The study will be a prospective multicentre, randomized, open-label comparative continuous vs. intermittent pivotal βL antibiotic infusion strategies and combination vs. monotherapy trial conducted with a 2X2 factorial design.~Patients will be randomized to one of four of the following treatment groups in a 1:1:1:1 ratio. Randomization will be stratified on the centre and the initial βL administered (meropenem versus other) to receive (i) βL antibiotic either as a continuous infusion: CID group or as intermittent infusion: IID group, and (ii) either at most 1 dose (short duration) : AMT group or 5 days (long duration) : ACT group of aminoglycoside~Arm A: continuous infusion dosing of a pivotal βL-AB (Antibiotics) (CID group) AND AG (Aminoglycoside) infusion for 5 days (long duration) as appropriate combination therapy (ACT group)~Arm B: intermittent infusion dosing of a pivotal βL-AB (IID = control group) AND AG infusion for 5 days (long duration) as appropriate combination therapy (ACT = group)~Arm C: continuous infusion dosing of a pivotal βL-AB (CID group) AND AG infusion at most 1 dose (AMT group)~Arm D: intermittent infusion dosing of a pivotal βL-AB (IID = group) AND AG infusion at most 1 dose (AMT group)~The primary objective of the study is to compare the 30-day mortality of patients with hospital-acquired sepsis in the ICU according to the mode of administration of the pivotal βL antibiotic (CID group vs. IID group).~The primary endpoint is the mortality rate at day 30 between CID and IID groups while the Co-primary objective is to compare the MAKE 30 (Major Adverse Kidney Events within 30 days) between patients that will receive an appropriate monotherapy with βL (AMT group) or an appropriate combination therapy with βL and 5 days of AG (ACT group).~moreover, The co-primary criterion is the percentage of patients with a MAKE 30, i.e. when patients met one of the following criteria within day 30: in-hospital mortality, receipt of renal replacement therapy (RRT) or persistent renal dysfunction (discharge serum creatinine/baseline serum creatinine ≥200%) between AMT and ACT groups.
Patients hospitalized in ICU with sepsis (infection with life-threatening organ dysfunction according to sepsis 3.0 definitions) presumably due to MDR-GNB (multidrug resistant Gram-negative bacteria). The study will be a prospective multicentre, randomized, open-label comparative continuous vs. intermittent pivotal βL (Beta Lactamine) antibiotic infusion strategies and combination vs. monotherapy trial conducted with a 2X2 factorial design.
