FDA approves Zerbaxa to treat hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia

Merck Inc., announced that the FDA has approved Merck’s supplemental New Drug Application (sNDA) for the use of Zerbaxa (ceftolozane and tazobactam) for the treatment of patients 18 years and older with hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by the following susceptible Gram-negative microorganisms: Enterobacter cloacae, Escherichia coli, Haemophilus influenzae, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, and Serratia marcescens. The sNDA for Zerbaxa had previously been designated Priority Review status by the FDA. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Zerbaxa and other antibacterial drugs, Zerbaxa should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

Comment: This expanded use is based on results of the pivotal Phase III ASPECT-NP trial that compared Zerbaxa 3g (ceftolozane 2g and tazobactam 1g) intravenously every 8 hours to meropenem (1g intravenously every 8 hours) for 8 to 14 days for the treatment of adult patients with HABP/VABP.
