Common questions

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

October 2026. The next catalyst for Inhibrx Biosciences, Inc. is INBRX-106 (readout). That date is known to the month only. One further catalyst is scheduled after it. Dates are taken from FDA notices, company filings or ClinicalTrials.gov, and we do not publish a specific day when the source only gives a month or a quarter.

Has Inhibrx Biosciences, Inc. (INBX) had an FDA decision before?

Yes, 1 in our archive: 0 approval(s) and 1 Complete Response Letter(s). The most recent was on January 21, 2025 and was a Complete Response Letter. Each one has its own page with the source document and the share-price reaction we measured.

How do stocks like INBX move into an FDA decision?

We have no measured history for INBX itself. Across the whole study of 1,839 FDA decisions, the median stock rose 17.7% at its best point in the 120 trading days before the decision, but was only 2.0% higher the day before it. Most of the move happened before the answer arrived and was largely given back.

Where does this INBX 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.
