    Measured: 3 month after surgery

Secondary outcomes (8)
  1. Compare the mean change of serum AMH level

    Measured: 1 month after surgery

  2. Compare the trend of mean change of serum AMH level

    Measured: 1 and 3 month after surgery

  3. Compare the mean change of serum AMH level

    Measured: baseline and after preoperative dienogest/placebo therapy for 3 months

  4. Compare the revised American fertility society (AFS) score

    Measured: At surgery

  5. compare the surgical time (minute)

    surgical time (minute)

    Measured: intraoperative

  6. Brief Pain Inventory (BPI) scores

    Measured: baseline, 1 month after surgery and 3 month after surgery

  7. number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Measured: All adverse events from randomization to postoperative 3 months

  8. Mean change of diameter of endometrioma measured by ultrasonography after preoperative dienogest/placebo therapy for 3months

    Measured: baseline and after preoperative dienogest/placebo therapy for 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dienogest and Surgery in people with Ovarian Reserve and Endometriosis, run by Seoul National University Hospital at 1 site in South Korea.

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 5 inclusion and 13 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The record says: withdrawn, as of the sponsor's last update on 31 Oct 2017. 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 South Korea. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 withdrawn before enrolling participants, so there are no results.

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?

Compare the mean change of serum Anti-Mullerian Hormone (AMH) level (time frame: 3 month after surgery). 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 31 Oct 2017.
