About this study

Official title: Is the Clinical Outcome Affected by the Incidence of Progesterone Elevation on the Day of hCG Triggering When Agonist Protocol is Compared to Antagonist Protocol for IVF

The aim is to explore whether the incidence of progesterone rise in the late follicular phase differs between GnRH-agonist and GnRH-antagonist protocols for IVF and whether this has an impact on the probability of pregnancy achievement.

Read the detailed description

In view of the current debate concerning possible differences in efficacy between the two GnRH analogues, the current study aimed to explore whether progesterone control in the late follicular phase differs when GnRH-agonist is used as compared to GnRH-antagonist and if so to what extend does the progesterone rise have an impact on the probability of achieving a pregnancy.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing In vitro fertilization in people with Pregnancy Outcome After In Vitro Fertilization (IVF), run by Universitair Ziekenhuis Brussel 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 3 inclusion and 3 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 15 Sep 2010. 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?

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?

Incidence of late progesterone rise on the day of HCG triggering (time frame: Up to delivery (2010)). 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 NCT01191710, 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 15 Sep 2010.
