Shionogi to Present Cefiderocol and COT-143 Data at American Society for Microbiology Microbe 2019 Meeting

OSAKA, Japan & FLORHAM PARK, N.J.–(BUSINESS WIRE)–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

Presentations will include data on these Shionogi agents from
company-sponsored or investigator-initiated investigational studies.

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
 activity against a wide spectrum of Gram-negative pathogens
including carbapenem-resistant Acinetobacter baumanniiPseudomonas
, Enterobacteriaceae, and Stenotrophomonas
.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 studiesin 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.
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.
