Study summary

Background:

  • Congenital adrenal hyperplasia (CAH) is a genetic disorder of the adrenal gland. The adrenal gland is located in the abdomen and produces small amounts of hormones such as cortisol, aldosterone, and androgen. These hormones help control blood pressure, protect the body, and maintain good health, especially during development. People with CAH do not make enough cortisol and aldosterone, and make too much androgen. This can lead to serious medical problems. The standard treatment is to take pills that mimic the effects of cortisol and aldosterone. However, treatment with pills can have long-term side effects because of the higher doses needed, and may not work well for some people.
  • A possible new treatment for CAH is to use a pump to deliver cortisol under the skin. Similar pumps are often used to give insulin to people with diabetes. Researchers think that a cortisol pump might be able to help the body use the cortisol more effectively than taking pills. They want to compare the results of a cortisol pump and standard pill treatments for CAH.

Objectives:

  • To compare the effectiveness of a cortisol pump with standard cortisol pill therapy for CAH.

Eligibility:

  • Men and women at least 18 years of age who have CAH (see more details in Eligibility section below).

Design:

  • This study will involve four inpatient hospital stays at the National Institutes of Health in Bethesda, MD over 6 months (spaced 2 months apart). The first and last stays will last about 5 days. The second and third stays will last about 3 days.
  • Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected.
  • At the first study visit, participants will provide regular blood and urine samples. They will also have imaging studies. These studies will look at the bones, fat, and muscles in the abdomen and pelvis.
  • Participants will receive a cortisol pump during the first visit. They will be shown how to use the pump. They will also learn what to do, if they need to take extra "stress dose" cortisol pills.
  • At the second and third visits, the cortisol dose given with the pump will be adjusted as needed. Blood and urine samples will also be collected. No imaging studies are scheduled for these visits.
  • The last study visit will have the same tests as the first visit. Participants will be offered the chance to continue with the pump treatment for 1 more year, or go back to their standard pill treatment.

Read the detailed description

Congenital adrenal hyperplasia (CAH) is a common genetic endocrine disorder, with 21-hydroxylase enzyme deficiency accounting for 95% of the cases. 21-hydroxylase deficiency presents with a spectrum of clinical manifestations ranging from salt-wasting and virilization of female neonates (classic CAH) to symptomatic (precocious puberty, short stature, acne) or asymptomatic hyperandrogenemia (non-classic CAH). Classic CAH is characterized by impaired cortisol and mineralocorticoid biosynthesis, which triggers adrenocorticotropic hormone (ACTH) hyper-secretion and accumulation of adrenal androgens. Glucocorticoid treatment of patients with classic CAH focuses on cortisol replacement and prevention of the ACTH-driven androgen excess. Current conventional glucocorticoid treatment regimens (short or long-acting agents dosed once, twice or thrice daily) have failed to simulate physiological cortisol secretion and suppress adrenal androgen overproduction, without supraphysiologic replacement. Short-term overtreatment with glucocorticoids can lead to iatrogenic Cushing syndrome and long-term use has been associated with the development of obesity, visceral adiposity, insulin resistance and osteoporosis. Isolated case reports have provided evidence that continuous subcutaneous hydrocortisone infusion (CSHI) can mimic physiologic cortisol release and lead to improved CAH control at doses similar to or lower than the traditional treatment. This pilot study aims to test the hypothesis that difficult-to-treat adult patients with classic CAH will have better adrenal androgen control and improved CAH and glucocorticoid-related comorbidities, when they receive near-physiologic cortisol replacement therapy via CSHI compared to conventional glucocorticoid treatment. In addition, this study will provide information on the safety and tolerability of CSHI, and will generate data that will be used in the design of future pediatric studies.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of May 2013, a primary completion of Dec 2016 and a completion of Dec 2016. It does not say whether these dates are actual or estimated.

Results were first posted in Nov 2017, 11 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 22, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
