Statement Regarding Xifaxan Intellectual Property Litigation

LAVAL, Quebec, May 17, 2017 -- (Healthcare Sales & Marketing Network) -- Salix Pharmaceuticals, Inc. and parent Valeant Pharmaceuticals International, Inc. (NYSE: VRX and TSX: VRX) ("Valeant") and Actavis Laboratories, Inc., at Actavis' request, have agreed to stay outstanding litigation and extend the 30-month stay regarding Actavis' Abbreviated New Drug application (ANDA) for a generic version of XIFAXAN (rifaximin) 550 mg tablets.

Valeant initiated the litigation against Actavis on March 23, 2016. Additionally, Valeant filed a Citizen Petition with the U.S. Food and Drug Administration (FDA) on Oct. 17, 2016, requesting changes to previously recommended standards for approval of generic versions of XIFAXAN. On March 16, 2017, the FDA answered the Citizen Petition and issued its revised draft guidance regarding the recommended standards for approval of ANDAs for generic versions of XIFAXAN.

Legal action is stayed through April 30, 2018 and cannot be lifted prior to Oct. 31, 2017. All currently scheduled litigation activities, including the January 2018 trial date, have been indefinitely removed from the Court docket.

The parties agree and the Court ordered that Actavis' 30-month regulatory stay shall be extended from Aug. 12, 2018 until no earlier than Feb. 12, 2019 and could be longer if the litigation stay lasts for more than 6 months.

Valeant remains confident in the strength of the XIFAXAN patents and will defend its intellectual property vigorously.
