Biogen Idec readies its next move

Company’s hopes for market dominance hinge on approval of oral MS treatment

The company also pulled a powerful multiple sclerosis treatment from the market, relaunched it, and turned the drug into a blockbuster that is ringing up annual sales of more than $1 billion.
