Pfizer and Teva on November 21, 2006 announced that the companies reached an agreement that resolves litigation surrounding the drugs idarubicin and azithromycin, as well as issues relating to epirubicin. The resolution includes full releases between the parties and directs a payment as large as $70 million from Teva to Pfizer. The dispute between subsidiary companies Pharmacia (Pfizer) and Sicor (Teva) centered on Sicor’s sale of a generic form of the injectible anti-cancer drug idarubicin HCl (Pharmacia's IDAMYCIN PFS). Pfizer also filed suit against Teva for its sale of a generic form of the antibiotic azithromycin (Pfizer’s Zithromax). Under terms of the agreement Teva will continue its sale of generic idarubicin and azithromycin, and has a 2007 option to sell a generic version of epirubicin (Pfizer's ELLENCE), which is used in adjuvant therapy in patients that show evidence of axillary node tumor involvement following resection of primary breast cancer. Pfizer’s patent coverage of epirubicin is set to expire in August 2007.
