Kaleido Biosciences, Inc. is a clinical-stage healthcare company focused on microbiome organs to treat disease and improve human health. The Companyâs product candidates are Microbiome Metabolic Therapies (MMTs), which are designed to modulate the metabolic output and profile of the microbiome by driving the function and composition of existing microbes. It is advancing a pipeline of MMT candidates to address a range of diseases and conditions with unmet patient needs. KB109 and KB174 are the MMT candidates for development for the prevention of infections caused by multi-drug resistant (MDR) bacteria. The nomination of these candidates resulted from their performance relative to a range of other MMTs in ex vivo screening of microbiome samples from healthy volunteers as well as microbiome samples from intensive care unit patients in an experimental set-up that specifically focused on determining the potential of MMTs to decrease the relative abundance of a panel of pathogenic bacteria.
