Meropenem-vaborbactam for the treatment of complicated urinary tract infections including acute pyelonephritis

ABSTRACT

Introduction: Meropenem-vaborbactam is a new beta-lactam/beta-lactamase inhibitor combination that combines a carbapenem antibiotic with a first-in-class, boronic acid pharmacophore, serine beta-lactamase inhibitor which has potent inhibitory activity against class A carbapenemases, especially Klebsiella pneumoniae carbapenemases (KPC), in addition to other class A and class C beta-lactamases. The US Food and Drug Administration has recently approved meropenem-vaborbactam for the treatment of adult patients with complicated urinary tract infections including acute pyelonephritis.

Areas covered: A PubMed search was performed to gather the most current and relevant articles regarding meropenem-vaborbactam. In this review the authors discuss the chemistry, mechanism of action, pharmacokinetics, pharmacodynamics, antimicrobial spectrum, and efficacy and safety of meropenem-vaborbactam for the treatment of complicated urinary tract infections including acute pyelonephritis

Expert opinion: Although meropenem-vaborbactam is approved for treatment for complicated urinary tract infections including acute pyelonephritis, it is unlikely, at this point, to be utilized widely beyond cases that are caused by KPC-producing Enterobacteriaceae. It may also be a potential treatment option for complicated urinary tract infections caused by KPC-producing Enterobacteriaceae that are resistant to ceftazidime-avibactam. Long-term safety data with this novel beta-lactamase inhibitor is still needed although early data suggests that it will be safe and well tolerated.
