About this study

Official title: Phase 1 Study That Will Compare 12 Weeks of Supplementation With Cinnamon Extract on the Action of Insulin and Blood Sugar (Glucose) With 12 Weeks of Supplementation With a Placebo.

The purpose of this study is to determine whether Cinnamon from the Cassae Plant is effective in the body as insulin could lower blood sugar levels.

Read the detailed description

Insulin resistance is a condition in which body cells do not fully respond to the action of insulin, a hormone that controls the amount of sugar (glucose) in the blood. As a result, blood sugar levels become abnormally high. Insulin resistance is common in women with polycystic ovary syndrome (PCOS). This study involves the administration of a nutritional supplement (cinnamon extract). The cinnamon extract like regular cinnamon powder comes from the bark of Cinnamon Cassae plant. It is believed that cinnamon may act in the same way as insulin and therefore could potentially improve insulin resistance and help to lower blood sugar (glucose) levels.

Being tested
Cinnamon Supplementation, Placebo (wheat flour)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cinnamon Supplementation in people with Polycystic Ovary Syndrome and Insulin Resistance, run by Pennington Biomedical Research 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 7 inclusion and 9 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: stopped early, as of the sponsor's last update on 25 Aug 2021. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 stopped early (reason given: Recruitment). Results are not available in the source record.

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 measured by the euglycemic hyperinsulinemic clamp (time frame: 6 months). 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 25 Aug 2021.
