Trial summary

The investigators will perform a multicenter, 2:1 randomized, double-blinded, placebo-controlled trial of AMR in patients with diarrhea predominant-IBS (IBS-D) diagnosed according to Rome III criteria and the IBS-QOL questionnaire. Central supply and quality control of donor material will be used to control bias. Read more about this study

About this study

Official title: Allogeneic Microbiota-reconstitution (AMR) for the Treatment of Patients With Diarrhea-predominant Irritable Bowel Syndrome - the AMIRA Trial

The investigators will perform a multicenter, 2:1 randomized, double-blinded, placebo-controlled trial of AMR in patients with diarrhea predominant-IBS (IBS-D) diagnosed according to Rome III criteria and the IBS-QOL questionnaire. Central supply and quality control of donor material will be used to control bias.

Primary endpoint is improvement of IBS-SSS (Severity Score System) compared to baseline. Secondary endpoints include changes in IBS-QOL, short term safety and one year follow up to control long term effects, safety and changes in and acceptance of donor microbiome after AMR using16S rDNA sequencing and quantitative diversity analysis.

Read the detailed description

This study assesses allogeneic microbiota reconstitution (AMR) as novel treatment to improve symptoms and quality of life of patients with diarrhea-predominant irritable bowel syndrome (IBS-D).

The investigators will perform a prospective multicenter, 2:1 randomized, double-blinded, placebo-controlled trial of AMR in patients with IBS-D diagnosed according to Rome III criteria and the IBS-QOL questionnaire.

The experimental intervention is an infusion of donor feces via gastroscopy. The placebo intervention is an infusion of sterile saline via gastroscopy.

Planned number of patients included in the study: 42 patients Planned per-protocol group: 33 patients

Questions about this trial

What is this clinical trial studying?

A study testing Allogeneic microbiota reconstitution in people with Diarrhea-predominant Irritable Bowel Syndrome, run by University of Ulm at 2 sites in Germany.

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 6 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 31 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Germany. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

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?

Decrease of the IBS-SSS questionnaire > 105 Points compared to baseline (time frame: 90 days after intervention). 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 NCT04095988, which also lists 22 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 31 Jan 2020.
