Its approach used engineered, non-systemic glycans intended to selectively nourish beneficial bacteria in the human microbiome and encourage the production of metabolites that could influence disease-related biological processes. The company’s development pipeline included KB109, an investigational synthetic glycan evaluated in gastrointestinal and infectious-disease applications, including studies involving COVID-19 and respiratory infections. Kaleido also investigated other microbiome-targeted candidates, including KB174 for phenylketonuria and additional programs aimed at metabolic, inflammatory and immune-related conditions. Kaleido Biosciences was founded in 2015 and was based in the United States. In 2022, the company announced plans to wind down operations and discontinue its development programs. As a result, Kaleido is principally of historical interest as a biotechnology company that pursued a chemistry-based approach to microbiome therapeutics.AI Generated. May Contain Errors.
