Material Changes and Regulatory Developments
- Regulatory Submission: The FDA has accepted GSK's application to review an expanded indication for Arexvy targeting adults aged 18-49 with risk factors (e.g., COPD, asthma, heart failure).

Guidance, Outlook, and Risks
- Timeline: An FDA decision on the expanded indication is anticipated in the first half of 2026 (H1 2026).
- Global Strategy: GSK is continuing to seek expanded indications for Arexvy in other geographies, including the European Economic Area and Japan.
