MedicalResearch.com: What is the background for this study?

Response: Complicated complicated urinary tract infections (cUTI), including acute pyelonephritis, are a major cause of hospital admissions, and are associated with significant morbidity and mortality and can be difficult to treat. While the most common pathogen is Escherichia coli, the more problematic pathogens are multidrug-resistant (MDR) gram-negative organisms including other Enterobacteriaceae species. The prevalence of cUTI due to MDR gram-negative bacteria has risen. In some instances, MDR gram-negative bacteria isolated from the urinary tract can cause bacteremia.

Vabomere was approved by the U.S. Food and Drug Administration (FDA) in August 2017 for the treatment of adult patients with cUTI, including pyelonephritis, caused by designated susceptible Enterobacteriaceae: Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae species complex.   Vabomere is a fixed-dose (2g/2g) combination product of a carbapenem and a β-lactamase inhibitor with potent in vitro activity against Klebsiella pneumoniae carbapenemase (KPC)-producing carbapenem-resistant Enterobacteriaceae (CRE), an important MDR organism associated with serious infections.

The Targeting Antibiotic Non-susceptible Gram-negative Organisms (TANGO I) trial was the pivotal Phase 3 study that compared the efficacy and safety of Vabomere to piperacillin-tazobactam in the treatment of patients with cUTI and acute pyelonephritis.
