About this study

Official title: An Exploratory Study to Evaluate the Ability of the Citrus Polyphenol Hesperidin to Improve Insulin Sensitivity in Healthy Subjects and to Ameliorate Insulin Resistance in Obese Subjects

This study will examine whether hesperidin, a major component of citrus fruits, affects how the body responds to insulin in healthy and obese people. Laboratory studies suggest that hesperidin treatment lowers blood pressure, lowers blood sugar and increases blood flow. This study will see if hesperidin improves insulin resistance or insulin's effects on blood flow in people with insulin resistance.

Healthy normal weight or overweight people between 21 and 65 years of age may be eligible for this study. Participants are randomly assigned to take hesperidin or a placebo (inactive dummy pill ) for a 4-week treatment phase.

Read the detailed description

This study will examine whether hesperidin, a major component of citrus fruits, affects how the body responds to insulin in healthy and obese people. Insulin is not as effective in people who are overweight, have high blood pressure or diabetes. This condition is known as insulin resistance. Laboratory studies suggest that hesperidin treatment lowers blood pressure, lowers blood sugar and increases blood flow. This study will see if hesperidin improves insulin resistance or insulin's effects on blood flow in people with insulin resistance.

Healthy normal weight or overweight people between 21 and 65 years of age may be eligible for this study. Participants are randomly assigned to take hesperidin or a placebo (inactive dummy pill ) for a 4-week treatment phase. In addition to treatment, participants undergo the following procedures during the study period:

Screening, including medical history, physical examination and blood and urine tests.

Complete a dietary and physical activity questionnaire and consult with a dietitian

Blood and urine tests

At-home and clinic blood pressure monitoring

Glucose clamp test to measure how the body responds to insulin. This test is done two times during the study. A needle is placed in a vein in each of the subject's arms, one for sampling blood and the other for infusing insulin, glucose and potassium. Glucose and insulin levels, electrolytes, lipids, fatty acids, cytokines and hesperidin levels are measured. We will also use tracer-labeled glucose to determine how much glucose the body produces in the fasting state and during the clamp. This type of glucose has low levels of radiation.

Forearm blood flow measurement with finger plethysmography device. Before beginning the glucose clamp test, a test of how well the blood vessels relax is done. A device that measures the blood flow in the vessels of the forefingers is used. The test is performed at the before the glucose clamp test and again 2 hours after the beginning of the clamp.

What is being measured

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

  1. insulin sensitivity (determined by glucose clamp)

    To determine if oral hesperidin consumption (500 mg p.o. daily for 1 month) improves insulin sensitivity (determined by glucose clamp) in healthy individuals or improves insulin resistance in subjects with obesity when compared with placebo treatment

    Measured: 1 month

Secondary outcomes (4)
  1. basal hepatic glucose production

    Determine whether or not hesperidin treatment reduces basal hepatic glucose production in obese and lean subjects using tracer-labeled glucose.

    Measured: 1 month

  2. endothelial function

    Determine if oral hesperidin consumption (500 mg p.o. daily for 1 month) improves baseline and insulin-stimulated endothelial function as measured by finger plethysmography via Endo-PAT (before and during glucose clamp studies)

    Measured: 1 month

  3. blood pressure

    Determine if oral hesperidin treatment reduces systolic and/or diastolic blood pressure in obese and lean subjects.

    Measured: 1 month

  4. Inflammatory markers

    Determine if oral hesperidin consumption (500 mg p.o. daily for 1 month) alters plasma levels of pro- and anti-inflammatory cytokines

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hesperidin in people with Obesity and Insulin Resistance, run by University of Maryland, Baltimore 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 2 inclusion and 1 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: withdrawn, as of the sponsor's last update on 4 Mar 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 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 was withdrawn before enrolling participants, so there are no results.

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?

insulin sensitivity (determined by glucose clamp) (time frame: 1 month). 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 NCT01773486, 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 4 Mar 2022.
