Trial summary

About this study

Official title: Determination if Oral DCI Administration to Women With PCOS Increases Total DCI Content in Urine and Blood...

To determine if oral DCI administration to women with PCOS increases the total DCI content in urine and blood, and, if so, if that change is accompanied by i) an increase in DCI-IPG release in blood (as determined by bioactivity) during an oral glucose challenge and ii) an increase in whole-body insulin sensitivity.

Read the detailed description

A total of 46 women will be studied. We will study 23 obese and 23 non-obese women. There will be no BMI restriction. Twenty-three women will be randomly assigned to receive DCI (experimental group) and 23 women to receive placebo (control group). The women will be studied during the equivalent of the follicular phase of the cycle, as documented by a serum progesterone concentration of 2 ng/ml.

PCOS will be defined using criteria developed at the 1990 NICHD conference on PCOS3 - i.e., all women will have oligomenorrhea (eight or fewer menstrual periods annually) and hyperandrogenemia (elevated serum total or free testosterone concentration), and secondary causes of hyperandrogenism or ovulatory dysfunction will be excluded (see below: Entrance Criteria). All women will undergo a standard oral glucose tolerance test (OGTT) to screen for diabetes mellitus,16 but impaired glucose tolerance (IGT) will not be an exclusion criteria because of the high prevalence of IGT in this population.8,17-19 We intentionally will not screen the women for the presence of insulin resistance. Women with PCOS who have disorders associated with insulin resistance - such as hypertension21-23 or dyslipidemia21-23 - will not be excluded as long as they have been on a stable dose of medication for 6 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing DCI in people with Polycystic Ovary Syndrome, run by Virginia Commonwealth University 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 0 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 16 Nov 2011. 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 combined 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.

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?

The study was stopped early. 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?

To determine if oral DCI administration to women with PCOS increases the total DCI content in urine and blood. (time frame: 43 days). 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 16 Nov 2011.
