Shionogi Continues Global Commitment to Advances in Infectious Disease with Key Data Presentations from Its Expanding Product Portfolio at IDWeek 2024

Company Continues Innovating After More than 60 Years in Infectious Disease and Plans for its Strongest IDWeek Presence in History

Florham Park, NJ, September 4, 2024 - Shionogi Inc., the United States subsidiary of Shionogi & Co., Ltd., (Head Office: Osaka, Japan; Chief Executive Officer: Isao Teshirogi, Ph.D.) will have 22 scientific presentations across the company’s infectious disease portfolio at IDWeek 2024 (October 16-19, 2024) in Los Angeles, California.

Key among Shionogi’s 13 data presentations for Fetroja® (cefiderocol) will be a new real-world evidence study including approximately 1,000 patients treated with cefiderocol from across the U.S. and Europe. This trial, known as PROVE, is the largest study to evaluate cefiderocol use in hospitalized patients with serious Gram-negative infections, the majority of whom were resistant to carbapenem antibiotics.

Notably, Shionogi will have two oral presentations featuring nonclinical data evaluating cefiderocol activity against some of the most difficult-to-treat bacterial strains that were resistant to antibiotics, alone and in combination with xeruborbactam, an investigational beta-lactamase inhibitor that became part of the Shionogi pipeline with the acquisition of Qpex Biopharma, Inc. (hereafter “Qpex”) by Shionogi Inc. in 2023.

“Here in the U.S., a core focus of our work includes continuing to evaluate real-world outcomes associated with the use of our antibiotic for the treatment of certain Gram-negative infections and ensuring we’re meeting the educational and practical needs of our customers and their patients,” said Nate McCutcheon, President and Chief Executive Officer, Shionogi Inc. “We’re proud to make this important medication available and we also recognize that ongoing innovation is critical in infectious disease. That’s why we recently announced plans to expand our global infectious disease and antimicrobial research operations in the U.S. through Qpex with the establishment of our first U.S.-based discovery laboratory in San Diego.”

Shionogi is honored to announce that Michael N. Dudley, PharmD, President and CEO of Qpex will deliver the keynote address at the Society of Infectious Diseases Pharmacists (SIDP) Annual Meeting, taking place in conjunction with IDWeek.

In addition to numerous scientific presentations at IDWeek, Shionogi will once again enable the infectious disease community to join the fight and take a stand against the global public health threat of antimicrobial resistance (AMR) with a new version of its award-winning AMR Warrior experience. All visitors to Shionogi’s Booth #322 will have the opportunity to create their own AMR Warrior and use the image to spread awareness amongst their own networks and communities.

Shionogi’s presence at IDWeek will also include a sponsored Learning Lounge on Friday, October 18, at 10:15 AM PT, featuring Thomas Lodise, PharmD, PhD, Professor at the Albany College of Pharmacy and Health Sciences, entitled “Fetroja® (cefiderocol): An Overview of In Vitro, Clinical, and Real-world Data.”
