FDA actions.

What this does not cover

The calendar reads government registers and nothing else. It has no view of anything a company has not filed, and no free source publishes pending FDA goal dates, so approval decision dates are absent by construction rather than by omission. An empty week is not evidence that nothing is scheduled that week. Read a gap as a gap in the registers.

Complete response letters are never published here. Neither are live offerings. Both exclusions are deliberate and permanent. The methodology page sets out every source, every gate and the current drop rate.

How it is compiled

Rows are written automatically from primary documents once a day. Nobody reviews each row before it appears. Every sentence is composed from structured fields taken out of the filing, never from the wording of the source, and each one carries the date on which the claim was made so it stays true after a date slips.

Not investment advice

Nothing here is a recommendation to buy or sell anything, and none of it is tailored to any reader. This page is identical for every visitor. It reports what public registers say, and public registers are wrong often enough that you should check the linked document before you act on a row.

Corrections and takedown

Write to calendar@julienwillard.com with the reference identifier of the row. Corrections and takedown requests are answered within two business days. No call is needed and none will be asked for.

When a row changes

A row whose date moves keeps its identity and gains a note saying where it moved from, so a calendar subscription updates the event in place instead of adding a second one. A withdrawn row stays visible for 30 days, struck through, and is listed on the changes page. Nothing disappears without a record.
