About this study

Official title: To Determine if the Cardiovascular Risk Indices Including Postprandial Hypertriglyceridaemia Are Modified Favourably by Nicotinic Acid (Niacin) in Patients With Polycystic Ovary Syndrome ( PCOS)

Niacin will improve postprandial hyperlipidaemia and cardiovascular risks indices via its lipid lowering as well as via pleiotropic effects in patients with polycystic ovary syndrome (PCOS).

Read the detailed description

Polycystic ovary syndrome is a common hormone problem in young women and, as a result of it, they can experience irregular periods, reduced fertility, acne and increased body hair. Frequently, increased weight is a feature. Research suggests that they could have a higher risk of diabetes, high cholesterol and cardiovascular disease such as high blood pressure, angina, heart attack and stroke.

The fat from the diet is transported from the stomach into the blood and then taken up by the liver, muscles and fat tissues to store or use as an energy source. Delayed removal of fat from the circulation resulting rise of fat after a meal has been known to happen in PCOS. High fats after a meal are a strong risk factor for cardiovascular disease.

Niacin has been in clinical use to lower bad cholesterol and to increase good cholesterol for many years. It has been proved to be effective in reducing risks of heart disease in patients with diabetes. However the effect of niacin on reducing cardiovascular risks and reducing fat level after a meal in PCOS has not been studied and this is why we plan to do this research.

What is being measured

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

  1. Reduction in postprandial triglyceride

    Postprandial triglyceride will be measured using meal test.

    Measured: 3 months

Secondary outcomes (2)
  1. Reduction in high sensitivity C-reactive protein (CRP)

    Measured: 3 months

  2. Improvement in peripheral arterial tone (PAT- index)

    Peripheral arterial tone (PAT- index) will be measured using ENDO PAT 2000 before and after intervention

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing tredaptive (nicotinic acid/ laropiprant) in people with Polycystic Ovary Syndrome, run by Hull University Teaching Hospitals NHS Trust at 1 site in United Kingdom.

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 12 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 15 Jul 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 Kingdom. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Reduction in postprandial triglyceride (time frame: 3 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 NCT01118598, 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 15 Jul 2019.
