epogen

Drug-makers Amgen and Johnson & Johnson are voluntarily recalling two brands of an injectable anemia medication because of the possibility that vials of it may also contain tiny glass flakes. The drug, Epoetin alfa, is marketed under the brand names Epogen and Procrit.

Amgen, the world's largest biotechnology company, reported fourth-quarter results that missed Wall Street's expectations, as a 2% increase in sales failed to translate into a stronger bottom line.

Pfizer may be hatching plans to sell "biosimilars," cheaper versions of biotech medicines, of drugs developed by the world's largest independent biotech Amgen. That's causing concern not just at Amgen, but at other biotechs that fear such competition.
