Shionogi to Present Cefiderocol and COT-143 Data at American Society for Microbiology Microbe 2019 Meeting
Shionogi & Co., Ltd. (hereafter "Shionogi") today announced there will be one oral presentation and 17 poster presentations featuring two of the company's investigational compounds at the American Society for Microbiology (ASM) Microbe meeting, being held June 20?24, 2019 in San Francisco. Sixteen poster presentations are on cefiderocol, a late-stage investigational, novel siderophore cephalosporin, and one is on COT-143, a humanized monoclonal antibody.
"Cefiderocol has a unique mechanism of cell entry and is able to overcome the three major mechanisms of carbapenem-resistance of Gram-negative pathogens. The totality of cefiderocol data to be presented at ASM Microbe adds to the growing body of evidence of its potential activity against some of the world's deadliest pathogens and we look forward to sharing these findings with the scientific community," said Dr. Tsutae Den Nagata, Chief Medical Officer, Shionogi.
In addition, Shionogi will also present a poster on COT-143, an investigational humanized monoclonal antibody demonstrating anti-virulence activity targeting the PcrV protein of Pseudomonas aeruginosa.
Presentations will include data on these Shionogi agents 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 siderophore cephalosporin with a novel mechanism for penetrating the outer cell membrane of Gram-negative pathogens including multidrug-resistant strains. It has a unique ability to overcome all three major mechanisms of carbapenem resistance. 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, Pseudomonas aeruginosa, Enterobacteriaceae, and Stenotrophomonas maltophilia.4 Cefiderocol has poor in vitro activity against Gram-positive or anaerobic bacteria. The clinical significance of in vitro data is unknown.
Two ongoing Phase III studies?in patients with HAP/VAP/HCAP? (APEKS-NP?) and with carbapenem-resistant pathogens at various infection sites (CREDIBLE-CR) have recently completed enrollment. Information is available at www.clinicaltrials.gov under the identifiers NCT03032380 and NCT02714595, respectively. The company submitted a New Drug Application to the U.S. Food and Drug Administration in December 2018 and a marketing authorization application to the European Medicines Agency 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 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 COT-143?An Investigational Compound
COT-143 is a humanized monoclonal antibody that binds to the PcrV protein of P. aeruginosa. The PcrV protein is an essential component of the type III secretion system responsible for releasing harmful toxins and is related to the pathogenicity of P. aeruginosa. By using a variety of nonclinical in vitro and in vivo models, COT-143 has demonstrated the potential to reduce tissue and cellular damage by the toxins released by this system, leading to the treatment of infection caused by P. aeruginosa.
It is estimated that 51,000 healthcare-associated P. aeruginosa infections occur in the U.S. each year and the rates of antibiotic resistance are increasing worldwide.12-13 As resistance rises, there are limited options to treat or prevent P. aeruginosa infections. COT-143 is in early-stage development.
