Surprise! A Food and Drug Administration advisory panel is backing approval for a blood-clotting drug being developed by GlaxoSmithKline and a San Diego firm.
The advisors voted unanimously today to recommend approval for Promacta to treat an immune system disorder. That's a bit of a surprise given that the FDA staff said the data indicated that the drug didn't work any better than a placebo in clinical testing.
Shares of GlaxoSmithKline, which is a much bigger company, also rose on the action by the Oncologic Drugs Advisory Committee, rising little more than 1 percent.
