Bausch Health Companies Inc. and Progenics Pharmaceuticals, announced that the U.S. District Court of New Jersey upheld the validity and determined Actavis’ infringement of a patent protecting RELISTOR (methylnaltrexone bromide) tablets, expiring March 2031.

Defendant, Actavis Laboratories FL, Inc., a subsidiary of Teva Pharmaceutical Industries Ltd, had challenged the validity of and had alleged non-infringement of Claims 2 and 5 of U.S. Patent No. 8,524,276, which protects the formulation of RELISTOR® tablets.

Bausch Health is not aware of any other ANDAs filed with the FDA seeking approval of a generic version of RELISTOR tablets, and will continue to vigorously defend its intellectual property in these and other claims.
