Ferring Pharmaceuticals and its US subsidiary Rebiotix are developing a first-in-class microbiota-based live biotherapeutic, RBX2660, against recurrent C. difficile infection. Abi Millar profiles this investigational therapy and finds out where it lies in the growing trend for developing drugs that target the microbiome.
Clostridium difficile, also known as C. diff, often traps patients in a vicious cycle. A bacterial infection causing persistent diarrhoea and GI symptoms, C. diff typically affects people who have been treated with antibiotics, and whose balance of gut bacteria has been disturbed.

Some recurrences are due to a relapse of the initial infection, while others are due to being infected with a new strain.
