Brief Summary

Antimicrobial resistance is a major global problem, particularly in hospital-acquired infections (HAIs). Gram-negative bacilli (GNB), including Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii, are among the most common pathogens associated with multidrug resistance and HAIs. These bacteria are of special concern because few therapeutic options are available.

Traditionally, the duration of treatment for severe multidrug-resistant (MDR)-GNB infections is 14 days. Studies of severe infections by GNB, regardless of susceptibility profile, have shown that shorter antimicrobial treatments are not inferior to traditional durations of therapy and are associated with a lower incidence of adverse effects. However, there are currently no studies assessing whether shorter duration of antimicrobial treatment is effective for MDR-GNB.

This open-label, randomized clinical trial aims to assess the non-inferiority of 7-day antibiotic therapy compared to conventional 14-day treatment in severe infections by MDR-GNB.

Primary Outcome Measures

Name	Time	Method
Clinical failure	28 days after randomization	Incidence of clinical failure. Clinical failure is a composite outcome defined by the presence of one of the following: Infection relapse (infection anywhere in the body by the same MDR-GNB) or Death

Secondary Outcome Measures

Name	Time	Method
Days alive and free from hospitalization	28 days after randomization	Number of days in which patients are alive and out of the hospital
Days alive and free from any antibiotic therapy	28 days after randomization	Number of days in which patients are alive and free from any antibiotic therapy
Length of intensive care unit stay	28 days after randomization	Number of days in which patients stayed at intensive care unit
Acute kidney injury	28 days after randomization	Incidence of acute kidney injury, according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria
Confirmed infection by Clostridioides difficile	28 days after randomization	Incidence of Clostridioides difficile infection
Hemodynamic instability lasting more than 6 hours	14 days after randomization	Incidence of hemodynamic instability lasting more than 6 hours. Hemodynamic instability is defined as hypotension that requires the use of doses of dopamine above 15 mcg/kg/min, epinephrine above 0.1 mcg/kg/min, or norepinephrine above 0.1 mcg/kg/min
Other adverse events related to antimicrobial therapy	28 days after randomization	Incidence of any other adverse event related to antimicrobial therapy
Diarrhea for any cause	28 days after randomization	Incidence of any diarrhea. Diarrhea is defined as 3 or more episodes per day.
Occurrence of infections caused by other MRD-GNB or other bacteria	28 days after randomization	Incidence of infections caused by other MRD-GNB or other bacteria
