About Vedanta Biosciences

Vedanta Biosciences is leading the development of a new category of oral therapies based on rationally defined consortia of bacteria derived from the human microbiome. The company's clinical-stage pipeline includes product candidates being evaluated for the treatment of high-risk C. difficile infection, inflammatory bowel diseases, advanced or metastatic cancers, and food allergy. These investigational therapies are grounded in pioneering research - published in leading journals including Science, Nature, and Cell  -  to identify beneficial bacteria that live symbiotically within the healthy human gut, fight pathogens and induce a range of potent immune responses. Vedanta Biosciences controls a foundational portfolio of more than 40 patents and has built what is believed to be the world's biggest library of bacteria derived from the human microbiome. Proprietary capabilities include deep expertise in consortium design, vast datasets from human interventional studies and cGMP-compliant manufacturing of oral live biotherapeutics containing pure, clonally derived bacterial consortia in powdered form. Vedanta Biosciences was founded by PureTech Health (LSE: PRTC) and a global team of scientific co-founders who pioneered Vedanta's modern understanding of the cross-talk between the microbiome and the immune system.
