Clinical Trial Summary

Worldwide almost 40% of the adult population is overweight (including >10% obese), and more than 350 million children (up to the age of 19) are overweight. Overweight and obesity are significant problems and important risk factors for several lifestyle-related diseases, such as cardiovascular disease, certain cancers, non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D). Excessive consumption of glucose/sucrose is a major contributor to overweight and obesity. Alternative, low-calorie sweeteners could reduce daily energy intake and thus slow down the development of these conditions and related diseases. (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one is a sweetener that may be suitable for use as a sugar substitute; it is only partially digested in the small intestine and as a result has a lower energy density than more traditional sweeteners such as sucrose. However, it is not yet known to what extent (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one is used in the body and then excreted. The aim of this study is to measure the metabolic utilization (the 'mass balance') of a single dose of 14C-labelled (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one and AMS technology. Based on clinical data of excretion (urine and faeces) and CO2 production (expired air), the mass balance can be derived. These generated results will be used to map the metabolic pathways (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one undergoes during the digestion process. In addition, it will provide insight into the use of AMS technology to investigate the relationship between diet and health.

Description:

Objective: To determine the mass balance of (3S,4S,5R)-1,3,4,5,6-Pentahydroxy-hexan-2-one (low GI sweetener) in healthy volunteers. Study design: Single centre, open-label, non-randomised, single oral administration study Study population: 8 healthy males and females (18-65 y, BMI 18.5-25 kg·m-2) Intervention: Orally ingestion of 14C-labelled (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one, followed by a 72-hour test period during which all urine and faeces will be collected, as well as repeated sampling of blood and expired air, as well as indirect calorimetry measurements. Main study parameters/endpoints: Mass balance of (3S,4S,5R)-1,3,4,5,6-Pentahydroxy-hexan-2-one following 14C-(3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one ingestion. Secondary endpoints: content of 14C-labelled metabolites in carbohydrate metabolism pathways, routes of elimination of (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one. Ventilated hood measurements will be used as proof of concept to assess caloric value of carbohydrates. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Insertion of the catheters in a vein is comparable to a normal blood draw and the only risk is a small local hematoma. (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one ingestion might lead to gastro-intestinal discomfort. During the adaptation period participants will consume food-grade (3S,4S,5R)-1,3,4,5,6-pentahydroxy-hexan-2-one, which is safe for human consumption.
