Trial summary

Gonadotropin-releasing hormone (GnRH) is a hormone that regulates the ability of the pituitary to secrete two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH control the production of female hormones (such as estrogen and progesterone) and the development of eggs by the ovary. Read more about this study

About this study

Official title: Assessment of Sensitivity of the Hypothalamic GnRH Pulse Generator to Estradiol and Progesterone Inhibition in Early Pubertal Girls (JCM026)

Gonadotropin-releasing hormone (GnRH) is a hormone that regulates the ability of the pituitary to secrete two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH control the production of female hormones (such as estrogen and progesterone) and the development of eggs by the ovary. Progesterone and estrogen then decrease the number of GnRH pulses produced by the brain (and therefore the number of LH pulses from the pituitary). The ability to decrease GnRH pulses seems to be very important for normal menstrual function in adult women. The purpose of this study is to learn more about how GnRH and LH pulses are controlled during puberty. The information gathered in this study will hopefully allow us to learn more about how menstrual cycles are normally established in girls during puberty.

Read the detailed description

In this study, the investigators will aim to discover the effect of 7 days of estrogen and progesterone on GnRH pulses in girls in early and mid puberty. Ultimately, if the investigators understand these normal processes, the investigators may be able to better understand abnormalities of puberty.

What participants receive

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

  • ProgesteroneDrug

    oral progesterone suspension (20 mg/ml, 25-100 mg) three times a day at 0700, 1500, and 2300 hr for seven days

  • Estrace (estrogen)Drug

    Also called estradiol

    oral estrace, 0.5-1 mg once a day for seven days

Study groupRoleWhat they receive
Progesterone, estraceExperimentaloral progesterone suspension (20 mg/ml, 25-100 mg) three times a day at 0700, 1500, and 2300 hr to achieve mean plasma concentrations over the range of 2-8 ng/ml for seven days oral estrace, 0.5-1 mg once a day for seven days
Receives: Drug: Progesterone; Drug: Estrace (estrogen)

What is being measured

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

  1. LH Pulse Frequency as a Function of Day 7 Progesterone

    number of LH pulses per 11 hours on Day 7 of progesterone

    Measured: 7 days following oral estrace and progesterone administration

Questions about this trial

What is this clinical trial studying?

A study testing Progesterone and Estrace (estrogen) in people with Hyperandrogenemia and Polycystic Ovary Syndrome, run by University of Virginia at 1 site in United States.

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 4 inclusion and 14 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: stopped early, as of the sponsor's last update on 30 Dec 2020. 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 United States. 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?

Yes. Results are posted in the registry (first posted 30 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

LH Pulse Frequency as a Function of Day 7 Progesterone (time frame: 7 days following oral estrace and progesterone administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Dec 2020.
