Shionogi to Present New Data at European Congress of Clinical Microbiology and Infectious Diseases 2019

OSAKA, Japan, AMSTERDAM, & FLORHAM PARK, N.J.–(BUSINESS WIRE)–Shionogi & Co., Ltd. (Head Office: Osaka, Japan; President and CEO: Isao
Teshirogi, Ph.D.) and Shionogi B.V. and Shionogi Inc., the European and
the U.S. subsidiaries of Shionogi & Co., Ltd respectively, (hereafter
“Shionogi”) today announced 12 data presentations taking place at the
European Congress of Clinical Microbiology and Infectious Diseases
(ECCMID), being held April 13-16, 2019 in Amsterdam.

Eight posters will be presented on cefiderocol, a late-stage
investigational, novel siderophore cephalosporin. Cefiderocol has broad
Gram-negative antimicrobial activity against all the critical
Gram-negative pathogens the World Health Organization has identified as
being the highest priority for finding new treatment options.*

Data for XOFLUZA (baloxavir marboxil), a first-in-class,
single-dose oral medicine for the treatment of influenza, will be
presented in two oral presentations and two posters.

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

“We look forward to sharing findings from several large-scale
surveillance studies conducted in Europe and North America, in which
cefiderocol demonstrated potent in vitro activity against
problematic Gram-negative bacteria. We believe these data further
support the clinical profile of cefiderocol in treating serious and
life-threatening infections,” said Dr. Tsutae Den Nagata, Chief Medical
Officer, Shionogi. “In addition, the XOFLUZA data to be presented add to
the growing body of evidence of the drug’s robust efficacy and utility
against influenza, which remains a global public health concern.”

About Cefiderocol

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-β-lactamases.2
These mechanism allows 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 global
surveillance studies for cefiderocol demonstrated potent in vitro 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.

Two Phase III studies are ongoing in patients with HAP/VAP/HCAP†
(APEKS-NP‡) and with carbapenem-resistant pathogens at various infection
sites (CREDIBLE-CR). Information is available at under
the identifiers NCT02714595 and NCT03032380, respectively.

About Gram-negative Infections

The availability of effective therapies against Gram-negative bacteria,
including carbapenem-resistant Enterobacteriaceae and non-fermenting
species such as P. aeruginosa, A. baumannii and S.
, is an important unmet medical need.4-8 There
are an increasing number of Gram-negative pathogens resistant to
multiple antibiotics, making them difficult to treat and resulting in
high mortality rates.9 In the U.S., at least 2 million people
are infected with antibiotic-resistant bacteria, and at least 23,000
people die as a result each year.10 In the EU, about 25 000
patients die from an infection with the selected multidrug-resistant
bacteria.11 The World Health Organization have identified
carbapenem-resistant strains of Enterobacteriaceae, P. aeruginosa
and A.baumannii as the top priority in the research and
development of new antibiotics.5

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 a single 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).12-14
XOFLUZA was approved and is now available in Japan for the treatment of
influenza Types A and B in adults and paediatric patients.15
Shionogi submitted a NDA for XOFLUZA in Taiwan on June 29, 2018, for the
treatment of influenza in patients 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
New Drug Application for XOFLUZA for the treatment of influenza in
individuals at high-risk for influenza-related complications 12 years
and older. The Prescription Drug User Fee Act (PDUFA) date for an FDA
decision is November 4, 2019. For more information, please refer to the XOFLUZA

Roche is now conducting a Phase III development program including
paediatric populations, and hospitalised patients with severe influenza
and will further assess the potential to reduce transmission in
otherwise healthy patients. Shionogi is conducting a post-exposure Phase
III prophylaxis study in Japan in the 2018/2019 north hemisphere flu

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, annual epidemics result
in three-to-five million cases of severe disease, millions of
hospitalizations and up to 650,000 deaths worldwide.18-22
