Kaleido Biosciences, Inc. was a clinical-stage biotechnology company focused on leveraging the therapeutic potential of the microbiome to treat a variety of diseases, including those involving the immune system and metabolism. The company's approach involved identifying and developing novel Microbiome Metabolic Therapies (MMTs™). In April 2022, Kaleido Biosciences filed for Chapter 11 bankruptcy and subsequently sold substantially all of its assets, effectively ceasing its primary operations. Prior to this, it was actively engaged in research and clinical trials for conditions such as Urea Cycle Disorders and Ulcerative Colitis.
Formerly served as the primary center for research and development, clinical operations, and corporate administration for the company's microbiome therapeutic programs.
The facility likely housed advanced laboratory spaces for microbiome research, analytical chemistry, and process development, alongside typical corporate office amenities. Specific architectural highlights are not widely publicized for a company of its nature and lifespan.
As a clinical-stage biotech, the work culture was likely characterized by a fast-paced, innovative, and science-driven environment. Teams would have been focused on research breakthroughs, clinical trial execution, and regulatory milestones. This is no longer applicable as operations have ceased.
The headquarters was significant as the nerve center for Kaleido's pioneering efforts in Microbiome Metabolic Therapies. It was where their scientific strategy was developed and executed before the company's bankruptcy.
Kaleido Biosciences was primarily U.S.-based, with its operations centered in Massachusetts. While its clinical trials might have involved sites or collaborations internationally, as is common in drug development, the company did not maintain a significant network of international offices. All global activities ceased with its bankruptcy and asset sale in 2022.
