Wyeth Sues J&J over Drug Used in Cypher

Bloomberg News reports that Wyeth yesterday filed suit against Johnson & Johnson, accusing it of breaching a contract allowing it to use Wyeth's sirolimus drug with J&J's Cypher drug-eluting stent. J&J denies the allegations, the details of which are blacked out in the public version of the document. The lawsuit if pursued would take a few years to play out, but could potentially be devastating for J&J's drug-eluting stent platform.
