NEW YORK--(EON: Enhanced Online News)--Pfizer Inc. (NYSE:PFE) today announced that it has completed the acquisition of the development and commercialization rights to AstraZeneca’s late-stage small molecule anti-infective business, primarily outside the United States. The agreement includes the commercialization and development rights to the newly approved EU drug Zavicefta™ (ceftazidime-avibactam), the marketed agents Merrem™/Meronem™ (meropenem) and Zinforo™ (ceftaroline fosamil), and the clinical development assets aztreonam-avibactam (ATM-AVI) and CXL. Zavicefta specifically addresses certain multi-drug resistant Gram-negative infections, including those resistant to carbapenem antibiotics, one of the most significant unmet medical needs in bacterial infections treated with hospital anti-infectives.
“Forward-Looking Information and Factors That May Affect Future Results”
“The addition of AstraZeneca’s complementary small molecule anti-infectives portfolio enhances our global expertise and offerings in an increasingly important area of therapeutics that addresses the public health needs of patients and healthcare professionals. Additionally this acquisition is an example of how we are focusing our investments to drive sustainable revenue growth potential for our Essential Health business,” said John Young, group president, Pfizer Essential Health.
About the acquired assets
Zinforo was launched in October 2012 and is an
intravenous cephalosporin antibiotic intended for use as a
monotherapy in the treatment of adult patients with complicated skin
and soft tissue infections (cSSTI) or community-acquired pneumonia
(CAP). Zinforo is bactericidal and works by binding to and
inhibiting penicillin-binding proteins (PBPs). Zinforo has
been designed with a specific and novel mode of action which
contributes to its bactericidal activity against the common
causative pathogens of cSSTI, and shows a high affinity for
particular PBPs in MRSA in cSSTI and Streptococcus pneumoniae
in CAP. Zinforo has now been approved in 52 markets and
launched in 32 markets.
Pfizer holds the global rights to commercialize Zinforo, with the exception of North America (U.S. and Canada) and Japan, where the rights are held by Allergan Pharmaceutical Industries Limited and Takeda Pharmaceutical Company Limited, respectively.
Zavicefta (ceftazidime-avibactam) is a combination antibiotic
that has been developed to treat serious Gram-negative bacterial
infections. It consists of a combination of avibactam and
ceftazidime – a third generation antipseudomonal cephalosporin with
a well-established efficacy and safety profile. Avibactam is a
first-in-class broad-spectrum β-lactamase inhibitor, which protects
ceftazidime against degradation by Class A, C and some D,
β-lactamases. The addition of avibactam to ceftazidime protects
ceftazidime from breakdown by β-lactamases. Zavicefta offers
a differentiated profile versus existing treatment options in
serious Gram-negative infections through its coverage of a broad
range of species of Enterobacteriaceae including those that
produce extended-spectrum beta-lactamase and Klebsiella pneumonia
carbapenemase, together with activity against difficult-to-treat P.
Pfizer holds the global rights to commercialize Zavicefta, with the exception of North America (U.S. and Canada), where the rights are held by Allergan.
Merrem/Meronem is a carbapenem anti-bacterial used for the
treatment of serious infections in hospitalised patients. Meronem
is a broad spectrum agent indicated for the treatment of a wide
variety of serious bacterial infections in adults and children,
including pneumonia, community acquired pneumonia and nosocomial
pneumonia; broncho-pulmonary infections in cystic fibrosis;
complicated urinary tract infections; complicated intra-abdominal
infections; intra- and post-partum infections; complicated skin and
soft tissue infections; and acute bacterial meningitis in adults and
children over 3 months of age. In the U.S., Merrem is
indicated as single agent therapy for the treatment of
intra-abdominal infections and bacterial meningitis when caused by
susceptible strains of the designated microorganisms in adult and
Pfizer holds the global rights to commercialize Merrem, with the exception of Japan, China, Taiwan, Korea, Thailand, the Philippines, Malaysia, Singapore, Vietnam and Hong Kong where the rights are held by Sumitomo Dainippon Pharma Co., Ltd.
ATM-AVI is a bactericidal, injectable combination of aztreonam (ATM)
and a β-lactamase inhibitor, avibactam (AVI, NXL104), which is in
development for the treatment of life-threatening Gram-negative
bacterial infections caused by multi-drug resistant (MDR) strains,
including infections caused by metallo-beta-lactamase
(MBL)-producing pathogens. ATM-AVI has the potential to be a
replacement for, or alternative to, existing antibacterial agents,
including colistin and tigecycline. ATM-AVI has completed its Phase
I studies and is currently in Phase II development.
Pfizer holds the global rights to commercialize ATM-AVI, with the exception of North America (U.S. and Canada), where the rights are held by Allergan.
CXL is a novel, injectable bactericidal β-lactam/β-lactamase
inhibitor combination of ceftaroline fosamil (marketed as Zinforo
in AstraZeneca markets), a next-generation cephalosporin with
activity against multidrug-resistant Gram-positive and common
enteric Gram-negative pathogens, and avibactam (AVI, NXL104), a
potent β-lactamase inhibitor that inhibits Ambler Class A (including
ESBL producers and KPC carbapenemases), Class C (Amp C) β-lactamase
enzymes, and some Class D β-lactamase enzymes.
Pfizer holds the global rights to commercialize CXL, with the exception of North America (U.S. and Canada), where the rights are held by Allergan.
