About this study

Official title: Randomized Controlled Trial Comparing the Effect of GnRH Agonist and Antagonist Ovarian Stimulation Protocols in PCOS Patients

The purpose of this study is to compare pregnancy rates and the occurrence of OHSS in PCOS patients who were treated with GnRH agonist and GnRH antagonist protocols ovarian stimulation during an IVF cycle. Our hypothesis is that the GnRH antagonist protocol reduces the occurrence and severity of OHSS compared to the GnRH agonist protocol.

Read the detailed description

Women with polycystic ovarian syndrome (PCOS) represent a group of patients at high risk of developing ovarian hyperstimulation syndrome (OHSS), an iatrogenic complication of ovarian stimulation during IVF treatment. In contrast to mild OHSS, severe OHSS is a life-threatening complication, characterized by massive ovarian enlargement, ascites, pleural effusion, oliguria, haemoconcentration and thromboembolic phenomena. Currently, no curative therapy for OHSS is available and thus prevention is considered the most effective "treatment". Several measures have been adopted to reduce the occurrence of the syndrome, the most effective being cycle cancellation and withholding of human chorionic gonadotropin (hCG), which seems to be the most critical factor for the development of OHSS.

COMPARISON: This study aims to compare the development and severity of OHSS, as well as ongoing pregnancy rates in PCOS patients who received a flexible GnRH antagonist (Ganirelix) protocol vs a long GnRH agonist (Arvekap) protocol of ovarian stimulation.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Arvekap 0.1mg (Triptorelin, Ipsen, France) and Ganirelix 0.25mg (Orgalutran, Organon, The Netherlands) in people with Polycystic Ovary Syndrome and Ovarian Hyperstimulation Syndrome, run by Eugonia at 1 site in Greece.

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 1 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 29 Dec 2006. 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 Greece. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Tryfon Lainas, PhD (00302107236333, ivf@eugonia.com.gr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Development of OHSS. The study lists 2 primary outcomes in all. 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 NCT00417144, which also lists 2 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 29 Dec 2006.
