Studies are evaluating novel Microbiome Metabolic Therapies, KB195 and KB174, in target patient populations; data expected in Q4 2019
Third non-IND clinical study in healthy subjects also underway to evaluate dosing of KB174
LEXINGTON, Mass., March 21, 2019 (GLOBE NEWSWIRE) -- Kaleido Biosciences, Inc. (KLDO), a clinical-stage healthcare company with a differentiated, chemistry-driven approach to leveraging the potential of the microbiome organ, today announced the initiation of dosing in two non-Investigational New Drug (non-IND) clinical studies evaluating KB195 in patients with urea cycle disorders (UCD) and KB174 in patients with cirrhosis. A third non-IND clinical study evaluating various doses of KB174 in healthy subjects is also underway.
The gut microbiome plays a significant role in the production and consumption of ammonia, which is central to the pathogenesis of several ammonia processing-related diseases. KB195 and KB174 are novel Microbiome Metabolic Therapy (MMT™) product candidates intended to reduce net ammonia production by modulating the metabolic output and profile of the microbiome.
“As we continue to advance the development of our novel MMTs, we are pleased to have initiated dosing in these patient studies and anticipate results during the fourth quarter of 2019,” said Alison Lawton, President and Chief Executive Officer of Kaleido. “Importantly, we are also poised to initiate additional studies of our MMTs throughout the year, including a Phase 2 IND clinical trial in UCD, and a non-IND clinical study evaluating another MMT, KB109, in our multi-drug resistant pathogens program. Data from these studies will help inform future development of our programs and the potential of our MMTs to address important patient needs.”
KB195 Non-IND Clinical Study in UCD
Urea cycle disorders (UCD) are a group of serious, life-threatening, rare genetic diseases caused by a deficiency in one of the six enzymes or two amino acid transporters that constitute the urea cycle, resulting in an impaired ability to process ammonia.
This non-IND clinical study is expected to enroll approximately 5 UCD patients aged 14 and older on standard of care, who will receive KB195 orally for 21 days. The study will evaluate the safety and tolerability of KB195 in patients with UCD, as well as its effect on ammonia levels as measured by nitrogen metabolism in the blood and urine.

KB174 Non-IND Clinical Study in Cirrhosis
Hepatic encephalopathy describes a spectrum of potentially reversible neurologic and psychiatric abnormalities generally seen in patients with liver failure. It is a common complication of all forms of cirrhosis, leading to significant morbidity and mortality in this patient population. Elevated ammonia in the blood is central to the pathologic process that causes encephalopathy.
This randomized, double-blind, controlled non-IND clinical study is designed to evaluate KB174 compared to a negative control, maltodextrin, in adult patients with well-compensated cirrhosis. Approximately 36 patients are expected to be enrolled and following an amino acid challenge will be randomized to receive either KB174 or maltodextrin orally for 28 days. This study will evaluate nitrogen metabolism in the blood and urine, and safety and tolerability.
Additional information on this study can be found at https://clinicaltrials.gov/ using identifier NCT03855956.
KB174 Non-IND Clinical Study in Healthy Subjects
Kaleido has also initiated dosing in a non-IND clinical study to evaluate various dosing levels of KB174 in healthy subjects in a model designed to assess nitrogen metabolism. Approximately 48 subjects will be randomized to one of four different dose groups and receive KB174 orally for 20 days. Following a protein challenge, markers of nitrogen metabolism in the blood and urine will be measured, and safety and tolerability will also be evaluated.
