    LONDON and SAN FRANCISCO, Nov. 17, 2021 (GLOBE NEWSWIRE) -- GlaxoSmithKline plc (LSE/NYSE: GSK) and Vir Biotechnology, Inc. (Nasdaq: VIR) today announced US government contracts totaling approximately $1 billion1 (USD) to purchase sotrovimab, an investigational monoclonal antibody for the early treatment of COVID-19, which the US Food and Drug Administration (FDA) granted Emergency Use Authorization (EUA) in May 2021. GSK will supply these doses to the US government by December 17, 2021, enabling further expanded nationwide access to sotrovimab for patients.

    In addition to the doses that will be supplied this year, the US government will have the option to purchase additional doses through March 2022.

    Including the contracts announced today, GSK and Vir have received binding agreements for the sale of more than 750,000 doses of sotrovimab worldwide, with additional doses reserved through other agreements including the previously announced Joint Procurement Agreement with the European Commission.

    Sotrovimab is an FDA EUA-authorized 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 pediatric patients (12 years of age and older weighing at least 40 kg) with positive test results for COVID-19, and who are at high risk for progression to severe COVID-19, including hospitalization or death.

    Dr. Hal Barron, Chief Scientific Officer and President R&D, GSK, said: “Given the large number of patients who continue to become ill with COVID-19 across many regions in the US, there is an ongoing need for access to effective treatments. We are proud to work with the US government to help make sotrovimab available for these patients.”

    George Scangos, Ph.D., Chief Executive Officer of Vir, said: “Monoclonal antibodies play an essential role in the treatment of certain patients with COVID-19, and we’re grateful that this agreement will allow more healthcare providers and patients who are at high risk for progression to severe COVID-19 to access sotrovimab. Given ongoing evidence, which demonstrates its ability to maintain activity against the tested circulating variants of concern, including Delta, we are confident sotrovimab will continue to be important in the fight against COVID-19.”

    The US government purchase was funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the U.S. Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response through Department of Defense – contract numbers W58P0521C0008 and W58P0522C0002.

    In June 2021, GSK and Vir announced confirmatory full results for the COMET-ICE Phase 3 trial, which resulted in a 79% reduction (adjusted relative risk reduction) (p<0.001) in hospitalizations for more than 24 hours or death due to any cause by Day 29 compared to placebo, meeting the primary endpoint of the trial.

    The companies also recently announced headline data from the randomized, multi-center, open-label COMET-TAIL Phase 3 trial, which achieved its primary endpoint, demonstrating intramuscular (IM) administration of sotrovimab was non-inferior to IV administration for the early treatment of mild-to-moderate COVID-19 in high-risk, non-hospitalized adults and adolescents (12 years of age and older).  The companies plan to progress regulatory submissions globally.

    GSK and Vir are committed to 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. Updated in vitro data, published in bioRxiv, demonstrate that sotrovimab retains activity against all current variants of concern and interest of the SARS-CoV-2 virus as defined by the World Health Organization, plus others, including, but not limited to, Delta (B.1.617.2), Delta Plus (AY.1 or AY.2) and Mu (B.1.621).

    About sotrovimab
    Sotrovimab is an investigational SARS-CoV-2 neutralizing monoclonal antibody. The antibody binds to an epitope on SARS-CoV-2 that is 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’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 authorized for emergency use in the United States and received a positive scientific opinion under Article 5(3) of Regulation 726/2004 from the Committee for Human Medicinal Products (CHMP) in the European Union (EU). Sotrovimab has been granted a provisional marketing authorization in Australia and a conditional marketing authorization in Saudi Arabia. In Japan, it has been approved via the Special Approval for Emergency Pathway. Temporary authorizations have been granted in Bahrain, Brazil, Canada, Egypt, Italy, Kuwait, Oman, Qatar, Singapore, Switzerland, Thailand and the United Arab Emirates (UAE).
    • Sotrovimab is supplied in several countries around the world, including through national agreements in the United States, Japan, Australia, Canada, Singapore and the UAE. We have also signed a Joint Procurement Agreement with the European Commission to supply doses of sotrovimab. Additional agreements are yet to be announced due to confidentiality or regulatory requirements.

    About the sotrovimab clinical development program

    • COMET-ICE: a Phase 3, multi-center, double-blind, placebo-controlled trial investigated IV infusion of sotrovimab in adults with mild-to-moderate COVID-19 at high risk of progression to severe disease, who are not hospitalized and not requiring oxygen. The final COMET-ICE trial results in the full trial population of 1,057 participants demonstrated a 79% reduction (adjusted relative risk reduction) (p<0.001) in hospitalization for more than 24 hours or death due to any cause by Day 29 compared to placebo, meeting the primary endpoint of the trial. Interim data were published in The New England Journal of Medicine on October 27, 2021 and final data were pre-published on November 8, 2021 on medRxiv.
    • COMET-TAIL: a Phase 3, randomized, multi-center, open-label, non-inferiority trial of IM versus IV administration of sotrovimab for the early treatment of mild-to-moderate COVID-19 in high-risk non-hospitalized adult and pediatric patients (12 years of age and older). The trial’s primary endpoint was met, and headline data demonstrated that intramuscularly administered sotrovimab was non-inferior and offered similar efficacy to intravenous administration for high-risk populations. The companies plan to submit the full COMET-TAIL data set to a peer-reviewed journal for publication in the first quarter of 2022.
    • COMET-PEAK: a Phase 2, randomized, multi-center, parallel group trial evaluating IV and IM administration of sotrovimab in outpatients with mild-to-moderate COVID-19. Data available to date from open-label Part B of the trial (500mg IV vs. 500mg IM) demonstrated equivalence on the virological response between the IM and IV arms. The companies plan to submit the full COMET-PEAK data set to a peer-reviewed journal for publication.
    • GSK and Vir are also partnering to investigate the use of sotrovimab in uninfected immunocompromised adults to determine whether sotrovimab can prevent symptomatic COVID-19 infection. GSK and Vir are supporting investigator-sponsored studies and fostering scientific collaborations with both experienced investigators and networks, who are involved in the continuum of care of immunocompromised patients, to understand the role sotrovimab for prophylaxis could play in this population. Discussions with regulatory authorities regarding the prophylaxis program will take place in due course.

