Study Overview
Brief Summary
This study evaluates the effect in HbA1c levels of a once daily administration of plant-based hydrolysates in pre-diabetic, but otherwise healthy volunteers. Among the 63 subjects enrolled, 21 will receive a plant-based hydrolysates from one cereal, 21 will receive a plant-based hydrolysates from another cereal and 21 will receive a placebo.
Detailed Description
Pre-clinical data on human skeletal muscle cells and mouse Type 2 diabetes model have shown a blood glucose lowering effect of the plant-based hydrolysates.
The first objective of the study is to evaluate the effect of a once daily administration of 2 different cereal protein hydrolysates versus placebo, when consumed over a 12-week period, at reducing the preferred outcome measure identified by the European Food Safety Authority i.e. glycated haemoglobin (HbA1c) levels in pre-diabetic volunteers who are otherwise healthy subjects.
The second objective of the study is to evaluate the effect of a fixed daily administration of 2 different cereal protein hydrolysates versus placebo, when consumed over a 12-week period on further supportive measures like Post-prandial glucose/insulin levels, fructosamine level, fasting plasma glucose level, vital signs and blood pressure, weight and BMI.

Exclusion Criteria

The Principal Investigator will discuss any uncertain cases directly with the study sponsor prior to inclusion of any such subjects)
- •Low hemoglobin or hematocrit (i.e., lower than normal ranges specified and in-use at the local laboratory designated for this study),
- •Females are pregnant, lactating or wish to become pregnant during the study.
- •Participation in a clinical trial with an investigational product within 90 days before pre-screening, or plans to participate in another study during the study period,
- •Subject has a history of non-compliance
Arms & Interventions
12 weeks daily administration Placebo

Intervention: 12 weeks daily administration Cereal 2 (Dietary Supplement)
Outcomes
Primary Outcomes
Effect of the treatment on reduction of the HbA1c level (%)
Time Frame: 12 weeks
