About this study

Official title: Ovarian Stimulation With FSH Alone Versus FSH Plus a GnRH Antagonist in an Oocyte Donor/Recipient Programme: a Protocol for a Non-randomised Multicenter Study

The aim of this study is to compare the efficacy of a protocol using FSH alone with that of a protocol using FSH plus a GnRH antagonist for controlled ovarian hyperstimulation in cycles of elective freezing in the context of a donor/recipient programme.

Read the detailed description

The hypothesis to be tested is that an ovarian stimulation protocol that includes FSH alone without any LH surge prevention regimens is not inferior to a protocol including FSH plus a GnRH antagonist in terms of clinical outcome in a donor/recipient model.

The formal sample size is calculated as follows:

If there is a true difference in favour of the experimental treatment of 5% (20% vs 15%), then 160 patients (80 per group in case of 1:1 enrolment) are required to be 80% sure that the upper limit of a one-sided 95% confidence interval (or equivalently a 90% two-sided confidence interval) will exclude a difference in favour of the standard/control group of more than 10%.

In the context of the present pilot study (as a first stage), the investigators intend to study 50 patients (25 per group in case of 1:1 enrolment). At a second stage the above mentioned sample size will be used.

What participants receive

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

  • GnRH antagonistOther

    The GnRH antagonist in the control group (standard therapy) is administered from day 6 of FSH treatment at the dose of 0.25 mg per day until the triggering day and is injected each time immediately after the injection of FSH.

Study groups in NCT05759871
Study groupRoleWhat they receive
FSH only (no GnRH antagonist)ExperimentalWomen receive only FSH starting on day 2 of the cycle. The starting dose of FSH is 225-300 IU s.c. for the first 4 days adjusted thereafter according to the ovarian response.
Receives: Other: GnRH antagonist
FSH + GnRH antagonistActive comparatorWomen receive 225-300 IU s.c. FSH, and a GnRH antagonist from day 6 of FSH treatment at the dose of 0.25 mg per day until the triggering day. The GnRH antagonist in group 2 is injected each time immediately after the injection of FSH.
Receives: Other: GnRH antagonist

What is being measured

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

  1. Rate of LH secretory peaks

    A secretory peak of LH is defined as the increase at levels ≥10 IU/l.

    Measured: 3 weeks after start of ovarian stimulation.

  2. Rate of concentration of progesterone >1 ng/ml

    Concentration of progesterone elevation >1 ng/ml

    Measured: At any time within 3 weeks after start of ovarian stimulation.

Secondary outcomes (2)
  1. Rate of ongoing clinical pregnancy

    Clinical pregnancy (fetal heart beat) at ultrasound

    Measured: 12 weeks after last menstrual period

  2. Rate of miscarriage

    Miscarriage / Loss of the embryo

    Measured: Within 20 weeks after last menstrual period

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing GnRH antagonist in people with Premature Luteinisation and Progesterone Elevation, run by National and Kapodistrian University of Athens.

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 6 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 10 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Results are not available in the source record.

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

Contact Ioannis Messinis, Prof (6944370627 ext. 0030, messinis.io@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of LH secretory peaks (time frame: 3 weeks after start of ovarian stimulation.). 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 NCT05759871, which also lists 5 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 10 Mar 2023.
