“If a single antibody can provide an effective therapy from which the virus can’t escape, it has a lot of advantages in terms of cost of goods [and] in terms of the number of patients who can be treated with a given manufacturing capacity,” Scangos said.George Scangos, Vir BiotechnologySign in to your BioCentury account to access your content.Get a two-week free trial subscription to BioCentury We are strongly committed to using our voice and actions to build a new world where bigotry and inequality no longer infect our institutions or our hearts.Our four current technology platforms are designed to, either individually or in combination, stimulate and enhance the immune system by exploiting critical observations of natural immune processes.Vir is focused on combining immunologic insights with cutting-edge technologies to treat and prevent serious infectious diseases.The death of George Floyd is a stark reminder that racism and the consequent discrepancies in health care, education, and opportunities that result are still, after centuries, a serious issue within our society. Vir Biotechnology is investing in cures, treatments, and preventions for challenging viral and bacterial diseases, including those caused by drug-resistant bacteria and emerging pathogens.

People across the country, who see this event as a symbol of institutionalized racism, are expressing their frustration and anger, with the majority demonstrating peacefully. It seeks to take a new approach, using breakthroughs in immune programming to manipulate pathogen-host interactions. Arch managing director Robert Nelson is a Vir co-founder and investor. “We put together several different cocktails and we’ve put them in our queue for large-scale manufacturing.”Vir and Regeneron have similar development timetables.Rather than looking for antibodies against epitopes that are conserved between SARS-CoV-1 and SARS-CoV-2, Regeneron is restricting its search to the latter.SARS-CoV-2 S - SARS-CoV-2 spike proteinScangos said Vir believes the best approach is to find epitopes that have “been conserved over many years of divergent evolution, when most parts of the virus have changed.” These are “likely to be very important for the virus in some functional sense” and therefore are unlikely to change when the virus mutates, he said.Vir is developing contingency plans for running trials in Australia, New Zealand and South Africa if the outbreak isn’t active in North America in the summer, Scangos said.The two companies also differ on the merits of a cocktail approach.Regeneron and Vir, two of the companies at the forefront of the race to develop antibody-based therapies for COVID-19, have very different ideas about the best ways to discover and develop mAbs that could protect against or treat the disease.Vir is prioritizing a single antibody against an epitope that is conserved between the coronaviruses that cause COVID-19 and severe acute respiratory syndrome (SARS), while Regeneron is focused on cocktails of antibodies that are specific to COVID-19.Regeneron plans to start human trials in June, while Vir has stated that it expects to have its candidates in broad clinical trials this summer.“Because they are so specific,” antibodies targeting the novel coronavirus’ receptor binding domain are “orders of magnitude more potent than these cross-reacting type antibodies you can get from SARS-CoV-1 patients,” Yancopoulos said.Scangos added that Vir has “a whole other series of antibodies from SARS-CoV-2 patients that bind to different sites” that are “highly potent.”Yet the company has also developed additional antibodies that could be combined into a cocktail.
