Brief Summary

The purpose of thus study is to determine if faecal microbiota transplantation will result in improvement in clinical outcomes in patients with irritable bowel syndrome.

Detailed Description

1. Background

Irritable bowel syndrome (IBS) is a chronic, debilitating, functional gastrointestinal disorder with estimated population prevalence in Europe between of 10 -15% (Ford et al). These symptoms can be debilitating and lead to a significant reduction in quality of life particularly in the more severely affected.

Alterations in the function and composition of the gut microbiota are increasingly being implicated as potential aetiological factors. (Collins et al). One of the strongest indictors for this concept is the significantly increased risk of developing IBS after an episode of acute gastroenteritis. Prospective studies have demonstrated that between 3- 36% of enteric infections lead to new, persistent IBS symptoms. (Gwee at al.,Neal et al) A number of studies have demonstrated that the diversity, stability and metabolic activity of the gut microbiota are altered in IBS patients compared with healthy individuals (Jeffrey et al). Although a distinct microbial signature has not been identified for IBS, several studies have shown a gut microbial composition enriched with Firmicutes together with a reduced abundance of Bacteroides (Jeffery et al, Rajilic-Stojanovic et al).

Faecal microbial transplantation (FMT) has proven to a safe, inexpensive and effective treatment for recurrent Clostridium difficile infection achieving up to 90% cure rates in some studies with a very good side effect and adverse event profile (van. Nood et al.). In this study the investigators wish to investigate whether restoring healthy gut microbiota profiles, using stool from healthy donors, will lead to improved clinical outcomes for patients with IBS.

Autologous fecal microbiota transplant using re - infusion of the participants own faeces has been previously been used as a placebo in studies using FMT (Vrieze et al)

2. Study Design

The design of the study is a prospective randomised, placebo controlled study that will be carried out on a single site. The study will involve four visits in total over an 8 week period. The first visit will be a screening visit to assess eligibility for the study. Visit two will be the treatment visit at which patients will receive the FMT using stool from a healthy donor or placebo. An autologous faecal microbiota transplant will be used as the placebo in this study. Follow up visits will be performed at 4 weeks and 8 weeks after the treatment.

Up to 50 patients with IBS will be recruited for the study. All patients will have an established diagnosis of IBS as per the Rome III criteria. Subjects will be recruited from the population of IBS patients attending Cork gastroenterology outpatients. Subjects will be randomly assigned to either the treatment group or placebo control group.

3. Donor Selection:

Donor stool will be obtained from healthy donors. The donors will be interviewed to ensure they are in good health and will undergo a screening questionnaire to identify potential infectious risk which could be transferred by stool. Certain exclusion criteria will apply and donors will undergo testing of stool and serum. The donation process is safe for the donor (Bakken et al). A selected healthy individual with a diverse microbial composition will preferentially be used as the donor candidate unless recipient wishes dictate the use of a designated donor.

3.1 Donor Exclusion criteria

Risk of infectious agent Known Human immunodeficiency virus, hepatitis B or C. Known exposure to HIV or viral hepatitis Known current communicable disease High risk lifestyle factors Factors which increase risk of Creutzfeldt-Jakob disease. Gastrointestinal co-morbidities History of inflammatory bowel disease History of IBS History of gastrointestinal malignancy or polyposis History of major Gastrointestinal surgery Factors that can or do affect the composition of the intestinal microbiota. Antibiotics within the preceding 3 months Major immunosuppressive medications Systemic anti-neoplastic drugs Additional recipient specific considerations Recent ingestion of a potential allergen where recipient has a known allergy. Systemic autoimmunity Atopic diseases Chronic pain syndrome Obesity.

3.2 Donor Testing

The following screening tests will be performed on all potential donors:

Stool testing Clostridium difficile by polymerase chain reaction (PCR) PCR for Shigella, Salmonella, E.coli verotoxin, Campylobacter Cryptosporidium Ova and parasites Serological testing HIV, type 1 and 2 Hepatitis A IgM Hepatitis B surface antigen, hepatitis B core antibody and hepatitis B surface antibody.

Hepatitis C screen human T-cell leukemia virus (HTLV) Rapid Plasma Reagin and fluorescent treponemal antibody absorbed.

4. FMT procedure protocol:

The following procedures should be followed in terms of donor and recipient preparation and in the preparation and administration of the donor stool.

1. Donor Preparation Can use gentle osmotic laxative the night before procedure. Provide the stool sample on the morning of the procedure.

2. Recipient Preparation Standard pre colonoscopy bowel preparation on the day before the FMT.

3. Stool preparation After passage of the stool by the donor it will be immediately be transferred to an anaerobic hood to be processed.

The stool will be diluted and filtered producing a liquid slurry consistency The liquid stool will then be placed in an anaerobic bottle and transferred to the site of administration.

4. Stool administration. The stool should be administered as soon as possible after it's prepared, at maximum 2 hours.

The FMT will be performed endoscopically. All patients will undergo a colonoscopy and the liquid stool will be infused through the endoscope.

Ideally all patients will also have a duodenal infusion of stool performed via an oesphogastrodoudenoscopy at the same session. However if the patient does not consent to this it will not be deemed a protocol breach.

5. Study Procedures:

The study will be conducted as outlined in this protocol and in accordance with the ICH Guidelines on Good Clinical Practice, and the declaration of Helsinki [Appendix A]. Informed consent will be obtained prior to any study related procedures being undertaken.

