Rationale: Subjects with the metabolic syndrome have an increased risk of developing cardiovascular disease and a twofold risk of developing hypertension. A functional food ingredient with the ability to improve arterial stiffness, microcirculation and/or the ability to reduce blood pressure could potentially contribute to the delay or prevention of a range of cardiovascular diseases and could provide additional complimentary alternatives to pharmacological and lifestyle based interventions in the maintenance of cardiovascular health.
Objective: To assess the acute (2h) and short term (2 days and 4 week) effects of daily administration of 5g of NWT03 (an egg-protein hydrolysate) on carotid-radial Pulse Wave Velocity (cr-PWV). Secondary objectives are to assess its effects on carotid-femoral PWV, characteristics of microcirculation, systolic and diastolic blood pressure, lipid and lipoprotein metabolism, glucose metabolism and incretins.
Study design: Investigators propose to carry out a randomized, double-blind, placebo controlled crossover study.
Study population: Eligible subjects will be male or female, non-smokers between 18-75 years of age and will be otherwise healthy, but meeting at least three criteria of the Metabolic Syndrome (MetS). It is estimated that 80 otherwise healthy subjects with MetS will be randomised, to result in a minimum of 72 evaluable subjects (drop out maximal 10%) at the end of the study.
Intervention: Subjects will be randomly allocated to receive 5g of NWT-03 and placebo, once daily, on separate occasions, for a period of 4 weeks and with a washout period between the two interventions of typically 4 weeks. However, this period may be shortened by 2 weeks or extended by 8 weeks, depending on the availability of the subject. Total study duration will be 10 - 16 weeks, depending on the duration of the washout period.
Main study parameters/endpoints: Measurements will be performed at the start and end of each 4-week intervention period. Effects of NWT-03 supplementation will be calculated as the absolute differences between values obtained at each period. The main study endpoint is the change in cr-PWV.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Before the study starts, subjects will be screened to determine eligibility during a screening visit. During this visit, body weight, height, waist circumference and blood pressure will be measured and a venous blood sample (10 mL) will be collected. During the study, subjects will receive NWT-03 and placebo powders in random order and are asked to consume it on a daily basis. At visits 2, 3, 4, 5, 6 and 7 (days 0, 2, 27, 56, 58 and 83 of the study), cr-PWV, cf-PWV and office blood pressure will be recorded. A fundus photograph and a blood sample (20mL) will be taken in fasting condition. 2 hours after intake of the designated study product cr-PWV, cf-PWV and office blood pressure will again be measured and another fundus photograph will be taken. Additionally, a blood sample (20 mL) will be collected. Thus, in total 270 mL blood will be drawn. A pregnancy test will be taken in females of childbearing potential at visits 2 and 5. Subjects will be asked to fill out a food frequency questionnaire and to provide a spot urine sample at visits 4 and 7. Furthermore, subjects will be asked to keep a study diary throughout the duration of the study. Total time investment for the subjects will be approximately 19 hours. Apart from bruises or hematoma, rarely induced by blood sampling, no risks are associated with participation in this study.
