About this study

Official title: The Effects of Oral Cinnamon Extract on Menstrual Cyclicity in PolyCystic Ovary Syndrome

The primary purpose of this follow-up study is to determine if cinnamon can restore menstrual cyclicity in Polycystic Ovary Syndrome (PCOS) subjects with oligomenorrhea. As a secondary purpose, the investigators intend to confirm the salutatory effect of cinnamon on insulin resistance in larger group of study subjects.

Polycystic ovary syndrome (PCOS) is a very common condition found in women of childbearing age. PCOS patients often have irregular periods, extra hair growth, or difficulty becoming pregnant. The syndrome can also be associated with more serious conditions such as heart disease, diabetes, or cancer of the uterus. Although no one knows the cause of the syndrome, scientific studies showed that having too much insulin can be one of the reasons. In fact, almost every overweight woman with PCOS has been found to have high insulin levels.

Recently studies using rats and mice have shown that a commonly used spice, cinnamon, may also reduce the body's insulin level. Another study showed that daily use of cinnamon for forty days lowered the blood sugar level in patients with diabetes. Our own study also showed that using cinnamon everyday for 8 weeks decreased insulin resistance in women with PCOS. The purpose of this study is to see if cinnamon can help women with PCOS have more regular periods.

Read the detailed description

All patients will eat a balanced diet containing 1800 calories per day, but half of the patients in the study will take pre-made cinnamon extract pills three times a day, while the other half will take placebo pills (pills with no cinnamon extract) three times a day for 6 months. During this time, every patient will keep track of her period on a calendar.

Blood tests measuring insulin, substances important for insulin action, cholesterol, and glucose (sugar) will be taken before and after the 6 months of medication. A total of 8 separate visits will be needed to finish the study. At the end of the study, the investigators will then compare the number of periods, blood glucose, insulin, and cholesterol levels between the patients that took cinnamon and the patients that took placebo.

What is being measured

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

  1. Number of Menses During the Six Month Study Period.

    Ovulatory cycles will be confirmed by serum progesterone levels.

    Measured: Up to 6 months

Secondary outcomes (2)
  1. Change in Insulin Resistance

    The changes in insulin resistance parameters in overweight patients with PCOS between baseline and after 6 months of daily cinnamon compared to the corresponding change in patients receiving 6 months of placebo. Higher values of insulin resistance represent a worse outcome. A higher value Homeostasis Model of Insulin Resistance indicates more insulin resistance so higher values are worse outcomes (a score of >2 is considered healthy for adults with scores >5 being considered severe insulin resistance). For the Quant. Insulin Sensitivity Check Index, a lower value indicates more insulin resistance so lower values are worse outcomes (values can range from .45, which is considered normal in health individuals and .30, which is characteristic of diabetes).

    Measured: Baseline and 6 months

  2. Change in Glucose Response

    Change in Glucose Response - area under the curve (AUC), trapezoidal method - in overweight patients with PCOS between baseline and after 6 months of daily cinnamon compared to the corresponding change in patient receiving 6 months of placebo. Fasting blood samples were drawn followed by a 2 hour glucose tolerance test with blood draws at 30, 60, and 120min post glucose ingestion.

    Measured: Baseline and 6 Months - fasting bloods, followed by glucose tolerance test with draws at 30, 60, and 120 minutes post glucose ingestion

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cinnamon Extract in people with Polycystic Ovary Syndrome, run by Rogerio A. Lobo 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 4 inclusion and 10 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 3 Oct 2017. 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 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?

Yes. Results are posted in the registry (first posted 2 Aug 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Menses During the Six Month Study Period. (time frame: Up to 6 months). 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 NCT01483118, 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 3 Oct 2017.
