Trial summary

The project aims to establish the normal LH and FSH response to a standardized GnRH dose in healthy girls below 6 years of age, and compares the normal GnRH response to the GnRH response in girls with early puberty development. The novel data may help to determine whether the girl is in early puberty or not. Read more about this study

About this study

The project aims to establish the normal LH and FSH response to a standardized GnRH dose in healthy girls below 6 years of age, and compares the normal GnRH response to the GnRH response in girls with early puberty development.

The novel data may help to determine whether the girl is in early puberty or not.

Healthy girls under 6 years of age attending routine examinations including an i.v. line for other causes are included in this study. Our examinations also include bone age determination, Tanner stage determination, and anthropometric measures (height and weight). 10 healthy girls in each of the following age groups: 7-12 months, 12-24 months, 24-36 months, 36-48 months, 48-60 months and 60-72 months are included.

Questions about this trial

What is this clinical trial studying?

A study testing GnRH agonist in people with Precocious Puberty, run by University of Aarhus at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Sep 2013. 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 Denmark. 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.

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 Niels H. Birkebæk, MD PhD (+45 50860090, nielbirk@rm.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

LH response (time frame: 30 minutes). 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 NCT01944488, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?
