Vir Biotechnology Announces First Marketing Authorization for its First Commercial Product, Sotrovimab, Granted in Australia
The TGA had previously granted sotrovimab a provisional determination in April, which provides a mechanism for accelerating the provisional marketing authorization of promising new medicines. This approval pathway allows companies to apply for registration of medicines for conditions with high unmet clinical need based on promising early clinical data.
Globally, sotrovimab is authorized for emergency use in the
The regulatory applications currently under assessment around the world, include results of the Phase 3 COMET-ICE (COVID-19 Monoclonal antibody Efficacy Trial - Intent to Care Early) trial, which resulted in a 79% reduction (adjusted relative risk reduction) (p<0.001) in all-cause 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.
In vitro data, published in bioRxiv also demonstrate that sotrovimab retains activity against currently circulating variants of concern and interest of the SARS-CoV-2 virus including Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Delta Plus (AY.1 or AY.2), Epsilon (B.1.427/B.1.429), Eta (B.1.525), Gamma (P.1), Iota (B.1.526), Kappa (B.1.617.1) and Lambda (C.37), as well as new variants from Bristol (B.1.1.7+E484K) and Cameroon (B.1.619), which predominantly includes both N440K and E484K mutations that may lead to reduced activity for other neutralizing monoclonal antibodies against the SARS-CoV-2 virus.

About Sotrovimab (Outside of
Sotrovimab is an investigational SARS-CoV-2 monoclonal antibody. Preclinical data suggest it has the potential to both block viral entry into healthy cells and clear infected cells. 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, also has 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.

Minimum Product Information
XEVUDY ▼ (sotrovimab) Concentrated injection solution for infusion
Indications: XEVUDY has provisional approval for the treatment of adults and adolescents (aged 12 years and over and weighing at least 40 kg) with coronavirus disease 2019 (COVID-19) who do not require initiation of oxygen due to COVID-19 and who are at increased risk of progression to hospitalization or death. The decision has been made on the basis of short term efficacy and safety data. Continued approval of this indication depends on the evidence of longer term efficacy and safety from ongoing clinical trials and post-market assessment.
Contraindications: Hypersensitivity to the active substance or any of the excipients
Precautions: Hypersensitivity reactions. In a study in patients hospitalized with COVID-19, hypersensitivity reactions, including serious reactions such as anaphylaxis, have been reported following infusion of sotrovimab. If signs and symptoms of a clinically significant hypersensitivity reaction occur, immediately discontinue administration and initiate appropriate supportive care.
In COMET-ICE, mild to moderate hypersensitivity reactions have been observed. If mild to moderate hypersensitivity reactions occur, consider slowing or stopping the infusion along with appropriate supportive care. Pregnancy: Category B2. Lactation: No data in human milk. Fertility: No data in humans. Pediatric use: Safety and efficacy in children under 12 years of age or weighing less than 40kg has not yet been established. For further details, please refer to the full Product Information (PI).
Interactions: No formal interaction studies have been performed. The efficacy and safety of sotrovimab in subjects who have received a COVID-19 vaccine at any time prior to its administration has not been established. The receipt of a COVID-19 vaccine within 48 hours prior to, or 4 weeks following treatment with XEVUDY has not been studied.
Adverse reactions: Diarrhea, hypersensitivity reactions (includes rash, dermatitis contact, skin reaction, hypersensitivity, multiple allergies, infusion-related reaction and bronchospasm). One case of anaphylaxis was reported following infusion of sotrovimab in a study in hospitalized patients; the patient received epinephrine and the event resolved. This is not a complete list, see full PI.
Dosage and Administration: Adults and adolescents (12 years or older and weighing at least 40 kg): recommended dose is a single 500 mg dose administered as an intravenous infusion over 30 minutes. It is recommended that XEVUDY is administered within 5 days of onset of symptoms of COVID-19. XEVUDY must be diluted prior to administration and must not be administered as an intravenous push or bolus injection. XEVUDY should be administered in healthcare facilities in which patients can be monitored during and for one hour after administration of XEVUDY. As part of risk stratification of patients, the pivotal consideration is the comorbidities, alongside age, particularly multiple comorbidities. XEVUDY should not be used in patients hospitalized due to COVID-19. For further details, please refer to the full PI.

Sotrovimab is authorized only for the duration of the declaration that circumstances exist justifying the of the emergency use of sotrovimab under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the is terminated or revoked sooner.
Authorized Use in
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.
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.