5.1.1 Screening Visit (Visit 1)

The aim of the study and the procedures to be undertaken will be explained to all potential subjects. Subjects will then be requested to read the subject information sheet and read and sign the informed consent form, and will receive a signed copy. The following assessments will be performed at Visit 1 Informed consent Demographics Medical and medication history Rome III questionnaire Evaluation of eligibility criteria Vital signs Physical examination, body weight, height and BMI assessment Food frequency questionnaire IBS symptom assessment scores Hospital Anxiety and Depression Scale International Physical activity Index Blood samples Stool samples

If the patient meets the eligibility criteria they will return within 28 days to undergo faecal microbiota transplantation.

5.1.2 Treatment Visit (Visit 2)

At visit 2 the patients will undergo faecal microbial transplantation. Prior to the procedure all patients should undergo standard bowel preparation. At Visit 2 the following assessments will be performed on all patient before FMT is performed Brief interview about the previous weeks Vital signs and physical examination. Eligibility assessment Informed consent for endoscopy.

The donor stool will be administered to the patient endoscopically. All patients will undergo colonoscopy and the donor stool will be infused through the colonoscope. Decision to perform duodenal infusion as well as colonic infusion will be dictated by patient preference. If the patient consents they will also undergo oesphogastrodoudenoscopy and donor stool will be infused through the gastroscope into the patients duodenum.

Following the procedure the patent will be managed in recovery as per standard endoscopy guidelines.

5.1.3 Visit 3 and 4 - Follow up visits.

At visits 3 and 4 the patients will undergo the following Interview about the previous weeks. Vital signs and physical exam incl BMI Concomitant medication Adverse events monitoring Blood samples for clinical and research. Stool sample (collected at home prior to visit). Food frequency questionnaire IBS symptom assessment scores Global assessment question. Hospital Anxiety and Depression Scale International Physical activity Index

5.2 Removal of subjects from the study

Subjects will be withdrawn from the study if the subject; Elects independently to withdraw from the study; If he/she develops any condition which contravenes the original criteria; Is considered at any point to be unsuitable to continue the study, at the discretion of the investigator.

5.3 Concomitant Medication

Subjects will be questioned about their medication history. The details of any medication taken will be recorded in the patient case notes and case report form

5.4 Endpoint assessments

Subjects will have the following endpoint assessments performed: assessment of medical and surgical history changes since baseline/treatment visits, IBS severity/QOL scores, faecal sample assessment/analysis, blood sample analysis, physical assessment, concomitant medication and adverse events.

To ensure subject safety the following evaluations will be performed during the study: vital signs, adverse event monitoring, physical examination and laboratory assessments

6. Biological Sample Collections and Analysis:

6.1 Blood

Blood will be collected at each visit for clinical haematological and biochemical analysis and cytokine analysis.

Haematology and biochemistry panels will be done as per standard of a care - Full blood counts (including haemoglobin, white cell count, platelet count, haematocrit and differential white cell count), erythrocyte sedimentation rate(ESR), sodium, potassium, chloride, urea, creatinine, protein, albumin, crp, liver function tests and quantitative immunoglobulin (IgA, Immunoglobulin G, IgM). Participants will also have HIV, hepatitis B, hepatitis C, HTLV and syphilis screens performed at visit 1. This analysis will be performed at Cork University Hospital (CUH) laboratories. All laboratory results will be reviewed and reports signed the investigators and recorded in the patients case repot form (CRF).

Research bloods for serum analysis of inflammatory immune markers including cytokines will be performed, theses bloods will be processed in the laboratories of the Alimentary Pharmabiotic Centre, University College Cork(UCC).

6.2 Faecal Sample

Faecal samples will be collected at each visit. Bacterial DNA will be extracted from the faecal samples of each subject and the composition of the microbiota determined by sequencing of amplified bacterial ribosomal ribonucleic acid (RNA) genes, before and after the faecal microbiota transplantation is performed. Faecal samples will also be analysed for viral particles and phageome studies performed.

6.3 Biopsy/ Intestinal Tissue Collections, Storage and Analysis

If the patient consents, during their endoscopy at time of FMT biopsy of intestinal tissue will be performed. The tissue samples will be collected in culture medium and stored at 4 0C until delivered to the lab in UCC. Microbiota composition analysis will be performed by direct pyrosequencing of 20,000-40,000 16S rRNA gene amplicons per subject (Pubmed: 20571116). Sequence generation and analysis performed by the UCC bioinformatics team will determine the composition of the microbiota of individuals.

6.4 Analyses

Analyses of all samples collected will be conducted in the CUH and/or UCC/Teagasc laboratories. On some occasions the analyses may be done in collaboration with a third party outside UCC including pharmaceutical companies, which may require samples to be shipped to this organisation. These samples will be coded and identified only using anonymised sample identifier numbers. In addition samples may be stored and used for analysis in future studies. Again samples will be coded and identified only using anonymized sample identifier numbers.

7 .Statistics and Study Powering:

A placebo response rate of 40% is predicted in this study population. The study will be appropriately powered to detect additional benefit of at least 15% in the treatment group compared to placebo.

The primary and secondary objectives will be analysed using standard parametric and non-parametric statistical techniques to test the efficacy of FMT. The exploratory objective will be assessed using sophisticated biostatistical analysis to identify a microbiota profile that predicts response to FMT.

8. Changes in the conduct of the study or planned analyses:

With the exception of emergency situations, any significant change in the protocol (i.e., one that affects the safety of the subjects, scope of the investigation, the scientific quality of the study) will not be implemented until the Independent Ethics Committee (IEC) have reviewed, approved, and documented the protocol amendment in writing. Amendments include changes in the investigator and investigators or site address, etc.
