Questions

How many FDA decisions are scheduled for September 2026?
9 tracked PDUFA events fall in September 2026: 2 decided so far and 7 still ahead, plus 0 expected without a company-disclosed day. The FDA does not publish a forward calendar; every date here comes from a company filing or FDA notice.
Can these dates change?
Yes. A PDUFA date is the FDA's review goal, not a fixed announcement date. The agency can decide early, and it can extend the date by three months when a sponsor submits a major amendment during review.
