Synopsis :

GlaxoSmithKline plc (LSE/NYSE: GSK) and Vir Biotechnology, Inc. (Nasdaq: VIR) announced that the US Government will purchase an additional 600,000 doses of sotrovimab, an investigational monoclonal antibody for the early treatment of COVID-19, enabling further nationwide access to sotrovimab for patients. The additional 600,000 doses will be delivered throughout the first quarter of 2022. This agreement is an amendment to earlier commitments announced with the US Government in November 2021.

Including the commitments announced today, GSK and Vir have received binding agreements for the sale of approximately 1.7 million doses of sotrovimab worldwide. In addition, today’s agreement also includes the option for the US government to purchase further additional doses in the second quarter of 2022.

Sotrovimab, which was granted Emergency Use Authorization (EUA) by the US Food and Drug Administration (FDA) in May 2021, is an investigational single-dose intravenous (IV) infusion SARS-CoV-2 monoclonal antibody. Under the EUA, sotrovimab can be used 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.

GSK and Vir expect to manufacture approximately 2 million doses globally in the first half of 2022 and additional doses in the second half of the year.

Maya Martinez-Davis, President, US Pharmaceuticals, GSK, said: “We are proud to continue to work with the US government to bring sotrovimab to patients who need it, especially as the Omicron variant continues to grow in prevalence across the country. We understand the role we can play in supporting the ongoing pandemic response, and our teams are working with urgency to explore options to expand our supply capacity so we can support more patients in 2022.”

George Scangos, PhD, chief executive officer of Vir, said: “As the Omicron variant continues its rapid spread alongside the still prevalent Delta variant, we are pleased to once again work with the US government to provide more access to sotrovimab for people in the US at high risk of progression to severe COVID-19. Data from multiple pseudo-virus and live virus preclinical studies, generated by industry and academia, continue to demonstrate that sotrovimab retains activity against all tested variants of concern and interest. We are proud of our ongoing contributions to the fight against the COVID-19 pandemic here in the US and around the world.”

The Biomedical Advanced Research and Development Authority (BARDA), part of the Department of Health and Human Services (HHS) Office of the Assistant Secretary for Preparedness and Response (ASPR), collaborated with the Department of Defense Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) and Army Contracting Command to purchase contract numbers W58P0521C0008 and W58P0522C0002.

In June 2021, GSK and Vir announced confirmatory full results for the COMET-ICE Phase III trial examining use of sotrovimab for early treatment of mild-to-moderate COVID-19 in high-risk, non-hospitalised adults. The trial met the primary endpoint with a 79% reduction (adjusted relative risk reduction) (p<0.001) in all-cause hospitalisations for more than 24 hours or death due to any cause by Day 29 compared to placebo. In absolute numbers, 30 (6%) of the 529 patients in the placebo arm progressed, compared to six (1%) of the 528 patients receiving sotrovimab. In clinical trials conducted to date, sotrovimab has been well-tolerated. The most common adverse reactions are hypersensitivity and infusion-related reactions, seen in approximately 2% and 1% of cases, respectively.

GSK and Vir are committed to the ongoing evaluation of sotrovimab as the COVID-19 landscape continues to evolve at different rates across the globe and new variants of concern and interest emerge. Preclinical pseudo-virus data, published in bioRxiv, demonstrate that sotrovimab retains activity against all tested variants of concern and interest of the SARS-CoV-2 virus as defined by the World Health Organization, including, but not limited to, Omicron (B.1.1.529), Delta (B.1.617.2), Delta Plus (AY.1 or AY.2) and Mu (B.1.621). Preclinical live virus testing has also been completed with data, recently published in bioRxiv, further demonstrating that sotrovimab retains activity against the Omicron variant.

About Sotrovimab

Sotrovimab is an investigational SARS-CoV-2 neutralising monoclonal antibody. The antibody binds to an epitope on SARS-CoV-2 shared with SARS-CoV-1 (the virus that causes SARS), indicating that the epitope is highly conserved, which may make it more difficult for resistance to develop. Sotrovimab, which incorporates Xencor, Inc.’s Xtend™ technology, has also been designed to achieve high concentration in the lungs to ensure optimal penetration into airway tissues affected by SARS-CoV-2 and to have an extended half-life.

About global access to sotrovimab

Sotrovimab is authorised for emergency use in the US and has been granted a marketing authorisation in the EU, conditional marketing authorisation in Great Britain, provisional marketing authorisation in Australia, and conditional marketing authorisation in Saudi Arabia. It has also been approved via Japan’s Special Approval for Emergency Pathway. Temporary authorisations for sotrovimab have also been granted in 12 other countries.

Sotrovimab is supplied in several countries worldwide, including through national agreements in the US, UK, Japan, Australia, Canada, Singapore, Switzerland, and the United Arab Emirates. The companies are also supplying sotrovimab to participating Member States of the EU through a Joint Procurement Agreement with the European Commission. Additional agreements are yet to be disclosed due to confidentiality or regulatory requirements.

Sotrovimab in the United States

The following is a summary of information for sotrovimab. Healthcare providers in the US should review the Fact Sheets for information about the authorized use of sotrovimab and mandatory requirements of the EUA. Please see the Food and Drug Administration (FDA) Letter of Authorization, full Fact Sheet for Healthcare Providers and full Fact Sheet for Patients, Parents, and Caregivers.

Sotrovimab has been authorized by the US FDA for the emergency use described below. Sotrovimab is not FDA-approved for this use.

About the GSK and Vir collaboration

In April 2020, GSK and Vir entered into a collaboration to research and develop solutions for coronaviruses, including SARS-CoV-2, the virus that causes COVID-19. The collaboration uses Vir’s proprietary monoclonal antibody platform technology to accelerate existing and identify new anti-viral antibodies that could be used as therapeutic or preventive 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 commitment to tackling COVID-19

GSK’s response to COVID-19 has been one of the broadest in the industry, with potential treatments in addition to the Company’s vaccine candidates in development with partner organisations.

GSK is collaborating with several organisations on COVID-19 vaccines by providing access to its adjuvant technology. The Company is working with Sanofi SA, Medicago Inc. and SK bioscience Co., Ltd. to develop adjuvanted, protein-based vaccine candidates, and all are now in phase III clinical trials. The use of an adjuvant can be of particular importance in a pandemic since it may reduce the amount of vaccine protein required per dose, allowing more vaccine doses to be produced and contributing to protecting more people in need.

GSK is also working with mRNA specialist CureVac NV to jointly develop next-generation, optimised mRNA vaccines for COVID-19 with the potential to address multiple emerging variants in one vaccine.

GSK is also exploring treatments for COVID-19 patients, collaborating with Vir Biotechnology to investigate monoclonal antibodies that could be used as therapeutic or preventive options for COVID-19.

Vir’s commitment to COVID-19

Vir was founded with the mission of addressing the world’s most serious infectious diseases. In 2020, Vir responded rapidly to the COVID-19 pandemic by leveraging our unique scientific insights and industry-leading antibody platform to explore multiple monoclonal antibodies as potential therapeutic or preventive options for COVID-19. Sotrovimab is the first SARS-CoV-2-targeting antibody Vir advanced into the clinic. It was carefully selected for its demonstrated promise in preclinical research, including an anticipated high barrier to resistance and potential ability to both block the virus from entering healthy cells and clear infected cells. Vir is continuing to pursue novel therapeutic and prophylactic solutions to combat SARS-CoV-2 and future coronavirus pandemics, both independently and in collaboration with its partners.
