About this study

De-escalation aims at reducing the use of broad-spectrum antibiotics and therefore the emergence of multidrug-resistant (MDR) pathogens.

Observational studies suggested that this strategy seems to be safe. However, there is no adequate, direct evidence showing de-escalation of antimicrobial agents to be effective and safe for onco-hematology patients with sepsis or septic shock. Thus, randomized clinical trials are needed for testing the safety and efficiency of de-escalation of antimicrobial therapy.

The investigator's hypothesis is that de-escalation of empirical antimicrobial therapy in onco-hematology patients with sepsis or septic shock is noninferior to the continuation of empirical antimicrobial therapy.

The first aim of the study is to demonstrate that de-escalation is noninferior to the continuation of broad-spectrum antibiotics in terms of hospital mortality.

The secondary aims are to compare the two strategies in terms of mortality, duration of antimicrobial therapy, durations of mechanical ventilation, vasopressor use, numbers of superinfections, organ failure.

Antimicrobial de-escalation (ADE) of antimicrobial therapy is a strategy proposed to allow for the rational use of broad-spectrum antimicrobial therapy as the empiric treatment for infections and minimize the overall exposure to these broad-spectrum agents. The need for prompt, effective antimicrobial therapy for patients with known or suspected infections is widely accepted. This principle leads to the use of very broad-spectrum antimicrobial therapy to increase the odds that all suspected potential pathogens are adequately treated. However, the potential drawback is selection of multidrug-resistant (MDR) organisms.

ADE is widely recommended in the management of antimicrobial therapy in intensive care unit (ICU) patients. The Surviving Sepsis Campaign guidelines describe and recommend the process for selecting antimicrobial therapy as commencement of antimicrobials within the first hour, antimicrobial therapy broad enough to cover all likely pathogens, and daily reassessment for potential ADE.

To date, no randomized study assessing this strategy is available for this specific population of cancer critically ill patients. In a recent systematic review based on 13 observational studies and one randomized controlled trial, the authors conclude that the equipoise remains and a large randomized trial is required to assess the effect of the antibiotics de-escalation strategy on the bacterial ecosystem, on MDR carriage, and on patient outcomes.

Study groups in NCT03683329
Study groupRoleWhat they receive
Antibiotic de-escalationExperimental* According to the results of the antibiogram of the suspected causative bacteria, the ''pivotal'' antibiotic (antipseudomonal betalactam) used for empirical treatment is switched to an antibiotic with a spectrum as narrow as possible according to the targeted pathogens, * Stop the companion antibiotic (aminoglycoside, fluoroquinolone, macrolide) between day 2 and day 3 of antibiotic treatment as much as possible, * Stop the empirical antibiotic directed against methicillin-resistant staphylococcus aureus (MRSA) or an enterococcus in the absence of these bacteria in the culture.
Receives: Other: Antibiotic de-escalation
Standard treatment without de-escalationActive comparator* The companion antibiotic is stopped between day 3 and day 5 of antibiotic treatment as much as possible and according to the local prescription, * Empirical antibiotics directed against MRSA or enterococcus were used according to local prescription and/or international guidelines, * The pivotal antibiotic of the empirical treatment is continued for the entire duration of the treatment, independently of microbiological results. For prolonged treatment, the physician has the choice of de-escalating after 8-15 days of treatment.
Receives: Other: Standard treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Antibiotic de-escalation and Standard treatment in people with Critical Care and Cancer, run by Institut Paoli-Calmettes at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hospital mortality (time frame: From day of inclusion until day of ICU discharge, up to 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Feb 2026.
