What participants receive

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

  • Low dose (1 mcg) ACTH stimulation testOther

    Subjects will have baseline cortisol and ACTH drawn followed by administration of 1 mcg/m2 (max 1 mcg) of cortrosyn. Blood will be drawn at 20 and 40 minutes post cortrosyn for peak cortisol assessment of central adrenal insufficiency.

  • Overnight metyrapone testOther

    Subjects will receive metyrapone 30 mg/kg (max 3 grams) by mouth at midnight. Blood will be drawn at 0800 AM the following morning for ACTH, cortisol and 11 deoxycortisol for assessment of central adrenal insufficiency.

Assessment of Central Adrenal InsufficiencyOtherPatients will undergo low dose ACTH stimulation test followed by overnight metyrapone test to assess for central adrenal insufficiency.
Receives: Other: Low dose (1 mcg) ACTH stimulation test; Other: Overnight metyrapone test

What is being measured

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

  1. Presence of central adrenal insufficiency using low dose (1 mcg) ACTH stimulation test

    Measured: 40 minutes

  2. Prescence of central adrenal insufficiency using overnight metyrapone test

    Measured: 8 hours

Secondary outcomes (1)
  1. Determine peak cortisol value on low dose (1 mcg) ACTH stimulation test that can accurately predict central adrenal insufficiency based on overnight metyrapone test with good sensitivity and specificity.

    Measured: 0

Questions about this trial

What is this clinical trial studying?

A study testing Low dose (1 mcg) ACTH stimulation test and Overnight metyrapone test in people with Prader Willi Syndrome and Adrenal Insufficiency, run by Nationwide Children's Hospital 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 1 inclusion and 3 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 29 Jan 2018. 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?

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?

Presence of central adrenal insufficiency using low dose (1 mcg) ACTH stimulation test (time frame: 40 minutes). 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?
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 29 Jan 2018.
