Developing science

A novel and disruptive class of medicines built on the understanding of how gut bacteria interact with the body

The bacteria which colonise the human gastrointestinal tract – known as the gut microbiome – play an important role in health and disease

Our platform allows us to rapidly select gut bacteria which have a therapeutic effect in specific diseases

We have a broad and deep pipeline of live biotherapeutics, with programmes spanning GI, immuno-oncology, respiratory, autoimmune and CNS