    Authorized Use
    The U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) to permit the emergency use of the unapproved product sotrovimab for the treatment of mild-to-moderate coronavirus disease 2019 (COVID-19) in adults and pediatric 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 hospitalization or death.

    Limitations of Authorized Use
    Sotrovimab is not authorized for use in patients:

    • who are hospitalized due to COVID-19, OR
    • who require oxygen therapy due to COVID-19, OR
    • who require an increase in baseline oxygen flow rate due to COVID-19 (in those on chronic oxygen therapy due to underlying non-COVID-19 related comorbidity)

    Benefit of treatment with sotrovimab has not been observed in patients hospitalized due to COVID‑19. SARS-CoV-2 monoclonal antibodies may be associated with worse clinical outcomes when administered to hospitalized patients with COVID‑19 requiring high flow oxygen or mechanical ventilation.

    Important Safety Information

    CONTRAINDICATIONS
    Sotrovimab is contraindicated in patients who have a history of anaphylaxis to sotrovimab or to any of the excipients in the formulation.

    WARNINGS AND PRECAUTIONS
    There are limited clinical data available for sotrovimab. Serious and unexpected adverse events may occur that have not been previously reported with sotrovimab use.

    Hypersensitivity Including Anaphylaxis and Infusion-Related Reactions
    Serious hypersensitivity reactions, including anaphylaxis, have been observed with administration of sotrovimab. If signs and symptoms of a clinically significant hypersensitivity reaction or anaphylaxis occur, immediately discontinue administration and initiate appropriate medications and/or supportive care.

    Infusion-related reactions, occurring during the infusion and up to 24 hours after the infusion, have been observed with administration of sotrovimab. These reactions may be severe or life threatening.

    Signs and symptoms of infusion-related reactions may include: fever, difficulty breathing, reduced oxygen saturation, chills, fatigue, arrhythmia (eg, atrial fibrillation, sinus tachycardia, bradycardia), chest pain or discomfort, weakness, altered mental status, nausea, headache, bronchospasm, hypotension, hypertension, angioedema, throat irritation, rash including urticaria, pruritus, myalgia, vaso-vagal reactions (eg, pre-syncope, syncope), dizziness and diaphoresis.

    Consider slowing or stopping the infusion and administer appropriate medications and/or supportive care if an infusion-related reaction occurs.

    Hypersensitivity reactions occurring more than 24 hours after the infusion have also been reported with the use of SARS-CoV-2 monoclonal antibodies under Emergency Use Authorization.

    Clinical Worsening After SARS-CoV-2 Monoclonal Antibody Administration
    Clinical worsening of COVID‑19 after administration of SARS-CoV-2 monoclonal antibody treatment has been reported and may include signs or symptoms of fever, hypoxia or increased respiratory difficulty, arrhythmia (eg, atrial fibrillation, tachycardia, bradycardia), fatigue, and altered mental status. Some of these events required hospitalization. It is not known if these events were related to SARS-CoV-2 monoclonal antibody use or were due to progression of COVID‑19.

    Limitations of Benefit and Potential for Risk in Patients with Severe COVID‑19
    Benefit of treatment with sotrovimab has not been observed in patients hospitalized due to COVID‑19. SARS-CoV-2 monoclonal antibodies may be associated with worse clinical outcomes when administered to hospitalized patients with COVID‑19 requiring high-flow oxygen or mechanical ventilation. Therefore, sotrovimab is not authorized for use in patients: who are hospitalized due to COVID‑19, OR who require oxygen therapy due to COVID‑19, OR who require an increase in baseline oxygen flow rate due to COVID‑19 in those on chronic oxygen therapy due to underlying non‑COVID‑19 related comorbidity.

    ADVERSE EVENTS
    Hypersensitivity adverse reactions have been observed in 2% of patients treated with sotrovimab and 1% with placebo in COMET-ICE.

    The most common treatment-emergent adverse events observed in the sotrovimab treatment group in COMET-ICE were rash (1%) and diarrhea (2%), all of which were Grade 1 (mild) or Grade 2 (moderate). No other treatment-emergent adverse events were reported at a higher rate with sotrovimab compared to placebo.

    USE IN SPECIFIC POPULATIONS

    Pregnancy
    There are insufficient data to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcome. Sotrovimab should be used during pregnancy only if the potential benefit justifies the potential risk for the mother and the fetus.

    Lactation
    There are no available data on the presence of sotrovimab in human milk, the effects on the breastfed infant, or the effects on milk production. Individuals with COVID-19 who are breastfeeding should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19.
