Vabomere (meropenem/vaborbactam)


Treatment of complicated urinary tract infections (cUTI), including pyelonephritis caused by the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae species complex in adults aged 18 yr or older.


Vaborbactam is a nonsuicidal beta-lactamase inhibitor that protects meropenem from degradation by certain serine beta-lactamases such as K pneumoniae carbapenemase (KPC). Meropenem inhibits bacterial cell wall synthesis.


4 g (meropenem [2g]/vaborbactam [2g]) IV q8hr for up to 14 days.

See full prescribing information for dose adjustment in patients with renal impairment.


Approval was based on data from a phase 3 multicenter, randomized, double-blind, double-dummy trial, TANGO-I (n=550), in adults with cUTI, including those with pyelonephritis. Data showed about 98.4% of patients treated with meropenem/vaborbactam IV exhibited cure/improvement in symptoms and a negative urine culture test, compared with 94.3% of patients treated with piperacillin/tazobactam.
