What “discontinued” means in FDA’s record
Drugs@FDA marks a product discontinued when it was never marketed, when it has been taken off the market, when it is made only for export, when it is made for military use, or when its approval was withdrawn for a reason other than safety or effectiveness. The record does not say which of those applies to a given product. The word on its own is not evidence that FDA found the drug unsafe.

Approved efficacy supplements
An efficacy supplement is how a sponsor asks FDA to approve a change that needs clinical evidence — most often a new indication. FDA’s record gives each one a submission number, a date and a review priority. It does not say what any supplement approved, so neither does this page. The approval letter and label for each are on accessdata.fda.gov under the application number.
| Approved | Supplement | Review |

FDA records other approved supplements on this application, by the class code it assigns them: Manufacturing (CMC) 8 · Labeling 5 · REMS 2. Those are changes to the label or to how the drug is made rather than new clinical evidence, so they are counted here and not listed.

An approval date is the start of the question, not the end
What a drug is worth to the company that owns it depends on what else is in the pipeline, how much cash is behind it and who else is running the same trial. FuzeBio reads a biotech end to end on demand — pipeline in plain English, trial design and endpoints, competitors, the cash position, and a valuation with its assumptions on the page.
