Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Women only
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Female

About this study

Official title: PRE-GAIN Bone Health Pilot Study - Physiologic Replacement of EstroGen for Adolescent Females With AnorexIa Nervosa for Bone Health Pilot Study

This study will assess the affects of an estradiol hemihydrate transdermal system on bone health in 24 adolescent females aged 12-19 years old with anorexia nervosa. Participants in this study will be randomized 1:1 into 2 groups. One group will receive treatment with a transdermal estrogen patch and the other group will not.

Read the detailed description

Currently, no therapy exists to improve bone health in females with anorexia nervosa (AN) other than improving body mass. Transdermal estrogen is being investigated as to whether it has benefit to bone health parameters.

While numerous studies have sought to orally replace estrogen in adolescents and women with AN, the replacement therapy suppresses IGF-1, and as a result oral estrogen studies have demonstrated no bone health benefit in AN. However, transdermal physiologic estrogen, due to no first-pass metabolism in the liver, is not IGF-1 suppressive. IGF-1 is known to be hormone that directly affects bone formation and is considered to be osteoanabolic (helps increase bone mass).

What participants receive

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

  • Estradiol Hemihydrate Transdermal SystemDrug

    Also called PrClimara® 25

    Participants who have had their first period or have a bone age greater than or equal to 14 years will receive PrClimara® 25 (estradiol hemihydrate transdermal system - 25 mcg/day) as a weekly patch, for 24 months. Participants who have not yet had their first period and have a bone age below 14 years will receive an increasing dose of estrogen. These participants will be initiated on graduated dose of transdermal 17-β estradiol patches: 3.1 mcg/day (1/8 patch) for first six-months, 6.2 mcg/day (1/4 patch) for second six-months, 12.5 mcg/day (1/2 patch) for third six-months and 25 mcg/day (full patch) for final six-months.

Study groups in NCT04021017
Study groupRoleWhat they receive
TreatmentExperimentalParticipants randomized to the treatment arm will be divided by maturational status: * Participants who have had their first period or have a bone age greater than or equal to 14 years will receive PrClimara® 25 (estradiol hemihydrate transdermal system - 25 mcg/day) as a weekly patch, for 24 months. o These participants will also receive progesterone (Provera 10 mg tablet) orally every 4 weeks, for 7 days during the second half of the planned menstrual cycle, in order to induce a menstrual period. * Participants who have not yet had their first period and have a bone age below 14 years will receive an increasing dose of estrogen. These participants will be initiated on graduated dose of transdermal 17-β estradiol patches: * 3.1 mcg/day (1/8 patch) for first six-months, * 6.2 mcg/day (1/4 patch) for second six-months, * 12.5 mcg/day (1/2 patch) for third six-months, and * 25 mcg/day (full patch) for final six-months.
Receives: Drug: Estradiol Hemihydrate Transdermal System
No TreatmentNo interventionThe participants in this group will not receive the estrogen patch nor the oral progesterone.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Estradiol Hemihydrate Transdermal System in people with Anorexia Nervosa, run by University of Saskatchewan at 1 site in Canada.

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 8 inclusion and 19 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: withdrawn, as of the sponsor's last update on 16 Dec 2022. 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 Canada. 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 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.

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 was withdrawn before enrolling participants, so there are no results.

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?

Cortical Wall Thickness (time frame: Change from Baseline to Month 24). 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 16 Dec 2022.
