Crossing the next frontier
to give you a fair chance to fight

Exeliom Biosciences is a clinical-stage biotechnology developing next-generation immunotherapies for the treatment of chronic inflammation.

Our novel candidates harness microbiome-associated innate regulatory mechanisms to enhance patient's responsiveness to treatments
in conditions where inflammation hampers efficacy, including inflammatory bowel diseases, solid tumor cancers, and chronic infectious diseases.

Fighting
Chronic Inflammation...

Chronic, dysregulated and unresolved inflammation facilitates disease progression and treatment resistance in many conditions, including IBD, several cancers with solid tumors and some infectious diseases. 

EXL01 - Exeliom's lead drug candidate - is an oral, first-in-class single-strain live biotherapeutics (Faecalibacterium prausnitzii) with a novel mechanism of action that demonstrates enhanced activation of key regulators of the innate and adaptative immune systems. As such, it offers a novel strategy to resolve inflammation. 

Developing novel therapies that modulate the immune-system in a non-suppressive manner to resolve chronic inflammation constitutes a paradigm shift and a source of hope for patients. 



... in conditions where inflammation hampers efficacy of existing treatments

EXL01 is being evaluated in several clinical trials, including a phase I trial in Crohn's disease, two phase II trials in immuno-oncology in combination with immune checkpoint inhibitors (Gastric cancer and Non-small cell lung cancer), and one phase I/II trial in the prevention of recurrent C. difficile infection.
Two additional Phase II studies evaluated EXL01 are planned to start in end of 2024: one in hepatocellular carcinoma in combination with an immune checkpoint inhibitor and one in postoperative Crohn's disease.

Overall, more than 300 patients across 6 indications will receive EXL01, generating an extensive dataset to demonstrate its therapeutic and commercial potential.

Giving patients a fair chance to fight is why we seek out unexplored therapeutic solutions, and why we founded Exeliom Biosciences.
