Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will receive faecal microbiota transplantation (FMT) via enema from donor stool. Participants will receive enemas weekly for three weeks in total.

Faecal transplants will contain stool from healthy donors who are rigorously screened for infection or co-morbid conditions prior to donation. The stool donations are processed by the principal investigator who is a physician (FRACP) and clinical microbiologist (FRCPA). The stool is transferred to an anaerobic biosafety chamber within 2 hours of passage to preserve the microbes and blended with sterile normal saline and pharmaceutical grade glycerol within the chamber. The final composition of the faecal transplant contians 25% stool, 65% saline and 10% glycerol. Individual transplants are frozen at -80C . The transplants from a minimum of 3 to a maximum of 10 donors will subsequently be pooled prior to the transplants being administered so that every participant in the trial receives the same FMT.

Each transplant consists of a 67mL enema. These will be administered by one of the study investigators all of whom are trained physicians. The procedure should take no more than 30 minutes.

Treatment: Other
Comparator / control treatment
Participants in the control group will be given their own stool in the enema, this will serve as a placebo stool transplant.

Eligibility
Key inclusion criteria
1. Patients with refractory or recurrent infection–defined as at least 3 episodes of infection requiring at least 3 episodes of antibiotic therapy in preceding 24 months.
2. These infections were caused by a Gram negative bacterium which has acquired clinically important antibiotic resistance. This is defined as reported resistance to one or more of the following antibiotics: meropenem, ceftriaxone, cefepime, ceftazidime, cefalexin, amoxicillin-clavulanate, piperacillin-tazobactam, ciprofloxacin, gentamicin or trimethoprim.

Can healthy volunteers participate?
No
Key exclusion criteria
1. Active gastrointestinal infection
Ie bacterial or viral infection causing symptoms of diarrhoea
(colonisation with MRGNB is not considered to be an infection)
2. Pregnancy
3. Current use of antibiotics*
4. Cognitive impairment
5. Perianal inflammation
6. Life expectancy < 1 year
7. Neutropaenia <0.5 X109/L

Efficacy
Statistical methods / analysis
The sample size for the study was calculated using a binary outcome superiority trial power calculation. From animal study data, we expect at least an approximately 80% success in the intervention group and a 20% elimination rate in the placebo group. Significance level (alpha) was 0.05 with a power of 90%. This yielded a sample size required per group of 10 with a total sample size of 20.

Recruitment
Recruitment status
Stopped early
Data analysis
Data analysis is complete
Reason for early stopping/withdrawal
Participant recruitment difficulties
Other reasons/comments
Other reasons
Trial had to be terminated because of changes in the regulation of FMT (faecal microbiota transplant) products by the TGA. This regulation prohibits use of pooled stool donations (used in this trial), even in a research context. At the time of termination we had not enrolled enough patients to assess outcome.
