(AP) - TAKING OVER: Biogen Idec will take over full ownership of the multiple sclerosis treatment Tysabri from its partner Elan Corp. PLC in exchange for a $3.25 billion cash payment and royalties on future sales.
CAPITAL IDEA: The drug developers currently split earnings from Tysabri, but Elan said the new deal will give it capital for investing and growing its business.
DIRECT INJECT: Tysabri is a drug taken intravenously once a month to combat to treat a form of multiple sclerosis that cycles between stages of relapse and remission.
