“It is suggested that this simple yet rational therapeutic method should be given more extensive

clinical evaluation.”

- Mr Ben Eiseman, 1958

4th century: Ge Hong described use of human faecal suspension by mouth for diarrhoea and food poisoning “Zghou Hou Bei Ji Fang” Handy Therapy for Emergencies

16th century: Li Shizhen prescribed fermented faeces for abdominal diseases with diarrhoea, abdominal pain, fever, vomiting and constipation; “yellow dragon soup” “Ben Cao Gang Mu ” Compendium of Materia Medica

- Optimal route of administration?

- Optimal processing protocol (aerobic/anaerobic)?

- Optimal dosage?

- Donor characteristics?

- Optimal donor screening protocol?

- Donor patient compatibility?

- Optimal cyroprotectant (glycerol vs PEG vs DSMO vs custom mixes)

- Long term sequelae?

- Suitable for paediatric populations?

- Bowel lavage?

- Encapsulation?

Faecal Microbiota Transplantation (FMT): challenges

Doctors have to source

suitable donors

Then they have screen donors for transmittable

diseases

Then they have to process samples using

budget equipment and limited staff

FMT is currently administered through

invasive medical procedures

The entire process can take more than

three months

Faecal Microbiota Transplantation (FMT): challenges

• ISO:9001 controlled donation • Active donor registry

• cGMP ready facility set up • Trained & Qualified Staff • Isolator technology

• Several batches produced and quality released

• Capsule in development

• First Minister/CMO opening • NHS Tayside collaboration

• Applied for GMP License • Inspection June 18

Summary

- FMT is a relatively safe and powerful treatment option for

recurrent CDI

- FMT is a powerful research tool when combined with stratification of

responders and the interrogation of the associated microbial changes

in patients

Licensed facilities will expand access for patients in hospital,

EnteroBiotix seeking to be supplying hospitals by Q2 2018

Encapsulation expected to aid the design of placebo controlled trials and

further expand access. EnteroBiotix seeking to supply capsules by Q4 18

Advances in technology set to allow for precision microbiome engineering

and there are many novel technologies moving towards clinic
