Cross-agency comparison: 🇪🇺 EMA leads with 82 documents in 90 days

FDA vs EMA vs MHRA vs Health Canada — who's most active?

The comparison suggests that EMA is currently the most active environment by volume, with MHRA and Health Canada also producing a relatively steady stream of output, while FDA appears less document-heavy over this period; this may indicate that Europe and Canada are evolving guidance and expectations more quickly than the U.S. in this window. Sponsors should consider treating multi-market filing strategy as a moving target, with more resources devoted to monitoring, gap analysis, and dossier adaptation for EMA-led and UK/Canada-aligned requirements, while still preserving enough flexibility to absorb later FDA-specific shifts without reworking the core submission package.
