Study summary

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.

Study arms

  • Experimental
    Group 1: MON4STRAT Strategy

    Device: MON4STRAT Strategy

  • Active comparator
    Group 2: Conventional treatment

    Other: Control group

Interventions

  • DeviceMON4STRAT Strategy

    Meropenem infusion guided by daily Therapeutic Drug Monitoring (adjusted in order to reach predetermined PK/PD targets) using MON4STRAT device.

  • OtherControl group

    Meropenem 1 gram infused every 8 hours over 30 minutes, consistent with standard-of-care treatment and published guidelines. Meropenem doses will be modified according to SmPC recommendations.

What researchers measure

Primary outcomes

  1. To document the superiority of the MON4STRAT approach for reaching and maintaining a meropenem pre-determined PK-PD target when compared to conventional therapies.

    The proportion of time from day 1 after randomization to end of therapy (EOT) in which the free meropenem trough concentration in serum was maintained above 8 mg/L or above 4 x MIC if antibiotic MIC \> 2 and ≤ 8 mg/L, without exceeding 140 mg/L at peak level, as determined by a method of reference (HPLC).

    Time frame: During meropenem treatment: Day1 to Day 7

Secondary outcomes

  1. Clinical and microbiological response rates

    Time frame: Test of cure (TOC) visit (7 to 10 days after last study drug infusion)

  2. Time to LRT bacterial eradication, as assessed by follow-up cultures of ETA

    Time frame: Days 3, 5, 7 of treatment and at the end of treatment (EOT) visit

  3. All-cause mortality

    Time frame: Day 14 and day 28

  4. ICU and hospital length of stay

    Time frame: Up to day 28

  5. Number of mechanical ventilation-free days, defined as the number of days of unassisted breathing

    Time frame: Up to day 28
