Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Following bowel resection due to cancer, up to 80% patients will experience variable and unpredictable bowel function and symptoms termed as Low Anterior Resection Syndrome (LARS). The exact mechanism of LARS remains unclear and currently there is no standard treatment.

This program of research will investigate if Faecal Microbiota Transplantation (FMT) can improve the bowel function and patient’s quality of life (QoL).


Phase 1- Dose-finding-study.
Group 1: FMT at one year post Ultra Low Anterior Resection (ULAR)/LAR via lower route (colonoscopy). Dose includes 4 x BiomeBoostTM FMT syringes, containing a total of 50 g of faecal matter as the active ingredient.

Group 2: FMT at one year post ULAR/LAR via lower route (colonoscopy). Dose includes 6 x BiomeBoostTM FMT syringes, containing a total of 75 g of faecal matter as the active ingredient.

FMT dose will be administered at one time, by the specialist conducting the colonoscopy (gastroenterologist/surgeon). The procedure of delivering FMT will only add 5 minutes to the routine colonoscopy being performed.

Adherence will be monitored by:
1. Dietetic phone follow up "How well did you follow the intervention" in a non judgmental format.

Group 3: Standard care, will be following their standard/normal care with no modifications.

This includes the patient following their "normal diet" and not taking any supplements such as prebiotics/probiotics that may alter the gut microbiome.

Statistical methods / analysis
All data analysis will be performed using IBM SPSS Statistics for Windows (Release 26.0, 2020; Armonk, NY: IBM Corp). The Shapiro-Wilk test will be used to test the assumption of normality along with visual check of instograms. Means and standard deviations will be presented as the descriptive statistics for normally distributed data. Medians and interquartile ranges are described for non-normal data. Categorical data will be summarised with frequencies and proportions. A mixed model ANOVA will be used to investigate impact of each intervention group on bowel symptoms and QOL scores and over four time points. Intention to treat analysis will be undertaken. The model will account for non-compliance, drop outs and other relevant confounding factors such age, gender, severity of bowel disease and others. Statistical significance will be obtained if the Bonferroni-adjusted p<0.05.

Primer7 and Permavona+ (PRIMER-E, Plymouth) will be used to analyse microbiome data (multivariate). Firstly, Principal Coordinates Analysis will be used to visualize the data, followed by distance-based linear models and redundancy analysis for a closer analysis. This will be also done to interpret findings with other data (such as Composition) which can assist in understanding the relationship between the two.

Summary
Brief summary
Following bowel resection due to cancer, up to 80% of patients will experience variable and unpredictable bowel function and symptoms termed as Low Anterior Resection Syndrome (LARS). The exact mechanism of LARS remains unclear and currently there is no standard treatment. Research shows that the gut microbiome, also known as gut bacteria, is changed in patents following bowel cancer and may be linked with LARS and the changes in bowel function and symptoms experienced. This program of research therefore aims to examine the effect of Faecal Microbiota Transplantation in LARS symptoms, the gut microbiome and quality-of-life.

Who is it for?
You may be eligible for this study if you are aged 19 years or older, have had an ileostomy reversed with a background of low anterior resection or ultra-low anterior resection due to adenocarcinoma of the colon or rectum, and are experiencing symptoms of minor or major LARS.

Study details
Participants will be randomised (i.e. allocated by chance) to receive one of two different doses of faecal microbiota transplant, or standard care. Faecal microbiota transplant involves administering faecal matter via a syringe using colonoscopy, which requires insertion of a flexible tube into the rectum, and will take an addition of approximately 5 minutes to your routine colonoscopy to complete. Participants allocated to standard care will not receive a faecal microbiota transplant. All participants will answer a number of questionnaires about bowel function and quality of life, and will provide a stool sample for analysis at baseline and week 4 of the study. Participants will also provide a blood sample to assess their immune response and signs of inflammation at baseline and week 4 of study.

It is hoped that this research will show that faecal microbiota transplant is an effective treatment for reducing symptoms of LARS and improving quality of life in patients who have undergone a low anterior resection.
