About this study
Background: PCOS is a common condition with a prevalence of 5-8 % in premenopausal women. More than 50% of PCOS patients are insulin resistant and have a diabetes risk 5-8 times higher than age- and weight-matched controls. Studies using insulin sensitizers in PCOS found increased insulin sensitivity and decreased insulin levels to be followed by decreased androgen levels and improved ovulatory function. No studies however, evaluated the long term effects of insulin sensitizing treatment.
Oral contraceptives normalize menstrual cycles and suppress androgen levels in PCOS, however no long-term studies evaluated the effects of combined treatment with metformin and oral contraceptives in PCOS.

Design: Randomized open study in 3*30 PCOS patients. Patients are randomised to 24 months of treatment with 1: metformin, 2: metformin and oral contraceptives or 3: oral contraceptives.
Primary outcome measures: fasting insulin, AUC insulin. Secundary endpoints: BMI, WHR, LH, FSH, total and free-testosterone, c-peptid, urinary cortisol, AUC for insulin, glucose and c-peptid during OGTT.
Inclusioncriteria:
- Irregular menses or anovulaty cycles
- High free testosterone > 0,035 nmol/l or hirsutism
- PCO in vaginal US Criteria 1 and 2 OR 2 and 3.
Design:
Read the detailed description
90 patients are included and randomized to 12 months of treatment with metformin (1000+1000 mg/d) or OCP (150 mg desogestrel 30 microgram ethinylestradiol) or combined treatment (metformin+OCP).
Patients attend a biochemical and physical examination at study inclusion and at 12 months. Patients attend for registration of side effects and compliance after 6 months of study duration. Safety tests are performed at all three visits and include weight, blood pressure, HbA1c, liver enzymes, electrolytes, and white blood cell count. Pregnancy tests are performed by the participants each month. Patients are given general advice on lifestyle intervention. Patients are excluded if they initiated medical treatment with possible hormonal and metabolic effects during the intervention period. Lifestyle intervention is allowed. Laser treatment is offered to patients with moderate or severe facial hirsutism and patients are allowed to shave/wax. The patients accept not applying cosmetic treatment 3-4 days before attending for evaluation at the clinic.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Metformin and Desorelle in people with Polycystic Ovary Syndrome, run by Odense University Hospital at 1 site in Denmark.
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 3 inclusion and 8 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 13 Apr 2015. 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 Denmark. 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?
Changes in fasting insulin and area under the curve for insulin (2 hours) (time frame: 12 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 NCT00451568, 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 13 Apr 2015.
