Shionogi To Highlight Research On Cefiderocol (S-649266), A Siderophore Cephalosporin, And S-033188, A Cap-Dependent Endonuclease Inhibitor For Treatment Of Influenza, At IDWeek 2017

OSAKA, Japan and FLORHAM PARK, N.J., Sept. 28, 2017 /PRNewswire/ -- Shionogi & Co., Ltd. (hereafter "Shionogi") today announced it will share the latest data on cefiderocol (S-649266), an investigational siderophore cephalosporin with a novel mechanism of cell entry in late stage development with activity against a broad range of Gram-negative pathogens, including those highly resistant to currently available agents such as colistin, and carbapenem-resistant strains of Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterobacteriaceae (CRE) and Stenotrophomonas maltophilia, and S-033188, an investigational cap-dependent endonuclease inhibitor for the treatment of influenza at IDWeek(TM) 2017, in San Diego, October 4 - 8, 2017.

Highlights of cefiderocol presentations include clinical trial results, as well as supportive in vitro data. S-033188 presentations will showcase both clinical and non-clinical data.

Below is an overview of the oral and poster presentations featuring cefiderocol and S-033188 at IDWeek 2017:

About cefiderocol--an investigational antibiotic agent
Cefiderocol is a siderophore cephalosporin with a novel mechanism for efficiently penetrating the outer cell membrane of Gram-negative pathogens. 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) This mechanism allows cefiderocol to achieve higher concentrations in the periplasmic space where it can then bind to receptors and inhibit cell wall synthesis in the bacterial cells.(2) 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-carbapenemases.(3) Data from global surveillance studies for cefiderocol demonstrated potent in vitro activity against a wide spectrum of Gram-negative pathogens including carbapenem-resistant A. baumannii, P. aeruginosa, Enterobacteriaceae, and S. maltophilia.(4 )Cefiderocol has poor in vitro activity against Gram-positive or anaerobic bacteria.

About S-033188--an investigational product
S-033188 is a cap-dependent endonuclease inhibitor with a novel mechanism of action being studied for the treatment of influenza. S-033188 is an investigational product being developed for one-time dosing, and has the potential to deliver higher potency antiviral effects than existing marketed anti-influenza products. Development and commercialization are in collaboration with F. Hoffmann-La Roche Ltd.

About Influenza
Epidemic and pandemic influenza remain a major public health concern, and novel influenza drugs that will offer significant improvement over current therapy are urgently needed. Worldwide, annual influenza epidemics are estimated to result in 3 to 5 million cases of severe illness, and about 250,000 to 500,000 deaths.(5) In general, those at highest risk of influenza-associated complications include children under 2 years of age, adults over 65 years of age, pregnant women, and people of any age with certain medical conditions, including chronic heart, lung, metabolic diseases (such as diabetes) and weakened immune systems.
