system for preclinical evaluation of the vaccine.

Vir is a clinical-stage immunology company focused on combining immunologic insights with cutting-edge technologies to treat and prevent serious infectious diseases. Vir has assembled four technology platforms that are designed to stimulate and enhance the immune system by exploiting critical observations of natural immune processes. It has a robust method for capitalizing on unusually successful immune responses naturally occurring in people who are protected from, or have recovered from, infectious diseases. The platform is used to identify rare antibodies from survivors that have the potential to treat and prevent rapidly evolving and/or previously untreatable pathogens via direct pathogen neutralization and immune system stimulation. Vir engineers the fully human antibodies that it discovers to enhance their therapeutic potential. This platform has been used to identify and develop antibodies for pathogens including Ebola (mAb114, currently in use in the Democratic Republic of Congo), hepatitis B virus, influenza A, SARS-CoV-2, malaria, and others.

Using CRISPR-based functional genomics, computational biology and machine learning, Vir identifies key host factors necessary for a pathogen’s survival and the protective effects of the innate immune system. Vir then identifies product candidates that may be able to safely target host proteins to block pathogen replication or induce innate immunity to control infection.

Due to the urgent patient need for COVID-19 solutions, the initial focus of the collaboration between GSK and Vir will be to accelerate the development of specific antibody candidates identified by the Vir platform, VIR-7831 and VIR-7832, which have demonstrated high affinity for the SARS-CoV-2 spike protein and are highly potent in neutralizing SARS-CoV-2 in live virus-cellular assays. Subject to regulatory review, the companies plan to proceed directly into a phase 2 clinical trial within the next three to five months. The collaboration will also utilize Vir’s CRISPR screening and machine learning approach to identify cellular targets whose inhibition can prevent viral infection. Additionally, the companies have also agreed to conduct research into SARS-CoV-2 and other coronavirus vaccines by coupling GSK’s vaccines technologies and expertise with Vir’s ability to identify neutralizing epitopes that are present across entire viral families. These efforts will be additive to other initiatives GSK is advancing to develop a potential vaccine for COVID-19.

“Vir’s unique antibody platform has precedented success in identifying and developing antibodies as treatments for multiple pathogens, and it is highly complementary with our R&D approach to focus on the science of immunology. I am very excited that the talent and passion of our two companies will come together to develop solutions for multiple diseases, including the very promising antibody candidates targeting COVID-19,” said Dr. Hal Barron, Chief Scientific Officer and President R&D, GSK.

“It is becoming increasingly clear that multiple therapeutic approaches, used in combination or in sequence, will be necessary to stop this coronavirus pandemic. It is likely that the current coronavirus outbreak will not be the last. These insights are informing our scientific approach and we are pleased to join forces on the execution of this strategy with GSK, who have a like-minded R&D strategy, a deep expertise in vaccines and an impressive global reach to bring medicines to people around the world,” said George Scangos, Ph.D., CEO, Vir Biotechnology.
