NEW YORK--(EON: Enhanced Online News)--Pfizer Inc. today announced that Zavicefta, a novel combination antibiotic for the treatment of patients with certain confirmed or suspected Gram-negative bacterial infections requiring hospitalization, is now available in the U.K. and Germany. Pfizer expects to launch Zavicefta in additional markets outside the U.S. throughout 2017 and 2018. Zavicefta was developed in response to the urgent medical need for new antibiotics for difficult-to-treat Gram-negative bacteria, many of which have become increasingly resistant to currently available antibiotics.
“priority pathogens which pose the greatest threat to human health.”
In June 2016, the European Medicines Agency (EMA) approved the marketing authorization for Zavicefta based on an extensive clinical trial program. Zavicefta is indicated for the treatment of adults with complicated intra-abdominal infection (cIAI), complicated urinary tract infection (cUTI) and Hospital-Acquired Pneumonia (HAP), including Ventilator Associated Pneumonia (VAP). Zavicefta is also indicated for the treatment of infections due to aerobic Gram-negative organisms in adult patients with limited treatment options. Zavicefta addresses Pseudomonas Aeruginosa and Enterobacteriaceae, two of three “critical” pathogens recently identified by the World Health Organization (WHO)1. In many markets, existing treatments do not consistently address these resistant pathogens adequately.
“Multidrug-resistant (MDR) infections are an increasing global threat. The availability of Zavicefta is a major step forward for physicians faced with the challenge of treating patients with known or suspected MDR infections,” said Dr. Matteo Bassetti, Chief of the Infectious Diseases Clinic at University of Udine in Italy.
“The launch of Zavicefta reaffirms Pfizer’s longstanding heritage and commitment to patients facing serious infectious diseases,” said Dr. Freda Lewis-Hall, Executive Vice President and Chief Medical Officer of Pfizer Inc. “We continue to search for solutions to one of humanity’s most pressing challenges—defeating the microbes that cause infection and misery.”
About Antimicrobial Resistance
The WHO characterizes antimicrobial resistance as one of the biggest threats to global health, that can affect anyone at any age in any country, threatening our ability to treat serious infections and provide standard medical procedures. Gram-negative bacteria, the cause of many healthcare-associated infections (HAIs), have become increasingly resistant to many available antibiotic treatments. These infections are associated with increased patient mortality and cost of care. At present, approximately 700,000 deaths per year are attributed to antimicrobial resistance globally, with an increase to 10 million predicted by 2050 if no action is taken to address this issue. For example, according to the European Centre for Disease Prevention and Control (ECDC) Gram-negative bacteria are responsible for approximately two-thirds of the estimated 25,000 deaths that result from antimicrobial resistance annually in Europe.

Zavicefta (ceftazidime-avibactam) is a fixed-dose combination antibacterial that was 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.Avibactam does not inhibit class B enzymes (metallo-β-lactamases) and is not able to inhibit many of the class D enzymes.
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.
Important Zavicefta Safety Information
In clinical studies, ceftazidime-avibactam was proven to be as effective as current carbapenem standards of care in the treatment of serious aerobic Gram-negative infections, including in patients with infections caused by ceftazidime-resistant bacteria. The most common adverse events occurring in 5% or more of patients (n=2024 from seven Phase 2 and 3 clinical trials) treated with ceftazidime-avibactam included: the presence of antibodies that cause red blood cells to die early (positive Coombs direct test), nausea and diarrhea. Nausea and diarrhea were usually mild or moderate in intensity.

NOTES TO EDITORS
About Pfizer’s Commitment to AMR
Today, Pfizer is the leading global provider of anti-infective medicines in the industry, offering patients access to a diverse portfolio of more than 80 products. Pfizer recognizes the serious public health threat associated with Antimicrobial Resistance (AMR) and has taken significant steps to address this issue. In early 2016, Pfizer was a signatory of the Declaration on Combating Antimicrobial Resistance (AMR), a global call-to-action drafted and signed by more than 100 companies and 13 trade associations encouraging greater industry and government collaboration to address the issue of antimicrobial resistance. As a follow-up to the AMR Declaration, Pfizer and 13 industry partners unveiled the “Industry Roadmap to Combat Antimicrobial Resistance,” a comprehensive plan of action, that lays out four key commitments we pledge to deliver by 2020.
