Allergan Sues Watson Over Sanctura Incontinence Drug
Allergan Inc. (AGN), the maker of wrinkle- smoothing Botox, sued Watson Pharmaceuticals Inc., alleging infringement of a U.S. patent for Sanctura XR, a prescription medicine used to treat overactive bladder.
Allergan, and business partners Endo Pharmaceuticals Solutions Inc. (ENDP) and Supernus Pharmaceuticals Inc. (SUPN), contend in a federal court complaint that Watson plans to market a generic version of Sanctura before the 2008 patent expires in 2025.
“Plaintiffs will be irreparably harmed by Watson Pharmaceuticals’ infringing activities” unless stopped by a judge, according to court papers filed yesterday in Wilmington, Delaware.
Irvine, California-based Allergan, with $4.4 billion in total sales last year, and Endo of Chadds Ford, Pennsylvania, with $1.26 billion in 2008 sales, co-market Sanctura in the U.S., according to the lawsuit. Rockville, Maryland-based Supernus, the closely held patent owner, bought out Shire Laboratories in 2005.
Besides an injunction against generic sales, Allergan and its partners seek unspecified damages and a declaration that the patent is infringed.
Patty Eisenhaur, a Watson spokeswoman, didn’t immediately return a call seeking comment on the lawsuit.
Corona, California-based Watson, with $2.53 billion in sales last year, fell 2 cents to $33.50 at 4:29 p.m. in New York Stock Exchange composite trading.
Allergan rose 6 cents to $45.96 on the NYSE. Endo fell 13 cents to $17.64 in Nasdaq Stock Market trading.
The case is Allergan Inc. v. Watson Pharmaceuticals Inc. (WPI), 09CV511, U.S. District Court, District of Delaware (Wilmington).
