CompletedNA

Sponsor: Rousselot BVBA

Conditions: Healthy, Prediabetic State

Interventions: Collagen hydrolysate, Placebo

Countries: Germany

To investigate the effect of two different dosages collagen hydrolysate (CH) on postprandial blood glucose and insulin profile in prediabetic and normo-glycaemic subjects.This will be investigated in a cross-over randomized double-blind placebo controlled study design.

Eligibility overview

Sex: ALL

Age: 18 Years to 70 Years

Healthy volunteers: Yes

Study type: INTERVENTIONAL

Eligibility criteria

Main Inclusion Criteria:

* Prediabetic subjects: Male and female subjects with prediabetic HbA1c values between 5.7% and 6.4% and/or fasting glucose ≥ 100 mg/dL and ≤ 125 mg/dL (in venous plasma) (twice confirmed at two independent days if HbA1c is \< 5.7%) or Healthy normo-glycaemic subjects: fasting glucose \<100 mg/dL and HbA1c is \< 5.7%
* Age: 18-70 years
* Body mass index 19-35 kg/m2
* Current Non-smoker
* 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

Main Exclusion Criteria:

* Subjects with diagnosed Type 2 Diabetes mellitus with medical treatment
* Presence of disease or drug(s) influencing digestion (incl. recent intake of antibiotics) 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)
* 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
* Intake of food supplements known to affect glucose tolerance, e.g., cinnamon capsules, conjugated linoleic acids
* Drug-, alcohol- and medication abuses
* Pregnant or breast-feeding women
