About this study

Official title: Among ICSI Patients Undergoing Antagonist Protocols With Recombinant FSH, Does Replacement of Recombinant FSH by 200 IU of hCG in the Late Follicular Phase Compared With Continuing Recombinant FSH, Result in a Similar Number of Oocytes?

In this study,the investigators compared two protocols for controlled ovarian hyperstimulation in infertility patients requiring IVF. In the control group, the patient undergoes a standard antagonist protocol. In the study group, the administration of gonadotropins is stopped in the late follicular phase and replaced by low dose human chorionic gonadotropins. The primary endpoint of the study is the number of oocytes retrieved in both groups.

What participants receive

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

  • human chorionic gonadotropinDrug

    Also called Pregnyl, NV Organon, Oss, The Netherlands

    hCG 200IU in the late follicular phase

  • recombinant gonadotropinsDrug

    Also called Puregon, NV Organon, Oss, The Netherlands

    200 IU per day during controlled ovarian stimulation

Study groups in NCT00750100
Study groupRoleWhat they receive
AActive comparatorPatients undergo a standard antagonist protocol for in-vitro fertilisation, and are stimulated with recombinant gonadotropins.
Receives: Drug: recombinant gonadotropins
BExperimentalPatients are undergo an antagonist protocol for in-vitro fertilisation and are stimulated with recombinant gonadotropins. When the patient has an estradiol value of 600 ng/L or more and when the patient has at least 6 follicles of 12 mm, the administration of gonadotropins is stopped and replaced by low dose human chorionic gonadotropins.
Receives: Drug: human chorionic gonadotropin

What is being measured

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

  1. Number of oocytes in both treatment groups

    Measured: up to 9 months

Secondary outcomes (1)
  1. Duration of stimulation in both treatment groups, amount of gonadotropins consumed in each treatment group

    Measured: up to 9 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing human chorionic gonadotropin and recombinant gonadotropins in people with Infertility, run by Universitair Ziekenhuis Brussel at 1 site in Belgium.

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 4 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 11 Oct 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 Belgium. 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?

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 oocytes in both treatment groups (time frame: up to 9 months). 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 NCT00750100, 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 11 Oct 2010.
