- Treatment with sotrovimab resulted in an 85% reduction in the risk of hospitalisation or death in high-risk adult outpatients compared to placebo, based on interim results from Phase 3 COMET-ICE trial
- In vitro data indicate sotrovimab maintains activity against all known variants of concern, including the variant from India
- Sotrovimab will be available for appropriate patients diagnosed with COVID-19 in the U.S. in the coming weeks
- Discussions with global regulators regarding authorisations in additional countries continue to advance
GlaxoSmithKline plc and Vir Biotechnology, Inc. announced the U.S. Food and Drug Administration (FDA) granted an Emergency Use Authorization (EUA) for sotrovimab (previously VIR-7831), an investigational single-dose monoclonal antibody, for the treatment of mild-to-moderate COVID-19 in adults and paediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalisation or death.
Adrienne E. Shapiro, M.D., Ph.D., an infectious disease specialist at Fred Hutchinson Cancer Research Center and investigator in the COMET-ICE trial, said: “Monoclonal antibodies like sotrovimab are potentially one of our most effective tools for fighting COVID-19. While preventive measures, including vaccines, can reduce the total number of cases, sotrovimab is an important treatment option for those who become ill with COVID-19 and are at high risk – allowing them to avoid hospitalisation or worse.”
George Scangos, Ph.D., Chief Executive Officer of Vir, said: “Our distinctive scientific approach has led to a single monoclonal antibody that, based on an interim analysis, resulted in an 85% reduction in all-cause hospitalisations or death, and has demonstrated, in vitro, that it retains activity against all known variants of concern, including the emerging variant from India. I believe that sotrovimab is a critical new treatment option in the fight against the current pandemic and potentially for future coronavirus outbreaks, as well. At Vir, our aim is not only to deliver a clinically effective therapy for COVID-19, but also to provide effective therapy against SARS-CoV-2 variants and potential pandemics of tomorrow.”
Dr Hal Barron, Chief Scientific Officer and President R&D, GSK, said: “The fast pace of COVID-19 vaccinations in the U.S. is encouraging, yet, despite these aggressive efforts, there is still a need to help prevent infected patients from developing complications. In just over a year since starting our collaboration and in less than 10 months since beginning clinical trials, we are delighted that, as of today, the benefits of this unique monoclonal antibody will now be available to patients in need.”
Sotrovimab has been granted an EUA by the FDA to facilitate the availability and use of this investigational monoclonal antibody for the treatment of COVID-19 in the U.S. while the pandemic remains a public health emergency. The FDA Fact Sheet for Healthcare Providers regarding the emergency use of sotrovimab reflects the recently updated definition of high risk for COVID-19 to include additional medical conditions and factors associated with increased risk for progression to severe disease. The EUA for sotrovimab also includes post-authorisation commitments as specified in the Letter of Authorization.
Sotrovimab is continuing to be studied in ongoing clinical trials. An analysis of safety and efficacy data at day 29 for the full population from the COMET-ICE trial is expected as early as the first half of 2021. GSK and Vir plan to submit a Biologics License Application (BLA) to the FDA in the second half of 2021.
