San Diego Life Sciences Roundup: Amylin Buyout, PDUFA, & More

Amylin’s acquisition topped the news out of San Diego’s life sciences sector in the week before the July 4 holiday. But there were plenty of other developments as well. Here’s my rundown:

—What a long, strange trip it’s been.

In passing the measure, Congress left plenty of time for the FDA to implement new programs before the existing prescription drug act’s authorization expires on September 30. One key provision of the legislation is entitled “Generating … Next Page »
