Material Changes and Developments
- Regulatory Acceptance: The MHLW has accepted GSK's application to expand Arexvy use to adults aged 18-49 at increased risk of severe RSV disease.
- Market Position: If approved, Arexvy would be the first RSV vaccine available in Japan for this specific demographic.

Outlook, Management Commentary, and Risks
Management Commentary: The submission is supported by positive Phase IIIb data (Trial NCT06389487) demonstrating a non-inferior immune response in the 18-49 age group compared to adults aged 60 and above. Safety and reactogenicity data were consistent with the initial approval program.
Future Outlook: GSK is the first company to seek this specific approval in Japan. Regulatory submissions to expand indications are ongoing in other geographies, including the US and Europe.
Risks and Contingencies: The filing includes a standard cautionary statement that forward-looking statements are subject to risks and uncertainties. Actual results may differ materially from projections due to factors described in GSK's 2024 Annual Report on Form 20-F and Q1 2025 results. Additionally, as with any vaccine, a protective immune response may not be elicited in all vaccinees.
