Frequently asked questions about Hydrocortisone Modified Release

What is hydrocortisone modified release?

Hydrocortisone modified release is an investigational oral small molecule developed by Neurocrine Biosciences, Inc. (ticker NBIX). It is being studied in endocrine disease, specifically for adrenal insufficiency and congenital adrenal hyperplasia. The formulation is designed to release hydrocortisone in a modified manner, and it is also referred to as hydrocortisone modified release capsules.

What is hydrocortisone modified release used for?

Hydrocortisone modified release is being studied for endocrine disease, including adrenal insufficiency and congenital adrenal hyperplasia. It is an investigational therapy and has not been established as a treatment for these conditions. The clinical program has focused on adults with congenital adrenal hyperplasia, a condition in which the adrenal glands do not produce sufficient cortisol.

What does hydrocortisone modified release target?

Hydrocortisone modified release targets NR3C1, the glucocorticoid receptor, and acts as an agonist at that receptor. By binding and activating NR3C1, the drug is intended to provide glucocorticoid replacement. NR3C1 agonism is the mechanism underlying hydrocortisone's physiologic effects in endocrine replacement therapy.

Who makes hydrocortisone modified release?

Hydrocortisone modified release is being developed by Neurocrine Biosciences, Inc., which trades under the ticker NBIX. The company is the sponsor of the clinical program evaluating this modified release hydrocortisone formulation in endocrine disease.

What phase is hydrocortisone modified release in?

Hydrocortisone modified release is in Phase 2 development. It is an investigational product and is not approved by the FDA. The Phase 2 program has completed one trial, and no active trials are currently listed for this asset.

What clinical trials is hydrocortisone modified release in?

Hydrocortisone modified release has been evaluated in one completed Phase 2 trial, NCT01735617, titled a pilot study to characterize and examine the pharmacokinetics and efficacy of Chronocort in adults with CAH. The trial enrolled 16 participants in the United States, included adults 18 years and older, and was uncontrolled, non-randomized, and not double blinded.

Is hydrocortisone modified release the same as hydrocortisone modified release capsules?

Yes. Hydrocortisone modified release capsules is an alternative name for hydrocortisone modified release, the investigational oral formulation developed by Neurocrine Biosciences, Inc. (NBIX). Searches using either name refer to the same Phase 2 endocrine asset being studied in adrenal insufficiency and congenital adrenal hyperplasia.
