The biggest loser would likely be Orexigen as it has so much more time before it ever goes to market. All of these have been long awaited by doctors and their patients with diabetes and heart problems as even losing 5% of body weight helps lessen the risks associated with these conditions. As for vanity, ah, vanity that is a huge market and patients will ask their doctors for these treatments.  As the old saying goes, “You can never be too rich or too thin,” I think Arena has the best likelihood of making you both.                                  Big Fat BiosBy AnnaLisa Kraft — July 12, 2012
