Study Summary

The main objective of this study is to compare the median exposures at pharmacokinetic equilibrium of the two modalities of administration: 4-hours infusion of ceftolozane-tazobactam at a dosage of 2 gram three times a day vs 1-hour infusion of 2 gram three times a day.

Study Description

Intensive care unit patients with ventilator associated-pneumonia often develop severe and rapidly life threatening Gram-negative Bacillus infections. Moreover, they present pathophysiological disturbances responsible for major pharmacokinetic changes (volume of distribution and glomerular filtration) which may lead to drugs under-exposure. Any delay in management or inadequate antibiotic therapy can have serious consequences in terms of prognosis. The association ceftolozane-tazobactam is an alternative to carbapenems in documented infections. Ceftolozane is a new cephalosporin, marketed, in combination with tazobactam (beta-lactamase inhibitor) under the name ZERBAXA®. ZERBAXA® is active on Gram-negative Bacillus, including Pseudomonas aeruginosa.

This is a prospective, randomized, open pharmacokinetic/pharmacodynamic study that compares two modalities of administration of a novel antibiotic, ZERBAXA® ceftolozane-tazobactam, by 4-hours infusion at the dosage of 2 gram three times a day vs. 1-hour infusion at the dosage of 2 g three times a day, among patients with ventilator associated-pneumonia to Pseudomonas aeruginosa.

The patient will be randomized either in the 4-hours or in the 1-hour infusion group. Follow up visits are daily for any intensive care patient. Those provided for biomedical research are carried out during the treatment period, at Day 15 and Day 28. For the pharmacokinetic study, 7 blood samples will be collected from 24 hours to 48 hours after the first ZERBAXA® administration.
