Sulbactam/durlobactam (XACDURO®), is a co-packaged antibacterial product that has been developed by Entasis Therapeutics Inc. for the treatment of infections caused by Acinetobacter baumannii-calcoaceticus complex (ABC). Coadministration of durlobactam (a β-lactamase inhibitor with potent activity against a broad range of serine β-lactamases) with sulbactam (an established class A β-lactamase inhibitor with antibacterial activity against A. baumannii) prevents sulbactam degradation by ABC-produced β-lactamases. In May 2023, sulbactam/durlobactam was approved in the USA for use in patients 18 years of age and older for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of ABC. This article summarizes the milestones in the development of sulbactam/durlobactam leading to this first approval for the treatment of infections caused by ABC.
