Teaching Old Drugs New Tricks

First, a couple of comments on Supplement 9 (September) of Orange Book Volume 39 (2019): There were 60 new patents listed, including one process patent.

What was more interesting was the addition of  fifteen  new Use Codes (U-2588 to U-2602) to the new and already-listed BYDUREON BCISE patents. Fifteen? Where did those come from? A look at the Drugs@FDA database showed that BYDUREON BCISE received approval for  seven  supplements on July 25. Quite a load! So those approvals might have been the source of the new Use Codes. But that is not the end of the story. The very next month, the FDA’s Supplement 9 data showed that ten of the BYDURE
