The Salix Parties will grant Sun a non-exclusive license effective Jan. 1, 2028 to its intellectual property relating to XIFAXAN 200 mg and 550 mg tablets in the United States .

In April 2019 , Bausch Health filed a lawsuit against Sun following receipt of a Notice of Paragraph IV Certification relating to XIFXAN 200 mg tablets. Additionally, Bausch Health received a Notice of Paragraph IV Certification from Sun relating to XIFAXAN 550 mg tablets on Aug. 10, 2020 .

"Resolving these matters with Sun is another testament to the strength of the XIFAXAN intellectual property," said Joseph C. Papa , chairman and CEO, Bausch Health . "We will continue to defend our intellectual property protecting XIFAXAN, and we will continue to invest in the research and development of new indications and formulations for rifaximin that can potentially benefit more patients."

"Alfasigma is satisfied with the resolution," said Pier Vincenzo Colli, CEO of Alfasigma. "In the interest of patients and customers, our company is committed to using any efforts to protect its intellectual property covering XIFAXAN."

Sun acknowledges the validity of the licensed patents with respect to the two XIFAXAN products. Final patent expiry on XIFAXAN 200 mg and 550 mg tablets are July and October 2029 , respectively.

Under the terms of the agreement, beginning Jan. 1, 2028 ¹ (or earlier under certain circumstances), Sun will have the right to market royalty-free generic versions of XIFAXAN 200 mg and  550 mg tablets, should it receive approval from the U.S. Food and Drug Administration (FDA) on its Abbreviated New Drug Application.

Litigation between the parties related to XIFAXAN will be dismissed, and all intellectual Property protecting XIFAXAN remains intact. Bausch Health and Alfasigma remain confident in the strength of the XIFAXAN patents, and they will continue to vigorously defend their intellectual property. XIFAXAN 200 mg and 550 mg tablets are collectively protected by 26 patents covering the composition of matter and the use of XIFAXAN listed in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book.
