Clinical Study to Assess the Long-term Effect of Pep2Dia® on Glucose Homeostasis in Prediabetic Subjects

Clinical Study to Assess the Long-term Effect of Pep2Dia® on Glucose Homeostasis in Prediabetic Subjects: a 12-week Randomized, Multicenter, Double-blind, Placebo-controlled, Parallel Study

The goal is to assess the long-term effect of Pep2Dia® compared to placebo intake on blood glucose homeostasis. Respective improvements will be assessed by changes in glycated haemoglobin (HbA1c) before and after the 12-weeks intervention.

Inclusion Criteria:

• Male and female subjects (minimum one third of each gender) with prediabetic HbA1c values between 5.7% and 6.4% and/or fasting glucose ≥ 5.6 mmol/L (≥ 100 mg/dL) and < 7.0 mmol/L (< 125 mg/dL) (in venous plasma) (twice confirmed at two independent days if HbA1c is < 5.7%)
• Age: 25-70 years
• Body mass index 19-35 kg/m2
• Current Non-smoker
• Availability and presence in the study units for approx. 3.5 hours/ week for 2 times.
• Signed informed consent form
• No changes in food habits or physical activity 3 months prior to screening and during the study
• If applicable, stable intake of chronic medication of at least 4 weeks

Exclusion Criteria:

• Subjects with diagnosed Type 2-Diabetes with medical treatment
• Presence of disease or drug(s) influencing digestion and absorption of nutrients
• Intake of medications known to affect glucose tolerance, e.g., diabetic medication SGLT-2 inhibitors, GLP-1 receptor agonists, steroids, protease inhibitors or antipsychotics
• Chronic intake of substances affecting blood coagulation (e.g. acetylic acid (100 mg as standard prophylactic treatment allowed when dose is stable 1 month prior to screening), anticoagulants, diuretics, thiazides (diuretics and thiazides allowed e.g. for hypertension treatment when dose is stable 1 month prior to screening)), which in the Investigator's opinion would impact patient safety
• Severe liver or renal disease or laboratory evidence of hepatic dysfunction (i.e. alkaline phosphatase, ALT, AST >3 x ULN)
• Acute gastrointestinal diseases including diarrhea and/or vomiting within the last 2 weeks
• Known inflammatory or malignant gastrointestinal diseases (i.e. colitis ulcerosa, Morbus Crohn, celiac disease, malignant diseases e.g. colon-cancer, rectum cancer, pancreatitis)
• Clinically relevant findings as established by medical history, physical examination, clinical laboratory and/or vital signs
• Major medical or surgical event requiring hospitalization within the previous 3 months
• Intake of food supplements known to affect glucose tolerance, e.g., cinnamon capsules, conjugated linoleic acids, omega-3 fatty acids
• Intake of antibiotics within 4 weeks before the test days
• Known alcohol abuse or drug abuse
• Pregnant or breast-feeding women
• Weight loss intervention or recent body weight change >5 kg during last 3 months
• Known or suspected allergy to any component of the investigational product(s) (e.g. milk protein)
• Blood donation within 4 weeks prior to Visit 1 or during the study
• Anticipating any planned changes in lifestyle for the duration of the study
• Participation in another clinical intervention study within the last 4 weeks and concurrent participation in another intervention clinical study
• Subject unable to co-operate adequately
