Activity of Meropenem-Vaborbactam against Pseudomonas aeruginosa and Acinetobacter baumannii in a Neutropenic Mouse Thigh Infection Model

We have evaluated the activity of meropenem-vaborbactam against clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii in a neutropenic mouse thigh infection model. Data show that meropenem-vaborbactam regimens equivalent to 3-h infusions every 8 h with 2 g meropenem and 2 g vaborbactam produced bacterial killing against strains with MICs of 2 to 16 mg/liter and suggests that this combination may have utility in the treatment of infections caused by P. aeruginosa and A. baumannii.
