Using cotrimoxazole to treat pneumonia in ICU patients

Official title: Efficacy of Cotrimoxazole as a De-escalation Treatment of Ventilator-Associated Pneumonia in Intensive Care Unit. Multicentric Non-inferiority Randomised Controlled Trial

Run by Assistance Publique - Hôpitaux de Paris · NCT05696093 · Data updated 2026-11-12

This study is testing if cotrimoxazole can effectively treat pneumonia in ICU patients on ventilators, compared to standard antibiotics, to see if it helps them recover better.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult ICU patients on mechanical ventilation for at least five days with microbiologically confirmed VAP due to susceptible Enterobacteriaceae.

Probably not a fit

Patients with hemodynamic instability or contraindications to cotrimoxazole will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicentre randomized non-inferiority trial evaluates the efficacy of cotrimoxazole as a de-escalation treatment for adult patients with ventilator-associated pneumonia (VAP) in intensive care units. Patients with microbiologically confirmed VAP due to Enterobacteriaceae susceptible to cotrimoxazole will be randomly assigned to receive either cotrimoxazole or standard antibiotic therapy for a total of 7 days. The study aims to optimize antibiotic administration based on the latest recommendations and will involve daily follow-ups until patient discharge or death. The trial will assess clinical outcomes, including vital status and potential new infections.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective and targeted approach to managing ventilator-associated pneumonia in ICU patients.

How similar studies have gone: Other studies have explored antibiotic de-escalation strategies, but the specific use of cotrimoxazole in this context is relatively novel.

Inclusion Criteria:

* Adult patients hospitalized in an ICU
* Under mechanical ventilation for at least five days
* Microbiologically confirmed VAP preferably on a distal lung sample (bronchoalveolar lavage or protected distal specimen) otherwise endotracheal aspiration
* Enterobacteriaceae susceptible to cotrimoxazole, and for polymicrobial VAP, all bacteria susceptible to cotrimoxazole
* 5\) Treated for at least 24 hours by an appropriate empiric antibiotic therapy (at least one effective antibiotic from the initiation of treatment for this VAP episode), and for polymicrobial VAP, all bacteria susceptible to empiric antibiotic therapy
* Stability of haemodynamic (stability or decrease in catecholamine dose) and respiratory (stability or improvement of FIO2) parameters

* Cardiac arrest without awakening
* Moribund state (patient likely to die within 24h)
* Limitation of life support (comfort care applied only) at the time of screening
* Enrolment to another interventional study on VAP care/management
* Pregnancy or breastfeeding
