The US Food and Drug Administration has approved Allergan's supplemental New Drug Application to expand the approved use of their cephalosporin / beta-lactamase inhibitor combo antibiotic, AVYCAZ (ceftazidime and avibactam), to include the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible Gram-negative microorganisms.

The US Food and Drug Administration (FDA) has approved Allergan's supplemental New Drug Application (sNDA) to expand the approved use of their cephalosporin / beta-lactamase inhibitor combo antibiotic, AVYCAZ (ceftazidime and avibactam), to include the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by the following susceptible Gram-negative microorganisms:

The antibiotic was originally approved to treat complicated intra-abdominal infections (cIAI) and complicated urinary tract infection (cUTI) in February 2015 in combination with metronidazole. It was approved in 2017 for complicated urinary tract infections (cUTI), including pyelonephritis, caused by designated susceptible Gram-negative bacteria, including certain Enterobacteriaceae and

. Subsequent testing on the efficacy of the antibiotic to treat other types of infections proved positive and led to the submission of the sNDA for HABP/VABP.

As

, studies have shown a “susceptibility rate of 94.6% and an MIC

of 8 μg/mL against

isolates for AVYCAZ, [as well as] susceptibility to 99.9% of

isolates overall (MIC

.5 μg/mL) and extended spectrum beta-lactamase-producing

pneumoniae isolates (MIC

2 μg/mL), 99.7% of all

isolates (MIC

1 μg/mL), and 92.0% of ertapenem-resistant

isolates (MIC

8 μg/mL).”
