About this study

Official title: 'A Multicentre, Prospective Randomized Study to Assess the Effect When GnRH Antagonist is Started Either on Stimulation Day 1 and Day 6 vs. Conventional GnRH Agonist Long Protocol in Patients With Polycystic Ovary Syndrome Undergoing IVF-ET

GnRH (Gonadotropin-releasing hormone) antagonists in IVF (in vitro fertilization) has been accomplished by several randomized controlled trials compared with conventional GnRH agonist long protocol in polycystic ovary syndrome (PCOS) patients. Moreover, there are debating issues that refer to the timing of GnRH antagonist initiation. The purpose of this study is to investigate the laboratory and clinical priority during ovarian stimulation for IVF in patients with PCOS treated with three different protocols.

What participants receive

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

  • GnRH antagonist (Cetrorelix)Drug

    Also called Cetrotide

    In the first arm, cetrotide will be administrated from the first day during stimulation. In the second arm, cetrotide will be administrated from the sixth day during stimulation

  • Conventional GnRH agonist (Triptorelin)Drug

    Also called Decapeptyl

    Patients in the agonist group were administered GnRH agonist started 5 days before discontinuation of the oral contraceptive.

What is being measured

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

  1. number of oocyte retrieved

    Measured: ovum pick up day, At the point of ovum pick-up, we can count how many oocyte was retrieved. So, almost just after ovum pick-up, outcome measure will be possible.

Secondary outcomes (1)
  1. pregnancy rate

    Measured: after confirming fetal heart beat via transvaginal ultrasound. Usually 2~4 weeks after ovum pick-up day.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing GnRH antagonist (Cetrorelix) and Conventional GnRH agonist (Triptorelin) in people with Infertility and Polycystic Ovary Syndrome, 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 4 inclusion and 5 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 10 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. 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 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 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?

number of oocyte retrieved (time frame: ovum pick up day, At the point of ovum pick-up, we can count how many oocyte was retrieved. So, almost just after ovum pick-up, outcome measure will be possible.). 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 10 Oct 2017.
