About this study

Official title: Acute and Sustained Effects of Plant- Based Bio-Equivalent Nitrate Supplement Tablets on Blood Pressure Reduction, Nitric Oxide Mediated Endothelial Function and Saliva Bioconversion of Dietary Nitrate in Hypertensive Men and Women

The primary purpose of this project is to assess the efficacy (effectiveness) of plant-based nitrate tablets to elevate nitric oxide in your system as measured by saliva and effect on lowering blood pressure (BP), supporting blood vessel function in men and women with hypertension.

Read the detailed description

This clinical trial is to assess the efficacy of plant-based bioequivalent Nitric Oxide supplement for improving blood pressure and endothelial reactivity over a 12 weeks intervention period in individuals with metabolic syndrome. The study also examines the effect of plant-based bioequivalent Nitric Oxide supplement on other markers of cardiovascular function and cardiovascular disease risk including Total, LDL and HDL-Cholesterol, Triglycerides, and a multitude of inflammatory markers.

What is being measured

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

  1. Rate of change in blood pressure

    change in blood pressure (in millimeters of mercury) over twelve weeks under effect of active treatment and placebo

    Measured: 12 weeks

Secondary outcomes (2)
  1. changes in serum, plasma and salivary Nitrite and Nitrate

    change in serum nitrate and nitrate levels (in mcg) over 12 weeks comparing active treatment to placebo

    Measured: 12 weeks

  2. cardiometabolic relevant biomarkers (as compared to placebo)

    measures of serum markers of inflammation (Crp) and glucose over 12 weeks in active vs placebo arms

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Plant based bioequivalent Nitrate supplementation in people with Blood Pressure and Endothelial Dysfunction, run by Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center at 1 site in United States.

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 3 inclusion and 17 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 12 Apr 2019. 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Rate of change in blood pressure (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03909789, which also lists 1 linked publication.

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 12 Apr 2019.
