Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 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 g three times a day (tid) vs 1-hour infusion of 2 g tid.;Secondary Objective: Compare the average exposition obtained with the current recommendations for the 2 products: ceftolozane and tazobactam Estimate the percentage of patients correctly exposed to the 2 products: ceftolozane and tazobactam Determine if Ceftolozane-Tazobactam 4-hours infusion is linked to an improved bacteriological progression in broncho-alveolar liquid Determine if Ceftolozane-Tazobactam 4-hours infusion is linked to an improved clinical progression Determine alveolar concentration of Ceftolozane-Tazobactam from a sample of the alveolar fluid produced by bronchial fibroscopy between the 24th hour and the 48th hour;Primary end point(s): The primary endpoint is the time that the concentration spends above 5*MIC, expressed as a percentage of the time interval between two administrations. The T>5*MIC will be determined for each patient from the concentration profile measured over an 8-hour post-administration interval. Since protein binding is low (5*MIC will be calculated from the total concentrations. Our study will focus on only Pseudomonas aeruginosa PAVM with a critical MIC of 4 mg/l, T>5*MIC will then correspond to a residual serum concentration of 20 mg/l.;Timepoint(s) of evaluation of this end point: For the pharmacokinetic study, 7 blood samples will be collected from 24 hours to 48 hours after the first ZERBAXA® administration. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The percentage of patients with concentrations greater than 5*MIC over an 8-hour post administration interval Bactericidal rate obtained in vitro using the Hollow Fiber device. This rate is determined for broncho-alveolar concentrations estimated in patients with pneumonia acquired during ventilation, Bacteriological evaluation at the end of treatment and on day 15, based on actual bacteriological cure, presumed bacteriological cure, failure or bacterial superinfection to another germ. Percentage of patients recovering or failing at the end of the treatment period The number of days without artificial ventilation at D28, The duration of hospitalization, Survival at D28 The alveolar concentration of Ceftolozane-Tazobactam from a sample of the alveolar fluid produced by bronchial fibroscopy between the 24th hour and the 48th hour.;Timepoint(s) of evaluation of this end point: Depending on the secondary end points, the timepoints will occur: - Beetween the 24th hour and the 48th hour (after the beginning of the first infusion) - En fin de traitement (J7 à J10) - A J15 - A J28 | — |
