Material Changes and Regulatory Developments
- FDA Advisory Committee Vote: The US FDA Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously (12-0) that data support the effectiveness of GSK's RSV older adult vaccine candidate. The committee voted 10-2 that data support the safety of the vaccine.
- Approval Timeline: The FDA is expected to make a final decision on US approval by May 3, 2023. If approved, this would be the first RSV vaccine approved for older adults.
- Global Regulatory Status: The vaccine candidate is under review by the European Medicines Agency, Japan's Ministry of Health, Labour and Welfare, and other regulators, with decisions expected in 2023.
- Clinical Data: The vote was based on pivotal data from the AReSVi-006 phase III trial, recently published in the New England Journal of Medicine, and data on concomitant administration with seasonal influenza vaccines.
Outlook, Risks, and Management Commentary
Phil Dormitzer, Global Head of Vaccines R&D, stated that the vote is a critical step toward delivering one of the world's first RSV vaccines, which could significantly impact public health given the burden of RSV on older adults and healthcare systems. The vaccine candidate contains a recombinant subunit prefusion RSV F glycoprotein antigen combined with GSK's proprietary AS01 E adjuvant.
Risks and Contingencies: The filing includes a cautionary statement regarding forward-looking statements. Actual results may differ materially due to risks described in GSK's Annual Report on Form 20-F for 2021, Q4 2022 results, and potential impacts of the COVID-19 pandemic. The VRBPAC vote is non-binding, and the final approval decision rests with the FDA.
