What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cyproterone Acetate + estradiolDrug

    Also called Androcur, Provames

    PCOS will receive:

    50mg cyproterone acetate (Androcur®) in combination with p.o. 2mg estradiol daily

  • Levonorgestrel, Ethinyl Estradiol 0.1-0.02Mg Oral TabletDrug

    Also called Leeloo Gé®

    Healthy volunteers receive combined oral contraceptive (COC) consisting 0.02 mg ethinylestradiol and 0.1mg of progestins (Leeloo Gé®)

Study groups in NCT03043924
Study groupRoleWhat they receive
PCOS womenOther26 PCOS women who receive consultation for hyperandrogenism needing treatment with Cyproterone Acetate + estradiol will be recruited.
Receives: Drug: Cyproterone Acetate + estradiol
Healthy volunteersOther26 Healthy volunteers subjects who receive consultation contemplating oral contraceptives (Levonorgestrel, Ethinyl Estradiol 0.1-0.02Mg Oral Tablet ) will be recruited.
Receives: Drug: Levonorgestrel, Ethinyl Estradiol 0.1-0.02Mg Oral Tablet

What is being measured

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

  1. Change in the Apparent Diffusion Coefficient (ADC)

    The change in the ADC will be analyzed in healthy volunteers and PCOS women before starting the oral contraceptives, and next during the third sequence of treatment.

    Measured: Baseline and 3 months after treatment start

Secondary outcomes (5)
  1. Change in the metabolite concentrations

    The change in the metabolite concentrations will be analyzed in the two groups before starting the oral contraceptives, and next during the third sequence of treatment.

    Measured: Baseline and 3 months after treatment start

  2. Correlation coefficient (Spearman or Pearson) between the ADC and serum hormonal levels (FSH,luteinizing hormone,oestradiol, AMH)

    The correlation between ADC and hormonal levels in the two groups will be analysed before starting the contraceptive treatment and during the third processing sequence.

    Measured: Baseline and 3 months after treatment start

  3. Correlation coefficient (Spearman or Pearson) between the metabolite concentrations and serum hormonal levels (FSH, luteinizing hormone, oestradiol, AMH)

    The correlation between metabolite concentrations and hormonal levels in the two groups will be analysed before starting the contraceptive treatment and during the third processing sequence.

    Measured: Baseline and 3 months after treatment start

  4. Plasma GnRH concentration before and after treatment (PCOS patient and control group)

    Measured: Baseline and 3 months after treatment start

  5. Correlation between brain metabolite concentrations and plasma GnRH concentration before and after contraception.

    Measured: Baseline and 3 months after treatment start

Questions about this trial

What is this clinical trial studying?

A study testing Cyproterone Acetate + estradiol and Levonorgestrel, Ethinyl Estradiol 0.1-0.02Mg Oral Tablet in people with Polycystic Ovary Syndrome, run by University Hospital, Lille at 1 site in France.

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 14 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 11 Dec 2025. 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 France. 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.

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?

Change in the Apparent Diffusion Coefficient (ADC) (time frame: Baseline and 3 months after treatment start). 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 NCT03043924, 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 11 Dec 2025.
