Watson Confirms Filing of Abbreviated New Drug Application for Generic Enablex(R)

- Paragraph IV Litigation Underway -

CORONA, Calif., April 28 /PRNewswire-FirstCall/ -- Watson Pharmaceuticals, Inc. (NYSE: WPI), a leading specialty pharmaceutical company, today confirmed that it has filed an Abbreviated New Drug Application (ANDA) with the U.S. Food and Drug Administration seeking approval to market its darifenacin hydrobromide extended-release 7.5 mg and 15 mg product prior to the expiration of a patent owned by Novartis AG. Watson's darifenacin hydrobromide extended-release product is the generic version of Novartis AG's Enablex(R) which is indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency and frequency.

Novartis AG filed suit against Watson on April 24, 2009 in the U.S. District Court for the District ofDelaware seeking to prevent Watson from commercializing its products prior to expiration of U.S. patent number 6,106,864. Novartis AG's suit was filed under the provisions of the Hatch Waxman Act, resulting in a stay of final FDA approval of Watson's ANDA for up to 30 months or until final resolution of the matter before the court, whichever occurs sooner.

For the twelve-months ended December 31, 2008, Enablex(R) had total U.S. sales of approximately $220 million, according to IMS Health data.
