Syncing Global Regulatory Filings Across FDA, EMA, and PMDA with AJ Acker

What does it actually take to navigate global regulatory filings across the FDA, EMA, and PMDA, and why do so many programs stumble despite technically harmonized dossiers? AJ Acker draws on about 30 years of rare disease regulatory experience to break down the real differences between regions and the strategies that drive successful multi-regional approvals.AJ discusses why ICH compliance doesn't equal regulatory alignment, how Japan's evolving regulatory landscape creates both opportunity and complexity, and why the preparation that starts early in development (not at submission) is what determines whether a program achieves tight global approval timelines.A few of AJ's key takeaways:FDA, EMA, and PMDA share the same goal but ask fundamentally different questions — sponsors need to understand each lens, not just the shared scienceICH harmonization provides a common foundation, but technical alignment is not regulatory alignment — region-specific engagement is essentialStart planning for all three regions early, especially Japan — PMDA will ask why they weren't included in early developmentExpect different regulators to want different endpoints from the same data — early conversations prevent study design misalignmentLocal regulatory experts and ex-regulators are most valuable as strategic advisors and early warning systems, not just document producersSimultaneous filings are becoming the norm, but resource planning for parallel review cycles is criticalAI is emerging as a tool for sharpening submission strategy — not replacing expertise, but catching gaps human reviewers might missAbout AJ AckerAJ Acker is Senior Vice President of Regulatory, Quality & Clinical Safety at Annexon Biosciences.
