Biogen Idec seeks FDA OK for new MS drug

Biogen Idec Inc., which cemented its place as the dominant multiple sclerosis drug maker in March when it won US approval to sell an MS pill, said Tuesday it has applied to the Food and Drug Administration to market a third injectable MS drug.

The drug, called Plegridy, is a new version of the Weston biotechnology company’s first — and hugely successful — MS treatment, Avonex. While both drugs have the same active ingredient, interferon beta, Biogen Idec has attached a polymer called polyethylene glycol, or peg, to Plegridy that increases the exposure of the drug, allowing patients to take doses less frequently.
