E.1.2 | Classification code | 10024667 |
E.1.2 | Term | Liver cirrhosis |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether stabilising gut dysbiosis with FMT in patients with advanced cirrhosis is both feasible and safe |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are to provide preliminary
evidence of efficacy for a larger randomised trial, with the purpose of:
(i) Choosing the optimal primary outcome, and
(ii)Estimating the parameters for sample size calculation.
(a) As measured by an improvement in liver function tests at 90 days.
(b) The development of complications of cirrhosis such as infection or
bleeding.
(c) The development of any infection during the 90-day follow up
including chest, urine, stool, ascites (fluid accumulating in the abdominal
cavity)and blood infection.
(d) Stability of the transplant by comparing the composition of the
patient's stool on day 7, 30 and day 90 with the donor stool.
(e) Comparison of the bacterial composition of saliva with the stool at
baseline, day 7, 30 and day 90 . |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

• Inflammatory bowel disease (IBD)
• Coeliac disease
• HIV positive
• Immunosuppression e.g. more than two weeks treatment with corticosteroids within 8 weeks of intervention, active treatment with tacrolimus, mycophenylate, azathioprine

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoints of the study will be twofold:
(i) Assessment of the feasibility of FMT
c. Assess recruitment rates (including palatability of the intervention)
d. Assess tolerability of FMT e.g reflux rates
(ii) Assessment of the safety of FMT
Success Criteria of Primary Endpoints:
(i) Assessment of the feasibility and tolerability of FMT:
• >25% consent rate (of all patients screened ~250)
• >50% fulfil inclusion/exclusion criteria (of all patients consented ~64)
• >80% randomised patients treated successfully and completing study up to day 90 (out of those randomised ~22)
• Availability of obtaining sufficient stool donor samples for the study
• Reflux rates of transplanted material <20% (e.g. foul taste, smell, nausea and vomiting, indigestion)
• Significant gastrointestinal side effects (including diarrhoea, constipation, abdominal pain, flatulence and bloating) of <20%
(ii) Assessment of the safety of FMT:
•Incidence of any transmissable bacterial or viral infection that is deemed to have been acquired from the donor including Clostridium difficile infection.
•The development of any Serious Adverse Event (SAE), Serious Adverse Reaction (SAR) or Unexpected Serious Adverse Reaction (USAR) that is not pre-specified or is a known consequence of disease progression or complication of cirrhosis as outlined in section 7.2.5.1 that:
Results in death
Is life-threatening
Required hospitalisation or prolongation of existing hospitalisation
Results in persistent or significant disability or incapacity
Consists of a congenital anomaly or birth defect
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Patients will be assessed prior to the intervention and then again at 7
days, 30 days and 90 days after the placebo or FMT administration. |
|
E.5.2 | Secondary end point(s) |
The secondary objectives of the study are to provide preliminary evidence of efficacy for a larger randomised trial, with the purpose of:
(i) Choosing the optimal primary outcome, and
(ii) Estimating the parameters for sample size calculation.
(a) As measured by an improvement in global liver synthetic function as assessed by the MELD score [a composite score of serum bilirubin, creatinine and INR] at 90 days.
(b) Development of overt hepatic encephalopathy (grade 1 or more as measured by the Westhaven Criteria).
(c) The development of organ failure (hypotension requiring inotropic support, respiratory failure requiring ventilator support or the development of acute kidney injury requiring renal replacement therapy) and infection
(d) The development of any infection during the 90 day follow up including chest, urinary, stool, ascites and blood infection.
(e) Stability of the transplanted gut microbiome by comparing the % composition of the stool microbiota on day 7, 30 and 90 with the donor microbiome.
(f) Comparison of the composition of the salivary microbiome
with the stool microbiome as a surrogate marker of gut dysbiosis at baseline, day 7, day 30 and day 90 .
Mechanistic Outcome(s):
(i) Plasma endotoxin and bacterial DNA quantification at 7, 30 and 90 days.
(ii) Changes in faecal biomarkers (calprotectin, lactoferrin and M2-Pyruvate Kinase) at 7, 30 and 90 days.
(iii) Changes in leucocyte function including measurement by lipopolysaccharide-induced macrophage tumour necrosis alpha production and immunological markers using flow cytometry (HLA-DR and TLR-4 expression) at 7, 30 and 90 days.
