About this study

Official title: Faecal Microbiota Transplantation (FMT) in Patients With Irritable Bowel Syndrome (IBS): Optimizing the Treatment and Its Mechanism(s) of Action

Two hundrad patients are randomized to either 90 g transplant, 90 g transplant twice with 1week interval into the distal small intestine via working channel of a gastroscope, or to 90 g transplant into the coecum of the colon via working channel of a colonoscope. The patients shall complete 5 questionnaires measuring symptoms, fatigue and quality of life and collect a feces sample at the baseline, and at 3, 6 and 12 months after FMT. Dysbiosis and fecal bacterial are determined by using 16S rRNA gene.

Read the detailed description

Patients Two hundrad patients who fulfil Rome IV criteria for irritable bowel syndrome (IBS) shall be included in the study. All the IBS subtypes shall be included.

Donor Investigators are going to use the same super-donor they used in their previous randomised double-blind, placebo-controlled study. The donor is athletic Caucasian man aging 36 years. He is non-smoker and is completely healthy without any medication and with a BMI of 23.5. He is not relative to any of the patients in the trial. He was borne by vaginal delivery and breastfeed. He was treated 3 times with antibiotics during his life. He trains 5 times weekly an hour each time. He took regularly dietary supplements rich in proteins, vitamins, fibres and minerals that made his diet richer than average in these substances. He was screened according to the guidelines for donors for FMT. Before he was accepted as a donor the microbiota was analysed in a faecal sample using GA-map Dysbiosis test. The analysis revealed a dysbiosis index (DI)= 1, indicating normobiosysis. In addition, he had excess of bacteria belonging to the Firmicutes. His faeces shall be tested every third moth during the trial.

Protocol

The patients are randomized to either 90 g transplant, 90 g transplant twice with 1week interval into the distal small intestine, or to 90 g transplant into the coecum of the colon. The patients shall complete 5 questionnaires and deliver fecal samples at the baseline, and at 3 , 6 , and 12 months after FMT.

Faeces collection, preparation and administration Faeces from both the donor and patients shall be collected and stored at - 80•. Frozen faeces shall be thawed and each 30 g is dissolved in 30 mL of 0.9% sterile saline. The dissolved stool administrated to the patients, after overnight fast, through working channel of gastroduodeno-scope in pars descendent duodenum distal to the papilla of Vater or to the coecum through working channel of a colonoscope.

Analysis Questionnaires

  1. IBS symptom severity Scale (IBS-SSS).
  2. Birmingham Symptom scale.
  3. IBS-quality of life (IBSQo) Questionnaire.
  4. Short form of Nepean Dyspepsia Index (SF-NDI).
  5. Fatigue Assessment Scale (FAS).

Microbiome analysis Gut microbiota analysis is performed using the Genetic analysis-mapTM Dysbiosis test (Genetic Analysis AS, Oslo, Norway) by algorithmically assessing faecal bacterial abundance and profile (dysbiosis index, DI), and potential deviation in the microbiome from normobiosis. GA-map test is based on faecal homogenization, mechanical bacterial cell disruption and automated total bacterial genomic DNA extraction using magnetic beads. DI is based on 54 DNA probes targeting more than 300 bacterial strains based on their 16S rRNA sequence in seven variable regions (V3-V9). Twenty-six bacteria probes are species specific, 19 detect bacteria on genus level, and 9 probes detect bacteria at higher taxonomic levels. Probe labelling is by single nucleotide extension and hybridization to complementary probes coupled to magnetic beads, and signal detection by using BioCode 1000A 128-Plex Analyser (Applied BioCode, Santa Fe Springs, CA, USA). A DI above 2 shows a microbiota profile that differs from that of the normobiotic reference collection (DI 1-2: non-dysbiosis, DI: moderate, DI 4-5: severe dysbiosis).

What is being measured

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

  1. Change in IBS-SSS total score

    Irritable bowel syndrome-symptom severity score (IBS-SSS) is a visual analogue scale questionnaire with a maximum score of 500 points. A decrease in total score by ≥50 points is considered as a response.

    Measured: 12 months after FMT

Secondary outcomes (1)
  1. Change in the Dysbiosis index

    Dysbiosis index (DI) is a 5 -scale index. A DI above 2 shows a microbiota profile that differs from that of the normobiotic reference collection (DI 1-2: non-dysbiosis, DI 3: moderate, DI 4-5: severe dysbiosis)

    Measured: 12 months after FMT

Questions about this trial

What is this clinical trial studying?

A study testing Feces in people with Irritable Bowel Syndrome, run by Helse Fonna at 1 site in Norway.

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 6 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 22 Aug 2023. 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 Norway. 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.

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?

Change in IBS-SSS total score (time frame: 12 months after FMT). 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 NCT04236843, which also lists 4 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 22 Aug 2023.
