Its approach used synthetic glycans—nonliving, carbohydrate-based compounds designed to selectively influence the activity of microorganisms in the gastrointestinal tract and potentially address disease through changes in microbiome function. The company’s development programs included KB109, an investigational microbiome metabolic therapy studied in several clinical settings, including gastrointestinal disorders and infectious diseases. Kaleido also explored applications of its platform in areas such as immunology and oncology. Its programs were investigational and had not been established as approved treatments. Kaleido Biosciences was founded in 2015 and based in Massachusetts. After clinical and strategic challenges, the company announced plans to wind down operations and discontinue development activities. As a result, it is generally regarded as a former operating biotechnology company rather than an active commercial healthcare business.AI Generated. May Contain Errors.
