Trial summary

This study will test a new, extended release form of hydrocortisone called Chronocort in patients with congenital adrenal hyperplasia (CAH). People with CAH do not make enough of the adrenal hormones cortisol and aldosterone, and their adrenal glands make too much of the sex hormone androgen. Read more about this study

About this study

Official title: A Phase 2, Open Label, Crossover Pharmacokinetic and Pharmacodynamic Study to Compare Chronocort Versus Cortef in Patients With CAH

This study will test a new, extended release form of hydrocortisone called Chronocort in patients with congenital adrenal hyperplasia (CAH). People with CAH do not make enough of the adrenal hormones cortisol and aldosterone, and their adrenal glands make too much of the sex hormone androgen. Medicines called glucocorticoids (hydrocortisone, dexamethasone and prednisone) are currently used to treat CAH, but finding the best dose of these drugs that effectively lowers androgens without causing undesirable side effects, such as weight gain and slow growth rate in children, is often difficult to achieve.

Adolescents and adults with CAH due to 21-hydroxylase deficiency may be eligible for this study. Children 16 years of age and older are eligible with confirmation by bone age that they are no longer growing.

Participants undergo the following tests and procedures during two inpatient visits one month apart at the NIH Clinical Center:

  • Medical history and physical examination.
  • Medications: Following 7 days of Cortef (standard drug treatment for CAH), patients begin taking Chronocort on day 3 of hospitalization and continue the tablets once a day for 1 month.
  • Blood tests: A catheter (plastic tube) is inserted in a vein and left in place for frequent blood draws in order to avoid repeated needlesticks. Blood is drawn for chemistries, blood count, pregnancy test in women, and for serial tests (up to 26 samples in a 24-hour period) to measure hormone levels.
  • 24-hour urine test.
  • Height and weight measurements.

Between the two hospitalizations, patients are contacted by NIH weekly to check for possible side effects from Chronocort. Two weeks after the first visit, patients also will have blood drawn by their regular doctor or a local clinic. A few days before the second hospitalization, patients undergo a 20-minute telephone questionnaire about energy level and well being.

About 30 days after discharge from the second hospitalization, patients are followed up with a telephone call to see how they are doing.

Read the detailed description

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a disease of the adrenal cortex characterized by cortisol deficiency with or without aldosterone deficiency, and androgen excess. The severe or classic form occurs in 1 in 15,000 births worldwide, while the mild non-classic form is a common cause of hyperandrogenism. The discovery of glucocorticoid therapy as a treatment for CAH occurred in the 1950's resulting in patients with classic CAH surviving to live a normal lifespan. However, existing treatment is suboptimal and many unresolved clinical problems exist. Standard hormone replacement often fails to normalize the growth and development of children with CAH, and adults may experience iatrogenic Cushing syndrome, hyperandrogenism, infertility or the development of the metabolic syndrome. Chronocort, a newly-developed formulation of hydrocortisone, results in a slow release of hydrocortisone that is designed to mimic the normal cortisol circadian rhythm. This new medical strategy, physiologic cortisol replacement, offers the prospect of an improved outcome of treatment. Chronocort has been safely given to healthy adult males in pharmacokinetic studies. This first ever study in patients with CAH is a pharmacokinetic/pharmacodynamic study comparing Chronocort to Cortef, the conventional immediate-release form of hydrocortisone.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Chronocort and Cortef in people with Congenital Adrenal Hyperplasia and 21-Hydroxylase Deficiency, run by Neurocrine UK Limited 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 5 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 26 Apr 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 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.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Aug 2014). 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?

Chronocort vs. Cortef Cortisol Concentrations (AUC Over 24 Hours - Time Points 0,.5,1,1.5,2,3,4,5,6,7,8,10,10.5,11, 11.5,12,13,15,17,17.5,18,18.5,19,20,22,24 Post Dose). (time frame: Cortef after one week, Chronocort after one month). 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 NCT00519818, which also lists 3 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 26 Apr 2022.
