Shionogi to Present New Data at IDWeek 2019

OSAKA, Japan & FLORHAM PARK, N.J.–(BUSINESS WIRE)–OSAKA, Japan & FLORHAM PARK, N.J.–(BUSINESS WIRE)–Shionogi & Co., Ltd. (hereafter “Shionogi”) today announced that the company will deliver 20 data presentations for Shionogi compounds, including a late-breaker oral presentation of cefiderocol Phase III APEKS-NP trial results, at IDWeek™, October 2-6, 2019, in Washington, D.C.

Cefiderocol is a siderophore cephalosporin with a novel mechanism for penetrating the outer cell membrane of Gram-negative pathogens including multidrug-resistant strains. At IDWeek, Shionogi will share findings from the APEKS-NP trial evaluating the investigational antibiotic cefiderocol in adults with hospital-acquired bacterial pneumonia, ventilator-associated bacterial pneumonia, or healthcare-associated bacterial pneumonia caused by Gram-negative pathogens. Additionally, Shionogi will share findings from other studies investigating cefiderocol, and the prevalence and characterization of carbapenem-resistant bacterial infections.

The company will also present data for XOFLUZA (baloxavir marboxil), a first-in-class, one-dose oral medicine for the treatment of acute uncomplicated influenza in patients 12 years of age and older who have been symptomatic for no more than 48 hours.

“This is the first release of data from the Phase III APEKS-NP trial. The results strengthen our belief that cefiderocol has the potential to make a meaningful difference for patients fighting life-threatening Gram-negative infections,” said Dr. Tsutae “Den” Nagata, Chief Medical Officer, Shionogi.

Presentations will include data from company-sponsored or investigator-initiated investigational studies. The details for the presentations are as follows:

About Cefiderocol–An Investigational Antibiotic Agent
Cefiderocol is a parenteral siderophore cephalosporin with a novel mechanism for penetrating the outer cell membrane of Gram-negative pathogens including multidrug-resistant strains. Cefiderocol binds to ferric iron and is actively transported into bacterial cells through the outer membrane via the bacterial iron transporters, which function to incorporate this essential nutrient for bacteria.1 In addition, cefiderocol can also enter cells by passive diffusion through porin channels and is stable against all known classes of beta-lactamases, including both the metallo- and serine-beta-lactamases.2 These mechanisms allow cefiderocol to achieve higher concentrations in the periplasmic space where it can bind to receptors and inhibit cell wall synthesis in the bacterial cells.3 Data from multinational surveillance studies for cefiderocol demonstrated potent in vitro activity against a wide spectrum of Gram-negative pathogens including carbapenem-resistant Acinetobacter baumannii (A. baumannii), Pseudomonas aeruginosa (P. aeruginosa), Enterobacteriaceae, and Stenotrophomonas maltophilia (S. maltophilia).4 Cefiderocol has poor in vitro activity against Gram-positive or anaerobic bacteria. The clinical significance of in vitro data is unknown.

Shionogi submitted a New Drug Application to the U.S. Food and Drug Administration (FDA). Cefiderocol was designated as a Qualified Infectious Disease Product (QIDP) by the FDA with the assigned action date of November 14, 2019 under the Prescription Drug User-Fee Act (PDUFA). Additionally, Shionogi also submitted a marketing authorization application of cefiderocol to the European Medicines Agency and it was accepted in March 2019.5

About Gram-negative Infections
The increasing resistance of many infections caused by Gram-negative bacteria to existing therapies, including carbapenem-resistant Enterobacteriaceae and non-fermenting species such as P. aeruginosa, A. baumannii, and S. maltophilia, means there is a critical need for new, effective therapies.4, 6-9 There are an increasing number of Gram-negative pathogens resistant to multiple antibiotics, making them difficult to treat and resulting in high mortality rates.10 In the U.S., at least two million people are infected with antibiotic-resistant bacteria, and at least 23,000 people die as a result each year.11 In the EU, about 25,000 patients die from an infection with the selected multidrug-resistant bacteria.12 The World Health Organization and the Centers for Disease Control and Prevention have identified carbapenem-resistant strains of Enterobacteriaceae, P. aeruginosa, and A.baumannii as the top priority in the research and development of new antibiotics.6,11

About XOFLUZA™ (baloxavir marboxil)
XOFLUZA, discovered by Shionogi, has a novel mechanism of action that inhibits cap-dependent endonuclease in the polymerase acidic (PA) protein (in the United States Prescribing Information, this enzyme is stated as polymerase acidic endonuclease), an enzyme essential for viral replication. The regimen for XOFLUZA is one-oral dose to treat uncomplicated influenza, which is different from all currently available antiviral treatments. In non-clinical studies, XOFLUZA demonstrated an antiviral effect against a wide range of influenza viruses including oseltamivir-resistant strains and avian strains (H7N9, H5N1).13-14 XOFLUZA was approved and is now available in Japan for the treatment of influenza Types A and B in adults and paediatric patients.15 In addition, XOFLUZA was approved in Taiwan on August 28, 2019, for the treatment of acute influenza Types A and B in patients aged 12 years of age and older.16

Shionogi and the Roche Group, which includes Genentech in the U.S., have a license and collaboration agreement to further develop and commercialize XOFLUZA globally. Under the terms of this agreement, Roche Group holds worldwide rights to XOFLUZA excluding Japan and Taiwan, which will be retained exclusively by Shionogi & Co., Ltd. XOFLUZA is currently available across the U.S. for the treatment of acute, uncomplicated influenza in people 12 years of age or older.17 The U.S. Food and Drug Administration (FDA) has accepted a supplemental NDA for XOFLUZA for the treatment of influenza in individuals at high-risk for influenza-related complications 12 years and older. The PDUFA date for an FDA decision is November 4, 2019.18 For more information, please refer to the XOFLUZA website.

Roche is now conducting a Phase III development program including children under the age of one year, and severely ill, hospitalized patients, as well as to assess the potential to reduce transmission of influenza from an infected person to healthy people. Shionogi is assessing the potential of XOFLUZA as a post-exposure prophylaxis treatment to prevent the spread of influenza in adults and children, and positive results were obtained in the Phase III study.19

About Influenza
Seasonal and pandemic influenza remain a major public health concern, and novel influenza drugs that will offer significant improvement over current therapy are urgently needed. Globally, seasonal epidemics result in three-to-five million cases of severe disease, millions of hospitalizations and up to 650,000 deaths every year.20-24
