Monoclonal Microbial Therapies
as a new class of medicines
EXELIOM BIOSCIENCES
(former Nextbiotix)
Our goal is to leverage the central role of the gut microbiota in the immune system.
Our lead program is a monoclonal microbial drug candidate, using a single strain of the bacteria species Faecalibacterium prausnitzii.
This novel treatment aims at offering a complementary strategy to patients and physicians for the treatment of inflammatory bowel diseases, such as Crohn Disease or Ulcerative Colitis.
Our strain was rationally selected for its superior properties.
Faecalibacterium prausnitzii uniquely combines 4 characteristics:
-
Natural-occurring bacterial species in the human gut flora of all human beings across all geographies
-
Most abundant bacterial species in the gut microbiota of healthy subjects
-
Almost absent in patients with inflammatory bowel diseases
-
Predictive of good health in patients with inflammatory bowel diseases
We have observed in preclinical studies that orally-delivered pharmaceutical compositions of Faecalibacterium prausnitzii can downregulate immune responses and reduce pain.
Our Portfolio
We are working to advance our lead candidate into several clinical studies across inflammatory bowel diseases.
In parallel, we are also leveraging our technological advances and know-how to set-up a state-of-the-art platform specialized in the development of new monoclonal microbial candidates in other therapeutic areas.
