Primary adrenal insufficiency
MONDO:0015128A hormonal disorder that occurs when the adrenal glands fail to release adequate amounts of glucocorticoids (cortisol), mineralocorticoids (aldosterone, 11-deoxycorticosterone), and androgens (dehydroepiandrosterone) to meet physiologic needs, despite release of ACTH from the pituitary.
Also known as: Addison's disease

Can a modified hydrocortisone mimic the Body's natural cortisol rhythm?
Disease control CompletedResearchers are testing Chronocort, a modified-release form of hydrocortisone, against standard immediate-release hydrocortisone in 30 healthy male volunteers. The study measures how the drug moves through the body, including how fast it reaches peak levels and how long it stays …

Can a Timed-Release hydrocortisone pill match the Body's overnight hormone rhythm?
Disease control CompletedResearchers are testing several modified, timed-release versions of hydrocortisone, a hormone drug, in healthy male volunteers. The study has two parts: one compares how six different formulations move through the body after a single nighttime dose, and the other checks whether t…

New pill could tame rare hormone disorder
Disease control CompletedThis study tested a new oral drug called atumelnant in 38 adults with classic congenital adrenal hyperplasia, a genetic condition causing hormone imbalances. The drug works by blocking a hormone receptor to lower excess adrenal hormones. Researchers measured safety, side effects,…
