About this study

Official title: Randomized, Parallel and Double Blind Placebo-controlled Study for the Evaluation of Both Acute and Chronic Role of Hesperidin Consumption in 100% Orange Juice

The primary aim is to examine both the acute and chronic effects of hesperidin consumption from 100% Florida orange juice in various doses on functional and systemic markers associated with cardiovascular disease (CVD) risks.

Read the detailed description

The aim of this study is to compare the effect of different doses of hesperidin in 100% Florida orange juice (OJ) when regularly or postprandially consumed on cardiovascular risk markers; in addition, the plausible role and mechanism of the hesperidin will be investigated.

The sample size was calculated using a previously available bibliography using systolic blood pressure (SBP) as the primary outcome measure. A total of 84 subjects per study product group were needed, assuming variance components of approximately 20.0, to detect differences between the three groups (control, orange juice and hesperidin-enriched orange juice (10 mm Hg)) with a bilateral significance level of α=0.05 and a power of 80 %.

The sample size was computed to be sufficient to detect differences between treatment groups regarding the evolution in time of SBP levels. Justification of chosen sample size is based on the clinically meaningful difference assigned to δ=10.0 mm Hg, which is equivalent to a difference of approximately 7.4 % in patients with baseline SBP levels of approximately 135 mm Hg. Thus, a sample of 252 participants can be used for the chronic three arm parallel trial design (84 subjects/arm) and will allow us to detect small but clinically relevant differences between the three groups with statistical robustness and direct interpretation in terms of the chronic treatment effect.

To the acute postprandial tests, the investigators have chosen n=20 subjects per arm according to the most studies that have addressed the metabolic effects of a postprandial intervention have been performed using a very similar number of subjects with statistically good quality results.

The statistical analysis will follow the principles specified in the guidelines of the ICHE9 and CPMP/EWP/908/99 ICHE9 Points to Consider on Multiplicity Issues in Clinical Trials.

The continuous efficacy variables will be analyzed by an ANCOVA (analysis of covariance) with the baseline value as a covariate.

The efficacy outcomes will be determined using the absolute values and absolute differences from the baseline. The efficacy analysis will be performed using the Available Data Only approach. In addition, the analysis of the primary efficacy variable will be performed with the Baseline Observation Carried Forward approach.

A suitable hypothesis test will be applied to the rest of the variables according to the nature of each variable, such as the Fisher exact test for categorical variables, Student's T-test for continuous variables and Mann-Whitney U test for ordinal scale variables.

The statistical tests will be applied with an α=0.05 two-sided significance level. Post-hoc analyses and comparisons between pairs of groups will be done as for exploratory purposes.

In addition, the statistical plan will be transferred to the application form of the electronic data collection report (e-CDR), which allows the improvement of data management, diminishes human errors (according threshold values of each outcome) and, overall, guarantees the maximum exploitation of human data in the context of statistical analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Systolic Blood Pressure

    During each visit, SBP will be measured after 5 min in a seated position in a comfortable room by the physician. The measurement will be taken in duplicate at 1-min intervals using an automatic sphygmomanometer (OMRON HEM-907; Peroxfarma, Barcelona, Spain), and the average of the two measurements will be calculated.

    Measured: Every 2 weeks for a total of 12 weeks.

Secondary outcomes (6)
  1. Diastolic Blood Pressure

    During each visit, diastolic BP will be measured after 5 min in a seated position in a comfortable room by the physician. The measurement will be taken in duplicate at 1-min intervals using an automatic sphygmomanometer (OMRON HEM-907; Peroxfarma, Barcelona, Spain), and the average of the two measurements will be calculated.

    Measured: Every 2 weeks for a total of 12 weeks.

  2. Ischemic reactive hyperemia (IRH)

    The endothelial-dependent vasomotor functions will be measured as IRH by a Laser-Doppler linear Periflux 5000 flowmeter (Perimed AB, Järfälla, Stockholm, Sweden)

    Measured: Every 4 weeks for a total of 12 weeks

  3. Platelet aggregation

    Multiplate analyzer, Roche

    Measured: Every 4 weeks for a total of 12 weeks

  4. Homocysteine

    Homocysteine concentrations will be measured by liquid chromatography-mass spectrometry (LC-MS/MS)

    Measured: Every 4 weeks for a total of 12 weeks

  5. C-reactive protein (inflammatory marker)

    High sensitivity C-reactive protein (hsCRP) by standardized methods in a Cobas Mira Plus autoanalyzer (Roche Diagnostics Systems, Madrid, Spain)

    Measured: Every 4 weeks for a total of 12 weeks

  6. oxidized LDL (as oxidative stress biomarker)

    Mercodia Oxidized LDL ELISA kit will be used to measure the oxidized LDL (mU/L).

    Measured: Every 4 weeks for a total of 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 100% Florida OJ and 100% Florida OJ-enriched in people with Cardiovascular Risk Factors, run by Technological Centre of Nutrition and Health, Spain at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Systolic Blood Pressure (time frame: Every 2 weeks for a total of 12 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Feb 2022.
