About this study

Official title: PreventiOn of DYSbioSis Complications With Autologous Fecal Microbiota Transplantation in acutE myEloid Leukemia Patients Undergoing Intensive Treatment: A Feasibility and Safety Study ODYSSEE STUDY

The investigators propose to use autologous fecal microbiota transplantation (AFMT) to acute myeloid leukemia (AML) patients treated with intensive chemotherapy and antibiotics in order to restore the balance of their intestinal microbiome and thereby eradicate treatment-induced multidrug resistant bacteria (MDRB), infection-related complications, as well as sequelae to the gastrointestinal tract. Therefore, the investigators propose to perform a single-arm multicentre prospective fecal microbiota transplantation (FMT) trial in AML patients receiving intensive chemotherapy, and who are usually heavily treated with broad-spectrum antibiotics during aplasia that generate a profound status of dysbiosis. For this purpose, at the time of admission and AML diagnosis, patients will be requested to donate stools that will be comprehensively screened, and if deemed appropriate according to protocol criteria, conditioned and stored frozen until future processing and transplantation after aplasia completion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of AFMT efficacy in dysbiosis correction by measure of microbiota diversity

    Comparison of Alpha and Beta diversity indexes at baseline, after chemotherapy and after AFMT will be performed

    Measured: 40 days

  2. Evaluation of AFMT efficacy in MDRB eradication based on bacterial culture

    MDRB carriage and resistome will be compared at baseline, after chemotherapy and after AFMT

    Measured: 40 days

Secondary outcomes (1)
  1. Definition of a dysbiosis biosignature using combination of biological parameters

    Microbiota sequencing results will be correlated with immune parameters

    Measured: 40 days

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Autologous Fecal Microbiota Transplantation in people with Leukemia, Myeloid, Acute, run by MaaT Pharma at 4 sites 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 3 inclusion and 17 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 9 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Evaluation of AFMT efficacy in dysbiosis correction by measure of microbiota diversity (time frame: 40 days). The study lists 2 primary outcomes in all. 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 NCT02928523, which also lists 1 linked publication.

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 9 Sep 2020.
