Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the ACTHEON Study is to evaluate the in vitro activity of ceftolozane-tazobactam, imipenem-relebactam and comparator agents (amoxicillin- clavulanate, piperacillin-tazobactam, ceftazidime, cefotaxime, cefepime, imipenem, meropenem, levofloxacin and amikacin; see list more details on page 7) against clinical isolates of P. aeruginosa and Enterobacterales prospectively collected from hematology and oncology patients with complicated intra-abdominal infections (cIAIs), complicated urinary infections (cUTIs), lower respiratory tract infections (LRTIs), and blood stream infections (BSIs) from 15 participating centers in Spain

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

P. aeruginosa isolates

All isolates will be sent to the Central Laboratory, where identification will be confirmed by MALDI-TOF and susceptibility testing against ceftolozane/tazobactam, imipenem- relebactam and comparative agents will be performed

Ceftolozane/tazobactam

Intervention Type DRUG

Minimum inhibitory concentrations (MICs) will be determined by the standard broth microdilution method (standard ISO method 20776-1:2006) using dry-form Sensititre panels (Thermo Fisher Scientific, Denmark) and will be interpreted according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) and the Clinical and Laboratory Standards Institute (CLSI) criteria
