The market for drugs to treat diabetes — especially Type 2 diabetes — has shown quite a bit of activity lately. At the end of January, the Food and Drug Administration approved Bydureon (exenatide), a once-weekly version of the drug Byetta, which was originally developed by Alkermes and subsequently developed further under an alliance between Amylin Pharmaceuticals and Eli Lilly that the two companies formed in 2002. In November 2011, however, Amylin and Lilly terminated their alliance in the wake of an announced diabetes drug partnership between Lilly and Boehringer Ingelheim.
