Common questions

When is the next FDA decision or readout for MBX Biosciences, Inc. (MBX)?

May 2028. The next catalyst for MBX Biosciences, Inc. is MBX 2109 (readout). That date is known to the month 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 Dates are taken from FDA notices, company filings or ClinicalTrials.gov, and we do not publish a specific day when the source only gives a month or a quarter.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 MBX move into an FDA decision?

We have no measured history for MBX itself. Across the whole study of 1,883 FDA decisions, the median stock rose 18.0% at its best point in the 120 trading days before the decision, but was only 2.4% higher the day before it. Most of the move happened before the answer arrived and was largely given back.

Where does this MBX 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.
