Atumelnant (INNTooltip International Nonproprietary Name; developmental code name CRN04894) is an investigational new drug developed by Crinetics Pharmaceuticals for the treatment of adrenocorticotropic hormone (ACTH)-dependent endocrine disorders.[1] It is a selective antagonist of the melanocortin type 2 receptor (MC2R), also known as the ACTH receptor, which is primarily expressed in the adrenal glands.[1][2] The drug is orally active.[1] Atumelnant is being evaluated to treat conditions such as congenital adrenal hyperplasia (CAH) and ACTH-dependent Cushing's syndrome caused for example by pituitary adenomas.[3]
