U.S. District Court Upholds Final Judgment for XIFAXAN® 550 mg That Prevents FDA Approval of Norwich’s Abbreviated New Drug Application Until 2029

May 17, 2023

LAVAL, Quebec, May 17, 2023 – Bausch Health Companies Inc. (NYSE/TSX: BHC), and its gastroenterology business Salix Pharmaceuticals, today announced that the U.S. District Court of Delaware in the matter of Salix Pharmaceuticals, LTD et al v. Norwich Pharmaceuticals, Inc., has denied Norwich Pharmaceuticals’ motion to modify the Court’s final judgment that prevents the U.S. Food and Drug Administration (FDA) from approving Norwich’s abbreviated new drug application (ANDA) for XIFAXAN® (rifaximin) 550 mg before Oct. 2, 2029. As a result of this decision, Norwich’s ANDA cannot be approved until Oct. 2, 2029.

“This decision is important for patients who continue to depend on a proven and highly effective drug to treat gastro-intestinal disorders,” Thomas J. Appio, Chief Executive Officer stated. “It is our long- standing position that the XIFAXAN patent claims are valid and infringed by Norwich’s ANDA. We will continue to advocate for the safety of patients who have benefited from the continued access to XIFAXAN, and we look ahead to the appeal process.”

To date, Norwich has not received tentative or final approval of its ANDA from the FDA.
