Bausch Health Files Lawsuit Against Sandoz For Infringement Of Patents Protecting XIFAXAN® 550 mg Tablets


BRIDGEWATER, N.J., Oct. 1, 2019 /PRNewswire/ -- Bausch Health Companies Inc. (TSX:BHC) ("Bausch Health" or the "Company") along with its wholly owned subsidiary, Salix Pharmaceuticals ("Salix"), which is one of the largest specialty pharmaceutical companies in the world committed to the prevention and treatment of gastrointestinal diseases, together with Salix's licensor Alfasigma SpA (collectively the "Salix Parties"), today announced that the Company has filed a lawsuit against Sandoz Inc., a Novartis division, alleging patent infringement of 14 patents by Sandoz's filing of its Abbreviated New Drug Application (ANDA) for XIFAXAN® (rifaximin) 550 mg tablets.

Bausch Health remains confident in the strength of the XIFAXAN patents and will continue to vigorously defend its intellectual property. XIFAXAN is protected by 22 patents covering the composition of matter and the use of XIFAXAN listed in the U.S. Food and Drug Administration's (FDA) Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book.

In September 2018, Bausch Health agreed to resolve the outstanding intellectual property litigation with Actavis Laboratories FL, Inc. ("Actavis"), regarding XIFAXAN 550 mg tablets. Under the terms of the agreement, the Salix Parties will grant Actavis a non-exclusive license effective Jan. 1, 20281 to the Salix Parties' intellectual property relating to XIFAXAN 550 mg tablets in the United States.
