- To demonstrate that colistin iv. is not inferior to meropenem in empiric treatment of VAP regarding the final point of primary efficacy: mortality in the 28 subsequent days and clinical healing in patients clinically evaluated.
- To compare the safety of treatment with colistin vs meropenem in VAP.
- To compare microbiological efficacy of treatment with colistin vs meropenem in VAP
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Ventilator-associated Bacterial Pneumonia | Drug: Colistin Drug: Meropenem | Phase 3 |
Study drugs: Patients will be randomized a 1:1 rate and open label fashion to two interventions: group 1: colistin loading dose followed by colistin infusion iv/8h or group 2: meropenem 2 g/iv/ 8 h. The overall treatment time will be a minimum of 8 days.
Follow-up visits will be performed at baseline, 72 h, 8 days, the end of treatment, and 28 days from recruitment ICU discharge, hospital discharge or death.

- Number of patients who die as a measure of efficacy [ Time Frame: 28 days ]Demostrate that colistin iv. is not inferior to meropenen in empiric treatment of VAP regarding the final point of primary efficacy: mortality in the 28 subsequent days
- Number of patients with clinical healing as a measure of efficacy [ Time Frame: 28 days ]Demostrate that colistin is not inferior to meropenem in empiric treatment of VAP regarding efficacy: clinical healing in patients clinically evaluated
- Microbiological resolution as a measure of microbiological efficacy [ Time Frame: 28 days ]
Compare microbiological efficacy of treatment with colistin vs meropenen in VAP.
The putative pathogen is eliminated from repeated culture of lower respiratory tract.
- Number of participants with adverse events as a measure of safety and tolerability [ Time Frame: 28 days ]The evaluation of security will be carried out through collection of adverse events that occur during the trial
