When: November 4, 2007
Where: Orlando, Florida
Who: People with heart problems
What: A new blood thinner proved better than Plavix, one of the world's top-selling drugs, at preventing heart problems after procedures to open clogged arteries. But the new drug also raised the risk of serious bleeding.
Why: People given the experimental drug, prasugrel, were nearly 20 percent less likely to suffer one of the problems in a combined measure (heart attack, stroke or heart-related death) than those given Plavix, a drug that millions of Americans take to prevent blood clots that cause these events.
