About this study
Official title: A Randomized Clinical Study of the Decolonization of MDR Gram-negative Bacteria in Patients With Haematological Malignancies
MDR (multidrug resistant) gram-negative bacteria have emerged as an important cause of bloodstream infection in hospitalized patients, especially in immunocompromised hosts. It was previously shown, that intestinal colonization with extended-spectrum β-lactamases (ESBL)-producing or carbapenem-resistant Enterobacteriaceae, carbapenem-resistant A. baumannii and P. aeruginosa) is a clinical predictor of bloodstream infections in patients with haematological malignancies and/or haematopoietic stem cell transplantation [Stoma I. et al., 2016].
To the investigators knowledge no randomized, placebo-controlled clinical trial has been performed to study the efficacy and safety of selective intestinal decolonization strategies in high-risk patients with haematological malignancies. Possible decolonization of MDR gram-negative bacteria in haematological patients could be important for the patient by reducing the risk of infection and for the community by reducing the risk of transmission.
The purpose of the proposed study is to assess the efficacy and safety of selective intestinal decolonization of MDR gram-negative bacteria with oral administration of Colistimethate sodium in high risk patients with haematological malignancies.

Clinical summary

It was previously shown, that intestinal colonization with extended-spectrum β-lactamases (ESBL)-producing or carbapenem-resistant Enterobacteriaceae, carbapenem-resistant A. baumannii and P. aeruginosa) is a clinical predictor of bloodstream infections in patients with haematological malignancies and/or haematopoietic stem cell transplantation [Stoma I. et al., 2016].

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Colistimethate Sodium in people with Hematological Infection, run by Minsk Scientific-Practical Center for Surgery, Transplantation and Hematology at 1 site in Belarus.
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 2 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 28 Dec 2017. 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 Belarus. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Rate of eradication of ESBL-producing or carbapenem-resistant Enterobacteriaceae, carbapenem-resistant A. baumannii or P. aeruginosa at day 21 post-treatment (time frame: 21 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02966457, which also lists 3 linked publications.
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 28 Dec 2017; AzTrials last refreshed its copy on 7 Nov 2026.
