Navigating US FDA Approval Standards for Rare Diseases

From 2024–2026, FDA has introduced significant reforms for rare disease approvals including a single‑trial and confirmatory evidence pathway and a new Plausible Mechanism Framework that could reshape development for ultra‑rare genetic therapies.

We will walk through what has changed, what remains unclear, and the concrete steps rare disease teams can take to improve the probability of approval grounded in recent examples from both successful and unsuccessful programs.
