About this study

Insulin resistance has important implications in the pathogenesis of the polycystic ovary syndrome (PCOS) and insulin-sensitizing drugs are considered a useful therapeutic approach.

Reduction of insulin levels with administration of insulin sensitizing agents has been found to be beneficial in lowering both hyperinsulinemia, hyperandrogenemia, and restoring ovulation. Metformin alone or in combination with oral contraceptives (OCs) has been widely used in the long term treatment of women with PCOS in whom it modifies the ovarian morphology, improves intraovarian androgen levels, and enhances systemic and local insulin resistance. Despite to these beneficial effects, several side effects have been reported due to the long term administration of this drug.

In the recent years, inositol has found more and more space in the reproductive clinical practice. Indeed, inositol have been classified as "insulin sensitizing agent" and it is mainly used as a chronic treatment for PCOS. Inositol exists in 9 different isomers and in particular several studies on Myo-inositol and D-chiro-inositol were reported.

In this study myo-inositol versus D-chiro-inositol treatments were compared to placebo in women with PCOS and with or without insulin resistance.

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 1 inclusion and 3 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 23 Jan 2012. 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 Italy. 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. 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?

Body Mass Index (BMI). The study lists 24 primary outcomes in all. 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 NCT01514942, which also lists 4 linked publications.

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 23 Jan 2012.
