4. Strategic Considerations and Industry Trends
4.1 Regulatory Developments
- FDA Pediatric Indication: Approved in May 2022 for adolescents aged 12–17.
- EMA & Other Regulators: Approvals in Europe, Japan, and Canada are either granted or pending, expanding market opportunity.
4.2 Impact of Oral CGRP Antagonists
The introduction of oral preventive agents like rimegepant and zavegepant could mitigate injectable CGRP inhibitor growth. However, injectable mAbs like Aimovig retain advantages in long-term efficacy demonstrated in clinical trials.
4.3 Digital and Data Strategy
Integration with digital health tools for adherence and real-world monitoring enhances competitive positioning. Data sharing from registries influences prescriber confidence.
