Common questions

When is the next FDA decision or readout for Xenon Pharmaceuticals Inc. (XENE)?

Q3 2026. The next catalyst for Xenon Pharmaceuticals Inc. is XEN1701 readout. That date is known to the quarter only. Dates are taken from FDA notices, company filings or ClinicalTrials.gov, and we do not publish a specific day when the source only gives a month or a quarter.

How do stocks like XENE move into an FDA decision?

We have no measured history for XENE itself. Across the whole study of 1,855 FDA decisions, the median stock rose 17.9% at its best point in the 120 trading days before the decision, but was only 2.2% higher the day before it. Most of the move happened before the answer arrived and was largely given back.

Where does this XENE data come from?

FDA publications, company filings with the SEC, company press releases and ClinicalTrials.gov, with share prices measured from daily closing data. Every date and outcome links the document it came from. Where an outcome was inferred from the price reaction rather than read from a filing, the page says so on its face.
