Effect of a Specific Phenolic Compound on Blood Pressure


Brief description of study

The study's main objective is to investigate the effects of acute consumption of a preparation containing 100 mg of a specific phenolic compound (patent pending, P201531587) on systolic BP after ingestion of a high fat meal.

Detailed Study Description

The study's main objective is to investigate the effects of acute consumption of a preparation containing 100 mg of a specific phenolic compound (patent pending, P201531587) on systolic blood pressure (BP) after ingestion of a high fat meal.

The secondaries objectives are:

  • To evaluate the effects on diastolic BP.
  • To study the phenolic compound bioavailability and to analyze its metabolites for determine the phenolic compound consumption biomarkers.
  • To evaluate the effects on endothelial function by ischemic reactive hyperemia (IRH).

The sample size was calculated using a previous studies using systolic blood pressure (SBP) as the primary outcome measure. A total of 14 subjects are needed, assuming variance components of approximately 20.0, to detect differences between treatments (placebo and phenolic product) of 10 mmHg, with a bilateral significance level of =0.05, a power of 80% and a standard deviation of 11.82 mmHg at the baseline.

To compare the main variable efficiency of the products of study as well as secondary variables of efficiency, will carry out analysis of the covariance (ANCOVA) with basal value as covariable, followed by the Tukey test for determining multiple differences. All tests will be carried out with significance to bilateral level of 5%. It is considered significant value p<0,05. The data will be analyzed using the "SPSS" program version 22.

The statistical analysis will follow the principles specified in the guidelines of the International Conference on Harmonization (ICH) E9 and CPMP/EWP/908/99 ICH E9 Points to Consider on Multiplicity Issues in Clinical Trials.
