Cubist Announces EMA Acceptance of Ceftolozane/Tazobactam Marketing Authorization Application for Review 

LEXINGTON, Mass., Aug 22, 2014 (BUSINESS WIRE) -- Cubist Pharmaceuticals, Inc. CBST, +0.19% today announced that the European Medicines Agency (EMA) has accepted for review the Company's Marketing Authorization Application (MAA) for its investigational antibiotic ceftolozane/tazobactam. Cubist is seeking approval of ceftolozane/tazobactam for the treatment of complicated urinary tract Infections and complicated intra-abdominal infections, with a decision from the European Commission (EC) expected during the second half of 2015.

The MAA submission is based on positive data from two pivotal Phase 3 clinical trials of ceftolozane/tazobactam in complicated urinary tract infections and complicated intra-abdominal infections. These studies met both the EMA and U.S. Food and Drug Administration (FDA) specified primary endpoints. Results of the secondary analyses were consistent with and supportive of the primary outcomes. In the clinical trials, ceftolozane/tazobactam demonstrated activity against problematic Gram-negative bacteria, including Pseudomonas aeruginosa and extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) and Klebsiella pneumoniae in patients with complicated infections.

"We are pleased to receive MAA acceptance for ceftolozane/tazobactam and look forward to working with the EMA on this important review," said Steven Gilman, Ph.D., Executive Vice President of Research and Development and Chief Scientific Officer of Cubist. "As we continue to expand globally, this advancement further positions Cubist to respond to growing health threats and reinforces our commitment to bring new antibiotics to patients worldwide facing serious infections, including those caused by Gram-negative bacteria."

Prior to the EMA acceptance of the MAA, the FDA accepted the Company's New Drug Application (NDA) for ceftolozane/tazobactam with Priority Review and assigned an action date of December 21, 2014.

About Ceftolozane/Tazobactam

Ceftolozane/tazobactam, an antibiotic candidate being developed to treat certain Gram-negative infections, consists of ceftolozane, a novel cephalosporin that has demonstrated potent in vitro activity against Pseudomonas aeruginosa, with tazobactam, a well-established beta-lactamase inhibitor. The addition of tazobactam broadens coverage to include most extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli), Klebsiella pneumoniae, and other Enterobacteriaceae. Ceftolozane/tazobactam is under review by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the potential treatment of complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI). Ceftolozane/tazobactam is also being developed for the potential treatment of hospital-acquired bacterial pneumonia (HABP)/ventilator-associated bacterial pneumonia (VABP).

About Gram-negative Bacteria

There has been a worldwide increase in the number of infections caused by Gram-negative bacteria. Highly adaptive pathogens that can develop resistance through several mechanisms, resistant Gram-negative bacteria are a serious global public health concern. Collectively, Escherichia coli(E. coli), Klebsiella pneumoniae (K. pneumoniae) and Pseudomonas aeruginosa (P. aeruginosa) account for 27% of all pathogens and 70% of all Gram-negative pathogens causing healthcare-associated infections (HAIs). Gram-negative bacteria are common causes of intra-abdominal infections (IAIs), urinary tract infections (UTIs), and nosocomial, or hospital-acquired, pneumonia, as well as bacteremia (bloodstream infections). E. coli is the most common cause of UTIs, and cases of UTI caused by extended-spectrum beta-lactamase (ESBL)-producing E. coli and K. pneumoniae, as well as P. aeruginosa, including drug-resistant strains, are increasing. ESBL-producing E. coli and K. pneumoniae are also frequently isolated in patients with complicated IAIs (cIAIs). Additionally, P. aeruginosa is the most common Gram-negative organism causing ventilator associated pneumonia and the second most common cause of catheter-associated UTIs. For more information reference a video on Gram-negative bacteria mechanisms of resistance.

About Cubist's Commitment to Antibiotic R&D

Cubist has a growing commitment to global public health through its leadership in the discovery, development, and commercialization of novel antibiotics to treat serious and potentially life-threatening infections caused by a broad range of increasingly drug-resistant bacteria. The Company hopes to deliver at least four new antibiotics in support of the Infectious Diseases Society of America (IDSA) goal of 10 new antibiotics by 2020. Cubist expects to invest approximately $400M USD in 2014 on antibacterial R&D and approximately 75% of its employee base is focused on the research, development, commercialization, and support of antibiotics.
