Cubist Pharmaceuticals Inc. recently announced that the FDA has accepted the company’s new drug application for its novel combination antibiotic ceftolozane/tazobactam with priority review.

Cubist is seeking FDA approval of the antibiotic for the treatment of complicated urinary tract infections and complicated intra-abdominal infections.

The new drug application is based on results from two phase 3 clinical trials of ceftolozane/tazobactam, which demonstrated activity against several gram-negative pathogens causing UTIs and intra-abdominal infections in adult patients. These included Pseudomonas aeruginosa, extended-spectrum beta-lactamase–producing Escherichia coli and Klebsiella pneumoniae.

Under the Generating Antibiotic Incentives Now (GAIN) Act, the FDA designated the antibiotic as a qualified infectious disease product (QIDP) in 2013, making it eligible for fast track status and priority review. QIDP status also gives Cubist a 5-year extension of product exclusivity if the drug is ultimately approved by the FDA.
