FDA approved the original biologics license application for SANTYL on June 4, 1965, sponsored by SMITH AND NEPHEW. FDA classed that submission a new molecular entity, which makes it the first approval of collagenase in any product. FDA’s record shows no approved efficacy supplement on the application since.

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.
FDA’s record shows no approved efficacy supplement on this application.

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.
