About

Antibacterial drugs are facing increasing limitations in terms of effectiveness due to emergence resistance. Improved antibacterial drug monitoring approaches are particularly needed in nosocomial infections occurring in ICU patients, including ventilator-associated pneumonia and ventilator-associated tracheobronchitis, where decreased susceptibility of the etiological organisms is observed worldwide and pharmacokinetic alterations frequently observed.

No routine drug monitoring is available for betalactams at the point of care in a useful time frame (i.e., within a few hours after having collected the blood specimens).

The purpose of this study is to compare MON4STRAT approach for reaching and maintaining a meropenem pre-determined PK-PD target when compared to conventional meropenem dose.

2. Currently intubated and mechanically-ventilated subjects in the ICU
3. Suspicion of lower respiratory tract infection
4. Presence of Gram-negative organism(s) by Gram stain OR by culture of pre-therapy respiratory specimen (eg, endotracheal aspirate [ETA], bronchoalveolar lavage [BAL], or mini-BAL) OR previous colonization 48 h before screening.
5. Initial empiric antimicrobial meropenem regimen
6. At least two risk factors for multidrug-resistant organisms
7. Provision of written informed consent by the subject or a family member or a close relative or waiver of consent.

Exclusion criteria
